Vacuum drum filter safety requirements analysis Drum vacuum filter, English: rotaryvacuumdisk-fiter. A type of continuous filter. The construction is similar to the drum vacuum filter and the operating principle is the same. A negative pressure is used as a filter to filter the continuous filter on the surface of the cylindrical drum. This filter was originally used in the alkali and mining industries, and later extended to the chemical, coal and sludge dewatering sectors. 1 When the system is in normal operation, the granulated water volume, the amount of purge air, the amount of sweep water, the maximum water temperature of the granulator and the slag flow rate shall reach the design specifications. 2 When the system is running, the equipment inspection should meet the following requirements: the equipment is not abnormal, the granulation head is not blocked, the tank grille is free of slag blocks, the high and low ditch, the slag gate is in a reasonable state, there is no slag in the hot water tank, and there is no slag in the pit. Water and slag, no leaks in each pipeline valve, smooth tape transportation, no deviation, normal water level. 3 The slag ditch used in the tapping shall have the conditions for diverting the dry slag or other measures for treating the slag. The time for diverting the shunt shall not exceed 3 min. 4 During normal production, the operation of the system equipment should be automatically controlled. 5 The system should be started 20 minutes before the tapping, and the signal is [ready", and the operating room can start the system. A startup fails and should not be started immediately. 6 When the system is in danger of personal injury and equipment safety, stop the system operation immediately and pour the hot residue into the dry slag pit or slag tank. 7 When the iron is discharged, there should be no people near the slag ditch and the granulator. 8 should pay close attention to the amount of granulated water in the system. If it is...

Cylinder vacuum filter First, the cylinder type vacuum filter Vacuum filter is cylindrical metal ore dressing plant most especially black concentrator applications dewatering equipment. According to its unloading method, it can be divided into various types. Figure 1 is a continuous filtering device that can simultaneously perform operations such as filtration, washing, and cake removal in the same rotating device. The cylinder is a cast or steel plate welded cylinder whose outer surface is divided into a plurality of filter chambers by a grooved lattice plate. The filter cloth is covered on the grid plate. The lower part of the cylinder is immersed in the slurry tank and is rotated around the horizontal axis by the gear system. The size of the filter chamber should not be too wide, generally not exceeding 550 mm. The number is related to the diameter of the cylinder. When the diameter is large, the outer surface area of the cylinder is large, and the number of filter chambers is correspondingly increased. Conversely, the number of filter chambers is correspondingly reduced. For example, a commonly used 40 m 2 filter has 24 filter chambers. The outer filter type vacuum filter uses a scraper to drop the filter cake. The filter cloth is fastened to the filter plate by means of a wire . These wires also serve to prevent the filter cloth from being scratched by the scraper. The outer filter vacuum filter has a stirrer in the slurry tank, which is located below the cylinder and is driven by the bevel gear and the chain. When the agitator is working, the slurry can be kept in suspension in the trough. The number of times of agitation depends on the nature of the material, and is generally 20-60 beats/min. For materials with a large particle size and coarse density, the number of stirrings can be large. The dispensing head is an important part of the filter. The filtrate is discharged through it, and suction and pressure are alternately carried out during the filtration...

Combined baler/bundle packing machine Patent Name Combined Balers/Bundle Packaging Machines Patent Applicant WELLMATION CO., LTD. Principal Applicant, Ireland Mayo County Inventor P.C. McHale; M.W. McHale; J.J. N.G.P. Sheridan; P. T. O'Connor; J.P. Bikins Application (Patent) No. 02809705.X Date of Application 2002.03.22 Certification Date Approval Notice No. 1531392 Audit Day 2004.09.22 Specification CD-ROM D0438 Main classification number A01F15/07 Classification No. A01F15/07 Sub-item Original Application No. Priority Citation Abstract A combined baler/bundle packing machine (1) including a chassis (5) on which the chassis is mounted There are balers (10) and bale packing machines (11). The baler (10) comprises a fixed part (18), a lower part (19) and an upper part (20) each carrying a bale forming roll (25), the roll (25) defining the bale forming chamber (15), a circular material A bundle (2) is formed inside the chamber (15). The lower part (19) and the upper part (20) are respectively rotated around the first and second pivots (35), (40) from the bale forming position (Fig. 5) to the unloading position (Fig. 1) to directly move the bale from The bale forming chamber (15) is sent upwards and backwards to the first and second stock support rollers (50) in the bale wrapping machine (11). The bale support roller (50) rotates the bale (2) about the first package axis (53), while the carrying ring (55) rotates a pair of wrapping material dispensers (54) about the second horizontal package axis (56) to The packaging material is dispensed onto the bale (2) to pack it. The combined baler/bundle packer is efficient, compact and small in length. Sovereignty Item 1. A modular baler/binder wrapper for forming a cylindrical bale and packaging it with a wrapping material, the baler/bundling baler including a bale for forming bales Machine, the baler having a bale forming chamber, a bale formed therein, a bale wrapping device for receiving the bale from the baler, wrapping...
