DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention is a fully automatic gravity circulation plate pulling cantilever filter press, comprising a frame body 1 and an oil cylinder 2 arranged on one side of the frame body 1, a hydraulic station 3 for providing a power source to the oil cylinder 2 is arranged on one side of the frame body 1, and a clamping plate body 4 is arranged on the top of the frame body 1; a plate pulling assembly 5 is arranged on the top of the frame body 1, and the plate pulling assembly 5 comprises a passive sprocket assembly 501 and a transmission assembly 502 arranged on the frame body 1, and the passive sprocket assembly 501 and the transmission assembly 502 are connected by two transmission chains 503 for transmission, and a reduction motor 504 for driving the transmission assembly 502 to rotate is installed on the frame body 1, and a plate pulling claw assembly 6 is installed on the two transmission chains 503. The frame body 1 and the clamping plate body 4 are used as the main force-bearing structures of the equipment, and high-quality carbon thick steel plates are used, and the thickness ranges from 40 to 100 mm. Compared with the traditional grid frame structure, this structure has better mechanical properties and also reduces the production error caused by welding deformation.

[0019] A feeding plate 7 is provided on one end of the frame body 1 away from the oil cylinder 2 .

[0020] Among them, a suspension beam assembly 8 is provided at the top of the frame body 1, and filter plate assemblies 9 are provided on both sides of the frame body 1. The filter plate assembly 9 is suspended and positioned by rollers from above the filter plate. This form has greatly improved the operating space of the filter plate compared with the traditional two-side positioning. Due to the traditional side beam type, the two sides will be blocked by the beams, which has certain obstacles to the operation and observation of the filter plate. This suspension beam type, because the positioning side is at the top and there are no obstacles on both sides, has a larger space for filter plate operation and a better observation field of view, which greatly improves the space for the filter plate assembly 9.

[0021] Among them, the plate pulling claw assembly 6 includes a plate pulling claw 601 arranged between the two transmission chains 503 and abutting against the filter plate assembly 9, the plate pulling claw assembly 6 also includes a plate pulling claw positioning pin 602 and a plate pulling claw fixing pin 603 arranged on the two transmission chains 503, the plate pulling claw 601 is fixed on the plate pulling claw positioning pin 602 and the plate pulling claw fixing pin 603, the plate pulling claw fixing pin 603 is sleeved with a spacer sleeve 604, the plate pulling claw assembly 6 is composed of the plate pulling claw 601 as a main component, wherein one end of the plate pulling claw 601 is fixed by the plate pulling claw fixing pin 603, and the other end is a movable end, which is limited by the plate pulling claw positioning pin 602, so that the plate pulling claw 601 can make a certain up and down movement around the fixed end due to the downward self-weight generated by the deflection. At this time, the movement displacement can be adjusted by the difference in diameter between the aperture of the movable end and the plate pulling claw positioning pin 602 to achieve up and down movement.

[0022] Wherein, a cylinder seat 10 for mounting the cylinder 2 is provided at one end of the frame body 1 .

[0023] The top of the frame body 1 is connected to a tension beam 12 via a locking nut 11 .

[0024] Among them, one side of the frame body 1 is connected to a filter cloth cleaning mechanism 13 via a linear electric guide rail, the top of the filter cloth cleaning mechanism 13 is provided with a back-blowing component 1301 and a water inlet pipe 1302 arranged on the frame body 1 and connected to the back-blowing component 1301, a chain is provided on the frame body 1, and a water spraying mechanism is provided on the chain. The water spraying mechanism is driven up and down by the upper and lower driving motors through the chain. After completing a cloth washing procedure, the cloth washing mechanism will move forward again to start the next cloth washing procedure. The filter cloth cleaning mechanism 13 adopts an embedded water spraying structure with a compact structure and good protection performance.

[0025] During operation, the hydraulic station 3 is used as a power source to drive the oil cylinder 2 to drive the clamping plate body 4 to make a reciprocating motion. When the oil cylinder 2 moves forward, the equipment reaches the pressure holding pressure, the hydraulic station 3 stops working, and the equipment starts to feed. After the equipment feeds, the oil cylinder 2 retreats to the initial position driven by the hydraulic station 3, and the pull plate assembly 5 starts to run at this time. The pull plate assembly 5 uses the reduction motor 504 as a power source, and drives the transmission assembly 502 and the passive sprocket assembly 501 to make a rotational motion through the transmission chain 503. At this time, the pull plate claw assembly 6 installed on the transmission chain 503 rotates accordingly with the transmission chain 503. The pull plate claw assembly 6 is composed of the pull plate claw 601 as the main component, and one of the pull plate claws 601 One end is fixed by the plate-pulling claw fixing pin 603, and the other end is a movable end, and the plate-pulling claw positioning pin 602 is used as a limit, so that the plate-pulling claw 601 can make a certain up and down movement around the fixed end due to the downward self-gravity generated by the deflection. At this time, the movement displacement can be adjusted by the diameter difference between the aperture of the movable end and the plate-pulling positioning pin 602 to achieve up and down movement; when the plate-pulling claw 601 is at the bottom, the plate-pulling claw 601 will sag at a certain angle due to gravity, and at this time it is driven by the transmission chain 503. When the plate-pulling claw 601 contacts the positioning block on the filter plate assembly 9, the plate-pulling claw 601 will drive the filter plate assembly 9 to make a horizontal displacement, thereby achieving the purpose of pulling the filter plate apart; when the filter plate assembly 9 moves to the corresponding position, At this time, the bottom of the plate pulling claw 601 will contact the top of the limit block of the previous filter plate assembly 9, causing the plate pulling claw 601 to move upward, thereby separating the plate pulling claw 601 from the filter plate assembly 9, completing a plate pulling movement; multiple plate pulling claw assemblies 6 can be installed on the transmission chain 503 at a certain distance, and as the power shaft of the reduction motor 504 drives the transmission chain 503 to make a circular motion, the plate pulling claw assembly 6 installed on the transmission chain 503 will continuously pull the filter plate assembly 9 to make a horizontal movement, thereby realizing continuous plate pulling and mud cake unloading; after the unloading is completed, the hydraulic station 3 drives the oil cylinder 2 to move forward again, so that the filter plate is pressed in a closed state, and the hydraulic station 3 drives the oil cylinder 2 to move backward and return to the filter plate limit The filter cloth cleaning mechanism 13 is in the initial position, and the hydraulic station 3 is working at this time. The oil cylinder 2 moves forward to the pressure-maintaining state, and the next filtering cycle starts, which improves the filtering efficiency of the filter press equipment. The automatic continuous plate pulling by gravity is adopted, and the structural stability is achieved.
