Technical Field

[0001] This utility model relates to the field of plate and frame filter press technology, and in particular to a mud receiving hopper for a plate and frame filter press. Background Technology

[0002] Plate and frame filter presses were the first machines used for chemical dewatering, and the sludge hopper of a plate and frame filter press is used to store and transport the dewatered sludge cake.

[0003] A sludge receiving hopper for an existing plate and frame filter press can be found in Chinese Utility Model Patent Publication No. CN215387796U, which discloses a plate and frame filter press including a base. Supports are fixed to both sides of the upper end of the base. The filter press body is fixed to the upper end of the supports. Filter plates are installed on the filter press body. A sludge cake collecting assembly is fixed to the supports and is located directly below the filter press body. The sludge cake collecting assembly consists of a collecting hopper, a crushing chamber, and an output chamber. A crushing roller is rotatably installed inside the crushing chamber. An output pipe is fixed to the side wall of the output chamber. A spiral conveying roller is rotatably installed inside the output pipe. The spiral conveying roller and the crushing roller are connected by a transmission mechanism.

[0004] However, during actual use, it was found that although the device can achieve integrated functions of collecting, crushing, and outputting mud cakes, making it easier to process and recycle them, the mud cakes have a high density and weight. As a result, when the mud cakes fall into the mud receiving hopper, they will affect the shell of the hopper. Over time, this will cause damage to the mud receiving hopper and affect the normal use of the device. Therefore, this application provides a mud receiving hopper for a plate and frame filter press to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mud receiving hopper for a plate and frame filter press to solve the limitation of existing mud cakes, which have high density and heavy weight. As a result, when the mud cake falls into the mud receiving hopper, it will affect the shell of the mud receiving hopper, and eventually cause damage to the mud receiving hopper, thus affecting the normal use of the device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a filter press body, and a buffer assembly and a crushing assembly installed on the filter press body; a fixed frame is fixedly mounted at the bottom of the filter press body; the buffer assembly includes a fixed rod installed on the inner wall of the fixed frame, a sleeve is fixedly mounted at the bottom of the fixed rod, a damping block is slidably connected to the inner wall of the sleeve, a moving rod is fixedly mounted at the bottom of the damping block, a connecting rod is fixedly mounted at the bottom of the moving rod, a spring is fixedly mounted at the bottom of the fixed rod, the bottom of the spring is fixedly connected to the top of the connecting rod, a locking pin is fixedly mounted at the bottom of the connecting rod, a positioning rod is engaged with the outer wall of the locking pin, a fixing bolt is threadedly connected to the outer wall of the positioning rod, the fixing bolt passes through the positioning rod and is threadedly connected to the locking pin, and a mud receiving hopper body is fixedly mounted on the side of the positioning rod away from the fixed frame.

[0007] Preferably, the crushing assembly includes a fixed frame installed at the bottom of the mud receiving hopper body, a rotating shaft rotatably connected to the fixed frame, a crushing roller 1 fixedly mounted at one end of the rotating shaft, a gear 1 fixedly mounted at the other end of the rotating shaft, a transmission belt meshing with the outer wall of the gear 1, a gear 2 meshing with the side of the transmission belt away from the gear 1, a rotating rod fixedly mounted with the inner wall of the gear 2, a crushing roller 2 fixedly mounted with the outer wall of the rotating rod, a motor fixedly mounted with the end of the gear 1 away from the rotating shaft, and a baffle slidably connected to the bottom of the fixed frame.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, the sludge cake generated during operation is discharged from the filter press body and falls into the sludge receiving hopper body. After the sludge cake contacts the sludge receiving hopper body, the sludge receiving hopper body moves downward, thereby driving the spring to stretch. At the same time, the sludge receiving hopper body drives the positioning rod and the moving rod to move downward, thereby driving the damping block to slide in the sleeve, increasing its friction. At this time, the spring also rebounds, which helps to weaken the impact force of the sludge cake and reduce the impact force of the sludge cake on the sludge receiving hopper body. Ultimately, the sludge cake is buffered, reducing the damage to the sludge receiving hopper body. After the operation is completed, the sludge receiving hopper body can be disassembled by fixing bolts for cleaning and maintenance, improving the service life of the sludge receiving hopper body.

[0015] 2. In the above scheme, the motor drives gear one to rotate, which in turn drives the transmission belt and gear two to rotate. The rotation of gear one and gear two drives the rotating shaft and rotating rod to rotate, which in turn drives crushing roller one and crushing roller two to rotate. This can crush the mud cake that falls into the mud receiving hopper, making it easier to collect and transport the mud cake. Attached Figure Description

[0029] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of this utility model provides a sludge receiving hopper for a plate and frame filter press, comprising: a filter press body 1, and a buffer assembly 2 and a crushing assembly 3 installed on the filter press body 1; a fixing frame 101 is fixedly mounted on the bottom of the filter press body 1; the buffer assembly 2 includes a fixing rod 201 installed on the inner wall of the fixing frame 101, a sleeve 202 fixedly mounted on the bottom of the fixing rod 201, a damping block 203 slidably connected to the inner wall of the sleeve 202, a moving rod 204 fixedly mounted on the bottom of the damping block 203, a connecting rod 205 fixedly mounted on the bottom of the moving rod 204, a spring 206 providing elastic force fixedly mounted on the bottom of the fixing rod 201, the bottom of the spring 206 being fixedly connected to the top of the connecting rod 205, and the bottom of the connecting rod 205 being fixedly mounted. The device is equipped with a locking pin 207, and a positioning rod 208 is engaged with the outer wall of the locking pin 207. A fixing bolt 209 is threadedly connected to the outer wall of the positioning rod 208. The fixing bolt 209 passes through the positioning rod 208 and is threadedly connected to the locking pin 207. A mud receiving hopper body 210 is fixedly assembled on the side of the positioning rod 208 away from the fixing frame 101. There are two sets of sleeves 202, damping blocks 203, moving rods 204 and springs 206, and the two sets of sleeves 202, damping blocks 203, moving rods 204 and springs 206 are symmetrically distributed on both sides of the positioning rod 208. By limiting the number and position of sleeves 202, damping blocks 203, moving rods 204 and springs 206, it is beneficial to improve the buffering effect on mud cake and weaken the impact force on the mud receiving hopper body 210.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the crushing assembly 3 includes a fixed frame 301 installed at the bottom of the sludge receiving hopper body 210. A rotating shaft 302 is rotatably connected to the fixed frame 301. A crushing roller 303 is fixedly mounted at one end of the rotating shaft 302, and a gear 304 is fixedly mounted at the other end of the rotating shaft 302. A transmission belt 305 meshes with the outer wall of the gear 304. A gear 306 meshes with the side of the transmission belt 305 away from the gear 304. A rotating rod 307 is fixedly mounted on the inner wall of the gear 306, and a crushing roller 307 is fixedly mounted on the outer wall of the rotating rod 307. A motor 308 is fixedly mounted on the end of 304 away from the rotating shaft 302. A baffle 309 is slidably connected to the bottom of the fixed frame 301. The motor 308 drives the gear 1 304 to rotate. The rotation of the gear 1 304 drives the transmission belt 305 and the gear 2 306 to rotate. The rotation of the gear 1 304 and the gear 2 306 drives the rotating shaft 302 and the rotating rod 307 to rotate, which in turn drives the crushing roller 1 303 and the crushing roller 2 to rotate. This enables the crushing of mud cakes that fall into the mud receiving hopper body 210, facilitating the collection and transportation of mud cakes.

[0031] like Figure 2 and Figure 4As shown, a bellows 211 is fixedly mounted on the bottom of the fixing rod 201. The bottom of the bellows 211 is fixedly connected to the top of the positioning rod 208. The spring 206 is located inside the bellows 211. By setting the bellows 211, it is beneficial to protect the spring 206 through the bellows 211, thereby reducing the corrosion of the spring 206 and improving the service life of the spring 206.

[0032] like Figure 3 and Figure 6 As shown, a limiting groove 212 is provided on the side of the fixed frame 101 near the positioning rod 208. A sliding rod 213 is fixedly assembled at the end of the positioning rod 208, and the sliding rod 213 is a "T" shaped rod. By setting the limiting groove 212 and the sliding rod 213, it is beneficial to limit the movement of the positioning rod 208, thereby improving the stability of the positioning rod 208 and the mud receiving hopper body 210 when they move.

[0033] like Figure 3 and Figure 6 As shown, grooves 214 are provided on both sides of the slide bar 213. A pulley 215 is rotatably connected to the inner wall of the groove 214. The outer wall of the pulley 215 is rolledly connected to the inner wall of the limiting groove 212. By setting the grooves 214 and the pulley 215, it is beneficial to improve the smoothness of the slide bar 213 when it moves in the limiting groove 212 and reduce the problem of jamming.

[0034] like Figure 2 and Figure 4 As shown, the cross-sectional shape of the locking pin 207 is "n" shaped, and the inner wall of the positioning rod 208 is adapted to the shape of the locking pin 207. By limiting the locking pin 207, it is beneficial to cooperate with the fixing bolt 209 to improve the firmness and reliability of the connection between the connecting rod 205 and the positioning rod 208.

[0035] The technical solution provided by this utility model, during operation, discharges the mud cake generated during the operation through the filter press body 1 and drops it into the mud receiving hopper body 210. After the mud cake contacts the mud receiving hopper body 210, the mud receiving hopper body 210 moves downward, thereby driving the spring 206 to stretch. At the same time, the mud receiving hopper body 210 drives the positioning rod 208 and the moving rod 204 to move downward, thereby driving the damping block 203 to slide in the sleeve 202, increasing its friction. At this time, the spring 206 also rebounds, which helps to weaken the impact force of the mud cake and reduce the impact force of the mud cake on the mud receiving hopper body 210. Ultimately, the mud cake is buffered, reducing damage to the mud receiving hopper body 210. After the operation is completed, the mud receiving hopper body 210 can be disassembled through the fixing bolts 209 for cleaning and maintenance, improving the service life of the mud receiving hopper body 210.

[0036] The motor 308 drives the gear 304 to rotate, which in turn drives the transmission belt 305 and the gear 306 to rotate. The rotation of the gear 304 and the gear 306 drives the rotating shaft 302 and the rotating rod 307 to rotate, which in turn drives the crushing roller 303 and the crushing roller 2 to rotate. This allows the mud cake that falls into the mud receiving hopper body 210 to be crushed, which facilitates the collection and transportation of the mud cake.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
