The existing plate press generally includes a pressing mechanism and a filtering mechanism. The filtering mechanism is composed of a filter plate and a filter cloth. The slurry in the filter mechanism is pressed by a hydraulic pressing mechanism, so that the water in the slurry is precipitated through the filter cloth to form a mud cake to obtain the blank. However, the mud cake obtained by this type of filter press needs to be carried manually or by machine, which increases the cost. In addition, the structure of the mud and water separation mechanism of this type of filter press is relatively complex and the manufacturing cost is high, especially the design of the filter plate is complex, the filter cloth is easily blocked, the filter pressing efficiency is not high, and the maintenance and replacement is time-consuming and labor-intensive.

As the shift car moves backward, the other end of one of the shift blocks abuts against one side wall of the cross bar, and then the shift car moves forward, and the other end of the other shift block abuts against the other side wall of the cross bar. As the shift car continues to move forward, the other end of the other shift block pushes the corresponding separation middle plate forward through the cross bar.

[0020] The present invention is described in detail below in conjunction with the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a plate press for processing ceramic tiles, which includes a frame 2, a mud-water separation structure 1 arranged on the frame, and a driving mechanism 3. After the mud-water separation structure 1 is pressed on the frame 2 by the driving mechanism, the tile slurry is pumped to the mud-water separation structure through the feeding mechanism 4 for mud-water separation. The separated water is discharged through the drainage mechanism 5 arranged at the upper part of the frame, and the separated mud is compressed to form a mud cake; after the driving mechanism releases pressure to release the mud-water separation structure, the mud cake automatically falls from the mud-water separation structure into the collecting tank 6 arranged at the lower part of the frame. It can be seen that the present invention obtains the mud cake by pressing and pumping pressure, and the mud cake can be automatically dropped after the pressure is released, without manual or machine handling, saving labor and cost. At the same time, the present invention collects mud cakes at the lower part of the frame and drains water at the upper part. It has a compact structure and occupies a small area, which can further save costs.

[0022] The frame 2 of the present invention is provided with rails 21 on both sides, and a fixed pressure plate 22 is fixedly provided at one end of the rail. The driving mechanism 3 includes a driving cylinder 31 arranged on the frame and a dynamic pressure plate 32 arranged at the other end of the rail. The driving cylinder pushes the dynamic pressure plate to move along the rail to press the mud-water separation structure between the dynamic pressure plate and the fixed pressure plate, that is, the fixed pressure plate remains fixed and pushes the dynamic pressure plate to compress the mud-water separation structure to keep it in a compact state, so as to subsequently transport the slurry into the mud-water separation structure. When the slurry is continuously transported to the mud-water separation structure by the delivery pump, the water contained in the slurry is removed, and the mud is continuously gathered and squeezed to form a mud cake, and then the slurry delivery is stopped, and the driving cylinder is started again, which releases the pressure by pulling the dynamic pressure plate to move along the rail to release the mud-water separation structure, so that the mud cake can fall automatically.

[0023] Specifically, the mud-water separation structure 1 includes a separation end plate 10 connected to the fixed pressure plate 22 and the dynamic pressure plate 32 respectively, and a plurality of separation middle plates 11 that can be pressed between the two separation end plates, wherein the fixed pressure plate is fixedly connected to the separation end plate at the rear end, and the dynamic pressure plate is fixedly connected to the separation end plate at the front end, so that the dynamic pressure plate driven by the driving cylinder drives the separation end plate at the front end to move and can press or loosen the mud-water separation structure; a separation chamber 12 that can accommodate and separate tile slurry is formed by pressing between the two separation end plates and the corresponding separation middle plates and between two adjacent separation middle plates, each separation chamber 12 is connected to the feeding mechanism 4, and each separation end plate and each separation middle plate are provided with a water passage 14, and the tile slurry flowing into each separation chamber from the feeding mechanism 4 is separated from mud and water under the action of pumping pressure, and the separated water flows into the drainage mechanism 5 from the corresponding water passage, and the separated mud is pressed in the corresponding separation chamber to form the mud cake. Therefore, when the separation end plate and the separation middle plate are depressurized and loosened, the separation chamber is separated and the mud cake falls off automatically without manual or machine processing.

[0024] Preferably, the frame 2 is provided with a plate-shifting mechanism 7, which includes auxiliary rails 71 respectively arranged on the outside of the two tracks, a shifting car 8 respectively arranged on each auxiliary rail, and a shifting frame 9 respectively arranged on both sides of each separation middle plate. After the driving mechanism releases pressure to loosen the mud-water separation structure, the two shifting cars 8 shift the corresponding two shifting frames along the track to drive the corresponding separation middle plate to move so that the mud cake in each separation chamber automatically falls into the collection tank. The present invention adopts two auxiliary rails corresponding to two shifting cars, and then the two shifting cars correspondingly shift the two shifting frames to shift the separation middle plate from both sides, which can ensure the smooth movement of the separation middle plate on the basis of ensuring the separation of the separation chamber.

[0025] Specifically, each of the shifting vehicles 8 includes a frame 81 that can move along the corresponding auxiliary rail and a shifting seat 82 arranged on the frame, and arc-shaped shifting blocks 83 are respectively arranged at both ends of the shifting seat along the moving direction of the shifting vehicle. One end of each shifting block is hinged on the shifting seat, and the other end is connected to the shifting seat through a spring 84, and a gap is left between the other ends of the two shifting blocks; each of the shifting frames 9 includes a vertical rod 91 fixedly connected to the side wall of the corresponding separation middle plate, a horizontal rod 92 vertically connected to the vertical rod, and an oblique rod 93 connecting the horizontal rod and the vertical rod to ensure the stability of the shifting frame; the inner end of the horizontal rod contacts the corresponding track through a rubber pad 94 arranged on its bottom wall, and the outer end of the horizontal rod corresponds to the other end of the shifting block. The setting of the rubber pad can reduce the friction between the shifting frame and the track when it moves, thereby increasing the service life of the shifting frame. During the implementation process, the specific correspondence between the outer end of the cross bar and the other end of the shift block is: when the driving mechanism releases pressure to loosen the mud-water separation structure, the shift cart moves to the lower side of the corresponding shift frame, and the cross bar is located in the gap between the two shift blocks. As the shift cart moves backward, the other end of one of the shift blocks rests on one side wall of the cross bar, and then the shift cart moves forward, and the other end of the other shift block rests on the other side wall of the cross bar. As the shift cart continues to move forward, the other end of the other shift block pushes the corresponding separation middle plate forward through the cross bar. This reciprocating process can push each separation middle plate forward, thereby separating each separation chamber so that all mud cakes fall off automatically.

[0026] As can be seen from the above, after the plate press of the present invention completes the filtration of the mud cake, it stops conveying the tile slurry, and then drives the cylinder to drive the dynamic pressure plate and the front separation end plate to move forward, so that a gap appears between the front separation end plate and the first separation middle plate, and the corresponding separation chamber is separated, and the mud cake automatically falls. At the same time, the pusher moves backward from the initial position at the front end of the auxiliary rail to the front separation end plate. Preferably, starting frames 95 are provided on both sides of the front separation end plate, and each starting frame is provided with an arc guide plate 96. When the pusher moves to the starting frame, the arc guide plate presses down the other end of one of the pusher blocks. During implementation, when the pusher moves backward, the other pusher block first contacts the arc guide plate due to its arc-shaped structure and is pressed down by the action of the spring, so that it can pass through the starting frame and the pusher frame of the first separation middle plate in turn. During this process, since one of the shift blocks is also arc-shaped, when it moves backward to contact the arc-shaped guide plate, due to the existence of the arc and the compression of the spring sheet, the other end of one of the shift blocks rotates around its hinged end and is pressed down; as the shift cart continues to move backward, the arc-shaped guide plate guides one of the depressed shift blocks to the first separation middle plate, and the other end thereof gradually rises under the action of the elastic force of the spring sheet due to the loss of the pressure of the arc-shaped guide plate until it rests on one side wall of the cross bar of the first separation middle plate, at which time the shift cart stops moving backward, and the shift frame of the first separation middle plate is located in the gap between the two shift blocks.

[0027] Next, the trolley starts to move forward through hydraulic or pneumatic control, and the lower end of one of the trolley blocks gradually contacts the arc guide plate, while the other end of the other trolley block gradually rises as it moves forward until it abuts against the other side wall of the crossbar of the first separation middle plate; as the trolley continues to move forward, the other trolley block pushes the first separation middle plate forward until it moves to contact the separation end plate at the front end, and then the trolley stops moving. At the same time, one of the trolley blocks will first be pressed down by the starting frame, and as it continues to move backward, one of the trolley blocks will be pressed down on the lower side of the first separation middle plate. Then the trolley moves backward, driving the other end of one of the trolley blocks to abut against one side of the crossbar of the second separation middle plate, and then the trolley moves forward and drives the second separation middle plate forward through another trolley block, and so on and so forth, until the last separation middle plate moves forward, thereby separating the separation chamber of the separation end plate at the rear end, and achieving the automatic falling of all mud cakes. Preferably, a pin seat 85 is provided on the shift seat 82 at the outer side of one end of the other shift block, and a latch 86 is provided on the pin seat along the moving direction of the shift car. After the latch is inserted into the pin seat, it can extend from one end of the other shift block to the other end of the other shift block to press down the other end. After the shift car shifts the last separation middle plate forward, the shift car cannot continue to move forward to the initial position because the other section of the other shift block abuts against the side of the cross bar. Therefore, the present invention designs a latch, which can press down the other end of the other shift block to the lower side of the cross bar, so that the shift car can move through the lower side of all shift racks to the initial position after completing the shifting of all separation middle plates, so that the equipment can perform the next filter pressing.

[0028] Each separation chamber 12 of the present invention includes a concave half chamber 121 arranged on the inner side of each separation end plate or on both sides of each separation middle plate, and each half chamber is provided with a filter screen 122 for filtering slurry. Two adjacent half chambers are formed by pressing the filter screens, so that the tile slurry in the separation chamber can be covered in two pressed filter screens, thereby continuing to pump the slurry to pressurize the mud and water to obtain a mud cake. The present invention designs the separation chamber into two separable half chambers, which is not only convenient and fast to repair and replace the filter screen, saving time and effort, but also the open filter screen is not easy to cause mud clogging, which can further improve the filter pressing efficiency. A filter cavity 123 is formed between the filter screen 122 and the corresponding half chamber, and the tile slurry flowing into the separation chamber from the feeding mechanism 4 is separated from the mud and water by the filter screen, and the separated water flows into the corresponding filter cavity, and then flows into the drainage mechanism 5 from the corresponding water passage 14. The filter cavity of the present invention provides sufficient space for mud and water separation, which is conducive to the rapid discharge of water.

[0029] Preferably, the feeding mechanism 4 includes a feeding channel 13 and a feeding pipe 41 which passes through a hollow telescopic rod of the driving cylinder and is installed on the dynamic pressure plate, and an external delivery pump delivers the tile slurry to the feeding channel through the feeding pipe. In the implementation process, the feeding pipe adopts a hose, so that when the driving cylinder drives the dynamic pressure plate to move, the feeding pipe can move with it to ensure the operation of the equipment. The feed channel 13 includes a front section 131 which is horizontally arranged in the middle of the separation end plate at the front end and passes through the corresponding filter screen, and a rear section 132 which is arranged in the middle of each separation middle plate and passes through the corresponding filter screen. The front section is connected to the feed pipe 41, and the front section and the rear section are respectively connected to the corresponding separation chamber, that is, the entire feed channel is discontinuous, so that all the separation chambers can be filled, that is, after the first separation chamber is filled through the front section of the feed channel, the next separation chamber is filled in sequence through the rear section of the feed channel until the last separation chamber is filled with slurry. The separation end plate at the rear end of the last separation chamber is not provided with a feed channel, so that the entire feed channel forms a one-way closed channel, so that the mud-water separation is realized by continuously pumping the slurry and continuously pressurizing. Each section of the feed channel of the present invention passes through the middle of the corresponding filter screen and extends into the separation chamber, which is not only convenient for feeding, but also can tightly connect the middle of the filter screen to the feed channel, ensuring that the filter screen is installed more securely.

[0030] Each of the water passages 14 of the present invention includes an outlet 141 connected to the corresponding filter chamber and a vertical channel 142 vertically arranged in each separation end plate or each separation middle plate. A transverse channel 143 is horizontally arranged on the upper part of each separation end plate and each separation middle plate. The lower end of each vertical channel is connected to the corresponding outlet, and the upper end is connected to the middle part of the corresponding transverse channel, so as to divert the water in the transverse channel and improve the water discharge efficiency. The water filtered by the filter in the separation chamber flows into the filter chamber, then flows into the corresponding vertical channel through the outlet, then flows into the corresponding transverse channel through the upper end of the vertical channel, and then is discharged from the drainage mechanism 5, thereby directing the water to the upper part of the separation structure, providing space for the mud cake to automatically fall downward, making the layout of the entire separation structure simpler and more reasonable; and this design of drainage from bottom to top can reduce the mud content in the water and improve the utilization rate of the mud.

[0031] The drainage mechanism 5 includes two drainage pipes 51 installed on the upper part of the fixed pressure plate, two axial through holes 15 arranged on both sides of the upper part along the thickness direction of the separation end plate at the rear end or each separation middle plate, and two blind holes axially opened on both sides of the upper part of the separation end plate at the front end. The two blind holes or two axial through holes are respectively connected to the two ends of the corresponding transverse channel. The two axial through holes of the separation end plate at the rear end are both connected to the drainage pipe. The water flowing into the two drainage pipes from the two axial through holes can be collected centrally by the drainage main pipe. In the present invention, when the two separation end plates and several separation middle plates are pressed tightly, the two blind holes and the two axial through holes of the separation end plate at the rear end and each separation middle plate form a continuous double-channel one-way water outlet channel. The water in each transverse channel flows into the blind hole or axial through hole and then flows into the drainage pipe 51 along the water outlet channel to be discharged. Since the separation end plate at the front end is provided with a blind hole, the water flowing into the blind hole or axial through hole from both ends of the transverse channel can only flow out in the direction of the axial through hole of the separation end plate at the rear end under the action of pressure, and then flows into the two drainage pipes to be discharged. As can be seen from the above, the plate press of the present invention is provided with a feed at the front end and a water outlet at the rear end, and its layout is more reasonable and the structure is compact, which can further save space.

[0032] During implementation, each filter screen of the present invention covers the entire corresponding half chamber and is connected to the periphery of the corresponding separation end plate or separation middle plate by screws, so that on the one hand, the filter screen can completely cover the separation chamber, prevent slurry leakage after compression, and improve the mud-water separation effect; on the other hand, the filter screen can be quickly replaced by simply loosening the screws to improve the separation efficiency. Preferably, a plurality of bosses 124 are horizontally arranged in each half chamber, and each boss rests on the corresponding filter screen. On the one hand, the cooperation between the boss and the feed channel can more stably install and support the filter screen. On the other hand, under the action of the pumping pressure, the boss can reversely squeeze the slurry in the separation chamber, which can not only reduce the water content of the mud cake, but also promote faster separation of mud and water.
