At present, the mud and water separation of slurry generally adopts a filter press, which includes a pressing mechanism and a filtering mechanism. The filtering mechanism is composed of a filter press 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 existing filter press mud and water separation mechanism has a complex structure and high manufacturing cost, especially the design of the filter press plate is complex, the filter cloth is easy to clog, the filter press efficiency is not high, and the maintenance and replacement is time-consuming and labor-intensive. Summary of the invention

[0018] 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.

[0019] like Figure 1 , Figure 2 and Figure 3 The present invention provides a mud-water separation structure for tile slurry, which comprises a separation end plate 10 arranged at both ends and a plurality of separation middle plates 11 which can be pressed between the two separation end plates. The two separation end plates are respectively pressed with the corresponding separation middle plates and between two adjacent separation middle plates to form a separation chamber 12 which can accommodate and separate the tile slurry. During the implementation process, the separation end plate at the rear end is kept fixed, and the separation end plate at the front end is hydraulically driven to move to realize the pressing or loosening of the separation end plate and the separation middle plate; each separation chamber 12 is connected to a feed channel 13, and each separation end plate and each separation middle plate are provided with a water passage 14. The tile slurry flowing into each separation chamber from the feed channel is separated from mud and water under the action of pumping pressure, and the separated water flows out from the corresponding water passage, and the separated mud is pressed in the corresponding separation chamber to form a 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 automatically without manual treatment, thereby improving the filter pressing efficiency.

[0020] Specifically, each separation chamber 12 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 screen to form the separation chamber, 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 not only makes it convenient and fast to repair and replace the filter screen, saves time and effort, but also the open filter screen is not easy to cause mud clogging, which can further improve the filter pressing efficiency.

[0021] Preferably, a filter chamber 123 is formed between the filter screen 122 and the corresponding half chamber, and the tile slurry flowing into the separation chamber from the feed channel is separated from the mud and water by the filter screen, and the separated water flows into the corresponding filter chamber and then flows out from the corresponding water passage. The filter chamber of the present invention provides sufficient space for mud and water separation, which is conducive to the rapid discharge of water. The feed channel 13 includes a front section 131 horizontally arranged in the middle of the separation end plate at the front end and passing through the corresponding filter screen, and a rear section 132 arranged in the middle of each separation middle plate and passing through the corresponding filter screen. 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 by the front section of the feed channel, the next separation chamber is filled in turn by 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 and 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 not only facilitates 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.

[0022] During implementation, each of the water passages 14 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. The lower end of each vertical channel is connected to the corresponding outlet. 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, and then flows out through the upper end of the vertical channel. This design of drainage from bottom to top can reduce the mud content in the water and improve the utilization rate of the mud. Preferably, a transverse channel 143 is horizontally provided on the upper part of each separation end plate and each separation middle plate. The upper end of each vertical channel is connected to the middle part of the corresponding transverse channel to divert the water in the transverse channel and improve the water outlet efficiency; the water flowing from the vertical channel into the corresponding transverse channel flows out through the water outlet channel 15, thereby directing the water to the upper part of the separation structure, providing space for the mud cake to automatically fall downward, and making the layout of the entire separation structure simpler and more reasonable.

[0023] The water outlet channel 15 of the present invention includes two axial through holes arranged on both sides of the upper part along the thickness direction of the front separation end plate or each separation middle plate and two blind holes axially opened on both sides of the upper part of the rear separation end plate. The two blind holes or two axial through holes are respectively connected to the two ends of the corresponding transverse channel, and the water diverted through the transverse channel is discharged from the blind holes or axial through holes at both ends and then collected. Specifically, when the two separation end plates and several separation middle plates are pressed, the two blind holes and the two axial through holes of each separation middle plate form a continuous double-channel one-way water outlet channel. Since the rear separation end plate 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 front separation end plate under pressure, and then flow out through the water outlets of the two axial through holes of the front separation end plate, and the two water outlets can be connected through an external water pipe and then discharged in a centralized manner.

[0024] 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. Therefore, 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.
