[0029] See also Figure 1-Figure 7 A high-pressure horizontal press comprises: a pressing frame, which is composed of two square metal frames connected by multiple springs, and the number of springs depends on the required preload; the pressing frame is covered with a filter component, and the filter component is a section of tubular filter cloth connecting two square filter cloths with round holes in the middle. Fixing the filter component to the pressing frame is a pressing unit, and multiple pressing units are arranged on the crossbeam guide rail between the thrust plate and the clamping plate. The pressing power comes from a high-pressure hydraulic cylinder, and the high-pressure hydraulic cylinder is connected to the oil station through an oil pipe.

[0030] A high-pressure horizontal press, comprising:

[0031] The main unit includes two supports 6, a guide rail 7 is installed between the supports 6, a hydraulic cylinder 9 is installed outside one support 6, and a feed port 8 is provided on the other support 6;

[0032] A clamping plate 4, which is connected to the output end of the hydraulic cylinder 9;

[0033] A thrust plate 5, which is installed on the inner side of a support 6 provided with a feed port 8, and is provided with a through hole 22 that docks with the feed port 8;

[0034] The pressing unit 2 is provided with a plurality of pressing units 2 which are installed in parallel between the pressing plate 4 and the thrust plate 5 . An elastic device is provided inside the pressing unit 2 . Ear plates 16 which are slidably connected to the guide rail 7 are provided on both sides of the pressing unit 2 .

[0035] Pressing unit 2 comprises:

[0036] The elastic device is a spring 17, which is installed in a blind hole 20 at the same position of the two squeezing frames 1; the filter component 3, which is a filter cloth of a filter press, is arranged inside the squeezing frame 1 and fixed on the two squeezing frames 1, and a circular hole 21 is opened in the middle of the filter cloth of the filter press, and the circular hole 21 can facilitate the entry of water-containing materials. The squeezing frames 1 are arranged oppositely, and the outer side of the squeezing frames 1 is fixedly connected with an ear plate 16, and the ear plate 16 can directly slide on the upper surface of the guide rail 7. The hydraulic cylinder 9 pushes the clamping plate 4, and indirectly drives the ear plate 16 to slide on the guide rail 7; the squeezing frame 1 is hollowed out, and the filter component 3 is placed in the hollow part, and the periphery of the filter component 3 is fixed on the outer side of the squeezing frame 1, thereby preventing water-containing materials (such as mud) from overflowing from the edge gap. The squeezing frame 1 has multiple blind holes 20 evenly distributed around it, and a spring 17 is arranged inside it, which can automatically separate the squeezing frame 1, facilitate the unfolding of the filter component, and provide convenience for the next injection of water-containing materials.

[0037] There are two guide rails 7 , and the two guide rails 7 are arranged horizontally, corresponding to the arrangement of the ear plates 16 , so as to avoid problems such as deviation of the pressing unit 2 during operation.

[0038] A feed valve 14 and a pressure gauge 15 are installed on the pipeline 18 between the feed port 8 and the squeezing pump 12. The feed valve 14 is arranged close to the squeezing pump 12 to observe the current pressure and feed status at all times.

[0039] A recessed portion 19 is disposed on one side of the pressing plate 4 and the thrust plate 5 . The recessed portions 19 of the pressing plate 4 and the thrust plate 5 are disposed inwardly, and the area of ​​the recessed portion 19 does not exceed the area of ​​the hollow interior of the pressing frame 1 .

[0040] Working process:

[0041] The first stage: start the high-pressure hydraulic cylinder 9 to push the pressing plate 4 to reach the pre-tightening pressure. At this time, the spring 17 of the pressing unit 2 is not deformed. Through the squeezing pump 12 (plunger pump or high-pressure diaphragm pump), the water-containing material (such as mud) is sent to the filter chamber 13 composed of the squeezing units 2 connected in series, and the water will begin to flow out from the gaps in the filter cloth in the filter component 3. With the continuous injection of the water-containing material, the pressure in the filter chamber 13 will gradually increase. When the set pressure is reached (this pressure is less than the pre-tightening force of the hydraulic cylinder 9), the injection is stopped and the feed valve 14 is closed.

[0042] The second stage: start the high-pressure hydraulic cylinder 9 to increase the pressing force. Under the action of the pressing plate 4, the spring 17 of the pressing frame 1 will shrink, and the volume of the filter chamber 13 will be further reduced. Under the action of pressure, the moisture of the water-containing material will further overflow. When a pressure setting value is reached, the pressurization is stopped and maintained for a period of time to allow the moisture to flow out as much as possible; then further pressurization is applied. In order to minimize the moisture content, several cycles of pressurization and pressure maintenance may be required until the requirement is met.

[0043] The third stage: the hydraulic cylinder 9 restores the pressing plate 4 to its initial position. During this process, the spring 17 of the pressing frame 1 is reset, and then the pressing units 2 are separated one by one. During this process, the mud cake in the filter chamber 13 will fall off, and the entire working process is completed.

[0044] The device provides pressure to the pressing unit 2 by starting the hydraulic cylinder 9 twice, which can fully compact the sludge under high pressure, thereby improving the processing efficiency and pressing effect. The high-pressure horizontal press works under high pressure, ensuring a better pressing effect and meeting the needs of some special industries for high-pressure pressing equipment.

[0045] The setting of the elastic device makes it easier to separate the pressing frame 1. The frame separation operation can be completed without manual separation, and the structure is simple.
