Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to an embedded filter cloth for a filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. When a filter press is working, filter cloth is often used to filter its internal components. In the traditional way of installing filter cloth, the filter cloth needs to be laid on the surface of the filter press, and then the sealing strip is hammered into the interior of the filter press. After the filter cloth is passed through on one side, multiple workers are needed to unfold and flatten it. This operation method is quite cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide an embedded filter cloth for a filter press to solve the problems existing in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an embedded filter cloth for a filter press, comprising a filter cloth body, and further comprising:

[0005] A sealing strip surrounding one side of the filter cloth body;

[0006] A connecting ring is fixedly connected to the middle position of the inner side of the filter cloth body. A connecting strip is rotatably connected to one side of the connecting ring, and a tension rope is provided at one end of the front side of the connecting strip.

[0007] A support bar is slidably connected inside the connecting bar. One end of the support bar is fixedly connected to a fixing ring. One end of the tension rope is hung on the surface of the fixing ring. The other end of the support bar is fixedly connected to a fixing post, and one end of the fixing post is fixedly connected to one side of the filter cloth body.

[0008] Preferably, the surface of the connecting strip is provided with a plurality of grooves, and sliders are slidably connected inside the grooves on the upper and lower sides, and the inner side of the sliders is fixed to the surface of the support strip.

[0009] Preferably, the surface of the fixing ring is slidably connected to the groove opened on the front side of the connecting strip.

[0010] Preferably, the connecting strips are arranged in a cross shape on the surface of the connecting ring, and the two connecting strips at the top and bottom and the two connecting strips at the left and right are symmetrically distributed.

[0011] Preferably, the size of the connecting ring is smaller than the size of the water passage in the middle of the filter press.

[0012] Preferably, the length of the filter cloth body after being unfolded and laid flat is adapted to the longest distance of the support strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Before inserting the filter cloth body, this invention allows the filter cloth body to be folded into an umbrella shape and passed through the water passage. As the filter cloth body is compressed, the support bar slides inside the connecting bar, while the tension rope is stretched. After the filter cloth body passes through, the elastic force of the tension rope itself can drive the support bar to slide outward inside the connecting bar, thereby unfolding and laying the filter cloth body flat, reducing the trouble of flattening and facilitating better subsequent installation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8 As shown, an embedded filter cloth for a filter press includes a filter cloth body 1. A sealing strip 2 surrounds one side of the filter cloth body 1. A connecting ring 3 is fixedly connected to the middle position of the inner side of the filter cloth body 1. A connecting strip 4 is rotatably connected to one side of the connecting ring 3. Several sliding grooves 6 are formed on the surface of the connecting strip 4. Sliding blocks 8 are slidably connected inside the upper and lower sliding grooves 6, and the inner side of the sliding blocks 8 is fixed to the surface of the support strip 5. Through the cooperation of the sliding grooves 6 and the sliding blocks 8, the support strip 5 can slide more stably inside the connecting strip 4, preventing it from swaying left and right. A tension rope 9 is provided at one end of the front side of the connecting strip 4. A support strip 5 is slidably connected inside the connecting strip 4. A fixing ring 10 is fixedly connected to one end of the support strip 5, and one end of the tension rope 9 is hung on the surface of the fixing ring 10. The length of the filter cloth body 1 after unfolding and flattening is adapted to the longest distance of the support strip 5. Because the size of the extended support strip 5 is just right to extend the filter cloth body 1, it makes it more convenient to install the sealing strip 2. A fixing post 7 is fixedly connected to the other end of the support strip 5, and one end of the fixing post 7 is fixedly connected to one side of the filter cloth body 1.

[0026] The surface of the fixing ring 10 is slidably connected to the groove 6 opened on the front side of the connecting strip 4. By sliding the fixing ring 10 inside the groove 6, the support strip 5 can be moved left and right.

[0027] The connecting strips 4 are arranged in a cross shape on the surface of the connecting ring 3, and the two connecting strips 4 on the top and bottom and left and right are symmetrically distributed. Because the connecting strips 4 are arranged in a cross shape and symmetrically distributed on the top and bottom and left and right, the filter cloth body 1 can be evenly laid on the surface of the filter press.

[0028] The size of the connecting ring 3 is smaller than the size of the water passage in the middle of the filter press. Because the size of the connecting ring 3 is smaller than the size of the water passage in the middle of the filter press, the connecting ring 3 can easily pass through the water passage, which facilitates the laying of the filter cloth body 1 on both sides of the filter press.

[0029] It is worth noting that the technical features of the filter cloth body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0030] Working principle: When the filter cloth body 1 needs to be laid flat and embedded inside the filter press, first insert the unfurled filter cloth body 1 into the water passage hole in the middle of the filter press, so that one side of the filter cloth body 1 is on the left side of the filter press and the other side is on the right side. At this time, the unfurled filter cloth body 1 can be unfolded in all directions. After unfolding, the tension of the tension rope 9 on the fixing ring 10 will cause the support bar 5 to slide outward. When it slides to the top, by squeezing the connecting ring 3 inward, the filter cloth body 1 can be unfolded on the surface of the filter press, thereby reducing the trouble of manual flattening. Then, the sealing strip 2 can be knocked into the interior of the filter press, thereby completing the fixation of the filter cloth body 1.
