[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] First embodiment:

[0020] See also Figure 1 to Figure 3 ,in, Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a front view of the first embodiment of the utility model. Figure 3 The utility model Figure 2 AA line section view.

[0021] The utility model provides a sludge filter press device, comprising a cylinder 101, a feed port 102, a screw 103, a motor 104, a sliding plate 105, two limit rods 106, two cutting plates 107 and two telescopic components, each of the telescopic components comprising a telescopic rod 108, a spring 109 and a pressing plate 110. The above-mentioned solution solves the problem of low work efficiency caused by the need to remove the loading cylinder and clean the sludge before continuing to use after filtering the sludge.

[0022] According to this specific embodiment, the feed port 102 is fixedly connected to the cylinder 101 and is located above the cylinder 101. The feed port 102 is arranged in a funnel shape. A plurality of round holes 111 are arranged at the bottom of the cylinder 101. Openings 112 are arranged at both ends of the bottom of the cylinder 101. The screw rod 103 is rotatably connected to the cylinder 101 and is located inside the cylinder 101. The motor 104 is fixedly connected to the cylinder 101 and is located on one side of the cylinder 101. The two limit rods 106 are fixedly connected to the cylinder 101. The sliding plate 105 is threadedly connected to the screw rod 103 and is covered on the surfaces of the two limiting rods 106. The two telescopic components are arranged on both sides of the cylinder 101. The sludge is loaded into the cylinder 101 through the feed port 102, and the excess sewage falls through the circular hole 111. The motor 104 drives the screw rod 103 to rotate, and under the restriction of the two limiting rods 106, the sludge is pushed to one side of the cylinder 101 for extrusion. After extrusion, the sludge falls through the opening 112.

[0023] Among them, the telescopic rod 108 is fixedly connected to the cylinder 101 and is coated on the outside of the screw rod 103 and the limit rod 106. The pressing plate 110 is fixedly connected to the telescopic rod 108 and is coated on the surface of the limit rod 106 and the screw rod 103. The spring 109 is coated on the surface of the telescopic rod 108. The telescopic rod 108 pushes the pressing plate 110 to block one side of the opening 112. When squeezing the sludge, the telescopic rod 108 and the spring 109 contract. After squeezing, the sludge falls through the opening 112. The spring 109 pushes the pressing plate 110 to move to its original position. The pressing plate 110 is adapted to the cylinder 101 so that the spring 109 cannot quickly push the pressing plate 110 back to its original position to prevent the sludge from falling completely. The pressing plate 110 moves to one side of the opening 112.

[0024] Secondly, the two cutting plates 107 are fixedly connected to the pressing plate 110 and are located on one side of the pressing plate 110. The surface of the sliding plate 105 is provided with a groove 113, and the groove 113 is adapted to the cutting plate 107. When squeezing the sludge, the cutting plate 107 cuts the sludge into pieces to prevent large pieces of sludge from blocking the opening 112.

[0025] When using the utility model, sludge is loaded into the cylinder 101 through the feed port 102, and excess sewage falls through the circular hole 111. The motor 104 drives the screw rod 103 to rotate, and under the restriction of the two limit rods 106, the sludge is pushed to one side of the telescopic rod 108, the telescopic rod 108 and the spring 109 contract, and the cutting plate 107 cuts the sludge to prevent large pieces of sludge from blocking the opening 112. After squeezing, the sludge falls through the opening 112, and the spring 109 pushes the pressing plate 110 to move to its original position.

[0026] Second embodiment:

[0027] See also Figure 4 , Figure 4 It is an overall structural sectional view of the second embodiment of the utility model.

[0028] On the basis of the first embodiment, the utility model provides a sludge filter press device, which also includes a separation component, wherein the separation component includes a box body 201 and two collecting boxes 202. Through the arrangement of the above structure, sewage and sludge are collected separately for easy treatment.

[0029] According to this specific embodiment, the separation component is arranged below the cylinder 101 , and the sewage and the sludge fall through the opening 112 and the round block respectively, and then fall into the separation component respectively, and are collected separately.

[0030] The box body 201 is fixedly connected to the cylinder 101 and is located below the box body 201. The two collecting boxes 202 are slidably connected to the box body 201 and are located below the corresponding openings 112. A plurality of through holes 203 are provided at the bottom of the collecting box 202. During extrusion, the sewage in the sludge falls into the box body 201 through the openings 112. During extrusion, the squeezed sewage falls into the box body 201 through the through holes 203. After extrusion is completed, the sludge falls into the collecting box 202 through the openings 112.

[0031] When using the utility model, the sludge is loaded into the cylinder 101 through the feed port 102, and the excess sewage falls into the box body 201 through the circular hole 111. The motor 104 drives the screw rod 103 to rotate, and under the restriction of the two limit rods 106, the sludge is pushed to one side of the telescopic rod 108, the telescopic rod 108 and the spring 109 contract, and the cutting plate 107 cuts the sludge to prevent large pieces of sludge from blocking the opening 112. After squeezing, the sludge falls into the collecting box 202 through the opening 112, and the collecting box 202 is replaced. The spring 109 pushes the pressing plate 110 to move to its original position, and the motor 104 drives the screw rod 103 to rotate in the opposite direction, so that the subsequent sludge is pushed to the pressing plate 110 on the other side to repeatedly filter the sludge, thereby improving the practicality of the utility model.
