Description

Technical Field

[0001] This utility model belongs to the technical field of sludge dewatering machines, and in particular relates to a sludge dewatering machine that facilitates sludge removal. Background Technology

[0002] Sludge produced from wastewater treatment has a high water content. Due to the characteristics of water binding with sludge particles, mechanical removal methods have certain limitations. The organic matter content, ash ratio, and especially the amount of flocculant added in the sludge have a significant impact on the final solids content. Generally speaking, mechanical dewatering can achieve a solids content of 20%-30%, and the resulting sludge is also known as sludge cake.

[0003] According to a public announcement, a sludge dewatering machine (CN 215209102 U) includes a flocculation box body, a base, a dewatering tank and a sludge trolley. The top of the flocculation box body is provided with a sludge inlet, and a dosing pipe is provided on one side of the flocculation box body.

[0004] However, in the above design, the flocculation box body, base and other components work together to make it difficult to push the material flowing out of the discharge trough out by the push plate, and the slag removal effect cannot be achieved, which needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a sludge dewatering machine that facilitates sludge removal. Through the cooperation of components such as the outer shell, fixed plate, reciprocating screw, and push plate, when the sludge is dewatered by the machine and flows out of the discharge trough into the inner shell through the discharge pipe, the push plate pushes the material flowing out of the discharge trough out, and the cycle repeats, achieving the effect of sludge removal. This prevents the material from accumulating inside the outer shell, saves the working time of the staff, and solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sludge dewatering machine with easy sludge removal, comprising a base and a flocculation box. The flocculation box is fixedly connected to the inner wall of the base, and a discharge pipe is fixedly inserted through the front side of the flocculation box. An operation panel is fixedly connected to the front side of the base, and a support frame is fixedly connected to the bottom of the operation panel. A sludge removal device is provided on the side of the operation panel. The sludge removal device includes a shell, and a fixing plate is fixedly connected to the inner wall of the shell. A motor is provided on the side of the fixing plate, and a reciprocating lead screw is fixedly connected to the end of the output shaft of the motor. A reciprocating threaded sleeve is fixedly connected to the circumferential surface of the reciprocating lead screw, and a push rod is fixedly connected to the circumferential surface of the reciprocating threaded sleeve. A push plate is fixedly connected to the bottom of the push rod.

[0008] Furthermore, a brush is fixedly connected to the bottom of the push plate, and a discharge groove is provided on the inner wall of the outer shell. This design is beneficial because when the push plate is subjected to force and makes a reciprocating horizontal linear motion, the push plate can drive the brush to make a reciprocating horizontal linear motion.

[0009] Furthermore, there are two discharge troughs, which are circular and interconnected with the discharge pipe. This design allows the material to pass through the discharge troughs into the outer shell when it flows out of the discharge pipe.

[0010] Furthermore, an auxiliary device is provided inside the outer shell. The auxiliary device includes a rectangular groove, which is formed on the inner wall of the outer shell. A filter plate is fixedly connected to the inner wall of the rectangular groove. A filter hole is passed through the top of the filter plate. A water storage tank is fixedly connected to the bottom of the outer shell. This design is beneficial because when materials enter the inner shell, the filter plate can further filter the materials and prevent residual moisture in the materials.

[0011] Furthermore, a ramp is fixedly connected to the side of the outer shell, and a limit block is fixedly connected to the top of the ramp. This design is beneficial for pushing the material onto the ramp surface when the push plate moves, so that the material can slide out using the ramp surface.

[0012] Furthermore, there are two limiting blocks, which are symmetrical to each other along the vertical central axis at the top of the inclined plate. This design is beneficial because when the material is displaced by force to the inclined surface of the inclined plate, the limiting blocks can limit the material and prevent it from falling from both sides of the inclined plate.

[0013] Furthermore, the angle between the inclined plate and the outer shell is less than 90 degrees, the rectangular groove runs through the bottom of the water storage tank, and the push plate is slidably connected to the inner wall of the outer shell. This design is beneficial because when the filter plate filters the material, the filtered water can flow into the water storage tank through the rectangular groove.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through the cooperation of components such as the outer shell, fixing plate, reciprocating screw, and push plate, achieves the following: when the sludge is dewatered by the machine and flows out of the discharge trough into the inner shell through the discharge pipe, the push plate pushes the material flowing out of the discharge trough out, and the cycle repeats, thus achieving the effect of slag removal and preventing the material from accumulating inside the outer shell, saving the workers' time.

[0016] This utility model utilizes components such as a rectangular trough, a filter plate, filter holes, and a water storage tank to work together to allow materials to slide down the inclined plane under the influence of gravity. To prevent materials from falling from the sides of the inclined plane, a limiting block fixed to the top of the inclined plane can limit their movement, preventing materials from falling from the sides. Workers can collect the sliding materials, which not only assists the slag removal device but also improves the work efficiency of the workers.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model is a sludge dewatering machine with easy sludge removal, including a base 1 and a flocculation box 2. The flocculation box 2 is fixedly connected to the inner wall of the base 1. A discharge pipe 3 is fixedly connected through the front side of the flocculation box 2. An operation panel 4 is fixedly connected to the front side of the base 1. A support frame 5 is fixedly connected to the bottom of the operation panel 4. A sludge removal device 6 is provided on the side of the operation panel 4. The sludge removal device 6 includes a shell 61. A fixing plate 62 is fixedly connected to the inner wall of the shell 61. A motor 63 is provided on the side of the fixing plate 62. A reciprocating screw 64 is fixedly connected to the end of the output shaft of the motor 63. A reciprocating sleeve 65 is fixedly connected to the circumferential surface of the reciprocating screw 64. A push rod 66 is fixedly connected to the circumferential surface of the reciprocating sleeve 65. A push plate 67 is fixedly connected to the bottom of the push rod 66.

[0028] A brush 68 is fixedly connected to the bottom of the push plate 67, and a discharge groove 69 is provided on the inner wall of the outer shell 61. This design is beneficial to the fact that when the push plate 67 is subjected to force and makes reciprocating horizontal linear motion, the push plate 67 can drive the brush 68 to make reciprocating horizontal linear motion.

[0029] There are two discharge troughs 69. The discharge troughs 69 are circular and are interconnected with the discharge pipe 3. This design is beneficial because when the material flows out of the discharge pipe 3, the material can enter the interior of the outer shell 61 through the discharge troughs 69.

[0030] An auxiliary device 7 is provided inside the outer casing 61. The auxiliary device 7 includes a rectangular groove 71, which is formed on the inner wall of the outer casing 61. A filter plate 72 is fixedly connected to the inner wall of the rectangular groove 71. A filter hole 73 is passed through the top of the filter plate 72. A water storage tank 74 is fixedly connected to the bottom of the outer casing 61. This design is beneficial to the filter plate 72, which can further filter the material when it enters the inner casing 61, and prevent the material from having residual moisture.

[0031] An inclined plate 75 is fixedly connected to the side of the outer shell 61, and a limit block 76 is fixedly connected to the top of the inclined plate 75. This design is beneficial to push the material onto the inclined surface of the inclined plate 75 when the push plate 67 moves, and the material can slide out using the inclined surface of the inclined plate 75.

[0032] Two limiting blocks 76 are provided and are symmetrical to each other along the vertical central axis at the top of the inclined plate 75. This design is beneficial to the limiting blocks 76, which can limit the material when it is displaced by force to the inclined surface of the inclined plate 75, so that the material does not fall from both sides of the inclined plate 75.

[0033] The angle between the inclined plate 75 and the outer shell 61 is less than 90 degrees. The rectangular groove 71 runs through the bottom of the water storage tank 74. The push plate 67 is slidably connected to the inner wall of the outer shell 61. This design is beneficial because when the filter plate 72 filters the material, the filtered water can flow into the water storage tank 74 through the rectangular groove 71.

[0034] A specific application of this embodiment is as follows: First, when the operator starts the external power supply, the motor 63 set on the side of the fixed plate 62 starts to operate, and at the same time, the reciprocating screw 64 fixed at the end of the output shaft of the motor 63 rotates clockwise. When the reciprocating screw 64 rotates clockwise, it forces the reciprocating sleeve 65 threaded to the circumferential surface to make reciprocating horizontal linear motion. When the reciprocating sleeve 65 makes reciprocating horizontal linear motion, it causes the push rod 66 fixed on the circumferential surface of the reciprocating sleeve 65 to make reciprocating linear motion. Then, when the push rod 66 makes reciprocating horizontal linear motion, it drives the push plate 67 fixed at the bottom of the push rod 66 to move, thereby causing the brush 68 fixed at the bottom of the push plate 67 to make reciprocating horizontal linear motion. When the machine dewaters the sludge, it flows out from the discharge trough 69 into the inside of the outer shell 61 through the discharge pipe 3. The push plate 67 pushes out the material flowing out of the discharge trough 69, and the cycle repeats, achieving the slag removal effect, so that the material cannot accumulate inside the outer shell 61, saving the operator's working time.

[0035] Finally, when the machine is performing slag removal, in order to prevent incomplete dehydration of the material, resulting in a small amount of moisture remaining when the material flows into the inner wall of the outer shell 61, the filter plate 72 fixed to the inner wall of the rectangular trough 71 can filter it to a certain extent. When the push plate 67 pushes the material to move, it can push the material onto the inclined plate 75 fixed to the side of the outer shell 61. During this process, the residual moisture in the material will flow into the water storage tank 74 fixed to the bottom of the outer shell 61 through the filter hole 73. At the same time, when the material is pushed to the inclined surface of the inclined plate 75 by the push plate 67, the material will slide down the inclined surface of the inclined plate 75 due to gravity. In order to prevent the material from falling from both sides of the inclined plate 75, the limiting block 76 fixed to the top of the inclined plate 75 can limit it and prevent the material from falling from both sides of the inclined plate 75. The workers can collect the sliding material, which plays an auxiliary role in the slag removal device 6 and improves the work efficiency of the workers.
