Description

Technical Field

[0001] This utility model relates to the field of extrusion dehydrator technology, specifically an extrusion dehydrator. Background Technology

[0002] An extrusion dewatering machine is a device that uses mechanical extrusion force to separate moisture from materials, achieving material volume reduction, drying, or solid-liquid separation. Its core principle is to apply pressure to the material through extrusion components (such as filter plates, screws, and pressure rollers), causing moisture to seep out through filter cloth and screens, thereby obtaining a solid filter cake with low moisture content and recyclable filtrate. It is widely used in environmental protection, food processing, chemical industry, agriculture, and many other fields.

[0003] An investigation revealed that a utility model patent discloses a dewatering machine (publication number: CN221505422U), comprising a support frame, with the dewatering machine body fixedly mounted on the top of the support frame. A flip cover is hinged to one side of the bottom middle section of the dewatering machine body, and a sealing strip is fixedly connected to one end of the flip cover. One end of the sealing strip presses against one side of the inner wall of the dewatering machine body. Mounting buckles are fixedly mounted on both corners of the top of the flip cover. This utility model, through the combination of the flip cover, sealing strip, mounting buckles, and bolts, allows the dewatering machine body to loosen from the flip cover by loosening the bolts connecting the mounting buckles and the dewatering machine body after the operation is completed. Further rotation of the flip cover opens the central part of the dewatering machine body. Therefore, when the dewatering machine body is closed, the adhering and clogging waste in the central part of the dewatering machine body can be processed, thus effectively avoiding the situation where the blockage cannot be processed quickly.

[0004] Although the aforementioned patent improves the ease of use of the dewatering machine by designing components such as flip-tops, sealing strips, and bolts, and by cooperating with each component, and makes cleaning easier by opening the cover, the extrusion dewatering machine often requires continuous extrusion of the material by the extrusion blades during use, causing the liquid to flow out from the filter screen. Over time, the filter screen is prone to clogging, leading to reduced liquid discharge efficiency, which is very detrimental to improving the efficiency of the dewatering extrusion machine.

[0005] Therefore, this utility model provides an extrusion dehydrator to solve the above problems. Utility Model Content

[0028] 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.

[0029] This utility model provides an extrusion dehydrator, such as Figures 1-5 As shown, the extrusion dewatering machine includes a machine chamber 1 and a cleaning assembly, the cleaning assembly including a receiving chamber 2 installed on the outer wall of the machine chamber 1;

[0030] The receiver 1 has a filter tank 3 on one side wall of the receiving chamber 2. There are several filter tanks 3. A drive motor 4 is installed at one end of the receiving chamber 2. The output end of the drive motor 4 is coaxially driven by a reciprocating screw 6 through a coupling sleeve 5. A cleaning brush 7 is threaded onto the outer wall of the reciprocating screw 6. The cleaning brush 7 slides on the inner wall of the receiving chamber 2. A circulation component is provided on the outer wall of the receiving chamber 2.

[0031] The circulation assembly includes a circulation chamber 8 installed on the outer wall of the receiving chamber 2. The outer wall of the receiving chamber 2 is fixedly connected to the inner wall of the circulation chamber 8 through a drain pipe 9. The inner wall of the circulation chamber 8 is respectively equipped with a filter plate 10 and an adsorption plate 11.

[0032] A circulation pump 12 is installed at the bottom of the circulation chamber 8, and a circulation pipe 13 is installed on the side wall of the circulation chamber 8. One end of the circulation pipe 13 is fixedly connected to the output end of the circulation pump 12, and the other end of the circulation pipe 13 is fixedly connected to the inner wall of the machine chamber 1.

[0033] Specifically, through the arrangement of the cleaning components, the various parts work together during the material extrusion and dewatering process. The drive motor 4, reciprocating screw 6, and cleaning brush 7 work in tandem. The rotating reciprocating screw 6 drives the cleaning brush 7, which is threaded onto its outer wall, to continuously reciprocate, thus cleaning and scraping the filter grooves 3 on the outer wall of the machine chamber 1. This continuous cleaning prevents material debris from clogging the filter grooves 3, thereby improving the rapid discharge of liquid and increasing dewatering efficiency. Furthermore, the circulation component allows for the collection of liquid discharged from the material via the drain pipe 9. When recyclable liquid is encountered, it can be collected in the unified circulation chamber 8. The process involves collecting materials to improve processing quality and equipment applicability. The filter plates 10 and adsorption plates 11 in the circulation chamber 8 can filter the extruded liquid, preventing it from being adsorbed by the circulation pump 12. The adsorption plates 11 can adsorb impurities in the liquid, further improving the liquid treatment effect. The circulation pump 12, in conjunction with the circulation pipe 13, can pump the treated liquid. This allows for rinsing the inner wall of the chamber 1 during extrusion, further improving the cleanliness of the chamber 1 and reducing the probability of material blockage. It also allows for rinsing the inside of the chamber 1 after extrusion and dehydration, improving the cleanliness of the equipment.

[0034] A stirring motor 14 is installed at the end of the machine compartment 1. A drive shaft 15 is coaxially driven at the output end of the stirring motor 14. An extrusion blade 16 is fixedly sleeved on the outer wall of the drive shaft 15.

[0035] A feeding bin 17 is installed at the top of the machine compartment 1. A servo motor 18 is installed on the outer wall of the feeding bin 17. A crushing roller 19 is installed at the output end of the servo motor 18. There are two crushing rollers 19.

[0036] Gears 20 are fixedly sleeved on the outer walls of the two crushing rollers 19, and the outer walls of the two gears 20 mesh for transmission.

[0037] Specifically, the stirring motor 14 installed at the end of the machine chamber 1 drives the drive shaft 15 at its output end to rotate, thereby using the extrusion blades 16 to continuously extrude the material in conjunction with the machine chamber 1, improving its dewatering effect. The feeding hopper 17 at the top of the machine chamber 1 allows for the feeding process of the material. The continuously rotating servo motor 18 drives the crushing rollers 19 at its end to rotate. The rotation of the two crushing rollers 19 initially crushes the material, reducing its particle size and thus improving the material dewatering efficiency. The meshing transmission of the gears 20 allows the two rollers to move rapidly, improving the crushing efficiency of the material and thus improving the material dewatering efficiency.

[0038] A discharge rack 21 is fixedly connected to the end of the machine compartment 1, and a baffle plate 23 is fixedly connected to the inner wall of the discharge rack 21 by a compression spring 22.

[0039] Specifically, the discharge rack 21 set at the end of the machine compartment 1 can be used to connect the baffle plate 23 with the compression spring 22. Due to the material properties of the compression spring 22, the baffle plate 23 continuously squeezes the machine compartment 1. When the material accumulates, it pushes out of the baffle plate 23, so that the material is pushed out of the machine compartment 1 to complete the material compression and dehydration.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
