Description

Technical Field

[0001] The utility model belongs to the technical field of squeezers, and specifically relates to a bidirectional water-filtering single-screw squeezer. Background Art

[0002] The squeezer is a mechanical extrusion dehydration and drying device, which is often used in the deep processing industries of food, grain and feed. It has a good dehydration effect on a variety of materials with high water content, provides energy-saving conditions for the final drying of materials, and greatly reduces the total energy consumption of drying.

[0003] There are many kinds of existing squeezing machines. For example, Chinese invention patent with publication number CN115518436A discloses a high-efficiency squeezing machine, including a bottom beam, a screen cage assembly is installed above the bottom beam, a central spiral shaft is coaxially arranged inside the screen cage assembly, an inner filter assembly is installed on the outer surface of the central spiral shaft, an inner filter chamber is coaxially arranged in the middle of the central spiral shaft, and a slag discharge spiral shaft is rotatably installed in the middle of the inner filter chamber.

[0004] The above-mentioned existing squeezers are all composed of a frame, a feed inlet, a discharge assembly, a screw shaft, a screen cage and a driving device. A filter screen is installed on the inner wall of the screen cage, and the screw shaft is installed in the center of the screen cage. There are several blades on the shaft, and the blade diameter changes with the change of the inner diameter of the screen cage. The material enters from the feed inlet, and the driving device drives the screw shaft to rotate. The blades rotate to push the material forward and squeeze it. The volume of the material in the screen cage also decreases, and the water in it is gradually squeezed out and discharged through the screen. After dehydration, the material becomes loose and the water content is reduced.

[0005] However, during the operation of the existing squeezer, the material cannot smoothly follow the rotation of the screw shaft and enter the discharge assembly. The material will be stuck between the screw shaft and the screen cage, affecting the working efficiency of the squeezer. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a two-way water filtering type single screw squeezer, which can smoothly deliver materials to a discharge seat by a conveying spiral blade by arranging a guide filter plate.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A two-way water filtration type single screw squeezer comprises a base, on which a feed seat and a discharge seat are arranged, a screen cage assembly is arranged between the feed seat and the discharge seat, a central spiral shaft with a plurality of filter holes arranged on the surface is coaxially arranged in the screen cage assembly, a slag discharge spiral shaft is coaxially arranged in the central spiral shaft, a conveying spiral blade is fixedly arranged on the outer surface of the central spiral shaft, and a guide filter plate coated on the surface of the central spiral shaft is arranged between the conveying spiral blades.

[0009] The following is a further optimization of the above technical solution by the utility model:

[0010] The guide filter plate includes a plurality of guide plates and fixed rods. The guide plates are arranged in parallel longitudinally, and the fixed rods are arranged in parallel transversely at the bottom of the guide plates. One side of the fixed rod of the guide filter plate faces the central spiral axis. The material slides on the guide plate, and the sliding is smoother, which can assist in pushing the material forward.

[0011] Further optimization: the guide plate is arranged on the surface of the central spiral shaft along the spiral direction of the conveying spiral blade; during the rotation of the conveying spiral blade, the material is continuously pushed to one side until the material enters the discharge seat. The guide plate is arranged along the spiral direction to make the process of pushing the material smoother and assist the material to enter the discharge seat.

[0012] Further optimization: the screen cage assembly includes an outer filter cage and an outer filter plate, and the outer filter cage and the outer filter plate are coaxially sleeved on the surface of the central spiral shaft; the screen cage assembly and the central spiral shaft work together to extrude the material in the middle. During the extrusion process, part of the liquid enters the central spiral shaft, and part of the liquid flows out from the outside of the screen cage assembly.

[0013] Further optimization: the outer filter plate is a guide filter plate, and the setting direction of the guide plate is consistent with the setting direction of the guide plate on the surface of the central spiral shaft; the guide plates of the two guide filter plates are arranged in the same direction, and together assist the material to move with the conveying spiral blades.

[0014] Further optimization: a machine cover covering the outside of the screen cage assembly is arranged between the feed seat and the discharge seat, and an intermediate water collecting trough is arranged at the bottom of the machine cover; the discharged water in the screen cage assembly will enter the intermediate water collecting trough, and the machine cover plays the role of isolating and protecting the material.

[0015] The beneficial effect of the utility model is that by arranging guide filter plates on the outer side of the central spiral shaft and the inner side of the screen cage assembly, when the material is squeezed and pushed, it can assist the material to move forward in the pushing direction of the conveying spiral blade, so that the material can smoothly enter the discharge seat. During the extrusion process, excess liquid flows from between two adjacent guide plates to the surface of the central spiral shaft, and flows into the interior through the filter holes, which will not affect the discharge of excess liquid, and can also reduce the material from falling into the interior of the central spiral shaft from the through hole, thereby improving work efficiency.
