Abstract
Description
Technical Field
[0001] This utility model relates to the field of fryer filtration technology, and in particular to a filtration structure for a crayfish fryer. Background Technology
[0002] In the current technological field, the oil filtration systems widely used in crayfish fryers mostly rely on simple, single-layer fixed filter screens. These screens are typically installed in the oil path to intercept food residue and solid particles. However, in actual continuous frying operations, the large amounts of fine debris and gelatinous substances generated in the high-temperature oil easily adhere to the filter screen surface and the inside of the mesh, causing severe blockage in a short time. This leads to a decrease in system flow rate and a sharp drop in filtration efficiency. Operators must frequently disassemble, clean, or replace the filter screen, significantly increasing maintenance workload and labor costs, and severely disrupting the continuous operational stability of the frying equipment, resulting in decreased production efficiency. Simultaneously, blocked oil paths and residue retention accelerate oil deterioration, shorten the lifespan of edible oil, and consequently lead to higher raw material costs and food safety risks. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filter structure for a crayfish fryer.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a filter tube, with rotating grooves at both ends of the top of the filter tube, and a handle is provided inside the two sets of rotating grooves. Four sets of locking blocks are provided along the periphery of the top of the filter tube, and a first filter screen is locked inside the four sets of locking blocks. A guide tube is provided inside the filter tube.
[0005] Preferably, the bottom of the surface of the filter tube is provided with threads, and a second filter screen is threadedly connected to the inner bottom of the filter tube.
[0006] Preferably, a groove is formed in the middle of the top surface of the second filter screen, and a bearing is provided inside the groove.
[0007] Preferably, a cleaning column is provided at the top of the bearing, the bottom of the cleaning column is attached to the top of the second filter screen, and the surface of the cleaning column is attached to the inner wall of the filter tube.
[0008] Preferably, the top of the cleaning column surface has four sets of force grooves along the periphery, and the top of the cleaning column is located at the bottom of the guide tube.
[0009] Preferably, the interior of the guide tube is spiral-shaped.
[0010] Preferably, a flow direction pipe is provided at the bottom of the guide tube.
[0011] Beneficial effects In this invention, the use of a locking mechanism allows for quick installation and removal of the first filter screen; simultaneously, the second filter screen is connected to the filter tube via a threaded connection, which also facilitates installation and removal. The double-layer filter design effectively improves the overall filtration efficiency.
[0012] This invention employs a configuration of bearings, a cleaning column, a force-bearing groove, a guide pipe, and a flow pipe. Driven by oil flow, the cleaning column automatically rotates, continuously scraping away accumulated oil residue from the inner wall of the filter tube and the surface of the second filter screen, effectively preventing clogging. The spiral guide pipe, combined with the bottom flow pipe structure, guides the oil to impact the force-bearing groove, providing stable rotational power for the cleaning column. This enables continuous self-cleaning of the filter tube's internal structure during the filtration process, significantly improving continuous filtration efficiency and equipment operational stability.

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-5A crayfish fryer filter structure includes a circular filter tube 1. Both ends of the top of the filter tube 1 are provided with rotating grooves. The two sets of rotating grooves are provided with handles 2 at both ends. Four sets of locking blocks 3 are provided along the periphery of the top of the filter tube 1. The four sets of locking blocks 3 are connected to a circular first filter screen 4. The size of the first filter screen 4 is adapted to the inner diameter of the filter tube 1. The filter tube 1 has a guide tube 5 inside, and a thread is provided at the bottom of the surface of the filter tube 1. The second filter screen 6 is connected to the thread at the bottom of the filter tube 1. A groove 7 is provided in the middle of the top surface of the second filter screen 6. A bearing 8 is provided inside the groove 7. A cleaning column 9 is provided at the top of the bearing 8. A cleaning cotton is provided at the bottom of the cleaning column 9. The bottom of the cleaning cotton is attached to the top of the second filter screen 6. The cleaning cotton can effectively scrape away the blockage at the top of the second filter screen 6. The surface of the cleaning column 9 is attached to the inner wall of the filter tube 1. Four sets of force grooves 10 are provided along the periphery of the top of the surface of the cleaning column 9. The top of the cleaning column 9 is located at the bottom of the guide tube 5. The top of the guide tube 5 is located at the bottom of the first filter screen 4. The top of the first filter screen 4 is located at the bottom of the handle 2. The inside of the guide tube 5 is spiral. A flow pipe 11 is provided at the bottom of the guide tube 5. The flow pipe 11 is inclined and its bottom port is aligned with the inside of the force groove 10 to ensure that the flow inside the flow pipe 11 can accurately impact the cleaning column 9.
[0018] The operator squeezes handle 2 inward, engaging both ends of handle 2 into the two sets of rotating slots, and then releases it. After release, handle 2 can rotate and connect to the inside of the rotating slots. The connected handle is then tightened with the threads on the bottom of the filter tube and the threads of the external fryer. The outer ring of bearing 8 is fixed inside the groove 7, and the top of the inner ring connects to the bottom of the cleaning column 9. Both the first filter screen 4 and the second filter screen 6 can be quickly installed and removed from the filter tube 1, facilitating subsequent cleaning and maintenance. Specific Implementation Example 2: A crayfish fryer filtration structure, further based on the basic structure in Specific Embodiment 1, operates as follows: Before operation, the filter tube 1 is threadedly connected and fixed to the external fryer using the handle 2. After frying, the oil to be filtered first flows through the top first filter screen 4, initially intercepting larger particles of impurities. The oil then enters the spiral guide tube 5, spiraling downwards along its inner wall. After being concentrated and guided by the bottom flow pipe 11, it precisely impacts the force groove 10 on the surface of the cleaning column 9, driving the cleaning column 9 to rotate around the bearing 8. During rotation, the cleaning column 9 continuously scrapes the surface of the second filter screen 6 and the inner wall of the filter tube 1, effectively removing attached oil residue and preventing mesh blockage. Finally, the fully filtered and cleaned oil flows out from the bottom of the device, completing the entire oil processing process.
[0020] Its working principle is as follows: the filter structure utilizes the flow of the oil itself as the cleaning power. After the oil flows through the spiral guide pipe 5 and the bottom flow pipe 11, it forms a directional impact force that acts on the force groove 10 of the cleaning column 9, thus converting it into rotational torque. The cleaning column 9 is supported by the bottom bearing 8 to achieve flexible rotation. During its rotation, its outer surface and the cleaning cotton at the bottom continuously scrape the inner wall of the filter pipe 1 and the surface of the second filter screen 6, thereby automatically removing the oil residue attached to them, achieving synchronous self-cleaning during the filtration process.
[0021] In summary: 1. The use of locking blocks 3 allows for quick installation and removal of the first filter screen 4; simultaneously, the second filter screen 6 is connected to the filter tube 1 via a threaded connection, which also facilitates installation and removal. This double-layer filter design effectively improves the overall filtration efficiency. 2. The arrangement of bearing 8, cleaning column 9, force groove 10, guide pipe 5, and flow pipe 11 enables the cleaning column 9 to rotate automatically under the drive of oil flow, continuously scraping away accumulated oil residue from the inner wall of filter tube 1 and the surface of the second filter screen 6, effectively preventing clogging. The spiral guide pipe 5, combined with the bottom flow pipe 11, guides the oil to impact the force groove 10, providing stable rotational power for the cleaning column 9. This achieves synchronous self-cleaning of the internal structure of filter tube 1 during the filtration process, significantly improving continuous filtration efficiency and equipment operational stability.
