Description

Technical Field

[0001] The invention relates to the technical field of filtration, in particular to a filtration device used for food mechanical processing. Background Art

[0002] Filtration is the process in which the liquid (or gas) in a suspension (or hot gas containing solid particles) passes through a medium under the action of a driving force or other external force, and solid particles and other substances are retained by the filter medium, thereby separating the solids and other substances from the liquid (or gas). A filtering device for food mechanical processing described in a patent application with publication number CN111544940A includes a filter tank, an upper end cover is installed at the upper end of the filter tank, a feed pipe is installed on one side of the sealing cover and located on the upper surface of the upper end cover, a rotating shaft is installed inside the filter tank below the grinding motor, a grinding head is installed at one end of the rotating shaft, and a grinding base is provided below the grinding head.

DETAILED DESCRIPTION

[0016] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a filtering device for food mechanical processing, comprising a filter 2, a liquid injection port 1 is arranged at the top of the filter 2, a liquid outlet 5 is arranged at the bottom of the filter 2, and a multi-stage pressure relief mechanism 3 is arranged inside the filter 2; The multi-stage pressure relief mechanism 3 comprises: The fixing ring 301 is a hollow ring structure. The outer wall of the fixing ring 301 is fixedly connected to the inner wall of the filter 2. The hollow part of the fixing ring 301 is used to allow oil to pass through. The inner wall of the fixing ring 301 is provided with a connecting groove 302. The annular groove 303 is formed in the inner wall of the fixing ring 301. A circular groove 304 is formed on the outer side of the fixing ring 301. The annular groove 303 is connected to the circular groove 304. A push block 305 is slidably connected to the inner wall of the circular groove 304. One side of the push block 305 is an inclined surface. A vertical baffle 317 is fixedly connected to the inner wall of the annular groove 303. The oil to be filtered is pressurized and input into the liquid injection port 1 through the pressure pump, enters the filter 2 through the liquid injection port 1, passes through the middle of the fixing ring 301, and enters the filter cartridge 6. The oil is filtered by the filter cartridge 6 and discharged through the liquid outlet 5 at the bottom of the filter 2 after filtration. In the case of pressurized injection, there is a high pressure state between the filter cartridge 6 and the injection port 1. At this time, the oil is pressurized and will enter the annular groove 303 through the connecting groove 302 opened in the middle of the fixed ring 301. A vertical baffle 317 is provided in the annular groove 303, so the oil entering the annular groove 303 is blocked by the vertical baffle 317 and flows in a single direction in the annular groove 303. The flow direction is clockwise in the annular groove 303 based on the top view of the fixed ring 301.

[0017] Example 2: Please refer to Figure 1-12 On the basis of the first embodiment, the present invention provides a technical solution: one end of the push block 305 is fixedly connected to a spring 306, one end of the spring 306 is fixedly connected to a connecting plate 308, an annular fixing plate 309 is arranged outside the filter 2, a circular through groove 316 is opened on the inner wall of the annular fixing plate 309, and one end of the spring 306 is fixedly connected to the inner wall of the circular through groove 316 through the connecting plate 308.

[0018] The annular fixing plate 309 is provided with 318 , the inner wall of 318 is fixedly connected to a fixing vertical plate 310 , the outer wall of the fixing vertical plate 310 is fixedly connected to a fixing rod 311 , and one end of the fixing rod 311 is fixedly connected to the outer wall of the filter 2 .

[0019] A stopper 307 is fixedly connected to one side of the connecting plate 308 , and the stopper 307 is cylindrical in shape.

[0020] The interior of the communicating groove 302 is communicated with the interior of the filter 2 , the interior of the annular groove 303 is communicated with the interior of the circular slide groove 304 , and the vertical height of the annular groove 303 is smaller than the diameter of the push block 305 .

[0021] The outer wall of the filter 2 is fixedly connected with a fixing block 312, a magnetic groove A313 is opened on one side of the fixing block 312, and magnetic grooves B314 are opened on both sides of the push block 305. The magnetic grooves A313 and the magnetic grooves B314 are magnetic, and the magnetism of the opposite side of the magnetic groove A313 and the magnetic groove B314 is that opposite poles attract each other; When the oil flows in the annular groove 303, it will first contact the push block 305 in the annular groove 303, and each push block 305 completely seals the inside of the annular groove 303. Therefore, at this time, the high-pressure oil will first resist the first push block 305, and exert a force in the direction of the spring 306 on the push block 305 through the inclined surface of the push block 305. Since the two sides of the push block 305 maintain magnetic attraction with the magnetic groove A313 in the fixed block 312 through the magnetic groove B314, a certain pressure is required to be greater than the magnetic attraction between the magnetic groove B314 and the magnetic groove A313. Under normal pressurized filtration, the pressure of the oil is The push block 305 cannot be pushed out. Once the pressure is too high, the pressure refers to a pressure greater than the preset magnetic attraction force of the magnetic groove A313 and the magnetic groove B314. At this time, the oil in the filter 2 is in an over-high pressure state. At this time, the magnetic groove B314 on the outer wall of the push block 305 will be separated from the magnetic attraction between the magnetic groove A313, so that the push block 305 is pushed by the pressure of the oil and slides vertically in the circular slide groove 304 to slide out and squeeze the spring 306 with weak elastic force. The spring 306 has a weak elastic force and is only used to reset the push block 305. The weak elastic force will not interfere with the push block 305 sliding out under high pressure. When the push block 305 slides out of the circular slide groove 304, it abuts against the stopper 307, limiting the push block 305 to prevent it from falling out. As the push block 305 is pushed out, the push block 305 will open the communication of the annular grooves 303 on the left and right sides of the push block 305 that were originally closed, and the oil will begin to fill the next push block 305, thereby increasing the volume of the oil filled between the liquid injection port 1 and the filter cartridge 6, thereby releasing the pressure and returning the pressure to a normal value, realizing automatic pressure relief, and preventing the filter cartridge 6 from being squeezed due to excessive pressure, causing the filter element inside the filter cartridge 6 to deform and causing the oil filtering effect to deteriorate. The pushed push block 305 can be observed in real time through the outer wall of the filter 2, and the collision sound generated by the push block 305 and the stopper 307 when the push block 305 is quickly pushed out effectively reminds the surrounding staff of the problem of increased pressure here, and no electronic equipment is used, and filtering work can be performed at various positions without pulling wires. After one push block 305 is pushed away, as the oil continues to flow inward along the annular groove 303, the volume of the oil increases, and the oil pressure naturally decreases. Once the pressure continues to rise, the next push block 305 will be pushed away, so that after the next push block 305 is pushed away, the oil continues to flow and releases the pressure. Through several push blocks 305, a continuous pressure relief effect under the continuous pressure increase is achieved, and the internal pressure level at this time and the amount of subsequent pressure relief can be judged by the number of push blocks 305 that are ejected, thereby further preventing accidents from occurring, resulting in pressure increase, oil temperature increase, and poor filtering effect caused by deformation of the filter cartridge 6. Example 3: Please refer to Figure 1-14 On the basis of the first and second embodiments, the present invention provides a technical solution: a multi-stage cooling mechanism 4 is arranged on the outer wall of the push block 305, and the multi-stage cooling mechanism 4 includes a vertical groove 401, and the vertical groove 401 is opened on the side of the push block 305 provided with the inclined surface, and an annular heat dissipation groove 402 is opened on the other side of the push block 305, and the inner wall of the circular through groove 316 is fixedly connected to the connecting block 405, and the outer wall of the connecting block 405 is fixedly connected to the arc-shaped heat conducting plate 403.

[0022] A vertical heat dissipation groove 404 is provided on the inner wall of the arc-shaped heat conducting plate 403. The arc of the arc-shaped heat conducting plate 403 is the same as that of the annular heat dissipation groove 402 and they are concentric arcs. A magnetic block 406 is fixedly connected to one end of the stopper 307. The center position of the push block 305 close to the spring 306 is magnetic. The magnetic block 406 is magnetic. The center position of the push block 305 and the side opposite to the magnetic block 406 are magnetic with opposite poles attracting each other. When the oil is in the filter 2, it will contact the fixing ring 301, and the heat generated by the high pressure during the high-pressure filtration of the oil and the working heat generated by the operation of some equipment will be transferred to the push block 305 inside the fixing ring 301, and the push block 305 will contact the external air through one side of the push block 305, and the annular heat dissipation groove 402 on the contact surface with the air will be used to achieve efficient heat dissipation, and after the push block 305 is pushed out, the vertical groove 401 provided on the outer wall of the push block 305 will contact the oil, further improving the heat absorption efficiency of the push block 305 for the oil, so as to achieve the state of abnormal pressure increase, when the oil temperature rises rapidly, the vertical groove 401 exposed after the push block 305 is pushed out to improve the heat dissipation effect of the oil, so as to prevent the temperature of the mechanical equipment from rising under the abnormal high pressure state at this time, and the oil temperature from rising due to the high pressure, and the oil temperature from being too high when the oil temperature rises here, which will cause the filter element structure inside the filter cartridge 6 to be more easily deformed, thereby affecting the filtering effect of the oil, and also avoiding the deterioration problem caused by the increase in oil temperature; After the push block 305 is pushed out, it will contact the arc-shaped heat-conducting plate 403, and the arc shape of the arc-shaped heat-conducting plate 403 is the same as the inner wall of the annular heat dissipation groove 402, so at this time, the arc-shaped heat-conducting plate 403 will be embedded in the annular heat dissipation groove 402 one by one, and the higher temperature on the push block 305 will be quickly transferred to the arc-shaped heat-conducting plate 403 through heat transfer, and the contact area with the air will be increased by using the several vertical heat dissipation grooves 404 on the arc-shaped heat-conducting plate 403, thereby more effectively connecting the push block 305 with the oil inside the filter 2, so as to achieve The rapid cooling effect under abnormal high-pressure conditions, while under normal high-pressure conditions where the push block 305 is not pushed out, normal and slow heat dissipation can be performed through the annular heat dissipation groove 402, avoiding the problem that the temperature in the oil is too low due to excessive heat dissipation under normal conditions, and the viscosity of the oil increases significantly, affecting the oil filtration efficiency. It also achieves the corresponding high-efficiency heat dissipation effect in real time under abnormal high-pressure conditions when the temperature of each electrical appliance is overloaded and the pressure increases, and when the high-pressure temperature of the oil increases, the corresponding working function is performed according to different situations.

[0023] After the final filtration is completed, the pressure is no longer applied, and the remaining oil above the filter cartridge 6 is pumped away. At this time, the push block 305 is against the magnetic block 406 on the stop block 307, and the center of the push block 305 and the magnetic block 406 are magnetically attracted to each other with opposite poles, so that the push block 305 remains in a magnetically close state with the magnetic block 406, and the oil inside the annular groove 303 is discharged through the ramp groove 315, completing the automatic release of the oil in the annular groove 303, and then each pushed out push block 305 is manually retracted here, so that the push block 305 and the magnetic block 406 are separated from the magnetic attraction, and are automatically rebounded to their original positions by the spring 306, and are kept stationary by the magnetic grooves B314 and A313 on both sides of the push block 305, so that they can wait for the next work.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
