Technical Field

[0001] The utility model relates to the technical field of rapeseed oil production equipment, in particular to a rapeseed oil sludge scraping device. Background Art

[0002] Rapeseed oil is an edible oil extracted from rapeseed. It has a unique flavor and high nutritional value. Rapeseed oil sludge is a sediment formed during the storage or use of rapeseed oil due to various reasons. This sediment may contain impurities, oxidation products, insoluble substances, etc. The presence of sludge may affect the quality and performance of the rapeseed oil and may also have certain impacts on storage containers and equipment.

[0003] A rapeseed oil sludge scraping device with application number CN202420464360.6 includes a frame body and a filter screen arranged at the bottom of the frame body, and also includes a scraping assembly arranged inside the frame body. The scraping assembly includes a first scraper blade and a second scraper blade. The first scraper blade is arranged between the vertical walls on both sides of the longitudinal direction of the frame body and can slide along the length direction of the frame body. The bottom of the first scraper blade abuts against the upper surface of the filter screen. The second scraper blade is arranged in the first scraper blade and can slide up and down in the first scraper blade. Filter holes are provided on the first scraper blade and the second scraper blade.

[0004] The above patent document has the beneficial effect of using an electromagnet to allow the first scraper to fit tightly against the horizontal vertical wall of one side of the frame body, thereby squeezing out the grease in the sludge to prevent waste. However, the method of cleaning the sludge only by using the scraper is relatively simple. Some of the sludge accumulates in the filter holes of the filter screen and cannot be completely scraped off by the scraper alone, resulting in a decrease in the efficiency of filtering the grease during subsequent use. Some of the sludge may also contaminate the rapeseed oil again. Utility Model Content

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 4 A rapeseed oil sludge scraping device includes a frame body 1, a filter screen 2, and a scraper 3. The inner wall of the frame body 1 is fixedly connected to the filter screen 2, and the scraper 3 is slidably connected to the inner wall of the filter screen 2. Filter hole cleaning devices 4 for cleaning the sludge on the filter screen are provided on both sides of the scraper 3. Auxiliary moving devices 5 for helping the scraper 3 to move are provided on both sides of the frame body 1. A sludge discharge port 6 that can be opened and can discharge the sludge is opened on one side of the outer wall of the frame body 1.

[0022] It should be noted that the high-pressure water pump 16 and the water pump 17 are existing technologies, and the specific model specifications need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0023] Furthermore, the auxiliary moving device 5 includes a symmetrically distributed L-shaped plate 7, a slide 8, a block 9, a slide groove 10, a connecting clamp 11, and a roller 12. The L-shaped plate 7 is fixedly connected to the outer walls of both ends of the scraper blade 3, the slide 8 is fixedly connected to the front and rear outer walls of the frame body 1, the block 9 is fixedly connected to the left and right outer walls of the slide 8, and the slide groove 10 is arranged on the outer wall of the slide 8.

[0024] Among them, the inner walls of the L-shaped plates 7 on both sides are provided with rollers 12, which makes the movement of the scraper 3 smoother and greatly reduces the phenomenon of jamming on one side.

[0025] Furthermore, the connecting clamp 11 is fixedly connected to the inner wall of the L-shaped plate 7, the connecting clamp 11 is slidingly connected to the inner wall of the slide groove 10, the roller 12 is rotationally connected to the inner wall of the connecting clamp 11, and the roller 12 can roll on the inner wall of the slide groove 10.

[0026] Among them, the function of the block 9 is to prevent the connecting clamp 11 and the roller 12 from escaping from the slide groove 10. When the roller 12 moves to fit with the block 9, the scraper blade 3 fits with the outer wall of one side of the frame body 1.

[0027] Furthermore, the filter pore cleaning device 4 includes a liquid storage tank 13, a clean water chamber 14, a cleaning liquid chamber 15, a high-pressure water pump 16, a water pump 17, a hose 18, a connecting plate 19, a connecting pipe 20, and a nozzle 21. The liquid storage tank 13 is arranged below the frame body 1, the clean water chamber 14 is arranged on the left side inside the liquid storage tank 13, and the cleaning liquid chamber 15 is arranged on the right side inside the liquid storage tank 13.

[0028] The cleaning liquid chamber 15 is filled with a solution specifically for dissolving sludge, which is extracted by the water pump 17 and transported to the connecting pipe 20 for spraying out, thereby decomposing and melting the sludge in the filter holes, making it easier to clean.

[0029] Furthermore, a high-pressure water pump 16 is arranged at the bottom end of the inner wall of the clean water chamber 14, a water pump 17 is arranged at the bottom end of the inner wall of the cleaning liquid chamber 15, one end of a hose 18 is arranged in the liquid storage tank 13 and is respectively connected to the high-pressure water pump 16 and the water pump 17, and the other end of the hose 18 is connected to the connecting plate 19.

[0030] Among them, hot water can be sprayed onto the filter screen 2 in a high-pressure manner through the high-pressure water pump 16, so that the filter holes of the filter screen 2 are rinsed more cleanly, and the whole process is manually controlled, which makes cleaning more convenient.

[0031] Furthermore, the connecting plate 19 is fixedly connected to the outer wall of the scraper blade 3 , the connecting pipe 20 is connected through the inner wall of the connecting plate 19 , and the nozzle 21 is connected through the outer wall of the connecting pipe 20 .

[0032] The hose 18 is a silicone tube that meets the length requirements and has a sufficient length so that the scraper 3 will not be restricted by the length of the hose 18 when moving.

[0033] Working principle: When using this device, first scrape the sludge on the surface of the filter 2 with the scraper 3 and discharge it from the mud discharge port 6, then the solution for dissolving the sludge mixed with hot water can be injected into the cleaning liquid chamber 15, and then the water pump 17 is started. The water pump 17 extracts the solution and transports it to the right connecting pipe 20 through the right hose 18, and finally sprays it out from the nozzle 21 and sprays it onto the filter 2. At this time, the scraper 3 is manually moved to make the L-shaped plate 7 and the roller 12 move back and forth on the slide 10, so that the solution can be sprayed more evenly, and then the high-pressure water pump 16 is started to extract the clean hot water in the clean water chamber 14, and transport it to the left connecting pipe 20 through the left hose 18, and finally sprayed out through the nozzle 21 to perform the final flushing of the surface and filter holes of the filter 2. The dissolved sludge can be flushed more easily, so that the sludge in the filter holes can be cleaned, so that the efficiency of subsequent grease filtration is improved, and the rapeseed oil will not be contaminated for the second time.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
