Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed filtration, in particular to a filter device for rapeseed oil processing. Background Art

[0002] The existing rapeseed oil filtration technology mainly adopts air pressure and vacuum structures, combined with multiple layers of filter cloth or filter paper for oil filtration; the patent number CN221181999U discloses a high-temperature edible oil filter, which sets a filtering component to make the oil in the container rotate at high speed under high-pressure impact and generate centrifugal force to achieve the purpose of separating solid and liquid, improving the filtering effect of edible oil, but it cannot select the number of filter plates for different rapeseed oil feedstocks, so the use efficiency is not high.

[0003] Specifically, the existing rapeseed oil filters cannot flexibly replace the filter paper, cannot select the number of filter plates, and are difficult to clean subsequently. Therefore, there is an urgent need for a new filter device for rapeseed oil processing to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a filter device for rapeseed oil processing to solve the problems in the above background.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] A filter device for rapeseed oil processing includes: a filtration chamber, filter plates, an oil suction pump and an air pump. A positioning pin is vertically fixed at the bottom of the filtration chamber, and a plurality of filter plates are sleeved on the positioning pin. One side of the plurality of filter plates is sequentially provided with oil suction pipes at corresponding height positions.

[0007] A bottom chamber is provided at the bottom of the filtration chamber, and an oil suction pump and an air pump are arranged in the bottom chamber. The output end of the oil suction pump faces the surface of the filter plate, and the output end of the air pump inputs pressurized air into the surface of the filter plate.

[0008] The upper end of the oil suction pipe penetrates through the side wall of the filtration chamber, and the lower end of the oil suction pipe penetrates through the upper wall of the bottom chamber.

[0009] A filter element is provided in the middle of the filter plate, and an opening is provided on one side of the filter element, and a connecting pipe is sleeved in the opening.

[0010] An oil suction valve is installed on the oil suction pipe, and the input end of the oil suction pipe is communicated with the connecting pipe. The raw rapeseed oil to be filtered is sent into the filtration chamber through the oil suction pump. After starting the air pump to pressurize, the oil is pushed to pass through multiple layers of filter cloth or filter paper, and the filtered oil is introduced into the oil suction pipe through the filter element and discharged, while the impurities are retained on the filter plate; after the filtration is completed, the air pump stops pressurizing, the filter cloth is taken out to clean the impurities on it, and the position of the filter plate is fixed by the positioning pin to ensure stable oil suction.

[0011] The bottommost oil suction pipe is connected with a special drying valve. The output ends of multiple oil suction pipes are connected to a diversion pipe through connecting pipes. The diversion pipe is connected with a fine filtration oil outlet valve. When the rapeseed oil volume is large, by opening multiple oil suction valves, the corresponding connected connecting pipes filter the oil and introduce it into the diversion pipe and then export it from the fine filtration oil outlet valve. When starting the oil suction pump for final oil suction, only the special drying valve is opened, and the air pump is started to pressurize the bottom filter plate to filter out the residual oil.

[0012] By adjusting the number of oil suction valves opened by multiple filter plates, the oil suction pipes at the corresponding heights can be started to facilitate the uniform distribution of the oil liquid, so as to cope with the fine filtration and residue removal steps of rapeseed oil with different volumes, different processing procedures, and different oil temperatures, improving the applicability of the filter to rapeseed oil.

[0013] The upper part of the filtration chamber is hinged with a machine cover. An air outlet valve is arranged on the upper surface of the machine cover. A pressure gauge is connected to the upper surface of the machine cover on one side of the air outlet valve. The top of the machine cover is screwed back to the pressure gauge air pump and the air outlet valve for pressure relief. Before filtration, the air outlet valve is closed, and the pressure gauge monitors the internal pressure of the filtration chamber. When compressed air is added to reach the corresponding value, pressure is formed inside the oil filter to push the oil to linearly pass through the filter cloth and filter paper.

[0014] The upper surface of the bottommost filter plate is of an arc structure. Springs are installed on both sides of the filter plate. Filter paper is clamped on the upper and lower sides of the filter plate through the elastic ends of the springs.

[0015] The pore size mesh number of the filter paper is larger than that of the filter plate. Filter paper with higher precision and replaceable is arranged on both sides of the filter plate. The filter paper can be flexibly replaced through the springs. The arc-shaped design on both sides of the bottommost filter plate ensures that the hot oil filtered out after using the special drying valve will not remain in the filtration chamber.

[0016] The beneficial effects of the present utility model:

[0017] 1. By designing oil suction pipes, connecting pipes and filter paper at corresponding heights and using them in combination with a special drying valve and a fine filtration oil outlet valve, the present utility model is convenient for stably processing different incoming rapeseed oil. After the oil filtration is completed, for the treatment of the residual oil, by opening the special drying valve and starting the air pump to pressurize the bottom filter plate, the residues in the oil are efficiently filtered out, avoiding waste and reducing the subsequent cleaning burden. According to rapeseed oil with different volumes, by adjusting the number of oil suction valves on the filter plate, the device can flexibly meet different processing requirements.

[0018] 2. The arc-shaped design of the bottommost filter plate of the present utility model effectively ensures that after the drying process, the hot oil will not affect subsequent operations or increase potential safety hazards due to remaining in the filtration chamber, realizing the safety and convenience of equipment operation; filter paper that is easy to replace is installed on both sides of the filter plate, and the filtration precision can be flexibly adjusted according to the filtration requirements.

A plurality of oil suction pipes 7 are sequentially arranged on one side of the plurality of filter plates 2 at corresponding height positions;

[0028] A bottom chamber 10 is provided at the bottom of the filtration chamber 1. An oil suction pump 8 and an air pump 12 are provided in the bottom chamber 10. The output end of the oil suction pump 8 faces the surface of the filter plate 2, and the output end of the air pump 12 inputs pressurized air into the surface of the filter plate 2.

[0029] The upper end of the oil suction pipe 7 penetrates through the side wall of the filtration chamber 1, and the bottom end of the oil suction pipe 7 penetrates through the upper arm of the bottom chamber 10.

[0030] The middle of the filter plate 2 is provided with a filter element 4. One side of the filter element 4 has an opening, and a connecting pipe 5 is sleeved in the opening.

[0031] An oil suction valve 6 is installed on the oil suction pipe 7. The input end of the oil suction pipe 7 is communicated with the connecting pipe 5. The initial pressed rapeseed oil to be filtered is sent into the filtering cavity 1 through the oil suction pump 8. After starting the air pump 12 to pressurize, the oil in it is pushed to pass through the multi-layer filter cloth or filter paper 3. Then, the filtered oil is introduced from the filter element 4 into the oil suction pipe 7 and discharged, and the impurities are retained on the filter plate 2. After the filtration is completed, the air pump 12 stops pressurizing, the filter cloth is taken out to clean the impurities on it, and the position of the filter plate 2 is fixed by the positioning pin 9 to ensure stable oil suction.

[0032] Please refer to Figures 3 - 4 As shown, the bottommost oil suction pipe 7 is communicated with a special drying valve 17.

[0033] When the amount of rapeseed oil is large, by opening multiple oil suction valves 6, the corresponding connected connecting pipes 5 filter the oil and introduce it into the diversion pipe 16 and then export it from the fine filtration oil outlet valve 15. When starting the oil suction pump 8 for final oil suction, only the special drying valve 17 is opened, and the air pump 12 is started to pressurize the bottommost filter plate 2 to filter out the residual oil.

[0034] By adjusting the number of oil suction valves 6 opened on multiple filter plates 2, the oil suction pipes 7 at the corresponding heights can be started to facilitate the uniform distribution of the oil liquid, so as to cope with the fine filtration and residue removal steps of rapeseed oil with different volumes, different processing procedures, and different oil temperatures, and improve the applicability of the filter to rapeseed oil.

[0035] The upper part of the filtering cavity 1 is hinged with a machine cover 11. An air outlet valve 13 is arranged on the upper surface of the machine cover 11, and a pressure gauge 14 is communicated with the upper surface of the machine cover 11 on one side of the air outlet valve 13.

Before filtration, the air outlet valve 13 is closed, and the pressure gauge 14 monitors the internal air pressure of the filtering cavity 1. When compressed air is added to reach the corresponding value, a pressure is formed inside the oil filter to push the oil to linearly pass through the filter cloth and filter paper 3.

The filter paper 3 can be flexibly replaced through the spring 21. The two sides of the bottommost filter plate 2 are set as arcs to ensure that the hot oil filtered out after using the special drying valve 17 will not remain in the filtering cavity 1 and affect subsequent operations.

[0039] Working principle of the utility model: Before filtration, the air outlet valve 13 is closed, and the pressure gauge 14 monitors the air pressure inside the filtration chamber 1. When compressed air is added to reach the corresponding value, pressure is formed inside the oil filter.

[0040] Start the oil suction pump 8 to send the initially pressed rapeseed oil to be filtered into the filtration chamber 1. After starting the air pump 12 to pressurize, the oil therein is pushed to pass through multiple layers of filter cloth or filter paper 3, and then the filtered oil is introduced from the filter element 4 into the oil suction pipe 7 and discharged, while the impurities are retained on the filter plate 2.

[0041] After filtration is completed, the air pump 12 stops pressurizing, and the filter cloth is taken out to clean the impurities on it.

[0042] When the amount of rapeseed oil is large, by opening multiple oil suction valves 6, the corresponding connected connecting pipes 5 filter the oil and then introduce it into the diversion pipe 16 and then export it from the fine-filtered oil outlet valve 15.

[0043] When sucking oil at the end, only open the special drying valve 17 to filter out the residual oil.
