Description

Technical Field

[0001] This utility model relates to the field of peanut milk production and processing technology, and in particular to a negative pressure collection device for peanut shells. Background Technology

[0002] In the peanut processing industry, the collection and processing of peanut shells is an indispensable step. Traditional methods of peanut shell collection mainly involve manual sweeping and simple vacuum cleaners. Manual sweeping is inefficient and easily generates dust during the process, affecting the working environment and potentially harming the health of operators. Simple vacuum cleaners have poor filtration effects; fine particles from the peanut shells easily clog the filter screen, leading to reduced suction and poor collection efficiency. Furthermore, these devices often lack effective sealing structures, making leakage during collection prone to secondary pollution. The filters of traditional collection equipment are difficult to disassemble and clean, and their performance deteriorates over time, requiring frequent filter replacements, increasing operating costs and maintenance workload. With the large-scale development of the peanut processing industry, the demand for efficient, environmentally friendly, and easy-to-maintain peanut shell collection devices is becoming increasingly urgent. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a peanut shell negative pressure collection device. This device achieves efficient negative pressure collection, improving the efficiency of shell collection and processing. It rapidly collects shells through a multi-layer filter structure. Multiple filter media work together: the first layer primarily filters the shell material, requiring regular cleaning to maintain efficient and stable shell collection; the second layer filters again, preventing small-sized shells from directly entering the negative pressure pump and accumulating; and the second layer further breaks down the shells after the first layer, preventing excessive residue buildup in the negative pressure pump, which would affect equipment lifespan and reduce cleaning frequency. The first-layer filter unit is angled to increase the filter media area and improve filtration efficiency. The second layer intercepts and further breaks down small-sized shells, preventing blockage and ensuring stable operation of the negative pressure pump. The load on the first-layer filter unit is determined by the jet velocity at the tail end, allowing for timely replacement and cleaning to maintain efficient and stable filter media collection.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a negative pressure collection device for peanut shells, including a collection box, the top of which is connected to an air inlet pipe, the bottom side of which is connected to an air outlet pipe, a negative pressure suction pump and a sleeve on the air outlet pipe, the collection box being connected to an opening and closing door via a hinge structure, the opening and closing door being magnetically engaged with the collection box and having a handle structure thereon, the collection box containing multiple sets of detachable first filter material structures, and the sleeve having second filter material structures at both ends.

[0005] In a preferred embodiment, the first filter media structure includes a filter plate, with mounting plates at both ends of the filter plate, and a first filter screen on the filter plate. The mounting plates at both ends of the filter plate are detachably and detachably fitted with mounting grooves provided on the inner walls of both sides of the collection box.

[0006] In a preferred embodiment, the filter plate is arranged obliquely inside the collection box, and the width of the filter plate is consistent with the width of the space inside the collection box.

[0007] In a preferred embodiment, the collection box has a sealing groove at its open end, and the opening and closing door has a sealing strip that cooperates with the sealing groove.

[0008] In a preferred embodiment, the outlet end of the vent pipe is equipped with a gas flow rate sensor, and the gas flow rate sensor is connected to a warning light installed on the door via a circuit.

[0009] In a preferred embodiment, the second filter material structure is disposed inside the sleeve and the distance between the second filter material structure and the end of the sleeve is greater than ten centimeters.

[0010] In a preferred embodiment, the second filter material structure is welded and fixed to the outer frame of the inner wall of the sleeve. The outer frame is provided with a second filter screen. A fixed platform is provided at the center of the second filter screen. A rotating shaft is provided on the fixed platform. Multiple sets of blades are provided on the rotating shaft. One of the multiple sets of blades is provided with multiple sets of bristles that cooperate with the second filter screen. The remaining blades are all connected to the shredder blade through a fixed arm.

[0011] The peanut shell negative pressure collection device provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0012] (1) High-efficiency negative pressure collection improves the efficiency of fruit peel collection and processing, and fruit peel is quickly collected through a multi-layer filter structure;

[0013] (2) Multiple filter media are used in combination. The first layer mainly filters fruit peel materials and cleans them regularly to keep fruit peel collection efficient and stable. The second layer is used for secondary filtration to prevent small-sized fruit peels from entering the negative pressure pump directly and accumulating. It breaks up the fruit peels and further breaks down the small-sized fruit peels after passing through the first layer of filter media, so as to avoid excessive residue accumulation in the negative pressure pump, which would affect the equipment life and reduce the cleaning frequency.

[0014] (3) The first filter unit is set at an angle to increase the filter media area and improve the filtration effect. The second filter intercepts small fruit peels and further breaks them up, avoiding material blockage and affecting the stable operation of the negative pressure pump. The load of the first filter unit is judged by the jet flow rate at the tail end, and it is replaced and cleaned in time to maintain a high-efficiency and stable filter media collection effect.

Detailed Implementation

[0023] Example 1:

[0024] like Figure 1-6 In the present invention, a negative pressure collection device for peanut shells includes a collection box 1. The top of the collection box 1 is connected to an air inlet pipe 2, and the bottom side of the collection box 1 is connected to an air outlet pipe 3. The air outlet pipe 3 is equipped with a negative pressure suction pump 4 and a sleeve 17. The collection box 1 is connected to an opening and closing door 6 through a hinge structure 5. The opening and closing door 6 is magnetically engaged with the collection box 1 and is equipped with a handle structure 7. The collection box 1 is equipped with multiple sets of detachable first filter material structures 13, and the two ends of the sleeve 17 are equipped with second filter material structures 18.

[0025] In a preferred embodiment, the first filter material structure 13 includes a filter plate 14, with mounting plates 15 at both ends of the filter plate 14, and a first filter screen 16 on the filter plate 14. The mounting plates 15 at both ends of the filter plate 14 are detachably and detachably fitted with mounting grooves 12 provided on the inner walls of both sides of the collection box 1.

[0026] In a preferred embodiment, the filter plate 14 is arranged obliquely inside the collection box 1, and the width of the filter plate 14 is consistent with the width of the space inside the collection box 1.

[0027] In a preferred embodiment, the collection box 1 has a sealing groove 10 at its open end, and the opening and closing door 6 has a sealing strip 11 that cooperates with the sealing groove 10.

[0028] In a preferred embodiment, the outlet end of the air outlet pipe 3 is equipped with a gas flow rate sensor 9, and the gas flow rate sensor 9 is connected to the warning light 8 installed on the opening and closing door 6 via a circuit.

[0029] In a preferred embodiment, the second filter material structure 18 is disposed inside the sleeve 17 and the distance between the second filter material structure 18 and the end of the sleeve 17 is greater than ten centimeters.

[0030] In a preferred embodiment, the second filter material structure 18 is welded and fixed to the inner wall of the sleeve 17 with an outer frame 19. The outer frame 19 is provided with a second filter screen 20. A fixed platform 21 is provided at the center of the second filter screen 20. A rotating shaft 22 is provided on the fixed platform 21. Multiple sets of blades 23 are provided on the rotating shaft 22. One of the multiple sets of blades 23 is provided with multiple sets of bristles 24 that cooperate with the second filter screen 20. The remaining blades 23 are all connected to the shredder blade 26 through a fixed arm 25.

[0031] Example 2:

[0032] like Figure 1-6 After the device is assembled, the electrical equipment such as the negative pressure air pump 4, warning light 8 and gas flow rate sensor 9 are powered on and tested to check whether the device is operating normally. The sealing performance and magnetic attraction effect of the opening and closing door 6 are tested to ensure that the device is leak-free.

[0033] Connect the device to the peanut shell generation location in the peanut processing production line, start the negative pressure suction pump 4, and the peanut shells enter the collection box 1 through the air inlet pipe 2 under the action of negative pressure suction. After being filtered by the first filter material structure 13 and the second filter material structure 18, the clean gas is discharged from the tail end of the air outlet pipe 3.

[0034] During the collection process, the gas flow rate sensor 9 monitors the gas flow rate in real time. If an abnormality occurs, the warning light 8 will light up to remind the staff to check the device.

[0035] When it is necessary to clean the collection box 1 or replace the filter media structure, turn off the negative pressure air pump 4, open the opening and closing door 6 through the handle structure 7, take out the first filter media structure 13 from the installation slot 12 for cleaning or replacement, and reinstall it into the collection box 1 after cleaning, close the opening and closing door 6, and continue to use it.

[0037] Example 3:

[0038] like Figure 1-6 The working principle of this utility model is as follows: After the negative pressure air pump 4 is started, a negative pressure is formed in the air outlet pipe 3, so that the air pressure in the collection box 1 is lower than the external air pressure. Under the action of pressure difference, peanut shells are sucked into the collection box 1 through the air inlet 2, thereby achieving efficient collection of peanut shells.

[0039] After the peanut shells enter the collection box 1, they are first filtered by the first filter screen 16 of the first filter material structure 13. Larger shell particles are intercepted on the filter plate. Due to the oblique arrangement of the filter screen 14, not only is the filtration area increased, but the intercepted shell particles also slide down the filter plate 14 to the bottom of the collection box 1 under the action of gravity, which has a certain effect of avoiding accumulation and clogging of the filter screen. At the same time, the first filter screen 16 filters the fine particles in the gas. The gas after being filtered by the first filter material structure 13 enters the sleeve 17 and undergoes secondary filtration through the second filter screen 20.

[0040] The blades 23, equipped with bristles 24 and shredder blades 26, rotate around the shaft 22 under the action of airflow. The shredder blades 23 break larger fruit peel particles into smaller particles, reducing the risk of clogging the second filter screen 20.

[0041] During rotation, the brush 24 cleans the second filter screen 20 to prevent impurities from adhering, ensuring that the gas passes smoothly through the second filter screen 20, does not accumulate in the negative pressure air pump 4, and is quickly discharged from the outlet pipe.

[0042] The opening and closing door 6 and the collection box 1 are magnetically connected, while the sealing groove 10 and the sealing strip 11 are tightly fitted to form a good sealing structure to prevent the peanut shells from leaking and external gas from entering during the collection process.

[0043] The gas flow rate sensor 9 monitors the gas flow rate at the end of the outlet pipe 3 in real time. When an abnormality such as blockage occurs inside the device, causing the gas flow rate to drop, the gas flow rate sensor 9 transmits a signal to the warning light 8, which illuminates to remind staff to check and maintain the device in a timely manner to ensure its normal operation.

[0044] The beneficial effects of this utility model are as follows: High-efficiency negative pressure collection improves the efficiency of fruit peel collection and processing. The multi-layer filter structure allows for rapid collection of fruit peels. Multiple filter media work together: the first stage primarily filters fruit peel material, requiring regular cleaning to maintain efficient and stable fruit peel collection; the second stage filters again, preventing small-sized fruit peels from directly entering the negative pressure pump and accumulating; the second stage further breaks down the fruit peels after passing through the first stage, preventing excessive residue accumulation in the negative pressure pump, which would affect equipment lifespan and reduce cleaning frequency; the obliquely arranged first-stage filter unit increases the filter media area and improves filtration efficiency; the second stage intercepts and further breaks down small-sized fruit peels, preventing material blockage and affecting the stable operation of the negative pressure pump; and the load on the first-stage filter unit is judged based on the jet flow rate at the tail end, allowing for timely replacement and cleaning to maintain efficient and stable filter media collection.
