Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification device for a factory workshop. Background Art

[0002] When working in factory workshops and other places, workers will bring in dust from the outside when entering the room. At the same time, the entry of dust will affect the work and the quality of the products produced. Some workshops will produce toxic gases during work, which will have a physical impact on the workers, and the direct discharge will affect the environment. Therefore, factory workshops are usually equipped with air purifiers to treat the air accordingly. Air purifiers usually have multi-layer filter elements. The multi-layer filter elements can be used to treat dust and toxic gases in the air accordingly. Usually, the outer layer of the multi-layer filter element is a cylindrical filter, which is used to filter impurity particles in the air. It only needs to remove the impurities without replacement. The inner layer is used to adsorb and purify toxic gases (usually activated carbon filter elements, etc.), which need to be replaced regularly. The maintenance time of the above filter elements is different, and the maintenance method is also different. Nowadays, they are usually taken out for processing. When only the inner filter element needs to be replaced, the above removal method must be disassembled after the filter element is taken out as a whole to remove the inner filter element inside. This will affect the replacement efficiency of the inner filter element, and there are limitations in its use. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-7 The utility model discloses an air purification device for a factory workshop, comprising a purifier body 1, the purifier body 1 comprising a lower seat body 11, an upper seat body 12 rotatably mounted on the lower seat body 11 and interconnected, a multi-layer filter element 16 arranged in the lower seat body 11 and an air suction device installed on the upper seat body 12, both the lower seat body 11 and the upper seat body 12 are provided with air inlets and outlets, the air suction device is used to suck air from the lower seat body 11 into the multi-layer filter element 16, the multi-layer filter element 16 is composed of a plurality of cylindrical filter elements which are sequentially sleeved, and is used to process particulate impurities and toxic gases in the air, and after the air purification is completed, it is discharged along the discharge end of the air suction device toward the air inlet and outlet on the upper seat body 12, and finally discharged from the entire device.

[0026] In one embodiment, there are gaps of the same length between the multiple cylindrical filter elements in the multi-layer filter element 16, and a linkage rod 3 is detachably provided on the upper seat body 12. The linkage rod 3 is located at the axis of the multi-layer filter element 16, and the other end of the linkage rod 3 away from the upper seat body 12 extends to the bottom of the multi-layer filter element 16, and a removal device is provided at this end of the linkage rod 3. The removal device is used to adjust the lateral length when the linkage rod 3 rotates, and is inserted into the gap of the corresponding cylindrical filter element.

[0027] In a specific implementation, when it is necessary to take out the inner filter element in the multi-layer filter element 16, the upper seat body 12 is rotated first. At this time, the linkage rod 3 will rotate synchronously, thereby changing the lateral length of the removal device. When its length is adjusted to between the corresponding two cylindrical filter elements, it can be vertically inserted into the gap. At this time, the upper seat body 12 is lifted upward to take out the cylindrical filter element on the inner side from the lower seat body 11. Therefore, it is not necessary to take out all the cylindrical filter elements in the multi-layer filter element 16 at the same time, but only the cylindrical filter elements that need to be maintained and replaced can be taken out, thereby realizing the targeted removal of the corresponding filter elements according to the different filter elements that need to be maintained, so as to improve the maintenance efficiency.

[0028] In one embodiment, the purifier body 1 also includes a base 13 installed at the bottom of the lower seat body 11, the base 13 includes a seat plate and a universal wheel rotatably installed at the bottom of the seat plate, the suction device includes a fan blade 15 rotatably arranged in the upper seat body 12 and a power device installed on the upper seat body 12, the power device can be a motor 14, the rotating shaft of the motor 14 is connected to the center of the fan blade 15, and is used to drive the fan blade 15 to rotate, and the fan blade 15 is located above the multi-layer filter element 16.

[0029] With such a design, when the motor 14 is started, the fan blades 15 can rotate, thereby drawing air into the multi-layer filter element 16, and the air is discharged from above the multi-layer filter element 16 after purification. The setting of the universal wheel can facilitate the flexible movement of the device to the corresponding place for placement, and in actual situations, brake pads can be installed on the universal wheel. After the staff manually operates the brake pads to brake the universal wheel, the device can be stably placed and used in the corresponding place.

[0030] In one embodiment, the removal device includes a gear 5 installed at the bottom of the linkage rod 3, a mounting ring 4 rotatably mounted on the linkage rod 3, a rack 6 arranged on both sides of the gear 5 in a relative manner and meshing with the rack 6, and a sharp tooth block 9 slidably inserted into the rack 6. An L-shaped connecting frame is provided on the mounting ring 4, and a sliding groove 7 is provided on the rack 6 along its length direction. The connecting frame can be slidably inserted into the sliding groove 7. A base 8 in contact with the multi-layer filter element 16 is provided on the inner bottom wall of the lower seat body 11. The base 8 includes a placement seat 81 and two guide grooves 82 opened in the placement seat 81. The rack 6 can be slidably inserted in the guide groove 82, and a spring connected to the rack 6 is installed on the sharp tooth block 9.

[0031] In the specific implementation, when the operator rotates the upper seat body 12, the linkage rod 3 will rotate synchronously, and the gear 5 will rotate synchronously with the linkage rod 3, and drive each rack 6 to slide in the corresponding guide groove 82, and the two racks 6 will approach and move away from each other, thereby changing their spacing, and the sharp tooth block 9 will move synchronously to between the corresponding two cylindrical filter elements in the multi-layer filter element 16. During the movement, the inclined surface of the sharp tooth block 9 will first contact the bottom wall of the multi-layer filter element 16, and it will retract into the rack 6. When it moves to the gap where there is no obstruction above it, the sharp tooth block 9 will be inserted into the corresponding gap. After the staff senses the movement of the sharp tooth block 9, they can pull the upper seat body 12 upward, the rack 6 and the sharp tooth block 9 move synchronously and take the cylindrical filter element out of the lower seat body 11, and the rack 6 can take out different numbers of cylindrical filter elements according to different moving positions, and the two sides of the sharp tooth block 9 are inclined, so the sharp tooth block 9 will not be stuck by the multi-layer filter element 16 when the rack 6 moves horizontally.

[0032] In one embodiment, a plurality of annular limiting grooves 83 are formed on the placement seat 81 , and a plurality of cylindrical filter elements in the multi-layer filter element 16 are inserted into the corresponding limiting grooves 83 in sequence.

[0033] Such a design can ensure that the spacing between the multiple cylindrical filter elements in the multi-layer filter element 16 does not change, thereby facilitating the insertion and use of the sharp tooth block 9.

[0035] With such a design, when the corresponding cylindrical filter element in the multi-layer filter element 16 is taken out from the lower seat body 11, the combined length of the rod body 31 and the sleeve body 33 can be lengthened. At this time, the distance between the cylindrical filter element and the upper seat body 12 is enlarged, thereby facilitating the staff's hands to approach and contact the disassembly component 2. Subsequently, after the disassembly component 2 is removed from the upper seat body 12, the cylindrical filter element can be removed upward from the removal device.

[0036] In one embodiment, the disassembly component 2 includes an assembly plate 21 and a latch 22 slidably inserted on both sides of the assembly plate 21, a spring in contact with the latch 22 is installed in the assembly plate 21, and the plug plate 32 is inserted into the assembly plate 21. The latch 22 is L-shaped, one end of which extends downward to the outside of the assembly plate 21, and the other end of which is inserted into the upper seat 12.

[0037] With this design, the staff can touch the downward vertical end of the pin 22 and pull it toward the side close to the center of the assembly plate 21. At this time, the other end of the pin 22 will gradually disengage from the upper seat 12, so that the disassembly component 2 can be effectively removed from the assembly plate 21.
