Description

Technical Field

[0001] This utility model relates to the field of inclined cartridge dust removal technology, specifically to an inclined cartridge dust removal device that facilitates quantitative ash discharge. Background Technology

[0002] The inclined cartridge dust collector is composed of multiple inclined cartridges. The inclined insertion method makes it easier to install and replace the cartridges, while also increasing the contact area with the exhaust gas and better aligning with the direction of the back-blowing mechanism, thus improving the efficiency of dust removal during back-blowing. Traditional dust collectors require manual operation for the regular cleaning and emptying of the bottom ash cylinder, resulting in low ash unloading efficiency.

[0003] Existing inclined cartridge dust collectors require manual intervention or operation for ash removal. For example, the offline cleaning inclined three-stage cartridge dust collector disclosed in CN210674579U includes a clean air chamber, a filter chamber, an ash hopper, and a pulse cleaning device. Two vertical partitions are installed in the clean air chamber, with a width ≥765mm. N horizontal inclined partitions are symmetrically arranged on both sides of the two vertical partitions, dividing the clean air chamber into n branch clean air chambers and a central channel. The central channel is connected to the clean air outlet pipe. N branch clean air inlets, corresponding to the n branch clean air chambers, are installed on the two vertical partitions. N branch pneumatic valves, corresponding to the n branch clean air inlets, are installed in the n branch clean air chambers. A dust-gas separation device is vertically installed in the filter chamber, with several sets of filter cartridges symmetrically arranged on both sides of the dust-gas separation device. This invention increases the effective usable area of ​​the filter cartridge assembly from ≤65% in traditional inclined cartridge dust collectors to 100%, improves filtration accuracy by 0.013%-3.0%, and doubles the service life of each filter cartridge. However, the emptying and cleaning of the ash hopper in this solution requires manual operation, resulting in low ash unloading efficiency.

[0004] Therefore, it is necessary to invent a dust removal device with a slanted filter cartridge that facilitates quantitative ash discharge to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a slanted cartridge dust collector that facilitates quantitative ash discharge, thereby solving the problem that the ash discharge operation of slanted cartridge dust collectors in the technology requires human intervention and cannot discharge ash intelligently.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dust collector with a tilted filter cartridge for easy quantitative ash discharge includes a main body, an exhaust gas connection end, and tilted filter cartridges. The exhaust gas connection end is located on the top of the main body. Multiple tilted filter cartridges can be tilted and inserted into the main body. A dust baffle is located directly above one end of each filter cartridge. A back-blowing connection port is located on the other side of the main body opposite the dust baffle. The back-blowing connection port and the back-blowing mechanism are connected by a pipe. A dust collection box is installed inside the main body. A cylinder is connected to one side of the dust collection box. The cylinder's push shaft extends into the dust collection box. A weight sensor is installed at the bottom of the dust collection box. An electrical signal is transmitted between the weight sensor and a switch on the cylinder.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] 1. This utility model detects weight by installing a cylinder on the ash collection box and a weight sensor at the bottom. When the weight of the dust collected in the ash collection box reaches the preset value of the weight sensor, a start signal is sent to the cylinder to start the cylinder and push the push plate in the ash collection box to push out and dump the dust in the ash collection box. When the cylinder resets, the push plate and the movable baffle will also reset, making the whole ash unloading process intelligent.

[0010] 2. This utility model, through the push plate installed inside the ash collection box and the special structure of the push plate, can push out and dump the dust inside the ash collection box, while using multiple rotating brush sleeves to clean the bottom of the ash collection box, and using multiple shovel-shaped sleeves and push plates to shovel and scrape the dust on the bottom of the ash collection plate, thereby improving cleaning efficiency and ensuring the cleanliness of the ash collection box.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figures 1-5 The dust collector shown is a slanted filter cartridge dust collector for easy quantitative ash discharge. It includes a dust collector body 1, an exhaust gas connection end 2, and slanted filter cartridges 3. The exhaust gas connection end 2 is located on the top of the dust collector body 1. Multiple slanted filter cartridges 3 can be inserted into the dust collector body 1 at an angle. A dust baffle plate 4 is set directly above one end of the multiple slanted filter cartridges 3. A back-blowing connection port 5 is located on the other side of the dust collector body 1 opposite to the dust baffle plate 4. The back-blowing connection port 5 and the back-blowing mechanism 6 are connected by a pipe. A dust collection box 8 is installed inside the dust collector body 1. A cylinder 7 is connected to one side of the dust collection box 8. The push shaft of the cylinder 7 extends into the dust collection box 8. A weight sensor 9 is installed at the bottom of the dust collection box 8. The weight sensor 9 and the switch on the cylinder 7 are controlled by a PLC to transmit electrical signals.

[0020] When the weight sensor 9 senses a weight that matches the preset value, it will send a start signal to the cylinder 7, which will push the pushing mechanism in the dust collection box 8 to push out and empty the dust in the dust collection box 8.

[0021] A rotating shaft 801 is installed on the ash collection box 8. A movable baffle 802 is rotatably connected to the rotating shaft 801. A connecting rod 803 is hinged to the movable baffle 802. The connecting rod 803 can be completely retracted into the slide groove 804. A slider structure is hinged to one end of the connecting rod 803 and can slide with the slide groove 804. The connecting rod 803, the slider structure, and the slide groove 804 form a hovering limiter. This hovering limiter is a known technology application and can achieve the hovering of the movable baffle 802 at any position. The slide groove 804 is opened on the push plate 805. The push plate 805 can slide within the ash collection box 8. The cross-section of the push plate 805 is U-shaped. The bottom of the push plate 805 has two rectangular openings. Push plates 806 are installed at adjacent positions of the two rectangular openings. The distribution direction of the push plates 806 is perpendicular to the movement direction of the push plate 805. The height of the push plates 806 is twice the thickness of the push plate 805.

[0022] The push plate 805 inside the dust collection box 8 is pushed by the cylinder 7, continuously opening the movable baffle 802 without it detaching from the push plate 805. This also ensures that when the cylinder 7 is reset, the movable baffle 802 returns to its position flush with the side wall of the dust collection box 8. A vertical side plate on the push plate 805, which is connected to the shaft of the cylinder 7, further pushes the dust. When the rectangular opening adjacent to this vertical side plate moves beyond the bottom lower boundary of the dust collection box 8, the dust can be discharged from this rectangular opening, achieving a secondary dust removal effect.

[0023] The push plate 806 is fixedly connected to the push plate 805. The push plate 806 is adjacent to but does not contact the brush sleeve 807. A shovel-shaped sleeve 808 is coaxially connected to the brush sleeve 807. Multiple brush sleeves 807 and shovel-shaped sleeves 808 are provided, and the number of shovel-shaped sleeves 808 and brush sleeves 807 is the same. The brush sleeves 807 and shovel-shaped sleeves 808 are spaced apart. Multiple brush sleeves 807 can contact the bottom plate of the ash collection box 8, and the bottom of multiple brush sleeves 807 also contacts the bottom plate of the ash collection box 8. Some brush sleeves 807 do not rotate, while the rest can rotate. As the push plate 805 is continuously pushed out of the ash collection box 8, the dust is pushed out and dumped. Simultaneously, the multiple brush sleeves 807, shovel-shaped sleeves 808, and the push plate 806, which extends above the push plate 805, clean the bottom plate of the ash collection box 8.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual appendix Figures 1-3 First, the exhaust gas is connected to the main body 1 of the dust removal equipment through the exhaust gas connection end 2. The exhaust gas is filtered by multiple inclined filter barrels 3. Then, the dust absorbed in the main body 1 of the dust removal equipment, i.e. the dust in the multiple inclined filter barrels 3, is cleaned by the external back-blowing mechanism 6 and back-blowing connection port 5. The dust blown by the back-blowing mechanism 6 is collected in the dust collection box 8. When the weight of the dust in the dust collection box 8 reaches the preset value, an electrical signal is sent to the cylinder 7 to start the cylinder 7 and begin to push the push plate 805.

[0026] Refer to the instruction manual appendix Figures 3-5 During the pushing process of the push plate 805, the movable baffle 802 is continuously opened. Under the action of the slide groove 804 and the connecting rod 803, the movable baffle 802 will not fall off during the continuous pushing process, and the horizontal movement of the push plate 805 can be guaranteed until all the dust at the bottom of the dust collection box 8 is pushed out. During the horizontal outward pushing process of the push plate 805, the push plate 806 can initially clean the dust on the bottom plate of the dust collection box 8. The bottom plate of the dust collection box 8 is then cleaned a second time by the continuously rotating brush sleeve 807 and the non-rotating shovel sleeve 808 to ensure the cleanliness of the bottom plate of the dust collection box 8.
