Description

Technical Field

[0001] This utility model belongs to the technical field of ultrafine heavy calcium carbonate production equipment, and in particular relates to a powder suction device for an ultrafine heavy calcium carbonate pulverizer. Background Technology

[0002] In the production of ultrafine heavy calcium carbonate, cyclone separators are used to remove dust from the air. A cyclone separator is a device that separates gas and solid or gas and liquid based on the principle of centrifugal force. It is widely used in chemical, building materials, and environmental protection fields, and is often used in conjunction with crushers and dryers to separate solid particles or liquid droplets from airflow. Its main body is typically a combination of a cylindrical body and a conical bottom. The dust-laden airflow enters tangentially from the top of the cylinder and rotates at high speed along the cylinder wall, forming a vortex. Under centrifugal force, particles or droplets with a density greater than that of the gas are thrown against the cylinder wall and then fall down the wall to the discharge port at the conical bottom. The purified gas forms an upward airflow at the center of the vortex and is discharged from the exhaust pipe at the top of the cylinder. This equipment features a simple structure, no moving parts, convenient maintenance, and high separation efficiency. It is especially suitable for processing particles with larger diameters (usually above 5μm). It can be used as a pre-separation device to reduce the load on subsequent purification devices, or it can be used alone in scenarios where the separation accuracy requirement is not extreme, such as the preliminary separation of coarse powder in the production of heavy calcium carbonate and the pretreatment of dust in industrial exhaust gas.

[0003] Since cyclone separators rely solely on centrifugal force to separate dust from gas, they inevitably contain some residue. Connecting another type of separator not only takes up space but also doubles the cost, resulting in the relatively low practicality of conventional cyclone separators.

[0004] To address this issue, we propose a powder suction device for an ultrafine heavy calcium carbonate pulverizer. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low practicality of conventional cyclone separators, and to propose a powder suction device for an ultrafine heavy calcium carbonate pulverizer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A powder suction device for an ultrafine heavy calcium carbonate pulverizer includes a cyclone separator shell. A gas guide seat is fixedly connected to the upper part of the cyclone separator shell. A filter element is inserted inside the gas guide seat. A first flange is fixedly connected to the upper end of the gas guide seat, and a second flange is secured to the upper end of the filter element. The filter element is inserted into the gas guide seat, and then the second flange is fitted onto the filter element. Screws are passed through the second flange and the first flange and tightened to keep the filter element inside the cyclone separator shell and the gas guide seat. The filter element further filters impurities in the gas, improving the cleanliness of the filtered gas. The screws are removed, the second flange is removed, and the filter element is removed. A new filter element is installed in the gas guide seat for easy filter element replacement.

[0007] Preferably, the air guide seat includes a housing, with a docking nozzle fixedly connected to the outside of the housing, and the lower part of the housing fixedly connected to the upper part of the cyclone separator housing. An external exhaust pipe is connected via the docking nozzle.

[0008] Preferably, the filter element includes a cover that covers the housing, a bracket fixedly connected to the bottom of the cover, a filter sleeve installed at the lower part of the bracket, and the bracket inserted into the housing. Gas passes through the filter sleeve into the bracket, then through the bracket into the connector nozzle, and finally through the connector nozzle to the target pipe, facilitating the discharge of the re-filtered gas into the target exhaust pipe.

[0009] Preferably, a sealing ring is fixedly connected to the bottom of the cover, so that the sealing ring seals the housing. The sealing ring increases the sealing between the air guide seat and the filter element.

[0010] Preferably, the second flange includes a ring body with a mounting hole cut out of it. Screws are passed through the mounting hole and tightened onto the first flange to secure it.

[0011] Preferably, a slot is provided on the bottom of the ring body, into which the cover is secured. This slot increases the stability of the relative positions of the filter element and the second flange.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Insert the filter element into the air guide seat, then put the second flange on the filter element. Tighten the screws through the second flange and the first flange to keep the filter element inside the cyclone separator shell and the air guide seat. Use the filter element to filter impurities in the gas again to further improve the cleanliness of the filtered gas. Remove the screws, remove the second flange, and then remove the filter element. Install the new filter element into the air guide seat for easy filter element replacement.

[0013] 2. The gas passes through the filter sleeve and enters the bracket, then through the bracket into the docking nozzle, and finally through the docking nozzle to the target pipeline, making it convenient to discharge the re-filtered gas into the target exhaust pipeline.

[0017] like Figure 1 As shown, a powder suction device for an ultrafine heavy calcium carbonate pulverizer includes a cyclone separator shell 1. A gas guide seat 2 is fixedly connected to the upper part of the cyclone separator shell 1. A filter element 3 is inserted inside the gas guide seat 2. A first flange 5 is fixedly connected to the upper end of the gas guide seat 2, and a second flange 4 is secured to the upper end of the filter element 3. The filter element 3 is inserted into the gas guide seat 2, and then the second flange 4 is fitted onto the filter element 3. Screws are passed through the second flange 4 and the first flange 5 and tightened, so that the filter element 3 is held inside the cyclone separator shell 1 and the gas guide seat 2, thereby further filtering impurities from the gas using the filter element 3.

[0018] like Figure 1 and 2 As shown, the air guide seat 2 includes a housing 21, with a docking nozzle 22 fixedly connected to the outside of the housing 21. The lower part of the housing 21 is fixedly connected to the upper part of the cyclone separator housing 1. An exhaust pipe is connected externally via the docking nozzle 22.

[0019] like Figure 1 , 2 As shown in Figure 3, the filter element 3 includes a cover 31, which covers the housing 21. A bracket 33 is fixedly connected to the bottom of the cover 31, and a filter sleeve 34 is installed on the lower part of the bracket 33. The bracket 33 is inserted into the housing 21. Gas passes through the filter sleeve 34 into the bracket 33, then through the bracket 33 into the connector 22, and finally through the connector 22 to the target pipeline.

[0020] like Figure 1 , 2As shown in Figure 3, a sealing ring 32 is fixedly connected to the underside of the cover 31, so the sealing ring 32 seals against the housing 21. The sealing ring 32 is used to increase the sealing between the air guide seat 2 and the filter element 3.

[0021] like Figure 1 and 4 As shown, the second flange 4 includes a ring body 41, on which mounting holes 42 are cut out. Screws are passed through the mounting holes 42 and tightened to secure the first flange 5.

[0022] like Figure 1 , 3 As shown in Figure 4, a slot 43 is provided on the lower part of the ring body 41, and the cover 31 is inserted into the slot 43. By inserting the cover 31 into the slot 43, the relative position stability of the filter element 3 and the second flange 4 is increased.

[0023] Working principle: Insert the filter element 3 into the air guide seat 2, then put the second flange 4 on the filter element 3, and tighten the screws through the second flange 4 and the first flange 5 so that the filter element 3 is kept inside the cyclone separator shell 1 and the air guide seat 2, and the filter element 3 is used to filter impurities in the gas.
