Description

Technical Field

[0001] This utility model relates to the field of dust capture technology, and in particular to an environmentally friendly workshop dust capture device. Background Technology

[0002] Grain dust originates from grain processing, transportation, and storage. During processing, operations such as grinding and screening break grains into tiny particles that form dust, such as during wheat milling. Equipment vibration, ventilation, and handling during storage also generate dust. The particle size is mostly between a few micrometers and tens of micrometers. It has a large specific surface area and is easily suspended. Grain dust is highly hazardous, as it can damage the health of workers, easily cause explosions that threaten enterprise safety, and also cause air pollution.

[0003] In a baghouse dust collector for grain processing, dust-laden gas enters the baghouse dust collector under the action of a fan. The gas first settles in the ash hopper due to inertia and gravity, and then the gas passes through the filter bags, which are usually made of polyester fiber. The dust is blocked outside the filter bags, and the air passes through the filter bags. As filtration continues, a dust layer forms on the surface of the filter bags, which can improve the filtration effect and intercept even finer dust. Finally, the purified air is discharged, completing the dust removal process.

[0004] During the dust removal process, static electricity is easily generated due to factors such as friction between dust particles and filter bags and airflow. Since most grain dust is flammable, when static electricity accumulates to a certain level, it may cause an explosion, posing a serious threat to production safety. In addition, if the filter bags are in a humid environment, moisture will affect the air permeability of the bags and their ability to adsorb dust, resulting in a decrease in filtration efficiency and leaving the exhaust gas still containing a lot of dust. Therefore, an environmentally friendly workshop dust capture device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly workshop dust capture device, which aims to improve the existing technology's problems of dust friction with the filter bag, static electricity generated by airflow, flammable grain dust and potential explosion due to static electricity, and reduced filtration efficiency when the filter bag is damp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly workshop dust capture device, comprising a box, with columns equidistantly arranged at the four corners of the box, the left side of the box connected to a dust suction port via a pipe, a bag assembly inside the box, a back-blowing mechanism at the top of the box, two collection hoppers equidistantly arranged at the bottom of the box, each collection hopper having a discharge mechanism at its bottom, a ventilation assembly on the right side of the box, and an electrostatic assembly on the left side of the box;

[0007] The electrostatic component includes an electrostatic column, which is located on the left side of the housing. One end of the electrostatic column is provided with an electrostatic tube, and the other end of the electrostatic tube is respectively located on the outside of the housing and the dust inlet.

[0008] As a further description of the above technical solution: the back-blowing mechanism includes an air pump, which is located on the front side of the housing. The output end of the air pump is connected to multiple nozzles through a pipe, and a heating component is provided on the outside of the pipe. Multiple nozzles are equidistantly arranged on the lower side of each nozzle, and each nozzle penetrates the top of the housing.

[0009] As a further description of the above technical solution: the bag assembly includes a mounting plate, all of which are disposed inside the box, and multiple bags are equidistantly arranged at the bottom of each mounting plate;

[0010] As a further description of the above technical solution: the exhaust assembly includes a fan, the fan is located on the right side of the housing, the input end of the fan is connected to the air collection hopper through a pipe, and the air collection hopper is located on the right side of the housing, and the output end of the fan is provided with an exhaust pipe;

[0011] As a further description of the above technical solution: the heating component includes a cylinder, which is disposed on a pipe connecting an air pump and multiple nozzles, and multiple heating wires are evenly arranged inside the cylinder;

[0012] As a further description of the above technical solution: the feeding mechanism includes square tubes, all of which are arranged on the lower side of the collecting hopper, and a motor is arranged on the front side of each square tube, with a plate arranged at the output end of the motor;

[0013] As a further description of the above technical solution: each of the columns is provided with a fixing plate at its bottom, and fixing bolts are provided at equal intervals at the four corners of the fixing plate;

[0014] As a further description of the above technical solution: a foreign object screen is provided on the outside of the suction port.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, an effective static electricity elimination defense line is formed by the static electricity column and the static electricity tube. One end of the static electricity tube is connected to the static electricity column, and the other end extends to the key parts, such as the outside of the box and the dust suction port. When dust is collected, the static electricity generated by various frictions can be neutralized in time. In places such as grain processing where flammable dust is easily generated, the accumulation of static electricity may cause a catastrophic explosion. This effectively avoids such danger, ensures the normal operation of equipment and the safety of personnel, and ensures the stability of the entire production environment.

[0017] 2. In this utility model, through the coordinated operation of the heating component and the air pump in the back-blowing mechanism, the air pump, as a power source, provides energy for the airflow, enabling the airflow to be transmitted through the pipeline. The heating wire inside the cylinder heats the airflow, and the hot airflow is sprayed onto the filter bag through the spray pipe and nozzle. When the filter bag gets damp, this drying method can quickly remove the moisture, restore the air permeability and dust filtration capacity of the filter bag, ensure the filter bag to work continuously and efficiently, thereby maintaining the stable operation of the entire dust removal system, reducing maintenance costs and increasing the service life of the equipment.

The output end of the fan 11 is provided with an exhaust pipe 12, which is used to discharge the treated gas.

[0029] An electrostatic component is installed on the left side of the housing 1. The electrostatic component is used to eliminate static electricity in the system and prevent static electricity accumulation from causing danger. The electrostatic component includes an electrostatic column 7, which is the core component of the electrostatic treatment. The electrostatic column 7 is located on the left side of the housing 1.

[0032] Working principle: First, place the housing 1 with the upright column 2 in the area where dust removal is needed, and fix it with the fixing plate 15 and fixing bolts 16 at the bottom of the upright column 2. Place the fan 11 in a suitable position, and connect the input end of the fan 11 to the air collection hopper 10 of the housing 1 with a pipe.

Install the electrostatic column 7, and connect one end of the electrostatic tube 6 to the input end of the electrostatic column 7, with multiple tubes extending from the other end, which are respectively connected to the suction port 5, the housing 1, and areas prone to static electricity. After starting the fan 11, the dust in the warehouse or workshop is sucked into the housing 1 through the suction port 5. The particulate dust settles in the collection hopper 8 due to inertia and gravity. Gas passes through filter bag 14, dust is blocked by filter bag 14, and purified air is discharged, completing the dust removal. The static electricity generated during the dust collection process is eliminated by the electrostatic tube 6 and electrostatic column 7, which can neutralize the dust charge and prevent static electricity accumulation. This is of great significance for keeping the equipment clean and preventing explosions. When the collection hopper 8 collects a certain amount of dust, the motor 902 is started to open the plate 903 to process the dust. After the filter bag 14 has been used for a period of time, a large amount of dust will be attached to its surface, affecting the filtration effect. At this time, the air pump 301 is started to back-blow the filter bag 14, so that the dust falls into the collection hopper 8. If the filter bag 14 is damp, the heating wire 304 can be used in conjunction with the air pump 301 to dry the filter bag 14 to avoid moisture affecting air filtration.
