Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a bag filter device for separating coarse sand. Background Technology

[0002] A bag filter is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the bag filter, larger and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is trapped, thus purifying the gas.

[0003] As baghouse dust collectors are used for a longer period of time, the dust layer on the surface of the filter bags will gradually thicken, leading to increased filtration resistance and decreased dust removal efficiency. Regular replacement of the internal dust collection bags is required, which requires manual removal of the dust collection bags, which is time-consuming, labor-intensive, and also affects the health of the workers. Utility Model Content

[0004] The purpose of this invention is to provide a bag filter dust collector device for separating coarse sand, which can effectively remove the dust accumulated on the surface of the filter bag, ensure the permeability of the filter bag, and significantly improve the dust removal efficiency.

[0005] To achieve the above objectives, a baghouse dust collector device for separating coarse sand is provided, comprising: a dust collector body, a dust hopper fixedly connected to the lower end of the dust collector body, a collection box installed at the lower end of the dust hopper, an installation frame installed inside the dust collector body, a plurality of filter bags installed below the installation frame, a spring fixedly connected to the end of each filter bag away from the installation frame, a support frame provided inside the dust collector body and below the filter bags, a baffle provided on one side of the support frame, and a dust removal unit provided on one side of the dust collector body.

[0006] According to the aforementioned bag filter device for separating coarse sand, the dust removal unit includes a mounting plate fixedly connected to one side of the dust collector body. A motor is fixedly connected to the upper end of the mounting plate, and a rotating shaft is fixedly connected to the output end of the motor. Multiple paddles are fixedly connected to the rotating shaft through one end of the outer wall of the dust collector body.

[0007] According to the bag filter device for separating coarse sand, a plurality of the paddles are located on one side of the baffle, and the ends of the plurality of paddles away from the rotating shaft are in contact with the baffle.

[0008] According to the aforementioned bag filter device for separating coarse sand, the inner wall of the dust collector body is provided with two sliding grooves, which are vertically arranged on both sides of the support frame.

[0009] According to the bag filter device for separating coarse sand, guide blocks are fixedly connected to both sides of the support frame, and the guide blocks are adapted to and slidably connected to the inner wall of the chute.

[0010] According to the aforementioned bag filter device for separating coarse sand, an air inlet is installed on one side of the dust collector body, and an air outlet is installed at the upper end of the dust collector body.

[0011] According to the bag filter device for separating coarse sand, the two ends of the dust collector body are fixedly connected to the brackets, and the bottom ends of the two brackets are fixedly connected to the base plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with existing technologies, the motor drives the rotating shaft to rotate the paddle, and the paddle strikes the baffle, causing the support frame to vibrate. This vibration method can effectively remove the dust accumulated on the surface of the filter bag.

[0014] 2. Compared with existing technologies, the deformation force of the spring enhances the vibration effect, making it easier to shake off the dust on the filter bag, ensuring the permeability of the filter bag, and thus significantly improving the dust removal efficiency.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides a bag filter device for separating coarse sand, comprising: a dust collector body 1, a dust hopper 2 fixedly connected to the lower end of the dust collector body 1, a collection box 3 installed at the lower end of the dust hopper 2, an installation frame 4 installed inside the dust collector body 1, multiple filter bags 5 installed below the installation frame 4, and a spring 6 fixedly connected to the end of each filter bag 5 away from the installation frame 4, a support frame 7 provided inside the dust collector body 1 and below the filter bags 5, a baffle 8 provided on one side of the support frame 7, and a dust removal unit 9 provided on one side of the dust collector body 1.

[0024] The dust removal unit 9 includes a mounting plate 901 fixedly connected to one side of the dust collector body 1. A motor 902 is fixedly connected to the upper end of the mounting plate 901, and a rotating shaft 903 is fixedly connected to the output end of the motor 902. Multiple paddles 904 are fixedly connected to the rotating shaft 903 through one end of the outer wall of the dust collector body 1. The dust removal unit 9 can clean the dust adsorbed on the surface of the filter bag 5.

[0025] Multiple paddles 904 are located on one side of the baffle 8, with the ends of the paddles 904 away from the rotating shaft 903 in contact with the baffle 8. The support frame 7 vibrates by rotating and striking the baffle 8 through the paddles 904.

[0026] The inner wall of the dust collector body 1 is provided with two sliding grooves 10, which are vertically arranged on both sides of the support frame 7.

[0027] Guide blocks 701 are fixedly connected to both sides of the support frame 7. The guide blocks 701 are adapted to and slidably connected to the inner wall of the slide groove 10. The support frame 7 can slide along the direction of the slide groove 10 through the guide blocks 701.

[0028] An air inlet 11 is installed on one side of the dust collector body 1, and an air outlet 12 is installed at the upper end of the dust collector body 1. Dust-laden gas enters the dust collector body 1 through the air inlet 11, and filtered gas is discharged from the dust collector body 1 through the air outlet 12.

[0029] The dust collector body 1 is fixedly connected to both ends of the support brackets 13, and the bottom ends of the two support brackets 13 are fixedly connected to the base plate 14. The support brackets 13 and the base plate 14 improve the stability of the dust collector body 1 during operation.

[0030] Working principle: During use, dust-laden gas enters the dust collector body 1 through the air inlet 11. It filters fine dust in the airflow through multiple filter bags 5 and captures and separates coarse sand or large dust particles in the airflow. After long-term use, the dust on the surface of the filter bags 5 gradually increases, which will affect the dust removal efficiency. At this time, the motor 902 can be started to drive the rotating shaft 90 to drive multiple paddles 904 to rotate. During the rotation of the paddles 904, they come into contact with the baffle 8 and strike each other. Under the action of the deformation force of the spring 6, the vibration effect of the filter bags 5 is enhanced, further removing the dust on the surface of the filter bags 5. At the same time, the dust that is shaken off falls into the ash hopper 2 under the action of gravity and is collected and processed through the collection box 3.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
