Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically an environmentally friendly dust removal equipment for a concrete production line workshop. Background Technology

[0002] In concrete, sand and stone act as a skeleton and are called aggregates; cement and water form cement paste, which coats the surface of the aggregates and fills their voids. Before hardening, the cement paste acts as a lubricant, giving the mixture a certain workability and facilitating construction. Dust is generated during the production process, which requires equipment for cleaning.

[0003] Chinese Patent 202020741236.1 discloses "an autonomous dust removal device for a concrete production line". Through the cooperation of filter screen, concave plate and spring in the filtration mechanism, the filter screen is pulled and then rebounds through the spring, thereby vibrating the filter screen and cleaning it by vibration. This prevents the filter screen from becoming clogged, ensures the filtration effect and ensures normal use.

[0004] The current dust removal process requires manually pressing down the handle to rotate the eccentric gear and waiting for the spring to return. This method is complex and cumbersome, especially when frequent cleaning is needed, increasing the operator's workload and reducing ease of use. Furthermore, after dust is shaken off the filter screen, the vibration can easily cause some of the dust to drift into the equipment or workshop environment due to air turbulence, leading to secondary pollution. This not only affects air quality but also requires additional cleaning work, increasing maintenance costs. In addition, the cleaning effect of vibration is limited by the vibration intensity; it is difficult to thoroughly clean heavy dust accumulation, and filter clogging affects the equipment's dust removal efficiency, thus reducing the lifespan of the entire dust removal system. Therefore, the existing equipment suffers from operational inconvenience in its dust removal method.

[0005] In view of this, we propose an environmentally friendly dust removal equipment for concrete production line workshops. Utility Model Content

[0006] The purpose of this utility model is to provide an environmentally friendly dust removal device for concrete production line workshops, which solves the problem of inconvenient operation of existing equipment in terms of dust removal methods.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An environmentally friendly dust removal device for a concrete production line workshop includes an exhaust fan with an air outlet and an air inlet. A dust removal mechanism is installed at the air inlet, comprising a bent head tube rotatably connected to the air inlet. A filter element is rotatably connected to the inner wall of the air inlet for filtering dust. A cleaning mechanism is also installed at the air inlet to automatically clean and collect the dust collected on the filter element during the dust extraction process, preventing clogging of the filter element.

[0009] Preferably, the cleaning mechanism includes: a rear hollow block, which is fixedly connected to the air inlet; a front hollow block is fixedly connected to the inner wall of the air inlet; a collection box is bolted to the bottom of the front hollow block; the bottom of the collection box is a filter screen; the front hollow block is located on the side of the filter element closer to the disc block; the rear hollow block is located on the side of the filter element away from the disc block; a front output cavity is provided on the inner wall of the rear hollow block; an output port is provided on the inner wall of the rear hollow block; a rear receiving cavity is provided on the inner wall of the front hollow block; a conveying pipe is provided at the bottom of the rear hollow block; one end of the conveying pipe is fixedly connected to the inner wall of the rear hollow block; and a semi-circular collection frame is fixedly connected to the other end of the conveying pipe.

[0010] Preferably, the dust removal mechanism further includes a disc block, a disc block is fixedly connected to the inner wall of the bent head tube, an oblique passage pipe is provided on the inner wall of the disc block, three oblique passage pipes are provided, the three oblique passage pipes are arranged in a circumferential array, a drive shaft is provided on the outer wall of the disc block, one end of the drive shaft is fixedly connected to the disc block, and the other end of the drive shaft is fixedly connected to the filter element.

[0014] Preferably, the filter element is located between the rear hollow block and the front hollow block, and the drive shaft is rotatably connected to the inner wall of the front hollow block.

[0015] By employing the above technical solution, this utility model provides an environmentally friendly dust removal device for concrete production line workshops. It possesses at least the following beneficial effects:

[0016] 1. This utility model incorporates a cleaning mechanism. Air is discharged from the outlet, and the semi-circular collection frame collects the air from the outlet, which is then transported through a conveying pipe to the inner wall of the rear hollow block. The output port is directly opposite the rear receiving cavity, allowing it to blow dust from the filter element's surface into the rear receiving cavity. The dust then automatically enters the semi-circular collection frame through the rear receiving cavity for collection. This prevents filter element clogging, maintains its optimal filtration effect, and allows for automatic cleaning of the filter element, reducing the need for manual intervention and frequent cleaning, thus lowering the labor intensity and maintenance costs for operators.

[0017] 2. This utility model incorporates a dust removal mechanism. Air from the concrete production line workshop enters the air inlet through a bent head pipe. As the air passes through the oblique through-pipe, it causes the oblique through-pipe to drive the disc block to rotate and suck up dust. This rotation increases the kinetic energy of the airflow and generates a certain vortex effect, which helps to adsorb dust and improve dust removal efficiency. The disc block drives the bent head pipe to suck up dust, and the sucked-up dust gathers on the filter element.

[0018] 3. This utility model incorporates a dust removal mechanism. The disc block drives the filter element to rotate via a transmission shaft, preventing the filter element from becoming clogged due to dust accumulation and ensuring unobstructed airflow at the air inlet, thereby improving the ventilation and dust removal efficiency of the equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 7 As shown, this utility model provides a technical solution: an environmentally friendly dust removal device for a concrete production line workshop, including an exhaust fan 1, which is equipped with an air outlet 2 and an air inlet 3. The air outlet 2 is used to discharge air or gas, and is usually the outlet for air flow inside the equipment; the air inlet 3 is used to introduce external air or gas, and is usually the inlet for air flow inside the equipment. A dust removal mechanism 4 is provided on the air inlet 3, which includes a bent head pipe 41 rotatably connected to the air inlet 3. A filter element 42 is rotatably connected to the inner wall of the air inlet 3. A cleaning mechanism 5 is provided on the air inlet 3, which includes a rear hollow block 51 fixedly connected to the air inlet 3. Above, a front hollow block 52 is fixedly connected to the inner wall of the air inlet 3. A collection box 53 is bolted to the bottom of the front hollow block 52. The bottom of the collection box 53 is a filter screen. The front hollow block 52 is located on the side of the filter element 42 close to the disc block 43. The rear hollow block 51 is located on the side of the filter element 42 away from the disc block 43. A front output cavity 54 is provided on the inner wall of the rear hollow block 51. An output port 55 is provided on the inner wall of the rear hollow block 51. A rear receiving cavity 56 is provided on the inner wall of the front hollow block 52. A conveying pipe 57 is provided at the bottom of the rear hollow block 51. One end of the conveying pipe 57 is fixedly connected to the inner wall of the rear hollow block 51. A semi-circular collection frame 58 is fixedly connected to the other end of the conveying pipe 57.

[0030] The dust removal mechanism 4 also includes a disc block 43. The disc block 43 is fixedly connected to the inner wall of the bent head tube 41. An inclined passage pipe 44 is provided on the inner wall of the disc block 43. There are three inclined passage pipes 44 arranged in a circumferential array. When outside air enters the air inlet 3 through the bent head tube 41, the air passes through the inclined passage pipes 44, causing the inclined passage pipes 44 to drive the disc block 43 to rotate and suck up dust. This rotation can increase the kinetic energy of the airflow and generate a certain vortex effect, which helps to adsorb dust and improve dust removal efficiency. The disc block 43 drives the bent head tube 41 to suck up dust, and the sucked-up dust gathers on the filter element. On the disc block 43, a drive shaft 45 is provided on the outer wall. One end of the drive shaft 45 is fixedly connected to the disc block 43, and the other end of the drive shaft 45 is fixedly connected to the filter element 42. When the disc block 43 rotates, the disc block 43 drives the filter element 42 to rotate through the drive shaft 45, preventing the filter element 42 from being blocked by dust accumulation, ensuring that the air flow of the air inlet 3 is not obstructed, thereby improving the ventilation and dust removal efficiency of the equipment. The outer wall of the conveying pipe 57 is fixedly connected to the inner wall of the air outlet 2 for fixing the conveying pipe 57. The semi-circular collection frame 58 is located on the inner wall of the air outlet 2 and is used to collect the air blown out of the air outlet 2.

[0031] The inner wall of the semicircular collection frame 58 is connected to the inner wall of the rear hollow block 51 through the conveying pipe 57, so that the air collected by the semicircular collection frame 58 is delivered to the inner wall of the rear hollow block 51 through the conveying pipe 57. The output port 55 is directly opposite to the rear receiving cavity 56. When the front output cavity 54 in the rear hollow block 51 blows out air through the output port 55, the air blown out of the output port 55 is opposite to the air intake in the air inlet 3. However, due to the obstruction of the front hollow block 52, the output port 55 can blow the dust on the surface of the filter element 42 into the rear receiving cavity 56. The dust then enters the semicircular collection frame 58 through the rear receiving cavity 56 for collection. The filter element 42 is located between the rear hollow block 51 and the front hollow block 52. The drive shaft 45 is rotatably connected to the inner wall of the front hollow block 52.

[0032] When using the environmentally friendly dust removal equipment for a concrete production line workshop, the exhaust fan 1 is turned on, and the exhaust fan 1 drives air to enter through the air inlet 3 and exit through the air outlet 2. This allows the air in the concrete production line workshop to enter the air inlet 3 through the bent head pipe 41. When the air passes through the oblique through pipe 44, the oblique through pipe 44 drives the disc block 43 to rotate and suck up dust. This rotation can increase the kinetic energy of the airflow and generate a certain vortex effect, which helps to adsorb dust and improve dust removal efficiency. The disc block 43 drives the bent head pipe 41 to suck up dust, and the sucked-up dust is collected on the filter element 42.

[0033] When the disc block 43 rotates, the disc block 43 drives the filter element 42 to rotate through the transmission shaft 45, preventing the filter element 42 from being blocked by dust accumulation, ensuring that the airflow of the air inlet 3 is unobstructed, thereby improving the ventilation and dust removal efficiency of the equipment.

[0034] Air is discharged from the outlet 2, causing the semi-circular collection frame 58 to collect the air from the outlet 2 and transport it through the delivery pipe 57 to the inner wall of the rear hollow block 51. The output port 55 is directly opposite the rear receiving cavity 56. When the front output cavity 54 in the rear hollow block 51 blows air out through the output port 55, the air blown out by the output port 55 is opposite to the air entering the inlet 3. However, due to the obstruction of the front hollow block 52, the output port 55 can blow the dust on the surface of the filter element 42 into the rear receiving cavity 56. The dust then enters the semi-circular collection frame 58 through the rear receiving cavity 56 for automatic collection. This avoids clogging of the filter element 42, maintains its good filtration effect, and allows the filter element 42 to be cleaned automatically, reducing the need for manual intervention and frequent cleaning, thus reducing the labor intensity and maintenance costs of operators.
