Description

A noise reduction and dust removal device

technical field

The utility model relates to the field of industrial cleaning equipment, in particular to a noise reduction and dust removal device.

Background technique

In the existing industrial production, such as in the motor production workshop, when coating the motor stator, the coating machine will suck away a lot of granular coating powder attached to the surface of the stator during the operation through the exhaust device, and the dust will pass through the exhaust. The wind device enters the atmosphere, and the outlet of the exhaust device has not been purified, which has a great impact on the nearby air quality; and there is also the problem of high noise at the vent, which affects the lives of nearby residents. However, the existing dust removal and noise reduction equipment is sold in complete sets, so the price is relatively expensive and the function is single. For a specific factory, because there are few types of pollution sources of exhaust gas pollution caused by its production, it is necessary to purchase a complete set of dust removal equipment and Noise reduction equipment, expensive equipment is a burden for enterprises, and the utilization rate of equipment is low, energy consumption is high, which increases the cost of production, and for small and medium-sized enterprises or small workshops, it is impossible to use a complete set of dust removal equipment Dust. Considering the cost of equipment, some manufacturers choose to directly discharge the air in the production workshop in order to save the cost of purchasing dust removal equipment, but such treatment is extremely harmful to the environment.

Utility model content

The purpose of the utility model is to provide a simple and efficient noise reduction and dust removal device.

The purpose of this utility model is achieved by the following means: a noise reduction and dust removal device, the device includes a box placed at the end of the exhaust device, and the two ends of the box are respectively provided with an air inlet and an air outlet; The bottom of the box is axially provided with several ash hopper openings, and dust collection bags are installed on the ash hopper openings; at least two dust-absorbing panels are installed radially in the box, and a sound-absorbing layer is provided on the inner wall of the box.

As a further optimization of this solution, the sound-absorbing layer is a mineral wool sound-absorbing board or a sound-absorbing material coating.

As a further optimization of this solution, the box is cylindrical.

As a further optimization of the solution, the dust collection bags are provided with several filter holes, and the filter holes of the dust collection bags distributed sequentially along the airflow direction are successively reduced in diameter.

As a further optimization of this solution, the dust collection bag is a dust collection cloth bag or a PVC dust collection bag.

Compared with the prior art, the beneficial effect of a noise reduction and dust removal device of the present invention is that the present invention uses the principle of gravity sedimentation to remove dust naturally, and also reduces noise through porous shunting, has simple structure, low preparation cost, convenient installation and replacement, and is suitable for Wide range, good noise reduction and dust removal effect, long service life.

detailed description

As shown in Figure 1, the utility model is a noise reduction and dust removal device, which includes a cylindrical box 1 placed at the end of the exhaust device, and the two ends of the box 1 are respectively provided with an air inlet 6 and an exhaust The tuyere 7; the bottom of the box body 1 is axially provided with several ash hopper openings 3, and a dust collection bag 2 is installed on the ash hopper opening 3, and the dust collection bag 2 is a dust collection cloth bag or a PVC dust collection bag, and the dust A number of filter holes are opened on the collection bag 2, and the filter holes of the dust collection bags 2 distributed sequentially along the airflow direction are successively reduced in diameter, and are respectively used to filter dust of different particle sizes;

At least two dust-absorbing panels 5 are installed radially in the box body 1, and the vacuum-absorbing panels 5 are inserted into slots on the outer wall of the box body 1 in the form of inserts for easy cleaning or replacement;

The inner wall of the box body 1 is provided with a sound-absorbing layer 4, and the sound-absorbing layer 4 may be a mineral wool sound-absorbing board, or may be directly coated with sound-absorbing material on the inner wall.

A detector is also arranged on the inner wall of each ash hopper mouth, which is used to detect the dust accumulation height and send a signal according to the dust accumulation height, and the detector is electrically connected to the alarm device.

The working process of a noise-reducing and dust-removing device of the utility model is as follows: the dust-laden airflow enters the box body 1 directly from the air inlet 6, and since the outer diameter of the box body 1 is larger than the outer diameter of the exhaust device, the airflow velocity decreases, and the airflow and the inner wall of the box body 1 At the same time, the sound-absorbing layer 4 is attached to the inner wall of the box body 1, thereby reducing noise; when the airflow enters the box body 1, the speed slows down, and the dust mixed in the airflow will fall on the bottom of the box body 1 due to gravity At the bottom, at the same time, the ash hopper mouth at the bottom can divert the flow, and the wind body diverted to the bottom has a traction effect on the dust. The heavy dust enters the dust collection bag 2 at the bottom along with the gas, and the dust collection bag 2 filters the airflow, collects dust and lowers the dust. The effect of airflow noise; the dust suction plate 5 is installed at the tail of the box body 1, and the dust suction plate 5 can be drawn out relative to the box body 1, which is convenient for jacking up for cleaning, and a plurality of dust suction plates at the tail are set to prevent the tail from escaping. The outflow of air mixed with dust is discharged into the atmosphere.

When the dust-laden gas enters the box body 1 from the air inlet 6, due to the widening of the air passage, the airflow velocity naturally decreases, and the dust entrained in the gas naturally falls to the bottom due to the action of gravity, and the ash hopper opening 3 at the bottom has the function of shunting, Part of the air flow will be discharged from the dust hopper opening 3, and the air flow will be drawn at the same time. The dust will be filtered after entering the dust collection bag 2 and collected in the dust collection bag 2. The heavy dust will be preferentially collected in the dust collection bag 2 near the air inlet 6. In the process, the light dust is collected in the dust collection bag 2 near the tail air outlet 7, and part of the dust remaining in the dusty gas is absorbed by the dust suction plate 5. The air exhaust noise is greatly reduced by widening the air duct to reduce the wind speed, diverting the flow of each ash hopper mouth 3, and the noise reduction effect of the sound-absorbing layer and the dust collection bag 2.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the art can think of it without creative work within the technical scope disclosed in the utility model. All changes or replacements should fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
