The utility model has the advantages that: after the cotton dust enters the dust discharge chamber from the intake pipe, under the filtering effect of the mesh of the inner shell, a part of the cotton dust is left in the dust discharge chamber and falls into the flap valve at the bottom, so as to realize the collection of cotton dust.

Description

Cotton dust collection device

technical field

The utility model relates to the technical field of refined cotton production equipment, in particular to the technical field of cotton dust treatment for refined cotton production.

Background technique

The refined cotton production process will produce cotton dust, which mainly comes from the fine cotton fibers of the refined cotton during the opening process of the raw cotton linters and the refined cotton drying process. At present, the method of collecting cotton dust is mostly to use induced draft fan to introduce the air containing cotton dust into the sealed space with filter screen, and use the filter screen to filter the cotton dust to achieve the purpose of cotton dust collection. However, in large-scale production, the filter screen needs to be cleaned frequently, otherwise it is more likely to be clogged and affect the collection of cotton dust. At the same time, manual cleaning will cause cotton dust to overflow and affect the environment.

Utility model content

In order to solve the above technical problems, the utility model provides a cotton dust collection device with good collection and treatment effect and no clogging phenomenon.

The technical solution provided by the utility model in order to solve the above-mentioned technical problems is as follows:

The cotton dust collection device includes a shell, an inner tank, an air intake pipe, an exhaust pipe, a spray pipe, a water pump, a pool, and a drain pipe. The shell is a sandwich shape composed of an inner shell and an outer shell. The upper end of the drain pipe is connected with the exhaust pipe, the lower end of the drain pipe is located in the pool, the water inlet of the water pump is connected with the pool, and the water outlet of the water pump is connected with the spray pipe inside the exhaust pipe.

Preferably, a spiral material guide plate is fixedly installed on the inner wall of the outer casing.

Preferably, a valve plate is hinged and elastically mounted on the water retaining plate.

Preferably, a baffle plate corresponding to the valve plate is installed on the inner top of the exhaust pipe.

The beneficial effect that the utility model can reach by adopting above-mentioned technical solution is:

1. By arranging the side wall of the shell into a sandwich shape, a dust discharge cavity is formed between the inner shell and the outer shell, which is beneficial for cotton dust to enter the dust discharge cavity from the intake pipe, and under the filtering effect of the mesh of the inner shell, a part of the cotton dust is left in the dust discharge cavity and falls into the flap valve at the bottom to realize the collection of cotton dust;

2. By installing a spiral material guide plate on the inner wall of the outer shell, it is beneficial for the cotton dust to be smoothly concentrated and slide down into the flap valve under the action of the material guide plate to achieve a better cotton dust collection effect, and it can also prevent the cotton dust from adhering to the mesh of the inner shell and blocking the mesh;

3. By setting the liner inside the shell, the liner can collect the cotton dust entering from the upper hole of the inner shell again, and improve the collection effect of cotton dust;

4. By installing a spray pipe in the exhaust pipe, the final exhausted air can be washed and collected to ensure the cleanliness of the final exhausted air, meet the gas emission standard, and provide a good working environment for workers;

5. By setting an elastic windshield in the exhaust pipe, the exhaust volume can be limited by the elastic windshield, and the flow speed of cotton dust in the casing can be appropriately reduced, which is beneficial for the cotton dust to stay in the casing to the greatest extent, so as to realize the effective collection of cotton dust.

Implementation

As shown in Figure 1, the cotton dust collection device includes a housing 1, an inner tank 2, an air intake pipe 3, an exhaust pipe 4, a spray pipe 5, a water pump 6, a pool 7 and a drain pipe 8. The housing is a sandwich formed by an inner housing 9 and an outer housing 10, and a dust discharge chamber 11 is formed between the inner housing 9 and the outer housing 10. The inner housing 9 is provided with a mesh 12 communicating with the ash discharge chamber 11. 11 is connected, when in use, by installing an induced draft fan on the intake pipe 3, the air containing cotton dust is introduced into the housing 1 by the effect of the induced draft fan. The top of the housing 1 is provided with an exhaust port 13, and the liner 2 is installed at the exhaust port 13 inside the housing 1. One end of the exhaust pipe 4 is connected with the exhaust port 13 on the top of the housing 1. The spray pipe 5 is fixedly installed on the inner top of the exhaust pipe 4. The upper end of drainpipe 8 is connected with exhaust pipe 4, and the lower end of drainpipe 8 is positioned in pool 7, realizes the reuse of spraying water, and the water inlet of described water pump 6 is communicated with pool, and the water outlet of water pump 6 is connected with spray pipe 5 inside exhaust pipe 4, and the inner bottom of described exhaust pipe 4 is positioned at the left side of spray pipe 5 and is installed with water retaining plate 15, prevents the spray water in exhaust pipe 4 from flowing back into housing 1, and the bottom of described housing 1 is equipped with flap valve 17, the inside of housing 1 and The dust discharge chamber 11 communicates with the flap valve 17 respectively, and a spiral material guide plate 14 is fixedly installed on the inner wall of the outer casing 10, which is beneficial to the cotton dust under the action of the material guide plate 14, smoothly concentrates and slides down into the flap valve 17 to achieve a better cotton dust collection effect.
