Description

A dust removal box with convenient replacement of dust discharge port

Technical Field

The utility model relates to the technical field of dust collectors, in particular to a dust removal box which is convenient for replacing a dust discharge port.

Background Art

Bag filter is a common air purification equipment, mainly used to filter dust, smoke and other air pollutants generated in industrial production or large buildings, so as to improve indoor air quality and protect people's health. Its working principle is to generate strong airflow through high-pressure fan, suck polluted air into the dust collector, enter the filter bag chamber after pretreatment, and then intercept dust and other solid particles in the dust-containing gas on the bag through the filtering action of a series of filter bags. A vibration device is set above the bag, and an ash hopper is set below the bag. Through vibration, solid particles such as dust are shaken off into the ash hopper to achieve centralized recovery of dust; during use, only regular cleaning or replacement of the bag is required to maintain the dust removal effect. However, the prior art pays little attention to the disassembly and cleaning of the ash hopper. The ash hopper of most bag filters needs to be shut down after the dust is full, and then the ash hopper is removed from the bag filter, cleaned and installed again. The dust box cleaning process is extremely cumbersome and time-consuming, which greatly affects the dust removal efficiency of the bag filter.

In order to solve the above technical problems, Chinese patent CN219764838U discloses a replaceable dust box for bag dust collector, including two dust box bodies, a replacement trolley and a guide rail, two parallel linear guide rails are arranged on the ground below the dust collector body, the replacement trolley can be linearly slidably arranged on the guide rail, a driving device is arranged on the replacement trolley, and the two dust box bodies are fixedly placed on the replacement trolley in parallel along the sliding direction of the replacement trolley. Under the action of the driving device, the replacement trolley drives the two dust box bodies to switch the combined or disengaged state at the ash hopper outlet at the bottom of the dust collector body. The above patent can not affect the normal operation of the dust collector during the dust box replacement process, but there is a time difference for the complete disassembly and replacement of the ash hopper, and some dust will still escape, affecting the dust removal effect.

Therefore, it is necessary for technical personnel in this field to provide a dust removal box with an easy-to-replace ash discharge port, so that operators can replace the ash discharge port at any time, while reducing dust escape and improving the stability and efficiency of use.

DETAILED DESCRIPTION

Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

Please refer to Figure 1. The utility model provides a dust collector box with an easily replaceable dust discharge port, which is used to be installed on a dust collector box body 10. The dust collector box body 10 is a square shell-shaped structure with a hollow interior. An air inlet 11 is provided on one side of the dust collector box body 10, and an exhaust port 12 is provided on the other side of the dust collector box body 10. A filter bag 13 is provided in the dust collector box body 10. The replaceable dust discharge port is arranged at the bottom of the dust collector box body 10 and directly faces the filter bag 13. When in use, a high-pressure fan (not shown) generates a strong airflow to suck polluted air into the dust collector, and after pre-treatment, the polluted air passes through the filter bag 13. The dust and other solid particles in the dust-containing gas are trapped on the filter bag 13 by the filtering effect of the filter bag 13. A vibration device (not shown) is arranged above the filter bag 13, and the replaceable dust discharge port is arranged below the cloth bag. The dust and other solid particles are shaken off into the replaceable dust discharge port by vibration, so as to realize the centralized recovery of dust.

Further, the replaceable ash discharge port includes a plurality of ash discharge hopper bodies 20, which are evenly arranged at the bottom of the dust box body 10, and are detachably connected to the bottom of the dust box body 10 by fasteners such as bolts or screws, and the ash discharge hopper body 20 faces the filter bag 13. The ash discharge hopper body 20 is a conical shell structure, and the inner wall of the ash discharge hopper body 20 is an inclined surface. A valve 21 is provided at the bottom of the ash discharge hopper body 20. When in use, the valve 21 is used to ensure the ash discharge of the ash discharge hopper body 20. Dust falling from the dust box body 10 will gather in the ash discharge hopper body 20. When the valve 21 is opened, the dust is discharged from the ash discharge hopper body 20. When the valve 21 is closed, the dust gathers in the ash discharge hopper body 20. Preferably, the valve 21 is a butterfly valve.

Specifically, there are four ash discharge hopper bodies 20, and the four ash discharge hopper bodies 20 are evenly arranged longitudinally from the air inlet 11. That is, one ash discharge hopper body 20 is close to the air inlet 11, and the others are arranged longitudinally in sequence.

During use, since the ash hopper main body 20 close to the air inlet 11 receives much more dust than the ash hopper main body 20 far from the air inlet 11, the utility model provides a plurality of ash hopper main bodies 20 and evenly arranges the plurality of ash hopper main bodies 20 between the air inlet 11 and the air outlet 12, so that the dust falling from the dust removal box main body 10 will fall into the plurality of ash hopper main bodies 20 in sequence from more to less, thereby making the ash hopper main body 20 close to the air inlet 11 require replacement, cleaning and maintenance more frequently, while the cleaning frequency of the remaining ash hopper main bodies 20 is greatly reduced, thereby improving the service life and stability of use. At the same time, compared with one ash hopper, the plurality of ash hopper main bodies 20 adopted in the utility model are smaller in size, greatly reducing the labor intensity, and are more conducive to replacement and maintenance.

Furthermore, the dust removal box body 10 is provided with a slide groove 14, and a slide plate 15 is slidably provided in the slide groove 14, and the slide plate 15 is directly opposite to an ash discharge hopper body 20; preferably, the width of the slide plate 15 is consistent with the width of the upper opening of the ash discharge hopper body 20. The slide plate 15 is located below the filter bag 13 to prevent dust in the filter bag 13 from falling.

When in use, the slide plate 15 is inserted into the slide groove 14 and slid above an ash hopper body 20 to block dust from falling in, making it convenient for operators to replace the ash hopper body 20, thereby achieving non-stop replacement and improving processing efficiency.

It can be understood that a sealing cloth (not shown) is installed on the slide groove 14 to prevent internal dust from escaping from the dust removal box body 10 and ensure the sliding stability of the slide plate 15.

The specific operation method of the utility model is as follows: during dust removal: a strong airflow is generated by the high-pressure fan to suck the polluted air into the dust collector, and after pre-treatment, it passes through the filter bag 13, a vibration device is arranged above the filter bag 13, and a plurality of ash discharge hopper bodies 20 are arranged below the bag, and solid particles such as dust are shaken off into the ash discharge hopper body 20 through vibration, thereby realizing centralized recovery of dust.

When discharging dust: insert the slide plate 15 into the slide groove 14 and slide it above an ash discharge bucket body 20 to block dust from falling in, remove an ash discharge bucket body 20 facing the slide plate 15, replace it with a new ash discharge bucket body 20, and complete the replacement.

The utility model sets a plurality of ash hopper bodies 20 and evenly arranges the plurality of ash hopper bodies 20 between the air inlet 11 and the air outlet 12, so that the dust falling from the dust box body 10 will fall into the plurality of ash hopper bodies 20 in order from large to small, so that the ash hopper bodies 20 near the air inlet 11 need to be replaced, cleaned and repaired more frequently, while the cleaning frequency of the remaining ash hopper bodies 20 is greatly reduced, thereby improving the service life and stability of use. At the same time, compared with one ash hopper, the plurality of ash hopper bodies 20 used in the utility model are smaller in size, greatly reducing the labor intensity and being more conducive to replacement and maintenance.
