Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection device for biomass fuel processing. Background Technology

[0002] Biomass fuel refers to a new type of clean fuel that can be directly burned by burning biomass materials, which are generally agricultural and forestry wastes (such as straw, sawdust, bagasse, rice husks, etc.). These materials are processed through crushing, mixing, extrusion, drying and other processes.

[0003] However, processing agricultural and forestry waste generates a lot of dust, which affects normal processing and seriously affects the health of operators. Therefore, it is necessary to use dust collection devices to collect dust. Most current dust collection methods require spraying to reduce dust, which is not convenient for subsequent dust recycling and processing, and is relatively inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in collecting dust and the complexity of recycling and processing it, and to propose a dust collection device for biomass fuel processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust collection device for biomass fuel processing includes a dust collection box, with an air inlet and an air outlet on both sides of the dust collection box. A dust collection box is provided at the bottom of the dust collection box, and a partition is provided above the dust collection box to divide the inner cavity of the dust collection box into an air inlet chamber near the air inlet and a dust filter chamber on the other side.

[0007] The partition is provided with multiple ventilation holes evenly distributed at the bottom, the dust filter chamber is provided with multiple filter plates evenly distributed, and the air outlet is equipped with a fan.

[0008] Multiple inclined, slow-fall separation plates are evenly installed above the dust collection box.

[0009] Preferably, all of the filter plates are inclined and positioned between the air vent and the air outlet.

[0010] More preferably, the filter plate is slidably installed in the dust collection box, and a sealing plate is provided on one side of the filter plate corresponding to the side wall of the dust collection box. The dust collection box is provided with a plurality of mounting slots for installing the filter plate.

[0011] Preferably, the dust collection box is slidably inserted into the dust removal box, and a sealing plate is provided on one side of the dust collection box corresponding to the dust removal box.

[0012] Preferably, the air inlet chamber is provided with multiple baffles.

[0013] More preferably, the plurality of the deflectors gradually increase in height toward the side away from the air inlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, multiple inserted filter plates ensure the dust filtration effect while facilitating the maintenance and replacement of the filter plates, thus ensuring the ease of use of the dust collection device.

[0016] 2. In this utility model, the design of the guide plate and the slow-fall isolation plate avoids the incoming airflow from being directly blown into the dust collection box, causing the dust to be stirred up again, thus ensuring the stable operation of the dust collection box.

[0017] 3. In this utility model, dust is collected by filtering dust through a filter plate, which avoids the complicated problem of subsequent dust recovery in the spraying method and facilitates the handling of dust.

[0018] This utility model features a novel design and simple structure. It filters and separates dust through multiple filter plates, ensuring effective dust collection. At the same time, the dust can be easily recycled, ensuring the ease of use of the dust collection device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4A dust collection device for biomass fuel processing includes a dust collection box 1. The dust collection box 1 has an air inlet 11 and an air outlet 12 on both sides. The bottom of the dust collection box 1 is provided with a dust collection box 4. A partition 3 is provided above the dust collection box 4, which divides the inner cavity of the dust collection box 1 into an air inlet chamber near the air inlet 11 and a dust filter chamber on the other side. The airflow is guided by the partition 3 and filtered through the dust filter chamber. The filtered dust falls into the dust collection box 4 for collection, which facilitates subsequent recycling and processing.

[0026] The partition 3 has multiple ventilation holes 31 evenly distributed at its lower part, and the dust filter chamber is evenly arranged with multiple filter plates 5. A fan 2 is installed in the air outlet 12. The fan 2 keeps the inner cavity of the dust collector 1 under negative pressure. The dust to be absorbed and the airflow are sent into the dust filter chamber through the air inlet 11 and the airflow is sent through the ventilation holes 31. The air is filtered by the multiple filter plates 5, and the purified air is sent out through the air outlet 12.

[0027] Multiple inclined, slow-descent separation plates 32 are evenly arranged above the dust collection box 4. The design of the slow-descent separation plates 32 prevents airflow from directly blowing into the dust collection box 4 and stirring up the stored dust again, increases the working pressure of the filter plate 5, and ensures the dust filtration and collection effect.

[0028] Based on the above technical solution, when dust removal is required during the biomass fuel production process, the blower 2 is started to put the dust collection box 1 under negative pressure, and dust is sucked through the air inlet 11. The location to be dusted is connected to the air inlet 11 through a pipe, or the air inlet 11 can be used directly for dust suction. The dust-laden airflow entering the dust collection box 1 is blocked by the partition 3, and larger particles are separated from the airflow and fall into the dust collection box 4 through the slow-fall separation plate 32. The airflow enters the dust filter chamber through the ventilation hole 31 and filters the dust through multiple filter plates 5. After filtration, the dust is sent out through the air outlet 12.

[0029] In this technical solution, such as Figure 1-4 As shown, the multiple filter plates 5 are all inclined and positioned between the air vent 31 and the air outlet 12. The inclined arrangement increases the contact area between the filter plate 5 and the airflow, improves the filtration efficiency, and prevents dust from clogging the filter plate 5 and affecting its working effect.

[0030] In this technical solution, such as Figure 1-4 As shown, the filter plate 5 is slidably installed in the dust collector 1, and a sealing plate 51 is provided on one side of the filter plate 5 corresponding to the side wall of the dust collector 1. The dust collector 1 is provided with multiple mounting slots 52 for installing the filter plate 5. The insertion and installation design of the filter plate 5 facilitates the replacement of the filter plate 5, and the sealing plate 51 ensures the sealing effect of the filter plate 5 installation, avoiding affecting the negative pressure state in the dust collector 1 and ensuring good dust collection effect of the air inlet 11.

[0031] In this technical solution, such as Figure 1-4 As shown, the dust collection box 4 is slidably inserted into the dust collection box 1, and a sealing plate 41 is provided on one side of the dust collection box 4 corresponding to the dust collection box 1. This facilitates the removal of the dust collection box 4 for dust collection, and at the same time, the sealing plate 41 ensures a negative pressure state in the dust collection box 1.

[0032] In this technical solution, such as Figure 1-4 As shown, multiple guide plates 6 are arranged in the air inlet chamber, and the multiple guide plates 6 gradually increase in height towards the side away from the air inlet 11. The guide plates 6 guide the incoming dust-laden airflow, preventing the dust-laden airflow from being blown into the dust collection box 4 at high speed, and also causing larger particles to lose kinetic energy and fall, ensuring the separation effect between dust and airflow.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
