Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for air separators, in particular to a dust removal device for air separators. Background Art

[0002] A grain air separator is an agricultural machine used to remove impurities and undesirable grains from grain. It utilizes the principles of air flow to adjust the speed and direction of the airflow to separate light impurities (such as dust and leaf fragments) from heavy impurities (such as stones and clods of earth), as well as unfilled or immature grains, thereby improving the purity and quality of the grain.

[0003] Some agricultural air separators are often small in size and suitable for use by individual farmers. They can effectively meet farmers' daily needs. However, due to the low requirements of the working environment and size limitations, such separators often only perform air separation without collecting and removing impurities generated during the air separation process. This results in a relatively harsh working environment, and impurities and dust are easily blown around, affecting the health of operators and the cleanliness of the surrounding environment.

[0004] As the living standards of farmers improve, higher requirements are placed on the working environment. Therefore, there is an urgent need on the market for a device that can collect and remove impurities and dust from air separators. Utility Model Content

[0009] The inner sides of the sealing rings are all fixedly connected with a plurality of sealing strips; this ensures the sealing performance during the dust removal process.

[0010] A bracket is fixedly connected to the middle of the conical opening, and a fan is fixedly connected to the middle of one side of the bracket; this enhances the air flow suction capacity and improves the dust removal efficiency.

[0011] A notch is provided in the middle of the dust removal pipe, a filter plate is inserted into the middle of the notch, and a plurality of filter openings are provided in the middle of the filter plate; this captures impurities and intercepts some of the blown grains.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the drawings of the embodiments of the present utility model Figure 1-6 , and clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0028] As Figure 1-6 shown: This embodiment provides a pneumatic separation machine dust removal device, which includes a dust removal pipe 100 for connecting a pneumatic separation machine. One end of the dust removal pipe 100 far from the pneumatic separation machine is fixedly connected with a discharge hood 101. The bottom of the discharge hood 101 is fixedly connected with an annular plate 102. The annular plate 102 is made of metal. An annular groove 103 is opened at the bottom of the annular plate 102. Both ends of the bottom of the annular plate 102 are provided with pressing plates 104 through hinges. The pressing plates 104 are all arc-shaped. Arc-shaped magnets 105 are fixedly connected to the bottoms of the pressing plates 104. Pull rods are fixedly connected to the sides of the pressing plates 104 far from the arc-shaped magnets 105. When the pressing plates 104 rotate, the arc-shaped magnets 105 will be driven to insert into the annular groove 103. The width of the arc-shaped magnet 105 is equal to the width of the notch of the annular groove 103. When the two arc-shaped magnets 105 are located in the annular groove 103, they can fix the storage bag;

[0029] When the air classifier starts to work, dust enters the dust removal pipe 100 along with the air flow and is finally guided to the discharge hood 101. The operator can rotate the pressing plate 104 through the pull rod. During the rotation process, the arc-shaped magnet 105 will be driven and inserted into the annular groove 103. Eventually, the arc-shaped magnet 105 is evenly docked with the annular groove 103. When the two arc-shaped magnets 105 are located in the annular groove 103, they can fix the storage bag. In this way, the dust can be transferred from the discharge hood 101 to the storage bag without leakage or pollution. Through this design, the dust removal device of the air classifier can not only effectively collect and store dust, but also ensure the cleanliness and safety of the environment during the working process. At the same time, the rotatable pressing plate 104 and arc-shaped magnet 105 increase the flexibility of the equipment and facilitate the quick replacement of the storage bag.

[0030] The connecting block 201 is as Figure 1 、 2 、shown in Figure 3.

[0031] One end of the dust removal pipe 100 close to the air classifier is fixedly connected with a connecting block 201. A tapered opening 202 is provided in the middle of the connecting block 201. The opening of the tapered opening 202 close to the dust removal pipe 100 is smaller than the end far from the dust removal pipe 100. One end of the connecting block 201 is fixedly connected with a plurality of sealing rings 203 arranged with the center of the connecting block 201 as the axis. The axes of the sealing rings 203 coincide. The diameter of the sealing rings 203 gradually increases from the center of the connecting block 201 to the edge of the connecting block 201. One side of each sealing ring 203 is fixedly connected with a plurality of arc-shaped plates 204 arranged in an annular array. The arc-shaped plates 204 are made of steel plates and have a certain elasticity. The diameter of the arc-shaped plates 204 close to the sealing ring 203 is larger than the end far from the sealing ring 203. The diameter of the arc-shaped plates 204 close to the sealing ring 203 is the same as that of the adjacent sealing ring 203. A plurality of sealing strips 205 arranged in an array are fixedly connected to the inner side of the sealing ring 203;

[0032] Before the air classifier works, insert a group of arc-shaped plates 204 with the diameter closest to the diameter of the air outlet of the air classifier to be docked into the interior of the air classifier. Since the diameter of the arc-shaped plates 204 far from the connecting block 201 is smaller, it is beneficial for the arc-shaped plates 204 to be inserted into the air classifier. When the arc-shaped plates 204 continuously enter the air outlet, the larger-diameter rear side of the arc-shaped plates 204 will gradually fit tightly against the inner wall of the air outlet of the air classifier until one end of the air outlet is inserted between two adjacent sealing rings 203, and the outer wall of the air outlet fits against the sealing strip 205 to achieve sealing. At the same time, the inner wall of the adjacent group of arc-shaped plates 204 with a larger diameter will fit against the outer wall of the air outlet. When docking with the air outlets of air classifiers with different diameters, different diameters of arc-shaped plates 204 can be flexibly selected, so that this device can be used with air classifiers of more diameter sizes;

[0033] When the air separator starts working, the dust impurities screened out in the air separator enter the connecting block 201 through the air outlet. When passing through the tapered mouth 202, due to the inconsistent diameters at both ends of the tapered mouth 202, the dust impurities are accelerated when passing through the tapered mouth 202 because the opening of the tapered mouth 202 close to the dust collection pipe 100 is smaller and the opening of the end away from the dust collection pipe 100 is larger. Therefore, the airflow is accelerated when passing through the tapered mouth 202. This accelerated airflow can more effectively suck the dust impurities into the dust collection pipe 100. Then, the dust impurities will enter the dust collection pipe 100 and be quickly guided to the exhaust hood 101 along the dust collection pipe 100.

[0034] Fan 207 Figure 3 、 4 As shown,

[0035] A bracket 206 is fixedly connected to the middle of the conical opening 202, and a fan 207 is fixedly connected to the middle of one side of the bracket 206;

[0036] When the air separator is working, the operator controls the fan 207 to start running, generating airflow. Combined with the design of the tapered mouth 202, the airflow will be accelerated, thereby more effectively sucking dust impurities into the dust removal pipe 100. Then, the dust impurities will be quickly guided along the dust removal pipe 100 to the exhaust hood 101.

[0037] Filter plate 301 Figure 4 As shown,

[0038] A notch is provided in the middle of the dust removal pipe 100, a filter plate 301 is inserted in the middle of the notch, a plurality of filter ports arranged in an array are provided in the middle of the filter plate 301, and a pull rod is fixedly connected to the top of the filter plate 301;

[0039] When dust impurities are accelerated into the dust removal pipe 100, they first come into contact with the filter plate 301. The filter port on the filter plate 301 allows airflow to pass through, but at the same time captures and filters out dust impurities. As the air separator continues to work, more and more dust impurities will accumulate on the filter plate 301. The operator can use the pull rod to pull the filter plate 301 out of the slot for cleaning or replacement to ensure that the dust removal device continues to operate efficiently.

[0040] Pad 302 such as Figure 4 、 5 As shown,

[0041] The dust removal pipe 100 is located between the filter plate 301 and the connecting block 201. The bottom inner wall of the pipe body is fixedly connected with a pad 302. A material port is opened at the bottom of the pipe body of the dust removal pipe 100 between the pad 302 and the filter plate 301. A support plate 303 is hinged to one side of the material port through a hinge. The bottom of the support plate 303 and the bottom of the dust removal pipe 100 are both fixedly connected to a limit plate. The middle of the limit plate is plugged with the same fixing column.

[0042] During filtration, a material trough is formed between the cushion block 302 and the filter plate 301. When dust impurities pass through the filter plate 301, larger impurities or grains blown out by the air separator will be intercepted in the trough. As the impurities on the filter plate 301 accumulate, the dust impurities in the cavity will gradually increase. When the dust impurities in the trough accumulate to a certain extent, the operator can open the support plate 303, make the support plate 303 rotate around the hinge, pour out the dust impurities in the cavity for cleaning. The design of the limit plate and the fixed column ensures the stability of the support plate 303 when it is opened and closed, preventing unnecessary movement or shaking of the support plate 303, and can screen the materials blown out by the air separator again during the dust collection process, improving the recovery rate of grains.

[0043] Working principle:

[0044] When the air separator is working, it is connected to the air separator through the connecting block 201. The generated dust enters the dust removal pipe 100 along with the air flow. The connecting block 201 is designed with a conical opening 202 to accelerate the air flow and more effectively suck in dust impurities. The filter plate 301 allows the air flow to pass through while capturing and filtering out dust impurities. The filter plate 301 can be periodically pulled out through the pull rod for cleaning or replacement to ensure continuous and efficient operation. A material trough is formed between the filter plate 301 and the cushion block 302, and larger impurities or grains are intercepted in the trough. When the dust impurities in the trough accumulate to a certain extent, the operator can open the support plate 303 and rotate it around the hinge to pour out the dust impurities for cleaning. The dust is finally guided to the discharge hood 101. The bottom of the discharge hood 101 uses an arc-shaped magnet 105 to fix the storage bag, ensuring that the dust is transferred from the discharge hood 101 to the storage bag to avoid leakage or pollution. The air flow generated by the operation of the fan 207 cooperates with the design of the conical opening 202 to accelerate the air flow and suck in dust impurities.

[0045] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0046] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
