Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a grain dryer dust removal device and a grain dryer. Background Art

[0002] A grain dryer is a food dryer, which is a combination of machinery used in large-scale agriculture and industry to quickly dry and store grain. During the drying process of grain, a large amount of dust will adhere to the surface of the grain. If the dust is not removed in time, the processing effect of the grain will be affected.

[0003] At present, there are two dust removal methods for grain dryers on the market. One is to use the exhaust fan of the dryer to remove dust, but the pipe of this structure is too long. When the grain is relatively moist, especially in the early stage of drying, it will cause blockage. The other dust removal method is to equip it with a special dust removal fan for dust removal. However, in actual applications, due to the presence of a certain negative pressure in the machine body, the dust removal effect of this method is not ideal.

[0004] In the prior art, a Chinese patent with a publication number of CN205245762U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A new type of dust removal device for a grain dryer, including a dryer housing and an upper box body installed on the upper part of the elevator, and a flow tube that can accommodate grain passing is arranged between one side of the upper box body and the dryer housing. The utility model adopts the above-mentioned technical solution, and the grain flows through the upper side of the grain guide plate, and the cold air outside the machine body enters the flow tube from the square hole, and then is discharged from the machine body through the outlet of the exhaust fan, forming a reverse airflow, which not only drives the dust in the grain to be lifted, but also effectively alleviates the negative pressure effect in the machine body, and has a good dust removal effect, so that there is basically no dust in the grain discharged from the machine body, and the dust concentration in the air is less than 6mg / m3, which is more conducive to environmental protection. However, there will be a problem that the dust removal work is only carried out at the feed port, and the dust removal time is short, which is easy to cause the dust removal effect to be unsatisfactory, and has certain limitations. Summary of the invention

[0005] The utility model aims to provide a grain dryer dust removal device and a grain dryer to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A grain dryer dust removal device and a grain dryer, comprising a base; a dryer body is fixedly installed on the top of the base, one end of the dryer body is fixedly connected to a controller, a dust collecting box is fixedly installed on the top of the base on one side of the dryer body, a feed frame is fixedly installed on one side of the dryer body on the top of the dust collecting box, a dust suction component is provided at the bottom of the feed frame, and the dust suction component is used to remove dust from materials inside the feed frame, a discharge frame is fixedly installed at the bottom of the dryer body, a baffle is slidably connected to the inside of the discharge frame, a dust collecting component is provided at the bottom of the discharge frame, and the dust collecting component is used to remove dust from materials inside the discharge frame, a filter plate is fixedly installed inside the dust collecting box, a box door is rotatably installed at one end of the dust collecting box, one side of the dust collecting box is fixedly connected to a box body, and a fan is fixedly installed inside the box body.

[0008] By installing a controller, the fan can be controlled, which makes it convenient for users to use the device. By installing a filter plate, the dust inside the dust box can be intercepted and filtered, so that the dust can be stored inside the dust box, which is convenient for users to clean the dust later. When the user pours the material into the feed frame, the fan can be used to absorb the dust contained in the material into the dust box through the dust suction component. By installing a baffle, the opening of the discharge frame can be blocked to prevent the material from being discharged through the discharge frame during the drying process, which affects the drying effect of the material. When the material is dried inside the dryer body, the baffle can be pulled to the other side to allow the material to be discharged through the discharge frame. At the same time, the fan can be used to absorb the remaining dust contained in the material into the dust box through the dust collecting component, thereby achieving double dust removal and improving the dust removal effect of the material.

[0009] A further improvement of the technical solution of the utility model is that the dust suction component includes a dust suction pipe, both ends of which are fixedly connected to the bottom of the feed frame and the top of the dust collecting box respectively, a first filter is fixedly installed on the bottom of the feed frame, and the first filter is just located on the top of the dust suction pipe, a rotating frame is rotatably installed inside the feed frame, and a plurality of connecting plates are fixedly connected to the periphery of the rotating frame.

[0010] The above technical solution is adopted. In this solution, the material and dust inside the feed frame can be filtered by installing the first filter, ensuring that the dust can move downward to the inside of the dust suction pipe through the first filter, and the material will normally enter the inside of the dryer body. By installing the rotating frame and the connecting plate, when the material comes into contact with the connecting plate, the connecting plate can be squeezed, and the rotating frame can be used to drive the connecting plate to rotate, and the material can be turned over, thereby ensuring that more dust can be adsorbed into the inside of the dust suction pipe, thereby improving the dust removal effect.

[0011] A further improvement of the technical solution of the utility model is that a plurality of through holes larger than the volume of each material are provided on the surface of the connecting plate.

[0012] By adopting the above technical solution, in this solution, by opening a plurality of through holes larger than the volume of each material on the surface of the connecting plate, some materials can directly pass through the through holes of the connecting plate and enter the interior of the dryer body, thereby avoiding material blockage.

[0013] A further improvement of the technical solution of the utility model is that the dust collecting component includes a dust collecting pipe, both ends of which are fixedly connected to the bottom of the discharge frame and the other side of the dust box respectively, and a second filter is installed inside the discharge frame at the bottom of the baffle through a spring, and the second filter passes through one side of the discharge frame and extends out a part.

[0014] The above-mentioned technical solution is adopted. In this solution, the material and dust inside the discharge frame can be filtered by installing a second filter, ensuring that the dust can move downward to the inside of the dust collecting pipe through the second filter, and the material can be discharged normally from the other side of the second filter. By installing a spring, when the material comes into contact with the second filter, the second filter can be squeezed. At the same time, the elastic force of the spring itself can drive the second filter to shake up and down, and the material is turned over, thereby ensuring that more dust can be adsorbed into the inside of the dust collecting pipe, further improving the dust removal effect.

[0015] A further improvement of the technical solution of the utility model is that a plurality of sliding blocks are fixedly installed at both ends of the second filter screen, and the sliding blocks are slidably connected to the inner wall of the discharge frame.

[0016] The above technical solution is adopted. In this solution, the trajectory of the second filter screen driven by the spring to shake can be guided and limited by installing a slider, thereby ensuring that the second filter screen moves in a straight line.

[0017] A further improvement of the technical solution of the utility model is that a material guide plate is fixedly installed inside the dust collecting box on the other side of the filter plate, and the top of the material guide plate is an inclined surface inclined toward the bottom of one end.

[0018] The above-mentioned technical solution is adopted. In this solution, by setting the top of the guide plate to an inclined surface inclined toward the bottom of one end, when the user opens the box door, the guide plate can automatically drive the dust to slide to one end, so that the user does not need to manually move the dust out, thereby reducing the user's workload and facilitating the user to clean the dust.

[0019] A further improvement of the technical solution of the utility model is that a pull block is fixedly installed on the other side of the baffle.

[0020] The above technical solution is adopted. In this solution, the contact area between the user's hand and the baffle can be enlarged by installing the pull block, thereby facilitating pulling the baffle and moving and adjusting the baffle.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a grain dryer dust removal device and a grain dryer. Through the mutual cooperation between the dust suction component and the dust collection component, dust suction processing is respectively performed on the feed frame and the discharge frame, and the grain and dust can be completely separated, thereby improving the dust removal effect.

[0023] 2. The utility model provides a grain dryer dust removal device and a grain dryer. By installing a rotating frame and a connecting plate, when the material comes into contact with the connecting plate, the rotating frame can be used to drive the connecting plate to rotate, and the material can be turned over, thereby ensuring that more dust can be absorbed into the interior of the dust suction pipe, thereby improving the dust removal effect.

[0024] 3. The utility model provides a grain dryer dust removal device and a grain dryer. By installing a spring, when the material comes into contact with the second filter screen, the spring can drive the second filter screen to shake up and down to turn the material over, thereby ensuring that more dust can be adsorbed into the interior of the dust collecting pipe, further improving the dust removal effect.

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a grain dryer dust removal device and a grain dryer, including a base 1; a dryer body 2 is fixedly installed on the top of the base 1, one end of the dryer body 2 is fixedly connected to a controller 4, a dust collecting box 3 is fixedly installed on the top of the base 1 on one side of the dryer body 2, a feed frame 201 is fixedly installed on one side of the dryer body 2 on the top of the dust collecting box 3, and a dust collecting component 5 is provided at the bottom of the feed frame 201, and the dust collecting component 5 is used to remove dust from the material inside the feed frame 201.

At the same time, the fan 8 can be used to absorb the remaining dust contained in the material to the inside of the dust collecting box 3 through the dust collecting component 6, thereby realizing two dust removal operations and improving the dust removal effect of the material. By installing the pull block 1001, the contact area between the user's hand and the baffle 10 can be expanded, thereby facilitating the pulling of the baffle 10 and moving and adjusting the baffle 10.

[0037] Example 2

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dust suction component 5 includes a dust suction pipe 501, and the two ends of the dust suction pipe 501 are respectively fixedly connected to the bottom of the feed frame 201 and the top of the dust collecting box 3, and a first filter screen 504 is fixedly installed at the bottom of the feed frame 201, and the first filter screen 504 is just located at the top of the dust suction pipe 501, and a rotating frame 502 is rotatably installed inside the feed frame 201, and a plurality of connecting plates 503 are fixedly connected to the periphery of the rotating frame 502, and a plurality of through holes larger than the volume of each material are opened on the surface of the connecting plate 503.

[0040] Example 3

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the dust collecting component 6 includes a dust collecting pipe 601, and the two ends of the dust collecting pipe 601 are respectively fixedly connected to the bottom of the discharge frame 202 and the other side of the dust box 3, and a second filter screen 602 is movably installed inside the discharge frame 202 at the bottom of the baffle 10 through a spring 603.

By installing the spring 603, when the material comes into contact with the second filter 602, the second filter 602 can be squeezed. At the same time, the elastic force of the spring 603 itself can drive the second filter 602 to shake up and down, and the material is turned over, thereby ensuring that more dust can be adsorbed into the inside of the dust collecting pipe 601, further improving the dust removal effect.
