Description

Technical Field

[0001] This utility model relates to the field of raw material impurity removal technology, specifically a raw material impurity removal device for biomass pellet fuel production. Background Technology

[0002] With the transformation of energy structure and the promotion of environmental protection policies, biomass pellet fuel has gradually become one of the important clean energy sources to replace traditional fossil fuels due to its advantages such as renewability, low carbon emissions and abundant resources. Its main raw materials include agricultural and forestry waste such as sawdust, straw, rice husks, peanut shells and sugarcane bagasse. These raw materials are often mixed with various impurities, such as stones, metal fragments, sand, plastics, glass and ropes, which not only affect the normal operation of subsequent processing equipment, but may also reduce the combustion performance and quality of the final product. Therefore, it is necessary to use raw material impurity removal devices for biomass pellet fuel production to remove impurities from these raw materials.

[0003] However, current raw material impurity removal devices for biomass pellet fuel production still have the following shortcomings: In the biomass pellet fuel production process, the raw material impurity removal device plays a crucial role. After the device completes the impurity removal process, the clean raw material is loaded into the raw material collection frame. However, in most cases, the separated impurities are directly scattered on the ground, which not only causes a messy production site but may also pose hygiene and safety hazards. Although some devices are equipped with impurity collection frames to collect impurities, in actual operation, as impurities accumulate, the impurities in the collection frame will pile up higher and higher. When the impurities accumulate to a certain height, they will block the holes on the impurity removal screen. If the blocked holes are not cleared in time, the filtration function of the impurity removal screen will be greatly reduced, which will seriously affect the working effect of the entire impurity removal device and reduce the production quality and efficiency of biomass pellet fuel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material impurity removal device for biomass pellet fuel production, which facilitates the removal of impurities generated during the impurity removal process from the removal area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material impurity removal device for biomass pellet fuel production, comprising an impurity removal machine body and an impurity removal screen connected to the impurity removal machine body. A rectangular mounting plate is fixedly connected to the lower front surface of the impurity removal machine body, and a rectangular mounting rod is fixedly connected to the front surface of the rectangular mounting plate. A track groove is provided on the rectangular mounting rod, and a raw material holding frame is fixedly connected in the track groove. Multiple moving wheels are slidably connected in the impurity removal area of ​​the impurity removal screen in the track groove. The upper ends of the multiple moving wheels are fixedly connected to the same impurity holding frame. The end of the impurity holding frame away from the raw material holding frame is open, and a baffle is slidably connected in the opening.

[0006] Furthermore, a first handle is fixed to the surface of the impurity container away from the impurity removal machine body.

[0007] Furthermore, a limiting threaded hole is provided on the side surface of the rectangular mounting rod away from the impurity removal machine body. The limiting threaded hole passes through the rotating part of one of the moving wheels. A limiting threaded rod is internally threaded into the limiting threaded hole. The impurity holding frame is threadedly fastened and restricted to the impurity removal area of ​​the impurity removal screen by the limiting threaded rod.

[0008] Furthermore, a push plate is slidably connected inside the side of the impurity container frame closest to the raw material container frame. A connecting rod is fixed to the surface of the push plate away from the raw material container frame. The connecting rod passes through the baffle and extends outward. A second handle is fixed to the end of the connecting rod away from the raw material container frame. A triangular cutting strip is fixed to the lower surface of the push plate away from the raw material container frame. The lower surface of the triangular cutting strip is in close contact with the lower inner wall of the impurity container frame.

[0009] Furthermore, both the first handle and the second handle are provided with anti-slip sleeves.

[0010] Furthermore, an installation block is fixedly attached to the side surface of the impurity container near the second handle. The installation block is located on one side of the connecting rod. A limiting groove is provided on the upper surface of the installation block. A rectangular limiting rod is rotatably connected to the outer wall of the connecting rod in the area where the limiting groove is located. The rectangular limiting rod is adapted to and engaged with the limiting groove. The push plate is engaged and limited by the rectangular limiting rod and the installation block on the impurity container.

[0011] Furthermore, both the outer wall of the rectangular limiting rod and the inner wall of the limiting slot are provided with anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model utilizes the cooperation of a track groove, moving wheels, impurity collection frame, baffle, connecting rod, and push plate. When the device is running, impurities fall into the impurity collection frame. When the frame is about half full, the impurity collection frame is pulled so that it moves away from the impurity removal area along the track groove by the moving wheels. Then, the baffle is pulled, which moves the connecting rod and push plate. The push plate pushes the impurities to other collection areas, making the impurity removal area below the impurity removal screen cleaner, reducing the impact of impurity accumulation on the efficiency of the impurity removal screen, and making the impurity removal process more stable and efficient. The structure is simple, easy to operate, and highly practical.

[0014] 2. By setting triangular cutting strips, this utility model can improve the discharge effect of impurities from the container. With the unique tilt angle of the triangular cutting strips, it can cut into the pile of impurities like a sharp "blade" during the process of pushing impurities by the pusher plate, and cut the impurities out of the impurity container, thereby making the inside of the impurity container cleaner.

[0015] 3. This utility model utilizes the cooperation of the mounting block, the limiting slot, and the rectangular limiting rod. During the impurity removal operation, after the baffle and push plate push out the impurities and return to their original positions, the vibration of the impurity removal machine body, which is connected to the baffle and push plate, can easily cause them to move out of the impurity container frame, affecting the operation of the device. Therefore, a rotatable rectangular limiting rod is provided on the connecting rod. The operator rotates the rectangular limiting rod and makes it correspond to and engage with the limiting slot, forming a locking structure that restricts the baffle and push plate to the designated position, making the impurity removal process more stable.

[0022] 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.

[0023] like Figures 1 to 5As shown, a raw material impurity removal device for biomass pellet fuel production includes an impurity removal machine body 1 and an impurity removal screen 2 connected to the impurity removal machine body 1. A rectangular mounting plate 3 is fixedly connected to the lower front surface of the impurity removal machine body 1. A rectangular mounting rod 4 is fixedly connected to the front surface of the rectangular mounting plate 3. A track groove 5 is opened on the rectangular mounting rod 4. A raw material holding frame 6 is fixedly connected in the track groove 5. Multiple moving wheels 7 are slidably connected in the impurity removal area of ​​the impurity removal screen 2 in the track groove 5. The same impurity holding frame 8 is fixedly connected to the upper end of the multiple moving wheels 7. The end of the impurity holding frame 8 away from the raw material holding frame 6 is set as an opening. A baffle 12 is slidably connected in the opening.

[0024] like Figures 1 to 5 As shown, when the raw material impurity removal device for biomass pellet fuel production of this utility model is in use, impurities fall into the impurity collection frame 8 during the operation of the device. When it accumulates to about half, the impurity collection frame 8 is pulled away from the impurity removal area of ​​the impurity removal screen 2 by the moving wheel 7 along the track groove 5. Then the baffle 12 is moved out to pour the impurities in the impurity collection frame 8 into other collection areas, which can make the impurity removal area below the impurity removal screen 2 cleaner.

[0025] It is worth noting that the raw material container 6 is located in the discharge area of ​​the impurity removal screen 2, and the upper opening area of ​​the impurity container 8 is larger than the impurity removal area of ​​the impurity removal screen 2, and maintains a distance from the raw material container 6. This allows the impurity container 8 to have an adjustable range of movement. As long as the impurity container 8 is still located in the impurity removal area of ​​the impurity removal screen 2, it is not necessary for the impurity container 8 and the raw material container 6 to be in close contact with each other.

[0026] In addition, the side frame of the impurity container 8 can be set to transparent and marked with scales. Users can set the value corresponding to the position of the impurity as needed. When the impurity is reached or close to the target, the impurity in the impurity container 8 can be removed. There is no need to make the above-mentioned subjective judgment on whether the impurity has reached more than half. The judgment can be made directly according to the scale display, which is more clear.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first handle 9 is fixed to the side surface of the impurity container 8 away from the impurity removal machine body 1.

[0028] Specifically, by setting the first handle 9, it is easier and more convenient to move the impurity container 8. During the dragging process, you can hold the first handle 9 and move it without having to hold the edge of the impurity container 8. First, if the impurity container 8 is full, there may be nowhere to hold it. Second, the impurity container 8 contains dust and other impurities, which are quite dirty. Wearing gloves is fine, but if you don't wear gloves and just hold the edge of the impurity container 8 with your bare hands, your hands will get a lot of dust and become very dirty, which will affect the user experience.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limiting threaded hole 10 is opened on the side surface of the rectangular mounting rod 4 away from the impurity remover body 1. The limiting threaded hole 10 passes through the rotating part of one of the moving wheels 7. The limiting threaded hole 10 is internally threaded to a limiting threaded rod 11. The impurity container frame 8 is threadedly fastened to the impurity removal area of ​​the impurity removal screen 2 by the limiting threaded rod 11.

[0030] Specifically, after the impurities in the impurity container 8 have been emptied, it is first moved back to the impurity removal area of ​​the impurity removal screen 2. Then, within this adjustable range, the limiting threaded hole 10 on the moving wheel 7 is aligned with the limiting threaded hole 10 on the rectangular mounting rod 4. Then, the limiting threaded rod 11 is screwed in and tightened to restrict the position of the impurity container 8 so that it will not move arbitrarily during operation.

[0031] like Figures 1-5 As shown, a push plate 13 is slidably connected inside the side of the impurity container 8 near the raw material container 6. A connecting rod 14 is fixedly connected to the surface of the push plate 13 away from the raw material container 6. The connecting rod 14 passes through the baffle 12 and extends outward. A second handle 15 is fixedly connected to the end of the connecting rod 14 away from the raw material container 6. A triangular cutting strip 16 is fixedly connected to the lower surface of the push plate 13 away from the raw material container 6. The lower surface of the triangular cutting strip 16 is in close contact with the lower inner wall of the impurity container 8.

[0032] Specifically, when the impurity removal machine body 1 is running, impurities fall into the impurity collection frame 8. When it accumulates to about half full, the impurity collection frame 8 is pulled away from the impurity removal area of ​​the impurity removal screen 2. Then, the baffle 12 is pulled, which drives the connecting rod 14 and the push plate 13 to move. The push plate 13 pushes the impurities to other collection areas, which can make the impurity removal area below the impurity removal screen 2 cleaner, reduce the impact of impurity accumulation on the efficiency of the impurity removal screen 2, and make the impurity removal process more stable and efficient. In addition, with the unique tilt angle of the triangular cutting strip 16, it can cut into the impurity pile like a sharp "blade" during the process of the push plate 13 pushing the impurities, cutting the impurities out of the impurity collection frame 8, thus making the inside of the impurity collection frame 8 cleaner. After the impurities in the impurity collection frame 8 have been scraped out, the entire baffle 12, connecting rod 14 and push plate 13 can be removed first. Then, the impurity collection frame 8 is lifted at an angle to pour out any remaining impurities inside, making the inside of the impurity collection frame 8 even cleaner.

[0033] It is worth noting that the triangular cutting strip 16 can be made of wear-resistant alloy material, which makes it more robust during operation and extends its service life. At the same time, the triangular cutting strip 16 can be detachably fixed to the push plate 13 by fastening bolts, which allows for regular replacement and maintenance. Since the push plate 13, baffle 12, connecting rod 14 and triangular cutting strip 16 are connected together, they can all be removed from the impurity container 8 together. Therefore, the triangular cutting strip 16 can also be fixedly connected, which makes the connection more stable. Users can choose the appropriate connection method according to the actual situation.

[0034] Furthermore, since the push plate 13 and the baffle 12, as well as the connecting rod 14 and the triangular cutting strip 16 connecting the two, can be directly pulled out from the impurity container 8, and are themselves detachable connections, they can be pulled out at any time for overall inspection without restriction. If replacement is needed, the entire assembly can be replaced. Replacing one part and then replacing another part if it has a problem is more troublesome and time-consuming. It is better to conduct regular inspections and replace the entire assembly only when problems are detected.

[0035] like Figures 1-5 As shown, the surfaces of the first handle 9 and the second handle 15 are both provided with anti-slip sleeves. By setting anti-slip sleeves, the friction and tactile sensation between the first handle 9 and the second handle 15 and the human body can be increased, making it less likely for the user to slip when pushing the impurity container 8 to move or the baffle 12 and the push plate 13 to move as a whole, making the working process safer and more stable.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting block 17 is fixedly attached to the side surface of the impurity container 8 near the second handle 15. The mounting block 17 is located on one side of the connecting rod 14. A limiting slot 18 is provided on the upper surface of the mounting block 17. A rectangular limiting rod 19 is rotatably connected to the outer wall of the connecting rod 14 in the area where the limiting slot 18 is located. The rectangular limiting rod 19 is adapted to and engaged with the limiting slot 18. The push plate 13 is engaged and limited by the rectangular limiting rod 19 and the mounting block 17 on the impurity container 8.

[0037] Specifically, in the impurity removal operation, after the baffle 12 and push plate 13 push out the impurities and return to their original positions, the vibration of the impurity removal machine body 1 and the two are connected to it can easily cause them to move out of the impurity container 8, affecting the operation of the device. Therefore, a rotatable rectangular limiting rod 19 is provided on the connecting rod 14. The operator rotates the rectangular limiting rod 19 and makes it correspond to and engage with the limiting slot 18, forming a locking structure to limit the baffle 12 and push plate 13 to the designated position, making the impurity removal process more stable.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the outer wall of the rectangular limiting rod 19 and the inner wall of the limiting slot 18 are provided with anti-slip texture. By setting the anti-slip texture, the frictional resistance between the rectangular limiting rod 19 and the limiting slot 18 can be increased, making the limiting effect between the two better and more stable, and improving the stability of the entire device during operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
