Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a layered screening device for flour processing. Background Technology

[0002] Flour is a powdery substance made from wheat. Based on the protein content, flour can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour (wheat flour) is a staple food in most parts of northern China. There are many kinds of food made from flour. Flour processing plants produce flour from wheat and sell it all over the country. The fineness of flour is also one of the options for classifying different qualities, which requires the use of a layered screening device in the flour processing process.

[0004] Based on the above patent search and the findings of existing equipment, while the aforementioned equipment can solve the problem of general flour processing layered screening devices being inconvenient to inspect and maintain, resulting in excessively high maintenance costs and increased flour processing costs, thus raising the market price of flour to some extent, and therefore failing to better meet current user needs, the layered filtration device lacks an external connection device. When adding flour to the screening box, the absence of an air venting device inside the screening box easily leads to significant flour leakage from the feed inlet. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a layered screening device for flour processing, which has the advantage of auxiliary dust removal. It solves the problem that the layered filtration device does not have a device to connect with the outside world, and when flour is added to the screening box, the flour at the feed inlet is prone to serious leakage because there is no extra air discharge device inside the screening box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a layered screening device for flour processing, comprising a mounting box, a base plate, a screening box, and a feed pipe. The top of the mounting box is fixedly connected to the bottom of the base plate, the top of the base plate is fixedly connected to the bottom of the screening box, the rear side of the top of the screening box is fixedly connected to the bottom of the feed pipe, the feed pipe is connected to the rear side of the top of the inner wall of the screening box, a connecting groove is provided on the front of the screening box, a filter plate is slidably connected to the inner wall of the connecting groove, a dust removal component is movably connected to the front of the screening box, and mounting components are fixedly connected to both sides of the front of the screening box.

[0007] As a preferred embodiment of this utility model, the dust removal component includes a fixed box, the back of which is movably connected to the front of the screening box, and electrostatic dust removal rods are movably connected to both sides of the inner wall of the fixed box.

[0008] As a preferred embodiment of this utility model, the mounting component includes a mounting strip, the back of which is fixedly connected to both sides of the front of the screening box, and mounting grooves are provided on both sides of the back of the fixed box, with the inner wall of the mounting groove slidably connected to the surface of the mounting strip.

[0009] As a preferred embodiment of this utility model, clamping rings are fixedly connected to the top and bottom of both sides of the inner wall of the fixed box, and the inner wall of the clamping rings is engaged with both sides of the surface of the electrostatic dust removal rod.

[0010] As a preferred embodiment of this utility model, slots are provided on both sides of the top and bottom of the inner wall of the connecting groove, and a locking block is slidably connected to the inner wall of the slot. The inner side of the locking block is fixedly connected to both sides of the top and bottom of the filter plate.

[0011] As a preferred embodiment of this utility model, both sides of the fixed box are provided with sliding grooves, and a slider is slidably connected to the inner wall of the sliding groove. A scraper is movably sleeved on the top of the surface of the electrostatic dust removal rod, and the outer side of the scraper is fixedly connected to the inner side of the slider.

[0012] As a preferred embodiment of this utility model, an auxiliary groove is provided on the left side of the screening box, and a cover plate is movably connected to the rear side of the inner wall of the auxiliary groove via a shaft pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a connecting groove and a filter plate, allows the air inside the screening box to exchange with the air outside the screening box, making the air pressure inside the screening box equal to that outside. The filter plate reduces the escape of dust from inside the screening box. This solves the problem that the previous layered filtration device did not have a device to connect with the outside, and when flour was added to the screening box, the lack of an excess air exhaust device made it easy for flour to escape from the feed inlet. This achieves the effect of auxiliary dust removal.

[0015] 2. This utility model, by setting up a dust removal component, allows the user to connect the filter plate to the screening box, align the fixed box with the connecting groove, and keep it in the connecting groove. The electrostatic dust removal rod inside the fixed box is used to draw in the dust that escapes through the filter plate, thereby reducing the dust content in the air and achieving the effect of reducing dust escape from the screening box.

[0016] 3. By setting up an installation component, when the user needs to connect the fixing box to the screening box, the mounting groove at the bottom of the back of the fixing box is aligned with the top of the mounting strip, and then the fixing box is moved downwards so that the mounting strip is completely moved into the inside of the mounting groove. The mounting strip can restrict the movement direction of the fixing box, so that the fixing box can be placed at the outlet of the connecting groove, thereby achieving the effect of assisting the user in installing the fixing box.

[0023] like Figures 1 to 4 As shown, the present invention provides a layered screening device for flour processing, including a mounting box 1, a bottom plate 2, a screening box 3, and a feed pipe 4. The top of the mounting box 1 is fixedly connected to the bottom of the bottom plate 2, the top of the bottom plate 2 is fixedly connected to the bottom of the screening box 3, the rear side of the top of the screening box 3 is fixedly connected to the bottom of the feed pipe 4, the feed pipe 4 is connected to the rear side of the top of the inner wall of the screening box 3, a connecting groove 5 is provided on the front of the screening box 3, a filter plate 6 is slidably connected to the inner wall of the connecting groove 5, a dust removal component 7 is movably connected to the front of the screening box 3, and mounting components 8 are fixedly connected to both sides of the front of the screening box 3.

[0024] refer to Figure 4 The dust removal assembly 7 includes a fixed box 71, the back of which is movably connected to the front of the screening box 3, and electrostatic dust removal rods 72 are movably connected to both sides of the inner wall of the fixed box 71.

[0025] As a technical optimization of this utility model, by setting up a dust removal component 7, after the user connects the filter plate 6 to the screening box 3, the fixed box 71 is aligned with the connecting groove 5 and placed at the connecting groove 5. The electrostatic dust removal rod 72 inside the fixed box 71 is used to draw in the dust that escapes through the filter plate 6, thereby reducing the dust content in the air and achieving the effect of reducing the dust escape from the screening box 3.

[0026] refer to Figure 3 The mounting component 8 includes a mounting strip 81. The back of the mounting strip 81 is fixedly connected to both sides of the front of the screening box 3. The back of the fixed box 71 has mounting grooves 82 on both sides. The inner wall of the mounting groove 82 is slidably connected to the surface of the mounting strip 81.

[0027] As a technical optimization of this utility model, by setting the installation component 8, when the user needs to connect the fixing box 71 to the screening box 3, the mounting groove 82 at the bottom of the back of the fixing box 71 is aligned with the top of the mounting strip 81, and then the fixing box 71 is moved downward so that the mounting strip 81 is completely moved into the interior of the mounting groove 82. The mounting strip 81 can restrict the movement direction of the fixing box 71, so that the fixing box 71 can be placed at the outlet of the connecting groove 5, thereby achieving the effect of assisting the user in installing the fixing box 71.

[0028] refer to Figure 4The top and bottom of both sides of the inner wall of the fixed box 71 are fixedly connected with clamping rings 9, and the inner wall of the clamping rings 9 is engaged with both sides of the surface of the electrostatic dust removal rod 72.

[0029] As a technical optimization of this utility model, by setting clamping rings 9, when the user needs to fix the electrostatic dust removal rod 72 to both sides of the inner wall of the fixing box 71, either end of the surface of the electrostatic dust removal rod 72 can be moved to the inner wall of the clamping ring 9, and then the other end of the electrostatic dust removal rod 72 can be moved to the inner wall of another clamping ring 9. The clamping rings 9 can fix the electrostatic dust removal rod 72 to both sides of the inner wall of the fixing box 71. When the user needs to repair the electrostatic dust removal rod 72, he / she only needs to remove the electrostatic dust removal rod 72 from the clamping ring 9, thereby achieving the effect of facilitating the user to install the electrostatic dust removal rod 72.

[0030] refer to Figure 3 The inner wall of the connecting groove 5 has slots 10 on both sides of the top and bottom. The inner wall of the slot 10 is slidably connected to a block 11. The inner side of the block 11 is fixedly connected to the top and bottom sides of the filter plate 6.

[0031] As a technical optimization of this utility model, by setting the slot 10 and the block 11, when the user needs to install the filter plate 6 into the interior of the connecting groove 5, the block 11 on the top and bottom sides of the filter plate 6 is aligned with the slot 10, and then the filter plate 6 is moved towards the screening box 3 so that the block 11 is completely moved into the interior of the slot 10. Then the fixing box 71 is connected to the screening box 3. With the fixing box 71, the block 11 cannot be moved out of the slot 10. The slot 10 allows the filter plate 6 to be placed more stably inside the connecting groove 5, thereby achieving the effect of assisting the installation of the filter plate 6.

[0032] refer to Figure 3 and Figure 4 Both sides of the fixed box 71 are provided with sliding grooves 12, and the inner wall of the sliding groove 12 is slidably connected to the slider 13. The top of the surface of the electrostatic dust removal rod 72 is movably fitted with a scraper 14, the outer side of the scraper 14 is fixedly connected to the inner side of the slider 13, and the outer side of the slider 13 is fixedly connected to an auxiliary block 15.

[0033] As a technical optimization of this utility model, by setting up a sliding groove 12, a sliding block 13, a scraper 14, and an auxiliary block 15, as the electrostatic dust removal rod 72 is used for a long time, a large amount of dust will adhere to the surface of the electrostatic dust removal rod 72. At this time, the auxiliary block 15 is pressed down. Since the sliding block 13 is fixedly connected to the auxiliary block 15, the sliding block 13 will move downward with the auxiliary block 15. The auxiliary block 15 can increase the contact area between the user and the sliding block 13, making it easier for the user to move the sliding block 13. The sliding groove 12 can limit the movement direction of the sliding block 13, making the movement of the sliding block 13 more stable. At the same time, the sliding block 13 is fixedly connected to the scraper 14, so that the scraper 14 will also move downward with the sliding block 13. The scraper 14 can scrape off the dust on the surface of the electrostatic dust removal rod 72, thereby achieving the effect of assisting in scraping off the dust on the surface of the electrostatic dust removal rod 72.

[0034] refer to Figure 2 An auxiliary groove 16 is provided on the left side of the screening box 3, and a cover plate 17 is movably connected to the rear side of the inner wall of the auxiliary groove 16 via a shaft pin.

[0035] As a technical optimization of this utility model, by setting an auxiliary groove 16 and a cover plate 17, when the user needs to replace the storage device inside the screening box 3, the corresponding cover plate 17 is flipped to the left side of the screening box 3 to expose the corresponding storage device, which makes it easier for the user to move the storage device inside the screening box 3, thereby achieving the effect of assisting the use of the screening box 3.

[0036] The working principle and usage process of this utility model are as follows: During use, the connecting groove 5 allows for air exchange between the inside and outside of the screening box 3, ensuring the air pressure inside and outside the screening box 3 is equal. The filter plate 6 reduces dust escape from the screening box 3. When the user needs to connect the filter plate 6 to the inside of the connecting groove 5 via the mounting groove 82, align the locking blocks 11 on the top and bottom sides of the filter plate 6 with the locking slots 10, and then move the filter plate 6 towards the screening box 3 until the locking blocks 11 are fully inside the locking slots 10. Next, connect the fixing box 71 to the screening box 3. First, align the mounting groove 82 on the bottom back of the fixing box 71 with the top of the mounting strip 81, then move the fixing box 71 downwards until the mounting strip 81 is fully inside the mounting groove 82. The mounting strip 81 restricts the movement direction of the fixing box 71. The fixing box 71 can be placed at the outlet of the connecting groove 5. The fixing box 71 prevents the locking block 11 from moving out of the locking groove 10. The locking groove 10 allows the filter plate 6 to be placed more stably inside the connecting groove 5. The electrostatic dust removal rod 72 inside the fixing box 71 is used to attract the dust that escapes through the filter plate 6, thereby reducing the dust content in the air. When the user needs to install the electrostatic dust removal rod 72 on both sides of the inner wall of the fixing box 71 in the mounting groove 82, one end of either side of the surface of the electrostatic dust removal rod 72 is moved to the inner wall of the clamping ring 9, and then the other end of the electrostatic dust removal rod 72 is moved to the inner wall of the other clamping ring 9. The clamping ring 9 can fix the electrostatic dust removal rod 72 on both sides of the inner wall of the fixing box 71. When the user needs to repair the electrostatic dust removal rod 72, he / she only needs to remove the electrostatic dust removal rod 72 from the clamping ring 9, thereby achieving the effect of auxiliary dust removal.

[0037] In summary, this layered screening device for flour processing, by setting up a connecting groove 5 and a filter plate 6, allows the air inside the screening box 3 to exchange with the air outside the screening box 3, making the air pressure inside the screening box 3 equal to that outside. The filter plate 6 further reduces the amount of dust escaping from inside the screening box 3. This solves the problem that the layered filtration device did not have a device to connect with the outside, and when adding flour to the screening box, the lack of an excess air venting device made it easy for flour to escape from the feed inlet.
