Description

Technical Field

[0001] The utility model relates to the technical field of flour processing equipment, in particular to a dust removal device for flour production. Background Art

[0002] Flour is a powder made from wheat. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour.

[0003] When flour is processed, a large amount of dust pollution will be generated, and the dust needs to be dealt with in time, otherwise there will be a risk of explosion when the concentration of flour in the air exceeds the safe value. The existing dust removal device usually includes a dust removal box, and a circular cavity is provided inside the dust removal box. The cavity is provided with a spray structure for water mist precipitation of dust and a scraper for scraping off the lumps attached to the inner wall of the cavity after precipitation. The scraper can clean up the lumps attached to the inner wall of the cavity in time to avoid the lumps from drying and increasing the difficulty of later cleaning. However, the existing dust removal device still has some shortcomings: after the scraper is used to scrape off the lumps attached to the inner wall of the cavity, the scraper cannot be replaced in time, and it can only be replaced after the processing is completed. However, more lumps will accumulate on the scraper over time. If it is not replaced in time, it will affect the cleaning of the lumps on the inner wall of the cavity. Utility Model Content

[0004] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects, a dust removal device for flour production is provided, which can replace the scraper without affecting the dust removal effect and efficiency, thereby avoiding the accumulation of excessive sediment on the scraper, thereby avoiding affecting the scraping effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a dust removal device for flour production, comprising a dust removal box, a dust collecting hopper arranged on the dust removal box and a spray structure arranged in the dust removal box, wherein a circular cavity is arranged in the dust removal box, a cleaning component for cleaning the side wall of the cavity is arranged in the cavity, the cleaning component comprises a rotating shaft rotatably connected to the inside of the cavity and a scraper slidably matched with the cavity along the axial direction of the cavity, the rotating shaft is driven to rotate by a driving mechanism arranged on one side of the dust removal box, one end of the scraper away from the rotating shaft is in contact with the inner wall of the cavity, a placement hole with a diameter greater than the diameter of the cavity and connected to the cavity is opened in the horizontal direction on the dust removal box, one end of the rotating shaft is detachably connected with a cover plate, the cover plate is located in the placement hole and matches the placement hole, a first through groove matching the scraper is arranged on the cover plate, one end of the scraper passes through the first through groove and is flush with the outer surface of the cover plate, a limiting component for limiting the scraper is arranged on one side of the cover plate, and the limiting component is detachably connected to the rotating shaft.

[0006] Compared with the prior art, the beneficial effect of the present scheme is that when the dust in the air is absorbed into the cavity of the dust removal box through the ash collecting hopper, water is sprayed into the cavity through the spray structure, so that the dust reacts with the water to form sediment, and then the rotating shaft is driven to rotate by the driving mechanism, and the rotation of the rotating shaft drives the scraper to rotate, and the scraper scrapes off the sediment remaining on the inner wall of the cavity during the rotation process. After the device has worked for a period of time, the driving mechanism is turned off, the rotating shaft no longer rotates, and the limiting component fixed on the rotating shaft is removed from the rotating shaft so that it no longer limits the scraper, and then the scraper is taken out of the cavity, and a new scraper is placed into the cavity through the first through groove and slidably cooperates with the rotating shaft. After the replacement is completed, the limiting component is fixed to the rotating shaft again to limit the scraper. Through the cooperation of the cover plate, the scraper, the rotating shaft and the limiting component, the scraper can be replaced without affecting the dust removal effect and efficiency, ensuring that the end of the scraper that is in contact with the inner wall of the cavity will not accumulate too much sediment, so that the scraper has a better scraping effect on the sediment dried on the inner wall of the cavity.

[0007] As a preferred embodiment of the utility model, a connecting shaft is provided at one end of the rotating shaft close to the cover plate, the connecting shaft extends out of the placement hole, the cover plate is threadedly connected to the connecting shaft, the limiting assembly includes a limiting block threadedly connected to the connecting shaft, and a second through groove for accommodating the scraper to pass through is opened on the limiting block along its radial direction, and when the limiting block is in a tightened state, the second through groove is in a misaligned state with the first through groove.

[0008] The beneficial effects of this program:

[0009] (1) When it is necessary to limit the position of the scraper disposed in the cavity, tighten the limit block. At this time, the second through groove on the limit block is misaligned with the first through groove on the cover plate. Since one end of the scraper is located in the first through groove, the limit block can limit the scraper in the horizontal direction when it is in the tightened state, preventing it from sliding out of the cavity along the first through groove, thereby failing to scrape off the sediment on the inner wall of the cavity. When it is necessary to replace the scraper, loosen the limit block until the second through groove is aligned with the first through groove, and then pass the scraper through the first through groove and the second through groove and take it out of the cavity. The operation is convenient;

[0010] (2) After use, when it is necessary to clean the entire interior of the cavity, the cover plate that is threadedly connected to the connecting shaft can be loosened so that it can be withdrawn from the placement hole and no longer connected to the rotating shaft, thereby exposing the interior of the cavity and facilitating the cleaning of the entire interior of the cavity.

[0011] As a preferred embodiment of the utility model, two scrapers are symmetrically arranged along the radial direction of the rotating shaft, two first through grooves are symmetrically arranged along the radial direction of the cover plate, and two second through grooves are symmetrically arranged along the radial direction of the limit block.

[0012] The beneficial effects of this solution are as follows: the rotation of the shaft drives the scraper to rotate, and the two scrapers symmetrically arranged along the radial direction of the shaft can simultaneously scrape off the dried deposits on the inner wall of the cavity, ensuring that the inner wall of the cavity can be cleaned more promptly and effectively. The first through groove and the second through groove are both symmetrically arranged in two, which is convenient for replacing the two scrapers separately.

[0013] As a preferred embodiment of the utility model, a water collecting box is provided at the lower end of the dust removal box, a third through groove connected to the water collecting box is opened on the lower side of the cavity, a placement groove is provided on one side of the third through groove in the vertical direction, a scraper part for cleaning the scraper is slidably fitted in the placement groove, a compression spring is fixedly connected between the scraper part and the placement groove, and when the scraper rotates to the lower side of the cavity, the scraper part can be driven to move downward until the scraper part is completely located in the third through groove.

[0014] The beneficial effects of this solution are as follows: when the scraper rotates to contact the scraper part, the scraper part can scrape off the sediment at one end of the scraper and enter the water collecting tank through the third through groove. The scraper part moves downward along the placement groove driven by the scraper until the scraper part is completely located in the third through groove, which will not affect the rotation of the scraper. After the scraper rotates to no longer contact the scraper part, the scraper part moves upward to the initial position driven by the spring, so as to facilitate the next scraping of the sediment on the scraper.

[0015] As a preferred embodiment of the utility model, the scraper portion includes a vertical block slidably matched with the placement groove and a scraper blade located on the upper side of the vertical block and arranged at an angle to the vertical portion, and the scraper blade is inclined toward the direction of the third through groove.

[0016] The beneficial effect of this solution is that the scraper blade is tilted toward the direction of the third through groove. When the scraper blade rotates to contact the scraper blade and continues to rotate, the scraper blade scrapes off the sediment at one end of the scraper blade and makes it enter the water collection tank along the third through groove.

[0017] As a preferred embodiment of the utility model, the spray structure includes a spray pipe and a plurality of spray heads arranged on the spray pipe, a groove is provided on the upper side of the cavity along its axial direction, and the spray pipe and the spray heads are completely located in the groove.

[0018] The beneficial effect of this solution is that the spray pipe and the spray head are both arranged in the groove, which can prevent the scraper from colliding with the spray pipe and the spray head when rotating, thereby avoiding damage. BRIEF DESCRIPTION OF THE DRAWINGS
