A device for pretreating a wheat raw material before grinding

Abstract

This utility model discloses a pretreatment device for wheat raw materials before grinding, relating to the field of wheat processing technology. It includes a feeding box, on the surface of which a grinding mill housing is fixedly installed. An outer frame is slidably installed on the surface of the feeding box, and a magnetic plate is slidably installed on the inner side of the outer frame. A magnetic column is fixedly installed on the inner side of the outer frame away from the magnetic plate. In this pretreatment device, the wheat raw materials at the filter screen support plate allow iron filings inside to be adsorbed and cleaned by the magnetic plate through their own mesh. Simultaneously, the magnetic column on the outer frame forms abutment against the inside of the wheat raw materials. This achieves not only the effect of adsorbing and cleaning iron filings as the wheat raw materials pass through the feeding box, but also the effect of agitating the wheat raw materials to adsorb iron filings through the magnetic column. This improves the convenience of iron filings cleaning before grinding, and the simultaneous adsorption of iron filings by the upper and lower parts of the wheat raw materials ensures the reliability of the cleaning process.

Description

Technical Field

[0001] This utility model relates to the field of wheat processing technology, and in particular to a pretreatment device for wheat raw materials before grinding. Background Technology

[0002] Wheat flour is flour processed from wheat, generally referring to flour after the bran has been removed. The processing of wheat flour requires the use of grinding equipment to grind the wheat raw material.

[0003] Most wheat raw materials require impurity removal before grinding, especially iron filings, to ensure a good texture after grinding. Although most wheat raw materials pass through magnets in the conveying channel before grinding to remove iron filings, some magnets are not directly bonded to the material and have insufficient contact area with the wheat. This results in poor adsorption and a poor texture when the wheat passes through the magnets. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pretreatment device for wheat raw material grinding, comprising a feeding box, a grinding machine box fixedly installed on the surface of the feeding box, an outer cover frame slidably installed on the surface of the feeding box, a magnet plate slidably installed on the inner side of the outer cover frame, a magnet column fixedly installed on the inner side of the outer cover frame away from the magnet plate, a filter screen support plate slidably installed on the surface of the feeding box, and a limit block fixedly installed on the surface of the feeding box.

[0006] Preferably, the inner side of the conveying box is provided with an extension groove, and the surface of the magnet column is slidably mounted on the inner wall of the extension groove.

[0007] Preferably, the outer frame surface is inclined, and an auxiliary ball is rotatably mounted on the surface of the outer frame.

[0008] Preferably, the surface of the filter support plate is provided with a docking groove, and a docking column is slidably installed on the inner wall of the docking groove. The surface of the docking column is fixedly installed on the surface of the feed box.

[0009] Preferably, the surface of the outer frame is provided with a positioning support groove, and a positioning support plate is slidably installed on the inner wall of the positioning support groove.

[0010] Preferably, a guide frame is fixedly installed on the surface of the feeding box, and the inner side of the guide frame is also inclined. A support frame is fixedly installed on the side of the guide frame away from the magnet plate.

[0011] Preferably, the surface of the docking post is also inclined.

[0012] Preferably, a limiting support rod is slidably installed on the inner side of the positioning support plate, and the end of the limiting support rod away from the positioning support plate is fixedly installed on the inner side of the material conveying box. The internal thread of the limiting support rod is fitted with a positioning bolt.

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

[0014] (1) In this pretreatment device for wheat raw material grinding, the wheat raw material can be cleaned by adsorbing iron filings inside the filter screen support plate through its own mesh. At the same time, the magnetic column on the outer frame forms abutment against the inside of the wheat raw material, so that when the wheat raw material passes through the conveying box, it not only has the effect of adsorbing and cleaning iron filings, but also has the effect of moving the wheat raw material to adsorb iron filings through the magnetic column. This improves the convenience of cleaning iron filings before grinding the wheat raw material, and the reliability of cleaning is ensured by adsorbing iron filings on the wheat raw material simultaneously from the upper and lower positions. This improves the disadvantage of the traditional method of cleaning wheat raw material by adsorbing and cleaning only through a single round magnetic plate before grinding. Furthermore, the simple separation operation between the outer frame and the conveying box ensures the high efficiency of separation and cleaning after the magnetic plate has been adsorbed for a certain period of time.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a pretreatment device for wheat raw material grinding, including a feeding box 1, a grinding box 2 fixedly installed on the surface of the feeding box 1, and the grinding box 2 grinding the wheat raw material conveyed by the feeding box 1.

[0028] Furthermore, a guide frame 3 is fixedly installed on the surface of the feeding box 1. The inner side of the guide frame 3 is inclined. A support frame 4 is fixedly installed on the side of the guide frame 3 away from the magnet plate 10. The function of the guide frame 3 is to feed wheat raw materials, while the support frame 4 at the guide frame 3 provides support for the wheat raw materials so that the operator can control the feeding of the wheat raw materials.

[0029] Furthermore, an outer cover frame 5 is slidably mounted on the surface of the material conveying box 1. A positioning support groove 6 is provided on the surface of the outer cover frame 5. A positioning support plate 7 is slidably mounted on the inner wall of the positioning support groove 6. A limiting support rod 8 is slidably mounted on the inner side of the positioning support plate 7. The end of the limiting support rod 8 away from the positioning support plate 7 is fixedly mounted on the inner side of the material conveying box 1. A positioning bolt 9 is installed in the internal thread of the limiting support rod 8. When it is necessary to install and assemble the outer cover frame 5 and the material conveying box 1, the positioning bolt 9 only needs to be screwed downward on the surface of the limiting support rod 8, so that the positioning bolt 9 forms a limiting block on the positioning support plate 7, thereby realizing the installation and positioning between the outer cover frame 5 and the material conveying box 1. When it is necessary to remove the outer cover frame 5 from the surface of the material conveying box 1, the operator only needs to control the positioning bolt 9 to adjust the inner thread of the limiting support rod 8 to disengage. At this time, the positioning support plate 7 can be adjusted on the surface of the limiting support rod 8, so that the positioning support plate 7 no longer forms a block on the outer cover frame 5. Thus, the separation operation between the outer cover frame 5 and the material conveying box 1 is simplified.

[0030] Furthermore, a magnetic plate 10 is slidably installed on the inner side of the outer frame 5, and a magnetic column 11 is fixedly installed on the inner side of the outer frame 5 away from the magnetic plate 10. An extension groove 12 is opened on the inner side of the feeding box 1, and the surface of the magnetic column 11 is slidably installed on the inner wall of the extension groove 12. A filter screen support plate 13 is slidably installed on the surface of the feeding box 1, and a limit block 14 is fixedly installed on the surface of the feeding box 1. The surface of the outer frame 5 is also inclined. The inclined state of the outer frame 5 ensures the accuracy of the docking with the feeding box 1. When the wheat raw material reaches the feeding box 1 at the guide frame 3, the iron filings inside the wheat raw material can pass through the magnetic plate 10 through its own mesh at the filter screen support plate 13. During the adsorption and cleaning process, the magnetic pillars 11 on the outer frame 5 abut against the inside of the wheat raw material. This ensures that the wheat raw material not only has the effect of adsorbing and cleaning iron filings as it passes through the conveying box 1, but also has the effect of moving the wheat raw material to adsorb iron filings through the magnetic pillars 11. This improves the convenience of iron filings cleaning before grinding the wheat raw material, and the reliability of the cleaning is ensured by adsorbing iron filings on the wheat raw material simultaneously from the upper and lower positions. This improves the shortcomings of traditional wheat raw material cleaning by adsorbing and cleaning with only a single round magnetic plate 10 before grinding. Furthermore, the simple separation operation between the outer frame 5 and the conveying box 1 ensures the high efficiency of separation and cleaning after the magnetic plate 10 has adsorbed for a certain period of time.

[0031] Furthermore, an auxiliary ball 15 is rotatably mounted on the surface of the outer frame 5, and a docking groove 16 is opened on the surface of the filter support plate 13. A docking post 17 is slidably mounted on the inner wall of the docking groove 16. The surface of the docking post 17 is also inclined. The surface of the docking post 17 is fixedly mounted on the surface of the feed box 1. After the filter support plate 13 is cleaned regularly, the filter support plate 13 and the docking post 17 can be docked and installed. The inclined state of the docking post 17 ensures the convenience of assembly when the filter support plate 13 and the docking post 17 are docked. The auxiliary ball 15 on the magnet plate 10 ensures the smoothness of the sliding adjustment of the outer frame 5 and the feed box 1.

[0032] Working principle: A pretreatment device for wheat raw material before grinding. When the wheat raw material arrives at the conveying box 1 at the guide frame 3, the iron filings inside the wheat raw material can be adsorbed and cleaned by the magnetic plate 10 through its own mesh at the filter support plate 13. At the same time, the magnetic column 11 on the outer frame 5 forms abutment against the inside of the wheat raw material, so that when the wheat raw material passes through the conveying box 1, it not only has iron filings adsorbed and cleaned, but also has iron filings adsorbed by the magnetic column 11.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
