Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a raw material filtration device for concrete processing. Background Technology

[0002] Concrete, or simply concrete, is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. When processing and filtering the raw materials of concrete, filtration devices are required.

[0003] In existing technologies, when filtering sand, larger stones need to be removed. After filtration, these larger stones remain on the filter assembly, affecting its subsequent filtration efficiency. This necessitates cleaning the filter assembly, during which feeding must be stopped; otherwise, the raw material will be discharged unfiltered, impacting filtration quality. Furthermore, cleaning wastes considerable time, leading to low filtration efficiency. A raw material filtration device for concrete processing is needed to address these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material filtration device for concrete processing to solve the problems mentioned in the background technology. This utility model has a reasonable structure, can clean impurities without stopping the feeding, saves time, and improves filtration efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a raw material filtration device for concrete processing, comprising: The housing has a feed hopper at its top and a filter assembly located inside the housing on its side wall. The filter assembly is provided in pairs and distributed from top to bottom. The upper side of the inner wall of the housing is provided with a feed pipe connected to the feed hopper. The bottom of the feed pipe is provided with an electric valve located above the uppermost filter assembly. The side wall of the feed pipe is provided with a guide pipe that penetrates the side wall of the housing and is used to guide the raw material to the uppermost filter assembly located below. The side wall of the guide pipe is provided with a guide valve.

[0006] Furthermore, the filter assembly includes a sealing plate disposed on the side wall of the housing, the side wall of the sealing plate being provided with a mesh frame plate located inside the housing, and a filter screen being disposed inside the mesh frame plate; The cross-sectional area of ​​the filter screen is larger than the cross-sectional area of ​​the inner wall of the housing.

[0007] Furthermore, the housing is provided with a conical plate located above each of the filter components and used to divert the raw material flowing out from the electric valve or the guide tube. The sidewall of the conical plate is symmetrically provided with fixed columns connected to the inner wall of the housing.

[0008] Furthermore, a material collection seat is provided on the lower side of the inner wall of the housing, a material collection groove is provided on the top of the material collection seat, and a through hole communicating with the material collection groove is provided on the bottom of the material collection seat; The bottom of the housing is provided with a discharge inclined pipe that communicates with the through hole.

[0009] Furthermore, the side wall of the housing is provided with a transparent observation window for observing the impurities filtered by the filter assembly.

[0010] Furthermore, a vibration motor is provided on the side wall of the housing.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows: When it is necessary to remove and clean impurities from the uppermost filter assembly, the electric valve is closed and the guide valve is opened, allowing the raw material to fall onto the lowermost filter assembly along the guide pipe for filtration.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 As shown, this utility model provides a technical solution: a raw material filtration device for concrete processing, comprising: The housing 1 has a feed hopper 2 on its top and a filter assembly 10 located inside the housing 1 on its side wall. The filter components 10 are arranged in pairs, arranged sequentially from top to bottom. A feed pipe 6, connected to the feed hopper 2, is located on the upper side of the inner wall of the housing 1. An electric valve 7 is located at the bottom of the feed pipe 6, above the uppermost filter component 10. A guide pipe 3, penetrating the side wall of the housing 1, is located on the side wall of the feed pipe 6, guiding the raw material to the uppermost filter component 10. A guide valve 31 is located on the side wall of the guide pipe 3. This design allows for the removal and cleaning of impurities from the uppermost filter component 10 by closing the electric valve 7 and opening the guide valve 31, allowing the raw material to fall along the guide pipe 3 onto the lowermost filter component 10 for filtration. Similarly, when cleaning impurities from the lowermost filter component 10, the electric valve 7 is opened and the guide valve 31 is closed, allowing the raw material to fall onto the uppermost filter component 10 for filtration. This allows for cleaning of impurities without stopping the feed, saving time and improving filtration efficiency.

[0015] Reference Figure 2 , Figure 3 and Figure 4 The filter assembly 10 includes a sealing plate 101 disposed on the side wall of the housing 1, and a mesh frame plate 102 located inside the housing 1 is provided on the side wall of the sealing plate 101, and a filter screen 103 is disposed inside the mesh frame plate 102. The cross-sectional area of ​​the filter screen 103 is larger than the cross-sectional area of ​​the inner wall of the housing 1. This design applies force to the sealing plate 101 in the filter assembly 10, causing the mesh frame plate 102 to detach from the housing 1. The mesh frame plate 102 then causes the filter screen 103 to detach from the housing 1, facilitating the cleaning of impurities on the filter screen 103. The housing 1 has a sealing groove on its side wall that matches the sealing plate 101, and a moving groove inside the housing 1 that matches the mesh frame plate 102. The moving groove is connected to the sealing groove, and the vertical cross-sectional area of ​​the sealing groove is larger than that of the moving groove, facilitating the placement and removal of the mesh frame plate 102. A wing bolt is provided at the connection between the mesh frame plate 102 and the housing 1 as needed to improve the stability of the connection and facilitate placement and removal.

[0016] Reference Figure 2 and Figure 4 The housing 1 contains a conical plate 8 located above each filter assembly 10, used to divert the raw material flowing from the electric valve 7 or the guide pipe 3. The sidewalls of the conical plate 8 are symmetrically equipped with fixing posts 81 connected to the inner wall of the housing 1. This design, through the conical plate 8, facilitates the diversion of raw material to the filter screen 103 on the filter assembly 10 for filtration, preventing raw material accumulation from affecting the filtration effect.

[0017] Reference Figure 3 and Figure 5 A material collection seat 9 is provided on the lower side of the inner wall of the shell 1. A material collection groove 91 is provided on the top of the material collection seat 9, and a through hole 92 connected to the material collection groove 91 is provided on the bottom of the material collection seat 9. The bottom of the housing 1 is provided with a discharge inclined pipe 5 that communicates with the through hole 92. This design allows the filtered raw material to be easily collected at the through hole 92 and then flow out of the housing 1 through the discharge inclined pipe 5 via the collection groove 91 on the collection seat 9, thus facilitating the discharge of the raw material.

[0018] Reference Figure 2 and Figure 3 The housing 1 has a transparent observation window 11 on its side wall for observing the impurities filtered by the filter assembly 10. This design allows for easy observation of the impurities on the filter screen 103 in the filter assembly 10, and the impurities can be cleaned as appropriate.

[0019] Reference Figure 1 A vibration motor 4 is provided on the side wall of the housing 1. This design improves the filtration effect of the filter assembly 10 on the raw materials by using the vibration motor 4, speeds up the filtration of the raw materials, and avoids the raw materials from clogging inside the guide tube 3; wherein, a pair of vibration motors 4 are provided and are respectively located on the opposite side walls of the housing 1.

[0020] Reference Figures 1-5As an embodiment of this utility model: when it is necessary to filter the raw material, the raw material is fed into the feed hopper 2, and discharged from the electric valve 7 along the feed pipe 6. It falls on the conical plate 8 and is diverted to the filter screen 103 on the filter assembly 10 for filtration. The filtered raw material then flows out from the discharge inclined pipe 5 along the collection seat 9.

[0021] When it is necessary to remove and clean the impurities on the uppermost filter assembly 10, close the electric valve 7 and open the guide valve 31. The raw material falls onto the lowermost filter assembly 10 along the guide pipe 3 for filtration. Then, force is applied to the sealing plate 101 in the uppermost filter assembly 10, causing the mesh frame plate 102 on it to detach from the housing 1. The filter screen 103 follows the mesh frame plate 102 out of the housing 1, making it convenient to clean the impurities on the uppermost filter assembly 10.

[0022] Similarly, when it is necessary to clean the impurities on the bottom filter assembly 10, the electric valve 7 is opened and the guide valve 31 is closed. The raw material flows out from the electric valve 7 and falls onto the top filter assembly 10 for filtration. Then, force is applied to the sealing plate 101 in the bottom filter assembly 10, causing the mesh frame plate 102 on it to detach from the housing 1. The filter screen 103 follows the mesh frame plate 102 and detaches from the housing 1, making it convenient to clean the impurities on the bottom filter assembly 10. The two filter assemblies 10 clean the impurities alternately, realizing the cleaning of impurities without stopping the feeding, saving time, improving filtration efficiency, and enhancing the practicality of this utility model.
