Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, in particular to a flour purifier for flour processing. Background Art

[0002] A flour purifier is a type of grain processing machinery that separates pure and relatively pure endosperm particles from the materials ground by a flour mill. It consists of a sieve body equipped with a double-path, two-layer sieve surface or a double sieve body equipped with two or three layers of sieve surfaces, equipped with air ducts, air chambers, etc. Each layer of sieve surface is composed of four sieve grids equipped with different screens connected in series. The sieve body is supported by two pairs of rubber springs at the front and rear, and is driven by an eccentric or inertial force transmission mechanism to perform a throwing motion. The airflow passes through two or three layers of sieve surfaces from the bottom of the sieve body upward and enters 8 to 16 divided small air chambers on the top of the sieve body. The air volume of each air chamber can be adjusted separately. The combined effect of vibration, screen mesh and airflow can loosen the material entering the flour purifier and roughly divide it into six layers according to specific gravity, particle shape, surface properties and aerodynamic characteristics. The light bran is sucked away, and the endosperm with skin is output as the screen-over material; the pure and relatively pure endosperm particles enter the flour mill as the screen-under material and are further ground into special or superior flour.

[0003] After searching, the Chinese patent publication number CN216965397U discloses a flour purifier for flour processing, which mainly uses a lifting component to separate the abutment plate from the discharge port, and uses the elastic force of the second spring to make the cover plate cover the top of the collection container.

[0004] By comparing with the existing technologies in related fields, it can be seen that when the screen is screening materials, a brush will be used to clean the screen. When using the brush for cleaning, the material stuck in the screen holes cannot be effectively cleaned. The material is stuck in the screen holes, affecting the use of the screen. After a long period of friction, the brush will fall off and fall into the material, causing pollution and affecting the quality of the flour. Utility Model Content

[0005] The purpose of the utility model is to provide a flour purifier for flour processing in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A flour purifier for flour processing comprises a lower body, an upper body is slidably mounted on the lower body, a vibration assembly is mounted on the side of the lower body, a material discharge assembly is arranged on the lower surface of the lower body, a filter assembly and a cleaning unit are equidistantly and cross-arranged inside the lower body, a feed pipe and an air extraction assembly are arranged on the upper body, the filter assembly, the vibration assembly, the material discharge assembly and the air extraction assembly work by adopting the existing technology, the lower body and the upper body are connected by adopting the existing method, the feed pipe is connected with the external material feeding device, the external feeding device conveys the material into the lower body and the upper body through the feed pipe, the material falls onto the filter assembly, the vibration assembly causes the lower body and the upper body to shake, thereby causing the material on the filter assembly to vibrate, the material is screened by the filter assembly, the material is air-selected by the air extraction assembly, the processed material is led out and collected by the material discharge assembly, and during the material screening process, the filter assembly is cleaned by the cleaning unit to avoid the filter assembly from being blocked, thereby ensuring the filtering quality and filtering speed of the filter assembly on the material;

[0008] The cleaning unit includes a telescopic assembly and a crossbeam. The telescopic assembly is arranged at equal distances on the side of the lower body. The crossbeam is installed at equal distances on the part of the telescopic assembly located in the lower body. The upper surface of the crossbeam is arranged at equal distances. The lower surface of the crossbeam is arranged with an upper support rod. The lower surface of the crossbeam is arranged with a connecting rod and a lower support rod. A guide plate is arranged at the lower end of the connecting rod. The guide plate is slidably connected to the upper surface of the filter assembly and the lower body. The lengths of the upper support rod and the lower support rod installed on the crossbeam are different. The telescopic assembly drives the upper support rod, the lower support rod and the guide plate to reciprocate on the filter assembly through the crossbeam, and the material on the filter assembly is turned up by the guide plate to complete the turning of the material, so that small particles in the material can be removed. Particulate materials can be screened out better. At the same time, since the lengths of the upper support rod and the lower support rod are different, when the upper support rod and the lower surface of the filter assembly, and the lower support rod and the upper surface of the filter assembly are in contact, the filter assembly is deformed to varying degrees through the upper support rod and the lower support rod. Since the filter assembly itself has a certain elasticity, the filter assembly can automatically recover after being deformed by force. Through the different degrees of deformation of the filter assembly, the material in the filter holes of the filter assembly can be better removed, effectively improving the efficiency and quality of the filter assembly cleaning, reducing the blockage of the filter assembly, ensuring the normal operation of the filter assembly, and avoiding the pollution of the material caused by using a brush to clean.

[0009] Furthermore, the telescopic assembly on the side of the lower body includes a hydraulic cylinder and a guide rod. The hydraulic cylinder is installed on the side of the lower body. The hydraulic cylinder and the filter assembly are cross-arranged. The telescopic end of the hydraulic cylinder is connected to the guide rod. The telescopic end of the hydraulic cylinder is slidably connected to the lower body. The guide rod is connected to the crossbeam. The hydraulic cylinder and the external controller are electrically connected. The hydraulic cylinder works using existing technology, and the hydraulic cylinder drives the crossbeam to move through the guide rod.

[0010] Furthermore, a ball is rotatably installed at the end of the beam, and the ball is slidably connected to the lower body. The ball reduces the friction between the lower body and the beam, and the ball enables the beam to move better along the lower body.

[0011] Furthermore, a crushing unit is installed in the feed pipe, and the crushing unit includes a support plate, which is arranged in the upper body and located directly below the feed pipe. A motor is installed on the support plate, and the motor is connected to a main shaft. The main shaft rotates to connect the support plate and the feed pipe. A crushing knife is installed on the part of the main shaft located in the feed pipe. The motor is electrically connected to an external controller, and the motor works using existing technology. The motor drives the crushing knife through the main shaft to crush the material in the feed pipe, so that the material is dispersed into the upper body, effectively preventing the material from agglomerating and affecting the screening efficiency.

[0012] Furthermore, a bulk plate is provided on the part of the main shaft located in the upper body, and the bulk plate is conical. A baffle is provided at a position in the upper body corresponding to the bulk plate. The conical bulk plate is used to disperse the material entering the upper body in a circumferential direction so that the material enters the upper body evenly. The baffle cooperates with the upper body to limit the material on the bulk plate so that the material on the bulk plate is dispersed at a certain position in the upper body.

[0013] Furthermore, an observation window is provided on the side of the upper body, and a transparent plate is installed in the observation window, so that the interior of the upper body can be observed conveniently through the observation window and the transparent plate.

[0014] Furthermore, a scraper is installed at the end of the crossbeam in the middle of the guide rod, and the scraper is slidably connected to the transparent plate, so that the transparent plate is cleaned by the scraper.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] 1. The upper support rod, the lower support rod and the guide plate are driven to move back and forth on the filter assembly by the hydraulic cylinder, the guide rod and the crossbeam. The material on the filter assembly is turned up by the guide plate to complete the turning of the material, so that the small particles in the material can be better screened out by the suction assembly. At the same time, since the lengths of the upper support rod and the lower support rod are different, the filter assembly is deformed to different degrees by the upper support rod and the lower support rod. Through the deformation and restoration of the filter assembly to different degrees, the material in the filter hole of the filter assembly can be better removed, effectively avoiding the clogging of the filter hole of the filter assembly by the material, improving the efficiency and quality of the filter assembly cleaning, ensuring the normal operation of the filter assembly, and avoiding the pollution of the material when cleaning with a brush.

[0017] 2. The materials in the feed pipe are crushed by the motor, spindle and crushing knife, which effectively prevents the material from agglomerating and affecting the screening efficiency. The materials are dispersed into the feed pipe through the bulk plate, which effectively prevents the material from piling up and affecting the screening efficiency.

[0029] like Figure 1-Figure 8 As shown, a flour purifier for flour processing comprises a lower body 1, an upper body 2 is slidably mounted on the lower body 1, a vibration assembly 6 is mounted on the side of the lower body 1, a material discharge assembly 8 is arranged on the lower surface of the lower body 1, a filter assembly 13 and a cleaning unit 3 are equidistantly and cross-arranged inside the lower body 1, a feed pipe 5 and an air extraction assembly 7 are arranged on the upper body 2, the filter assembly 13, the vibration assembly 6, the material discharge assembly 8 and the air extraction assembly 7 work using the existing technology, the lower body 1 and the upper body 2 are connected in an existing manner, and the feed pipe 5 is connected to an external feeding device, such as Figure 3-Figure 5 , Figure 7 , Figure 8 As shown, the external conveying device conveys the material into the lower body 1 and the upper body 2 through the feed pipe 5, and the material falls onto the filter assembly 13. The vibration assembly 6 causes the lower body 1 and the upper body 2 to shake, thereby causing the material on the filter assembly 13 to vibrate, so that the material is screened by the filter assembly 13. During the material screening process on the filter assembly 13, the fine particles in the material are air-selected by the exhaust assembly 7 and extracted by the exhaust assembly 7. The processed material is led out and collected by the discharge assembly 8. During the material screening process, the filter assembly 13 is cleaned by the cleaning unit 3 to avoid clogging of the filter assembly 13, thereby ensuring the filtering quality and filtering speed of the filter assembly 13 for the material;

[0030] The cleaning unit 3 includes a telescopic assembly and a crossbeam 33. The telescopic assembly is arranged at equal distances on the side of the lower body 1. The crossbeam 33 is installed at equal distances on the part of the telescopic assembly located in the lower body 1. The upper surface of the crossbeam 33 is provided with upper support rods 34 at equal distances. The lower surface of the crossbeam 33 is provided with connecting rods 35 and lower support rods 37 at equal distances. The lower end of the connecting rod 35 is provided with a guide plate 36. The guide plate 36 is slidably connected to the upper surface of the filter assembly 13 and the lower body 1. The lengths of the upper support rod 34 and the lower support rod 37 installed on the crossbeam 33 are different. Figure 1-Figure 3 , Figure 5 , Figure 8As shown, the telescopic assembly drives the crossbeam 33 to reciprocate in the lower body 1, and the crossbeam 33 drives the upper support rod 34, the lower support rod 37 and the guide plate 36 to reciprocate on the filter assembly 13. During the movement, the guide plate 36 turns up the material on the filter assembly 13 to complete the turning of the material, so that the small particles in the material can be better screened out through the suction assembly 7, and the material on the filter assembly 13 is pushed, so that the material can be better screened. At the same time, since the lengths of the upper support rod 34 and the lower support rod 37 are different, the lower surface of the upper support rod 34 and the filter assembly 13 When the lower support rod 37 contacts the upper surface of the filter assembly 13, the filter assembly 13 is deformed to varying degrees through the upper support rod 34 and the lower support rod 37. Since the filter assembly 13 itself has a certain elasticity, the filter assembly 13 can automatically recover after being deformed by force. Through the deformation and recovery of the filter assembly 13 to varying degrees, the material in the filter holes of the filter assembly 13 can be better removed, and the clogging of the filter holes of the filter assembly 13 by the material can be effectively avoided, thereby improving the cleaning efficiency and quality of the filter assembly 13, ensuring the normal operation of the filter assembly 13, and avoiding contamination of the material when cleaning with a brush.

[0031] The telescopic assembly on the side of the lower body 1 includes a hydraulic cylinder 31 and a guide rod 32. The hydraulic cylinder 31 is installed on the side of the lower body 1. The hydraulic cylinder 31 and the filter assembly 13 are arranged crosswise. The telescopic end of the hydraulic cylinder 31 is connected to the guide rod 32. The telescopic end of the hydraulic cylinder 31 is slidably connected to the lower body 1. The guide rod 32 is connected to the crossbeam 33. The hydraulic cylinder 31 is electrically connected to the external controller. The hydraulic cylinder 31 works using existing technologies, such as Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, the guide rod 32 is driven to move in the lower body 1 by the hydraulic cylinder 31 , and the cross beam 33 is driven to move in the lower body 1 by the guide rod 32 , so that the position of the cross beam 33 in the lower body 1 is adjusted.

[0032] The end of the cross beam 33 is rotatably mounted with a ball 12, and the ball 12 is slidably connected to the lower body 1. Figure 2 , Figure 6 As shown, during the movement of the cross beam 33 in the lower body 1 , the friction between the lower body 1 and the cross beam 33 is reduced by the ball bearings 12 , and the cross beam 33 can be moved better along the lower body 1 by the ball bearings 12 .

[0033] A crushing unit 4 is installed in the feed pipe 5. The crushing unit 4 includes a support plate 41. The support plate 41 is arranged in the upper body 2. The support plate 41 is located directly below the feed pipe 5. A motor 42 is installed on the support plate 41. The motor 42 is connected to a main shaft 43. The main shaft 43 is rotatably connected to the support plate 41 and the feed pipe 5. A crushing knife 44 is installed on the part of the main shaft 43 located in the feed pipe 5. The motor 42 is electrically connected to an external controller. The motor 42 works using existing technologies, such as Figure 3 , Figure 4 As shown, the main shaft 43 is driven to rotate by the motor 42, and the crushing knife 44 is driven to rotate by the main shaft 43. The crushing knife 44 crushes the material in the feed pipe 5, so that the material is dispersed into the upper body 2, effectively preventing the material from agglomerating and affecting the screening efficiency.

[0034] A bulk material plate 45 is provided on the part of the main shaft 43 located in the upper body 2. The bulk material plate 45 is conical. A baffle 14 is provided at a position corresponding to the bulk material plate 45 in the upper body 2. Figure 3 , Figure 4 As shown, the main shaft 43 drives the bulk plate 45 to rotate, and the material in the feed pipe 5 falls onto the bulk plate 45. The conical bulk plate 45 is used to scatter the material entering the upper body 2 in a circumferential direction, so that the material enters the upper body 2 evenly. When the bulk plate 45 scatters the material, the baffle 14 cooperates with the upper body 2 to limit the material on the bulk plate 45, so that the material on the bulk plate 45 is scattered at a certain position in the upper body 2, so as to avoid the material moving too far in the upper body 2 to affect the screening of the material, and the collision of the material with the upper body 2 and the baffle 14 can make the material better dispersed to avoid material agglomeration.

[0035] An observation window 9 is provided on the side of the upper body 2, and a transparent plate 10 is installed in the observation window 9. Figure 6 , Figure 7 As shown, during the working process, the interior of the upper body 2 can be observed through the observation window 9 and the transparent plate 10, so that the material screening process can be understood in time.

[0036] The end of the cross beam 33 at the middle position of the guide rod 32 is equipped with a scraper 11, and the scraper 11 is slidably connected to the transparent plate 10. Figure 3 , Figure 6 As shown, during the working process, some materials will accumulate on the transparent plate 10, causing obstruction to the transparent plate 10. The scraper 11 is driven to move by the crossbeam 33, and the transparent plate 10 is cleaned by the scraper 11, thereby ensuring the cleanliness of the transparent plate 10 and avoiding the use of the transparent plate 10 being affected by the accumulation of materials.

[0037] Working principle: Figure 3-Figure 5 , Figure 7 , Figure 8 As shown, the external conveying device conveys the material into the lower body 1 and the upper body 2 through the feed pipe 5, and the material falls onto the filter assembly 13;

[0038] When the material passes through the feed pipe 5, Figure 3 , Figure 4 As shown, the main shaft 43 is driven to rotate by the motor 42, and the crushing knife 44 and the bulk plate 45 are driven to rotate by the main shaft 43, and the crushing knife 44 is used to crush the material in the feed pipe 5; the material in the feed pipe 5 falls onto the bulk plate 45, and the bulk plate 45 is used to bulk the material, so that the material is dispersed and falls on the filter assembly 13;

[0039] like Figure 7 As shown, after the material falls onto the filter assembly 13, the lower body 1 and the upper body 2 are vibrated by the vibration assembly 6, so that the material on the filter assembly 13 is vibrated, thereby screening the material through the filter assembly 13; during the screening process of the material on the filter assembly 13, as shown in FIG. Figure 3-Figure 5 , Figure 7 , Figure 8 As shown, fine particles in the material are air-selected by the air extraction component 7 and extracted by the air extraction component 7;

[0040] At the same time, if Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, the guide rod 32 is driven by the hydraulic cylinder 31 to move in the lower body 1, and the crossbeam 33 is driven by the guide rod 32 to move in the lower body 1, as shown in FIG. Figure 2 , Figure 6 As shown, the friction between the lower body 1 and the cross beam 33 is reduced by the ball 12, so that the cross beam 33 can move better along the lower body 1;

[0041] like Figure 1-Figure 3 , Figure 5 As shown, the upper support rod 34, the lower support rod 37 and the guide plate 36 are driven by the crossbeam 33 to reciprocate on the filter assembly 13. During the movement, the guide plate 36 turns up the material on the filter assembly 13, so that small particles in the material can be better screened out by the suction assembly 7;

[0042] At the same time, if Figure 1-Figure 3 , Figure 5As shown, since the lengths of the upper support rod 34 and the lower support rod 37 are different, when the upper support rod 34 and the lower surface of the filter assembly 13 and the lower support rod 37 and the upper surface of the filter assembly 13 are in contact, the filter assembly 13 is deformed to different degrees by the upper support rod 34 and the lower support rod 37. Since the filter assembly 13 itself has a certain elasticity, the filter assembly 13 can automatically recover after being deformed by force. Through the deformation and recovery of the filter assembly 13 to different degrees, the material in the filter hole of the filter assembly 13 can be better removed, and the filter hole of the filter assembly 13 can be effectively prevented from being blocked by the material.

[0043] like Figure 6 , Figure 7 As shown, during operation, the interior of the upper body 2 can be easily observed through the observation window 9 and the transparent plate 10; Figure 3 , Figure 6 As shown, the scraper 11 is driven to move by the cross beam 33, and the transparent plate 10 is cleaned by the scraper 11 to avoid affecting the use of the transparent plate 10 due to material accumulation.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
