Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of vibrating screen, in particular to a vibrating screen feeder and a feeding system. BACKGROUND
[0002] The vibrating screen produces vibration through a vibrating motor or other vibration devices, so that the material on the screen surface is subjected to vertical and horizontal forces. Under the combined action of these forces, the material makes a throwing motion on the screen surface, and smaller particles can fall through the screen holes, while larger particles continue to move forward along the screen surface, thereby achieving the purpose of screening different particle size materials.
[0003] At present, the feeding box of the traditional multi-screen channel high-frequency vibrating screen does not have a side material distribution pipeline, that is, it only has a single channel conveying. Meanwhile, the feeding box mainly has two structures. One of them is in the form of an upper material receiving main pipe and a lower two-pipe material distribution. This two-pipe material distribution form cannot meet the requirement of uniform material distribution of the feeding nozzle, resulting in uneven distribution of the mineral material supplied to each screen channel, thereby causing different screen channel pressures and easily causing screen channel blockage. The other structure is that an external material receiving main pipe is connected to a material pipe in the feeding box through two short pipes. The material pipe is in the form of corresponding number of openings according to the number of feeding nozzles (corresponding to the number of screen channels). Due to the uneven pressure at each opening of the material pipe, the mineral material supplied to each screen channel is still uneven, and foreign matter is easily blocked at the opening of the material pipe, which is difficult to clean once blocked. The above two forms of feeding boxes cannot solve the problems of uniform material distribution, improved production and screening efficiency. Moreover, the second feeding box also has the defects of easy blockage, high operation and maintenance cost, etc. CONTENT OF THE INVENTION
[0004] One of the technical problems to be solved by the present application is that the existing feeding box cannot guarantee efficient screening of the vibrating screen while avoiding material blockage and uneven material distribution.
[0005] To solve the above technical problems, the present application provides a vibrating screen feeder, which comprises:
[0006] A feeding box is provided with a feeding tank at the top, and a communication pipe is arranged in the feeding box. The top end of the communication pipe penetrates the feeding box and communicates with the feeding tank. A plurality of side material distribution pipes are arranged on both sides of the communication pipe, and the side material distribution pipes extend to the side wall of the feeding tank. A discharge port is arranged on the side material distribution pipe. A plurality of feeding nozzles are arranged at the bottom of the feeding box, and the position and number of the feeding nozzles correspond to the position and number of the discharge ports.
[0007] In some embodiments, the aforementioned vibrating screen feeder, wherein the feeding box comprises: a feeding box body, a feeding pipe in communication with the feeding box body for receiving external material, and a support plate located outside the feeding box body and covering the top of the feeding box for supporting the feeding box body.
[0008] In some embodiments, the aforementioned vibrating screen feeder, wherein the width of the feeding box is less than the width of the feeding tank.
[0009] In some embodiments, the aforementioned vibrating screen feeder, wherein when the side distribution pipes are two, four or six, the side distribution pipes on the same side are arranged at intervals along the side wall of the communication pipe, and the lengths of the distribution pipes increase in turn.
[0010] In some embodiments, the aforementioned vibrating screen feeder, wherein the bottom of the communication pipe is provided with a middle distribution pipe extending vertically downward.
[0011] In some embodiments, the aforementioned vibrating screen feeder, wherein the diameter of the middle distribution pipe is the same as that of the side distribution pipe.
[0012] In some embodiments, the aforementioned vibrating screen feeder, wherein the inside of the feeding tank is provided with a plurality of distribution plates located between any two adjacent discharge ports to divide the inside of the feeding tank into separate areas.
[0013] In some embodiments, the aforementioned vibrating screen feeder, wherein the opening direction of the discharge port is vertically downward.
[0014] The second aspect of the present application provides a vibrating screen feeding system comprising the aforementioned vibrating screen feeder.
[0015] Through the above technical solution, the vibrating screen feeder provided by the present application can ensure stable material conveying through the feeding box, pre-buffer the material, prevent excessive material from being conveyed to the inside of the feeding tank at one time, causing material blockage in the feeding tank and affecting material conveying, and efficiently comb the material conveyed to the inside of the feeding tank through the communication pipe and the side distribution pipe. When combing, the material in the communication pipe will be smoothly conveyed under the action of the side distribution pipe, and the material in the side distribution pipe will be discharged from the discharge port. Finally, the material is batch-conveyed to the vibrating screen under the action of the feeding nozzle. The discharge port and the feeding nozzle are correspondingly arranged, which can achieve uniform distribution of the material when conveyed to the vibrating screen, and avoid the situation that the material is concentrated in individual areas, affecting the screening effect. Therefore, the feeding tank can not only ensure smooth material conveying without blockage, but also efficiently screen the material when the vibrating screen collects the material.
[0016] On the other hand, the number of side distribution pipes can be adjusted according to the volume of the material actually processed to realize the processing of different types of materials, and the center distribution pipe can also be arranged to reduce the distribution pressure of the side distribution pipes to realize the stable conveying of the material.

[0031] Embodiment one
[0032] Reference is made to the accompanying drawings Figure 1 and the accompanying drawings Figure 4The embodiment discloses a vibrating screen feeder which comprises a feeding box 1, a feeding box 2 is arranged at the top of the feeding box 1, a communication pipe 3 is arranged in the feeding box 1, the top end of the communication pipe 3 penetrates through the feeding box 1 and communicates with the feeding box 2, a plurality of side distribution pipes 4 are arranged at the two sides of the communication pipe 3 and extend to the side walls of the feeding box 2 respectively, a discharge port 5 is arranged on the side distribution pipe 4, and a plurality of feeding nozzles 6 are arranged at the bottom of the feeding box 1 and correspond to the positions and quantities of the discharge ports 5.
[0033] Specifically, in order to solve the problems that the existing feeding box 1 cannot guarantee efficient screening of the vibrating screen, material blockage and uneven distribution of the material, the vibrating screen feeder provided by the embodiment can guarantee efficient conveying of the material and avoid material blockage.
[0034] The feeding box 2 is used for conveying and buffering the material, the volume of the material conveyed to the inside of the feeding box 2 at a time is controlled, and the material is dispersed and distributed through the plurality of side distribution pipes 4 when finally distributed, so that the blockage of the material during conveying is reduced, and the pressure of the material distributed by the single side distribution pipe 4 is reduced due to the distribution of the side distribution pipes 4 on the two sides, so that the vibrating screen feeding box 1 can guarantee efficient conveying of the material and avoid material blockage.
[0035] The vibrating screen feeding box 1 provided by the embodiment is mainly applied to the processing of granular materials, the feeding box 1 is used for temporarily collecting the material, and the size of the feeding box 1 can be adjusted according to actual production needs during design. It can be understood that the top of the feeding box 1 is also provided with the feeding box 2 in order to reduce the pressure of the material stored in the feeding box 1. During processing, the feeding box 2 can first receive the material, and then the feeding box 2 conveys the material to the inside of the feeding box 1 through the communication pipe 3. The feeding box 2 is a hard hollow box, and the width of the feeding box 2 is smaller than that of the feeding box 1. It can be understood that the size of the material received by the feeding box 2 at a time is much smaller than that of the feeding box 1, so that even if the inside of the feeding box 2 is full of material, the blockage of the communication pipe 3 in the feeding box 1 will not be caused when the material is conveyed to the inside of the feeding box 1, so that the smooth transportation and screening of the material are guaranteed. The material is batch-conveyed through the side distribution pipes 4 after entering the communication pipe 3. The plurality of side distribution pipes 4 can greatly improve the conveying efficiency of the material and will not cause the stop of the conveying of the material due to the blockage of the single side distribution pipe 4. Finally, the material is discharged from the discharge port 5 through the side distribution pipe 4 and is conveyed from the feeding nozzle 6. It can be understood that the opening direction of the discharge port 5 is vertically downward, so that the material can be prevented from splashing everywhere during discharging, and the pollution of the material to all areas in the feeding box 1 is effectively reduced.
[0036] Meanwhile, the inside of the feeding tank 1 is provided with a plurality of distribution plates 8, the distribution plates 8 are located between any two adjacent discharge ports 5, so as to divide the inside of the feeding tank 1 into separate areas, specifically, each area corresponds to a discharge port 5 and a feeding nozzle 6 under the action of the distribution plate 8, so that the materials discharged from the adjacent side distribution pipes 4 cannot mix with the materials discharged from the feeding nozzle 6, thereby greatly increasing the output pressure of the feeding nozzle 6, and if the volume of the material is too large, it will also cause blockage, meanwhile, the height of the distribution plate 8 has a certain height, close to the discharge port 5, reducing the possibility of deviation during material conveying, and the distribution plate 8 is connected with the inner wall of the feeding tank 1 to realize complete blockage, the material can only be vertically conveyed downward, meanwhile, each area isolated by the distribution plate 8 can also be provided with a guide plate and a baffle, wherein the guide plate is inclined to guide the material to the specified position, i.e. the position of the feeding nozzle 6, so that the material can be smoothly discharged, and the baffle rotatingly arranged at the feeding nozzle 6 can control the discharge of the material.
[0037] The term "and / or", only describes the association relationship of the associated objects, indicates that there can be three kinds of relationships, for example, A and / or B, and can be understood as: A and B can exist at the same time, A can exist alone, B can exist alone, and any one of the above three cases can exist.
[0038] In some embodiments, reference is made to the accompanying Figure 1 The feeding device provided by the embodiment comprises a feeding tank 1, a feeding tank body 2, a plurality of distribution pipes 4, a plurality of discharge ports 5, a plurality of feeding nozzles 6 and a plurality of communication pipes 3, the feeding tank body 2 is located in the feeding tank 1, the plurality of distribution pipes 4 are located in the feeding tank body 2, the plurality of discharge ports 5 are located in the feeding tank 1 and are connected with the plurality of distribution pipes 4, the plurality of feeding nozzles 6 are located in the feeding tank 1 and are connected with the plurality of communication pipes 3, and the plurality of communication pipes 3 are connected with the plurality of discharge ports 5.
[0039] Specifically, in order to smoothly convey the material, in the embodiment, the feeding tank body 21 is conveyed through the feeding pipe 22, the position of the feeding pipe 22 can be but is not limited to the rear side of the feeding tank body 21, and is inclined to facilitate the conveying of the material, the support plate 23 is a hard metal plate, wherein the hard metal plate is connected with the feeding tank body 21, and the area of the support plate 23 is much larger than that of the feeding tank body 21, so as to ensure that the feeding tank body 21 is stably arranged on the top of the feeding tank 1, thus ensuring the stability of the feeding tank body 21 when conveying a large volume of material, it can be understood that when the material is added, the material is poured into the inside of the feeding tank body 21 through the feeding pipe 22, then conveyed to the inside of the feeding tank 1 through the communication pipe 3, and finally discharged.
[0040] In some embodiments, reference is made to the accompanying Figure 2The vibration sieve feeder provided in the embodiment, in specific implementation, when the middle side distribution pipes 4 are two, or four, or six, the side distribution pipes 4 located on the same side are arranged at intervals along the side wall of the communication pipe 3, and the length of the distribution pipe increases in turn.
[0041] Specifically, in order to ensure that the side distribution pipes 4 do not interfere with each other, in the embodiment, when the side distribution pipes 4 are even, they are evenly distributed on both sides of the communication pipe 3, and according to the size of the communication pipe 3, there are at most six side distribution pipes 4. It can be understood that when the material in the communication pipe 3 is discharged through the side distribution pipes 4, it can be uniformly discharged, so when it is finally discharged from the feeding nozzle 6 on the feeding box 1, it will also uniformly fall onto the surface of the vibration sieve to vibrate. Therefore, when the vibration sieve vibrates, the step of dispersing the blocky material is reduced, thereby accelerating the screening effect. At the same time, the length of the side distribution pipe 4 increases in turn with the distribution of the side distribution pipe 4. It can be understood that when the material is transported through the discharge port 5 on the side distribution pipe 4, the adjacent two discharge ports 5 located on the same side will not cause any influence, and thus the volume of the material discharged from each discharge port 5 is the same, and they will not interfere with each other. Therefore, the volume of the material discharged from the feeding nozzle 6 is also similar, and the feeding nozzle 6 will not be blocked.
[0042] In some embodiments, reference is made to the accompanying Figure 3 The vibration sieve feeder provided in the embodiment, in specific implementation, the bottom of the communication pipe 3 is provided with a middle distribution pipe 7, and the middle distribution pipe 7 extends vertically downward.
[0043] Specifically, in order to ensure smooth transportation of the material, the communication pipe 3 in the embodiment includes a main pipe 31 and an auxiliary pipe 32, wherein the main pipe 31 communicates with the side distribution pipe 4, and the auxiliary pipe 32 communicates with the middle distribution pipe 7. It can be understood that when the material in the main pipe 31 is too much and the side distribution pipe 4 cannot discharge it in time, the excess material in the main pipe 31 will be transported to the auxiliary pipe 32 and finally discharged from the middle distribution pipe 7 on the auxiliary pipe 32, thereby ensuring the discharge of the material and avoiding the risk of blockage. At the same time, the diameters of the middle distribution pipe 7 and the side distribution pipe 4 are the same. It can be understood that if the diameter of the middle distribution pipe 7 is too large, the material in the communication pipe 3 will be discharged from the middle distribution pipe 7 first, thereby causing the discharge pressure of the corresponding feeding nozzle 6 to increase, which easily causes the risk of blockage. Therefore, when the diameters are the same, the volume of the material discharged from each distribution pipe is the same, thereby achieving stable transportation of the material.
