Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building material production preparation technology, and concretely relates to a circular vibrating screen material feeding uniform distribution device. BACKGROUND

[0002] With the gradual attention to environmental protection, the mechanical preparation aggregate sand preparation rises. In the mechanical preparation aggregate machine sand preparation process, the circular vibrating screen is an indispensable key equipment. The circular vibrating screen is a common vibrating screening equipment, mainly used for material classification, screening and impurity removal. The vibrating motor or exciter generates excitation force, so that the screen box moves in a circular or approximately circular trajectory in the vertical plane. The material on the screen surface is thrown and falls, realizing the screening process.

[0003] However, in a large number of production lines in production, the existing circular vibrating screen has the problem of low screening efficiency, which seriously affects the production capacity and seriously restricts the production capacity. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the problem of uneven feeding of the aggregate circular vibrating screen in the prior art, and provides a circular vibrating screen material feeding uniform distribution device. The circular vibrating screen material feeding uniform distribution device has uniform feeding, energy saving and environmental protection, and greatly improves the screening efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a circular vibrating screen material feeding uniform distribution device, which comprises a mixing box fixed above the inlet of the screening machine through a fixing frame. The top of the mixing box is provided with a feeding port, and the bottom of the mixing box is provided with a plurality of discharge ports below the feeding port. The plurality of discharge ports are arranged uniformly along a straight line or arranged uniformly along a circumference with one discharge port as the center. Cubic blocks are arranged at the edges of the discharge ports on the side or around the center. Ladder-shaped three-dimensional blocks are arranged at the edges of the discharge ports at the center. The ladder-shaped three-dimensional blocks extend divergently towards the plurality of cubic blocks.

[0006] Preferably, a plurality of material flow channels are formed between the ladder-shaped three-dimensional blocks and the cubic blocks, and the material flow channels are communicated with the discharge ports.

[0007] Preferably, an expanding port is formed downward from the feeding port on the mixing box.

[0008] Preferably, an extension material channel extending into the inlet of the screening machine is formed on the discharge port.

[0009] Preferably, the extension material channel is ladder-shaped, and the lowest material channel port extends into the inlet of the screening machine.

[0010] Preferably, the mixing box is detachably fixed to the fixing frame.

[0011] Preferably, the cubic baffle and the stepped three-dimensional baffle are detachably fixed to the inside of the mixing tank.

[0012] Preferably, the extension channel is detachably fixed to the bottom of the mixing box.

[0013] Preferably, a reinforcing lip is formed on the edge of the feed inlet in the circumferential direction.

[0014] According to the above technical solution, a fixing frame is used to fix the mixing box above the inlet of the screening machine. The top of the mixing box has a feed inlet, and the bottom has multiple discharge outlets. These outlets are evenly arranged in a straight line, or, with one outlet as the center, the others are evenly arranged around the circumference. Furthermore, cubic baffles are located at the edges of the side or surrounding outlets, and stepped three-dimensional baffles are located at the edges of the central outlet, radiating outwards towards the cubic baffles. Thus, when material enters the mixing box from the feed inlet, it falls under the influence of gravity. Upon encountering the stepped three-dimensional baffle at the center, it overflows in a stepped manner along the outer contour of the baffle and flows outwards. After being slowed and accumulated at the cubic baffles, it leaves the mixing box through the multiple discharge outlets and continues to fall into the screening machine under the influence of gravity. At this point, the automatic material distribution device evenly distributes the material, improving the utilization rate of the screening machine's screen surface, fully utilizing the machine's capacity, and effectively solving the problem of uneven feeding. Simultaneously, this device requires no forced adjustment by any motor, is environmentally friendly and energy-saving, and significantly improves the screening efficiency of the circular vibrating screen.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional terms such as "top," "bottom," "upper," "lower," "center," and "surroundings" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0025] See Figures 1 to 3 This utility model provides a circular vibrating screen feeding uniform distribution device, which includes a mixing box 1 fixed above the inlet of the screening machine 8 by a fixing frame 3. The top of the mixing box 1 is provided with a feeding port 4, and the bottom of the mixing box 1 is provided below the feeding port 4 with multiple discharge ports 2. The multiple discharge ports 2 are evenly arranged along a straight line or with one discharge port 2 as the center and the other discharge ports 2 are evenly arranged along the circumference. Among them, the edges of the discharge ports 2 located on the side or around are provided with cubic blocks 7, and the edges of the discharge ports 2 located in the center are provided with stepped three-dimensional blocks 6. The stepped three-dimensional blocks 6 extend outward toward the multiple cubic blocks 7.

[0026] Through the above technical solution, the mixing box 1 is fixed above the inlet of the screening machine using the fixing frame 3. The top of the mixing box 1 is provided with a feed inlet 4, and the bottom of the mixing box 1 is provided with multiple discharge outlets 2. The multiple discharge outlets 2 are evenly arranged in a straight line, or with one discharge outlet 2 as the center and the other discharge outlets 2 are evenly arranged in a circle. Furthermore, the edges of the discharge outlets 2 located on the sides or around the perimeter are provided with cubic baffles 7, and the edges of the discharge outlets 2 located in the center are provided with stepped three-dimensional baffles 6. The stepped three-dimensional baffles 6 extend outwards towards the multiple cubic baffles 7. In this way, when the material enters the mixing box 1 from the feed inlet 4, it falls under the influence of gravity. After encountering the stepped three-dimensional baffles 6 located in the center, it overflows in a stepped manner along the outer contour of the stepped three-dimensional baffles 6 and flows to the surrounding areas. After encountering the cubic baffles 7, it slows down and accumulates before leaving the mixing box 1 from the multiple discharge outlets 2 and continues to fall into the screening machine under the influence of gravity. At this point, the automatic material distribution device evenly distributes the material, improving the utilization rate of the screening machine's screen surface, fully utilizing the machine's capacity, and effectively solving the problem of uneven feeding. Simultaneously, this device requires no forced adjustment by any motor, is environmentally friendly and energy-saving, and significantly improves the screening efficiency of the circular vibrating screen.

[0027] In this embodiment, to ensure that the material falling under the influence of gravity can smoothly overflow and flow outwards after encountering the stepped three-dimensional baffle 6 located at the center, preferably, multiple material flow channels are formed between the stepped three-dimensional baffle 6 and the cubic baffle 7, and the material flow channels are connected to the discharge port 2. In this way, the material can smoothly reach the discharge port 2 at other locations and flow out from the discharge port 2 by following the multiple material flow channels and being guided by the multiple material flow channels.

[0028] In this embodiment, in order to increase the volume of the mixing tank 1 so that it can provide enough space for a large amount of material to be evenly distributed, and at the same time avoid the material from directly impacting the device housing, a wear-resistant measure of "material grinding material" is adopted to extend the service life of the device. Preferably, an flared opening 5 is formed on the mixing tank 1 from the feed inlet 4 downwards.

[0029] In this embodiment, in order to ensure that the material flowing out of the discharge port 2 can accurately enter the screening machine 8, improve the material collection rate, and avoid unnecessary material waste during production and processing, it is preferable to form an extended material channel on the discharge port 2 that extends into the inlet of the screening machine 8. In this way, the material flowing out of the discharge port 2 will not be randomly thrown or splashed, but will enter the inlet of the screening machine 8 in an orderly manner along the extended material channel, which is efficient and reliable.

[0030] In the process of guiding materials using the aforementioned extended material channel, in order to prevent the material from passing through too quickly and making it difficult to control the flow rate, and to ensure that the material in the multiple discharge ports 2 can be discharged evenly, preferably, the aforementioned extended material channel is stepped, with the lowest point of the channel extending into the inlet of the screening machine 8. After adopting the stepped extended material channel, the material will change in multiple directions when passing through the extended material channel, instead of being discharged instantaneously, in large quantities, and at high speed from the discharge ports 2, thus achieving uniform, uniform speed, and stable discharge.

[0031] In addition, in order to facilitate the installation and disassembly of the feed distribution device of the circular vibrating screen, as well as to maintain it during use and extend its service life, it is preferable to detachably fix the mixing box 1 to the fixed frame 3.

[0032] Similarly, in order to select appropriate baffles according to materials with different properties and to facilitate the adjustment of the specific position of the baffles according to the uniform distribution design, it is preferable to detachably fix the cubic baffles 7 and the stepped three-dimensional baffles 6 to the inside of the mixing box 1.

[0033] In addition, different materials have different flow rates, so the specific structure of the extended material channel required is also different. In order to quickly and conveniently install or disassemble and replace the extended material channel with different specific structures according to specific usage requirements, preferably, the extended material channel is detachably fixed to the bottom of the mixing box 1.

[0034] The above-mentioned detachable connection method can be any mechanical connection structure commonly found in the field that can achieve quick installation and disassembly. However, from the perspective of simplifying operation, controlling costs, and facilitating material sourcing, the above-mentioned detachable connection method is to connect by means of bolts and nuts.

[0035] In this embodiment, to extend the service life of the circular vibrating screen feed distribution device, it is often made of iron or steel plates. However, to control the overall weight of the device, thinner iron or steel plates are used. In actual use, the feed inlet often connects with the discharge inlet of belt conveyors, vibrating feeders, etc. When adjustments are made at the connection point, they are prone to colliding, causing deformation of the feed inlet 4. This reduces the feeding area at the feed inlet 4, lowers working efficiency, and can even lead to serious issues like material leakage and spillage. Therefore, to avoid these problems, a reinforcing lip plate is preferably formed along the circumferential direction on the edge of the feed inlet 4. This reinforcing lip plate enhances the mechanical strength of the circumferential direction of the edge of the feed inlet 4, preventing easy deformation and maintaining its original good mechanical structure. In one specific embodiment, the aforementioned reinforcing lip plate can be obtained by flanging the edge of the feed inlet 4. This not only enhances strength but also prevents the harder, sharper feed inlet 4 from cutting the operator's hands or scratching other mechanical parts, achieving two benefits at once. Furthermore, the discharge outlet 2 maintains a gap of at least 100mm with the screen of the screening machine to prevent contact between the equipment and this device during operation.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
