Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material conveying, in particular to a material distributing chute. Background Art
[0002] A chute is a feeding device that does not require power and relies on the potential energy of the material itself to convey the material. Generally, a chute is used to connect between a storage and transportation device and a bunker or between devices, so that the material can continuously run along the process line.
[0003] Chutes are widely used in coal enterprises or iron and steel enterprises, playing important roles in conveying materials and reasonably distributing the conveyed materials on mechanical equipment to avoid eccentric loading.
[0004] The forms of chutes mainly include linear, polyline and spiral shapes, etc. The chute connecting a crusher is mostly linear. However, the longitudinal length of a roll crusher is much longer than that of the chute, which makes the material falling through the linear chute enter the roll crusher more concentratedly without being reasonably distributed, thus affecting the production efficiency of the crusher. Content of the Utility Model
[0005] The purpose of the utility model is to provide a material distributing chute to solve the problem that the traditional linear chute has too concentrated material falling, which affects the production efficiency of the crusher, and enables the material to freely fall for normal distribution, so as to maximize the production efficiency of the crusher.
[0006] A material distributing chute of the utility model includes an upper flange, a lower flange and a chute shell. The chute shell includes a quadrangular prism tube and a rectangular tube. The quadrangular prism tube is fixedly connected to the top of the rectangular tube. The upper flange is fixedly connected to the top of the quadrangular prism tube far from the rectangular tube. The lower flange is fixedly connected to the bottom of the rectangular tube far from the quadrangular prism tube. A material distributing plate is fixedly connected inside the chute shell. There are two material distributing plates, and the two material distributing plates are symmetrical. The upper parts of the two material distributing plates are close to each other, and the lower parts of the two material distributing plates are close to each other and then move away from each other.
[0007] Further, the angle between the mutually opposite surfaces of the two material distributing plates and the horizontal line is a, and a≥45°.
[0008] Further, the material distributing plate is arranged at the junction of the quadrangular prism tube and the rectangular tube in the height direction. The length of the material distributing plate above the junction of the quadrangular prism tube and the rectangular tube is two-thirds of the total length of the material distributing plate, and the length of the material distributing plate below the junction of the quadrangular prism tube and the rectangular tube is one-third of the total length of the material distributing plate.
[0009] Further, the upper part of the material distributing plate is trapezoidal, and the trapezoidal upper part of the material distributing plate is welded to the inner wall of the quadrangular prism tube. The lower part of the material distributing plate is rectangular, and the rectangular lower part of the material distributing plate is welded to the inner wall of the rectangular tube.
[0010] Furthermore, an inspection door is also connected to the side wall of the rectangular pipe.
[0011] Furthermore, a lining plate is connected to the inner wall of the chute housing.
[0012] The beneficial effects of the present utility model are as follows: In the chute housing of the present utility model, there are two fixed connection distributing plates, which are symmetrically arranged. The upper parts of the two distributing plates are close to each other, and the lower parts of the two distributing plates are close to each other and then move away from each other. When the material passes through the distributing plates, a part of the material vertically falls between the two distributing plates, and the other part of the material slides down to both sides of the chute after being blocked by the distributing plates and then enters the crushing process; the arrangement of the distributing plates enables the material to enter downstream equipment such as roll crushers in a manner similar to a normal distribution, improving the crushing efficiency of downstream equipment such as roll crushers, and solving the problem that the material falling through a straight chute in the prior art is relatively concentrated when entering a roll crusher and is not reasonably distributed, thus affecting the production efficiency of the crusher.

[0017] As Figures 1 - 3As shown in the figure, a material distribution chute of the present utility model includes an upper flange 1, a lower flange 2, and a chute housing 3. The chute housing 3 includes a square tube 4 and a rectangular tube 5. The square tube 4 is fixedly connected to the top end of the rectangular tube 5. The upper flange 1 is fixedly connected to the top end of the square tube 4 away from the rectangular tube 5. The lower flange 2 is fixedly connected to the bottom end of the rectangular tube 5 away from the square tube 4. A material distribution plate 7 is fixedly connected inside the chute housing 3. There are two material distribution plates 7, and the two material distribution plates 7 are symmetrical. The upper parts of the two material distribution plates 7 are close to each other, and the lower parts of the two material distribution plates 7 are close to each other and then move away from each other; an inspection door 6 is also connected to the side wall of the rectangular tube 5; the material distribution plate 7 is arranged at the junction of the square tube 4 and the rectangular tube 5 in the height direction. The length of the material distribution plate 7 above the junction of the square tube 4 and the rectangular tube 5 is two-thirds of the total length of the entire material distribution plate 7, and the length of the material distribution plate 7 below the junction of the square tube 4 and the rectangular tube 5 is one-third of the total length of the entire material distribution plate 7; the upper part of the material distribution plate 7 is trapezoidal, and the upper trapezoid of the material distribution plate 7 is welded to the inner wall of the square tube 4. The lower part of the material distribution plate 7 is rectangular, and the lower rectangle of the material distribution plate 7 is welded to the inner wall of the rectangular tube 5.
[0018] The upper flange 1 is connected to upstream equipment such as a belt conveyor, and the lower flange 2 is connected to downstream equipment such as a roll crusher. When the material to be crushed enters the inside of the chute housing 3 from the upper flange 1, the material falls under the action of gravity. When the material passes through the material distribution plate 7, a part of the material falls vertically between the two material distribution plates 7, and the other part of the material slides to both sides of the chute after being blocked by the material distribution plate 7 and then enters the crushing process.
[0019] The setting of the material distribution plate 7 enables the material to enter downstream equipment such as a roll crusher in a manner similar to a normal distribution, improving the crushing efficiency of downstream equipment such as a roll crusher.
[0020] The included angle between the opposite surfaces of the two material distribution plates 7 and the horizontal line is a, and a ≥ 45°.
[0021] The actual inclination angle of the two material distribution plates 7 needs to be determined according to the material characteristics, generally controlled at a ≥ 45°. The cross-sectional size of the cavity formed between the material distribution plate 7 and the inner wall of the chute housing 3 needs to be determined according to factors such as the particle size of the material, and it is sufficient to ensure that the material can pass smoothly.
[0022] The inspection door 6 is usually composed of angle steel, steel plate, and round steel welded together, and is used to check and repair the internal wear of the chute housing 3.
[0023] A lining plate can also be connected to the inner wall of the chute housing 3. The material of the lining plate can be selected according to the characteristics of the material. Commonly used lining plate materials are generally high manganese steel Mn13-4, high molecular polyethylene, high manganese cast steel, high chromium composite alloy, or composite ceramics. The setting of the lining plate extends the service life of the chute housing 3.
