Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal transportation technology, and specifically relates to a four-way chute for uniform material distribution. Background Technology
[0002] In the pre-crushing room of the coking plant's coal preparation area, two crushers at both ends of a four-way chute pre-crush single-type coal with higher hardness, or directly through the middle outlet at the bottom of the chute to the next conveyor belt into the single-type coal bunker. The initial design is for both crushers to operate simultaneously. However, when the crushers are needed, the stacker-reclaimer in the coal yard can have an instantaneous flow rate of over 900T / H. The existing four-way chute cannot distribute the material evenly, resulting in uneven operating loads on the crushers when pre-crushing is required. Under too low a load, the production efficiency of a single crusher will be low, and the crusher motor power is 900KW, resulting in a large amount of power consumption loss. Under overload, the crusher will be damaged due to excessive flow rate, causing excessive oil pressure and temperature of the hydraulic coupling in the transmission. If the load exceeds 900T / H, the rotor will immediately jam or even cause impact damage to the motor. Utility Model Content
[0003] The purpose of this invention is to provide a four-way chute for uniform material distribution, which can avoid the impact of uneven material flow distribution on the equipment load of two crushers and the limitation of the conveying capacity of the stacker-reclaimer, thereby improving equipment utilization and reducing power consumption.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is a four-way chute for uniform material distribution, comprising a chute body,
[0005] The chute body is provided with a feed inlet at the top, and a first discharge outlet and a second discharge outlet are provided on the two sides below the chute body, respectively. A third discharge outlet is provided in the middle of the lower part of the chute body.
[0006] The chute body has a first flap and a second flap respectively inclinedly arranged on both sides; the sides of the first flap and the second flap are arranged opposite each other, and the width of the first flap and the second flap is the same; the top of the first flap contacts the end of the inlet above the second outlet, and the bottom of the first flap contacts the chute body between the first outlet and the third outlet; the top of the second flap contacts the end of the inlet above the first outlet, and the bottom of the second flap contacts the chute body between the second outlet and the third outlet.
[0007] A fixed shaft is provided horizontally within the chute body; a first bushing and a second bushing are respectively fitted at both ends of the fixed shaft; the ends of the first bushing and the second bushing that are far apart from each other and both ends of the fixed shaft pass through the chute body, and the first bushing and the second bushing are rotatably connected to the chute body; the first flap and the second flap are respectively fitted on the first bushing and the second bushing.
[0008] Preferably, the two sides of the outer side of the chute body are respectively provided with telescopic devices arranged opposite to each other; the telescopic devices are arranged opposite to each other, and the telescopic ends of the telescopic devices are rotatably connected to connecting rods; the ends of the two connecting rods away from the telescopic devices are respectively fixedly connected to the first bushing and the second bushing on the outer side of the chute body.
[0009] This utility model provides a four-way chute for uniform material distribution, which has the following advantages compared with the prior art:
[0010] (1) The material enters the chute body from the feed inlet. Under the influence of gravity and material flow velocity, it impacts the first flap and the second flap, and then slides down along the first flap and the second flap respectively, and enters the first discharge port and the second discharge port respectively. Through the uniform distribution of the material flow cross section by the first flap and the second flap, the material flow is guided to be evenly distributed in the first discharge port and the second discharge port.
[0011] (2) Through the two telescopic devices, during the extension of the two telescopic devices, the first bushing will rotate clockwise and the second bushing will rotate counterclockwise, thereby rotating the first flap and the second flap to the vertical state. When it is necessary to directly enter the third discharge port, the first flap and the second flap will be rotated to the vertical state and the feed valves on the first discharge port and the second discharge port will be closed, so that the material can pass through the third discharge port and realize the production mode without passing through the crusher.

[0018] The chute body 1 is provided with a feed inlet 11 at the top, a first discharge outlet 12 and a second discharge outlet 13 on the lower sides of the chute body 1 respectively, and a third discharge outlet 14 in the lower middle part of the chute body 1. The bottom of the first discharge outlet 12 and the second discharge outlet 13 are respectively connected to two crushers, and feed valves are installed on the first discharge outlet 12 and the second discharge outlet 13.
[0019] The chute body 1 has a first flap 2 and a second flap 3 symmetrically inclined on both sides, with the first flap 2 and the second flap 3 having different inclination directions. The sides of the first flap 2 and the second flap 3 are arranged opposite each other, and the widths of the first flap 2 and the second flap 3 are the same. The material entering from the feed inlet 11 will fall onto the first flap 2 and the second flap 3 respectively. The top of the first flap 2 is in contact with the end of the feed inlet 11 above the second discharge outlet 13, and the bottom of the first flap 2 is in contact with the chute body 1 between the first discharge outlet 12 and the third discharge outlet 14. The top of the second flap 3... The material enters the chute body 1 from the inlet 11 above the first outlet 12 and is in contact with the bottom of the second flap 3 and the chute body 1 between the second outlet 13 and the third outlet 14. The material impacts the first flap 2 and the second flap 3 due to gravity and the flow velocity, and then slides down along the first flap 2 and the second flap 3 respectively, entering the first outlet 12 and the second outlet 13 respectively. The material flow is evenly distributed in the cross-section of the material flow by the first flap 2 and the second flap 3, thereby guiding the material flow to be evenly distributed in the first outlet 12 and the second outlet 13.

[0021] The first flap 2 and the second flap 3 are respectively sleeved on the first bushing 16 and the second bushing 17. By rotating the first bushing 16 clockwise and the second bushing 17 counterclockwise, the first flap 2 and the second flap 3 can be rotated from the inclined state to the vertical state. When it is necessary to directly enter the third discharge port 14, the first flap 2 and the second flap 3 are rotated to the vertical state, and the feed valves on the first discharge port 12 and the second discharge port 13 are closed, so that the material can pass through the third discharge port 14, realizing the production mode without passing through the crusher.
