Description

Technical fields:

[0001] This utility model relates to the field of machinery, specifically to a raw material conveying system. Background technology:

[0002] The production of calcium carbide uses multiple lime kilns and vertical drying kilns for carbon materials. During the material transport process via belt conveyors, especially when feeding or discharging materials from the kiln to the next stage, there are situations where the material drop is large. Specifically, the material is discharged onto the belt conveyor through a flap three-way valve and a chute. The long-term vertical impact of the material can easily cause severe wear and tear on the flap three-way valve, chute, and belt, resulting in a high breakage rate. In addition, there are cases where the material is discharged from the kiln in a burning state. Damage to the flap three-way valve and chute can easily lead to material leakage and cause fires. Utility Model Content:

[0003] The purpose of this invention is to provide a raw material conveying system.

[0004] This utility model is implemented by the following technical solution:

[0005] A raw material conveying system includes a boat-type three-way distributor, an arc-shaped chute, a belt conveyor, and a buffer bed. The two distributing outlets of the boat-type three-way distributor are respectively connected to one end of the arc-shaped chute, and the other end of the arc-shaped chute is connected to the inlet of the belt conveyor.

[0006] The boat-shaped chute of the boat-type tee distributor is provided with a U-shaped inner lining slide. The inner wall of the material outlet of the boat-type tee distributor housing is fitted with an inner lining plate. Multiple inserts are fixed at the bottom of the inner lining slide and on one side of the inner lining plate. The bottom of the boat-shaped chute and the inner wall of the material outlet of the housing are provided with through holes for inserting the inserts. Multiple baffles are provided below the boat-shaped chute and on the outside of the housing of the boat-type tee distributor. The baffles correspond to the through holes and are screwed to the inserts in the through holes by bolts.

[0007] The buffer bed is fixed at the bottom of the belt below the inlet of the conveyor belt.

[0008] Preferably, the inner lining slide includes a U-shaped bottom lining plate and two semi-circular side plates on both sides. The bottom of the two semi-circular side plates are symmetrically provided with grooves. The semi-circular side plates are fitted onto the side ends of the bottom lining plate through the grooves and are fixedly connected by bolts.

[0009] The advantages of this utility model are: when raw materials enter the boat-type three-way distributor, they come into contact with the wear-resistant inner lining slide and inner lining plate, which slows down wear, reduces the breakage rate, and improves the situation of easy material leakage causing fire. The inner lining slide and inner lining plate can be replaced by simply removing some bolts, unlocking the baffle, and pulling out the through hole through the insert block. The reverse installation is also convenient.

[0010] The raw materials pass through the arc-shaped chute. The arc-shaped chute extends the arc-shaped passage surface, improving the drop. This not only extends the contact surface of the raw materials, avoiding excessive local impact, but also allows the raw materials to roll quickly, reducing bouncing and achieving the effect of stress relief, thus extending the service life.

[0011] The raw material falls onto the conveyor belt and is cushioned by the buffer bed, thus protecting the conveyor belt. Attached image description:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5As shown, a raw material conveying system includes a boat-type three-way distributor 1, an arc-shaped chute 2, a belt conveyor 3, and a buffer bed 4. The two distributing outlets of the boat-type three-way distributor 1 are respectively connected to one end of the arc-shaped chute 2, and the other end of the arc-shaped chute 2 is connected to the inlet of the belt conveyor 3.

[0021] Raw materials enter the boat-type three-way distributor 1, and are discharged from any of the distribution outlets to different arc-shaped chutes 2, and then fed into the corresponding belt conveyor 3 to feed the kiln, or transported to the next stage of feeding.

[0022] The boat-shaped chute 1.1 of the boat-shaped tee distributor 1 is provided with a U-shaped inner lining slide 5. The inner wall of the material outlet of the shell 1.2 of the boat-shaped tee distributor 1 is fitted with an inner lining plate 6. Multiple inserts 7 are fixed at the bottom of the inner lining slide 5 and on one side of the inner lining plate 6. The bottom of the boat-shaped chute 1.1 and the inner wall of the material outlet of the shell 1.2 are provided with through holes 8 for inserting the inserts 7. Multiple baffles 9 are provided below the boat-shaped chute 1.1 and on the outside of the shell 1.2 of the boat-shaped tee distributor 1. The baffles 9 correspond to the through holes 8 and are screwed to the inserts 7 in the through holes 8 by bolts.

[0023] Raw materials fall into the boat-shaped chute 1.1 of the boat-shaped three-way distributor 1. The chute 1.1 is usually rotated to redirect the material to two different outlets. The material first contacts the inner lining slide 5 inside the boat-shaped chute 1.1, including the bottom and sides. The inner lining slide 5 is made of commonly used wear-resistant materials in the industry, such as ceramics or alloy plates. The inner lining slide 5 can withstand long-term impact from the raw materials. When it needs to be replaced due to wear, only some bolts need to be removed (two in this embodiment), the baffle 9 needs to be unlocked, and the inner lining slide 5 can be pulled out through the through hole 8 via the insert 7 and removed. Conversely, installation is also convenient: the insert 7 is inserted into the through hole 8 for positioning, and the baffle 9 is screwed in to secure the inner lining slide 5 and prevent it from detaching from the boat-shaped chute 1.1. When the raw materials exit from different outlets, they will also impact the inner wall of the housing 1.2 at the outlet. At this time, the inner lining plate 6 is contacted first. It is also made of commonly used wear-resistant materials in the industry. When it needs to be replaced due to wear, the operation is the same as the disassembly of the inner lining slide 5, making it convenient to use.

[0024] The arc-shaped chute 2 comes in various forms, such as... Figure 1 The shape shown is an arc, as... Figure 4 As shown, it is twisted in a circumferential direction, or as... Figure 5 The shape shown is slightly spiral, but its form is not limited to that shown in this embodiment. Its essence is to improve the drop by lengthening the arc-shaped passage surface. This not only extends the contact surface of the material sliding down and avoids excessive local impact, but also allows the material to roll quickly, reducing bouncing, achieving the effect of stress relief and extending service life.

[0025] The bottom of the belt conveyor 3, located below the inlet, is fixed with a buffer bed 4. The raw materials falling into the belt conveyor 3 are buffered by the buffer bed 4, protecting the belt.

[0026] The inner lining slide 5 includes a U-shaped bottom lining plate 5.1 and two semi-circular side plates 5.2 on both sides. The bottom of the two semi-circular side plates 5.2 are symmetrically provided with grooves 5.3. The semi-circular side plates 5.2 are fitted onto the side ends of the bottom lining plate 5.1 through the grooves 5.3 and are fixedly connected by bolts.

[0027] If either the bottom liner 5.1 or the semi-circular side plate 5.2 is damaged, it can be replaced locally by disassembling and assembling with bolts.

[0028] Working principle: When using this utility model, the raw material enters the boat-shaped three-way distributor 1, first contacting the inner lining slide 5 inside the boat-shaped chute 1.1, and then colliding with the inner lining plate 6 on the inner wall of the distribution outlet. The inner lining slide 5 and inner lining plate 6 are made of wear-resistant materials commonly used in the industry. When wear is required for replacement, it is only necessary to remove some bolts, unlock the baffle 9, and pull out the through hole 8 through the insert block 7 to remove it. Conversely, installation is also convenient. The insert block 7 is inserted into the through hole 8 for positioning, and the baffle 9 is screwed on to lock the inner lining slide 5 or inner lining plate 6 to disengage. The raw material is discharged from any distribution outlet to different arc-shaped chute 2. After the impact is further reduced in the arc-shaped chute 2, it enters the corresponding belt conveyor 3, is buffered by the buffer bed 4, and the belt is protected. Then, the belt conveyor 3 feeds the material to the kiln or transports it to the next stage of feeding.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
