Description

Technical Field

[0001] The utility model belongs to the technical field of silo gates, and in particular relates to a wear-resistant gate structure used for silos. Background Art

[0002] In the industrial production process, the normal operation of various equipment is crucial to production efficiency and working environment hygiene. Especially in the fields of mineral processing, building materials production, metallurgy, etc., a large amount of bulk material transportation is involved. Among them, the gate is an important material control equipment, and its performance directly affects the stability and safety of the production process.

[0003] In the traditional gate design, when the silo is discharged, the inner wall lining of the gate directly contacts and bears the impact and friction of a large amount of bulk materials, resulting in severe wear of the inner wall, and the gate plate of the gate will also be constantly worn during the frequent opening and closing process. As the use time increases, the gate may be worn out, causing material leakage, which not only affects the production progress, but also may cause problems with the working environment and deteriorate the working environment of employees. At the same time, frequent maintenance and plugging work will also increase the labor intensity of employees. More importantly, during the continued use of maintenance equipment, wear will be further aggravated, increasing the possibility of equipment breakage or detachment, which may cause major safety accidents, cause harm to personnel and facilities, and bring serious economic losses.

[0004] Therefore, a wear-resistant gate structure for a silo with high wear resistance and durability is now needed. Utility Model Content

[0005] The purpose of the utility model is to provide a wear-resistant gate structure for a silo, which has high wear resistance and durability, can effectively extend the service life of the gate, improve production line efficiency, and save economic costs.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A wear-resistant gate structure for a silo, comprising a gate body with a flange on the top, a guide frame horizontally mounted on the outside of the gate body, a driving device arranged at one end of the guide frame and controlled by a control mechanism, and a gate plate movably arranged at the other end of the guide frame and connected to the driving device, the gate body being a box structure that penetrates from top to bottom, and a side wall close to the gate plate is inclined and has a through hole adapted to the gate plate; a plurality of wear-resistant structures are evenly spaced above the inner wall of the gate body along its height direction, the wear-resistant structure comprising a horizontally arranged material storage lining plate, wherein a first material storage lining plate is provided with a ceramic lining plate that is flush with the flange.

[0008] A further improvement of the technical solution of the utility model is that at least five material storage lining plates are provided, and the width of each material storage lining plate decreases from top to bottom.

[0009] A further improvement of the technical solution of the utility model is that: the width of the first material storage lining plate is L, the maximum diameter of the gate body is D, and 1 / 7D≥L≥1 / 10D.

[0010] The further improvement of the technical solution of the utility model is that: the material storage lining plate includes four wear-resistant strips which are horizontally arranged on the inner wall of the gate body in the circumferential direction and connected end to end; the interval between each material storage lining plate is 90-110mm.

[0011] A further improvement of the technical solution of the utility model is that the driving device includes hydraulic cylinders respectively arranged on the outer walls of the guide rods on both sides of the guide frame, and a through slide groove is correspondingly opened at one end of the two guide rods away from the hydraulic cylinder. The gate plate is arranged between the two guide rods and connected to the hydraulic cylinder through a connecting rod passing through the slide groove.

[0012] A further improvement of the technical solution of the utility model is that a ceramic lining plate 2 is arranged at one end of the gate plate close to the gate body.

[0013] The further improvement of the technical solution of the utility model is that the wear-resistant strips of the material storage lining plate are made of manganese-iron alloy; and the interval between each material storage lining plate is 100 mm.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0015] The wear-resistant gate structure of the utility model for the silo has high wear resistance and durability, can effectively prolong the service life of the gate, improve the efficiency of the production line, and save economic costs.

[0016] The utility model adopts a gate body, a guide frame, a driving device and a gate plate that cooperate with each other. The control mechanism can control the driving device to drive the gate plate to move horizontally on the guide frame relative to the gate body. During the horizontal movement, the gate plate can be opened through the through hole on the inclined side wall of the gate body or the gate body, which can effectively control the material passing through the gate body.

[0017] The utility model adopts a method of evenly arranging a plurality of wear-resistant structures above the inner wall of the gate body along its height direction. The wear-resistant structures are horizontally arranged material storage liners. The gaps between the various material storage liners can retain a portion of the material, so that the material passing through the gate body directly rubs against the material on the material storage liners, thereby avoiding the material passing through the gate body rubbing against the inner wall of the gate body, thereby effectively extending the service life of the gate.

[0018] The utility model adopts a ceramic lining plate which is flush with the flange on the first material storage lining plate, thereby being able to effectively increase the wear resistance of the first material storage lining plate. This is because the first material storage lining plate is subject to the most severe wear, so such a setting is more conducive to extending the service life of the entire gate.

[0019] The width of each material storage lining plate adopted by the utility model decreases from top to bottom, which can prevent the material passing through the gate body from directly rubbing against the inner wall of the gate body and can also prevent the material from passing poorly due to excessive reduction in diameter.

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] like Figure 1 As shown, the utility model provides a wear-resistant gate structure for a silo, including a gate body 1, a guide frame 2, a driving device and a gate plate 3 that cooperate with each other. The gate body 1 is a box structure that is through from top to bottom. A flange 11 is sleeved on the top of the gate body 1. The guide frame 2 is sleeved horizontally on the outside of the gate body 1 and fixedly connected to the outer wall of the gate body 1. The driving device is arranged at one end of the guide frame 2 and is controlled by a control mechanism. The control mechanism can use a motor arranged on the guide frame 2. The gate plate 3 is arranged at the other end of the guide frame 2 and is connected to the driving device. The side wall of the gate body 1 close to the gate plate 3 is inclined and is provided with a through hole 12 adapted to the gate plate 3. Under the control of the control mechanism, the driving device can drive the gate plate 3 to move horizontally relative to the gate body 1 on the guide frame 2. During the horizontal movement, the gate plate 3 can pass through the through hole 12 on the inclined side wall of the gate body 1, thereby opening or closing the gate body 1 to control the passage of materials.

[0024] A plurality of wear-resistant structures are evenly spaced above the inner wall of the gate body 1 along its height direction. Specifically, the wear-resistant structure is a material storage lining plate 13 horizontally arranged on the inner wall of the gate body 1. The gaps between the material storage lining plates 13 can retain a portion of the material, so that the material passing through the gate body 1 and the material on the material storage lining plate 13 are rubbed, thereby preventing the material passing through the gate body 1 from directly rubbing against the inner wall of the gate body 1, that is, the original lining plate on the inner wall, thereby effectively extending the service life of the gate.

[0025] Since the first storage lining 13 is the most severely worn, the interval between the first storage lining 13 and the flange 11 is set to 25 mm, so that a ceramic lining 14 flush with the flange 11 can be set on the first storage lining 13. The ceramic lining 14 can be connected to the storage lining 13 by bonding, which can effectively increase the wear resistance of the first storage lining 13. At the same time, since the gate plate 3 collides with the inner wall of the gate body 1 during the continuous opening and closing process, it is also prone to wear. Therefore, a ceramic lining 2 31 is set by bonding at one end of the gate plate 3 close to the gate body 1 to improve the wear resistance of the end of the gate plate 3. Such a setting can further extend the service life of the entire gate.

[0026] The width of the material storage liner 13 can be selected according to the diameter of the gate body 1. The width of each material storage liner 13 can be the same, but it is more preferable that the width of each material storage liner 13 decreases from top to bottom. This can prevent the material passing through the gate body 1 from directly rubbing against the inner wall of the gate body 1, and can also prevent the material from passing through the gate body 1 too smoothly due to excessive shrinkage. The width of the first material storage liner 13 is L, and the maximum diameter of the gate body 1 is D. 1 / 7D≥L≥1 / 10D, and the preferred L=1 / 8D.

[0027] Specifically, the material storage lining 13 is composed of 4 wear-resistant strips of manganese-iron alloy, which have the characteristics of high rigidity and strong wear resistance. The 4 wear-resistant strips are horizontally arranged along the circumference of the inner wall of the gate body 1 and welded to each other end to end in a "U" shape. The interval between each material storage lining 13 is 90-110mm. Preferably, the interval between each material storage lining 13 is 100mm, which is more convenient for material storage.

[0028] The number of the material storage lining plates 13 can be designed according to the height of the gate body 1 . Preferably, at least five material storage lining plates 13 are provided.

[0029] The driving device includes hydraulic cylinders 4 respectively arranged on the outer walls of the guide rods on both sides of the guide frame 2. The two hydraulic cylinders 4 are controlled by a motor to retract and extend together. A through slide groove 21 is correspondingly opened at one end of the two guide rods away from the hydraulic cylinder 4. The gate plate 3 is arranged between the two guide rods and connected to the hydraulic cylinder 4 through a connecting rod 22 passing through the slide groove 21. The slide groove 21 extends a certain length along the length direction of the guide rod. The length setting of the slide groove 21 needs to take into account the length of the path moved by the gate plate 3 when opening or closing the gate body 1.

[0030] During the material discharging operation, the control mechanism controls the two hydraulic cylinders 4 to extend and drive the gate plate 3 to move horizontally along the guide rods on both sides of the guide frame 2 to open the gate body 1, so that the material in the silo passes through the gate body 1. The material that first passes through the material storage liner 13 is retained on the material storage liner 13. When the subsequent material enters the gate body 1, it directly contacts the material retained on the material storage liner 13, avoiding contact between these materials and the inner wall of the gate body 1, thereby effectively extending the service life of the gate. After all the materials have passed through the gate body 1, the control mechanism controls the two hydraulic cylinders 4 to contract and drive the gate plate 3 to move horizontally along the guide rods on both sides of the guide frame 2 to close the gate body 1, thereby ending the material discharging.
