Description

Technical Field

[0001] This utility model relates to the field of panel door technology, and in particular to a V-shaped panel door and a material feeding mechanism. Background Technology

[0002] Material blockage often occurs during the conveying of solid materials in powder, granular, lumpy or mixed form, especially in the process of conveying raw coal in thermal power plants, where coal sticking, coal bridging and blockage are frequently encountered in the coal hopper. Therefore, it is necessary to cut off the material to facilitate maintenance.

[0003] Currently, baffle gates are commonly used to cut off materials. However, existing baffle gates are usually horizontal straight-through baffle gates. The moisture content of raw coal varies in different regions. When the moisture content of the raw coal being transported is high, water can easily enter the equipment through the baffle gate, causing the equipment to rust and be damaged.

[0004] Therefore, a V-shaped insert gate and a material unloading mechanism are provided to solve the above-mentioned problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a V-shaped insert gate and a material feeding mechanism to solve the problems existing in the prior art. It can prevent water in the material from entering the insert gate and causing damage, and can also prevent material from accumulating.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a V-shaped insert door, including an insert shell, a first insert plate, and a second insert plate. The insert shell can be fixed on a material discharge channel. The first insert plate and the second insert plate are slidably disposed on both sides of the insert shell, and both the first insert plate and the second insert plate are inclined downwards along the direction close to the center of the material discharge channel. The first insert plate is also connected to a first driving mechanism, and the second insert plate is also connected to a second driving mechanism. The first driving mechanism and the second driving mechanism can drive the first insert plate and the second insert plate to move closer to each other or further away from each other. When the first insert plate and the second insert plate move away from each other, the material discharge channel can be opened; when the first insert plate and the second insert plate move closer to each other, the material discharge channel can be closed. The first insert plate and the second insert plate form a V-shaped structure.

[0008] Preferably, the insert plate housing is a V-shaped housing, which includes a first insert plate housing and a second insert plate housing. The first insert plate housing and the second insert plate housing are symmetrically arranged on both sides of the material discharge channel, and both are inclined downwards in a direction close to the center of the material discharge channel; wherein, the first insert plate and the second insert plate are slidably disposed in the first insert plate housing and the second insert plate housing, respectively.

[0010] Preferably, the tilt angle of the first insert plate and the second insert plate is 5° to 30°.

[0011] Preferably, both the first driving mechanism and the second driving mechanism include a cylinder, the cylinder being fixed to the end of the insert plate housing, and the cylinder rod extending into the insert plate housing and connected to the first insert plate or the second insert plate.

[0012] Preferably, the cylinder is fixed to the end of the insert plate housing by a fixing seat, and the fixing seat and the cylinder, as well as the fixing seat and the insert plate housing, are fixedly connected by bolts.

[0013] Preferably, both the first drive mechanism and the second drive mechanism include a plurality of cylinders arranged side by side.

[0014] Preferably, it further includes a limiting mechanism, which is used to limit the movement position of the first insert plate and the second insert plate.

The first and second limiting switches are respectively disposed at the front and rear ends of the cylinder, and the sensing block is located between the first and second limiting switches. When the first or second limiting switch senses the sensing block, the cylinder stops working.

[0016] This utility model also provides a material unloading mechanism, including the V-shaped insert gate as described above.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] The V-shaped insert gate of this utility model includes an insert shell, a first insert plate, and a second insert plate. The insert shell can be fixed on the material discharge channel. The first insert plate and the second insert plate are slidably disposed on both sides of the insert shell, and both the first insert plate and the second insert plate are inclined downwards along the direction close to the center of the material discharge channel. The first insert plate is also connected to a first driving mechanism, and the second insert plate is also connected to a second driving mechanism.

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.

[0026] The purpose of this utility model is to provide a V-shaped insert gate and a material feeding mechanism to solve the problems existing in the prior art. It can prevent water in the material from entering the insert gate and causing damage, and can also prevent material from accumulating.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figures 1-3 As shown, this embodiment provides a V-shaped insert door, mainly including an insert housing 2, a first insert plate 5, and a second insert plate 6. The insert housing 2 can be fixed on the material discharge channel 1. The first insert plate 5 and the second insert plate 6 are respectively slidably disposed on both sides of the insert housing 2, and both the first insert plate 5 and the second insert plate 6 are inclined downwards in a direction close to the center of the material discharge channel 1. The first insert plate 5 is also connected to a first driving mechanism 3, and the second insert plate 6 is also connected to a second driving mechanism 4. The first driving mechanism 3 and the second driving mechanism 4 can drive the first insert plate 5 and the second insert plate 6 to move closer to each other or further away from each other. The material discharge channel 1 has openings on both sides for the first insert plate 5 and the second insert plate 6 to pass through. When the first insert plate 5 and the second insert plate 6 move away from each other, the material discharge channel 1 can be opened. When the first insert plate 5 and the second insert plate 6 move closer to each other, the material discharge channel 1 can be closed. The first insert plate 5 and the second insert plate 6 form a V-shaped structure.

[0030] In this embodiment, both the first insert plate 5 and the second insert plate 6 are inclined downwards along the direction close to the center of the material discharge channel 1, forming a V-shaped structure. When the material being transported has a high water content, the water in the material can move downwards along the inclined insert plates, preventing it from entering the device and causing rust or damage. Moreover, the downward inclination of the first insert plate 5 and the second insert plate 6 facilitates the downward movement of the material when it is opened, preventing material accumulation.

[0031] In this embodiment, it should be noted that the material discharge channel 1 can be selected as needed. It can be a coal hopper for conveying raw coal in a thermal power plant, but it is not limited to a coal hopper. It can also be a material discharge hopper or material discharge pipe for conveying other materials.

[0032] In this embodiment, the insert plate housing 2 is a V-shaped housing, which includes a first insert plate housing and a second insert plate housing. The first insert plate housing and the second insert plate housing are symmetrically arranged on both sides of the material discharge channel 1, and are both inclined downward along the direction close to the center of the material discharge channel 1. The first insert plate housing and the second insert plate housing form the V-shaped housing. The first insert plate 5 and the second insert plate 6 are respectively slidably disposed in the first insert plate housing and the second insert plate housing.

[0033] In this embodiment, it should be noted that the first insert shell and the second insert shell can be an integral structure or a separate structure.

[0034] In this embodiment, the first insert plate 5 and the second insert plate 6 are symmetrically arranged, and their tilt angle is preferably 5° to 30°, for example, 5°, 10°, or 20°. It should be noted that the "tilt angle" is the angle between the insert plate and the horizontal plane. Using the above-mentioned tilt angle in this embodiment avoids situations where a small tilt angle allows moisture to seep in along the gaps between the insert plates, and where material tends to accumulate on the insert plates. It also avoids situations where an excessively large tilt angle causes material to slide down rapidly when the insert plates open, making control difficult. Furthermore, the first insert plate 5 and the second insert plate 6 can be set to different angles as needed to suit different materials.

[0035] In this embodiment, both the first driving mechanism 3 and the second driving mechanism 4 include a cylinder 11. The cylinder 11 is fixed to the end of the insert plate housing 2, and the cylinder rod 13 of the cylinder 11 extends into the insert plate housing 2 and is connected to the first insert plate 5 or the second insert plate 6. By extending and retracting the cylinder rod 13 of the cylinder 11, the first insert plate 5 and the second insert plate 6 can be driven to move closer to or further away from each other.

[0036] Furthermore, the cylinder 11 is fixed to the end of the insert plate housing 2 by a fixing seat 12. The fixing seat 12 and the cylinder 11, as well as the fixing seat 12 and the insert plate housing 2, are fixedly connected by bolts, which ensures the connection strength while facilitating disassembly.

[0037] In this embodiment, both the first drive mechanism 3 and the second drive mechanism 4 include a plurality of cylinders 11 arranged side by side, preferably two. The two cylinders 11 arranged side by side jointly drive the first insert plate 5 or the second insert plate 6 to move, thereby enhancing the power output, achieving fast and smooth action, and improving the overall stability.

[0038] However, it should be noted that the cylinder 11 is not limited to having two, but can also have three or four, etc.; moreover, other drive mechanisms can be selected as needed, such as hydraulic cylinders or electric actuators, and the types of the first drive mechanism 3 and the second drive mechanism 4 can be the same or different.

[0039] In this embodiment, a limiting mechanism is also included, which is used to limit the movement of the first insert plate 5 and the second insert plate 6.

[0040] In a preferred embodiment, the limiting mechanism includes a limiting rod 7, a first limiting switch 9, and a second limiting switch 10. One end of the limiting rod 7 is connected to the end of the first insert plate 5 or the second insert plate 6 away from the center of the material discharge channel 1, and the other end of the limiting rod 7 extends out of the insert plate housing 2 and is connected to a sensing block 8. The first limiting switch 9 and the second limiting switch 10 are respectively disposed at the front and rear ends of the cylinder 11, and the sensing block 8 is located between the first limiting switch 9 and the second limiting switch 10. When the first limiting switch 9 or the second limiting switch 10 senses the sensing block 8, the cylinder 11 stops working and effectively limits the two insert plates.

[0041] This embodiment also provides a material unloading mechanism, which mainly includes the V-shaped insertion gate and the material unloading channel 1 as described above.

[0042] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
