Description

Technical Field

[0001] This utility model belongs to the field of protective coating production technology, specifically relating to a protective coating material silo. Background Technology

[0002] Protective coatings are a type of coating with special functions that can form a protective layer on the surface of materials, effectively resisting the effects of environmental factors such as corrosion, wear, high temperature or chemical erosion. They are widely used in fields such as construction, shipbuilding, bridges, chemical equipment and infrastructure. The processing and production of these coatings often involves the handling of a large amount of powdered raw materials. Due to their fine particles, poor flowability and easy moisture absorption and clumping, special protective coating material silos are required during storage and use to ensure a stable supply of materials and prevent quality deterioration. In existing technologies, the storage of protective coatings is mostly done using a closed silo structure, with discharge achieved through gravity or mechanical assistance. Some silos are equipped with simple stirring rods or vibrating devices in an attempt to improve the flowability of the powder. However, these devices usually have a limited range of action and are difficult to effectively intervene in the material state at the discharge port area. Especially after prolonged standing, the powdered raw materials are prone to bridging or arching at the outlet, leading to poor discharge or even complete blockage, which seriously affects production continuity and operational efficiency. Utility Model Content

[0003] In view of this, the present invention provides a protective coating hopper, which can continuously disturb and clear the discharge port area through an anti-blocking mechanism, effectively destroying the arch bridge structure, realizing a dynamic clearing process for the material, preventing arching and blockage during the discharge of the protective coating, ensuring smooth material discharge, significantly improving discharge stability and efficiency, reducing manual intervention, and extending the equipment operating cycle. At the same time, the design of the spiral blade diameter being smaller than the discharge end diameter avoids motion interference and ensures safe and reliable operation.

[0004] To address the aforementioned technical problems, this utility model provides a protective coating silo, comprising a silo for storing protective coatings. The silo's discharge end is equipped with a valve, and the inner cavity of the discharge end is equipped with an anti-blocking mechanism. The anti-blocking mechanism includes an installation rod disposed within the inner cavity of the discharge end of the silo. A sliding plate is slidably connected to the upper end of the installation rod, and a clearing head is provided at the upper end of the sliding plate. The clearing head has a vertically arranged elliptical structure, which continuously disturbs and clears the discharge area, effectively breaking the arch structure and realizing a dynamic clearing process. This prevents arching and blockage during the discharge of protective coatings, ensuring smooth discharge, significantly improving discharge stability and efficiency, reducing manual intervention, and extending equipment operating cycles. Simultaneously, the design of the spiral blade diameter being smaller than the discharge end diameter avoids motion interference, ensuring safe and reliable operation. The upper end of the mounting rod has an inverted conical structure, which is suitable for guiding materials downward and reducing accumulation.

[0005] The anti-blocking mechanism also includes a rotating rod rotatably connected to the lower end of the mounting rod. The outer arc surface of the rotating rod is provided with a spiral blade. The upper end of the rotating rod is connected to the lower end of the sliding plate through a connecting component. The outside of the hopper is also provided with a drive component for driving the rotating rod to rotate, thereby realizing the pushing effect on the surrounding materials.

[0006] The diameter of the spiral blades is smaller than the diameter of the discharge end of the hopper, which ensures that they do not interfere with the inner wall during rotation.

[0007] The connecting assembly includes a mounting groove at the lower end of the sliding plate, a connecting block fixedly mounted at the lower end of the sliding plate, and a reciprocating screw at the upper end of the rotating rod. The reciprocating screw engages with the rolling balls in the connecting block through a spiral groove, thereby converting the rotational motion into the reciprocating motion of the sliding plate along the axial direction of the mounting rod.

[0008] The drive assembly includes a bevel gear one located at the upper end of the rotating rod, a rotating rod rotatably connected to the transverse rod body of the mounting rod, and a bevel gear two located at the end of the rotating rod near the rotating rod. The bevel gear two meshes with the bevel gear one, thereby realizing power transmission.

[0009] The drive assembly also includes a motor located outside the hopper, with the motor's output shaft fixedly connected to the end of the rotating rod, which is used to provide rotational driving force for the rotating rod.

[0010] The mounting rod has a T-shaped cross-section and a hollow vertical rod body, which is used to provide an installation site for its auxiliary mechanisms.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. When the valve is opened, the drive assembly drives the rotating rod to rotate. The spiral blades on its outer arc surface generate a spiral propulsion effect on the protective coating in the discharge end of the hopper during rotation, effectively preventing material accumulation. At the same time, the unblocking head moves up and down in parallel, continuously disturbing and unblocking the discharge area. Especially when the material tends to arch, the elliptical structure of the unblocking head can effectively break the arch structure. The inverted conical structure at the upper end of the mounting rod can prevent the protective coating from accumulating. The entire anti-blocking mechanism realizes the dynamic unblocking process through the combined action of rotation and reciprocating motion, preventing arching and blockage when the protective coating is discharged, ensuring smooth discharge of the protective coating, significantly improving discharge stability and efficiency, reducing manual intervention, and extending the equipment operating cycle. At the same time, the design of the spiral blade diameter being smaller than the discharge end diameter avoids motion interference and ensures safe and reliable operation.

[0012] 2. The reciprocating screw connected to the upper end of the rotating rod drives the connecting block and the sliding plate to slide along the mounting rod under the rolling friction between the spiral groove and the balls in the connecting block, so that the unclogging head fixed on it can move up and down in sync, thus playing a role in rapid transmission.

[0013] 3. The motor starts and drives the rotating rod to rotate. Through the meshing transmission between bevel gear two and bevel gear one, the rotating rod rotates accordingly, thus providing a driving source for the rotating rod and playing a role in rapid driving of the rotating rod and its auxiliary mechanisms.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a protective coating material silo, such as Figure 1-4The diagram shows a silo 100 for storing protective coatings. The silo 100 has a valve 200 at its outlet end, which can be a slide gate valve. An anti-clogging mechanism is provided within the outlet end cavity of the silo 100. This mechanism includes an mounting rod 300 disposed within the outlet end cavity of the silo 100. A sliding plate 301 is slidably connected to the upper end of the mounting rod 300. The sliding plate 301 is rectangular, and the upper end of the vertical rod of the mounting rod 300 has a groove for providing sliding guidance support. A clearing head 302 is provided at the upper end of the sliding plate 301. The clearing head 302 has a vertically arranged elliptical structure. The upper end of the mounting rod 300 has an inverted conical structure to prevent the accumulation and retention of protective coating raw materials. The anti-clogging mechanism also includes a rotating rod 303 rotatably connected to the lower end of the mounting rod 300. The lower end of the vertical rod of the mounting rod 300 has a rotating hole for providing rotational support for the rotating rod 303. The outer arc surface of the rotating rod 303 is provided with a spiral blade 304. The upper end of the rotating rod 303 is connected to the lower end of the sliding plate 301 through a connecting assembly. The outside of the hopper 100 is also provided with a driving assembly for driving the rotating rod 303 to rotate. The diameter of the spiral blade 304 is smaller than the diameter of the discharge end of the hopper 100, which avoids motion interference and ensures the stability and smoothness of the discharge of raw materials for protective coating production. The connecting assembly includes an installation groove 400 set at the lower end of the sliding plate 301. A connecting block 401 is fixedly installed at the lower end of the sliding plate 301. The upper end of the rotating rod 303 is provided with a reciprocating screw 402. The reciprocating screw 402 is in rolling friction cooperation with the ball bearings set in the connecting block 401 through the spiral groove set on it. At the same time, the connecting block 401 is restricted by the sliding plate 301 and can only move vertically, thereby ensuring that the reciprocating screw 402 and the connecting block 401 can be smoothly transmitted and ensuring the reciprocating movement effect of the sliding plate 301.

[0018] When valve 200 is opened, the drive assembly drives the rotating rod 303 to rotate. The spiral blades 304 on its outer arc surface, during rotation, propel the protective coating inside the discharge end of the hopper 100, effectively preventing material accumulation. Simultaneously, the reciprocating screw 402 connected to the upper end of the rotating rod 303, through the rolling friction between its spiral groove and the balls in the connecting block 401, drives the connecting block 401 and the sliding plate 301 to slide along the mounting rod 300. This causes the unblocking head 302 fixed thereon to synchronously reciprocate up and down, continuously agitating and unblocking the discharge area, especially… When materials tend to arch, the elliptical unblocking head 302 can effectively break the arch structure. The inverted conical structure at the upper end of the mounting rod 300 can prevent the protective coating from accumulating. The entire anti-blocking mechanism realizes the dynamic unblocking process through the combined action of rotation and reciprocating motion, preventing arching and blockage when the protective coating is discharged, ensuring smooth discharge of the protective coating, significantly improving discharge stability and efficiency, reducing manual intervention, and extending the equipment operation cycle. At the same time, the design of the spiral blade 304 with a diameter smaller than the discharge end diameter avoids motion interference and ensures safe and reliable operation.

[0019] like Figure 1-4 As shown, the drive assembly includes a bevel gear 500 disposed on the upper end of the rotating rod 303, a rotating rod 501 rotatably connected to the transverse rod body of the mounting rod 300, a rotating slot for providing rotational support for the rotating rod 501 provided in the transverse rod body of the mounting rod 300, a bevel gear 502 disposed at the end of the rotating rod 501 near the rotating rod 303, the bevel gear 502 meshing with the bevel gear 500, and the drive assembly also includes a motor 503 disposed outside the hopper 100, the output shaft of the motor 503 being fixedly connected to the end of the rotating rod 501.

[0020] The motor 503 starts and drives the rotating rod 501 to rotate. Through the meshing transmission between the second bevel gear 502 and the first bevel gear 500, the rotating rod 303 rotates accordingly, thus providing a driving source for the rotating rod 303.

[0021] like Figure 2-4 As shown, the mounting rod 300 has a T-shaped cross-section and a hollow vertical rod body, which is used to provide an installation site for its auxiliary mechanisms.

[0022] The working principle of the protective coating silo provided by this utility model is as follows: During the processing of the protective coating, the discharge end of the powdered raw material silo 100 is aligned with the designated position. Then, the valve 200 is opened, the motor 503 is started, and the rotating rod 501 is rotated. Through the meshing transmission of the bevel gear 2 502 and the bevel gear 1 500, the rotating rod 303 rotates accordingly. During the rotation, the spiral blades 304 on its outer arc surface generate a spiral propulsion effect on the protective coating in the discharge end of the silo 100, effectively preventing material accumulation. At the same time, the reciprocating screw 402 connected to the upper end of the rotating rod 303, under the rolling friction cooperation between its spiral groove and the balls in the connecting block 401, drives the connecting block 401 and the sliding plate 301 along the installation... The sliding of rod 300 causes the unblocking head 302 fixed on it to move up and down in sync, continuously disturbing and unblocking the discharge port area. Especially when the material tends to arch, the elliptical unblocking head 302 can effectively break the arch structure. The inverted conical structure at the upper end of the mounting rod 300 can prevent the protective coating from accumulating. The entire anti-blocking mechanism realizes the dynamic unblocking process through the combined action of rotation and reciprocating motion, preventing arching and blockage when the protective coating is discharged, ensuring smooth discharge of the protective coating, significantly improving discharge stability and efficiency, reducing manual intervention, and extending the equipment operating cycle. At the same time, the design of the spiral blade 304 with a diameter smaller than the discharge end diameter avoids motion interference and ensures safe and reliable operation.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
