Description

Technical Field

[0001] The utility model relates to the technical field of blockage clearing equipment, in particular to a jetting blockage clearing device with adjustable impact angle. Background Art

[0002] The storage of raw materials and the continuous supply of materials are crucial components of the material processing and logistics industries. Silos play a crucial role and can be categorized by type: silos, hoppers, hoppers, storage bins, and containers. Silo designs must meet the following three requirements: 1. They must be able to store a specified amount of material; 2. They must be strong enough to withstand the pressure generated by the material within the silo as well as the forces exerted on them by the natural environment; and 3. During unloading, the material must flow smoothly and evenly from the silo outlet at a uniform and controllable rate. Therefore, material flowability within the silo is a key indicator of silo performance. However, in actual production, due to various reasons, some silos can exhibit poor material flowability, resulting in poor discharge and the occurrence of arching, bridging, rat-holes, and adhesion. These problems hinder material discharge, disrupting production continuity and even causing accidents, impacting production safety, food safety, and the company's economic profitability. Improving silo arch prevention and reducing storage accidents have become significant challenges in silo manufacturing and production. Therefore, a jet clearing device with an adjustable impact angle is proposed.

[0003] The blockage clearing device in the prior art mainly uses vibration or air force to destroy the formation of the arch, thereby achieving an effective blockage clearing effect on the internal blockage structure, and clearing the internal blocked material by vibrating the outer wall of the structure and by using air pressure jets to the inside.

[0004] The blockage clearing device in the existing technology has certain shortcomings. First, clearing the blockage by vibration will cause damage to the internal structure and the effect is not good enough. Second, the blockage clearing process is cumbersome and can only work on one position, and cannot achieve better multi-angle adjustment effects. It has a low applicability and low efficiency. Utility Model Content

[0007] As a further description of the above technical solution: the inner wall of the connector is fixedly connected to a wall surface, and the large nut and the small nut cooperate with each other to achieve tightening;

[0008] As a further description of the above technical solution: the spring is arranged on the periphery of the cylindrical end of the valve core, and the valve core is slidably connected relative to the valve body;

[0009] As a further description of the above technical solution: the valve body and the valve core are located on the same center line, and the large nut, the small nut, and the compression spring sleeve move as a whole;

[0010] As a further description of the above technical solution: the valve body and the guide sleeve are relatively stationary, and the round nut is arranged on the outer wall of the valve body;

[0011] As a further description of the above technical solution: the two sides of the valve core are cylindrical and conical respectively, the diameter of the cylindrical side of the valve core is smaller than the diameter of the cylindrical side of the guide sleeve, and the valve core is slidably connected to the inside of the guide sleeve;

[0012] As a further description of the above technical solution: the valve core includes two types: radial type and impact type, and the hexagonal nut and the connector are in a welding relationship.

[0013] The utility model has the following beneficial effects:

[0014] 1. The present invention utilizes a pneumatic cleaning method through a spraying structure during connection, which does not cause damage, vibration, stress, or wear to the container wall.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figures 1-6 The utility model provides an embodiment: a jet clearing device with adjustable impact angle, including a valve body 1, realizing the integrity of the entire structure, the inner wall of the valve body 1 is fixedly connected with a guide sleeve 3, realizing the limiting effect on the position of the valve core 2, the inner wall of the guide sleeve 3 is slidably connected with the valve core 2, realizing the internal sealing and angle change effect, the bottom end of the valve core 2 is installed with a compression spring sleeve 6, realizing the fixing and position limiting effect of the spring 7, and a spring 7 is arranged between the compression spring sleeve 6 and the guide sleeve 3, realizing the effect of pulling the valve core 2 back after the position of the valve core 2 is changed. A large nut 8 is provided on the other side of the compression spring sleeve 6, and a small nut 9 is installed on the other side of the large nut 8. The function of the two nuts is to achieve a better fixing effect and to connect the spring 7 to the valve core 2. A round nut 5 is provided on the outer wall of the valve body 1, and a hexagonal nut 4 is provided on one side of the round nut 5, so as to achieve the effect of external connection and fixation of the entire blowing assembly. The outer wall of the hexagonal nut 4 is fixedly connected with a connector 10 to achieve the effect of fixed connection with the hexagonal nut 4. The above structure constitutes a blowing assembly, and the blowing assembly is used for the function of spraying and clearing blockage.

[0029] The inner wall of the connector 10 is fixedly connected to the wall surface 12 , and the large nut 8 and the small nut 9 cooperate with each other to achieve fastening, thereby achieving a stable fixed connection effect.

[0030] The spring 7 is arranged on the periphery of the cylindrical end of the valve core 2, and the valve core 2 is slidably connected relative to the valve body 1, thereby achieving a better movement effect and ensuring the movement effect of the valve core 2.

[0031] Reference Figures 1-6 The valve body 1 and the valve core 2 are on the same center line, which achieves a sealing effect to a certain extent. The large nut 8, the small nut 9, and the compression spring sleeve 6 move as a whole to achieve a better movement effect. The valve body 1 and the guide sleeve 3 are relatively stationary, and the fixed connection ensures the sealing. The round nut 5 is arranged on the outer wall of the valve body 1. The two sides of the valve core 2 are cylindrical and conical respectively, which realizes the effect of sealing one side of the valve body 1. The diameter of the cylindrical side of the valve core 2 is smaller than the diameter of the cylindrical side of the guide sleeve 3, and is slidably connected to the inside of the guide sleeve 3.

[0032] Reference Figure 6-Figure 9The valve core 2 includes two types: radial type and impact type. The hexagonal nut 4 and the connector 10 are welded to achieve an external connection relationship and achieve different effects.

[0033] Working principle: Before use, the valve core 2 is pressed tightly against the valve body 1. When the silo is blocked, high-pressure gas is introduced into the left side of the valve body 1. The gas flows from the valve body 1 to the right side. The high-pressure gas pushes open the valve core 2 at the right end, and the gas is quickly ejected to impact the blocked material, causing the material to flow again. After one ventilation, the air pressure in the valve body decreases. Due to the action of the spring 7, the valve core 2 rebounds and is re-pressed against the valve body 1 to achieve immediate resealing, preventing nozzle blockage and material accumulation. Changing the preload of the spring 7 can adjust the opening degree of the valve core 2. The appropriate opening degree can be selected according to the material properties and blockage situation. The spray clearing device is installed on the silo wall 12. Using the valve core 2, each spray clearing device sprays high-pressure, high-volume compressed air straight ahead to cause the blocked and arched material in the silo to flow again.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
