Description

Technical Field

[0001] This utility model relates to the field of airlock technology, and in particular to an airlock with adjustable gap. Background Technology

[0002] Airlocks are primarily used to change and control the direction and speed of airflow. They can also be used in pneumatic conveying of solid granules, powders, and ultrafine powders, dust removal systems, and other processes for feeding and unloading materials. The working principle of an airlock is mainly to change the direction and speed of airflow through the movement of control devices. Specifically, it utilizes the kinetic energy and pressure difference of the airflow to control it. When the airlock is closed, airflow cannot pass through; when it needs to be opened, external force or a driving mechanism such as an electric motor acts on the airlock, causing it to begin rotating or moving, at which point airflow gradually passes through; when the airlock is fully open, airflow can pass freely; conversely, when it needs to be closed, the external force is stopped, and the airlock begins to rotate or move in the opposite direction, gradually blocking airflow.

[0003] There is a certain gap between the blades and the shell of the existing airlock. When transporting small particles, irregular material flow can easily enter the gap between the rotating blades and the shell, resulting in material jamming or flattening. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable gap airlock.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The adjustable elastic component includes a first arc block component and two symmetrically arranged second arc block components. A fixed connecting arc block is provided between the first arc block component and the two symmetrically arranged second arc block components, and the fixed connecting arc block is connected and fixed to the first arc block component and the two second arc block components by multiple fixing bolts.

[0008] Furthermore, in a preferred configuration, the first arc block assembly includes a first elastic arc block body, and a fixing mounting block is installed on one side of the first elastic arc block body.

[0009] Furthermore, in a preferred configuration, the second arc block assembly includes a second elastic arc block body, and a T-shaped limiting block is mounted on one side of the second elastic arc block body.

[0010] In addition, a preferred structure is that multiple grooves are equally spaced on one side of the fixed mounting block and the T-shaped limiting block, and spring assemblies are horizontally installed in the grooves.

[0011] Furthermore, in a preferred configuration, the spring assembly includes a fixed rod portion and a limiting rod portion. The limiting rod portion is slidably disposed within the fixed rod portion, and a fixing ring is installed at one end of both the fixed rod portion and the limiting rod portion. A spring body is sleeved between the two fixing rings and outside the fixed rod portion and the limiting rod portion.

[0012] In addition, a preferred structure is that embedded grooves are provided on both sides of the outer wall of the first arc block assembly and on one side of the outer wall of the two second arc block assemblies.

[0013] In addition, a preferred structure is that a locking groove is provided at the middle of one end of the blade body at the fixed mounting block, the depth of the locking groove is greater than the width of the fixed mounting block, and locking grooves are provided on both sides of the locking groove and at the T-shaped limiting block at one end of the blade body.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the first arc block assembly and two symmetrically arranged second arc block assemblies are used to fill the gap between the blade assembly and the airlock body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An adjustable gap airlock includes an airlock body 1, which includes a blade assembly 2. The blade assembly includes an impeller body, and multiple blade bodies are evenly installed on the outer wall of the impeller body. An adjustable elastic component 3 is provided at one end of the blade body. It is worth noting that the specific structure, connection method and working principle of the airlock body 1 and the blade assembly 2 are all existing technologies that are currently disclosed in the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0024] Furthermore, the adjustable elastic component 3 includes a first arc block component 31 and two symmetrically arranged second arc block components 32. A fixed connecting arc block 33 is provided between the first arc block component 31 and the two symmetrically arranged second arc block components 32, and the fixed connecting arc block 33 is connected and fixed to the first arc block component 31 and the two second arc block components 32 by a plurality of fixing bolts 34.

[0025] Meanwhile, the first arc block assembly 31 includes a first elastic arc block body 311, and a fixed mounting block 312 is installed on one side of the first elastic arc block body 311.

[0026] Meanwhile, the second arc block assembly 32 includes a second elastic arc block body 321, and a T-shaped limiting block 322 is installed on one side of the second elastic arc block body 321.

[0027] Furthermore, it is worth noting that the outer walls of the first elastic arc block body 311 and the second elastic arc block body 321 are coated with a wear-resistant coating to enhance their wear resistance.

[0028] Furthermore, multiple grooves are equally spaced on one side of the fixed mounting block 312 and the T-shaped limiting block 322, and spring assemblies 35 are horizontally installed in the grooves.

[0029] Furthermore, the spring assembly 35 includes a fixed rod portion 352 and a limiting rod portion 353. The limiting rod portion 353 is slidably disposed within the fixed rod portion 352, and a fixing ring 351 is installed at one end of both the fixed rod portion 352 and the limiting rod portion 353. A spring body 354 is sleeved between the two fixing rings 351 and outside the fixed rod portion 352 and the limiting rod portion 353.

[0030] Furthermore, embedded grooves are provided on both sides of the outer wall of the first arc block assembly 31 and on one side of the outer wall of the two second arc block assemblies 32.

[0031] Furthermore, a locking groove 21 is provided at the middle of one end of the blade body at the fixed mounting block 312. The depth of the locking groove 21 is greater than the width of the fixed mounting block 312. A locking groove 22 is provided on both sides of the locking groove and at the T-shaped limiting block 322 at one end of the blade body. The depth of the locking groove 22 is greater than the width of the T-shaped limiting block 322.

[0032] Furthermore, it is worth noting that when the second arc block assembly 32 slides symmetrically along the locking groove to the corresponding locking slot, its first arc block assembly 31 is locked into the locking groove 21. At this time, the two sides of its first elastic arc block body 311 are respectively attached to the corresponding second elastic arc block body 321. Then, the fixed connecting arc block 33 is locked into the embedded groove of the first elastic arc block body 311 and the second elastic arc block body 321 and is connected and fixed by the fixing bolt 34. At this time, its fixed connecting arc block 33 is flush with the outer wall of the first elastic arc block body 311 and the second elastic arc block body 321, and the outer wall of the fixed connecting arc block 33 is coated with a wear-resistant coating.

[0033] In this embodiment, after the second arc block assembly 32 slides symmetrically along the locking groove to the corresponding locking slot, its first arc block assembly 31 is locked into the locking groove 21. At this time, the two sides of its first elastic arc block body 311 are respectively attached to the corresponding second elastic arc block body 321. Then, the fixed connecting arc block 33 is locked into the embedded groove of the first elastic arc block body 311 and the second elastic arc block body 321 and is fixed by fixing bolts 34. At this time, its fixed connecting arc block 33 is flush with the outer wall of the first elastic arc block body 311 and the second elastic arc block body 321, and the outer wall of the fixed connecting arc block 33 is coated with a wear-resistant coating.

[0034] When the T-shaped limiting block 322 of the second arc block assembly 32 is located in the locking groove, and the fixing mounting block 312 of the first elastic arc block body 311 is located in the locking groove 21, the second elastic arc block body 321 is always outward under the action of the spring assembly 35. When the second elastic arc block body 321 is in contact with the inner wall of the airlock body 1, the second elastic arc block body 321 drives the T-shaped limiting block 322 to contact the blade, and the spring body 354 of the spring assembly 35 is in a tensioned and compressed state. The first elastic arc block body 311 is always outward under the action of the spring assembly 35. When the first elastic arc block body 311 is in contact with the inner wall of the airlock body 1, the first elastic arc block body 311 drives the fixing mounting block 312 to contact the blade, and the spring body 354 of the spring assembly 35 is in a tensioned and compressed state.

[0035] When the outer walls of the first elastic arc block body 311 and the second elastic arc block body 321 wear down, gaps appear between the first elastic arc block body 311, the second elastic arc block body 321 and the inner wall of the airlock body 1. The spring body 354 of the spring assembly 35 gradually relaxes and rebounds under its own action, so that the outer walls of the first arc block assembly 31 and the two second arc block assemblies 32 always fit against the inner wall of the airlock body 1.

[0036] Furthermore, when the first arc block assembly 31 and the two second arc block assemblies 32 are detachable, they can be disassembled and replaced after a period of use.

[0037] In this invention, the first arc block assembly 31 and two symmetrically arranged second arc block assemblies 32 are configured to fill the gap between the blade assembly 2 and the airlock body 1. Under the action of the spring assembly 35, the outer walls of the first arc block assembly 31 and the two second arc block assemblies 32 are always in contact with the inner wall of the airlock body 1, which can significantly reduce the gap between the blade assembly and the airlock body and effectively prevent air, dust or other fluids from leaking out of the gap during equipment operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
