Description

Technical Field

[0001] The utility model relates to the technical field of double one-way valves, in particular to a double one-way valve for bag dust removal. Background Art

[0002] In a bag-type dust collector, small particles of flue gas flow from the outside of the bag to the inside, and the solid dust particles in the flue gas on the outer surface of the bag are filtered. As the flue gas is continuously filtered, the dust particles on the outer surface of the bag will continue to accumulate, resulting in increased air resistance. In order to keep the pressure drop of the bag-type dust collector at a reasonable level, the bags need to be cleaned regularly. This is usually done by intermittently spraying compressed air into the bag through a compressed air pipe above the bag to flush out the accumulated dust particles.

[0003] The double check valve for dust bag is a component used in bag dust collectors. The function of the double check valve for dust bag dust collection is to control the direction of the airflow in the cleaning system so that the compressed air can only be blown out of the filter bag outlet in one bag and cannot be blown in from the inlet of other bags. This ensures that the cleaning airflow can only act on the filter bag that needs to be cleaned without affecting other bags. This design can improve the cleaning effect, extend the service life of the filter bags, reduce energy consumption, and improve dust removal efficiency. The double check valve needs to be installed at a certain position. The mounting bracket usually has reserved screw holes, and the bracket can be fixed to the bag dust collector with bolts.

[0004] However, in the process of realizing the embodiments of the utility model, the inventors found that there are at least the following defects in the background technology: when the double check valve used in the existing bag dust collector is used, it is usually necessary to open a corresponding thread groove on the bag structure or the supporting structure of the bag to bolt and fix the double check valve, and the bag and the supporting structure need to resist the impact of airflow. The opening of holes can easily weaken their resistance and cause damage to the bag dust collector. Therefore, we propose a double check valve for bag dust collector to solve this problem.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A double one-way valve for dust bag removal comprises a bag mechanism 1 and a mounting cylinder 2. The bag mechanism 1 comprises a bag body and a fixed sleeve. The top of the mounting cylinder 2 is connected with a double one-way valve body 3. The mounting cylinder 2 sliding sleeve is arranged on the outside of the bag mechanism 1. A hook plate 4 is rotatably installed on the bottom of the mounting cylinder 2. A pushing ring 5 is provided on the outer sliding sleeve of the mounting cylinder 2. A plurality of vertical grooves are opened on the inner side of the pushing ring 5. A plurality of short plates 7 are fixedly installed on the outer side of the mounting cylinder 2. The same limit spring 8 is fixedly installed between the top of the short plate 7 and the top inner wall of the corresponding vertical groove. A connecting plate 6 is rotatably installed on the bottom of the mounting cylinder 2. One side of the connecting plate 6 is rotatably connected with the corresponding hook plate 4.

[0023] In the utility model, a sealing ring 9 is fixedly installed on the inner wall of the installation tube 2, and the sealing ring 9 is slidingly and sealingly connected to the outer side of the bag mechanism 1. The setting of the sealing ring 9 prevents air flow from the gap between the installation tube 2 and the bag mechanism 1.

[0024] In the utility model, a plurality of spring pieces 10 are fixedly mounted on the top inner wall of the mounting tube 2, and the spring pieces 10 are movably abutted against the inner wall of the bag mechanism 1. The plurality of spring pieces 10 are arranged in a circular array with equal spacing, and the spring pieces 10 abut against the inner wall of the bag mechanism 1, thereby improving the installation stability of the mounting tube 2.

[0025] In the utility model, short grooves are provided on one side of two of the multiple short plates 7, and a built-in groove is provided on the inner wall of one side of the corresponding vertical groove. An insert plate 11 is movably connected in the short plate 7, and a pull handle 12 is fixedly installed on one side of the insert plate 11. The connection between the insert plate 11 and the short groove limits the push ring 5 from moving upward, thereby improving the stability of the hook plate hook clamp cloth bag catching mechanism 1.

[0026] In the utility model, a return spring 13 is fixedly installed on one side of the plug board 11 , and one end of the return spring 13 is fixedly connected to an inner wall of one side of the corresponding built-in groove, so as to limit the plug board 11 .

[0027] In the present invention, the double check valve body 3 includes two check valve tubes 14. The flow direction of the check valve tube 14 located on the top is from the outside to the double check valve body 3, and the flow direction of the check valve tube 14 located on the left is from the double check valve body 3 to the outside.

[0028] It should be noted that the double one-way valve body 3 can control forward and reverse flow at the same time to ensure that the airflow can only flow in one direction. When the airflow flows from one side to the other, the corresponding one-way valve opens and the other one-way valve closes to prevent the airflow from flowing in the opposite direction.

[0029] The working principle of the utility model is as follows: by pushing the ring 5 and cooperating with the plurality of connecting plates 6, pressure is applied to the plurality of hook plates 4, so that the hook plates 4 are tightly abutted against the bottom of the fixing sleeve, and the friction between the plurality of spring sheets 10 and the inner wall of the fixing sleeve limits the upward movement of the mounting tube 2, and the cooperation between the plug plate 11 and the short groove limits the upward movement of the pushing ring 5, thereby improving the stability of the installation of the mounting tube 2 and the bag mechanism 1, and preventing the upward airflow from impacting the mounting tube 2 and causing the mounting tube 2 to be detached. When the mounting tube 2 needs to be disassembled, the two pull handles 12 are pulled outward, thereby driving the plug plate 11 to move outward and detach from the short groove, and then moving the pushing ring 5 upward. The pushing ring 5 drives the hook plate 4 to rotate upward by cooperating with the plurality of connecting plates 6, so that the hook plate 4 is separated from the bag mechanism 1.

[0030] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
