Description

Technical Field

[0001] This utility model relates to the field of filter bag unclogging technology, specifically a filter bag with a built-in rapid unclogging mechanism. Background Technology

[0002] Unblocking mechanisms typically refer to devices or systems used to remove blockages from equipment or pipelines. Their purpose is to maintain the normal operation of equipment and prevent blockages from affecting production or function.

[0003] Existing filter bag cleaning mechanisms typically use pulse jets to remove dust accumulated on the inner wall of the filter bag. However, since the pulse valve is not directly fixed above the filter bag, it cannot accurately clean the filter bag. When condensation occurs on the inner wall of the filter bag, the condensation combines with the dust and sticks to the inner wall of the filter bag. At this time, the pulse valve cannot effectively clean the filter bag, which leads to damage inside the filter bag and affects its use.

[0004] Therefore, a filter bag with a built-in rapid unclogging mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filter bag with a built-in rapid unclogging mechanism, which can solve problems such as the inability of pulse valves to remove adhesive residue from the inner wall of the filter bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a dust collector housing and an outlet pipe extending through the upper end of the dust collector housing. Several outlet pipes have air chambers at their upper ends, each air chamber has a pulse valve at its upper end, one of the pulse valves has an air pipe at its lower end, and the air pipe has a flexible hose at its lower end. A pipe support ring is fitted inside the flexible hose. A fixing plate is installed inside the dust collector housing, and several filter bags are installed inside the fixing plate. An exhaust pipe is installed on one side of the dust collector housing.

[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. 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.

[0023] Example:

[0024] Please see Figure 1 - Figure 4In this embodiment, a filter bag with a built-in rapid unclogging mechanism includes a dust collector housing 1 and an outlet pipe 2 that runs through the upper end of the dust collector housing 1. The feature is that an air tank 3 is provided at the upper end of several outlet pipes 2, and a pulse valve 5 is provided at the upper end of each air tank 3. An air pipe 11 is provided at the lower end of one of the pulse valves 5, and a flexible hose 6 is provided at the lower end of the air pipe 11. A pipe support ring 10 is embedded inside the flexible hose 6. A fixing plate 9 is provided inside the dust collector housing 1, and several filter bags 8 are provided inside the fixing plate 9. An exhaust pipe 7 is provided on one side of the dust collector housing 1.

[0025] The ability of the air tank 3 to provide stable air pressure, thus ensuring that the intensity and effect of each pulse valve 5 spray are consistent, is an existing technology and therefore has not been described in detail in this embodiment.

[0026] When pulse valve 5 receives a dust removal command and opens, compressed air from air tank 3 is instantly ejected at high speed through pulse valve 5. The high-speed airflow directly enters the filter bag 8 through the blowpipe. The powerful impact of the airflow causes the filter bag 8 to expand rapidly, and the inner wall of the filter bag 8 undergoes radial deformation. Because the adhesion between the dust adhering to the surface of the filter bag 8 and the filter bag 8 is broken under the rapid expansion and vibration of the filter bag 8, the dust is peeled off from the inner wall of the filter bag 8. At the same time, the compressed air ejected by pulse valve 5 induces surrounding air to enter the filter bag 8, enhancing the dust removal effect. The peeled dust falls into the ash hopper below under gravity, completing the dust removal process. However, when condensation appears on the inner wall of the filter bag 8, and the condensation combines with dust and adheres to the inner wall of the filter bag 8, pulse valve 5 cannot effectively remove the dust by ejecting high-speed airflow. This effectively removes the dust accumulated on the inner wall of the filter bag 8. By closing the other pulse valves 5 and activating the pulse valve 5 at the upper end of the air pipe 11, the pulse valve 5 at the upper end of the air pipe 11 concentrates the gas flow of the other pulse valves 5. The pulse valve 5 injects high-speed airflow into the air pipe 11. By manually holding the air pipe 11 and blowing air into the clogged filter bag 8, the high-speed airflow blown into the filter bag 8 causes the filter bag 8 to oscillate rapidly with expansion and contraction. This oscillation is transmitted to the attached dust, further disrupting the adhesion between the dust and the inner wall of the filter bag 8, thus achieving the effect of removing the dust accumulated on the inner wall of the filter bag 8.

[0027] The support ring 10, which is fitted into the inner wall of the hose 6, can provide support for the hose 6. The support ring 10 can withstand external pressure and internal medium pressure, preventing the hose 6 from deforming, wrinkling, or collapsing under pressure. When the hose 6 is bent, it obstructs the airflow, causing the gas flow rate to decrease. When the flow rate is lower than the threshold required for effective unclogging, it cannot generate sufficient impact force and dust carrying capacity, thus failing to completely remove the accumulated dust from the inner wall of the filter bag 8, resulting in incomplete unclogging.

[0028] The outlet pipe 2 and the air bag 3 are connected through each other, and the upper end of the outlet pipe 2 is snapped into the output end of the pulse valve 5;

[0029] The air pipe 11 and the hose 6 are connected, and the fixing plate 9 is fixedly connected to the inner wall of the dust collector housing 1 on both sides;

[0030] The cloth bag 8 and the fixing plate 9 are connected through each other, and the cloth bag 8 is fitted and connected inside the fixing plate 9;

[0031] By inserting the outlet pipe 2 inside the air tank 3, the air tank 3 can stabilize the airflow inside the outlet pipe 2, preventing high-speed airflow from damaging the outlet pipe 2. Furthermore, by connecting the upper end of the outlet pipe 2 to the output end of the pulse valve 5, the pulse valve 5 can directly supply air to the outlet pipe 2, reducing gas loss during the supply process and thus affecting air pressure and dust removal efficiency. By connecting the air pipe 11 and the flexible hose 6, the flexible hose 6 transmits the gas from the air pipe 11 to the filter bag 8, achieving the effect of cleaning the inner wall of the filter bag 8. The flexible hose 6 is highly flexible, can be bent and twisted, and can adapt to complex spaces and equipment layouts. It can freely change its shape and position according to the complex environment inside the dust collector housing 1, preventing the problem of ineffective manual cleaning of dust accumulated on the inner wall of the filter bag 8 due to the complex internal structure of the dust collector housing 1.

[0032] By fitting the filter bag 8 into the inside of the fixing plate 9 and fixing the two sides of the fixing plate 9 into the inside of the dust collector housing 1, the fixing plate 9 can fix the arrangement position of the filter bag 8 so that the outlet pipe 2 above the filter bag 8 can directly blow air onto the inner wall of the filter bag 8, thus improving the accuracy of unclogging.

[0033] The length of the cloth bag 8 at the upper end of the fixing plate 9 is less than the length of the lower end of the fixing plate 9, and several cloth bags 8 are all set below several through-tubes 2;

[0034] The exhaust pipe 7 is connected to the dust collector housing 1;

[0035] By setting the length of the filter bag 8 at the upper end of the fixed plate 9 to be less than the length at the lower end of the fixed plate 9, interference between the filter bag 8 and the blowing of the outlet pipe 2 can be avoided, leaving enough space for convenient operation. At the same time, it can reduce the risk of shaking and falling off the filter bag 8 due to uneven internal force, ensuring the reliability of equipment operation. By placing the filter bag 8 below the outlet pipe 2, the inner wall of the filter bag 8 can be directly cleaned by the outlet pipe 2, improving the efficiency of cleaning. In particular, by setting the exhaust pipe 7 to be connected to the dust collector housing 1, when the acidic gas overflowing from the filter bag 8 is discharged into the dust collector housing 1, the acidic gas inside the dust collector housing 1 will be filtered through the exhaust pipe 7 and discharged to the outside, preventing the acidic gas from accumulating inside the dust collector housing 1 for a long time and causing damage to the outlet pipe 2.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, high-speed gas is ejected through pulse valve 5. The ejected gas is delivered to the inside of the filter bag 8 through the outlet pipe 2, thereby cleaning the dust accumulated on the inner wall of the filter bag 8. When the dust accumulated inside the filter bag 8 combines with condensation, it will stick to the inner wall of the filter bag 8. The outlet pipe 2 cannot effectively clear the blockage on the inner wall of the filter bag 8. At this time, by closing the other pulse valves 5 and activating the pulse valve 5 at the upper end of the air pipe 11, the pulse valve 5 will gather the pressure of the other pulse valves 5 to deliver a high-speed airflow into the air pipe 11. The air is then manually blown into the inner wall of the filter bag 8 through the handheld hose 6 to achieve the effect of clearing the blockage.

[0038] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0039] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
