Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a dust collector bag leakage rapid detection device. Background Art

[0002] Bag filter is a kind of industrial waste gas purification equipment, used to capture particulate matter and other smoke dust entrained in the gas. It is suitable for collecting fine and dry dust and is the main equipment for gas treatment in industrial enterprises. It is an important environmental protection tool to reduce environmental pollution and improve air quality.

[0003] The dust bag is the core of the bag filter and the key part that restricts the operation effect of the dust collector. When the dust removal efficiency of the dust collector decreases and smoke appears in the chimney, the integrity of the bag in the box should be checked first. The possible reasons are that the bag is seriously worn and leaks or the bag falls off as a whole, causing dust and other particles to enter the clean air chamber, which is easy to cause environmental pollution and easily cause the online detection index of particles to exceed the standard, causing environmental risks for the enterprise.

[0004] Existing bag filter leakage detection devices, such as Chinese patent document CN 213668337 U, etc., are mostly complex in structure and require an external power source to extract the output gas of the bag filter. The vibration generated when the bag filter is working will inevitably affect the external power source and the connection part of the device, thereby increasing the maintenance and operation cost of the device.

[0005] Therefore, there is an urgent need for a detection device that does not require an external power source to meet the requirements of leakage detection during the operation of the bag filter. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a dust collector bag leakage rapid detection device, which does not require the use of an external power source and has a simple structure, making it easy for operators to promptly detect leakage and perform maintenance.

[0007] In order to achieve the above technical effects, the utility model adopts the following technical solutions:

[0008] A dust collector bag leakage rapid detection device comprises a bag dust collector and a detection component, wherein the bag dust collector comprises a clean air outlet pipe, the detection component is arranged on the bottom surface of the clean air outlet pipe of the bag dust collector, and a through hole for fixing the detection component is opened on the clean air outlet pipe.

[0009] The detection assembly includes a guide plate, a connecting tube and a collecting bottle which are connected in sequence from top to bottom. The guide plate is located inside the clean gas outlet pipe. The guide plate is U-shaped and bends toward the clean gas outlet. The connecting tube is fixed at the through hole. The connection between the collecting bottle and the connecting tube is a detachable connection. The collecting bottle is made of a transparent material.

[0010] The rapid detection device provided by the utility model does not require the use of an external power source. The U-shaped guide plate arranged inside the clean gas outlet pipe produces a disturbing effect on the clean gas flowing through, while not affecting the discharge of the clean gas from the clean gas outlet pipe; when a bag leak occurs, the dust particles carried in the clean gas are disturbed and then settle, and the dust at the guide plate enters the transparent collection bottle from the connecting tube, so that the operator can observe the leakage conveniently. At the same time, the detachable connection method of the collection bottle allows the operator to clean the detection component, especially the side of the guide plate facing the clean gas, the inner wall of the connecting tube and the inner wall of the collection bottle in time after discovering the leakage, so as to ensure that the inside of the detection component is dust-free and does not affect the subsequent detection of the leakage.

[0011] Preferably, the height of the guide plate is 1 / 3-1 / 2 of the inner height of the clean gas outlet pipe; the width of the guide plate is 1 / 10-1 / 6 of the inner width of the clean gas outlet pipe.

[0012] By controlling the size of the guide plate, the dust settling effect is ensured while the clean air discharge process is not affected.

[0013] Preferably, the lower portion of the guide plate is closed. By closing the lower portion of the guide plate, the dust settled by the turbulent flow can be easily guided to the collection bottle.

[0014] Preferably, the detection component further comprises a spoiler baffle, wherein the spoiler baffle is arranged upstream of the guide plate relative to the direction of the net air flow.

[0015] Further preferably, the spoiler baffles include two spoiler baffles symmetrically arranged with the guide plate as the center, and the spoiler baffles are fixed to the bottom surface of the inner wall of the clean air outlet pipe.

[0016] More preferably, the width and height of the spoiler baffle are the same as the width and height of the guide plate.

[0017] By arranging spoiler baffles on both sides upstream of the guide plate, the clean air flowing through is first disturbed by the spoiler baffles, resulting in rotation in the direction of the guide plate. When bag leakage occurs, the dust carried in the clean air is gathered at the location of the guide plate. When the clean air flows through the guide plate, the dust can be settled more concentratedly, thereby improving the detection effect of leakage.

[0018] Preferably, the connecting tube has a smooth inner wall, so as to ensure that the dust settled at the guide plate can smoothly enter the collection bottle, so as to facilitate accurate judgment of the leakage situation.

[0019] Preferably, the detection component also includes an alarm component, which includes a dust concentration sensor, a PLC and an alarm. The dust concentration sensor is located in a collection bottle, and the PLC is electrically connected to the dust concentration sensor and the alarm, respectively. The PLC controls the alarm according to the data measured by the dust concentration sensor.

[0020] By setting up an alarm component, the patrol burden of operators can be effectively reduced. When the alarm sounds, the operator can handle the bag dust collector where the alarm detection component is located.

[0021] Further preferably, the PLC is also electrically connected to the bag dust collector, and the PLC controls the start and stop of the bag dust collector according to data measured by the dust concentration sensor.

[0022] When bag leakage occurs, if the operator fails to close the corresponding bag dust collector in time, the dust-carrying gas will be discharged into the atmosphere, causing environmental pollution. Automatic control of the bag dust collector through PLC can effectively control the pollution.

[0023] Beneficial effects of the utility model:

[0024] 1. The rapid detection device provided by the utility model does not require the use of an external power source. The U-shaped guide plate arranged inside the clean air outlet pipe produces a disturbing effect on the clean air flowing through, while not affecting the discharge of the clean air from the clean air outlet pipe; when a bag leak occurs, the dust particles carried in the clean air are disturbed and then settle, and the dust at the guide plate enters the transparent collection bottle from the connecting tube, making it convenient for the operator to observe the leakage. At the same time, the detachable connection method of the collection bottle allows the operator to clean the detection component, especially the side of the guide plate facing the clean air, the inner wall of the connecting tube and the inner wall of the collection bottle in time after discovering the leakage, to ensure that the inside of the detection component is dust-free and does not affect the subsequent detection of the leakage.

[0025] 2. The rapid detection device provided by the utility model controls the size of the guide plate to ensure the dust settling effect while ensuring that the discharge process of the clean air is not affected.

[0026] 3. The rapid detection device provided by the utility model effectively reduces the patrol burden of the operator by setting an alarm component. When the alarm sounds, the operator can handle the bag dust collector where the alarm detection component is located; when a bag leak occurs, if the operator fails to close the corresponding bag dust collector in time, the dust-carrying gas will be discharged into the atmosphere, causing environmental pollution. The bag dust collector can be automatically controlled by PLC, which can effectively control the pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example 1

[0036] like Figures 1 to 3 As shown, Figure 2 A dust collector bag leakage rapid detection device comprises a bag dust collector and a detection component, wherein the bag dust collector comprises a clean air outlet pipe 1, the detection component is arranged on the bottom surface of the clean air outlet pipe 1 of the bag dust collector, and the clean air outlet pipe 1 is provided with a through hole for fixing the detection component.

[0037] The detection assembly includes a guide plate 2, a connecting tube 3 and a collecting bottle 4 which are connected in sequence from top to bottom. The guide plate 2 is located inside the clean gas outlet pipe 1. The guide plate 2 is U-shaped and bends toward the clean gas outlet. The connecting tube 3 is fixed at the through hole. The connection between the collecting bottle 4 and the connecting tube 3 is a detachable connection. In this embodiment, the connection between the collecting bottle 4 and the connecting tube 3 is a threaded connection.

[0038] The collecting bottle 4 is made of a transparent material. In this embodiment, the collecting bottle 4 is made of resin.

[0039] The connecting tube 3 has a smooth inner wall. The smooth inner wall can be controlled by the preparation material, such as using a resin material to prepare the connecting tube 3; or can be achieved by grinding after preparation.

[0040] In this embodiment, the height of the guide plate 2 is 1 / 3 of the inner height of the clean gas outlet pipe 1, and the width of the guide plate 2 is 1 / 10 of the inner width of the clean gas outlet pipe 1. The lower part of the guide plate 2 is closed.

[0041] When in use, a through hole is firstly opened on the bottom surface of the clean gas outlet pipe 1, and after the guide plate 2 and the connecting tube 3 are fixedly connected, the connecting tube 3 is fixed at the through hole, so that the guide plate 2 extends into the clean gas outlet pipe 1, and the connecting tube 3 and the collecting bottle 4 are connected by threads. When the bag inside the bag filter leaks, the dust particles carried in the air are disturbed and then settle, and the dust at the guide plate 2 enters the transparent collecting bottle 4 from the connecting tube 3, so that the operator can observe the leakage conveniently.

[0042] After the leakage is dealt with, the collecting bottle 4 is unscrewed for cleaning, and the inner wall of the connecting tube 3 and the guide plate 2 facing the clean air are also cleaned to ensure that the inside of the detection component is dust-free and does not affect the subsequent detection of leakage.

[0043] Example 2

[0044] A dust collector bag leakage rapid detection device, such as Figure 4 and Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the detection component further includes a spoiler baffle 5, and the spoiler baffle 5 is arranged upstream of the guide plate 2 relative to the direction of the clean air flow.

[0045] The spoiler baffles 5 include two spoiler baffles 5 symmetrically arranged with the guide plate 2 as the center, and the spoiler baffles 5 are fixed to the bottom surface of the inner wall of the clean air outlet pipe 1.

[0046] The width and height of the spoiler baffle 5 are the same as those of the guide plate 2 .

[0047] By arranging spoiler baffles 5 on both sides upstream of the guide plate 2, the clean air flowing through is first disturbed by the spoiler baffles 5, resulting in rotation in the direction of the guide plate 2. When bag leakage occurs, the dust carried in the clean air is gathered at the position of the guide plate 2. When the clean air flows through the guide plate 2, the dust can be settled more concentratedly, thereby improving the detection effect of the leakage.

[0048] The specific usage of the detection device provided in this embodiment is the same as that of Embodiment 1, except that, during cleaning, both sides of the spoiler baffle 5 need to be cleaned additionally to ensure that the subsequent detection of leakage is not affected.

[0049] Example 3

[0050] A dust collector bag leakage rapid detection device, such as Figure 6As shown, the difference between this embodiment and embodiment 2 is that the detection component also includes an alarm component, and the alarm component includes a dust concentration sensor 6, a PLC7 and an alarm 8. The dust concentration sensor 6 is located in the collection bottle 4, and the PLC7 is electrically connected to the dust concentration sensor 6 and the alarm 8 respectively. The PLC7 controls the alarm 8 to alarm according to the data measured by the dust concentration sensor 6.

[0051] By setting up the alarm component, the patrol burden of the operator is effectively reduced. When the alarm 8 sounds an alarm, the operator can handle the bag dust collector where the alarm detection component is located.

[0052] Further preferably, the PLC7 is also electrically connected to the bag dust collector, and the PLC7 controls the start and stop of the bag dust collector according to the data measured by the dust concentration sensor 6.

[0053] In specific use, when bag leakage occurs, if the operator fails to close the bag dust collector in time, the dust-carrying gas will be discharged into the atmosphere, causing environmental pollution. Automatic control of the bag dust collector by PLC7 can effectively control the pollution.
