Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a pulse filter cartridge dust collector. Background Technology

[0002] Pulse jet cartridge dust collectors are dust collectors that use cartridges as filter elements or employ pulse jet cleaning. They have advantages such as reasonable structure, high dust removal efficiency, and significant energy saving, and are widely used in dust and fume control in industries such as biopharmaceuticals, building materials, light industry, metallurgy, and chemicals. A typical pulse jet cartridge dust collector includes a support frame, a housing, a cleaning device, an inlet duct, and an outlet duct. The housing is mounted on top of the support frame, and the cleaning device is located inside the housing. The inlet and outlet ducts are located on opposite sides of the housing. Dust-laden gas enters through the inlet duct, is treated by the cleaning device, and is discharged through the outlet duct.

[0003] During operation, pulse jet dust collectors typically use timed pulse gas to clean the filter cartridges. However, this method has the following drawbacks: it cannot clean the dust in a timely manner, and the cleaning process is delayed. When timed cleaning is performed, the dust on the filter cartridges has often reached the cleaning condition for a long time. Therefore, before cleaning, the filtration efficiency of the filter cartridges is greatly reduced, affecting the dust removal effect. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pulse filter cartridge dust collector. By setting a detection component, the dust accumulation of the filter cartridge can be detected in real time, and the filter cartridge can be cleaned in time when the dust accumulation reaches the cleaning condition.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] See Figures 1-4 This utility model provides a technical solution: Example: like Figures 1-4 As shown, a pulse jet filter cartridge dust collector includes a dust collector body 1. The dust collector body 1 is provided with a dust collection chamber 2 and a clean air chamber 3 communicating with the dust collection chamber 2. A filter cartridge 4 is provided in the dust collection chamber 2. The dust collector body 1 is provided with an air inlet pipe communicating with the dust collection chamber 2 and an air outlet pipe communicating with the clean air chamber 3. The dust collection chamber 2 is connected to the clean air chamber 3 through the filter cartridge 4. A detection component for detecting the air pressure inside the dust collection chamber 2 is provided in the dust collection chamber 2. like Figure 4 As shown, the detection assembly includes a detection tube 5, a sealing element 6, and a sensor 7. The detection tube 5 is connected to the clean air chamber 3 and the dust removal chamber 2 respectively. The sealing element 6 is slidably disposed in the detection tube 5 and is used to seal the detection tube 5 before the air pressure in the dust removal chamber 2 reaches a preset value. When the air pressure in the dust removal chamber 2 rises to the preset value, the gas in the dust removal chamber 2 pushes the sealing element 6 to move towards the dust removal chamber 2, and the dust removal chamber 2 is connected to the clean air chamber 3 through the sealing element 6. The sensor 7 is installed inside the detection tube 5 and is located on the side of the sealing member 6 away from the dust removal chamber 2. The sensor 7 is used for airflow detection inside the detection tube 5.

[0018] The sealing element 6 is a cylindrical structure adapted to the inner diameter of the detection tube 5. The sealing element 6 is provided with an L-shaped gas communication channel 8. The first end of the gas communication channel 8 is connected to the end face of the sealing element 6 near the clean air chamber 3, and the second end of the gas communication channel is connected to the circumferential surface of the sealing element 6. The detection tube 5 is provided with a connecting hole 9. When the sealing member 6 moves to the second end of the gas communication channel and corresponds to the connecting hole 9, the dust removal chamber 2 and the clean air chamber 3 are connected.

[0019] The end of the sealing member 6 away from the clean air chamber 3 is provided with an elastic reset member 10 (which is a spring).

[0020] A retaining ring 11 is coaxially fixed at one end of the detection tube 5 away from the clean air chamber 3. A retaining block 12 is also fixed inside the detection tube 5. The sensor 7 is mounted on the retaining block 12. The retaining block 12 is mounted on the side of the sealing member 6 near the clean air chamber 3. The retaining block 12 is used for positioning the sealing member 6.

[0021] The lower end of the dust removal chamber 2 has a funnel-shaped structure, and the lower end of the dust removal chamber 2 is connected to the dust collection bucket 13 through a flange.

[0022] 1. The pulse filter cartridge 4 dust collector body 1 is existing technology, and its specific structure and working principle will not be described in detail here. 2. The sensor 7 is used to detect the presence of airflow by detecting the gas velocity. When the gas velocity is greater than 0 or a preset value, it can be determined that gas is passing through the detection tube 5. The specific model selection and working principle of the sensor 7 are existing technology and will not be described in detail here. 3. The sensor 7 can be electrically connected to the PLC controller of the dust collector body 1 for signal transmission. 4. Filter cotton is installed at the rear end of the baffle 12 to filter the small amount of gas entering the dust collection chamber 2.

[0023] Working principle: During normal dust removal, dust accumulates on filter cartridge 4. When the dust accumulates to a certain level, the filtration efficiency of filter cartridge 4 decreases, the resistance to gas increases, and consequently the air pressure inside dust removal chamber 2 increases.

[0024] When the air pressure inside the dust removal chamber 2 increases, the gas pushes the sealing component 6 toward the clean air chamber 3. This process overcomes the spring force until the sealing component 6 moves to contact the stop block 12. At this time, the gas communication channel corresponds to and is connected with the communication hole 9. The dust removal chamber 2 is connected to the clean air chamber 3 through the communication hole 9, the gas communication channel, and the detection tube 5.

[0025] The gas in the dust removal chamber 2 enters the clean air chamber 3 through the through hole, gas communication channel 8, and detection tube 5. The sensor 7 detects that the gas flow rate increases from zero or from a certain constant flow rate to a preset value, and then transmits the signal to the PLC controller. The PLC controller can then immediately control the pulse gas to clean the dust from the filter cartridge 4.

[0026] After the gas on filter cartridge 4 is cleaned, the filtering capacity of filter cartridge 4 is restored, the air pressure in dust removal chamber 2 drops, and at this time the sealing part 6 is reset under the action of the spring. Dust removal chamber 2 is no longer connected to clean air chamber 3 through detection tube 5, and the gas flow rate detected by sensor 7 returns to zero, preparing for the next dust removal of filter cartridge 4.

[0027] This invention can detect the dust accumulation on the filter cartridge in real time by setting up a detection component, and can clean the filter cartridge in a timely manner when the dust accumulation reaches the cleaning condition.

[0028] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
