Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and dust removal, in particular to an intelligent terminal valve for ventilation and dust removal. Background Art

[0002] Ventilation and dust removal devices are widely used in various occasions where air quality needs to be controlled, such as industrial production environments such as steel and cement. These industries will generate a lot of dust and pollutants during the production process, so ventilation and dust removal devices are needed to ensure the cleanliness of the production environment and the health of employees. In addition, ventilation and dust removal devices are also commonly used in commercial buildings, hospitals, schools and other public places to provide people with a comfortable and healthy indoor environment;

[0003] Usually, dust removal devices usually need to use pulse back-blowing dust collectors. Its working principle is to set a pulse blowing device on the filter bag of the dust collector. Through the high-pressure gas injection, the surface of the filter bag generates a pressure wave of expansion and contraction, which shakes off the dust accumulated on the surface of the filter bag, thereby achieving the effect of cleaning. The specific process is: after the dust collector has been working for a period of time, a certain amount of dust has accumulated on the surface of the filter bag. At this time, the pulse back-blowing controller will send a signal to guide the high-pressure gas of the pulse blowing device into the blowing pipe above the filter bag. The high-pressure gas passes through the blowing pipe to the blowing solenoid valve. After the solenoid valve is activated, the high-pressure gas is rapidly released in a very short time, forming a pressure wave, which shakes off the dust on the surface of the filter bag;

[0004] For example, in the prior art, a Chinese patent with a patent publication number of CN219482025U discloses a pulse back-blowing cleaning filter cartridge dust collector for silo ventilation and dust removal. While performing pulse back-blowing, the device uses the cover plate of the sealing mechanism to move downward to seal the exhaust hole, thereby avoiding the pressure loss caused by the back-blowing airflow flowing out of the exhaust hole, and ultimately improving the back-blowing cleaning effect;

[0005] However, the sealing mechanism of the device cannot be combined with the pulse valve, which increases the cost, and the cover of the device is set above the exhaust hole. When the cover is not covering the exhaust hole, the air flowing upward from the exhaust hole can only flow from the four sides of the cover, which affects the fluidity of the air and reduces the ventilation and dust removal effect. Therefore, an intelligent terminal valve for ventilation and dust removal is designed to solve the above problems. Utility Model Content

[0029] Example:

[0030] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides an intelligent terminal valve for ventilation and dust removal, including a ventilation and dust removal box 1, an air intake pipe 2, a dust collecting hopper 3, a filter element 4, an exhaust hopper 5 and a fan 6. The air intake pipe 2 is provided through the lower side of the ventilation and dust removal box 1, the dust collecting hopper 3 is fixedly provided at the bottom of the ventilation and dust removal box 1, the filter element 4 is installed in the center of the ventilation and dust removal box 1, the exhaust hopper 5 is fixedly provided on the top of the inner side of the ventilation and dust removal box 1, the fan 6 is fixedly provided on the top of the inner side of the exhaust hopper 5, the pulse tube 7 is provided through the top of the left side of the ventilation and dust removal box 1, and the pulse valve 8 is provided through the bottom of the pulse tube 7;

[0031] The exhaust scoop 5 includes a rotating shaft 501, a baffle plate 502 and a gear 503. The baffle plates 502 are rotatably arranged on both sides of the exhaust scoop 5. A gear 503 is fixedly arranged at the end of the left rotating shaft 501. When the pulse valve 8 is opened and closed, the gear 503 can be driven to rotate.

[0032] During ventilation and dust removal, the fan 6 is turned on to blow the gas in the ventilation and dust removal box 1 upwards, and the air enters the ventilation and dust removal box 1 through the air inlet pipe 2. The dust in the air is filtered by the filter element 4 in the ventilation and dust removal box 1 to achieve the dust removal effect. When there is too much dust on the filter element 4, the pulse valve 8 is opened, and the high-pressure gas back-blows the filter element 4. The dust on the filter element 4 falls into the dust collecting hopper 3 for collection, thereby achieving the effect of ventilation and dust removal.

[0033] In this embodiment, the diameter of the shielding plate 502 is equal to the inner diameter of the exhaust scoop 5, so that the shielding plate 502 can completely block the exhaust scoop 5 when it is in a horizontal state.

[0034] In this embodiment, the pulse valve 8 includes a cross bar 801, a valve stem 802, a fixed disk 803, a sleeve spring 804, a valve seat 805, a valve plate 806 and a rack 807. The cross bar 801 is fixedly provided on the inner top of the pulse valve 8, the valve stem 802 is penetrated through the cross bar 801, the fixed disk 803 is fixedly provided on the top of the valve stem 802, the sleeve spring 804 is fixedly provided between the fixed disk 803 and the cross bar 801, the valve seat 805 is fixedly provided on the inner lower part of the pulse valve 8, the valve plate 806 is fixedly provided at the bottom of the valve stem 802, and the rack 807 is fixedly provided at the bottom of the valve plate 806.

[0035] In this embodiment, the valve seat 805 is disc-shaped, the valve plate 806 is disc-shaped, and the diameter of the valve plate 806 is larger than the diameter of the central through hole of the valve seat 805 .

[0036] In this embodiment, when the sleeve spring 804 is in a naturally extended state, the valve plate 806 is tightly attached to the upper surface of the valve seat 805 , ensuring that the valve plate 806 seals the central through hole on the valve seat 805 .

[0037] In this embodiment, the valve seat 805 and the valve plate 806 are both made of electromagnetic materials, and after the valve seat 805 and the valve plate 806 are charged, the contact surfaces of the valve seat 805 and the valve plate 806 are both N poles or S poles. After the pulse valve 8 is powered on, the valve seat 805 and the valve plate 806 generate magnetism, and the same poles repel each other, so that the valve plate 806 and the valve seat 805 are separated, thereby achieving the effect of opening the pulse valve 8.

[0038] In this embodiment, the rack 807 is meshed with the gear 503, and when the valve plate 806 of the pulse valve 8 is in contact with the valve seat 805, the baffle 502 is vertical. At this time, the pulse valve 8 is in a closed state, and the vertical shape of the baffle 502 will not affect normal exhaust.

[0039] In this embodiment, when the pulse valve 8 is opened, the distance moved by the valve plate 806 is equal to 1 / 4 of the circumference of the gear 503. When the pulse valve 8 is opened, the valve plate 806 moves upward, and the rack 807 at the bottom of the valve plate 806 moves upward. The rack 807 drives the gear 503 to rotate 90°, so that the baffle plate 502 is horizontal, shielding the exhaust scoop 5 to prevent gas from being discharged from the exhaust scoop 5 during backblowing.

[0040] In this embodiment, the pulse tube 7 is connected to an external high-pressure gas source, and the high-pressure gas source provides a gas source for the pulse tube 7 .

[0041] By providing a pulse valve 8, when the pulse valve 8 is powered on, the valve seat 805 and the valve plate 806 are charged to generate magnetism, and the contact surfaces of the valve seat 805 and the valve plate 806 are of the same polarity, and the same polarities repel each other, so that the valve plate 806 moves upward, and the valve seat 805 and the valve plate 806 are separated, so that it is convenient for high-pressure gas to enter the ventilation and dust removal box 1 from the pulse tube 7, and the valve plate 806 moves upward to drive the rack 807 to move upward, and the rack 807 drives the gear 503 to rotate 90°, and the gear 503 drives the shielding plate 502 to rotate 90° through the rotating shaft 501, so that the shielding plate 502 is in a horizontal state, shielding Plate 502 blocks the exhaust scoop 5 to prevent high-pressure gas from being discharged from the exhaust scoop 5, ensuring that all high-pressure gas passes through the filter element 4, ensuring the cleaning effect when backblowing the filter element 4. After the pulse ends, the pulse valve 8 is closed, and the elastic force of the sleeve spring 804 causes the valve plate 806 and the rack 807 to move downward, driving the gear 503 to rotate 90°, so that the baffle plate 502 is in a vertical state. The baffle plate 502 will not affect the normal exhaust of the exhaust scoop 5. The exhaust scoop 5 is shielded by changing the angle of the baffle plate 502 in the exhaust scoop 5, thereby reducing the impact on the normal exhaust of the exhaust scoop 5.

[0042] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
