Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to a cyclone cartridge filter combined dust collector. Background Technology

[0002] Generally, cyclone dust collectors separate large dust particles through centrifugal force, while cartridge dust collectors filter fine particles through filter media. Combining the two should improve overall dust removal efficiency, and is therefore widely used in scenarios requiring high dust removal efficiency, such as grain storage dust collection. Existing technologies, such as the high-efficiency combined dust collection system disclosed in CN208553586U and the combined cleaning unit disclosed in CN205146477U, are examples of relatively conventional cyclone-cartridge combined dust collector solutions based on the aforementioned mechanism. However, conventional cyclone-cartridge combined dust collectors still need to consider the individual problems of each type of dust collector, as well as the issues arising from their synergy. New problems have emerged, such as high system resistance in combined dust collectors, more prone filter cartridge clogging, and insufficient intelligent control. The high system resistance is due to the combined resistance of the cyclone section and the filter cartridge section. To ensure the ventilation effect of the system, especially to meet the air pressure requirements of cyclone dust removal, it is necessary to increase the power consumption of the fan. This is particularly true for large-scale scenarios such as grain storage dust removal, where the fan needs to continuously output high power. Therefore, ensuring efficient cooling and heat dissipation of the fan is a problem. At the same time, when the filter cartridges of the cartridge dust collector are exposed to high humidity airflow, fine particles such as dust are easily caked on the surface of the filter cartridges, thus clogging them. Even with a pulse cleaning system, the effect is still not very good, thus increasing maintenance time and costs. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a cyclone cartridge dust collector to solve the problem that it is difficult to ensure efficient heat dissipation of the fan unit and further reduce the caking and blockage of the filter cartridge surface in existing cyclone cartridge dust collectors.

[0004] To achieve the above objectives, the present invention provides a cyclone cartridge filter combined dust collector, comprising a cyclone dust collector and a pulse-jet cartridge filter connected in series, and a fan unit for exhaust ventilation.

[0005] The pulse-jet cartridge dust collector is located on the adjacent side of the cyclone dust collector;

[0006] The top of the cyclone dust collector is connected to an air inlet on one side. An exhaust pipe runs through the cyclone dust collector. The top of the exhaust pipe passes through the cyclone dust collector and is connected to an exhaust duct. The exhaust duct is connected to the air inlet of the pulse-jet cartridge dust collector. The pulse-jet cartridge dust collector has an air outlet on the side away from the cyclone dust collector.

[0007] The fan unit is equipped with cooling pipes, which include heat exchange sections arranged along the cylinder of the cyclone dust collector. The heat exchange sections include, in sequence, a transverse liquid inlet section arranged along the inner top wall of one side of the cylinder, a vertical liquid inlet section arranged along the side wall of one side of the exhaust pipe, a transverse heat exchange section passing through the bottom of the exhaust pipe, a vertical liquid outlet section arranged along the side wall of the other side of the exhaust pipe, and a transverse liquid outlet section arranged along the inner top wall of the other side of the cylinder. Working fluid circulates in the cooling pipes for heat exchange with the incoming air.

[0008] A self-cleaning component is attached to the transverse heat exchange section. A movable cylinder is located at the bottom center of the exhaust pipe. One end of the movable cylinder is connected to the self-cleaning component. As the exhaust air pressure fluctuates, the movable cylinder is driven to extend and retract, and the self-cleaning component is driven to slide back and forth along the transverse heat exchange section to clean the dust accumulated on the transverse heat exchange section.

[0009] Preferably, the transverse heat exchange section is provided in multiple sections along the radial direction inside the exhaust pipe.

[0010] Preferably, a support column is erected in the middle of the exhaust pipe, a transverse heat exchange section is transversely passed through and fixed on the support column, a bottom groove is opened at the bottom end of the support column, the top end of the movable cylinder passes through the bottom groove and is slidably connected with the bottom groove, and an elastic element is connected between the top end of the movable cylinder and the inner top wall of the bottom groove.

[0011] Preferably, the bottom end of the movable cylinder is connected to a wind baffle plate, and the horizontal outer diameter of the wind baffle plate is larger than the horizontal outer diameter of the support column.

[0012] Preferably, the self-cleaning component includes a rigid mesh covering the outside of the transverse heat exchange section. One end of the rigid mesh near the support column is connected to a connecting rope, and the other end away from the support column is connected to the transverse heat exchange section by an elastic mesh belt. One end of the connecting rope passes through the bottom groove and is connected to the top of the movable cylinder.

[0013] Preferably, a heating tube is provided on the support column above the transverse heat exchange section, and multiple sets of heating tubes are arranged at intervals from top to bottom. A humidity sensor is provided inside the cylinder of the cyclone dust collector. When the humidity sensor detects an increase in humidity inside the cylinder, it triggers the heating of the corresponding set of heating tubes.

[0014] Preferably, a sliding sleeve is fitted onto the support column, one end of the heating tube is connected to the outside of the sliding sleeve, a lifting part is provided inside the support column, a crossbar is connected to the top of the lifting part, and the end of the crossbar extends outward through the support column and is fixedly connected to the inside of the sliding sleeve.

[0015] Preferably, the outer ring of the sliding sleeve is rotatably connected to a movable sleeve, one end of the heating tube is fixedly connected to the outside of the movable sleeve, and a positioning groove is provided on the inner side wall of the exhaust pipe. The outer end of the heating tube slides along the trajectory of the positioning groove. When all the lifting parts are in the retracted state, each heating tube and the transverse heat exchange section are located in the same radial position inside the exhaust pipe. When the heating tube is driven to rise by the lifting parts, the heating tube is placed in a different radial position from the transverse heat exchange section.

[0016] Preferably, each heating tube is fitted with a tube cleaning component. The end of the tube cleaning component near the support column is connected to a separate rope. The bottom end of the separate rope passes through the bottom groove and is connected to the top of the movable cylinder. When the heating tube is driven to rise by the lifting part, the corresponding separate rope is tensioned, which is used to drive the tube cleaning component to slide back and forth along the heating tube.

[0017] The beneficial effects of this invention are as follows: The fan unit is equipped with cooling pipes, which include heat exchange sections arranged along the cylinder of the cyclone dust collector. These heat exchange sections sequentially include a transverse liquid inlet section arranged along the inner top wall of one side of the cylinder, a vertical liquid inlet section arranged along the side wall of one side of the exhaust pipe, a transverse heat exchange section extending through the bottom of the exhaust pipe, a vertical liquid outlet section arranged along the side wall of the other side of the exhaust pipe, and a transverse liquid outlet section arranged along the inner top wall of the other side of the cylinder. Self-cleaning components are attached to the transverse heat exchange sections, which, in response to fluctuations in the exhaust air pressure within the exhaust pipe, provide cooling. The movable cylinder extends and retracts, driving the self-cleaning component to slide back and forth along the transverse heat exchange section. This self-cleaning action, combined with pulse jet cleaning, prevents the heat exchange efficiency from being affected by excessive dust accumulation. When the working fluid, after absorbing heat, flows through the heat exchange section, it exchanges heat with the ambient or cooler inlet air, which helps to cool the working fluid. At the same time, the transverse heat exchange section heats the inlet air, which helps to reduce the humidity of the inlet air and further prevents the filter cartridge surface from hardening and clogging the filter cartridge, achieving a two-way beneficial effect.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cyclone cartridge dust collector includes a cyclone dust collector 100 and a pulse-jet cartridge dust collector 200 connected in series, and a fan unit for exhaust. The pulse-jet cartridge dust collector 200 is located on an adjacent side of the cyclone dust collector 100. An air inlet 102 is connected to one side of the top of the cylinder 101 of the cyclone dust collector 100. An exhaust pipe 103 is installed through the cylinder 101 of the cyclone dust collector 100, and the top of the exhaust pipe 103 extends out of the cyclone dust collector 100 and is connected to an exhaust duct 1. The exhaust duct 1 is connected to the air inlet of the pulse-jet cartridge dust collector 200. An air outlet 2 is provided on the side of the pulse-jet cartridge dust collector 200 away from the cyclone dust collector 100. The fan unit is equipped with a cooling pipe 3, which includes a heat exchange section arranged along the inside of the cylinder 101 of the cyclone dust collector 100. The heat exchange section includes, in sequence, a transverse liquid inlet section 31 arranged along the inner top wall of one side of the cylinder 101, a vertical liquid inlet section 32 arranged along the side wall of one side of the exhaust pipe 103, a transverse heat exchange section 33 passing through the inner bottom end of the exhaust pipe 103, a vertical liquid outlet section 34 arranged along the side wall of the other side of the exhaust pipe 103, and a transverse liquid outlet section 35 arranged along the inner top wall of the other side of the cylinder 101. Working fluid circulates in the cooling pipe 3 for heat exchange with the incoming air. A self-cleaning component 4 is attached to the transverse heat exchange section 33. A movable cylinder 5 is provided at the middle of the bottom end of the exhaust pipe 103. One end of the movable cylinder 5 is connected to the self-cleaning component 4. With the fluctuation of the exhaust air pressure in the exhaust pipe 103, the movable cylinder 5 is driven to extend and retract, and the self-cleaning component 4 is driven to slide back and forth along the transverse heat exchange section 33 for self-cleaning the dust accumulated on the transverse heat exchange section 33.

[0034] This invention is based on the basic structure of cyclone dust collectors and pulse-jet cartridge dust collectors. Specifically, it includes a cyclone dust collector 100 and a pulse-jet cartridge dust collector 200 connected in series, and a fan unit for exhaust. The pulse-jet cartridge dust collector 200 is located adjacent to the cyclone dust collector 100. An air inlet 102 is connected to one side of the top of the cylindrical body 101 of the cyclone dust collector 100. An exhaust pipe 103 passes through the cylindrical body 101 of the cyclone dust collector 100, and its top end extends out of the cyclone dust collector 100 and is connected to an exhaust duct 1. The exhaust duct 1 is connected to the air inlet of the pulse-jet cartridge dust collector 200. An air outlet 2 is located on the side of the pulse-jet cartridge dust collector 200 away from the cyclone dust collector 100. Generally, the fan unit can be connected to one end of the air outlet 2 to provide negative pressure suction. Air enters the cylinder 101 through the inlet 102, then spirals down the inner wall of the cylinder 101, and finally exits upward through the middle of the cylinder 101 until it passes through the exhaust pipe 103 and is connected to the pulse-jet cartridge dust collector 200 through the exhaust pipe 1. The pulse-jet cartridge dust collector 200 is equipped with multiple sets of filter cartridges. The incoming air passes through the filter cartridges to further filter out fine dust particles, and finally exits through the outlet 2. The pulse-jet cartridge dust collector 200 is equipped with multiple pulse valves 201, which are used to intermittently blow clean air toward the filter cartridges and to back-flush and remove the dust and other fine particles accumulated on the filter cartridges. The dust and other fine particles move down along the cone at the bottom of the dust collector and are collected by the ash hopper. The bottom of the cyclone cartridge dust collector can also be equipped with an ash conveyor 6, which is used to periodically clean the dust and impurities in the ash hopper.

[0035] The fan unit is equipped with a cooling pipe 3, which includes a heat exchange section arranged along the cylinder 101 of the cyclone dust collector 100, such as... Figure 2As shown, the heat exchange section sequentially includes a transverse liquid inlet section 31 arranged along the inner top wall of one side of the cylinder 101, a vertical liquid inlet section 32 arranged along the side wall of one side of the exhaust pipe 103, a transverse heat exchange section 33 passing through the inner bottom end of the exhaust pipe 103, a vertical liquid outlet section 34 arranged along the side wall of the other side of the exhaust pipe 103, and a transverse liquid outlet section 35 arranged along the inner top wall of the other side of the cylinder 101. Working fluid circulates in the cooling pipe 3 for heat exchange with the incoming air. A self-cleaning component 4 is attached to the transverse heat exchange section 33. A movable cylinder 5 is provided in the middle of the bottom end of the exhaust pipe 103. One end of the movable cylinder 5 is connected to the self-cleaning component 4. Considering that the exhaust air pressure in the exhaust pipe 103 will inevitably fluctuate, especially when connected to the pulse-type cartridge dust collector 200, due to the pulse valve 20 1. Controlling periodic blowing will also cause fluctuations in the air pressure inside the equipment. As the air pressure in the exhaust pipe 103 fluctuates, it drives the movable cylinder 5 to extend and retract, and drives the self-cleaning component 4 to slide back and forth along the transverse heat exchange section 33. This is used to self-clean the dust accumulated on the transverse heat exchange section 33. The self-cleaning effect achieved by combining pulse blowing avoids the heat exchange effect of the transverse heat exchange section 33 being affected by excessive dust accumulation. When the working fluid in the cooling pipe 3 flows through the fan unit, it is used to absorb heat and cool the fan unit. After absorbing heat, the working fluid flows through the heat exchange section and exchanges heat with the normal temperature or colder inlet air, which is beneficial for cooling the working fluid. At the same time, the transverse heat exchange section 33 heats the inlet air, which is beneficial for reducing the humidity of the inlet air and further preventing the filter cartridge surface from hardening and clogging the filter cartridge, achieving a two-way beneficial effect.

[0036] In an embodiment of the present invention, optionally, the transverse heat exchange section 33 is provided with multiple sections along the inner radial direction of the exhaust pipe 103, for example... Figure 5 As shown, the transverse heat exchange section 33 is arranged in three sections along the inner radial direction of the exhaust pipe 103. One section is connected to the bottom end of the vertical liquid inlet section 32, and the remaining two sections are connected to the bottom end of the vertical liquid outlet section 34. This is equivalent to the liquid inlet branching into two streams at the transverse heat exchange section 33 and then exiting the liquid outlet section 34, which helps to further improve the heat exchange efficiency.

[0037] Specifically, the vertical liquid inlet section 32 and the vertical liquid outlet section 34 can be attached to or embedded on the outer wall of the exhaust pipe 103, and the horizontal liquid inlet section 31 and the horizontal liquid outlet section 35 can similarly be attached to or embedded on the inner top wall of the cylinder 101, thereby facilitating further heat exchange with the incoming air.

[0038] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4As shown, a support column 7 is erected in the middle of the exhaust pipe 103. The transverse heat exchange section 33 is transversely passed through and fixed on the support column 7. A bottom groove 71 is opened at the bottom end of the support column 7. The top end of the movable cylinder 5 passes through the bottom groove 71 and is slidably connected with the bottom groove 71. An elastic element 8 is connected between the top end of the movable cylinder 5 and the inner top wall of the bottom groove 71. The elastic element 8 can be a conventional elastic component such as a spring, so that the movable cylinder 5 can move up and down elastically with the fluctuation of the exhaust air pressure in the exhaust pipe 103.

[0039] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4 As shown, the bottom end of the movable cylinder 5 is connected to a baffle plate 9. The horizontal outer diameter of the baffle plate 9 is larger than the horizontal outer diameter of the support column 7, thereby further increasing the contact air intake area, which is conducive to driving the movable cylinder 5 to move up and down elastically, and at the same time, it is conducive to further preventing dust accumulation in the middle of the transverse heat exchange section 33 and on the support column 7.

[0040] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the self-cleaning component 4 includes a rigid mesh 41 covering the outside of the transverse heat exchange section 33. The rigid mesh 41 can be made of a metal material with good thermal conductivity, which is not easy to break or deform and does not affect the heat exchange efficiency of the transverse heat exchange section 33. One end of the rigid mesh 41 near the support column 7 is connected to a connecting rope 42, and the other end away from the support column 7 is connected to an elastic mesh belt 43 between it and the transverse heat exchange section 33. One end of the connecting rope 42 passes through the bottom groove 71 and is connected to the top of the movable cylinder 5. The rigid mesh 41 is set in a mesh structure, and the movable cylinder 5 moves up and down elastically, driving the connecting rope 42 to pull the rigid mesh 41 to slide back and forth along the length of the outer side of the transverse heat exchange section 33, thereby achieving the function of cleaning the dust accumulated on the outside of the transverse heat exchange section 33. The loosened dust flows into the pulse filter cartridge dust collector 200 with the exhaust air and is treated.

[0041] Optionally, the rigid mesh 41 may also be a spiral structure along the length of the outer side of the transverse heat exchange section 33.

[0042] In embodiments of the present invention, optionally, such as Figure 2As shown, a heating tube 10 is provided on the support column 7 above the transverse heat exchange section 33. Multiple sets of heating tubes 10 are arranged at intervals from top to bottom. A humidity sensor is provided inside the cylinder 101 of the cyclone dust collector 100. When the humidity sensor detects an increase in humidity inside the cylinder 101, it triggers the corresponding set of heating tubes 10 to heat up. For example, if the humidity is detected to rise to a first preset value, the first set of heating tubes 10 near the transverse heat exchange section 33 is triggered to start heating. If the humidity is detected to rise to a second preset value, the first set of heating tubes 10 and the second set of heating tubes 10 near the first set of heating tubes 10 are triggered to start heating simultaneously. And so on. When the heat exchange of the transverse heat exchange section 33 is insufficient to reduce the humidity to above the first preset value, the corresponding heating tubes 10 are triggered to assist in heating to maintain a stable humidity requirement. The heat of the heating tubes 10 is carried away by the upward airflow, which has a limited impact on the transverse heat exchange section 33 arranged at intervals below.

[0043] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a sliding sleeve 11 is fitted onto the support column 7. One end of the heating tube 10 is connected to the outside of the sliding sleeve 11. A lifting part 12 is provided inside the support column 7. A crossbar 13 is connected to the top of the lifting part 12. The end of the crossbar 13 extends outward through the support column 7 and is fixedly connected to the inside of the sliding sleeve 11. The lifting part 12 can be a conventional component such as a lifting cylinder. The lifting cylinder is electrically connected to the humidity sensor, thereby driving the crossbar 13, the sliding sleeve 11 and the corresponding heating tube 10 to rise and fall.

[0044] Among them, the outer side of the support column 7 is provided with a groove 72 for the crossbar 13 to pass through and move up and down. The horizontal outer diameter of the wind baffle 9 is larger than the horizontal outer diameter of the support column 7, which also helps to prevent dust from accumulating along the groove 72 when the air enters.

[0045] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the outer ring of the sliding sleeve 11 is rotatably connected to the movable sleeve 14, and one end of the heating tube 10 is fixedly connected to the outside of the movable sleeve 14, so that the heating tube 10 assembly can rotate axially along the outer ring of the sliding sleeve 11. A positioning groove 104 is provided on the inner side wall of the exhaust pipe 103, and the outer end of the heating tube 10 slides along the trajectory of the positioning groove 104. When the lifting part 12 is fully retracted, as... Figure 5 , Figure 8As shown, each heating tube 10 and the transverse heat exchange section 33 are located in the same radial orientation within the exhaust pipe 103, which helps to prevent dust accumulation on each heating tube 10. When the lifting part 12 extends upward, it drives the sliding sleeve 11 and the movable sleeve 14 to rise synchronously. Since the outer end of the heating tube 10 slides along the trajectory of the positioning groove 104, the arc-shaped design at the top of the positioning groove 104 drives the heating tube 10 group and the movable sleeve 14 to rotate axially. Figure 6 , Figure 9 , Figure 10 As shown, the heating tube 10 is positioned in a different radial orientation than the transverse heat exchange section 33, thereby improving the heat exchange efficiency of the heating tube 10.

[0046] In embodiments of the present invention, optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, each heating tube 10 is fitted with a tube cleaning component 15. One end of the tube cleaning component 15 near the support column 7 is connected to a separate rope 16. The bottom end of the separate rope 16 penetrates into the bottom groove 71 and is connected to the top of the movable cylinder 5. The tube cleaning component 15 and the separate rope 16 adopt a similar structural design to the self-cleaning component 4 and the connecting rope 42. However, when the lifting part 12 is in the retracted state, the corresponding separate rope 16 is in the relaxed state and will not drive the tube cleaning component 15 to move, thereby avoiding redundant transmission movement. When the lifting part 12 drives the heating tube 10 to rise, the corresponding separate rope 16 is tensioned to drive the tube cleaning component 15 to slide back and forth along the heating tube 10, achieving the same cleaning and dust removal effect.

[0047] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
