Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a cyclone filter cartridge type combined dust collector. Background Art

[0002] Generally, cyclone dust collectors separate large dust particles through centrifugal force, while cartridge dust collectors filter fine particles through filter materials. The combination of the two should be able to improve the overall dust removal efficiency. Therefore, they are widely used in existing scenarios with higher dust removal efficiency, such as grain storage dust removal. The prior art, such as a high-efficiency combined dust removal system disclosed in CN208553586U and a combined cleaning and blowing unit disclosed in CN205146477U, are also examples of relatively conventional cyclone cartridge combined dust removal equipment based on the above mechanism. However, conventional cyclone cartridge combined dust removal equipment still needs to consider the problems existing in the two dust collectors respectively, as well as the problems generated by their mutual cooperation. New problems, for example, the combined dust collector system has high resistance, the filter cartridge is more easily clogged, and the intelligent control is insufficient. The high system resistance is due to the superposition of the resistances of the cyclone part and the filter cartridge part. In order to ensure the ventilation effect of the system, especially to meet the wind pressure requirements of cyclone dust removal, it is necessary to increase the power consumption of the fan. Especially for large-scale scenes such as grain storage dust removal, the fan needs to have continuous high power output. Therefore, there is a problem of how to ensure the efficient cooling and heat dissipation of the fan. At the same time, when the filter cartridge of the filter cartridge dust collector faces high-humidity air intake, fine particles such as dust are easy to compact on the surface of the filter cartridge and thus clog the filter cartridge. Even if a pulse cleaning system is used, it still cannot achieve a good effect, thereby increasing maintenance time and cost. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose a cyclone filter cartridge type combined dust collector to solve the problem that it is difficult to ensure efficient heat dissipation of the fan unit and further reduce the problem of compaction and blockage on the filter cartridge surface in existing cyclone filter cartridge type combined dust removal equipment.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cyclone filter cartridge type combined dust collector comprises a cyclone dust collector 100 and a pulse filter cartridge dust collector 200 connected in series, and a fan unit for exhausting air, wherein the pulse filter cartridge dust collector 200 is arranged on an adjacent side of the cyclone dust collector 100, and an air inlet 102 is connected to one side of the top end of the cylinder 101 of the cyclone dust collector 100, an exhaust pipe 103 is penetrated through the cylinder 101 of the cyclone dust collector 100, and the top end of the exhaust pipe 103 penetrates through 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 filter cartridge dust collector 200, an air outlet 2 is arranged on the side of the pulse filter cartridge dust collector 200 away from the cyclone dust collector 100, a cooling duct 3 is arranged on the fan unit, and the cooling duct 3 comprises a heat exchange section arranged along 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 in the middle of the bottom end of the exhaust pipe 103. One end of the movable cylinder 5 is transmission-connected with 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, so as to self-clean the dust accumulated on the transverse heat exchange section 33.

[0020] The present invention is based on the basic remote structure of a cyclone dust collector and a pulse filter cartridge dust collector, and specifically includes a cyclone dust collector 100 and a pulse filter cartridge dust collector 200 connected in series, and a fan unit for exhausting air. The pulse filter cartridge dust collector 200 is arranged on an adjacent side of the cyclone dust collector 100, and an air inlet 102 is connected to one side of the top end of the cylinder 101 of the cyclone dust collector 100. An exhaust pipe 103 is penetrated through the cylinder 101 of the cyclone dust collector 100, and the top end of the exhaust pipe 103 penetrates 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 filter cartridge dust collector 200. An air outlet 2 is provided on the side of the pulse filter 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 a negative pressure suction action. The air intake enters the cylinder 101 along the air inlet 102, then sinks in a spiral cyclone-like manner along the inner wall of the cylinder 101, and then is discharged upward along the middle part of the cylinder 101 until it passes through the exhaust pipe 103, and is led to the pulse filter cartridge dust collector 200 through the exhaust duct 1. The pulse filter cartridge dust collector 200 is provided with multiple groups of filter cartridges. The air intake passes through the filter cartridges to further filter out fine dust particles, and finally is discharged from the air outlet 2. Among them, the pulse filter cartridge dust collector 200 is provided with multiple pulse valves 201, which are used to intermittently spray clean air toward the filter cartridges and to back-blow to remove fine particles such as dust accumulated on the filter cartridges. Fine particles such as dust move down along the cone at the bottom of the dust collector and are collected by the ash hopper. The bottom end of the cyclone filter cartridge combination dust collector may also be provided with an ash conveyor 6, which is used to regularly clean and collect dust and impurities in the ash hopper.

[0021] A cooling pipe 3 is provided on the fan unit, and the cooling pipe 3 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 includes in sequence a horizontal 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 horizontal 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 horizontal 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 member 4 is attached to the horizontal 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 transmission-connected to the self-cleaning member 4. Considering that the exhaust air pressure in the exhaust pipe 103 will inevitably fluctuate, especially when the pulse filter cartridge dust collector 200 is connected in series, due to the pulse valve 20 1 Controlling the periodic blowing will also cause the wind pressure fluctuation in the equipment, thereby driving the movable cylinder 5 to telescopic movement with the fluctuation of the exhaust air pressure in the exhaust pipe 103, and driving the self-cleaning member 4 to slide back and forth along the transverse heat exchange section 33, which is used for self-cleaning the dust accumulated on the transverse heat exchange section 33. The self-cleaning effect achieved by combining with pulse blowing can avoid the transverse heat exchange section 33 from affecting its heat exchange effect due to excessive dust accumulation. When the working fluid in the cooling pipe 3 flows through a section of the fan unit, it is used to absorb heat and cool the fan unit. When the working fluid after absorbing heat flows through the heat exchange section, it exchanges heat with the normal temperature or relatively cold incoming air, which is beneficial to cooling the working fluid. At the same time, the transverse heat exchange section 33 heats the incoming air, which is beneficial to reducing the humidity of the incoming air, further avoiding the surface of the filter cartridge from being hardened and clogging the filter cartridge, and achieving a two-way beneficial effect.

[0022] In an embodiment of the present invention, the transverse heat exchange section 33 may be arranged in multiple sections along the radial direction of the exhaust pipe 103, for example Figure 5 As shown, the transverse heat exchange section 33 is arranged into three sections along the inner radial direction of the exhaust pipe 103, one of which 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, which is equivalent to the liquid inlet being forked into two branches at the transverse heat exchange section 33, and then discharged along the vertical liquid outlet section 34 respectively, thereby helping to further improve the heat exchange efficiency.

[0023] Specifically, the vertical liquid inlet section 32 and the vertical liquid outlet section 34 can be attached to or embedded in the outer wall of the exhaust pipe 103, and the horizontal liquid inlet section 31 and the horizontal liquid outlet section 35 can also be attached to or embedded in the inner top wall of the cylinder 101, so as to facilitate further heat exchange with the incoming air.

[0024] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4As shown, a support column 7 is vertically provided in the middle of the exhaust pipe 103, and the transverse heat exchange section 33 passes through and is fixed on the support column 7 transversely. A bottom groove 71 is opened at the bottom end of the support column 7, and the top end of the movable cylinder 5 passes through the bottom groove 71 and is slidably connected to the bottom groove 71. An elastic member 8 is connected between the top end of the movable cylinder 5 and the inner top wall of the bottom groove 71. The elastic member 8 can adopt existing conventional elastic components such as springs, so as to drive the movable cylinder 5 to move up and down elastically with the fluctuation of the exhaust air pressure in the exhaust pipe 103.

[0025] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4 As shown, the bottom end of the movable cylinder 5 is connected to a wind blocking plate 9, and the horizontal outward diameter of the wind blocking plate 9 is larger than the horizontal outward diameter of the support column 7, so as to further increase the contact area with the air intake, which is beneficial to drive the movable cylinder 5 to move elastically up and down, and at the same time, it is beneficial to further prevent the air intake from accumulating dust in the middle of the transverse heat exchange section 33 and on the support column 7.

[0026] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the self-cleaning part 4 includes a hard mesh 41 coated on the outside of the transverse heat exchange section 33. The hard mesh 41 can be made of a metal material with good heat conduction efficiency, is not easy to break and deform, and does not affect the heat exchange efficiency of the transverse heat exchange section 33. The hard mesh 41 is connected to one end of the support column 7 with a connecting rope 42, and the other end away from the support column 7 is connected to the transverse heat exchange section 33 with an elastic mesh belt 43. One end of the connecting rope 42 penetrates into the bottom groove 71 and is connected to the top of the movable cylinder 5. The hard mesh 41 is arranged in a mesh structure and the movable cylinder 5 moves up and down elastically, driving the connecting rope 42 to pull the hard mesh 41 to slide back and forth in the length direction of the outer side of the transverse heat exchange section 33, thereby achieving the effect of cleaning the dust accumulated on the outside of the transverse heat exchange section 33, and the loosened dust flows with the outlet air to the pulse filter cartridge dust collector 200 for treatment.

[0027] Optionally, the hard mesh 41 may also be in a spiral structure around the outer length direction of the transverse heat exchange section 33 .

[0028] In an embodiment of the present invention, optionally, Figure 2As shown, a heating tube 10 is provided on the support column 7 above the transverse heat exchange section 33, and a plurality of groups of heating tubes 10 are arranged at intervals from top to bottom. A humidity sensor is provided in the cylinder 101 of the cyclone dust collector 100. When the humidity sensor senses that the humidity in the cylinder 101 has risen, the heating tube 10 of the corresponding group is triggered to heat up. For example, if the humidity is sensed to have risen to a first preset value, the first group of heating tubes 10 near the top of the transverse heat exchange section 33 is triggered to start heating. If the humidity is sensed to have risen to a second preset value, the first group of heating tubes 10 and the second group of heating tubes 10 near the top of the first group of heating tubes 10 are triggered to start heating at the same time. By analogy, when the heat exchange in the transverse heat exchange section 33 is not enough to reduce the humidity to above the first preset value, the corresponding heating tube 10 is triggered to assist in heating to maintain a stable humidity requirement, and the heat of the heating tube 10 is carried away by the upward air outlet, which has limited impact on the transverse heat exchange section 33 spaced apart below.

[0029] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a sleeve 11 is sleeved on the support column 7, one end of the heating tube 10 is connected to the outside of the sleeve 11, a lifting portion 12 is provided inside the support column 7, a cross bar 13 is connected to the top of the lifting portion 12, the end of the cross bar 13 passes through the support column 7 outwards and is fixedly connected to the inside of the sleeve 11, wherein the lifting portion 12 can adopt existing conventional components such as a lifting cylinder, and the lifting cylinder is electrically connected to the humidity sensor, thereby driving the cross bar 13, the sleeve 11 and the corresponding heating tube 10 to rise and fall.

[0030] Among them, a fine groove 72 is opened on the outside of the support column 7 for the cross bar 13 to pass through and move up and down. The horizontal outer diameter of the wind blocking plate 9 is larger than the horizontal outer diameter of the support column 7, which is also beneficial to avoid dust accumulation along the fine groove 72 of the incoming air.

[0031] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.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 outer side of the movable sleeve 14, so that the heating tube 10 group can rotate along the axial direction of the outer ring of the sliding sleeve 11, and a positioning groove 104 is opened on the inner side wall of the exhaust pipe 103. The outer end of the heating tube 10 slides along the track of the positioning groove 104. When the lifting part 12 is all in the retracted state, as shown in FIG. Figure 5 , Figure 8As shown, each heating tube 10 and the transverse heat exchange section 33 are located in the same radial position in the exhaust pipe 103, which is conducive to avoiding dust accumulation on each heating tube 10. When the lifting part 12 extends upward, the sliding sleeve 11 and the movable sleeve 14 are driven 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, as shown in FIG. Figure 6 , Fig. 9 , Fig.10 As shown, the heating tube 10 is located in a radial position different from the transverse heat exchange section 33, thereby improving the heat exchange efficiency of the heating tube 10.

[0032] In an embodiment of the present invention, optionally, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, each heating tube 10 is provided with a tube cleaning member 15, and one end of the tube cleaning member 15 close to the support column 7 is connected to a split rope 16, the bottom end of the split rope 16 penetrates into the bottom groove 71, and is connected to the top of the movable cylinder 5. The tube cleaning member 15 and the split rope 16 adopt a structural design similar to the self-cleaning member 4 and the connecting rope 42, except that when the lifting part 12 is in a retracted state, the corresponding split rope 16 is in a relaxed state and will not drive the tube cleaning member 15 to move, thereby avoiding redundant transmission movement. When the lifting part 12 drives the heating tube 10 to rise, the corresponding split rope 16 is tightened to drive the tube cleaning member 15 to slide back and forth along the heating tube 10, thereby playing the same cleaning and dust removal role.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
