Description

Technical Field

[0001] This invention relates to the technical field of dust filtration and collection, and in particular to a latex dust filtration and collection device. Background Technology

[0002] Organic latex dust is continuously generated during the production of latex and silicone products, and it needs to be treated before being discharged.

[0003] Existing latex dust filtration and collection devices mostly use pulse jet bag filters as the processing equipment. After the dust-laden gas enters the housing, the dust is trapped on the outer surface of the filter bags, and the purified gas is discharged through the exhaust port. When the dust layer on the surface of the filter bags reaches a certain thickness, the pulse jet system releases high-pressure compressed air to impact the filter bags in the opposite direction, causing the surface dust to peel off. The detached dust falls into the unloading hopper below under gravity and is periodically discharged and recycled through the unloading mechanism. In this type of latex dust filtration and collection device, the air intake method is mostly a direct-connection pipeline, resulting in uneven airflow velocity distribution within the chamber. In high-velocity areas, the filter bags accumulate more dust than in low-velocity areas. In high-velocity areas, the filter bags are prone to clogging and caking. Furthermore, latex dust itself has high molecular adhesion, and after being captured, it easily forms a dense and strongly adhered dust cake layer on the surface of the filter fiber. Sometimes, the impact force of the pulse jet is insufficient to peel off the dust cake from the filter bags in high-velocity areas, affecting the filtration efficiency.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems: Existing latex dust filtration and collection devices are prone to clogging and caking of filter bags in high-speed areas, and the impact force of pulse jet cleaning is insufficient to peel off the powder cake from the filter bags in high-speed areas. Summary of the Invention

[0005] The purpose of this invention is to provide a latex dust filtration and collection device that solves the technical problems of existing latex dust filtration and collection devices, such as the easy clogging and caking of filter bags in high-speed areas, and the difficulty in removing the powder cake from the filter bags in high-speed areas due to the impact force of pulse jet blowing.

[0006] Invention solution: This invention provides a latex dust filtration and collection device, including a housing, a filter bag frame structure, a pulse assembly, and a discharge assembly. The housing is provided with an air inlet and an air outlet. The filter bag frame structure includes a mounting plate and several filter bag frame assemblies. The mounting plate is fixedly installed in the housing and has several mounting holes. The filter bag frame assembly includes a mounting head, an outer ring post, an inner ring post, several telescopic rings, an upper plate, a lower plate, and a spring. The mounting head is detachably installed in the mounting holes. The outer ring post is fixedly connected to the mounting head, and the inner ring post is fixedly connected to the mounting head and located inside the outer ring post. The several telescopic rings are slidably connected to the inner ring post. The upper plate is hinged to the upper telescopic ring of an adjacent telescopic ring, and the lower plate is hinged to the lower telescopic ring of an adjacent telescopic ring and to the upper plate. The spring is sleeved on the inner ring post and located between adjacent telescopic rings. The discharge assembly is connected to the lower part of the housing.

[0007] Furthermore, the inner ring column is provided with a limiting block.

[0008] Furthermore, the telescopic ring is provided with an arc-shaped air collecting part, and the inner diameter of the arc-shaped air collecting part of the telescopic rings gradually decreases from top to bottom.

[0009] Furthermore, the upper plate is provided with an upper weight-reducing groove, and the lower plate is provided with a lower weight-reducing groove.

[0010] Furthermore, the upper plate is provided with a sliding groove, and the upper end of the lower plate is slidably connected to the sliding groove.

[0011] Furthermore, the outer ring post is welded with a reinforcing ring, and the hinge joint between the upper plate and the lower plate is located between two adjacent reinforcing rings.

[0012] Furthermore, the inner ring post is provided with four posts, and between two adjacent telescopic rings, there are two pairs of upper plates and lower plates, and two springs are also distributed there, with the springs and upper plates being arranged alternately.

[0013] Furthermore, the telescopic ring, the upper plate, and the lower plate are made of plastic.

[0014] Furthermore, the air intake component includes a first air intake pipe, a first branch pipe, a second air intake pipe, a third air intake pipe, a second branch pipe, a fourth air intake pipe, a fifth air intake pipe, and a sixth air intake pipe; the first air intake pipe is connected to the first branch pipe, the two ends of the second air intake pipe and the third air intake pipe are respectively connected to the first branch pipe and the second branch pipe, the fourth air intake pipe, the fifth air intake pipe, and the sixth air intake pipe are respectively connected to the second branch pipe, and the fifth air intake pipe and the sixth air intake pipe are respectively provided with transverse air outlet grooves.

[0015] Beneficial Effects: This invention provides a latex dust filtration and collection device. Latex dust gas enters the housing through the inlet, passes through the filter bag, and exits through the outlet. When cleaning the dust adhering to the filter bag, a pulse assembly releases pulsed gas into the filter bag. Gas that does not contact the telescopic ring directly impacts the inside of the filter bag, while gas that does contact the telescopic ring impacts the ring. The telescopic ring compresses the upper and lower plates, and the hinge joint of the upper and lower plates, after being compressed, impacts the inside of the filter bag, knocking the dust off. The pulse assembly intermittently releases compressed gas, causing the spring and telescopic ring to repeatedly vibrate, repeatedly impacting the filter bag and thus peeling off the dust cake. This latex dust filtration and collection device makes peeling off the dust cake from the filter bag relatively easy. Attached Figure Description

The housing 1 is equipped with an air inlet 11 and an air outlet 12. The filter bag frame structure 2 includes a mounting plate 21 and several filter bag frame assemblies 22. The mounting plate 21 is fixedly installed on the housing 1 and has several mounting holes 211. The filter bag frame assembly 22 includes a mounting head 221, an outer ring post 222, an inner ring post 223, several telescopic rings 224, an upper plate 225, a lower plate 226, and a spring 227. The mounting head 221 is detachably installed in the mounting holes 211. 11. The outer ring column 222 is fixedly connected to the mounting head seat 221, and the inner ring column 223 is fixedly connected to the mounting head seat 221 and is located inside the outer ring column 222. Several telescopic rings 224 are slidably connected to the inner ring column 223. The upper plate 225 is hinged to the upper telescopic ring 224 of the adjacent telescopic ring 224, and the lower plate 226 is hinged to the lower telescopic ring 224 of the adjacent telescopic ring 224 and is hinged to the upper plate 225. The spring 227 is sleeved on the inner ring column 223 and is located between the adjacent telescopic rings 224. The unloading assembly 4 is connected to the lower part of the box 1.

[0027] Specifically, the housing 1 is a vertical closed cavity structure, with an air inlet 11 on the lower part of its side wall and an air outlet 12 on the upper part; the pulse assembly 3 includes an air tank, pipelines, and several nozzles for spraying air onto the filter bag; the filter bag skeleton structure 2 is used to install the filter bag, and the mounting plate 21 is horizontally fixed in the upper part of the inner cavity of the housing 1, dividing the housing 1 into an upper clean air chamber and a lower filter chamber. Several through mounting holes 211 are arrayed on the mounting plate 21, and each filter bag skeleton assembly 22 is installed in one mounting hole 211. The filter bag is fitted over the filter bag skeleton assembly 22, and the open end of the filter bag is sealed and fixed at the mounting head seat 221. The outer ring column 222 is a cylindrical cage-like outer support member, and its top end... The inner ring column 223 is a light axis structure, and its top end is also fixedly connected to the lower end face of the mounting head 221. Several telescopic rings 224 are arranged equidistantly along the axial direction. Between two adjacent telescopic rings 224, there are hinged upper plate 225 and lower plate 226. The upper plate 225 and lower plate 226 are hinged to each other to form a scissor-like structure that can be axially extended and radially expanded and contracted. The spring 227 is sleeved on the outside of the inner ring column 223. The upper and lower ends of the spring 227 respectively abut against two adjacent telescopic rings 224 to provide elastic restoring force for the telescopic rings 224. The unloading assembly 4 includes an unloading motor and an unloading roller plate, which are used to discharge the collected latex dust from the box 1.

[0028] In this embodiment, the inner ring post 223 is provided with a limiting block 228.

[0029] Specifically, the limiting block 228 is used to limit the axial sliding range of the telescopic ring 224.

[0030] In this embodiment, the telescopic ring 224 is provided with an arc-shaped air collecting part 2241, and the inner diameter of the arc-shaped air collecting part 2241 of the telescopic rings 224 gradually decreases from top to bottom.

[0031] Specifically, the inner diameter of several arc-shaped air collecting sections 2241 gradually decreases from top to bottom along the axial direction. This structure can gradually utilize the downward airflow, so that the telescopic rings 224 can be compressed.

[0032] In this embodiment, the upper plate 225 is provided with an upper weight reduction groove 2251, and the lower plate 226 is provided with a lower weight reduction groove 2261.

[0033] Specifically, the upper weight-reducing groove 2251 and the lower weight-reducing groove 2261 reduce the weight and improve the vibration response sensitivity during pulse jet blowing, while reducing the material cost of the overall frame. The lower plate 226 is hinged in the upper weight-reducing groove 2251, and the hinge between the upper plate 225 and the lower plate 226 moves outward under pressure.

[0034] In this embodiment, the upper plate 225 is provided with a sliding groove 2252, and the upper end of the lower plate 226 is slidably connected to the sliding groove 2252.

[0035] Specifically, the upper end of the lower plate 226 is embedded in the slide groove 2252 and slidably connected to the slide groove 2252. This structure can improve the smoothness of the telescopic movement of the upper plate 225 and the lower plate 226, avoid jamming at the hinge, and ensure stable and reliable radial expansion and contraction.

[0036] In this embodiment, the outer ring post 222 is welded with a reinforcing ring 229, and the hinge joint between the upper plate 225 and the lower plate 226 is located between two adjacent reinforcing rings 229.

[0037] Specifically, the reinforcing ring 229 can improve the radial structural strength of the outer ring column 222 and prevent the outer ring column 222 from deforming when the filter bag repeatedly expands and contracts.

[0038] In this embodiment, there are four inner ring posts 223. Between two adjacent telescopic rings 224, there are two pairs of upper plates 225 and lower plates 226, and two springs 227 are also distributed. The springs 227 and the upper plates 225 are arranged alternately.

[0039] Specifically, there are four inner ring columns 223, which are evenly distributed along the circumference. Between two adjacent telescopic rings 224, there are two pairs of upper plate members 225 and lower plate members 226 distributed along the circumference. At the same time, there are two spring members 227. The spring members 227 and the upper plate members 225 are staggered along the circumference to ensure that the force is uniform and the movement is smooth during the telescopic process.

[0040] In this embodiment, the telescopic ring 224, the upper plate 225, and the lower plate 226 are made of plastic.

[0041] Specifically, the telescopic ring 224, the upper plate 225, and the lower plate 226 are all made of engineering plastics, which are lightweight, wear-resistant, and dust-resistant, making them suitable for working environments with latex dust.

[0042] In this embodiment, the air intake component 11 includes a first air intake pipe 111, a first diverter pipe 112, a second air intake pipe 113, a third air intake pipe 114, a second diverter pipe 115, a fourth air intake pipe 116, a fifth air intake pipe 117, and a sixth air intake pipe 118. The first air intake pipe 111 is connected to the first diverter pipe 112. The two ends of the second air intake pipe 113 and the third air intake pipe 114 are respectively connected to the first diverter pipe 112 and the second diverter pipe 115. The fourth air intake pipe 116, the fifth air intake pipe 117, and the sixth air intake pipe 118 are respectively connected to the second diverter pipe 115. The fifth air intake pipe 117 and the sixth air intake pipe 118 are respectively provided with transverse air outlet grooves 119.

[0043] Specifically, the first air inlet pipe 111 is the main air inlet pipe, and its outlet end is connected to the middle air inlet end of the first diverter pipe 112; the air inlet ends of the second air inlet pipe 113 and the third air inlet pipe 114 are respectively connected to the two end outlets of the first diverter pipe 112, and the air outlet ends of the second air inlet pipe 113 and the third air inlet pipe 114 are respectively connected to the two end inlets of the second diverter pipe 115, completing the first stage of diversion. The air inlet ends of the fourth air inlet pipe 116, the fifth air inlet pipe 117 and the sixth air inlet pipe 118 are all connected to the side wall outlet end of the second diverter pipe 115, completing the second stage of diversion; among them, the fourth air inlet pipe 116 has a straight-out end structure, and the fifth air inlet pipe 117 and the sixth air inlet pipe 118 are each provided with a long strip-shaped transverse air outlet groove 119. The transverse air outlet groove 119 extends in the horizontal direction, so that the air outlet diffuses in the lateral direction, avoiding the airflow directly impacting the filter bag. By combining two-stage air diversion with lateral air outlet, the single-path air intake is evenly distributed into the filter chamber of housing 1, greatly improving the uniformity of airflow distribution.

[0044] Dust removal operation: When the dust layer on the filter bag surface reaches the set thickness, the pulse component 3 is activated, releasing high-pressure compressed air downwards. The high-pressure airflow rushes into the filter bag and impacts the telescopic rings 224 of each layer. The telescopic rings 224 slide downwards along the inner ring column 223 under the airflow pressure, compressing the spring component 227. At the same time, the hinge point between the upper plate component 225 and the lower plate component 226 expands outwards, causing the filter bag to expand radially. When the airflow impact force weakens, the spring component 227 rebounds, pushing the telescopic rings 224 upwards, and the hinge point contracts inwards, causing the filter bag to return to its radial position. This reciprocating motion produces a combined effect of axial vibration and radial expansion and contraction of the filter bag, completely shaking off the dense latex dust cake adhering to the surface. The peeled dust falls into the unloading component 4 at the bottom of the housing 1 under gravity, and is periodically discharged and recycled through the unloading mechanism.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
