Description

Technical Field

[0001] This invention relates to the field of flue gas treatment technology, and more particularly to a smoke removal device for coffee processing. Background Technology

[0002] Coffee roasting produces a large amount of smoke, oils, and volatile organic compounds. These substances not only pollute the environment and affect neighborly relations, but more importantly, they severely affect the final flavor of coffee beans and damage equipment. Therefore, efficient smoke removal equipment is standard equipment in modern coffee roasting plants.

[0003] Patent CN209714629U discloses a coffee bean roasting smoke purifier, including a purifier body. An air inlet and an air outlet are respectively located at both ends of the purifier body's exterior. Both the air inlet and outlet are connected to the purifier body via variable diameter ports. A first filter and a second filter are respectively located on both sides of the purifier body's interior. An electric field is established between the first and second filters, formed by a first voltage chamber and a second voltage chamber. An oil drain port is located at the bottom of the purifier body. This invention effectively solves the problems of existing coffee bean roasting smoke purifiers being difficult to maintain and clean, labor-intensive, and having low purification efficiency.

[0004] Coffee fumes are liquid at room temperature, but may be semi-solid or highly viscous at the operating temperature of an electric field. They can adhere to the dust collection electrode and corona wire, forming very stubborn grease. Existing devices cannot efficiently and automatically remove the stubborn grease adhering to the electrostatic components without interrupting normal equipment operation or significantly increasing maintenance complexity, so as to maintain the long-term stable purification performance of the equipment. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot efficiently and automatically remove stubborn grease deposits adhering to electrostatic components without interrupting normal equipment operation or significantly increasing maintenance complexity, thereby maintaining the long-term stable purification performance of the equipment. Therefore, this invention proposes a smoke removal device for coffee processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smoke removal device for coffee processing includes: a cabinet, filters disposed at both ends of the cabinet, and an ultraviolet lamp strip assembly disposed near the smoke inlet end of the cabinet. The cabinet is equipped with a first electrostatic component and a second electrostatic component. The first electrostatic component is disposed at the smoke inlet end of the cabinet, and the second electrostatic component is disposed at the air outlet end of the cabinet. The first electrostatic component includes a first electric field box and two sets of dust collection components. The electric field box is slidably mounted inside the cabinet, and the two sets of dust collection components are symmetrically arranged inside the electric field box. The dust collection component includes two rotating shafts, two transmission belts, four transmission gears, and multiple dust collection plates. The two rotating shafts are symmetrically rotated and installed inside the electric field box. The four transmission gears are respectively fixedly sleeved on both ends of the two rotating shafts. The two transmission belts are symmetrically arranged and respectively meshed on the two symmetrical transmission gears. The multiple dust collection plates are equidistantly fixedly connected between the two transmission belts. A cleaning component is provided below the dust collection component, which is used to contact and clean the rotating dust collection plate.

[0007] Preferably, the second electrostatic component includes a second electric field box and multiple electrode plates. The second electric field box is slidably mounted inside the cabinet, and the multiple electrode plates are equidistantly and vertically fixed inside the second electric field box.

[0008] Preferably, the cleaning assembly includes a sealing shell, two drive shafts, two elastic rods, two fixed seats, and two steel wire brush sleeves. The sealing shell is fixedly installed at the bottom of the first electric field box and has two openings on both sides for the rotation of the dust collection plates. The two drive shafts are symmetrically rotatably installed on the side wall of the electric field box, and the two fixed seats are symmetrically fixedly connected to the other side wall of the electric field box. The elastic rods are fixedly connected between the drive shafts and the fixed seats, and the steel wire brush sleeves are fixedly connected to the elastic rods.

[0009] Preferably, the cabinet is equipped with a drive assembly for driving the drive shaft and the rotating shaft to rotate. The drive assembly includes a motor, a drive rod, two first side bevel gears and two drive bevel gears. The motor is fixedly installed on the side of the second electric field box. The drive rod is fixedly connected to the drive end of the motor. One end of the rotating shaft passes through the first electric field box, and the two drive bevel gears are respectively fixedly connected to the ends of the two rotating shafts. The two first side bevel gears are fixedly connected to the drive rod and are respectively meshed with the drive bevel gears.

[0010] Preferably, a linkage component is provided between the rotating shaft and the cleaning component. The linkage component includes two linkage gears and a main gear. The main gear is fixedly connected to the drive shaft, and the two linkage gears are respectively sleeved on the ends of the two drive shafts. Both linkage gears are meshed with the main gear.

[0011] Preferably, a scraping component is provided on the side of the second electrostatic component close to the first electrostatic component, and the scraping component is used to clean both sides of the electrode plate from top to bottom.

[0012] Preferably, the scraping assembly includes a telescopic rod, a mounting plate, and multiple cleaning strips. The telescopic rod is horizontally arranged, the mounting plate is fixedly connected to the end of the telescopic rod, and the multiple cleaning strips are fixedly connected to the side of the mounting plate, with the cleaning strips positioned between two adjacent electrode plates.

[0013] Preferably, a lifting component is provided between the first electrostatic component and the second electrostatic component, and the lifting component is used to drive the telescopic rod to move up and down.

[0014] Preferably, the lifting assembly includes a reciprocating lead screw, a threaded sleeve, and a limiting post. The reciprocating lead screw is rotatably installed inside the cabinet on one side near the drive rod. The threaded sleeve is fitted onto the reciprocating lead screw. The limiting post is symmetrically and fixedly connected to the other side of the cabinet. One end of the telescopic rod is fixedly connected to the side of the threaded sleeve. The mounting plate is slidably and limitedly mounted on the limiting post on the side away from the telescopic rod.

[0015] Preferably, a second side bevel gear is fixedly sleeved on the drive rod, and a control gear is fixedly connected to the reciprocating screw, the control gear meshing with the second side bevel gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Two independent dust collection components are set in the first electric field box. Each dust collection component is essentially a "tracked dust collection unit", which makes all the dust collection plates rotate as a whole. The dust collection plates are no longer stationary, but move continuously and slowly. The moving dust collection plates themselves can prevent excessive local deposition of oil stains to a certain extent. During the rotation of the dust collection plates, they will pass through the cleaning components below, which creates conditions for online cleaning. This invention solves the problem of oil stains accumulation in electrostatic components by cooperating with the tracked dust collection plates and the cleaning components, ensuring that the smoke removal equipment can operate continuously without reducing efficiency. 2. By setting two different electrostatic components, the purification effect of oil fumes can be improved. The dust collection plates of the first electrostatic component are all set horizontally, while the plates of the second electrostatic component are set vertically. The two electrostatic components comb the flue gas in different directions, thereby ensuring that the flue gas is fully treated and purified. 3. The elastic rod structure allows the steel rope brush sleeve to adapt to the slight deformation or installation error of the dust collection plate, ensuring uniform and continuous cleaning force. At the same time, the cleaning process and the purification process are carried out simultaneously, realizing cleaning while working without stopping the machine, which greatly improves the utilization rate of the equipment. 4. The cooperation between the drive component and the linkage component allows the rotation of the dust collection plate and the movement of the cleaning component to be driven simultaneously by a single power source. The main drive power is split, with one part used to drive the dust collection track and the other part used to drive the cleaning brush. This optimizes the overall structure, reduces the space required, and reduces energy consumption and cost. Strict motion synchronization is achieved through gear meshing to ensure that the cleaning action and the movement of the dust collection plate are precisely matched. 5. The cleaning strips are precisely inserted into the gaps of multiple vertically fixed electrode plates. By moving the entire scraping assembly up and down, multiple cleaning strips can scrape off the oil stains on both sides of the electrode plates. The cleaning strips go deep into the gaps of the electrode plates and can clean the opposite surfaces of two adjacent electrode plates at the same time, which is highly efficient. 6. A highly efficient power transmission chain has been constructed. The motor drives the drive rod to rotate, which can simultaneously drive the dust collection component, the cleaning brush, and the scraping component. This highly integrated linkage greatly simplifies the overall structure of the machine and improves its reliability. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0021] Reference Figures 1-9 A smoke removal device for coffee processing includes: a cabinet 1, filters 10 disposed at both ends of the cabinet 1, and an ultraviolet lamp strip assembly 11 disposed near the smoke inlet end of the cabinet 1. The cabinet 1 is provided with a first electrostatic component 2 and a second electrostatic component 3. The first electrostatic component 2 is disposed at the smoke inlet end of the cabinet 1, and the second electrostatic component 3 is disposed at the air outlet end of the cabinet 1. The first electrostatic component 2 includes a first electric field box 21 and two sets of dust collection components 22. The electric field box is slidably mounted inside the cabinet 1, and the two sets of dust collection components 22 are symmetrically arranged inside the electric field box. The dust collection component 22 includes two rotating shafts 221, two transmission belts 222, four transmission gears 223, and multiple dust collection plates 224. The two rotating shafts 221 are symmetrically rotated and installed inside the electric field box. The four transmission gears 223 are respectively fixedly sleeved on both ends of the two rotating shafts 221. The two transmission belts 222 are symmetrically arranged and respectively meshed on the two symmetrical transmission gears 223. The multiple dust collection plates 224 are equidistantly fixedly connected between the two transmission belts 222. A cleaning component 4 is provided below the dust collection component 22, and the cleaning component 4 is used to contact and clean the rotating dust collection plate 224.

[0022] In the embodiment of the above technical solution, the electrostatic dust collection step is divided into two separately set electrostatic dust collection components. Since the first electrostatic component 2 comes into contact with the oil fume first, a lot of oil stains adhere to the first electrostatic component 2, which causes the oil stains on the surface of the dust collection plate 224 to accumulate quickly and be difficult to clean automatically.

[0023] Two independent dust collection components 22 are set in the first electric field box 21. Each dust collection component 22 is essentially a "tracked dust collection unit" consisting of two rotating shafts 221, a transmission belt 222, a transmission gear 223, and multiple dust collection plates 224 fixed between the transmission belts 222. Driven by the drive component 5, the rotating shafts 221 rotate, and through the transmission gears 223 and the transmission belt 222, all the dust collection plates 224 rotate as a whole. The dust collection plates 224 are no longer stationary, but move continuously and slowly. The moving dust collection plates 224 can prevent excessive local deposition of oil stains to a certain extent. During the rotation, the dust collection plates 224 pass through the cleaning component 4 below, creating conditions for online cleaning.

[0024] This invention solves the problem of oil buildup in electrostatic components by combining the tracked dust collection plate 224 with the cleaning component 4, ensuring that the smoke removal equipment can operate continuously without reducing its efficiency.

[0025] The preferred technical solution in this embodiment is: Reference Figure 2-4 The second electrostatic component 3 includes a second electric field box 31 and a plurality of electrode plates 32. The second electric field box 31 is slidably mounted inside the cabinet 1, and the plurality of electrode plates 32 are equidistantly and vertically fixed inside the second electric field box 31.

[0026] By setting two different electrostatic components, the purification effect of oil fumes can be improved. The dust collection plates 224 of the first electrostatic component 2 are all set horizontally, while the plates 32 of the second electrostatic component 3 are set vertically. The two electrostatic components comb the flue gas in different directions, thereby ensuring that the flue gas is fully treated and purified.

[0027] Reference Figure 5-8The cleaning assembly 4 includes a sealing shell 41, two drive shafts 42, two elastic rods 43, two fixed seats 44, and two steel wire brush sleeves 45 (the steel wire brush sleeves 45 are made of stainless steel wire, and the elastic rods are made of spring steel). The sealing shell 41 is fixedly installed at the bottom of the first electric field box 21, and has two openings on both sides for the rotation of the dust collection plate 224. The two drive shafts 42 are symmetrically rotated and installed on the side wall of the electric field box, and the two fixed seats 44 are symmetrically fixedly connected to the other side wall of the electric field box. The elastic rods 43 are fixedly connected between the drive shafts 42 and the fixed seats 44, and the steel wire brush sleeves 45 are fixedly connected to the elastic rods 43.

[0028] Since multiple dust collection plates 224 rotate during operation, in order to ensure the dust collection effect of the dust collection plates 224, it is necessary to effectively clean the dust collection plates 224 during their rotation.

[0029] The cleaning component 4 is located below the first electrostatic component 2. Its core consists of two steel wire brush sleeves 45 supported by elastic rods 43. When the dust collection plate 224 rotates to the cleaning station, its surface will come into contact with the steel wire brush sleeves 45. The pressure provided by the elastic rods 43 ensures that the brush sleeves are in close contact with the surface of the plate 32. As the dust collection plate 224 moves, the steel wire brush sleeves 45 will scrape and brush away the oil and dirt adhering to its surface, thereby completing the cleaning of the dust collection plate 224.

[0030] The elastic rod 43 structure allows the steel rope brush sleeve 45 to adapt to the slight deformation or installation error of the dust collection plate 224, ensuring uniform and continuous effective cleaning force. At the same time, the cleaning process and the purification process are carried out simultaneously, realizing cleaning while working without stopping the machine, which greatly improves the utilization rate of the equipment.

[0031] The elastic contact and rotating scraping of the steel wire brush sleeve 45, as well as the reciprocating scraping of the cleaning strip 63 against the fixed electrode plate 32, make it far superior to traditional vibration methods in removing viscous oil stains.

[0032] Reference Figure 2-6 The cabinet 1 is equipped with a drive assembly 5, which is used to drive the drive shaft 42 and the rotating shaft 221 to rotate. The drive assembly 5 includes a motor 51, a drive rod 52, two first side bevel gears 53 and two drive bevel gears 54. The motor 51 is fixedly installed on the side of the second electric field box 31. The drive rod 52 is fixedly connected to the drive end of the motor 51. One end of the rotating shaft 221 passes through the first electric field box 21, and the two drive bevel gears 54 are respectively fixedly connected to the ends of the two rotating shafts 221. The two first side bevel gears 53 are fixedly connected to the drive rod 52 and are respectively meshed with the drive bevel gears 54. A linkage component 9 is provided between the rotating shaft 221 and the cleaning component 4. The linkage component 9 includes two linkage gears 91 and a main gear 92. The main gear 92 is fixedly connected to the drive shaft. The two linkage gears 91 are respectively sleeved on the ends of the two drive shafts 42. Both linkage gears 91 are meshed with the main gear 92.

[0033] The motor 51 of the drive assembly 5 transmits power to the rotating shaft 221 through the meshing of the drive rod 52, the first side bevel gear 53, and the drive bevel gear 54, driving the dust collection component 22 to rotate. At the same time, through the two linkage gears 91 and the main gear 92 of the linkage assembly 9, the rotational motion of the dust collection component rotating shaft 221 is transmitted to the drive shaft 42 of the cleaning assembly 4, driving the steel rope brush sleeve 45 to rotate, thereby enhancing the cleaning effect.

[0034] The cooperation between the drive component 5 and the linkage component 9 allows for the simultaneous rotation of the dust collection plate 224 and the movement of the cleaning component 4 via a single power source. This splits the main drive power, with one part used to drive the dust collection track and the other part used to drive the cleaning brush. This optimizes the overall structure, reduces the usable space, and lowers energy consumption and cost. Strict motion synchronization is achieved through gear meshing, ensuring precise matching between the cleaning action and the movement of the dust collection plate 224.

[0035] Reference Figure 9 The second electrostatic component 3 is provided with a scraping component 6 on the side close to the first electrostatic component 2. The scraping component 6 is used to clean both sides of the electrode plate 32 from top to bottom. The scraping assembly 6 includes a telescopic rod 61, a mounting plate 62, and multiple cleaning strips 63 (the cleaning strips 63 are made of rubber). The telescopic rod 61 is horizontally arranged, the mounting plate 62 is fixedly connected to the end of the telescopic rod 61, and the multiple cleaning strips 63 are fixedly connected to the side of the mounting plate 62, and the cleaning strips 63 are arranged between two adjacent electrode plates 32.

[0036] During long-term use, oil stains will also adhere to the multiple plates 32 of the second electrostatic component 3, affecting the purification efficiency of the second electrostatic component 3.

[0037] Multiple cleaning strips 63 are precisely inserted into the gaps of multiple vertically fixed electrode plates 32. By moving the entire scraping assembly 6 up and down, the multiple cleaning strips 63 can scrape off the oil stains on both sides of the electrode plates 32. The cleaning strips 63 directly penetrate into the gaps of the electrode plates 32, and can clean the opposite surfaces of two adjacent electrode plates 32 at the same time, which is highly efficient.

[0038] Meanwhile, since a large amount of oil stains may adhere to the electrode plate 32, the side thickness of the electrode plate 32 will change after the oil stains solidify. By controlling the extension and retraction of the telescopic rod 61, pressure can be applied to both sides of the cleaning strip 63, thereby deeply cleaning the solidified oil stains and ensuring the cleaning effect of the electrode plate 32.

[0039] This invention achieves comprehensive cleaning coverage, not only solving the cleaning problem of the dynamic dust collection plate 224, but also solving the automatic cleaning problem of the second-stage fixed plate 32 through the scraping component 6, thus realizing all-round maintenance of the core electrostatic components.

[0040] Reference Figure 4 and Figure 9 A lifting component 7 is provided between the first electrostatic component 2 and the second electrostatic component 3. The lifting component 7 is used to drive the telescopic rod 61 to move up and down. The lifting assembly 7 includes a reciprocating lead screw 71, a threaded sleeve 72, and a limiting post 73. The reciprocating lead screw 71 is rotatably installed inside the cabinet 1 on one side near the drive rod 52. The threaded sleeve 72 is sleeved on the reciprocating lead screw 71. The limiting post 73 is symmetrically and fixedly connected to the other side of the cabinet 1. One end of the telescopic rod 61 is fixedly connected to the side of the threaded sleeve 72. The mounting plate 62 is slidably and limitedly mounted on the limiting post 73 on the side away from the telescopic rod 61. The drive rod 52 is provided with a rotating component 8, which includes a second side bevel gear 81 and a control gear 82. The second side bevel gear 81 is sleeved on the drive rod 52, and the control gear 82 is fixedly connected to the reciprocating screw 71. The control gear 82 is meshed with the second side bevel gear 81.

[0041] A second side bevel gear 81 is installed on the drive rod 52. By meshing with the control gear 82, the main drive power is diverted again, driving the reciprocating screw 71 to rotate, thereby driving the lifting assembly 7 to work.

[0042] The reciprocating screw 71 drives the threaded sleeve 72 and the limiting post 73 to move up and down periodically. Through the reciprocating screw 71 mechanism, the rotational motion is converted into linear, automatically reciprocating motion, realizing the comprehensive and automated scraping of the fixed electrode plate 32.

[0043] Meanwhile, the present invention constructs a highly efficient power transmission chain. The motor 51 drives the drive rod 52 to rotate, which can simultaneously drive the dust collection component 22, the cleaning brush, and the scraping component 6. This highly integrated linkage greatly simplifies the overall structure and improves reliability.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
