Description

Technical Field

[0001] This application belongs to the technical field of papermaking wire production equipment, and more specifically, it relates to a papermaking wire antistatic packaging equipment. Background Technology

[0002] The paper wire is an accessory on the paper machine. It is the most important medium for paper web formation and dewatering, and plays a key role in the quality of the finished paper. It is a consumable device used for paper dewatering in the paper industry.

[0003] Most papermaking wire meshes are currently woven from polyester monofilaments, nylon monofilaments, etc. During its operations, the applicant frequently receives feedback from customers that the papermaking wire meshes adhere to a lot of dust and impurities, requesting improvements in product quality. Following traditional methods, the applicant has added numerous anti-static devices during the papermaking wire mesh production process to prevent dust adsorption and improve product quality; however, this problem has not been significantly improved.

[0004] After in-depth research, the inventors discovered that the dust on the papermaking wire mesh was not introduced during the production process, but rather during the final packaging process. The friction of the papermaking wire mesh generates static electricity, which attracts dust and leads to a decline in the quality of the papermaking wire mesh. Summary of the Invention

[0022] In some embodiments, the force storage stopper is a stop plate extending inward from the edge of the groove.

[0023] In some embodiments, the rotating knock structure comprises:

[0024] Two mounting plates are mounted on the wheel shaft and form a mounting space in the middle, the two mounting plates are respectively provided with a plurality of radial guide grooves distributed around the wheel shaft, and the radial guide grooves on the two mounting plates are arranged opposite to each other; and

[0025] A plurality of elastic pushing assemblies are arranged around the wheel shaft; each of the elastic pushing assemblies comprises a sliding piece and a pushing piece, two ends of the sliding piece are slidingly arranged in the corresponding radial guide slots of the two mounting plates, the pushing piece is connected to the sliding piece, and an outer end of the pushing piece is elastic and extends outward from the outer periphery of the mounting space to contact and elastically push the tensioning section;

[0027] Two ends of the sliding piece of each elastic pushing assembly are respectively connected with a counterweight, so that when the rotation reaches a predetermined rotational speed, the sliding piece is driven to slide radially outward against the pulling force of the tension spring, so that the outer end of the pushing piece restores contact with the tensioning section.

[0028] In some embodiments, the outer end of the pushing piece is curved away from the rotation direction of the impeller, and the end of the outer end of the pushing piece is curved inward of the outer end of the pushing piece, to avoid the end of the outer end of the pushing piece from contacting the tensioning section;

[0029] An outer side of the outer end of the pushing piece is provided with a protrusion, and the protrusion is suitable for elastically pushing the tensioning section.

[0033] The upper negative pressure dust suction port and the lower negative pressure dust suction port can simultaneously remove dust and other impurities on two surfaces of the papermaking net, and collect the impurities to avoid secondary pollution. Moreover, the upper negative pressure dust suction port can accelerate the airflow in the airflow passage. The electrostatic removal airflow of the electrostatic removal air source can be better divided into two parts according to the expectation, and the suction force of the upper negative pressure dust suction port and the lower negative pressure dust suction port can be adjusted respectively, so that the size of the two airflows can be controlled. The two supporting rollers tension the papermaking net to form a tension section. The electrostatic removal airflow of the electrostatic removal air source is blown into the tension section of the papermaking net, so that the electrostatic removal airflow flows through the airflow passage and contacts the tension section of the papermaking net, thereby eliminating the static electricity of the papermaking net. The electrostatic removal airflow partially penetrates the tension section and enters the lower negative pressure dust suction port, so that most of the dust and other impurities attached to the papermaking net are blown into the lower negative pressure dust suction port. The remaining part of the electrostatic removal airflow enters the upper negative pressure dust suction port after pushing the impeller in the airflow passage, so that the impurities that are not easy to penetrate the papermaking net are blown backward into the upper negative pressure dust suction port.

A large amount of airflow enters the upper negative pressure dust suction port after pushing the impeller in the airflow passage, so that the rotating knock structure can violently knock the tension section, so that even if the airflow penetrating the papermaking net is small, the impurities inside the papermaking net can be easily blown out under vibration. For papermaking nets with high air permeability (such as single-layer nets), most of the electrostatic removal airflow of the electrostatic removal air source penetrates the tension section of the papermaking net and enters the lower negative pressure dust suction port below, so that most of the impurities can be blown into the lower negative pressure dust suction port below. Only a small amount of airflow enters the upper negative pressure dust suction port after pushing the impeller in the airflow passage, so that the rotating knock structure only slightly knocks the tension section or does not knock it at all, which can reduce the contact between the rotating knock structure and the tension section to avoid scratching, thereby facilitating the improvement of the winding speed of the net winding roller and the packaging efficiency.

DETAILED DESCRIPTION

[0049] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, and not to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0052] In addition, the terms "first", "second", "third", etc. are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of", "several" is two or more, unless otherwise explicitly specified.

[0053] In the current papermaking net production process, generally, an electrostatic removal device is used in the single filament production, whole diameter, weaving, shaping and other links, and dust and other impurities are strictly controlled, but there is no special dust removal device in the packaging link. The inventor found through in-depth research that during the winding and packaging process of the papermaking net, static electricity will also be generated due to friction, dust and impurities will be adsorbed, and the quality of the papermaking net will be reduced.

[0054] There are various specifications of papermaking nets, and different papermaking nets have different air permeabilities. The lower the air permeability of the papermaking net, the greater the density of the monofilament, the more the layers, and the smaller the pores. The higher the air permeability of the papermaking net, the smaller the density of the monofilament, the fewer the layers, and the larger the pores. For the papermaking net with high air permeability, most of the dust and other impurities float on the surface and are relatively easy to remove. However, for the papermaking net with low air permeability, dust and other impurities are easily hidden inside, and dust is also easily stuck inside, which is relatively difficult to be completely removed. Therefore, there is no general dust removal device for different papermaking nets at present.

[0055] For a better understanding of the present application, reference will be made by way of example to the accompanying drawings in which: Figures 1 to 10 A papermaking net electrostatic elimination packaging device is provided, which comprises a net winding roller, two supporting rollers and a dust removal assembly.

[0056] The net winding roller is suitable for winding the papermaking net. The two supporting rollers are located on the feeding side of the net winding roller and are arranged in parallel and at intervals. The papermaking net is suitable for winding on the net winding roller after passing through the two supporting rollers, and the papermaking net forms a tensioning section between the two supporting rollers. The dust removal assembly is located between the two supporting rollers and comprises an electrostatic elimination power supply, an upper negative pressure dust suction port and a lower negative pressure dust suction port. The electrostatic elimination power supply and the upper negative pressure dust suction port form an airflow channel in the front-rear direction above the tensioning section, and a impeller driven by airflow is arranged in the airflow channel. A rotating and knocking structure suitable for knocking the tensioning section is arranged on the shaft of the impeller. The lower negative pressure dust suction port is located below the tensioning section and is in communication with the airflow channel through the tensioning section. Part of the electrostatic elimination airflow in the airflow channel passes through the tensioning section into the lower negative pressure dust suction port, and part of the electrostatic elimination airflow pushes the impeller and then enters the upper negative pressure dust suction port.

[0057] Compared with the prior art, the papermaking net electrostatic elimination packaging device of the present application can eliminate static electricity and dust from the papermaking net and then wind and package the papermaking net, thereby avoiding product quality problems.

[0058] The upper negative pressure dust suction port and the lower negative pressure dust suction port can simultaneously remove dust and other impurities on two surfaces of the papermaking net, and collect the impurities to avoid secondary pollution. In addition, the upper negative pressure dust suction port can accelerate the airflow in the airflow passage. The electrostatic removal airflow of the electrostatic removal air source can be better divided into two parts according to the expectation, and the suction force of the upper negative pressure dust suction port and the lower negative pressure dust suction port can be adjusted respectively, so that the size of the two airflows can be controlled. The two supporting rollers tension the papermaking net to form a tension section. The electrostatic removal airflow of the electrostatic removal air source is blown into the airflow passage and contacts the tension section of the papermaking net, so as to eliminate the static electricity of the papermaking net. The electrostatic removal airflow partially penetrates the tension section into the lower negative pressure dust suction port, and blows most of the dust and other impurities attached to the papermaking net into the lower negative pressure dust suction port. The remaining part of the electrostatic removal airflow enters the upper negative pressure dust suction port after driving the impeller in the airflow passage, and blows the impurities that are not easy to penetrate the papermaking net into the upper negative pressure dust suction port.

[0059] The embodiment of the application adds a vibration structure in the papermaking net packaging and dust removal to improve the dust removal effect. The electrostatic removal airflow drives the impeller in the airflow passage, thereby driving the rotating knock structure to knock the tension section, so that the impurities attached to the papermaking net are separated under vibration.

[0060] The embodiment of the application can automatically adapt to different types of papermaking nets without manual intervention. For papermaking nets with low air permeability, the packaging efficiency can be improved, and for papermaking nets with high air permeability, the dust removal effect can be improved to ensure product quality. For papermaking nets with low air permeability (such as high-density single-layer nets, double-layer nets, and three-layer nets), only a small part of the airflow of the electrostatic removal air source can penetrate the tension section of the papermaking net into the lower negative pressure dust suction port below, and a large amount of airflow enters the upper negative pressure dust suction port after driving the impeller in the airflow passage, so that the rotating knock structure can knock the tension section violently, so that even if the airflow penetrating the papermaking net is small, the impurities inside the papermaking net can be easily blown out under vibration. For papermaking nets with high air permeability (such as single-layer nets), most of the airflow of the electrostatic removal air source penetrates the tension section of the papermaking net into the lower negative pressure dust suction port below, which can blow most of the impurities into the lower negative pressure dust suction port below. Only a small amount of airflow enters the upper negative pressure dust suction port after driving the impeller in the airflow passage, so that the rotating knock structure only slightly knocks the tension section or does not knock it at all, which can reduce the contact between the rotating knock structure and the tension section to avoid scratching, thereby facilitating the improvement of the winding speed of the net winding roller and the packaging efficiency.

[0061] In a specific application, the application can not only solve the problem that the papermaking net is easy to adsorb dust in the packaging process, but also due to the good dust removal effect of the application, the papermaking net production line adopting the application can reduce the dust removal requirement to a certain extent, and the static electricity removal equipment in each process before packaging is omitted, and the dust removal is completed in the packaging process. As a typical papermaking net production line adopting the application, it includes a diameter adjusting device, a weaving device, a shaping device, and a papermaking net static electricity removal and packaging device of the application. In addition to the papermaking net static electricity removal and packaging device of the application, the other devices do not include a static electricity removal device for monofilament or dustproof net.

[0062] In a specific implementation, the winding roller and the two supporting rollers are arranged on the support, the two supporting rollers are located in front of the winding roller, and the two supporting rollers are horizontally arranged. The papermaking net is wound on the winding roller after passing through the two supporting rollers from the front, the papermaking net is tensioned between the two supporting rollers to form a tensioning section, so that the tensioning section can vibrate under the repulsion of the rotating repulsion structure, thereby separating the internal dust and impurities.

[0063] The dust removal assembly can also be fixed on the support. The dust removal assembly can use an electrostatic blower as an electrostatic source to neutralize the static electricity on the papermaking net by blowing ionized airflow.

[0064] The upper negative pressure dust suction port and the lower negative pressure dust suction port of the dust removal assembly are respectively connected to the negative pressure blower. The electrostatic source and the upper negative pressure dust suction port are connected through a shell to form an airflow channel above the papermaking net, so that the electrostatic airflow blown by the electrostatic source can flow through the airflow channel from above the papermaking net and finally enter the upper negative pressure dust suction port. This part of the electrostatic airflow can neutralize the static electricity on the papermaking net, and also blow the dust and impurities on the surface of the papermaking net into the upper negative pressure dust suction port. The lower negative pressure dust suction port is located below the tensioning section of the papermaking net. Since the papermaking net has pores, part of the electrostatic airflow blown from the electrostatic source will penetrate the tensioning section of the papermaking net and enter the lower negative pressure dust suction port. This part of the electrostatic airflow that penetrates the tensioning section of the papermaking net can completely neutralize the static electricity on the papermaking net, and also completely blow the dust and impurities inside the papermaking net into the lower negative pressure dust suction port.

[0065] The airflow passage of the dust removal assembly is provided with an impeller, and a rotating push structure is arranged on the wheel shaft of the impeller. When the electrostatic airflow flows through the airflow passage, the impeller can be pushed to rotate, and in turn drive the rotating push structure to push the tensioning section of the papermaking net. The impeller is pushed by the airflow in the airflow passage. On the one hand, the impeller forms a certain resistance to the airflow in the airflow passage, so that the electrostatic airflow in the airflow passage can better penetrate the papermaking net downward, and better eliminate the static electricity of the papermaking net, especially for the papermaking net with lower air permeability. On the other hand, when facing the papermaking nets with different air permeability, the rotating speed of the impeller can be automatically changed, so that the pushing of the rotating push structure is enhanced or weakened. The airflow penetrating the papermaking net with higher air permeability is more, so that the airflow in the airflow passage is smaller, the rotating speed of the impeller is reduced or even stopped, and the pushing of the rotating push structure is weakened or even stopped. The airflow penetrating the papermaking net with lower air permeability is less, so that the airflow in the airflow passage is larger, the rotating speed of the impeller is higher, and the pushing of the rotating push structure is more intense.

[0066] Referring to Figures 1 to 3 , as a specific embodiment of the papermaking net electrostatic removal packaging equipment provided by the present application, a U-shaped air guide groove is arranged between the electrostatic source and the upper negative pressure dust suction port, the U-shaped air guide groove is arranged above the tensioning section and closes both sides of the tensioning section to form an airflow passage. The middle part of the U-shaped air guide groove is provided with a groove to accommodate the impeller and the rotating push structure.

[0067] In the embodiment, the U-shaped air guide groove is used to form the airflow passage, so that the electrostatic airflow can better flow from the electrostatic source to the upper negative pressure dust suction port along the tensioning section, and the contact with the tensioning section is more sufficient.

[0068] In the specific implementation, the U-shaped air guide groove is connected between the electrostatic source and the upper negative pressure dust suction port. The middle position of the U-shaped air guide groove is protruded upward to form a groove, and the impeller and the rotating push structure are installed in the groove, and the both ends of the wheel shaft are installed on the side walls of the U-shaped air guide groove through bearings.

[0069] Referring to Figures 4 to 6 , as a specific embodiment of the papermaking net electrostatic removal packaging equipment provided by the present application, the impeller comprises a wheel shaft, a plurality of blades and an adjusting ring.

[0070] The wheel shaft is parallel to the supporting roller; the plurality of blades are distributed around the wheel shaft and are respectively hinged to the wheel shaft; and the adjusting ring is arranged around the wheel shaft and is respectively connected to each blade and adapted to rotate relative to the wheel shaft to drive the outer edges of each blade to approach or move away from the wheel shaft.

[0071] In the embodiment, the blades can be adjusted by rotating the adjusting ring, the rotating speed of the impeller under the same airflow and the resistance to the airflow are changed, so that the actual production situation can be adjusted.

[0072] In a specific implementation, the wheel shaft is arranged transversely in the airflow channel, and the two ends of the wheel shaft are mounted on the side walls of the airflow channel through bearings. Each blade is hingedly connected to the wheel shaft, so that the outer edge of each blade can be close to or away from the wheel shaft, thereby increasing or reducing the wind area of the blade. Each blade is in the shape of a long strip along the axis of the wheel shaft, and the total length of the blade is as close as possible to the transverse width of the airflow channel, so that the airflow in the airflow channel can act on the blade to the greatest extent. More specifically, two groups of blades and a rotating knock structure are arranged on the wheel shaft, and the rotating knock structure is located in the middle of the wheel shaft, and the two groups of blades are respectively located at the two end portions of the wheel shaft.

[0073] Referring to Figure 4 , as a specific implementation of the papermaking net electrostatic elimination packaging equipment provided in the present application, one or more rotating knock structures are arranged on the wheel shaft of the impeller, and the plurality of rotating knock structures are distributed at intervals along the wheel shaft.

[0074] In the present embodiment, for a relatively narrow papermaking net, one rotating knock structure can be arranged; for a relatively wide papermaking net, a plurality of rotating knock structures are arranged on the wheel shaft of the impeller, so that each part of the papermaking net can be knocked.

[0075] In a specific implementation, the single rotating knock structure is arranged at the middle position of the wheel shaft of the impeller; and the plurality of rotating knock structures are uniformly distributed on the wheel shaft of the impeller.

[0076] Referring to Figure 7 , as a specific implementation of the papermaking net electrostatic elimination packaging equipment provided in the present application, the rotating knock structure comprises a plurality of knock heads and a force storage stopper.

[0077] The plurality of knock heads are distributed around the wheel shaft and are respectively connected to the wheel shaft through elastic sheets; and the force storage stopper is opposite to the plurality of knock heads and is adapted to block the knock heads when the wheel shaft rotates, so that the elastic sheets are bent to store force, and after the knock heads move away from the force storage stopper, the elastic sheets are straightened and the knock heads knock the tensioned section.

[0078] In the present embodiment, the plurality of knock heads are connected to the wheel shaft of the impeller through the elastic sheets, so that the impeller can directly drive the knock heads to continuously knock the tensioned section when the impeller rotates. The force storage stopper can block the knock heads when the impeller rotates, so that the elastic sheets are bent to store force for the knock heads.

[0079] In a specific implementation, the knock heads can be made of resin plates or rubber plates to prevent scratching the papermaking net. The elasticity of the elastic sheets should be moderate, and the size of the elasticity should ensure that the knock heads can cause strong vibration of the papermaking net, and prevent the knock heads from scratching the papermaking net.

[0080] Referring to Figure 7As a specific embodiment of the papermaking net static electricity removing packaging device provided in the present application, the force storage stopper is a stopper plate with a groove edge extending inward.

[0081] In the present embodiment, the force storage stopper is formed by welding a stopper plate on the front edge or the rear edge of the air flow channel groove.

[0082] Please refer to Figures 8 to 10 As a specific embodiment of the papermaking net static electricity removing packaging device provided in the present application, the rotating push structure comprises two mounting plates and a plurality of push components.

[0083] The two mounting plates are mounted on the wheel shaft and form a mounting space in the middle, and each of the two mounting plates is provided with a plurality of radial guide grooves distributed around the wheel shaft, and the radial guide grooves on the two mounting plates are oppositely arranged.

[0084] The plurality of push components are arranged around the wheel shaft; each push component comprises a sliding piece and a push piece, both ends of the sliding piece are slidingly arranged in the corresponding radial guide grooves of the two mounting plates, the push piece is connected to the sliding piece, and the outer end is elastic and extends out of the outer periphery of the mounting space to contact and push the tensioning section.

[0085] The sliding pieces of adjacent push components are connected by a tension spring, which pulls each sliding piece radially inward to separate the outer end of the push piece from the tensioning section.

[0086] Both ends of the sliding piece of each push component are connected with a counterweight, so that when the rotation reaches a predetermined speed, the sliding piece is driven to slide radially outward against the tension of the tension spring, so that the outer end of the push piece restores contact with the tensioning section.

[0087] In the present embodiment, when the air permeability of the papermaking net is high, the impeller speed is low, at this time, the tension spring pulls the sliding piece radially inward, so that the outer end of the push piece is completely separated from the tensioning section, completely avoiding the push piece scratching the papermaking net, so that the winding speed of the papermaking net can be as high as possible. When the air permeability of the papermaking net is low, the impeller speed is high, at this time, the counterweight drives the sliding piece to slide radially outward against the tension of the tension spring under the action of centrifugal force, so that the outer end of the push piece restores contact with the tensioning section, so that the tensioning section can be pushed; moreover, the lower the air permeability of the papermaking net, the higher the impeller speed, and the greater the contact pressure between the outer end of the push piece and the tensioning section, so that the tensioning section can be better pushed, and the cleaning of dust and other impurities is more thorough.

[0088] In the embodiment, the radial direction refers to the diameter direction of the impeller shaft, the radial inward direction refers to the direction close to the impeller shaft, and the radial outward direction refers to the direction away from the impeller shaft. In the specific implementation, the two mounting plates are circular plates and are coaxially fixed on the shaft of the impeller. A plurality of radial guide grooves are arranged on the two mounting plates in a radial direction of the shaft. The two ends of the sliding member slide along the radial guide grooves of the two mounting plates through the sliding blocks. The actuating piece is fixed on the outer side of the sliding member. The actuating piece can be an elastic steel sheet, and the outer end of the elastic steel sheet can be wrapped with a rubber sleeve to prevent scratching the papermaking net.

[0089] Since the sliding members are distributed around the shaft and are arranged to slide in the radial direction, after the tension spring is connected between the two adjacent sliding members, the tension spring pulls the two sliding members inward in the radial direction. The tension spring can be located on the outer side of the two mounting plates or between the two mounting plates. Preferably, the tension spring is arranged between the corresponding end portions of the two adjacent sliding members to ensure that the pulling forces of the two ends of the sliding member are balanced, and the tension springs at the two ends of the sliding member are located on the outer side of the corresponding mounting plate to avoid hindering the sliding of the sliding member.

[0090] In order to increase the centrifugal force of the sliding member to resist the pulling force of the tension spring, a counterweight is arranged at each end of the sliding member, so that the weight of the counterweight can be controlled to control the predetermined rotating speed of the impeller at which the actuating piece starts to pop and stretch the stretching section, that is, the degree of the air permeability of the papermaking net at which the actuating piece starts to pop and stretch the stretching section.

[0091] Please refer to Figures 8 to 10 , as a specific embodiment of the papermaking net static electricity removing packaging device provided by the present application, the outer end of the actuating piece is curved away from the rotating direction of the impeller, and the tail end of the outer end of the actuating piece is curved towards the inner side of the outer end of the actuating piece, so as to avoid the contact between the tail end of the outer end of the actuating piece and the stretching section. The outer side of the outer end of the actuating piece is provided with a protrusion which is suitable for popping and stretching the stretching section.

[0092] In the embodiment, the protrusion on the outer side of the outer end of the actuating piece increases the friction with the stretching section, so that the actuating piece can better pop and stretch the stretching section when the outer end of the actuating piece sweeps across the stretching section. The tail end of the outer end of the actuating piece is curved towards the inner side of the outer end of the actuating piece, so as to avoid the contact between the tail end of the outer end of the actuating piece and the stretching section, and prevent the outer end of the actuating piece from scratching the stretching section when the outer end of the actuating piece sweeps across the stretching section.

[0093] In the specific implementation, the actuating piece is curved from an elastic steel sheet, and the edge is polished smooth. The inner end of the actuating piece is fixed with the sliding member, the outer end is curved away from the rotating direction of the impeller, and the tail end of the outer end is further curved towards the inner side of the outer end of the actuating piece. One or more protrusions are arranged on the outer side of the outer end of the actuating piece, and the protrusions can be made of rubber.

[0094] Please refer to Figure 2As a specific embodiment of the papermaking net static electricity removing packaging equipment provided in the application, the rear side of the upper negative pressure dust suction port is hingedly connected with a wind baffle, the lower end of the wind baffle is provided with a conductive adhesive tape matched with the tensioning section, so as to seal the rear side of the upper negative pressure dust suction port; the wind baffle presses down the tensioning section, and the wind baffle has a constant pressing force through the elastic member, so that the tensioning section maintains a constant tensioning force.

[0095] In the embodiment, the wind baffle can seal the rear side of the upper negative pressure dust suction port on one hand, so that the suction force of the upper negative pressure dust suction port is transmitted forward; on the other hand, the wind baffle can press down the tensioning section, so that the tensioning force of the tensioning section is more stable, and the vibration of the front dust removing assembly does not cause the tensioning force of the papermaking net to fluctuate too much, thereby affecting the winding effect of the net winding roller. The conductive adhesive tape at the lower end of the wind baffle is in contact with the tensioning section, so that new static electricity is avoided due to friction.

[0096] In the specific implementation, a tension spring can be arranged between the rear side plate of the upper negative pressure dust suction port and the wind baffle as the elastic member, so that the pressing force of the wind baffle is kept constant.

[0097] Please refer to Figure 2 As a specific embodiment of the papermaking net static electricity removing packaging equipment provided in the application, the upper negative pressure dust suction port is further provided with a booster plate, the booster plate is detachably arranged below the tensioning section and extends from the lower side of the upper negative pressure dust suction port to the lower side of the impeller, so that the negative pressure of the upper negative pressure dust suction port is conducted to the impeller.

[0098] In the embodiment, the booster plate is added, so that the suction force of the upper negative pressure dust suction port can be better conducted to the impeller in front, and the rotating speed of the impeller is increased. When the rotating speed of the impeller is too high, the booster plate can be removed, so that the rotating speed of the impeller is reduced.

[0099] In the specific implementation, the booster plate can be detachably fixed by bolts. The booster plate extends from the lower side of the upper negative pressure dust suction port to the lower negative pressure dust suction port. The booster plate can be arranged in an inclined shape with the front being lower and the rear being higher.

[0100] The above is only a preferred embodiment of the application, and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
