Description

Technical Field

[0001] The invention relates to the technical field of plane cleaning devices, in particular to a reciprocating negative pressure cleaning device. Background Art

[0002] The plane cleaning device includes cleaning devices applied to various plane environments and equipment. Take the surface cleaning of the return belt 13 of the belt conveyor as an example: when the belt conveyor is running with materials, due to inertia and adhesion, some fine particles do not fall from the head roller 11 into the head funnel 10, but are gradually scattered on the ground behind the surface increasing roller 12 and the bottom parallel roller along with the return belt, generating accumulated materials 14, such as Figure 1 shown.

[0003] Since the space under the surface increasing roller 12 is small and the belt is often in continuous operation for a long time, it is very difficult for the workers to clean the pile of materials and there are serious safety hazards. If it is not cleaned in time, it will increase the wear of the belt, roller and surface increasing roller 12, and it is easy to cause the belt to deviate. At the same time, the dust on the ground seriously affects the environmental sanitation on site. In the past, in addition to manual material picking and cleaning, water flushing was also used to clean the pile of materials, which not only wasted water resources, but also caused corrosion of the steel structure corridor and increased the amount of sludge treated in the factory.

[0004] In order to completely solve the problem of material carrying on the return belt, it is necessary to install various types of belt cleaning devices on the head of the belt conveyor, and the traditional rotating roller brush cleaning device is one of them. The cleaning device consists of an outer shell 17 and two sets of external power roller brush cleaners 15 (the motor drives the reducer to drive the roller brush to rotate), and a scraper conveyor 16 under the roller brush. Its working principle is that the two sets of external power roller brush cleaners 15 rotate in the opposite direction to the return belt conveyor, and the fine particles and dust adhering to the surface of the belt are swept away by the friction between the brush body and the belt. The fine particles and dust that fall off the surface of the belt fall into the outer shell 17 of the device under the action of gravity, and are then transported to the head funnel 10 by the scraper conveyor. Its working principle is as follows Figure 2 shown.

[0005] This traditional rotary brush cleaning device has the following disadvantages:

[0006] 1. The effective contact area between the roller brush and the belt surface is small, and the cleaning efficiency is low: the bristles of the electric roller brush are distributed along the circumference. According to the existing conventional brush body diameter, during the cleaning process, the friction contact width between the bristles of an electric roller brush and the belt surface is only about 20mm-30mm.

[0007] 2. The contact between the bristles and the belt surface is discontinuous, and the entire surface cannot be thoroughly cleaned: the curved bristles on the roller brush always rub against the moving belt surface along the running direction of the belt. Even if the bristles are dense, there must be gaps between the curved bristles. Therefore, the roller brush cannot achieve a thorough cleaning of the entire surface of the return belt.

[0008] 3. It is not easy for an external power roller brush to achieve real-time and continuous adjustment of the distance between the bristles and the belt surface: Since the motor and reducer are usually fixed and heavy, the transmission device and the brush body cannot adjust their positions continuously in real time after the bristles are worn. Therefore, as the bristles wear, the contact area and friction between the bristles and the belt will gradually decrease, resulting in reduced cleaning effect or even failure.

[0009] 4. The electric roller brush cleaning device has only one cleaning mode and poor adaptability: the electric roller brush is a fixed product, and the bristle carrier is integrated with the central shaft, so the electric roller brush cleaner has only one cleaning mode, which is bristle friction. For the cleaning needs of different environments and different equipment, the traditional electric roller brush cleaning device has poor adaptability.

[0010] 5. After the brush body fails, the replacement of spare parts is complicated, time-consuming and labor-intensive: When the bristles are severely worn and fail, and spare parts need to be replaced, the transmission connection mechanism between the brush body and the reducer must be disassembled, and then the bearing supports at both ends must be removed, and the above operations must be repeated in reverse for installation, which is time-consuming and labor-intensive.

[0011] 6. The operating cost of traditional electric roller brush cleaning devices is high: when the bristles are severely worn and fail, the brush body (including the drive shaft) needs to be replaced as a whole, so the operating cost of traditional electric roller brush cleaning devices is high.

[0012] 7. Traditional electric roller brush cleaning devices are prone to dust pollution during the cleaning and transportation process: the fine particles and dust swept by the traditional electric roller brush cleaning device fall into the shell by gravity, and then the scraper conveys the accumulated materials to the belt funnel. The above process will generate a lot of dust, polluting the on-site environment. Summary of the invention

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The purpose of the present invention is to provide a reciprocating negative pressure cleaning device to solve the problems of poor cleaning effect, large dust on site, single cleaning type, difficult brush replacement, high operating cost, etc. existing in traditional rotating roller brush cleaning devices.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 3-12 As shown, this embodiment provides a reciprocating negative pressure cleaning device, including a cleaning plate, a linear motion mechanism, an integrated box and a negative pressure dust suction mechanism.

[0049] The cleaning plate includes a base 201 and a cleaning part 204 vertically mounted on the base 201, and the cleaning part 204 has a cleaning body. The cleaning part 204 is preferably in the form of a brush row, and more preferably in the form of multiple rows; the linear motion mechanism is used to drive the cleaning plate to do reciprocating linear motion, and the length direction of the brush row is preferably perpendicular to the linear motion direction; the integrated box is located below the cleaning plate, and the upper end of the integrated box has an opening; the negative pressure dust suction mechanism is connected to the integrated box to suck dust and particulate matter in the integrated box.

[0050] When in use, the linear motion mechanism drives the cleaning plate to reciprocate, and the cleaning body of the cleaning part 204 rubs back and forth on the surface to be cleaned, thereby sweeping away the attached particles and dust. The swept particles and dust are sucked into the integrated box under the action of the negative pressure dust suction mechanism, and finally leave the integrated box under the continuous suction of the negative pressure dust suction mechanism.

[0051] During the continuous reciprocating motion of the cleaning section 204, at the moment when the relative motion direction between the cleaning section 204 and the surface to be cleaned changes, the sweeping body suddenly moves in the opposite direction, and the bending direction of the sweeping body in the contact part changes accordingly. During this process, the sweeping body will rub against the surface to be cleaned in a disorderly manner, and the pressure of the sweeping body on the surface to be cleaned will also increase instantly. In the traditional rotating roller brush cleaning method, the roller brush and the surface to be cleaned always maintain a fixed relative motion direction. The contact angle and friction direction of the bristles with the surface to be cleaned remain unchanged, similar to continuous raking contact cleaning. Therefore, the reciprocating negative pressure cleaning device of this embodiment significantly improves the cleaning effect compared with the traditional rolling cleaning device. In addition, because the linear motion cleaning method of this embodiment can achieve the fitting friction contact between the entire surface of the sweeping body of the cleaning section 204 and the surface to be cleaned, compared with the traditional rotating roller brush cleaning method that can only achieve direct contact between a small part of the circumference of the brush body and the surface to be cleaned, this embodiment significantly improves the cleaning efficiency. In addition, this embodiment adopts a negative pressure suction method, and there is no dust pollution during the whole process.

[0052] Furthermore, in order to ensure that the sweeping body is always in effective contact with the surface to be cleaned, the cleaning plate of this embodiment also includes a spring 202. The base 201 of this embodiment includes a bottom plate and a housing shell fixed on the base, and a through groove is provided on the top of the housing shell. The spring 202 and the holder 203 are located in the housing shell, one end of the spring 202 abuts against the bottom plate, and the other end of the spring 202 abuts against the bottom end of the holder 203 for installing the cleaning part 204. There are limiting ribs on both sides of the bottom of the holder 203, and the limiting ribs are located in the housing shell and contact and limit with the inner top surface of the housing shell. The number of springs 202 in the housing shell corresponding to each brush row is preferably multiple and evenly spaced to form a spring group.

[0053] During initial installation, the contact pressure between the upper end of the sweeping body and the surface to be cleaned is adjusted by adjusting the height of the integrated box. At this time, the limiting retaining edge of the holder 203 is separated from the inner top surface of the housing shell, and the spring 202 is compressed. The elastic force generated by the compression and deformation of the spring 202 supports the weight of the holder and the cleaning part 204 itself, while ensuring that the cleaning part 204 produces a suitable pressing force on the surface to be cleaned. As the sweeping body wears, the sweeping body moves upward under the elastic potential energy of the spring 202, realizing the automatic and continuous pressing of the sweeping body on the surface to be cleaned. The traditional electric roller brush cleaner requires regular manual adjustment, which is not only time-consuming and labor-intensive, but also before each adjustment, as the bristles wear, the cleaning effect is gradually reduced. The electric adjustment by installing a pressure sensor is not only complex in structure, but also poor in use. It should be noted that there are many ways to adjust the height of the integrated box. This embodiment uses the method of installing an adjustment foot 232 at the bottom of the integrated box to adjust the height. Those skilled in the art may also use other adjustment methods.

[0054] Furthermore, in order to improve the replacement efficiency and reduce the operation cost, the cleaning part 204 of this embodiment includes a cleaning body, a cleaning seat and a baffle 205, and the cleaning body is fixed on the cleaning seat. The limiting baffle is located at the bottom of the holder 203, and the top of the holder 203 is provided with a dovetail groove. The bottom of the cleaning seat of the cleaning part 204 is provided with a dovetail-shaped protrusion consistent with the shape of the dovetail groove, and the dovetail-shaped protrusion is arranged in the dovetail groove. Two baffles 205 are respectively detachably fixed to the two ends of the holder 203, or detachably fixed to the two ends of the cleaning seat, and the baffle 205 at least blocks a part of the dovetail groove.

[0055] When the bristles of a conventional electric roller brush cleaning device are severely worn and become ineffective, the entire device (including the transmission shaft) needs to be replaced, so the operating cost of the conventional electric roller brush cleaning device is high. However, in this embodiment, it is only necessary to remove the baffle 205, extract the ineffective cleaning part 204, insert the new cleaning part 204, and install the baffle 205, which can reduce the operating cost by 70% and improve the replacement efficiency.

[0056] Due to the different materials of the surface to be cleaned or the differences in the characteristics of the substances to be cleaned, bristles are not the most ideal cleaning material in some cases. The roller brush of the traditional electric roller brush cleaner is a stereotyped product, and the bristle carrier is integrated with the central axis, so bristles can only be used as the only cleaning type. In this embodiment, the cleaning section 204 is one row or multiple rows, and the type of the sweeping body in the cleaning section 204 can be a combination of one or more of a nylon brush 237, a wire brush 238, a nylon scraper brush 239, a rubber scraper brush 240, and a polyurethane scraper brush 241. As long as the dovetail protrusion at the bottom of the cleaning section 204 can be installed in conjunction with the dovetail groove on the base 203, it can be used.

[0057] There are many types of linear motion mechanisms in the prior art, such as screw slider linear motion mechanisms, crank slider linear motion mechanisms, etc. In this embodiment, a driving method in which a rack 216 and an incomplete gear 217 cooperate with each other is adopted. Specifically, the linear motion mechanism of this embodiment includes a driving mechanism and a reciprocating motion mechanism, and the reciprocating motion mechanism includes a rotating shaft 210, a bearing seat 212, an incomplete gear 217, a slide 211 and a slide rail, and the driving mechanism is used to drive the rotating shaft 210 to rotate. The rotating shaft 210 is mounted on the bearing seat 212, and the incomplete gear 217 is fixed on the rotating shaft 210. The slide box 209 includes a slide 211, a connecting plate, a rack 216 and a pulley 222. The two slides 211 are located opposite to each other, and the two ends of the two slides 211 are fixedly connected by a connecting plate. The base 201 is fixed on the slide box 209, and a transverse strip groove for the rotating shaft 210 to pass through is provided on the slide 211. Two racks 216 are fixed inside the carriage 211 and are respectively located on the upper and lower sides of the rotating shaft 210. The incomplete gear 217 is used to mesh with the rack 216. The incomplete gear 217 is only meshed with one rack 216 at the same time. The pulley 222 includes an upper pulley and a lower pulley. The pulley 222 is rotatably connected to the front and rear sides of the sliding box 209. The slide rail includes an upper slide rail 227 and a lower slide rail 225. The upper pulley is in rolling contact with the lower edge of the upper slide rail 227, and the lower pulley is in rolling contact with the upper edge of the lower slide rail 225.

[0058] The rotating shaft 210 and the incomplete gear 217 on the rotating shaft 210 rotate under the drive mechanism, and drive the rack 216 and the slide box 209 to move. When the incomplete gear 217 is engaged with the upper rack 216, the slide box 209 is driven to move linearly in a certain direction. When the incomplete gear 217 is engaged with the lower rack 216, the slide box 209 is driven to move linearly in the opposite direction, thereby realizing the reciprocating linear motion of the cleaning part 204. Compared with other linear drive methods, the linear motion mechanism of this embodiment is simpler, does not require electronically controlled reversing, and has a low failure rate.

[0059] In order to further improve the cleaning effect, there are two reciprocating motion mechanisms in this embodiment, and the sliding boxes 209 of the two reciprocating motion mechanisms move in opposite directions.

[0060] There are many types of driving mechanisms, as long as they can drive the rotating shaft 210 to rotate. In this embodiment, the driving mechanism includes a motor 206, a reducer 215, a coupling 207, a sprocket 208 and a chain 214. The output end of the motor 206 is fixedly connected to the input end of the reducer 215, and the output end of the reducer 215 is fixedly connected to one of the rotating shafts 210 through the coupling 207. A sprocket 208 is fixed on each of the two rotating shafts 210, and the two sprockets 208 are connected by a chain 214.

[0061] When the incomplete gear 217 of one reciprocating mechanism meshes with the adjacent rack 216 on the upper side, the incomplete gear 217 of the other reciprocating mechanism meshes with the adjacent rack 216 on the lower side, thereby achieving the opposite movement directions of the slide boxes 209 of the two reciprocating mechanisms in this embodiment.

[0062] Since the meshing part between the rack 216 and the incomplete gear 217 needs glycerin lubrication and it is necessary to ensure that no dust or fine materials enter, the present embodiment also includes a sealing mechanism, which includes a baffle 213, a sealing end cover 220, an upper slide 218, a lower slide 221, a slide pad 236, an annular felt pad seal 235, an outer baffle felt pad 219 and an inner baffle felt pad 234. The rotating shaft 210 passes through the sealing end cover 220 and the annular felt pad seal 235, the sealing end cover 220 is fixed to the baffle 213 by fasteners, and the annular felt pad seal 235 is clamped between the sealing end cover 220 and the baffle 213. The upper slide 218 and the lower slide 221 are fixed to the front and rear sides of each slide 211 by fasteners, and the slide pad 236 is clamped between the upper slide 218 and the slide 211 and between the lower slide 221 and the slide 211. A set of slide box 209 mechanism has two upper slide grooves 218 and two lower slide grooves 221, and the overall cross section of the four slide grooves is rectangular and distributed at four right angles. The outer felt pad 219 of the baffle is clamped between the baffle 213 and the upper slide groove 218 and between the baffle 213 and the lower slide groove 221, and the outer felt pad 219 of the baffle is pasted on the upper slide groove 218 and the lower slide groove 221. The inner felt pad 234 of the baffle is clamped between the baffle 213 and the slide 211, and the inner felt pad 234 of the baffle is pasted on the slide 211 and the upper slide groove 218 and the slide 211 and the lower slide groove 221 at the same time. The outer felt pad 219 of the baffle and the inner felt pad 234 of the baffle are both pasted and sealed with strong glue.

[0063] When the carriage 211 slowly performs reciprocating linear motion, the position of the rotating shaft 210 remains unchanged, the outer felt pad 219 of the baffle plate and the inner felt pad 234 of the baffle plate move synchronously with the carriage 211, and always keep close contact with the baffle plate 213, and the annular felt pad sealing ring 235 always keeps close contact with the rotating shaft 210 to achieve contact sealing. There are two reciprocating motion mechanisms in this embodiment, and each reciprocating motion mechanism is provided with a sealing mechanism.

[0064] In this embodiment, the bearing seats 212 are fixed to the upper end of the integrated box by fasteners. The slide rails are covered with slide rail pressure plates 226, which are distributed at intervals according to the moving range of the pulley 222 installed on the slide box 209. The slide rail pressure plates 226 are fixed to the integrated box by fasteners, and the slide rails and the slide rail pressure plates 226 form a running slideway for the lower pulley 222.

[0065] In this embodiment, the area on the integrated box body that is opposite to the sliding range of the sliding box 209 is open, and the area on the integrated box body outside the area that is opposite to the sliding range of the sliding box 209 is covered with a cover plate 233. The upper partition 229, the lower partition 230, the connecting plate and the electric star-shaped ash discharge valve 224 are installed inside the integrated box body, and the upper partition 229 and the lower partition 230 are connected by the connecting plate. The inside of the integrated box body is composed of a closed upper cavity, a connecting channel and an expanded lower cavity from top to bottom, and the electric star-shaped ash discharge valve 224 is located at the connecting channel. The integrated box body of this embodiment is welded with steel plates, and the upper partition 229 and the lower partition 230 are also welded to the integrated box body.

[0066] The space inside the integrated box is divided into an upper part and a lower part by an upper partition 229, a lower partition 230 and an electric star-shaped ash discharge valve 224, and a cover plate 233 is installed on the upper part of the integrated box, which can increase the negative pressure of the space to ensure that the fine particles can be fully sucked out.

[0067] Corresponding to the structure of the above-mentioned integrated box, the negative pressure dust suction mechanism in this embodiment includes an upper dust suction mechanism and a lower dust suction mechanism. The upper dust suction mechanism includes an upper cavity dust removal pipe 228 and a dust suction exhaust pipe 223, and the lower dust suction mechanism includes a lower cavity dust removal pipe 231.
