[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0047] like Figures 1 to 4 As shown, a first aspect of the present disclosure provides an aluminum hydroxide conveyor belt cleaning device 100, comprising: a spray assembly 110 for spraying cleaning fluid onto the return section 112' of the conveyor belt 110' of the conveyor 100'; a scraper assembly 120 disposed on one side of the spray assembly 110 for abutting against the return section 112', and arranged in the direction from the drive pulley 120' of the conveyor 100' to the driven pulley of the conveyor 100', the scraper assembly 120 being arranged between the spray assembly 110 and the driven pulley; and a roller brush assembly 130 disposed on one side of the scraper assembly 120 for abutting against the return section 112', and arranged in the direction from the drive pulley 120' to the driven pulley, the roller brush assembly 130 being arranged between the scraper assembly 120 and the driven pulley.

[0048] The aluminum hydroxide conveyor belt cleaning device 100 provided in this embodiment includes the aforementioned spray assembly 110, scraper assembly 120, and roller brush assembly 130. Based on the aforementioned configuration, the cleaning device 100 can sequentially clean the return section 112' of the conveyor belt 110' using the spray assembly 110, scraper assembly 120, and roller brush assembly 130 during the operation of the conveyor 100'. That is, the return section 112' of the conveyor belt 110' can sequentially pass through the aforementioned spray assembly 110, scraper assembly 120, and roller brush assembly 130 during the return motion. The component 130 is cleaned sequentially by the spray component 110, the scraper component 120, and the roller brush component 130. The cleaning operation does not need to be performed when the conveyor 100' is stopped, which helps to ensure the continuity of production operations, reduces the manual requirements for cleaning operations, improves the safety and efficiency of cleaning operations, and increases the frequency of cleaning operations. It is also convenient to carry out cleaning operations and material conveying operations simultaneously, which helps to clean the dirt adhering to the surface of the conveyor belt 110' in a timely manner and reduces the risk of damage to the conveyor belt 110' and the conveyor 100'.

[0049] Understandably, based on the aforementioned configuration, the scraper assembly 120 is located between the spray assembly 110 and the roller brush assembly 130. The spray assembly 110 can rinse the surface of the conveyor belt 110' by spraying cleaning fluid onto the return section 112', thereby at least partially removing dirt adhering to the surface of the conveyor belt 110' and suppressing powder flying around the conveyor belt 110' using the cleaning fluid; the scraper assembly 120 can scrape off at least part of the dirt and liquid from the surface of the conveyor belt 110' by sliding friction with the return section 112', improving the cleanliness and surface dryness of the conveyor belt 110'; the roller brush assembly 130 can scrape off at least part of the dirt and liquid from the surface of the conveyor belt 110' by sliding friction with the return section 112', improving the cleanliness and surface dryness of the conveyor belt 110'; the roller brush assembly 130 can... The rolling friction between the return sections 112' further removes at least some of the dirt and liquid from the surface of the conveyor belt 110', and further improves the cleanliness and surface dryness of the conveyor belt 110'. This allows the cleaned conveyor belt 110' to carry and transport aluminum hydroxide powder after it is converted from the return section 112' to the conveying section 111', avoiding the increase in the amount of dirt adhering to the conveyor belt 110' due to surface dampness, and reducing the risk of introducing contaminants into the aluminum hydroxide powder, which helps to ensure the purity of the material.

[0050] It is understood that the aforementioned conveyor 100' is a belt conveyor. Accordingly, the aforementioned conveyor 100' may include a drive pulley 120', a driven pulley, and a conveyor belt 110' drivingly connected between the aforementioned drive pulley 120' and the driven pulley. The aforementioned conveyor belt 110' may have a conveying section 111' and a return section 112' connected to each other. The aforementioned conveying section 111' is used to carry and transport materials, and the aforementioned materials may be, but are not limited to, aluminum hydroxide powder. The driving pulley 120' and the driven pulley are arranged at intervals, and their axes are coplanar. If the plane containing the axis of the driving pulley 120' and the axis of the driven pulley is taken as the interface, the conveying section 111' and the return section 112' are located on both sides of the interface. Correspondingly, if the conveyor belt 110' is divided into multiple belt segments along its length, each belt segment can cyclically switch between the conveying section 111' and the return section 112' during the operation of the conveyor belt 110'.

[0051] It is understandable that in practical applications, the aforementioned return section 112' is usually located below the conveying section 111' along the direction of gravity. Accordingly, the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 can all be located below the aforementioned return section 112' along the direction of gravity.

[0052] It is understood that the aforementioned roller brush assembly 130 may include a roller brush portion 131, the periphery of which abuts against the aforementioned return section 112', and the roller brush portion 131 can rotate around its own axis, thereby rolling against the aforementioned return section 112'. Accordingly, in practical applications, the axial direction of the roller brush portion 131 may be arranged to extend along the width direction of the conveyor belt 110', so as to increase the contact range between the roller brush portion 131 and the conveyor belt 110' and improve the cleaning effect of the roller brush portion 131 on the conveyor belt 110'.

[0053] It is understandable that the spray pressure of the aforementioned spray assembly 110 can be set according to actual needs, and no further restrictions are imposed here. However, it is not difficult to understand that the rinsing effect of the spray assembly 110 on the surface of the conveyor belt 110' will increase with the increase of spray pressure.

[0054] It is understandable that, in practical applications, the spraying range of the aforementioned spraying assembly 110 in the width direction of the aforementioned conveyor belt 110', the length of the aforementioned scraping assembly 120 in the width direction of the aforementioned conveyor belt 110', and the length of the aforementioned roller brush assembly 130 in the width direction of the aforementioned conveyor belt 110' can all be set in conjunction with the width of the conveyor belt 110'. For example, the aforementioned spraying range and length can be greater than or equal to the width of the conveyor belt 110', so as to improve the effective cleaning range of the spraying assembly 110, the scraping assembly 120, and the roller brush assembly 130, and avoid forming cleaning dead corners.

[0055] For example, when the width of the conveyor belt 110' is 1.8m, the length of the scraper assembly 120 in the width direction of the conveyor belt 110' and the length of the roller brush assembly 130 in the width direction of the conveyor belt 110' can both be 1.8m. The two ends of the scraper assembly 120 in the width direction of the conveyor belt 110' are respectively flush with the two ends of the conveyor belt 110' in the width direction, and the two ends of the roller brush assembly 130 in the width direction of the conveyor belt 110' are respectively flush with the two ends of the conveyor belt 110' in the width direction. At the same time, in the width direction of the conveyor belt 110', the spraying range of the spraying assembly 110 can be set to cover the width distribution range of the conveyor belt 110'.

[0056] It is understood that the aforementioned cleaning fluid may be, but is not limited to, water or liquid cleaning agents; the aforementioned contaminants may include, but are not limited to, material powders, dust, etc.

[0057] like Figure 1As shown, in some feasible examples, along the direction from the aforementioned driving pulley 120' to the aforementioned driven pulley, the aforementioned spray assembly 110 is arranged with the aforementioned driving pulley 120' at a preset interval distance. The aforementioned preset interval distance can be greater than or equal to 1.5m and less than or equal to 2.5m. For example, the aforementioned preset interval distance can be, but is not limited to, 1.8m, 2m, 2.2m, etc. Understandably, based on the aforementioned configuration, on the one hand, the distance between the spray assembly 110 and the drive pulley 120' can be avoided from being too close, thereby preventing the cleaning fluid output by the spray assembly 110 from affecting the operation of the drive pulley 120'; on the other hand, the distance between the spray assembly 110 and the drive pulley 120' can also be avoided from being too far, extending the distance between the spray assembly 110 and the driven pulley, thereby facilitating the faster cleaning of the conveyor belt 110' after it transitions to the return section 112', and providing relatively ample time and travel distance for the conveyor belt 110' to dry after passing through the spray assembly 110.

[0058] In some feasible examples, the aluminum hydroxide conveyor belt cleaning device 100 may also include a support assembly for fixed arrangement relative to the frame of the aforementioned conveyor 100', wherein the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 are disposed on the aforementioned frame; or, the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 are disposed on the frame of the conveyor 100'.

[0059] like Figure 2 As shown, in some examples, the spray assembly 110 includes: a liquid supply pipe 111 having an inlet 111a and a plurality of outlets, the inlet 111a being connected to a liquid supply device; a plurality of nozzle portions 112 connected to the outlets, each outlet corresponding to one nozzle portion 112, the plurality of nozzle portions 112 being arranged at intervals along the width direction of the conveyor belt 110'; wherein, the nozzle portions 112 are used to spray cleaning fluid onto the return section 112'.

[0060] In this technical solution, the spray assembly 110 may include the aforementioned liquid supply pipe 111 and a plurality of the aforementioned nozzle portions 112; based on the aforementioned configuration, the spray assembly 110 can use the plurality of nozzle portions 112 to spray cleaning liquid at different positions in the width direction of the conveyor belt 110', thereby increasing the spraying range of the spray assembly 110 in the width direction of the conveyor belt 110', so as to improve the effective cleaning range of the spray assembly 110 and avoid forming cleaning dead corners.

[0061] In some feasible examples, a plurality of the aforementioned nozzle portions 112 are arranged at equal intervals along a preset direction, the preset direction being used to match the width direction of the aforementioned conveyor belt 110'.

[0062] In some feasible examples, the number of the aforementioned nozzle sections 112 is greater than or equal to 5, for example, but not limited to 6, 8, 11, 15, etc.

[0063] In some feasible examples, the aforementioned nozzle section 112 includes a wear-resistant and corrosion-resistant nozzle.

[0064] In some feasible examples, the aforementioned nozzle section 112 includes a high-pressure nozzle.

[0065] like Figure 2 As shown, in some feasible examples, the aforementioned liquid supply pipe 111 includes a pipe body and a connecting flange. One end of the aforementioned pipe body forms the aforementioned liquid inlet 111a and is connected to the aforementioned connecting flange, while the other end is a closed end. The aforementioned liquid outlet is opened on the periphery of the pipe body, and the aforementioned connecting flange is used to connect to the output pipe of the aforementioned liquid supply device. Exemplarily, the diameter of the aforementioned pipe body can be greater than or equal to 20 mm and less than or equal to 30 mm, for example, it can be, but is not limited to, 22 mm, 25 mm, 28 mm, etc.

[0066] In some examples, the nozzle section 112 includes a hollow cone nozzle or a solid cone nozzle.

[0067] In this technical solution, the nozzle section 112 includes a hollow cone nozzle or a solid cone nozzle; based on the aforementioned configuration, the spray range of a single nozzle section 112 can be increased, thereby improving the cleaning range of the nozzle section 112 on the conveyor belt 110', reducing the cleaning dead angles of the spray assembly 110, and reducing the number of nozzle sections 112 used, thus reducing the manufacturing cost of the cleaning device.

[0068] It is understood that the aforementioned hollow cone nozzle is used to spray cleaning liquid mist that is distributed in a roughly hollow cone shape; the aforementioned solid cone nozzle is used to spray cleaning liquid mist that is distributed in a roughly solid cone shape.

[0069] like Figure 2 As shown, in some examples, the distance between two adjacent nozzle portions 112 is less than or equal to 150 mm; and / or the spray angle θ of the nozzle portion 112 is greater than or equal to 100° and less than or equal to 120°.

[0070] In this technical solution, the spacing between two adjacent nozzle sections 112 can be set to be less than or equal to 150mm along the arrangement direction of the multiple nozzle sections 112. Based on the aforementioned arrangement, the arrangement density of the nozzle sections 112 in the width direction of the conveyor belt 110' can be increased, thereby increasing the spraying range of the spray assembly 110 in the width direction of the conveyor belt 110', so as to improve the effective cleaning range of the spray assembly 110, avoid the formation of cleaning dead corners, and facilitate the superposition of the spraying ranges of multiple hollow cone nozzles or multiple solid cone nozzles, further improving the cleaning effect of the spray assembly 110 on the conveyor belt 110'.

[0071] In this technical solution, the spray angle θ of the nozzle section 112 can be set to be greater than or equal to 100° and less than or equal to 120°. It is understood that the aforementioned spray angle θ is used to characterize the cone angle of the cone-shaped liquid mist sprayed by the hollow cone nozzle or the solid cone nozzle. Based on the aforementioned setting, on the one hand, it can avoid the cone angle of the cone-shaped liquid mist sprayed by the hollow cone nozzle or the solid cone nozzle being too large, which is conducive to preventing the liquid mist distribution from being too dispersed, thereby facilitating the rinsing effect on the conveyor belt 110'. On the other hand, it can avoid the cone angle of the cone-shaped liquid mist sprayed by the hollow cone nozzle or the solid cone nozzle being too small, which is conducive to ensuring the spray area of ​​the nozzle section 112 and reducing the probability of the formation of rinsing dead corners.

[0072] It is understood that in this technical solution, while setting the interval between two adjacent nozzle sections 112 to be less than or equal to 150 mm, the spray angle θ of the nozzle section 112 can be set to be greater than or equal to 100° and less than or equal to 120°.

[0073] For example, the distance between two adjacent nozzle portions 112 can be, but is not limited to, 140mm, 120mm, 100mm, etc.

[0074] For example, the spray angle θ of the aforementioned nozzle portion 112 can be, but is not limited to, 105°, 110°, 115°, etc.

[0075] like Figure 1 As shown, in some feasible examples, the central axis of the spray nozzle of the aforementioned nozzle portion 112 is arranged obliquely relative to the thickness direction of the conveyor belt 110', so that the aforementioned central axis extends from the aforementioned spray nozzle towards the aforementioned drive pulley 120'. Exemplarily, the angle α between the aforementioned central axis and the thickness direction of the aforementioned conveyor belt 110' is greater than or equal to 0° and less than or equal to 60°. For example, the aforementioned angle α can be, but is not limited to, 40°, 45°, 50°, etc.

[0076] like Figure 1 and Figure 3 As shown, in some examples, the scraping assembly 120 includes a plurality of polyurethane scrapers 121 disposed between the spray assembly 110 and the roller brush assembly 130, the plurality of polyurethane scrapers 121 being spaced apart along the direction from the driving pulley 120' to the driven pulley, and the polyurethane scrapers 121 abutting against the return section 112'.

[0077] In this technical solution, the scraping assembly 120 may include a plurality of the aforementioned polyurethane scrapers 121. Based on the aforementioned configuration, on the one hand, the scraping assembly 120 can use the plurality of polyurethane scrapers 121 to scrape away at least part of the dirt and liquid on the surface of the conveyor belt 110', thereby improving the cleanliness and surface dryness of the conveyor belt 110'. On the other hand, the polyurethane scrapers 121 have good strength, hardness and wear resistance, thereby extending the service life of the scraping assembly 120 and ensuring the contact strength between the scraping assembly 120 and the conveyor belt 110', providing further assurance for the cleaning effect of the scraping assembly 120 on the conveyor belt 110'.

[0078] It is understood that the aforementioned polyurethane scraper 121 includes a polyurethane scraper plate, the thickness direction of which is arranged to extend approximately perpendicular to the thickness direction of the conveyor belt 110'.

[0079] like Figure 1 and Figure 4 As shown, in some examples, the brush assembly 130 includes: a brush portion 131, the peripheral side of which is used to abut against the return section 112', and the axial direction of the brush portion 131 is used to extend along the width direction of the conveyor belt 110'; and a drive portion 132, connected to the brush portion 131, for driving the brush portion 131 to rotate.

[0080] In this technical solution, the roller brush assembly 130 may include the aforementioned roller brush section 131 and the aforementioned drive section 132. Based on the aforementioned configuration, the roller brush assembly 130 can use the drive section 132 to provide power for the rotation of the roller brush section 131, so that the roller brush section 131 can roll against the return section 112', thereby improving the brushing efficiency of the roller brush section 131 on the conveyor belt 110' and providing further assurance for the cleaning effect of the roller brush assembly 130 on the conveyor belt 110'.

[0081] In some examples, the drive unit 132 includes a variable frequency motor, and the brush unit 131 is connected to the output shaft of the variable frequency motor.

[0082] In this technical solution, the drive unit 132 may include the aforementioned variable frequency motor; based on the aforementioned configuration, the rotation control flexibility of the roller brush unit 131 can be improved, thereby facilitating the adjustment of the cleaning efficiency of the roller brush assembly 130 on the conveyor belt 110' according to actual needs.

[0083] In some feasible examples, the drive unit 132 further includes a control unit, which includes an acquisition module and a control module. The acquisition module is used to acquire the running speed of the conveyor belt 110', and the control module is signal-connected to the acquisition module and the drive unit 132, and is used to control the output rotation speed of the drive unit 132 according to the running speed, so that the output rotation speed decreases as the running speed increases.

[0084] It is understandable that the relative speed between the conveyor belt 110' and the roller brush 131 is affected by the running speed of the conveyor belt 110' and the rotational speed of the roller brush 131. The higher the relative speed, the higher the cleaning efficiency of the roller brush 131 on the conveyor belt 110'. Therefore, when the running speed of the conveyor belt 110' is high, the relative speed is also high, which can reduce the output rotational speed of the drive unit 132 to reduce the rotational speed of the roller brush 131, so as to save energy consumption of the roller brush assembly 130 while ensuring the cleaning efficiency of the roller brush assembly 130. Conversely, when the running speed of the conveyor belt 110' is low, the relative speed is also low, which can increase the output rotational speed of the drive unit 132 to increase the rotational speed of the roller brush 131, so as to ensure the cleaning efficiency of the roller brush assembly 130.

[0085] like Figure 1 As shown, in some examples, the aluminum hydroxide conveyor belt cleaning device 100 further includes: a liquid collection assembly 140, which has a liquid inlet and a liquid collection tank connected to the liquid inlet; a spray assembly 110, a scraper assembly 120 and a roller brush assembly 130 are all arranged corresponding to the liquid inlet; wherein, in the projection plane perpendicular to the conduction direction of the liquid inlet, the orthographic projections of the spray assembly 110, the scraper assembly 120 and the roller brush assembly 130 are all located within the range of the orthographic projection of the liquid inlet.

[0086] In this technical solution, the aluminum hydroxide conveyor belt cleaning device 100 may also include the aforementioned liquid collection component 140; based on the aforementioned configuration, the cleaning device 100 can utilize the aforementioned liquid collection component 140 to recover the used cleaning liquid, so as to facilitate centralized treatment of the used cleaning liquid, improve the cleanliness of the production site, and reduce the difficulty of cleaning the production site.

[0087] It is understandable that, in practical applications, the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 can be positioned above the aforementioned liquid collection assembly 140 along the direction of gravity.

[0088] It is understood that the size of the aforementioned liquid inlet can be set in conjunction with the distribution range of the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 and / or the size specifications of the conveyor belt 110'; taking the width of the aforementioned conveyor belt 110' as an example, the length of the aforementioned liquid inlet in the width direction of the aforementioned conveyor belt 110' can be greater than or equal to 1.8m; taking the distribution range of the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 in the length direction of the conveyor belt 110' as an example, the length of the aforementioned liquid inlet in the length direction of the aforementioned conveyor belt 110' can be greater than or equal to 1.8m.

[0089] It is understood that the depth of the aforementioned liquid collection tank can be set according to actual needs. For example, the aforementioned depth can be greater than or equal to 0.3m, such as, but not limited to, 0.4m, 0.5m, 0.6m, etc.

[0090] For example, the aforementioned liquid collection tank may be generally frustum-shaped or generally conical, and the aforementioned liquid inlet is located at the end of the aforementioned liquid collection tank with a larger area along its axial direction.

[0091] like Figure 1 As shown, in some examples, the liquid collection assembly 140 includes: a receiving portion 141 having a drain port, a receiving port and a collection tank, the drain port being connected to the collection tank; and a connector 142 for connecting the drain port and the cleaning fluid treatment device.

[0092] In this technical solution, the liquid collection assembly 140 may include the aforementioned receiving portion 141 and the aforementioned connecting member 142. Based on the aforementioned configuration, on the one hand, it facilitates the discharge of liquid from the liquid collection tank, reduces the probability of liquid overflowing from the liquid collection tank through the liquid inlet, and helps to further ensure the cleanliness of the production site and reduce the difficulty of cleaning the production site; on the other hand, it can guide the used cleaning fluid to the cleaning fluid treatment device so that the cleaning fluid treatment device can treat the used cleaning fluid.

[0093] It is understood that the aforementioned connector 142 may include a short connector and a hose. The short connector is connected between the aforementioned hose and the aforementioned receiving portion 141 and is used to connect the aforementioned hose and the aforementioned drain port. The specifications of the aforementioned short connector can be selected in combination with the dimensions of the hose and the aforementioned drain port. For example, the aforementioned short connector may be a DN50 short connector.

[0094] It is understood that the aforementioned cleaning fluid treatment device may include a separation component, which is used to separate the aforementioned used cleaning fluid to separate aluminum hydroxide powder, other contaminants and residual liquid. The separated aluminum hydroxide powder can be transported back to the conveyor section 111' of the conveyor belt 110' for further transport, thereby reducing the loss of aluminum hydroxide powder during transportation.

[0095] like Figure 1As shown, a second aspect of the present disclosure provides an aluminum hydroxide conveying system, comprising: a conveyor 100', including a drive pulley 120', a driven pulley, and a conveyor belt 110' drivenly connected between the drive pulley 120' and the driven pulley; the conveyor belt 110' having a conveying section 111' and a return section 112' connected to each other; the conveying section 111' being used to carry the material to be conveyed; and an aluminum hydroxide conveyor belt cleaning device 100 as described in any of the first aspects above, wherein a spray assembly 110 is used to spray cleaning fluid onto the return section 112', and a scraper assembly 120 and a roller brush assembly 130 are both abutting against the return section 112'; wherein, along the direction from the drive pulley 120' to the driven pulley, the roller brush assembly 130 is arranged between the scraper assembly 120 and the driven pulley, and the spray assembly 110 is arranged between the scraper assembly 120 and the drive pulley 120'.

[0096] An aluminum hydroxide conveying system according to an embodiment of this disclosure includes the aforementioned conveyor 100' and an aluminum hydroxide conveyor belt cleaning device 100 as described in any of the first aspects above. Based on the aforementioned configuration, the cleaning device 100 can sequentially clean the return section 112' of the conveyor belt 110' using a spray assembly 110, a scraper assembly 120, and a roller brush assembly 130 during the operation of the conveyor 100'. That is, the return section 112' of the conveyor belt 110' can sequentially pass through the aforementioned spray assembly 110, scraper assembly 120, and roller brush assembly 130 during the return motion. The conveyor belt 110' and the roller brush assembly 130 are sequentially cleaned by the spray assembly 110, the scraper assembly 120 and the roller brush assembly 130. The cleaning operation does not need to be performed when the conveyor 100' is stopped, which helps to ensure the continuity of production operations, reduces the manual requirements of cleaning operations, improves the safety and efficiency of cleaning operations, and increases the frequency of cleaning operations. It is also convenient to carry out cleaning operations and material conveying operations simultaneously, which helps to clean the dirt adhering to the surface of the conveyor belt 110' in a timely manner and reduces the risk of damage to the conveyor belt 110' and the conveyor 100'.

[0097] Understandably, based on the aforementioned configuration, the scraper assembly 120 is located between the spray assembly 110 and the roller brush assembly 130. The spray assembly 110 can rinse the surface of the conveyor belt 110' by spraying cleaning fluid onto the return section 112', thereby at least partially removing dirt adhering to the surface of the conveyor belt 110' and suppressing powder flying around the conveyor belt 110' using the cleaning fluid; the scraper assembly 120 can scrape off at least part of the dirt and liquid from the surface of the conveyor belt 110' by sliding friction with the return section 112', improving the cleanliness and surface dryness of the conveyor belt 110'; the roller brush assembly 130 can scrape off at least part of the dirt and liquid from the surface of the conveyor belt 110' by sliding friction with the return section 112', improving the cleanliness and surface dryness of the conveyor belt 110'; the roller brush assembly 130 can... The rolling friction between the return sections 112' further removes at least some of the dirt and liquid from the surface of the conveyor belt 110', and further improves the cleanliness and surface dryness of the conveyor belt 110'. This allows the cleaned conveyor belt 110' to carry and transport aluminum hydroxide powder after it is converted from the return section 112' to the conveying section 111', avoiding the increase in the amount of dirt adhering to the conveyor belt 110' due to surface dampness, and reducing the risk of introducing contaminants into the aluminum hydroxide powder, which helps to ensure the purity of the material.

[0098] It is understood that the aforementioned conveyor 100' is a belt conveyor 100', and correspondingly, the aforementioned conveyor 100' may include a drive pulley 120', a driven pulley, and a conveyor belt 110' drivingly connected between the aforementioned drive pulley 120' and the driven pulley; the aforementioned conveyor belt 110' may have a conveying section 111' and a return section 112' connected to each other, the aforementioned conveying section 111' being used to carry and transport materials, the aforementioned materials being, but not limited to, aluminum hydroxide powder. Yes, the driving pulley 120' and the driven pulley are arranged at intervals, and their axes are coplanar. If the plane containing the axis of the driving pulley 120' and the axis of the driven pulley is taken as the interface, then the conveying section 111' and the return section 112' are located on both sides of the interface. Correspondingly, if the conveyor belt 110' is divided into multiple belt segments along its length, then during the operation of the conveyor belt 110', each belt segment can be cyclically transferred between the conveying section 111' and the return section 112'.

[0099] It is understandable that in practical applications, the aforementioned return section 112' is usually located below the conveying section 111' along the direction of gravity. Accordingly, the aforementioned spray assembly 110, scraper assembly 120 and roller brush assembly 130 can all be located below the aforementioned return section 112' along the direction of gravity.

[0100] It is understood that the aforementioned roller brush assembly 130 may include a roller brush portion 131, the periphery of which abuts against the aforementioned return section 112', and the roller brush portion 131 can rotate around its own axis, thereby rolling against the aforementioned return section 112'. Accordingly, in practical applications, the axial direction of the roller brush portion 131 may be arranged to extend along the width direction of the conveyor belt 110', so as to increase the contact range between the roller brush portion 131 and the conveyor belt 110' and improve the cleaning effect of the roller brush portion 131 on the conveyor belt 110'.

[0101] It is understandable that the spray pressure of the aforementioned spray assembly 110 can be set according to actual needs, and no further restrictions are imposed here. However, it is not difficult to understand that the rinsing effect of the spray assembly 110 on the surface of the conveyor belt 110' will increase with the increase of spray pressure.

[0102] It is understandable that, in practical applications, the spraying range of the aforementioned spraying assembly 110 in the width direction of the aforementioned conveyor belt 110', the length of the aforementioned scraping assembly 120 in the width direction of the aforementioned conveyor belt 110', and the length of the aforementioned roller brush assembly 130 in the width direction of the aforementioned conveyor belt 110' can all be set in conjunction with the width of the conveyor belt 110'. For example, the aforementioned spraying range and length can be greater than or equal to the width of the conveyor belt 110', so as to improve the effective cleaning range of the spraying assembly 110, the scraping assembly 120, and the roller brush assembly 130, and avoid forming cleaning dead corners.

[0103] For example, when the width of the conveyor belt 110' is 1.8m, the length of the scraper assembly 120 in the width direction of the conveyor belt 110' and the length of the roller brush assembly 130 in the width direction of the conveyor belt 110' can both be 1.8m. The two ends of the scraper assembly 120 in the width direction of the conveyor belt 110' are respectively flush with the two ends of the conveyor belt 110' in the width direction, and the two ends of the roller brush assembly 130 in the width direction of the conveyor belt 110' are respectively flush with the two ends of the conveyor belt 110' in the width direction. At the same time, in the width direction of the conveyor belt 110', the spraying range of the spraying assembly 110 can be set to cover the width distribution range of the conveyor belt 110'.

[0104] It is understood that the aforementioned cleaning fluid may be, but is not limited to, water or liquid cleaning agents; the aforementioned contaminants may include, but are not limited to, material powders, dust, etc.

[0105] In some feasible examples, the conveyor 100' may also include a tensioning wheel 130' that abuts against the return section 112'.

[0106] Furthermore, since the aluminum hydroxide conveying system proposed in this embodiment includes the aluminum hydroxide conveyor belt cleaning device 100 as described in any of the first aspects above, it possesses all the beneficial effects of the cleaning device 100, which will not be elaborated here.
