Description

Technical Field

[0001] This utility model relates to conveying equipment, and more specifically to an environmentally friendly idler roller conveyor line. Background Technology

[0002] In industrial settings such as chemical and metallurgical processing, idler conveyor lines, as core equipment for continuous material transport, have long faced the severe challenge of corrosive liquid corrosion. In high-humidity, high-acid environments, corrosive liquids adhering to the belt flow along both sides to the idlers. Similarly, in metallurgical pyrometallurgical or hydrometallurgical processes, acidic or alkaline solutions carried by wet materials overflow from the belt sides, both leading to continuous contact between the idlers and corrosive liquids. This directly causes accelerated corrosion and wear on the idler surface, leading to jamming, breakage, and other malfunctions, significantly shortening their service life. This not only necessitates frequent shutdowns to replace idlers, disrupting continuous production rhythms, but also severely restricts production efficiency due to soaring equipment wear and maintenance costs.

[0003] The safety and environmental problems caused by liquid leaks are equally serious. Corrosive liquids dripping from idler rollers make workshop floors slippery, significantly increasing the risk of workers slipping and falling. In metallurgical settings, the rotational inertia of idler rollers can also throw liquids into the surrounding area, corroding precision components such as instruments and electrical equipment, and even burning operators. At the same time, the unorganized discharge of these liquids containing acids, alkalis, and heavy metals will pollute soil, air, and water sources, violating environmental regulations and posing a long-term threat to the workshop environment and personnel health, becoming a hidden danger that urgently needs to be eliminated in the production site.

[0004] The combination of these issues makes the separation of wet and dry materials in idler conveyor lines a critical challenge that the industry must overcome. Whether from the perspective of ensuring stable equipment operation and reducing production costs, or from the perspective of eliminating safety hazards and meeting environmental requirements, developing efficient and reliable wet and dry separation technology is of paramount necessity and urgency, and is a vital support for promoting safe, efficient, and green production in industries such as chemical and metallurgy. Utility Model Content

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] An environmentally friendly idler conveyor line includes a frame on which a plurality of idlers are arranged at intervals, and a conveyor belt. The bottom of the conveyor belt is in contact with the idlers. Flexible absorbent sleeves are fitted at both ends of the idlers and are located below the conveyor belt. Liquid guide grooves are respectively provided on both sides of the frame and below the absorbent sleeves. The liquid guide grooves extend along the arrangement direction of the idlers. A plurality of extrusion components corresponding one-to-one with the absorbent sleeves are provided in the liquid guide grooves, and the absorbent sleeves abut against the extrusion components.

[0007] The present invention is further configured such that: the idler roller includes a rotating shaft, the two ends of the rotating shaft are respectively rotatably connected to the frame, a roller is sleeved on the rotating shaft, and the bottom of the conveyor belt is in contact with the roller.

[0008] The present invention is further configured such that: annular grooves are respectively provided at both ends of the roller, the annular grooves are formed around the circumference of the roller's sidewall, and the water-absorbing sleeve is fitted inside the annular grooves.

[0009] The present invention is further configured such that: the extrusion assembly includes an adjustment part fixed in the liquid guiding groove, and an extrusion head is threadedly connected to the adjustment part. The extrusion head moves vertically on the adjustment part. When the roller rotates, the water-absorbing sleeve abuts against the extrusion head to squeeze out the liquid.

[0010] The present invention is further configured such that the adjusting part is fixed to the liquid guiding groove by welding or by fasteners.

[0011] The present invention is further configured such that: there is a gap between the annular groove and the end of the roller, and the width of the liquid guiding groove is greater than the sum of the width of the annular groove and the distance from the end of the roller to the annular groove.

[0012] The present invention is further configured such that: the rotating shaft is made of metal material, and the roller is made of stone or polymer plastic.

[0013] The present invention is further configured such that: the absorbent sleeve is a sponge ring, and the inner ring of the sponge ring is provided with a fiber pad layer for anti-slip.

[0014] The present invention is further configured such that: the absorbent sleeve is a sponge strip, and each end of the sponge strip is provided with a mutually cooperating Velcro fastener, and the two ends of the sponge strip are connected by the Velcro fastener to form a ring.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. The water-absorbing sleeves at both ends of the idler roller can directly intercept the liquid flowing down from both sides of the conveyor belt, preventing the liquid from flowing down the idler roller and causing overall corrosion, extending the service life of the idler roller, reducing equipment maintenance downtime, and ensuring continuous production. When the idler roller rotates, the squeezing component comes into contact with the water-absorbing sleeve to squeeze out the liquid, realizing the recycling of the water-absorbing material, and collecting it together with the liquid dripping from the end of the idler roller into the liquid guide groove, realizing centralized guidance and liquid collection, preventing the liquid from dripping randomly, and reasonably separating dry and wet, significantly improving the workshop environment and eliminating safety hazards.

[0017] 2. The water-absorbing sleeve is installed in the annular groove on the roller for positioning, which prevents the water-absorbing sleeve from shifting axially during the rotation of the roller, ensuring that the water-absorbing sleeve is always in the effective water-absorbing position under the conveyor belt, and ensuring stable and reliable water absorption effect.

[0018] 3. Conventional foam rings can only be fitted from the end of the roller inwards, which is cumbersome and does not meet the needs of large-scale installation. By using Velcro to connect the ends, it is easy to install and remove quickly without laborious installation, which greatly reduces maintenance difficulty and time cost. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] First embodiment:

[0027] An environmentally friendly idler roller conveyor line, such as Figures 1 to 3 As shown, the machine includes a frame 1, on which several idlers 2 are arranged at intervals, and a conveyor belt 3. The bottom of the conveyor belt 3 is in contact with the idlers 2. The conveyor belt 3 is driven by motors and active synchronous rollers at the beginning and end of the frame 1. The idlers 2 on the frame 1 play a supporting role. When the conveyor belt 3 is running, it drives the idlers 2 to rotate through friction.

[0028] Flexible absorbent sleeves 4 are fitted at both ends of the idler roller 2. The absorbent sleeves 4 are located below the conveyor belt 3, so that when the liquid flows from both sides of the conveyor belt 3 onto the idler roller 2 and flows towards the middle of the idler roller 2, it will pass through the absorbent sleeves 4 and be absorbed and intercepted by the absorbent sleeves 4. Only the very end of the idler roller 2 will come into contact with the liquid, thus avoiding overall corrosion.

[0029] Liquid guide grooves 5 are respectively provided on both sides of the frame 1 and below the absorbent sleeves 4. The liquid guide grooves 5 extend along the arrangement direction of the idler rollers 2. Some liquid will drip directly from the idler rollers 2 or the conveyor belt 3, and the liquid guide grooves 5 collect the dripping liquid. In addition, several extrusion components corresponding to the absorbent sleeves 4 are provided in the liquid guide grooves 5. The bottom of the absorbent sleeve 4 abuts against the extrusion components. When the idler rollers 2 rotate, the flexible absorbent sleeves 4 automatically squeeze against the extrusion components, squeezing out the liquid absorbed by the absorbent sleeves 4 and dripping it into the liquid guide grooves 5, so that the absorbent sleeves 4 can repeatedly absorb water for a long time and realize the recycling of the absorbent material.

[0030] The idler roller 2 includes a rotating shaft 201, with both ends of the shaft 201 passing through circular holes in the frame 1 and rotatably connected to the frame 1 via bushings. A roller 202 is fixedly mounted on the rotating shaft 201, and the roller 202 is coaxially arranged with the rotating shaft 201. The bottom of the conveyor belt 3 is in contact with the roller 202. The length of the rotating shaft 201 is greater than the length of the roller 202, so that there is a gap between the two ends of the roller 202 and the frame 1. The length of the roller 202 is greater than the width of the conveyor belt 3.

[0031] Annular grooves 7 are respectively opened at both ends of the roller 202. The annular grooves 7 are opened in a circle along the circumference of the side wall of the roller 202, and the water-absorbing sleeve 4 is fitted into the annular grooves 7. The water-absorbing sleeve 4 is positioned by the installation of the annular grooves 7 to prevent the water-absorbing sleeve 4 from axially shifting during the rotation of the idler roller 2, so as to ensure stable and reliable water absorption effect.

[0032] There is a gap between the annular groove 7 and the end of the roller 202, so that the absorbent sleeve 4 is located on the inner side below the conveyor belt 3, intercepting the liquid flowing towards the middle of the idler roller 2. The width of the liquid guide groove 5 is greater than the sum of the width of the annular groove 7 and the distance from the end of the idler roller 2 to the annular groove 7, so that the liquid dripping from the end of the idler roller 2 and the conveyor belt 3, as well as the liquid squeezed out from the absorbent sleeve 4, will all collect in the liquid guide groove 5, completely covering the dripping liquid and preventing it from flowing to the ground.

[0033] The extrusion assembly 6 includes an adjustment part 602 fixed within the liquid guiding groove 5. An extrusion head 601 is threadedly connected to the adjustment part 602. The extrusion head 601 moves vertically on the adjustment part 602, allowing its height to be adjusted to suit different leakage conditions. Specifically, the adjustment part 602 is tubular, with external threads on its peripheral sidewalls. The extrusion head 601 is fitted onto the adjustment part 602, and its inner wall has internal threads that mate with the external threads, achieving a threaded connection. The top of the extrusion head 601 is an arc surface, minimizing friction with the absorbent sleeve 4 while achieving extrusion, thus preventing jamming. In this embodiment, the extrusion head 601 faces directly below the absorbent sleeve 4, with the bottom of the absorbent sleeve 4 contacting the top of the extrusion head 601. The extrusion head 601 is adjusted until its top portion penetrates the annular groove 7 of the roller 202, causing the bottom of the absorbent sleeve 4 to be extruded.

[0034] In this embodiment, the adjustment part 602 is fixed to the liquid guiding groove 5 by welding. Alternatively, in other embodiments, the adjustment part 602 is fixed to the liquid guiding groove 5 by fasteners, and the bottom edge of the adjustment part 602 is fastened to the liquid guiding groove 5 by bolts.

[0035] In this embodiment, the shaft 201 is made of metal, and the roller 202 is made of stone, which improves the friction of the roller 202 and makes it more corrosion resistant. In other embodiments, the roller 202 may also be made of polymer plastic.

[0036] In this embodiment, the absorbent sleeve 4 is a high-density sponge ring. During installation, the sponge ring is fitted into the annular groove 7 of the roller 202 from the end of the roller 2. The inner ring of the sponge ring is also provided with a fiber pad for anti-slip, so as to prevent the sponge ring from slipping against the extrusion head 601 when the roller 202 rotates.

[0037] The working process of this embodiment is as follows:

[0038] The idler roller 2 is supported below the conveyor belt 3, and the bottom of the conveyor belt 3 contacts the drum 202. When the conveyor belt 3 runs, it drives the idler roller 2 to rotate together. When liquid flows from both sides of the conveyor belt 3 onto the drum 202, the liquid is absorbed and intercepted by the absorbent sleeve 4, preventing it from continuing to flow into the center of the drum 202 and avoiding corrosion of the drum 202. When the idler roller 2 rotates, the absorbent sleeve 4 and the extrusion assembly 6 squeeze each other, squeezing the absorbed liquid into the liquid guide groove 5, allowing the absorbent sleeve 4 to repeatedly absorb water. The dripping liquid flows along the liquid guide groove 5 and is collected uniformly at a designated location.

[0039] Second embodiment:

[0040] An environmentally friendly idler roller conveyor line, such as Figure 4As shown, the difference between this embodiment and the first embodiment is that the absorbent sleeve 4 in this embodiment is a sponge strip 8. Both ends of the sponge strip 8 are fixed with mutually cooperating Velcro fasteners, one end being the hook side 9 and the other end being the loop side 10. The Velcro fasteners completely cover the end section of the sponge strip 8, and the two ends of the sponge strip 8 are connected by the Velcro to form a ring, thus fitting onto the ring groove 7. This facilitates quick installation and disassembly, greatly reducing maintenance difficulty and time costs.

[0041] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
