Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to an electrolyte heavy-duty scraper conveyor. Background Technology

[0002] In the production processes of metallurgical industries such as electrolytic aluminum, waste electrolytes generated are crushed and then transferred and recycled via scraper conveyors. Scraper conveyors are commonly used for this task due to their suitability for handling high temperatures, large dust levels, corrosive materials, and the need for enclosed transport. However, the crushed electrolyte material is characterized by high temperature, strong abrasiveness, and sharp particle edges, posing a severe challenge to the conveying equipment. Traditional scraper conveyors use solid scrapers, which experience solid sliding friction with the material as a whole when pushing it, resulting in huge operating resistance, high energy consumption, and extremely rapid wear of the scrapers and bottom plates, leading to short equipment lifespan, frequent maintenance, and high costs. Furthermore, although the equipment has a sealed structure, there is still a risk of dust emission at the loading and unloading ports due to material impact and airflow disturbance within the tank, polluting the environment and endangering personnel health. Therefore, there is an urgent need for a heavy-duty scraper conveyor that can significantly reduce wear, decrease operating resistance, and further suppress dust emission to adapt to the harsh working conditions of electrolyte transport. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heavy-duty scraper conveyor for electrolytes, which can solve the key problems of high wear, high resistance, easy blockage and dust emission in electrolyte conveying.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty scraper conveyor for electrolytes, comprising a head section, a middle section, a tail section, and a scraper chain. The middle section is a closed metal shell formed by a conveying trough and a dust cover. The scraper chain is located within the middle section and surrounds the head and tail sections. The scraper chain includes two chains, multiple scrapers, and multiple internal angle screws. The multiple scrapers are spaced apart between the two chains by the internal angle screws. Each scraper includes a scraper body and two connecting seats fixed at both ends. The scraper body has arc-shaped grooves extending along its length on two scraping surfaces along its length, and the arc-shaped grooves are narrower at the top and wider at the bottom in the longitudinal direction. The connecting seats are connected to the chains by longitudinally arranged internal angle screws, wherein the internal angle screws are threadedly engaged with the chains and slidably engaged with the connecting seats.

[0005] Preferably, it also includes a plurality of buffer members corresponding to the internal angle screw; the buffer members are sleeved on the internal angle screw and located between the head of the internal angle screw and the connecting seat.

[0006] Preferably, the buffer is a disc spring.

[0007] Preferably, the scraper has an inverted Z-shaped structure.

[0008] Preferably, the buffer element is made of silicon manganese spring steel or chromium vanadium spring steel.

[0009] Preferably, the connecting seat has a weight-reducing hole.

[0010] Preferably, the dust cover is composed of a front side panel, a rear side panel, a left side panel, a right side panel, and a top panel, wherein the front side panel and the rear side panel are both inclined, so that the dust cover has an overall cover-like structure that is wider at the top and narrower at the bottom.

[0011] Preferably, both the left and right side panels are provided with inspection ports, and the inspection ports are equipped with sealing doors.

[0012] Preferably, the dust cover further includes multiple connecting rods; the multiple connecting rods are fixedly and spaced apart between the front side plate and the rear side plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The electrolyte heavy-duty scraper conveyor provided in this application has a longitudinal arc-shaped groove with a narrow upper part and a wide lower part opened on the scraper body. This structure provides an upward flow channel for materials, so that some materials can flow into the arc-shaped groove and roll upward during the scraper's advancement. This effectively transforms the solid sliding friction between harmful materials and scrapers into rolling friction within the materials, greatly reducing the forward resistance and driving energy consumption of the scraper, and extending the service life of the scraper and the base plate. 2. The elastic connection mechanism between the connecting seat and the chain, consisting of internal angle screws and buffer components, can effectively absorb the instantaneous impact load on the scraper during operation, alleviate the rigid vibration and noise caused by the impact of material particles, provide protection for the scraper chain system, and further improve the reliability and durability of the equipment. 3. The dust cover adopts an inclined side plate design that is wider at the top and narrower at the bottom, which expands the space volume at the top of the conveying channel, which is conducive to the settling and backflow of dust, significantly improves the inherent dust reduction capacity of the equipment, effectively suppresses the phenomenon of dust overflowing from the feed port and discharge port, and improves the working environment.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0017] See Figure 1-4 In one embodiment of this utility model, an electrolyte heavy-duty scraper conveyor mainly consists of a head section 1, a middle section, a tail section 3, and a scraper chain. The head section 1 serves as the power source for the entire machine, equipped with a motor, reducer, hydraulic coupling, sprockets, bearings, connecting shafts, and other transmission components, providing the power required for system operation. The middle section is enclosed by a conveying trough 2 and a dust cover 4, forming a closed material conveying channel. The tail section 3 is equipped with sprockets, bearings, and connecting shafts, primarily serving a supporting and guiding function to ensure the smooth operation of the scraper chain. The scraper chain is arranged inside the middle section and surrounds the head section 1 and the tail section 3. This scraper conveyor also has a feed port and a discharge port, with the feed port corresponding to the tail section 3 and the discharge port corresponding to the head section 1. Through the coordinated drive of the head and tail sprockets, the scraper chain can achieve cyclical movement, thereby conveying materials from the tail to the head.

[0018] In this embodiment, the middle section is a closed metal shell, which can effectively prevent dust from escaping during material conveying and meet the requirements of clean production; see reference Figure 1-3 The dust cover 4 is a cover-like structure composed of a front side plate, a rear side plate, a left side plate, a right side plate, and a top plate. Both the front and rear side plates are inclined, giving the dust cover 4 a structure that is wider at the top and narrower at the bottom. This structure helps to expand the upper space of the channel, promote dust settling, and inhibit dust escape from the feed inlet and discharge outlet. Multiple spaced connecting rods are also fixed between the front and rear side plates to improve the stability of the dust cover 4 structure.

[0019] Furthermore, both the left and right side panels are equipped with inspection ports and openable sealed doors to facilitate equipment maintenance and repair.

[0020] The scraper chain includes a chain 5, scrapers 6, internal angle screws 7, and buffers 8. Multiple scrapers 6, internal angle screws 7, and buffers 8 are provided, and the buffers 8 are arranged correspondingly to the internal angle screws 7. There are two chains 5, and multiple scrapers 6 are installed between the two chains 5 at a certain interval through internal angle screws 7. Under the drive of the chains 5, the scrapers 6 can slide in contact with the bottom plate of the conveying trough 2 to achieve sliding scraping of materials.

[0021] The scraper 6 has an inverted Z-shaped structure, including a scraper body 61 and two connecting seats 62, with the two connecting seats 62 respectively fixed at both ends of the scraper body 61 along its length. Traditional scrapers generate solid-state friction with the material when pushing it, resulting in significant resistance. This is especially true for crushed electrolytes, whose particles are hard, angular, and highly abrasive, causing considerable wear on the scraper and reducing the equipment's lifespan. Therefore, in this embodiment, arc-shaped grooves are formed on both sides of the scraper body 61 along its length. These grooves are narrower at the top and wider at the bottom in the longitudinal section, giving the scraper body 61 an overall cross-section that is narrower at the bottom and wider at the top. This design effectively reduces the actual contact area between the scraper and the bottom of the groove, significantly reducing frictional resistance and wear.

[0022] In addition, the arc-shaped trough provides an upward flow guide channel for the material. During the scraper's advancement, some material surges upward along the arc-shaped trough and rolls, disrupting the overall solid-state flow of the material and inducing internal eddies and disturbances, forming a "micro-stirring" effect. This effect can prevent material compaction and agglomeration, reduce the risk of blockage, and improve conveying efficiency. At the same time, the continuous flow and renewal of the material also gives the scraper a self-cleaning function, reducing the adhesion of fine powder.

[0023] Furthermore, the connecting seat 62 is mounted on the chain 5 via an internal angle screw 7. The internal angle screw 7 is longitudinally positioned and threadedly connected to the chain 5, while the connecting seat 62 and the internal angle screw 7 are slidably connected. The buffer 8 is sleeved on the internal angle screw 7 and located between the head of the internal angle screw 7 and the connecting seat 62, serving as a buffer to mitigate the instantaneous rigid impact between the material and the scraper, further reducing wear and extending the equipment's service life. The connecting seat 62 has a through-hole for weight reduction, which reduces energy consumption by decreasing the weight of the scraper 6.

[0024] In this embodiment, the buffer 8 can be a disc spring, preferably made of 60Si2MnA (silicon manganese spring steel) or 50CrVA (chromium vanadium spring steel) to provide a stable and reliable buffering force.

[0025] In summary, the electrolyte heavy-duty scraper conveyor provided in this application utilizes a longitudinal, narrow-at-the-top, wide-at-the-bottom arc-shaped groove on the scraper body. This structure provides an upward flow channel for materials, allowing some material to surge into the arc-shaped groove and roll upwards during scraper advancement. This effectively transforms the solid sliding friction between harmful materials and the scraper into rolling friction within the material, significantly reducing the forward resistance and driving energy consumption of the scraper. Simultaneously, this internal tumbling of the material generates a "micro-stirring" effect, effectively preventing material compaction and agglomeration, avoiding blockage of the conveying channel, and ensuring smooth conveying. Furthermore, the continuous flow and renewal of materials within the arc-shaped groove also provides a self-cleaning effect on the scraper surface, reducing the deposition of adhesive fine powder materials on the scraper and extending the service life of the scraper and base plate. The elastic connection mechanism between the connecting seat and the chain, consisting of internal angle screws and buffer components, effectively absorbs the instantaneous impact load on the scraper during operation, mitigating rigid vibration and noise caused by material particle impact, protecting the scraper chain system, and further improving the reliability and durability of the equipment. In addition, the dust cover adopts an inclined side plate design that is wider at the top and narrower at the bottom, which expands the space volume at the top of the conveying channel, which is conducive to the settling and backflow of dust, significantly improves the inherent dust reduction capacity of the equipment, effectively suppresses the phenomenon of dust overflowing from the feed port and discharge port, and improves the working environment.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
