A novel non-powered conveying device

Abstract

This utility model relates to a novel non-powered conveying device, comprising a first support unit, a second support unit, several rolling units, and a collection unit. Its advantages lie in that the first, second, and third support units provide stable support for the rolling units. Through the rotational structure of the rolling units themselves, the waste refrigerators slide relative to each other using gravity, thus conveying the waste refrigerators forward. No additional power unit is required, saving energy. Furthermore, the collection unit collects dust and exhaust fumes generated during the movement of the waste refrigerators in real time, providing a safe and healthy working environment.

Description

Technical Field

[0001] This utility model relates to the field of non-powered roller conveyor technology, and in particular to a novel non-powered conveying device for conveying refrigerators on a waste refrigerator dismantling line. Background Technology

[0002] As bulky waste, the recycling and dismantling of used refrigerators is a crucial step in environmental protection and resource recycling. On a typical used refrigerator dismantling line, large, heavy, and potentially irregularly shaped used refrigerators need to be transported from one process to the next. Non-powered roller conveyor lines have been widely used in certain sections of dismantling lines (such as pre-treatment, temporary storage, and non-powered conveying areas) due to their simple structure, relatively low cost, convenient maintenance, and lack of need for an additional power source. However, existing non-powered roller or conveyor devices used in used refrigerator dismantling lines still present some technical challenges in practical application.

[0003] First, existing equipment lacks dust control devices, easily leading to dust pollution. During the dismantling and transportation of used refrigerators, dust and debris are typically generated. This dust not only pollutes the working environment and harms the health of operators, but may also affect the efficiency of subsequent processing steps and equipment performance. Existing non-powered roller conveyor systems usually lack effective dust collection or suppression measures.

[0004] Secondly, there are certain hidden dangers in the stability of the conveying process. Because discarded refrigerators are usually large in size and may have uneven bottoms or unstable center of gravity due to lack of support, the non-powered rollers in the existing technology often only provide rolling support at the bottom and lack effective lateral constraints and support for the refrigerators. It is difficult to ensure the stable conveying of tall and irregular objects, which makes it easy for the refrigerators to tilt or even tip over during the conveying process, thereby affecting the conveying efficiency and even posing a safety hazard to on-site personnel.

[0005] In addition, during the transportation of used refrigerators, some debris or liquid may fall out. Traditional non-powered conveying devices often do not have the function of collecting fallen debris or liquid, resulting in pollution of the ground. Alternatively, the collection device is fixedly connected to the roller frame, which is not only inconvenient to disassemble, but also cannot handle debris in a timely manner. As a result, liquid and debris (such as a mixture of dust and debris) accumulate and are difficult to clean or replace thoroughly. This not only affects the cleanliness of the site environment and increases the difficulty and time cost of maintenance, but also makes it inconvenient to collect and treat leaked oil.

[0006] There is still no effective solution to the problems of insufficient dust and exhaust gas control, poor conveying stability, and inconvenient collection and treatment of debris in existing technologies. Utility Model Content

[0173] How to use this utility model:

[0174] In use, the used refrigerator is placed on the roller element 32. Due to gravity, the used refrigerator exerts a downward pressure on the roller element 32. This pressure is decomposed into a component force along the conveying direction, causing the used refrigerator to move forward along the roller element 32. The roller element 32 rotates relative to the roller element 31. The dust and exhaust gas generated by the used refrigerator during the rolling process are collected by the collection element 41 and transported to the exhaust gas or dust treatment system for further processing via the output element 42.

[0175] The technical effects of this utility model are as follows:

[0176] The first, second, and third support units provide stable support for the rolling unit. The rolling unit rotates on its own, and the waste refrigerator slides relative to the rolling unit due to gravity, thus transporting the waste refrigerator forward. No additional power unit is required, saving energy. The collection unit collects the dust and exhaust gas generated during the movement of the waste refrigerator in real time, providing a safe and healthy working environment and solving the problem of insufficient control of dust and exhaust gas.

[0218] The third sliding element 63 is connected to the receiving element 61 by a fixed connection. The fixed connection method includes, but is not limited to, integral molding and welding.

[0219] The dimensions of the third sliding element 63 are matched with the dimensions of the first sliding element 14. Generally, the radial dimension (e.g., width, height) of the cross-section of the third sliding element 63 is smaller than the radial dimension (e.g., width, height) of the cross-section of the first sliding element 14 to which it is located.

[0220] Understandably, the shape of the third sliding element 63 matches the shape of the first sliding element 14 so that the third sliding element 63 can slide freely within the first sliding element 14.

[0250] The usage method of this embodiment is as follows:

Specifically, the connection between the first limiting element 67 and the second limiting element 68 is released, separating the sixth sliding element 66 from the fifth sliding element 65. Simultaneously, the storage element 62 can be directly removed using the method of Embodiment 2, or the usage method of Embodiment 3 can be used to slide and separate the fourth sliding element 64 from the second sliding element 25, allowing the storage element 62 to be removed for liquid treatment. Then, the storage element 62 can be reinstalled in the same manner.

[0252] The technical effects of this embodiment are as follows:

[0253] The storage element and the receiving element are designed to be separable, and the storage element can be disassembled separately through a sliding connection to process the debris or liquid stored inside. This makes the operation more flexible and convenient, and further solves the problem of inconvenient collection and processing of debris.

[0274] When installing the receiving element 61, first hold the holding element 74, connect the fourth limiting element 73 (second limiting block) to the third limiting element 72 (second limiting groove), so that the fourth limiting element 73 slides into the third limiting element 72. After the third sliding element 63 slides into the first sliding element 14, the fourth sliding element 64 slides into the second sliding element 25, and then slide the fourth limiting element 73 into the third limiting element 72, so that the fourth limiting element 73 protrudes and stops at the port of the first sliding element 14 or the port of the second sliding element 25.

[0275] During disassembly, first disconnect the fourth limiting element 73 from the third limiting element 72, so that the third sliding element 63 is separated from the first sliding element 14, and the fourth sliding element 64 is separated from the second sliding element 25, so that the receiving element 61 and the storage element 62 can be slid out.

[0276] The technical effects of this embodiment are as follows:

[0277] By using a limiting unit to stop the end of the receiving unit, it can not only effectively prevent the receiving unit from separating from the first support unit and the second support unit, but also rely on the weight of the limiting unit itself for stopping. The structure is simple and the operation is convenient.
