Abstract
Description
Technical Field
[0001] The utility model belongs to the field of conveying devices, and particularly refers to a water-cooled spiral conveying device. Background Art
[0002] The recycling of waste batteries refers to the reuse of used batteries through recycling. The most commonly used industrial batteries in China are lead-acid batteries, and lead accounts for more than 50% of the total cost of the battery. The main processes include pyrometallurgy, hydrometallurgy, and solid-phase electrolytic reduction technology. The outer shell is made of plastic, which can also be recycled to achieve no secondary pollution. Since the plastic outer shell of the collected waste batteries is attached with dust, sediment, oil stains, etc., these impurities affect the quality of the recycled plastic. In the prior art, the waste plastic is crushed and then conveyed to a cleaning tank for cleaning. Since the settling chamber of the crusher has a relatively small space, the heat cannot be discharged in time after the plastic is over-crushed, resulting in the crushed plastic being sticky and difficult to discharge. How to make the crushed plastic be discharged normally and be cleaned and conveyed at the same time. Summary of the Invention
[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a water-cooled spiral conveying device.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A water-cooled spiral conveying device includes a bracket, a feeding device fixedly connected to the bracket, and a spiral conveying device communicated with the feeding device. The spiral conveying device includes an inclined conveying pipe, and a spiral shaft is arranged in the conveying pipe. The two ends of the spiral shaft are respectively fixedly connected to a first connecting shaft and a second connecting shaft. The other end of the first connecting shaft extends out of the conveying pipe and is connected to a first bearing, and the other end of the second connecting shaft extends out of the conveying pipe and is connected to a second bearing. An inlet is arranged at the upper end of the conveying pipe, and an outlet is arranged at the lower end of the conveying pipe. A runner is fixedly connected to the second connecting shaft, and the runner is arranged opposite to the outlet. A filter element is arranged in the outlet.
[0005] In this solution, the inlet is connected to a water tank and cooling water is input through an electric pump. The cooling water flows through the conveying pipe and then flows out from the outlet, and the water flowing out from the outlet returns to the water tank to realize the recycling of water resources. By setting the first connecting shaft and the second connecting shaft, it is convenient to install and disassemble the spiral shaft. A runner is fixedly connected to the second connecting shaft, and the runner rotates with the spiral shaft to prevent the crushed plastic from depositing and blocking the space of the settling chamber. Here, the space of the settling chamber is the space between the feeding device and the spiral conveying device where they are communicated. When the crushed plastic falls down, it will be cooled by the cooling water, and after being stirred by the runner, the spiral shaft can better convey the crushed plastic.
[0006] Furthermore, the spiral shaft has a through middle through-hole. The two ends of the spiral shaft are respectively sleeved with a first connecting shaft and a second connecting shaft and fixed by fixing members. This solution can better reduce the weight of the spiral shaft. The spiral shaft includes a main shaft and spiral blades, where the spiral blades are welded and fixed to the main shaft to form the spiral shaft, and the main shaft is hollow. The first connecting shaft and the second connecting shaft are respectively embedded at the two ends of the spiral shaft and fixed by fixing members. The fixing members are preferably bolts or screws. This not only reduces the weight but also facilitates installation and later maintenance and disassembly.
[0007] Furthermore, a end cover is welded and fixed to the lower end of the conveying pipe. One end of the second connecting shaft extends out of the end cover and is connected to the second bearing. A seal is provided between the second connecting shaft and the end cover. The second connecting shaft also has a first ring, and there is a gap between the first ring and the end cover. A runner is fixedly connected to the end of the first ring away from the end cover.
[0008] Furthermore, the second connecting shaft also includes a second ring. The two ends of the spiral shaft have fixed rings. The second ring and the fixed ring are fixed by fixing members. The runner is located between the first ring and the second ring. By arranging the runner between the first ring and the second ring, and also at the inner end of the water outlet and opposite to the water outlet, it can better prevent the crushed plastics at the bottom from blocking, making the water outlet drain more smoothly.
[0009] Furthermore, a filter sleeve is fixedly sleeved on the end cover. The filter sleeve is also located between the conveying pipe and the runner. The height of the filter sleeve is higher than the height of the runner. The filter sleeve covers the water outlet. The filter element can be a filter net and is arranged inside the pipe wall of the water outlet. Here, the filter element is preferably a filter sleeve. Setting the filter sleeve can reduce the accumulation of crushed plastics at the water outlet and make the drainage more smooth.
[0010] Furthermore, the feeding device includes a hopper. A blade assembly is fixedly connected below the hopper. Below the blade assembly is the discharge port. One end of the conveying pipe close to the second connecting shaft has a feeding port. The discharge port is communicated with the feeding port.
[0011] Furthermore, the discharge port is fixedly connected by three bent plates and one straight plate. The straight plate is located on the side close to the end cover. The lower part of the spiral shaft is arranged opposite to the discharge port. The setting of the three bent plates and one straight plate can better prevent the accumulation of crushed plastics, and through the cooperation of the spiral shaft and the runner, the crushed plastics can be conveyed more smoothly.
[0012] Furthermore, the conveying pipe includes a pipe cover and a pipe body that are hermetically fixed. The separately arranged conveying pipe is convenient for later maintenance.
[0013] Compared with the prior art, the technical effect of the present utility model is as follows: the discharge port in the feeding device is set as a three-sided bent plate and a one-sided flat plate, which is not easy to accumulate; the spiral shaft and the runner cooperate with each other, and cooling water is used to cool the residual temperature after crushing, so that it can be better transported in the conveying pipeline; the spiral shaft can not only convey but also increase the contact stroke with water by its spiral shape to clean the crushed plastics; the crushed plastics can not only be better discharged, but also be cleaned and conveyed at the same time.
