Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery recycling technology, and in particular relates to a washing device for recycling lead-acid battery casing materials. Background Technology

[0002] Lead-acid batteries are mostly made of PP or ABS materials. After the waste lead-acid battery casings are dismantled, the plastic casings are recycled. The plastic casings obtained from dismantling need to go through processes such as cleaning, crushing, and drying before they can be reused as recycled materials.

[0003] For example, Chinese utility model CN221734174U discloses a battery casing recycling and cleaning device. Through a spiral shaft and a cylinder sleeved around the spiral shaft, casing fragments and washing liquid are transported from the bottom of the cleaning tank to the top of the cylinder, and then overflow from the cylinder and fall back to the bottom of the cleaning tank, forming a cycle cleaning, which improves the thorough cleaning effect of casing fragments.

[0004] However, since the shell fragments can only move up and down inside the cleaning tank, and the turbidity of the cleaning solution inside the tank increases, the shell fragments are also affected by the dirty cleaning solution, resulting in a poor overall cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a lead-acid battery shell recycling and cleaning device, which uses a screw conveyor to transport shell fragments to a circular perforated plate and sprays them through nozzles, thus solving the problem of poor cleaning effect of existing shell fragments.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a washing device for recycled lead-acid battery casings, comprising a washing tank with a screw conveyor connected inside. The washing tank has a feed inlet on its side wall and a drain outlet on its bottom wall. A top cover is connected to the upper end of the washing tank, and a coil is fixedly connected to the inner top wall of the top cover. The coil is connected to evenly distributed nozzles and a water inlet pipe that penetrates the top cover. The screw conveyor includes a cylinder and a screw shaft located inside the cylinder. A circular perforated plate is fixedly connected to the outer wall of the cylinder and is fixedly connected to the washing tank. The circular perforated plate has a discharge outlet, and a discharge port is fixedly connected to the lower surface of the circular perforated plate. The discharge chute corresponds to the outlet position and penetrates the side wall of the washing tank. The upper end of the spiral shaft is rotatably connected to the top cover and is driven by a motor. The motor is fixedly connected to the top cover. Several material-pushing crossbars are fixedly connected to the upper end of the spiral shaft. Several inclined plates and a pusher plate are fixedly connected to the material-pushing crossbars. The inclined plates are inclined relative to the axial direction of the material-pushing crossbars. The spiral shaft drives the material-pushing crossbars to rotate, and the inclined plates push the material conveyed from the upper end of the spiral conveyor away from the spiral conveyor. The pusher plate is parallel to the axial direction of the material-pushing crossbars and is used to push the material into the outlet to achieve automatic discharge.

[0008] As a preferred embodiment of this utility model, the bottom wall of the cleaning tank is conical, which is used to gather the material towards the lower end of the screw conveyor.

[0009] As a preferred embodiment of this utility model, the cleaning tank and the top cover are provided with corresponding flange structures and are connected by bolts.

[0010] As a preferred technical solution of this utility model, the diameter of the circular perforated plate is larger than the inner diameter of the cleaning box, and it is provided with through holes corresponding to the bolts, which are used to clamp and fix the circular perforated plate when the cleaning box and the top cover are connected.

[0011] As a preferred technical solution of this utility model, a number of stirring crossbars are fixedly connected to the lower end of the spiral shaft, which are used to drive the stirring crossbars to rotate and to turn over the accumulated materials.

[0012] As a preferred embodiment of this utility model, the stirring crossbar is provided with a plurality of stirring support rods along the axial direction, which are used to improve the stirring effect through the stirring support rods.

[0013] This utility model has the following beneficial effects:

[0014] This invention features a spiral conveyor connected inside the cleaning tank and a coil connected to the inner top wall of the top cover. Battery casing fragments enter the cleaning tank for initial cleaning, and the spiral conveyor then transports the initially cleaned casing fragments to a circular perforated plate, where they are sprayed through nozzles on the coil for further cleaning. This process avoids contamination by the cleaning solution and effectively improves the overall cleaning effect.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Example 1

[0030] Please see Figures 1-3 As shown, this utility model is a washing device for recycled lead-acid battery casings, including a washing tank 1, which is supported and fixed by a bracket or support leg (not shown in the figure). A screw conveyor 2 is connected inside the washing tank 1, and a feed inlet 101 is provided on the side wall of the washing tank 1. Fragments of the battery casing are put into the washing tank 1 through the feed inlet 101.

[0031] like Figure 5 and 7 As shown, the bottom wall of the cleaning tank 1 is provided with a drain port 102, and the top end of the cleaning tank 1 is connected to a top cover 3. The cleaning tank 1 and the top cover 3 are provided with corresponding flange structures and are connected by bolts. The inner top wall of the top cover 3 is welded or fixedly connected to a coil 301 by means of a hoop, etc. The coil 301 is connected to evenly distributed nozzles, and the coil 301 is connected to a water inlet pipe 302, which passes through the top cover 3. The water inlet pipe 302 is connected to the pump body through a pipe, and the pump body injects cleaning fluid into the coil 301, which is then sprayed out by the nozzles.

[0032] like Figures 4-6As shown in Figure 8, the screw conveyor 2 includes a cylinder 201 and a screw shaft 202 located inside the cylinder 201. A circular perforated plate 203 is welded or bolted to the outer wall of the cylinder 201, and the circular perforated plate 203 is fixedly connected to the cleaning tank 1. Taking the arrangement in the attached figure as an example, the diameter of the circular perforated plate 203 is larger than the inner diameter of the cleaning tank 1, and it has through holes corresponding to the bolts connecting the cleaning tank 1 and the top cover 3. During installation, the circular perforated plate 203 is supported on the flange structure of the cleaning tank 1, and then the top cover 3 is placed on the upper surface of the circular perforated plate 203. When the cleaning tank 1 and the top cover 3 are connected by bolts, the bolts pass through the through holes of the circular perforated plate 203. After the bolts are tightened, the circular perforated plate 203 is clamped and fixed by the cleaning tank 1 and the top cover 3.

[0033] The circular perforated plate 203 has a discharge port 204 near the inner wall of the cleaning tank 1, and the lower surface of the circular perforated plate 203 is welded or screwed with a discharge chute 205 corresponding to the position of the discharge port 204. The side wall of the cleaning tank 1 has a slot corresponding to the position of the discharge chute 205, and the discharge chute 205 penetrates the side wall of the cleaning tank 1 through the slot.

[0034] The upper end of the spiral shaft 202 is rotatably connected to the top cover 3 and is connected to a motor 4. The motor 4 is fixedly connected to the top cover 3. Two material-pushing crossbars 206 are fixedly connected to the upper end of the spiral shaft 202. Several inclined plates 207 and a pusher plate 208 are fixedly connected to the material-pushing crossbars 206. The number of inclined plates 207 can be flexibly set according to the length of the material-pushing crossbars 206. In this embodiment, three are shown in the attached figure as an example. The three inclined plates 207 are all located between the pusher plate 208 and the spiral shaft 202 and are evenly distributed. When the spiral shaft 202 rotates, the rotation path of the pusher plate 208 passes through the discharge port 204.

[0035] During cleaning, the shell fragments entering the cleaning tank 1 are initially cleaned by the cleaning fluid in the cleaning tank 1. The liquid level of the cleaning fluid in the cleaning tank 1 is not higher than the circular orifice plate 203, and the cleaning fluid can be discharged through the drain port 102 to control the liquid level of the cleaning fluid in the cleaning tank 1.

[0036] Shell fragments are conveyed upwards by the screw conveyor 2, discharged from the upper port of the cylinder 201, and accumulate on the circular perforated plate 203. The inclined plate 207 is axially inclined relative to the feeding crossbar 206. As the screw shaft 202 rotates, it drives the feeding crossbar 206 to rotate, using the inclined plate 207 to push the shell fragments conveyed from the upper end of the screw conveyor 2 away from the screw conveyor 2. Simultaneously, cleaning fluid is sprayed from the nozzles to further clean the shell fragments, preventing them from being affected by contaminated cleaning fluid and effectively improving the overall cleaning effect.

[0037] During the rotation of the pusher plate 208 driven by the spiral shaft 202, the pusher plate 208 and the pusher bar 206 are arranged parallel to each other in the axial direction. The pusher plate 208 pushes the shell fragments along the circumferential direction. When the fragments are pushed to the outlet 204, they are pushed into the outlet 204. The fragments fall into the discharge chute 205 through the outlet 204 and are discharged from the cleaning box 1 through the discharge chute 205, thus achieving automatic discharge and further improving the overall production efficiency.

[0038] Example 2

[0039] like Figure 2 and 4 As shown, based on Embodiment 1, the bottom wall of the cleaning tank 1 is tapered, which is used to gather the shell fragments toward the lower end of the screw conveyor 2, thereby facilitating the screw conveyor 2 to transport the shell fragments.

[0040] Meanwhile, at least one stirring crossbar 209 is fixedly connected to the lower end of the spiral shaft 202, as shown in the attached figure. The stirring crossbar 209 is used to rotate through the spiral shaft 202, and the stirring crossbar 209 is used to turn over the shell fragments accumulated at the bottom of the cleaning tank 1, thereby achieving the effect of stirring and cleaning, and facilitating the gradual rolling and gathering of materials towards the lower end of the spiral conveyor device 2.

[0041] Meanwhile, the stirring crossbar 209 is provided with several stirring support rods 210 along the axial direction, forming a comb-like structure, which facilitates better movement of the shell fragments at the bottom of the cleaning tank 1, thereby improving the stirring effect through the stirring support rods 210 and further enhancing the initial cleaning effect.
