[0004] However, the patent with application number 202411183986.0 states that during the battery breakage process, gases such as hydrogen fluoride in the electrolyte will directly volatilize into the surrounding environment, causing serious harm to human health and the environment.
[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention
[0006] The purpose of this invention is to provide an electrolyte collection device for waste batteries that can effectively solve the above-mentioned technical problems.
[0007] To achieve the objectives of this invention, the following technical solution is adopted: An electrolyte collection device for waste batteries includes a crushing mechanism for crushing the batteries and an adsorption mechanism for adsorbing gases. The crushing mechanism includes a fixed cylinder and a spiral crushing blade rotatably installed inside the fixed cylinder. The spiral crushing blade is connected to a drive motor to drive its rotation to crush the waste batteries inside the fixed cylinder. The adsorption mechanism includes a first rotating seat, a second rotating seat, and a plurality of adsorption cylinders installed between the first rotating seat and the second rotating seat; the first rotating seat and the second rotating seat are rotatably mounted on the outside of the fixed cylinder; The first rotating seat is connected to the drive motor via a drive assembly to drive it to rotate, thereby causing the adsorption cylinder to rotate and adsorb the volatile gas.
[0008] Furthermore, the drive assembly includes a main gear, a synchronous belt connecting the drive motor and the main gear, and a sprocket meshing with the main gear. The sprocket is fixedly connected to the first rotating seat. The drive motor drives the main gear to rotate via the synchronous belt, thereby causing the sprocket and the first rotating seat to rotate.
[0009] Furthermore, a fixing block is provided on both the first rotating seat and the second rotating seat, and a positioning block is installed at the end of the adsorption cylinder. The fixing block and the positioning block are fixed together by locking bolts.
[0010] Furthermore, a waste liquid collection box and a waste material collection box are provided below the fixed cylinder.

[0015] Furthermore, a push rod is fixedly installed on the vibrating filter screen. Both the first and second rotating seats are provided with several protrusions that roll in contact with the push rod. The rotation of the first and second rotating seats drives the protrusions to rotate, causing the protrusions to push the push rod, which in turn drives the vibrating filter screen to reciprocate and vibrate. Furthermore, the contact surface between the push rod and the protrusion is an arc-shaped surface.

[0017] 2. In the electrolyte collection device for waste batteries of the present invention, the rotation of the first rotating seat and the second rotating seat simultaneously drives the vibrating filter to reciprocate, thereby accelerating the separation of battery fragments from electrolyte and allowing the battery fragments and electrolyte to enter the corresponding waste collection box and waste liquid collection box, realizing the classified collection of battery fragments and electrolyte for convenient subsequent processing.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0029] like Figures 1 to 6 As shown, the electrolyte collection device for waste batteries of the present invention includes: a crushing mechanism 100 for crushing the batteries and an adsorption mechanism 200 for adsorbing the gas; the waste batteries enter the crushing mechanism 100 and are crushed, and the gas generated in the process is adsorbed by the adsorption mechanism 200 to prevent it from volatilizing into the environment and causing harm to human body and environment.
[0030] The crushing mechanism 100 includes a fixed cylinder 101 and a spiral crushing blade 105 rotatably installed inside the fixed cylinder 101. The spiral crushing blade 105 is connected to a drive motor 300, and the drive motor 300 drives the spiral crushing blade 105 to rotate and crush the waste batteries inside the fixed cylinder 101. The drive motor 300 is mounted on a frame 400.
[0031] The fixed cylinder 101 has an inlet 102 and an outlet 103. Waste batteries are fed into the fixed cylinder 101 through the inlet 102, and then crushed by the spiral shredder 105. The crushed battery fragments and electrolyte are then discharged through the outlet 103. In addition, a waste liquid collection tank 500 and a waste material collection tank 600 are provided at the outlet 103 to collect electrolyte and battery fragments.
[0032] It should also be noted that the fixed cylinder 101 includes a crushing section and a discharge section. The crushing section and the discharge section are fixedly connected by a flange. The feed inlet 102 is installed on the crushing section, and the discharge outlet 103 is installed on the discharge section. The adsorption mechanism 200 is installed on the crushing section. By setting the fixed cylinder 101 as the crushing section and the discharge section, it is convenient to install or replace the adsorption mechanism 200.
[0033] The adsorption mechanism 200 includes a first rotating seat 201, a second rotating seat 202, and a plurality of adsorption cylinders 203 installed between the first rotating seat 201 and the second rotating seat 202. The first rotating seat 201 is connected to the drive shaft of the drive motor 300 through a drive assembly. When the drive motor 300 drives the spiral pulverizer 105 to rotate, it drives the first rotating seat 201 to rotate and causes the surrounding air to flow, thereby drawing the volatile gas discharged from the discharge port 103 of the fixed cylinder 101 into the adsorption cylinder 203 to prevent it from volatilizing into the surrounding environment.
[0034] Both the first rotating seat 201 and the second rotating seat 202 are rotatably connected to the fixed cylinder 101. Specifically, the fixed cylinder 101 is provided with a positioning boss 104, and the first rotating seat 201 and the second rotating seat 202 are threadedly connected to the corresponding positioning boss 104, which facilitates the installation of the first rotating seat 201 and the second rotating seat 202. The positioning boss 104 is rotatably connected to the fixed cylinder 101 through a rotating bearing, so that the first rotating seat 201 and the second rotating seat 202 can rotate relative to the fixed cylinder 101.
[0035] A fixing block 204 is provided on both the first rotating seat 201 and the second rotating seat 202. The fixing block 204 is U-shaped. A positioning block 205 is installed on the end of the adsorption cylinder 203. Positioning holes are provided on both the fixing block 204 and the positioning block 205. A locking bolt 206 is inserted into the positioning hole. The adsorption cylinder 203 is fixed between the first rotating seat 201 and the second rotating seat 202 by the locking bolt 206. This allows the first rotating seat 201 to rotate, which in turn drives the adsorption cylinder 203 and the second rotating seat 202 to rotate, so as to adsorb the volatile gas. It also facilitates the installation or replacement of the adsorption cylinder 203.
[0036] It should be further noted that the adsorption cylinder 203 is filled with adsorption material, specifically one or a combination of activated carbon, molecular sieves, or silica gel. These adsorption materials all have excellent adsorption properties and can effectively adsorb gases such as hydrogen fluoride volatilized from the electrolyte, preventing them from being directly released into the surrounding environment and causing harm to human health and the environment.
[0037] The drive assembly includes a timing belt 207, a main gear 208, and a spur gear 209. Timing pulleys are mounted on the drive shaft of the drive motor 300 and the rotating shaft of the main gear 208. The timing belt 207 is sleeved on the outside of the timing pulleys. The spur gear 209 meshes with the main gear 208 and is fixedly connected to the first rotating seat 201. The drive motor 300 drives the main gear 208 to rotate via the timing pulleys and timing belt 207, thereby driving the spur gear 209 to rotate the first rotating seat 201, which in turn drives the adsorption cylinder 203 to rotate and adsorb the volatile gases.
[0038] By setting the first rotating seat 201 and the second rotating seat 202 to drive the adsorption cylinder 203 to rotate and adsorb the gas, the contact area between the adsorption cylinder 203 and the volatile gas can be increased, improving the adsorption efficiency and allowing the gas to be adsorbed more fully. At the same time, this rotational adsorption method can make the adsorbent material in the adsorption cylinder 203 evenly used, extending the service life of the adsorbent material and reducing the frequency and cost of replacing the adsorbent material.
[0039] In another embodiment, a vibrating filter 700 is provided below the adsorption mechanism 200, the vibrating filter 700 being used to separate the broken battery fragments and electrolyte.
[0040] The vibrating filter 700 is installed above the waste liquid collection tank 500 and extends into the waste collection tank 600. During the rotation of the first rotating seat 201 and the second rotating seat 202, the vibrating filter 700 will vibrate, thereby accelerating the separation process of battery fragments and electrolyte, and also making the battery fragments and electrolyte completely separated.
[0041] The vibrating filter 700 is in sliding contact with the waste liquid collection tank 500. Specifically, several sliding rods 701 are installed at the bottom of the vibrating filter 700. The sliding rods 701 are in sliding contact with the side wall of the waste liquid collection tank 500. An elastic element 702 is sleeved on the sliding rod 701. The elastic element 702 is set as a cylindrical spring. By setting the sliding rods 701, the stability of the movement of the vibrating filter 700 can be further ensured.
[0042] Both the first rotating seat 201 and the second rotating seat 202 are provided with a plurality of protrusions 210. The vibrating filter 700 is provided with a push rod 703 that rolls in contact with the protrusions 210. During the rotation of the first rotating seat 201 and the second rotating seat 202, the protrusions 210 will rotate. When the protrusions 210 come into contact with the push rod 703, they will push the push rod 703 downward, at which time the elastic element 702 is compressed. When the protrusions 210 disengage from the push rod 703, the vibrating filter 700 will reset under the elastic force of the elastic element 702. This process is repeated to achieve continuous vibration of the vibrating filter 700, thereby effectively promoting the separation of battery fragments and electrolyte. This not only improves the separation efficiency but also ensures the thoroughness of the separation, making subsequent electrolyte collection and battery fragment processing more convenient.
[0043] In addition, the vibrating filter 700 can effectively avoid clogging problems that may occur in traditional separation methods, thus improving the stability and reliability of the equipment.
[0044] It should be noted that the contact surface between the push rod 703 and the protrusion 210 is an arc-shaped surface, which can ensure a smoother contact between the protrusion 210 and the push rod 703 during rotation, reduce friction and wear, and at the same time ensure the stability of the vibrating filter 700 during movement and improve separation efficiency.
[0045] It should also be noted that the vibrating filter 700 is set at an angle, so that the broken battery fragments slide down into the waste collection box 600 under their own gravity and the action of the vibrating filter 700, thus avoiding the accumulation of battery fragments on the vibrating filter 700 and affecting the separation effect.
[0046] In addition, a sealing cover plate 800 is provided in this application. The sealing cover plate 800 is fixedly installed on the frame 400 to seal the crushing mechanism 100 and the adsorption mechanism 200, so as to prevent gas from leaking into the surrounding environment during the operation of the equipment and further ensure operational safety.
[0047] It should be noted that the sealing cover plate 800 is provided with a feeding pipe 801, which is fastened to the inlet 102 on the fixed cylinder 101 to feed the battery into the fixed cylinder 101 for crushing; a sealing cover plate is installed on the feeding pipe 801, and after the battery is fed into the fixed cylinder 101, the sealing cover plate is fastened to the feeding pipe 801 to further ensure the safety of the operating environment.
[0048] Working principle: Waste batteries are fed into the fixed cylinder 101 through the feed inlet 102, and then crushed by the spiral shredder 105. The crushed battery fragments and electrolyte are then discharged through the discharge outlet 103. During this process, the drive motor 300 synchronously drives the first rotating seat 201 and the second rotating seat 202 to rotate, thereby driving the adsorption cylinder 203 to rotate and adsorb the gases volatilized during the crushing process. The rotation of the first rotating seat 201 and the second rotating seat 202 simultaneously drives the vibrating filter 700 to reciprocate, thereby accelerating the separation of battery fragments and electrolyte, and allowing the battery fragments and electrolyte to enter the corresponding waste collection box 600 and waste liquid collection box 500, realizing the classified collection of battery fragments and electrolyte for convenient subsequent processing.
