Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery production technology, and in particular to an automatic cleaning device and a hopper. Background Technology
[0002] Graphite anode materials are widely used as negative electrode materials in lithium-ion batteries. Before graphite raw materials can be used as anode materials, they must first be pulverized. The pulverized graphite powder is then transported to a silo for storage via an elevator, and then fed into the production line when needed. During the discharge process from the silo, the graphite powder easily adheres to the silo's inner wall due to static electricity, moisture, and the less-than-smooth inner wall of the silo, affecting the discharge speed and even clogging the silo outlet. Currently, silo cleaning is done by directly feeding powder into the silo for cleaning, which is not only cumbersome and inefficient but also costly.
[0003] Therefore, there is an urgent need for an automatic cleaning device and silo to solve the above problems. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] like Figure 1As shown, this embodiment provides an automatic cleaning device that can be installed on a hopper body 100 to clean residual powder within the hopper body 100. The automatic cleaning device includes an air source assembly, a purging assembly, and a vibration assembly. The air source assembly includes a pulse valve 1 and a main gas pipeline. One end of the main gas pipeline is connected to an external air source to introduce gas into the main gas pipeline. The pulse valve 1 is located on the main gas pipeline. The purging assembly includes a first gas pipeline and jet nozzles 2. One end of the first gas pipeline is connected to the main gas pipeline and is located downstream of the pulse valve 1. The other end of the first gas pipeline is connected to the jet nozzles 2. Multiple jet nozzles 2 are provided, all of which are located within the hopper body 100 and face the center of the hopper body 100. The pulse valve 1 opens or closes according to the set pulse time, controlling the main gas pipeline to supply pulsed gas to the jet head 2. The pulsed gas has a short release time and adjustable frequency, providing high-energy gas impact in a short time. The jet heads 2 are all oriented towards the center of the hopper body 100, and the ejected pulsed gas directly impacts the powder adhering to the side wall of the hopper body 100, causing the adhering powder to fall off. The vibration assembly includes an air hammer 3 and a second gas pipeline. One end of the second gas pipeline is connected to the main gas pipeline and is located downstream of the pulse valve. The other end of the second gas pipeline is connected to the air inlet of the air hammer 3. The pulse valve 1 opens or closes according to the set pulse time, controlling the main gas pipeline to supply pulsed gas to the air hammer 3, thereby starting the air hammer 3. The air hammer 3 is located outside the hopper body 100 and can hammer the side wall of the hopper body 100, causing the powder adhering to the side wall of the hopper body 100 to fall off. The automatic cleaning device provided in this embodiment is equipped with a blowing component and a vibration component to clean the powder adhering to the side wall of the hopper body 100, which can effectively improve cleaning efficiency and reduce labor costs.
[0034] In this embodiment, multiple sets of jet heads 2 are arranged at intervals along the height direction of the hopper body 100, with each set containing multiple jet heads 2. These multiple jet heads 2 are also arranged at intervals along the circumference of the hopper body 100. Each jet head 2 has a small hole, which allows the pulsed gas flowing through the first gas pipeline to be dispersed into multiple directions. The multiple jet heads 2 spaced at intervals along the circumference of the hopper body 100 ensure that the emitted pulsed gas covers the circumference of the hopper body 100, while the multiple sets spaced at intervals along the height direction ensure that the emitted pulsed gas covers different positions along the height direction of the hopper body 100. This ensures the purging range of the pulsed gas on the sidewalls of the hopper body 100 and guarantees the purging efficiency of the powder.
[0035] Optionally, the first port of the first gas pipeline is detachably connected to the jet head 2. The first port is embedded in the side wall of the silo body 100 and faces the center of the silo body 100. In specific implementation, the first gas pipeline can be embedded in the side wall of the silo body 100, and an installation hole is provided on the side wall of the silo body 100. The first port of the first gas pipeline passes through and is fixed to the installation hole. The installation hole can be a threaded hole, and the outer wall of the jet head 2 is provided with a matching thread. The jet head 2 can be fixed to the first port, that is, fixed to the side wall of the silo body 100, through a threaded connection. Since the silo body 100 is used to contain powder, if the small hole on the jet head 2 is blocked by powder or other impurities during long-term use of the silo body 100, and the pulse gas cannot clean the blockage, the jet head 2 can be removed for manual cleaning.
[0036] Furthermore, the automatic cleaning device also includes a collection component, which comprises a collection bag 4 and a negative pressure pump. The collection bag 4 is connected to the dust removal port of the hopper body 100, and the negative pressure pump is mounted on the collection bag 4. The negative pressure pump is used to draw in the gas inside the collection bag 4. Because the collection bag 4 is connected to the inner cavity of the hopper body 100, when the negative pressure pump is working, it can draw in the gas between the collection bag 4 and the inner cavity, thereby removing the powder inside the hopper body 100 and achieving the collection of the aforementioned cleaned powder.
[0037] Optionally, the collection assembly also includes a connecting pipe 5, one end of which is connected to the dust collection port, and the other end of which is detachably connected to the inlet of the collection bag 4. After one collection is completed, the connection between the collection bag 4 and the connecting pipe 5 can be disconnected, and the collection bag 4 can be removed to process the collected powder, ensuring that the subsequent automatic cleaning device can operate normally.
[0038] In practice, during the discharge process, an external air source can be turned on and the second gas pipeline can be opened so that the air hammer 3 can hammer the side wall of the hopper body 100 to accelerate the discharge and reduce the powder adhering to the side wall of the hopper body 100. After the discharge is completed, the second gas pipeline can be turned off and the first gas pipeline can be turned on so that the pulse gas can impact the side wall of the hopper body 100, thereby causing the adhering powder to fall off. Finally, the collection component can be turned on to collect the fallen powder. After the collection is completed, the collection bag 4 can be removed to process the collected powder.
[0039] Optionally, multiple air hammers 3 are provided, and the multiple air hammers 3 are arranged at intervals along the circumference of the hopper body 100 to increase the discharge speed and reduce the powder adhering to the side wall of the hopper body 100.
[0040] This embodiment also provides a hopper, including a hopper body 100 and the aforementioned automatic cleaning device. The automatic cleaning device is disposed on the hopper body 100 and is equipped with a blowing component and a vibration component to clean the powder adhering to the side wall of the hopper body 100, which can effectively improve cleaning efficiency and reduce labor costs.
[0041] Optionally, the silo body 100 has an inlet 1001, an outlet 1002, and a mounting hole. The inlet 1001 is located at the top of the silo body 100, the outlet 1002 is located at the bottom of the silo body 100, and the mounting hole is located on the side wall of the silo body 100. Powder can enter the silo body 100 through the inlet 1001 and exit the silo body 100 through the outlet 1002. The first port of the first gas pipeline connected to the jet nozzle 2 is located at the mounting hole. In specific implementations, the silo body 100 is generally a conical structure, and the top dimension of the conical structure is much larger than the bottom dimension of the conical structure. This allows the powder to flow more smoothly to the outlet 1002 under the action of gravity, reducing accumulation and blockage in the silo. The discharge port 1002 is equipped with a discharge cover. During the discharge process, the discharge cover is opened so that the powder can leave the hopper body 100 through the discharge port 1002. After the discharge is completed, the discharge cover is closed. The powder adhering to the side wall of the hopper body 100 can be collected by the blowing component and the collecting component to achieve automatic cleaning of the hopper body 100.
[0042] Optionally, the hopper body 100 also has a dust removal port, which is located on the side wall of the hopper body 100 and near the discharge port 1002. The dust removal port is connected to the collection component of the automatic cleaning device. The dust removal port is close to the bottom of the hopper body 100 so that powder that has detached from the bottom of the hopper body 100 can be quickly sucked into the collection bag 4.
[0043] Optionally, the hopper also includes a stirring paddle 200, which is rotatably disposed within the hopper body 100. The stirring paddle 200 can prevent powder from clumping, improve the flowability of the powder, and accelerate discharge.
[0044] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
