Description

Technical Field

[0001] This utility model relates to a noise reduction and dust removal device for a tapped density meter. Background Technology

[0002] Lithium-ion batteries mainly consist of a positive electrode, a negative electrode, an electrolyte, and a separator. The choice of negative electrode material directly affects the battery's energy density. During the production of negative electrode materials, tap density is a crucial performance parameter that influences the battery's energy density and cycle performance. Higher tap density increases the lithium storage capacity of the negative electrode material, thereby improving the battery's energy density. Simultaneously, higher tap density also enhances the mechanical strength of the negative electrode material, reducing capacity loss due to material shedding. Therefore, the research and control of tap density is a vital aspect of the development and manufacturing process of battery negative electrode materials.

[0003] Currently, in the production process of lithium battery materials, tap density is mostly measured using a vibration device. The main principle is to place a certain amount of powder in a container and vibrate it until the powder volume no longer decreases. The mass of the powder divided by the volume after vibration gives the tap density of the material. During the test, the up-and-down vibration of the vibration assembly, which can last for more than ten minutes, generates significant environmental noise. This is especially true when several tap density meters are used simultaneously, severely impacting the work of personnel. Therefore, effective noise reduction measures for tap density meters are essential. Furthermore, due to continuous vibration, dust leakage is inevitable, causing dust pollution and affecting the experimental environment. Therefore, effective dust prevention measures for tap density meters are also necessary.

[0004] Although existing tapped density meters have added noise reduction and dust removal devices (e.g., a protective cover with noise reduction material is added to the top of the tapped density meter), they have certain limitations: First, the protective cover needs to be removed or covered before and after the test, which may cause it to slip and fall, breaking the glass container and affecting the test progress; second, the installed glass measuring cylinder is easy to break during placement; third, the installation and disassembly operations are inconvenient, and the protective cover needs to be removed after the test, and the dust in the equipment needs to be cleaned manually. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as the susceptibility of noise reduction devices to damage during operation, inconvenience in disassembly and assembly, and insufficient noise reduction effect, a noise reduction and dust removal device for a tapped density meter is provided. This device incorporates multiple noise reduction measures, including sound-absorbing sponge and acrylic panels, and works in conjunction with a dust collection device to effectively reduce the noise generated during the operation of the tapped density meter. Furthermore, this noise reduction and dust removal device is easy to disassemble and assemble, preventing damage to the equipment within.

[0006] This utility model provides a noise reduction and dust removal device for a tapped density meter, which includes a box for placing the tapped density meter; the inner wall of the box is lined with sound-absorbing sponge, and the side of the sound-absorbing sponge away from the inner wall of the box is also provided with an acrylic plate; a base is fixed above the tapped density meter, and the base is used to place a container for holding the sample; a through opening is provided on one side wall of the box, and the opening is connected to the dust removal device through a connecting pipe.

[0007] In this invention, the purpose of "providing an acrylic plate on the side of the sound-absorbing sponge away from the inner wall" is as follows: First, by combining the acrylic plate with the sound-absorbing sponge, the sound absorption and noise reduction effects are further improved; second, it can reduce the adhesion and accumulation of dust generated during vibration on the sound-absorbing sponge. When the sound-absorbing sponge is used alone, the sound absorption effect is greatly reduced after dust adheres to it.

[0008] In this invention, a housing is used to reduce noise in the vibration compaction device, making operation more convenient and safer.

[0009] In this invention, the sound-absorbing sponge can be made of polyester fiber or melamine foam. Utilizing its porous structure and material properties, it achieves sound absorption by absorbing and converting sound wave energy, which can effectively reduce noise and improve the laboratory environment.

[0010] In this invention, the dust removal device prevents dust from accumulating in certain areas and generating greater noise.

[0011] In this invention, the container for holding the sample is generally a graduated cylinder.

[0012] In this invention, the connecting pipe can be a PVC flexible hose.

[0013] In this invention, the dust collection device can be an upright vacuum cleaner, used to remove and collect the dust deposited inside the box, eliminating the need for manual dust removal.

[0014] In this invention, the opening can be circular.

[0015] In some embodiments, the interior of the housing is provided with a plurality of limiting members, which are used to fix the acrylic plate and to limit the distance between the acrylic plate and the sound-absorbing sponge.

[0016] In a specific embodiment, the limiting member includes a rectangular groove, and every two rectangular grooves are disposed on the inner wall surface of the box body in a direction parallel to the sound-absorbing sponge.

[0017] In a preferred embodiment, the distance between the two sides of the rectangular groove may be slightly greater than the width of the acrylic sheet.

[0018] The distance between the two sides of the rectangular groove and the acrylic sheet can be 1 mm; if the distance is too large, the acrylic sheet is prone to shaking during testing; if the distance is too small, the acrylic sheet is difficult to install and remove.

[0019] In this invention, the distance between the acrylic plate and the sound-absorbing sponge is equal to the thickness of one side of the rectangular groove.

[0020] In a preferred embodiment, one edge of the rectangular groove is attached to the sound-absorbing sponge, thereby ensuring that the acrylic plate inserted in the rectangular groove covers the surface of the sound-absorbing sponge as much as possible.

[0021] In this utility model, the enclosure can be referred to as a noise-proof cabinet.

[0022] In some embodiments, the enclosure is made of acrylic material; in addition to its soundproofing effect, the material also has a sound-absorbing effect; furthermore, using this transparent material allows for observation of any abnormalities during the operation of the tapped density meter, avoiding the use of tempered material which would make the interior of the enclosure invisible, and tempered material is prone to breaking glass instruments such as measuring cylinders.

[0023] In some embodiments, the tapped density meter is equipped with a control panel for controlling the operating status and process parameters of the tapped density meter.

[0024] In a specific implementation, a switch door is provided on the wall of the box located on one side of the control panel; the switch door facilitates the placement of the tapped density meter and the installation, disassembly and cleaning of the sample measuring cylinder before and after testing.

[0025] The number of doors to be opened and closed can be two.

[0026] The switch door can be referred to as a noise-proof cabinet door, and its material can be acrylic, which has excellent sound insulation performance and effectively reduces noise pollution.

[0027] In some embodiments, a sliding door is provided on the top surface of the enclosure.

[0028] In some embodiments, the number of sound-absorbing sponges is two, and the two sound-absorbing sponges are symmetrically arranged on the inner wall surfaces of the box on both sides of the tapped density meter, that is, the two sound-absorbing sponges fill the left and right sides of the box.

[0029] In some embodiments, the opening is positioned at a height lower than the base to facilitate the collection of dust deposited at the bottom of the housing using the dust collection device.

[0030] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0031] The reagents and raw materials used in this invention are all commercially available.

[0032] The positive and progressive effects of this utility model are as follows:
