Description

Technical Field

[0001] The present application relates to the technical field of activated carbon manufacturing, and in particular to a carbonaceous material grinding and supply system for activated carbon production. Background Art

[0002] After activated carbon production is complete, the product needs to be shaped into the desired form before packaging. Some activated carbon blocks require grinding into a powdered form before packaging. Therefore, the resulting activated carbon blocks need to be transferred to a grinding mill to form a powder, which is then transferred to packaging equipment. Some powders, after being ground by the grinding mill, need to be pressed into a predetermined shape, depending on the environment in which the activated carbon is used; some are pressed into a ring shape. Consequently, multiple transfers are required between the relevant equipment. Existing transfer methods typically use suction equipment to transfer powdered material from one location to another. This suction method requires high power and can easily cause carbon powder to leak, affecting the workshop environment and the health of workshop personnel. Furthermore, during transfer, carbon powder easily absorbs moisture from the environment, reducing its dryness. Furthermore, due to static electricity generated by moisture and friction, carbon powder easily sticks to the inner walls of the transfer equipment during transfer. This stuck carbon powder not only affects the heat dissipation of the transfer equipment but also increases the output power of the drive equipment. Therefore, optimization of the transfer mechanism in the production system of activated carbon or related products is urgently needed to address the aforementioned technical issues.

[0021] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0022] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity from another, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that an article or terminal device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such article or terminal device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the article or terminal device comprising the element.

[0023] After activated carbon production is complete, the product needs to be processed into the target form before packaging. Some activated carbon blocks need to be ground into powder before packaging. Therefore, the generated activated carbon blocks need to be transferred to a grinding mill 2 to be ground into powder, and then transferred to the packaging equipment. Some of the powders after grinding in the grinding mill 2 need to be pressed into a preset shape. This shape is related to the use environment of the activated carbon, and some are pressed into a ring shape. Therefore, multiple transfers are required between the relevant equipment. The existing transfer method generally uses a suction device to transfer the powder material from one location to another. This suction method requires a large amount of power and can easily cause carbon powder to leak, affecting the workshop environment and the health of workshop personnel. In addition, the carbon powder easily absorbs moisture from the environment during the transfer process, reducing its dryness. Moreover, due to static electricity generated by moisture and friction, the carbon powder easily sticks to the inner wall of the transfer equipment during the transfer process. The sticking carbon powder not only affects the heat dissipation of the transfer equipment, but also increases the output power of the driving equipment. Therefore, the present invention urgently needs to optimize the transfer mechanism in the production system of activated carbon or related products to solve the aforementioned technical problems, as described below.

[0024] The utility model provides a grinding and supplying system for carbon-containing materials in the production of activated carbon, comprising a feed transmission mechanism 1, a grinding mill 2, and a discharge transmission mechanism 3, wherein the feed port of the grinding mill 2 is connected to one end of the feed transmission mechanism 1, and the discharge port of the grinding mill 2 is connected to one end of the discharge transmission mechanism 3; wherein the feed transmission mechanism 1 comprises: a transmission trough 11, a transmission belt 12 installed in a gap with the inner wall of the transmission trough 11, a cover plate sealedly connected to the trough opening of the transmission trough 11, and a heating component arranged on the outer wall of the transmission trough 11 and the outer surface of the cover plate, and the heating element of the heating component is insulated from the outer surface of the cover plate and the outer wall of the transmission trough 11; in addition, the discharge transmission mechanism 3 comprises: a U-shaped trough, a spiral guide plate 31 arranged in the U-shaped trough, the guide plate 31, one end of the guide plate 31 is connected to a driving device, one end of the guide plate 31 is electrically connected to the brush of the conductive mechanism, and the grinding mill 2 cabin of the grinding mill 2 is grounded after being connected to the conductive mechanism.

[0025] like Figure 1 As shown (to show the position of the conveyor belt in the conveyor slot, the conveyor belt is placed in the Figure 1 (Indicated by a dotted box in the figure), the present invention provides a system for grinding and supplying carbon-containing materials for producing activated carbon. The system includes a feed conveying mechanism 1, a grinding mill 2, and a discharge conveying mechanism 3. The feed port of the grinding mill 2 is connected to one end of the conveying mechanism, and the discharge port of the grinding mill 2 is connected to one end of the discharge conveying mechanism 3. That is, the large activated carbon blocks coming out of the carbonization furnace pass through the feed conveying mechanism 1 and enter the grinding mill 2. The grinding mill 2 grinds the large activated carbon blocks into particles or powdered activated carbon of a preset diameter, which are then transported to the packaging station by the discharge conveying mechanism 3 for packaging. Among them, the feed conveying mechanism 1 is a closed transmission route composed of a transmission trough 11 and a cover plate. A heating component is provided on the outer surface of the conveying mechanism to keep the interior of the conveying mechanism in a dry state, thereby preventing the hot activated carbon coming out of the carbonization furnace from absorbing moisture in the air in the conveying mechanism and causing it to become damp. Furthermore, the discharge conveyor mechanism 3 comprises a U-shaped trough and a spiral guide plate 31. The guide plate 31 is electrically connected to the brushes of the conductive mechanism to remove static electricity generated by friction during the conveyance of the activated carbon, thereby preventing static electricity from adsorbing the activated carbon powder to the surface of the conveyor mechanism. The structure of the present utility model solves the problem of carbon powder adhering to the wall due to moisture or static electricity in existing conveyor or feeding systems, thereby improving the practicality of the activated carbon delivery system.

[0026] The heater can be used as follows: Figure 2 The PCT heater shown has a heating unit made of ceramic sheets, which has a constant temperature effect, automatic over-temperature protection, and a long service life. The outermost side of the heater is wrapped with insulating ceramic, which has good insulation performance and prevents general heaters from leaking electricity and endangering the safety of operators.

[0027] In addition, the guide plate 31 is a composite structure of a double-layer PVC plastic (i.e., polyvinyl chloride plastic) plate sandwiched with a metal plate. The metal plate is electrically connected to the brush. The metal plate is exposed at the edge and surface of the PVC plastic plate, and the edge of the PVC plastic plate is provided with rounded corners.

[0028] The PVC sheet's hardness and smooth surface reduce friction with the powdered activated carbon, minimizing the chance of triboelectric charging. At the very edge of guide plate 31, the metal plate protrudes from the PVC sheet, allowing the brushes of the conductive mechanism above to easily contact it. Additionally, at other curved locations on guide plate 31, the metal plate is embedded in the PVC sheet to discharge static electricity from the powder in contact onto the conductive plate and ultimately to the ground.

[0029] In some embodiments, the system further includes an electromagnetic relay electrically connected to the brushes. When the electromagnetic relay is powered, the main switch of the grinding powder supply system is disconnected. When the amount of static electricity collected in the conductive mechanism reaches a certain level, or when the conductive mechanism has not fully discharged the static electricity, the electromagnetic relay is connected, disconnecting the main switch of the grinding powder supply system, halting transmission and protecting the personal safety of operators in the working environment.

[0030] like Figure 3 As shown ( Figure 3 The arrow on the middle conveyor belt indicates the moving direction of the conveyor belt), the feed conveyor mechanism 1 also includes a circulation mechanism for the conveyor belt 12, which includes: a driving wheel, a pair of curling wheels 5, a pair of pressing wheels 6, and a driven wheel. The driving device is connected to the driving wheel, the pair of curling wheels 5 contacts the bottom surface of the conveyor belt 12 and approaches each other to roll up the two sides of the conveyor belt 12, and the pair of pressing wheels 6 contacts the front surface of the conveyor belt 12 and moves away from each other to flatten the two sides of the conveyor belt 12; the driven wheel and the driving wheel are both sleeved with the conveyor belt 12. Figure 3 The arrows next to the middle curling wheel 5 and the pressing wheel 6 indicate the directions of their forces acting on the conveyor belt 12 .

[0031] The aforementioned conveyor belt 12 can be a hard conveyor belt 12 with relatively stable thermoplastic properties, such as PVC plastic.

[0032] In other embodiments, the inner wall of the U-shaped trough includes a polishing layer, which further reduces the friction coefficient between the powder and the inner wall of the U-shaped trough, thereby reducing the generation of frictional static electricity. Furthermore, the device includes thermal insulation and a light shield. The thermal insulation is bonded to the outer surfaces of the feed conveyor 1 and the discharge conveyor 3 to prevent the loss of heat generated by the heating assembly. The light shield is located within the space where the feed conveyor 1, grinding mill 2, and discharge conveyor 3 are located.

[0033] In addition, it can also include a hopper, the bottom of the hopper is connected to the U-shaped trough, and the hopper mouth is connected to the discharge end of the grinding mill 2; the discharge end of the grinding mill 2 is provided with a dust bag, and the other end of the dust bag is connected to the hopper mouth; the transmission trough 11 of the feed transmission mechanism 1 also includes a dust suction device.

[0034] The hopper is used to buffer a portion of the material and facilitate its delivery to the target location. Dust bags and dust collection devices are used to absorb localized dust leaks from the supply system, reducing carbon dust in the workspace and protecting personnel.

[0035] Finally, the utility model provides an activated carbon production carbon-containing material grinding and supply system, which includes a feed transmission mechanism 1, a grinding mill 2, and a discharge transmission mechanism 3. The feed port of the grinding mill 2 is connected to one end of the feed transmission mechanism 1, and the discharge port of the grinding mill 2 is connected to one end of the discharge transmission mechanism 3; wherein, the feed transmission mechanism 1 includes: a transmission trough 11, a transmission belt 12 installed in the gap with the inner wall of the transmission trough 11, a cover plate sealedly connected to the trough opening of the transmission trough 11, and a heating component arranged on the outer wall of the transmission trough 11 and the outer surface of the cover plate, and the heating element of the heating component is insulated from the outer surface of the cover plate and the outer wall of the transmission trough 11; in addition, the discharge transmission mechanism 3 includes: a U-shaped material trough, a spiral guide plate 31 arranged in the U-shaped material trough, the guide plate 31, one end of the guide plate 31 is connected to the driving device, one end of the guide plate 31 is electrically connected to the brush of the conductive mechanism, and the grinding mill 2 cabin of the grinding mill 2 is grounded after being connected to the conductive mechanism. The utility model improves the practicability of the activated carbon supply system.
