[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0029] The core of this utility model is to provide an internal cleaning mechanism for a pulverizer used in carbon black processing, so as to improve the effective load capacity of the internal cleaning mechanism of the pulverizer used in carbon black processing.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1:

[0032] Please refer to Figures 1 to 7This utility model discloses an internal cleaning mechanism for a pulverizer used in carbon black processing, including a negative pressure dust collection mechanism 1 and a blower mechanism 2. The negative pressure dust collection mechanism 1 is connected to a dust collection pipe 4, and the end of the dust collection pipe 4 is connected to a foldable dust collection cover 5, which is used to extend into the feed inlet of the pulverizer for dust collection. The blower mechanism 2 is connected to a blower pipe 201, and the end of the blower pipe 201 is detachably connected to a blower head 202 suitable for different pulverizer structures. A first drive mechanism 203 is provided on the side wall of the blower pipe 201. The first drive mechanism 203 is a slow-speed rotation drive mechanism to avoid the first drive mechanism 203 rotating too fast, exceeding the rotational strength that the flexible rod 204 can withstand, causing the flexible rod 204 to break or deviate in rotation. The output end of the first drive mechanism 203 is connected to a flexible rod 204. The flexible rod 204 is a strip rod made of resin material or a flexible plastic rod. A brush 205 is provided on the flexible rod 204. The brush 205 is divided into multiple segments along the length of the flexible rod 204. The multi-segment design of the brush 205 makes it easy for the flexible rod 204 to bend without affecting each other or the bending of the flexible rod 204. Each segment of the brush 205 forms a cylindrical structure. The air pipe 201 extends from the discharge port of the crusher to blow and clean.

[0033] The working process and principle of the above structure are as follows:

[0034] In use, the suction pipe 4 and the foldable suction hood 5 are inserted into the feed inlet of the crusher. During insertion, the foldable suction hood 5 is retracted and folded. After entering the feed inlet, the foldable suction hood 5 is unfolded, with its opening facing downwards. Then, the blower pipe 201 and blower head 202 are inserted into the discharge outlet of the crusher, along with the flexible rod 204. Both the negative pressure suction mechanism 1 and the blower mechanism 2 are powered on. The blower mechanism 2 generates airflow, which is transmitted through the blower pipe 201 to the blower head 202. The blower head 202 blows the carbon black powder inside the crusher, especially the carbon black powder in various corners and crevices, making the carbon black... As the powder floats up, the first drive mechanism 203 drives the flexible rod 204 to rotate slowly. The brush 205 on the flexible rod 204 cleans the carbon black powder on the side wall of the pulverizer and the areas it can reach during the rotation. The carbon black powder floats around under the action of airflow, while the negative pressure dust collection mechanism 1 generates negative pressure suction force and sucks up the carbon black through the dust collection pipe 4 and the foldable dust collection cover 5, adsorbing all the carbon black powder floating in the pulverizer, thereby cleaning the carbon black powder inside the pulverizer. The cleaned carbon black powder can also be reused later. The combination of the blower mechanism 2 and the negative pressure dust collection mechanism 1 can be applied to different types of pulverizers, improving the applicability of the cleaning equipment.

[0035] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, the negative pressure vacuuming mechanism 1 is located above the blower mechanism 2, and a support base 3 is located below the blower mechanism 2. Several wheels 301 are located at the bottom of the support base 3. The negative pressure vacuuming mechanism 1 and the blower mechanism 2 are connected by a power cord, and a push-pull rod is connected to one side of the support base 3.

[0036] Most crushing equipment has its feed inlet located at the top and its discharge outlet at the bottom. Therefore, placing the negative pressure dust collection mechanism 1 above the blower mechanism 2 makes it easier for the dust collection pipe 4 to extend into the feed inlet and the blower pipe 201 to extend into the discharge outlet. The support base 3 and the traveling wheels 301 help to move the cleaning mechanism.

[0037] In another embodiment of this utility model, based on embodiment 1, as follows: Figures 1-2 as well as Figures 6-7 As shown, the foldable vacuum cleaner cover 5 includes a connector sleeve 501, which is detachably connected to the vacuum cleaner tube 4. Four hinge seats 5011, evenly spaced circumferentially around the axis of the connector sleeve 501, are provided on the outer surface of the other end of the connector sleeve 501. A support rod 502 is hinged to each hinge seat 5011. A hinge shaft 5021 is provided at the hinged end of the support rod 502 and the hinge seat 5011. A torsion spring 503 for driving the support rod 502 to unfold outwards is sleeved on the hinge shaft 5021. The four support rods 502 are covered by a flexible cover 504, which is connected to the support rods 502 by screws. The contact area between the flexible cover 504 and the support rods 502 is coated with adhesive. The flexible cover 504 is sealed to the outer surface of the connector sleeve 501 on the side closest to the connector sleeve 501. The flexible cover 504 and the connector sleeve 501 are connected by adhesive and further fixed and sealed by a sealing ring or locking clamp 7. The flexible cover 504 unfolds into a pyramidal structure. A pull rope 505 is fixedly connected to the free end of each support rod 502. A control hole 5012 is provided on the connector sleeve 501. The edges of the control hole 5012 are rounded to avoid the edges of the control hole 5012 from affecting the pull rope 505 and causing wear or tear on the pull rope 505. After the free end of the pull rope 505 passes through the control hole 5012, a pull ring 5051 is connected to it for pulling the support rod 502 to retract.

[0038] When the foldable vacuum hood 5 retracts, pulling the pull ring 5051 causes the pull cord 505 to retract. Under the tension of the pull cord 505, the free end of the support rod 502 rotates inward and compresses the torsion spring 503. The four support rods 502 move closer to each other, thereby causing the flexible cover 504 to retract, thus achieving the purpose of retracting the foldable vacuum hood 5. This makes it easy to insert or remove the foldable vacuum hood 5 from the feed inlet. When the foldable vacuum hood 5 needs to be unfolded, simply... When the pull ring 5051 is released, the four support rods 502 rotate outward and expand under the restoring elastic force of their respective torsion springs 503, thereby unfolding the flexible cover 504 and realizing the unfolding of the foldable vacuum hood 5. The overall structure is simple and easy to operate. A hook for limiting and fixing the pull ring 5051 can also be set on the connector sleeve 501. When the foldable vacuum hood 5 is retracted, several pull rings 5051 are fixed on the hook, which facilitates other operations by the staff.

[0039] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 6 and Figure 7 As shown, each support rod 502 has a limiting ring 5022 at one end near the connector sleeve 501. A grooved wheel 5013 is rotatably mounted inside the connector sleeve 501 corresponding to the position of each support rod 502. After each pull rope 505 passes through the limiting ring 5022 on its respective support rod 502, it passes around its corresponding grooved wheel 5013 and exits the connector sleeve 501 through the control hole 5012. The limiting ring 5022 mainly serves to limit the pull rope 505, preventing it from tangling. The grooved wheel 5013 helps reduce friction on the pull rope 505, preventing it from breaking during use. Furthermore, the reduced friction from the grooved wheel 5013 also makes it easier to pull.

[0040] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, the first drive mechanism 203 includes a drive motor and a reduction gearbox. The reduction gearbox is mainly used to adjust the speed ratio of the drive motor, reduce the output speed, and prevent it from exceeding the rotational limit of the flexible rod 204. The output end of the drive motor is connected to the input end of the reduction gearbox, and the flexible rod 204 is connected to the output end of the reduction gearbox. Both the drive motor and the reduction gearbox use small motor and reduction gear components.

[0041] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 5As shown, the negative pressure dust collection mechanism 1 includes a negative pressure dust collection box 101. A motor 102 is installed on the top of the negative pressure dust collection box 101. The output end of the motor 102 extends downward into the negative pressure dust collection box 101 and is connected to an impeller 103. A motor cover 104 is installed around the impeller 103. An exhaust port 105 is opened on the top of the negative pressure dust collection box 101 and communicates with the inside of the motor cover 104. A cartridge filter 106 is connected to the lower part of the motor cover 104. The cartridge filter 106 is a HEPA cartridge filter 106. A fine dust filter 107 is installed below the cartridge filter 106. The fine dust filter 107 is model XF9-16. A suction port 108 is installed on the lower side of the negative pressure dust collection box 101. A suction pipe 4 is connected to the suction port 108. A dust collection box 109 is installed at the bottom inside the negative pressure dust collection box 101.

[0042] The motor 102 drives the impeller 103 to rotate, generating negative pressure suction. A negative pressure space is formed inside the negative pressure dust collection box 101, thereby generating suction force to draw carbon black powder into the negative pressure dust collection box 101. After the carbon black powder enters the negative pressure dust collection box 101 through the dust inlet 108, the air passes through the fine dust filter 107 and the cartridge filter 106 in sequence. The carbon black powder finally falls into the dust collection box 109 for later use. After the airflow is filtered, it is discharged from the exhaust port 105.

[0043] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, both the blower pipe 201 and the suction pipe 4 are corrugated pipes. The blower pipe 201 and the suction pipe 4 have the same structure and model. The free ends of both the blower pipe 201 and the suction pipe 4 are provided with connecting joints 6 with external threads, which are used to connect the blower head 202 or the foldable vacuum cover 5.

[0044] With this configuration, the blower hose 201 and the vacuum hose 4 can be interchanged, increasing the product's compatibility and making it easier to replace and maintain the vacuum hose 4 and the blower hose 201.

[0045] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 3 As shown, the blower head 202 includes a first threaded connector 2021 and a blower bend 2022. The blower bend 2022 and the first threaded connector 2022 are integrally formed. The first threaded connector 2021 is connected to the connecting connector 6 by threads.

[0046] The 2022 setting of the blower bend helps to blow air into some corners and crevices.

[0047] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 4As shown, the blower head 202 includes a second threaded connector 2023 and a blower straight pipe 2024. The blower straight pipe 2024 has blower holes 2025 spaced at equal intervals. The blower straight pipe 2024 and the second threaded connector 2023 are integrally formed. The second threaded connector 2023 is connected to the connecting connector 6 by threads.

[0048] The 2024 air blower tube helps to blow away the carbon black powder adsorbed on the inner side of the pulverizer.

[0049] In another embodiment of this utility model, based on embodiment 1, as follows: Figure 1 As shown, clamps 7 for fixing the vacuum tube 4 and the blower mechanism 201 are respectively provided on the outer walls of the negative pressure vacuum box 101 and the blower mechanism 2.

[0050] The clamp 7 is mainly used to fix the vacuum hose 4 and the blower hose 201 when they are not in use, by snapping them into the clamp 7.
