Description

Technical Field

[0001] This utility model relates to the field of cement packaging equipment, specifically to a pneumatic dust removal device for a cement cleaning machine. Background Technology

[0002] Cleaning cement bags is an indispensable and crucial step in the entire cement production process. Freshly produced cement bags often have a large amount of cement dust adhering to their surface. If this dust is not cleaned promptly, it will continue to disperse during handling and storage, polluting the air in the production workshop, causing dust concentrations to exceed standards and harming the respiratory health of operators, as well as creating continuous dust pollution in the surrounding environment. More importantly, the dust on the cement bags can severely affect the normal operation of the bag-grabbing equipment. Dust easily accumulates on key components such as the robotic arms, conveyor belts, and sensors of the bag-grabbing equipment, causing mechanical jamming and transmission problems.

[0003] Existing dust removal devices typically employ a single airflow structure, which makes it difficult to thoroughly clean the surface of cement bags, resulting in poor cleaning performance. Furthermore, some dust removal devices lack effective dust recovery systems, easily causing dust to fly around, polluting the working environment and affecting the health of operators.

[0004] Therefore, there is a need for a high-efficiency and environmentally friendly pneumatic dust removal device for bag cleaning machines. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] First embodiment: See Figures 1-2 As shown, this utility model provides a pneumatic dust removal device for a cement bag cleaning machine, including a dust blowing component, an air source 2, and a dust removal component. The dust blowing component, as a dust removal structure that directly acts on the cement bag, includes multiple air blowing pipes 1. The air blowing pipes 1 are distributed in different positions in the cement bag dust removal operation area according to the shape of the cement bag and the dust removal requirements, and can blow dust off the cement bag from multiple angles. Each air blowing pipe 1 is provided with multiple air blowing ports 101. These air blowing ports 101 are arranged at a certain interval to ensure that the blown airflow can evenly cover the surface of the cement bag. The air inlet end of the air blowing pipe 1 is connected to the air outlet end of the air source 2. The compressed air provided by the air source 2 is delivered to each air blowing port 101 through the air blowing pipe 1, and finally forms a high-speed airflow that blows onto the cement bag, blowing off the dust attached to the surface of the cement bag.

[0020] The dust removal assembly is responsible for collecting and processing the blown-off dust, including a dust collection hood 4, a storage chamber 3, and a filter box 302. The dust collection hood 4 is located outside the cement bag dust removal operation area and can limit the dust-laden air generated during the dust removal process to a certain range to prevent dust from spreading to the surrounding environment. The outer end of the dust collection hood 4 is connected to the storage chamber 3 through a pipe. Under the influence of airflow, the blown-off dust enters the storage chamber 3 along with the air.

[0021] The storage chamber 3 is equipped with a cleaning door 301. When the dust collected in the storage chamber 3 reaches a certain amount, the operator can open the cleaning door 301 to clean the dust. The storage chamber 3 is also equipped with a filter box 302. The dusty air entering the storage chamber 3 will first pass through the filter box 302 for filtration. The dust in the air is trapped by the filter material in the filter box 302, and the purified air is discharged from the air outlet of the filter box 302. The air outlet of the filter box 302 is connected to the air inlet of the air source 2, so that the purified air can be reused by the air source 2 to form a circulating airflow system, which saves energy and further reduces environmental pollution.

[0022] Air source 2 is equipped with an air inlet pipe 201. When air source 2 needs to be replenished, external air enters the air source 2 through the air inlet pipe 201. After being compressed by air source 2, it is converted into compressed air with a certain pressure, and then delivered to the blowing pipe 1 through the outlet to provide power for the soot blowing operation. The setting of the air inlet pipe 201 enables air source 2 to independently obtain external air, unaffected by the airflow circulation in the soot cleaning components, ensuring sufficient and stable air supply from air source 2, thereby ensuring the continuous and efficient operation of the entire soot cleaning device.

[0023] The first embodiment differs from the first embodiment in that: The air blowing duct 1 adopts a zigzag design. This structure can better adapt to the shape of the cement bag, allowing the air outlet 101 to blow air from an angle that is closer to the surface of the cement bag. Compared with a straight duct, the zigzag air blowing duct 1 can reduce dead angles in the airflow process, allowing all parts of the cement bag to be impacted by a uniform airflow, thus improving the thoroughness of dust removal.

[0024] Multiple air outlets 101 are provided along the length of the air blowing duct 1. The number of these air outlets 101 is not fixed, but is adapted to the length of the air blowing duct 1. For example, a shorter air blowing duct 1 may have 3-5 air outlets 101, while a longer air blowing duct 1 will have a correspondingly increased number of air outlets 101, generally 6-10, to ensure that there are enough air outlets 101 along each section of the duct to clean the cement bag. At the same time, all air outlets 101 are evenly distributed along the length of the duct, and the spacing between two adjacent air outlets 101 is consistent. This ensures that the airflow blown from each air outlet 101 forms a uniform coverage on the surface of the cement bag, avoiding incomplete cleaning in some areas.

[0025] It also includes a support cover 102 located on the outside of all the air blowing pipes 1. The support cover 102 mainly serves to fix and protect the air blowing pipes 1. It can stably position the multiple zigzag air blowing pipes 1 in the preset dust removal position, prevent the air blowing pipes 1 from shifting or shaking during airflow impact or equipment operation, and ensure that the air blowing nozzle 101 is always aligned with the area of ​​the cement bag that needs to be cleaned.

[0026] The support cover 102 has through holes corresponding to the air outlets 101. The position of each through hole is precisely aligned with the corresponding air outlet 101, and the diameter of the through hole is slightly larger than the diameter of the air outlet 101. This design does not obstruct the airflow from the air outlet 101, and the structure of the support cover 102 can guide the airflow around the air outlet 101, making the airflow more concentrated and blowing it onto the cement bag, thus enhancing the dust removal effect. At the same time, it can also prevent external debris from contacting the air outlet 101, reducing the possibility of the air outlet 101 becoming clogged.

[0027] The third embodiment differs from the first embodiment in that: The support cover 102 is connected to the cylinder body of the electric telescopic cylinder 5 via a connecting rod 501. The support cover 102 provides stable support for the blowing duct 1. The connecting rod 501 is located near the top of the support cover 102. The telescopic end of the electric telescopic cylinder 5 extends downward and is fixedly connected to the top of the air collecting hood 4. In actual operation, when the number or stacking height of cement bags changes, the electric telescopic cylinder 5 adjusts the height of the air collecting hood 4 by telescoping. If there are many cement bags and the stacking height is high, the electric telescopic cylinder 5 shortens, causing the air collecting hood 4 to move upward and maintain a suitable distance from the top of the cement bags. If there are few cement bags and the stacking height is low, the electric telescopic cylinder 5 extends, pushing the air collecting hood 4 downward and bringing it closer to the surface of the cement bags. Through this adjustment, the air collecting hood 4 can always be close to the cement bag cleaning area, enhancing the concentration of negative pressure suction, improving the adsorption effect of blown-off dust, and reducing dust overflow.

[0028] In a preferred embodiment, a distance sensor is installed inside the gas collection hood 4. This sensor is installed at a suitable position on the inner side wall of the gas collection hood 4 and can accurately detect the distance between the gas collection hood 4 and the cement bag, obtain the height and position information of the cement bag in real time, and transmit this information to the control module in the form of an electrical signal. An electrically controlled valve is installed on the air guide pipe 201 and an electrically controlled valve is installed at the air inlet end of the air blowing pipe 1. Referring to the attached drawings, since there are multiple air blowing pipes 1 and they are distributed vertically, the air blowing pipes 1 at different heights correspond to the cleaning areas at different heights of the cement bag. In this case, the control module can use the cement bag height information detected by the distance sensor to accurately control the opening state of the electrically controlled valve at the air inlet end of the air blowing pipe 1 corresponding to the height of the cement bag. This can not only ensure the cleaning effect, but also reasonably distribute the airflow, further improve the energy utilization rate, and make the entire cleaning process more efficient and accurate.

[0029] The electric telescopic cylinder 5, distance sensor, electric control valve on the air blowing duct 1, and electric control valve on the air guiding duct 201 are all electrically connected to the control module for automatic control of the soot blowing and cleaning process. Through the coordinated work of each component and the control module, automated control is achieved, which not only improves the cleaning efficiency, but also allows for precise adjustment according to the actual situation of the cement bag, ensuring a stable and reliable cleaning effect.

[0030] The fourth embodiment differs from the first embodiment in that: If the air blowing duct 1 is a flexible duct, then the air blowing duct 1 has good flexibility and bendability, which allows it to flexibly adjust its shape according to changes in the external structure, providing a basic condition for subsequent folding operations; the support cover 102 includes two rotatably connected boxes, which can be rotated by connecting parts such as hinges. The boxes are provided with through holes corresponding to the air blowing port 101, and the connecting rod 501 is inserted into the support cover 102.

[0031] The connecting rod 501 and the support cover 102 are connected by an insertion joint. When the support cover 102 needs to be folded, the connecting rod 501 can be pulled out of the support cover 102 to disconnect the connection. Then, by rotating the two housings, the support cover 102 can be folded up. Since the air blowing duct 1 is a flexible duct, it can bend and fold synchronously with the shape change of the support cover 102 during the folding process.

[0032] The storage chamber 3 has an opening, and a cleaning door 301 is detachably connected to the opening to seal it. A sealing gasket is provided on the contact surface between the cleaning door 301 and the opening. As the core component for collecting dust, the storage chamber 3 has an opening on its side wall. The size of the opening is designed according to the daily dust cleaning needs to facilitate the operator to clean the inside of the storage chamber 3.

[0033] A cleaning door 301 is detachably connected to the opening. This detachable connection is typically secured with bolts; both the edge of the cleaning door 301 and the edge of the opening of the storage compartment 3 have corresponding screw holes, and the two are tightly connected together by bolts. When dust accumulates to a certain amount inside the storage compartment 3, the operator can unscrew the bolts, remove the cleaning door 301 from the opening, thoroughly clean the dust inside the storage compartment 3, and then reinstall the cleaning door 301 back into the opening and tighten the bolts. A sealing gasket is provided on the contact surface between the cleaning door 301 and the opening. When the cleaning door 301 is closed, the sealing gasket is tightly pressed between the cleaning door 301 and the opening, effectively filling the gap between them and forming a reliable seal.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
