Description

Technical Field

[0001] This utility model relates to the field of dust collection device technology, and in particular to a dust collection device for grinding aggregates in concrete. Background Technology

[0002] The production process of concrete admixture and aggregate grinding generates a large amount of dust and particulate matter. This dust not only pollutes the working environment but also harms the health of operators. Therefore, dust collection devices play a crucial role in concrete admixture and aggregate grinding equipment.

[0003] First, the fixed position and angle of the suction head in traditional dust collection devices cannot be adjusted according to the actual working environment, resulting in unsatisfactory dust collection effect. In the complex process of concrete mixing and stone grinding, the distribution of dust and particulate matter is often uneven. The fixed position and angle of the suction head cannot cover all areas where dust is generated, thus affecting the dust collection efficiency. Second, the filter frame of traditional dust collection devices is inconvenient to install and disassemble, and the cleaning and maintenance work is cumbersome. The filter frame is an important component in the dust collection device used to filter dust and particulate matter. It needs to be cleaned and replaced regularly to maintain its filtering effect. However, the traditional filter frame design often makes the cleaning and replacement process complicated and time-consuming, increasing the burden on operators.

[0004] Therefore, in order to address this problem, this utility model provides a dust collection device for grinding aggregates used in concrete admixtures. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-4A dust collection device for grinding aggregates used in concrete admixtures is disclosed. The device mainly consists of a collection box 1. A base 2 is mounted on top of the collection box 1, supporting and adjusting the position of the dust collection component. An adjusting frame 3 is flexibly connected to the top of the base 2 via a pivot, allowing the adjusting frame 3 to rotate freely within a certain range to adapt to different dust collection needs. An angle adjusting disc 4 is equipped on the side of the base 2. Rotating the angle adjusting disc 4 further adjusts the angle of the adjusting frame 3. To ensure stability after adjustment, a limit pin 5 is threadedly connected between the base 2 and the angle adjusting disc 4 to fix the adjusting frame 3 at the desired angle. The top of the adjusting frame 3 is designed with a sliding connection structure for connecting an extension frame 6. The frame 6 can slide along the length of the adjustable frame 3 to adjust the position of the suction head 8. To lock the position of the extension frame 6, the side of the adjustable frame 3 is equipped with a threaded fixing pin 7. The suction head 8 is installed at one end of the extension frame 6 and is connected to the sealing cover 11 on the top of the collection box 1 through the connecting pipe 9. The collection box 1 is equipped with a sliding filter frame 10 for filtering the sucked-in dust. The top of the sealing cover 11 is equipped with a cover handle 12 for easy opening, and the back of the collection box 1 is equipped with an exhaust pipe for discharging the filtered air. This dust collection device effectively improves the dust collection efficiency through flexible angle and position adjustment, while the built-in filter frame 10 ensures that the collected dust does not escape, maintaining the cleanliness of the working environment.

[0023] The inner wall of the collection box 1 is designed with a slot 101. Correspondingly, the filter frame 10 is symmetrically provided with a seat 1001 on both sides. When the filter frame 10 is inserted into the collection box 1, the seat 1001 will slide along the slot 101 until it is fully installed. This design not only facilitates the quick installation and disassembly of the filter frame 10, but also ensures the stability of the filter frame 10. Through the cooperation of the slot 101 and the seat 1001, the replacement and cleaning of the filter frame 10 becomes simpler and improves work efficiency.

[0024] Among them, symmetrical pull handles 1002 are arranged on the inner wall of the filter frame 10. When it is necessary to remove or install the filter frame 10, the staff can easily hold the pull handles 1002 and easily pull the filter frame 10 out of the collection box 1 or push it in. The design of the pull handles 1002 makes the operation of the filter frame 10 more user-friendly and reduces the difficulty of operation.

[0025] Among them, wheel frames 102 are symmetrically installed on both sides of the bottom of the collection box 1, and each wheel frame 102 is equipped with a universal wheel 103. This design allows the entire dust collection device to be easily moved on the ground, making it convenient to move between different work locations. By equipping the universal wheel 103, the mobility of the dust collection device is greatly enhanced, improving the flexibility of use.

[0026] The angle adjustment disc 4 has several adjustment slots 401 evenly spaced on its side, which are threadedly connected to the limit pins 5. By rotating the angle adjustment disc 4 and selecting the appropriate adjustment slot 401, the adjustment frame 3 can be fixed at the desired angle. Then, the limit pins 5 are tightened to ensure stability. The cooperation between the adjustment slots 401 and the limit pins 5 makes the angle adjustment more precise and stable, meeting the needs of different working environments.

[0027] The side of the adjustment frame 3 is equipped with a locking sleeve 301, and the fixing pin 7 is connected to the locking sleeve 301 by a threaded connection. When the extension frame 6 is adjusted to the appropriate position, tightening the fixing pin 7 will lock it in that position. The design of the locking sleeve 301 and the fixing pin 7 makes the position adjustment of the extension frame 6 more reliable, ensuring that the vacuum head 8 can work stably in the predetermined position.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
