Description

Technical Field

[0001] This utility model relates to the field of dust particle treatment technology, specifically to an adaptively adjustable dust particle treatment device for EVA production. Background Technology

[0002] Dust particle treatment devices utilize technologies such as mechanical filtration, electrostatic adsorption, wet scrubbing, or baghouse dust collection to effectively intercept particles ranging from micrometers to millimeters, preventing their diffusion into the workplace or emission into the atmosphere. This not only significantly improves air quality in the work environment, protects employees' respiratory health, and reduces the risk of occupational diseases, but also helps companies meet the stringent environmental regulations on dust emissions, avoiding legal penalties and ecological damage caused by excessive emissions.

[0003] However, existing dust particle treatment devices suffer from reduced interception efficiency. Although internal baffles are installed to optimize treatment, these baffles are fixed structures and cannot be flexibly adjusted according to actual operating conditions (such as dust concentration and particle size). Fixed baffles make it difficult for the device to dynamically adapt to the optimal airflow velocity when dealing with different dust concentrations, preventing internal components from fully utilizing their synergistic effect and resulting in unnecessary energy consumption.

[0004] This also leads to a decrease in dust collection rate and a weakening of purification effect. Under long-term operation, this mismatch further aggravates equipment wear and increases maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive dust particle treatment device for EVA production, which monitors the dust concentration and distribution inside the device in real time, and can automatically optimize the airflow path according to changes in dust concentration, ensuring collection efficiency at high concentrations and reducing energy consumption at low concentrations, thereby improving dust treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptively adjustable dust particle handling device for EVA production, comprising a dust handling device body and a motor fixed to the inner wall of the dust handling device body, and further comprising:

[0007] A transmission mechanism is installed in the inner cavity of the dust treatment device body. A dust detection device is installed on the surface of the transmission mechanism. A locking mechanism is installed in the inner cavity of the dust treatment device body. A particle detector is fixed on the inner wall of the dust treatment device body.

[0008] Preferably, the transmission mechanism includes:

[0009] A pushing block slides on the inner wall of the dust handling device body. A meshing block is fixed on the surface of the pushing block, and a threaded rod is engaged in the inner cavity of the meshing block.

[0010] Preferably, the locking mechanism includes:

[0011] A sleeve is fixed to the inner wall of the push block. A spring is fixed to the inner wall of the sleeve. A push rod is fixed to the other end of the spring. A locking block is fixed to the other end of the push rod.

[0013] Preferably, one end of the card block is a triangular pyramid, and the inclination angle of the inclined surface is the same as the inclination angle of the air outlet plate.

[0014] Preferably, the motor is a servo motor and has a built-in brake device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention employs a transmission mechanism and a locking mechanism, enabling the dust detection device to monitor the dust concentration and distribution within the device in real time and feed the data back to the control system. The system then drives the transmission mechanism based on the feedback information to precisely adjust the internal passage structure. Simultaneously, the locking mechanism locks the optimized passage state. This adaptive adjustment mechanism allows the device to automatically optimize the airflow path according to changes in dust concentration, ensuring high collection efficiency at high concentrations and reducing energy consumption at low concentrations. This significantly improves dust treatment efficiency and achieves dual optimization of purification effect and energy utilization. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-6 As shown, an adaptive dust particle handling device for EVA production includes a dust handling device body 1, a transmission mechanism 2 is provided in the inner cavity of the dust handling device body 1, a dust detection device 3 is provided on the surface of the transmission mechanism 2, a motor 4 is fixed on the inner wall of the dust handling device body 1, a locking mechanism 5 is provided in the inner cavity of the dust handling device body 1, and a particle detector 6 is fixed on the inner wall of the dust handling device body 1.

[0026] The dust treatment device body 1 includes an externally installed air pump for providing a powerful airflow to blow dust off the surface of the plastic particles and discharge it, an airflow filter plate for airflow to pass through but to block dust from entering, thereby preventing dust from other parts from entering, an inlet and an outlet for the entry and exit of plastic particles, and a corresponding device is placed at the outlet to detect the discharge speed in real time.

[0027] The transmission mechanism 2 is located inside the body 1 of the dust treatment device and is used to control the position of its internal structure by rotating through threaded engagement, so as to adjust the cross-sectional area of ​​the airflow channel and thereby change the airflow speed flowing through the treatment device.

[0028] The transmission mechanism 2 includes a push block 23 that slides on the inner wall of the dust treatment device body 1. A meshing block 22 is fixed on the surface of the push block 23. A threaded rod 21 meshes in the inner cavity of the meshing block 22. When the dust-laden airflow hits the push block 23, the dust is captured by the inertia of the airflow. The higher the speed, the greater the inertia, and the higher the capture efficiency.

[0029] The threaded rod 21 is fixed to the output end of the motor 4. Driven by the motor 4, it rotates continuously, causing the meshing block 22 on it to move, thereby changing the position of the push block 23 and realizing the adjustment of the cross-sectional area of ​​the airflow channel.

[0030] The meshing block 22 is fixed to the surface of the push block 23 to increase the meshing area, thereby ensuring smooth pushing during continuous meshing and avoiding displacement caused by resistance.

[0031] The pusher block 23 slides against the inner wall of the dust treatment device body 1, changing its position to change the cross-sectional area of ​​the airflow channel, thereby adjusting the speed of the airflow.

[0032] The dust detection device 3 is fixed to the surface of the push block 23. By detecting the dust density in the space in real time, it transmits the signal to the PLC in real time, so that the signal can be transmitted to the motor 4 to control its operation.

[0033] The motor 4 is fixed to the inner wall of the dust treatment device body 1. By rotating continuously, it transmits power to the surface of the push block 23, enabling it to drive the internal components to move and change the size of the passage.

[0034] Motor 4 is a servo motor with a built-in brake device, which can precisely control its rotation and thus more accurately adjust the position of the push block 23.

[0035] The positioning mechanism 5 is located in the inner cavity of the dust treatment device body 1. When the pushing block 23 is continuously pushed to move, the positioning mechanism 5 changes shape to adapt to the internal structure, ensuring smooth airflow and avoiding dust removal errors caused by airflow.

[0036] The locking mechanism 5 includes a sleeve 51 fixed to the inner wall of the push block 23, a spring 52 fixed to the inner wall of the sleeve 51, a push rod 53 fixed to the other end of the spring 52, and a locking block 54 fixed to the other end of the push rod 53.

[0037] The sleeve 51 is fixed to the inner wall of the push block 23 to limit the sliding of the internal push rod 53 and to provide position for the expansion and contraction of the spring 52, ensuring that the push rod 53 can stably control the movement of the locking block 54.

[0038] Spring 52 is fixed to one end of push rod 53. By continuously releasing elastic force, the locking block 54 is kept in close contact with the internal structure of the dust treatment device body 1, thereby stabilizing its channel airtightness.

[0039] The spring 52 is made of stainless steel and its diameter is similar to the inner diameter of the push rod 53. It can be repeatedly compressed and released, and its strong metal fatigue resistance can greatly extend its service life.

[0040] The push rod 53 slides on the inner wall of the sleeve 51 to transmit the elastic force to the surface of the locking block 54 and to the surface of other components.

[0041] The locking block 54 slides on the inner wall of the pushing block 23, and by moving, it changes the overall shape of the pushing block 23, thereby enabling it to fully adapt to the internal layout of the equipment.

[0042] One end of the card block 54 is a triangular pyramid, and the angle of inclination of the inclined surface is the same as the angle of inclination of the air outlet plate, to ensure smooth sliding and avoid gaps that could allow dust to enter.

[0043] The particle detector 6 is fixed to the inner wall of the dust treatment device body 1. It is used to detect the particle density at the outlet and transmit the information to the PLC. The PLC summarizes the information and transmits it to the motor 4 to control its operation.

[0044] Working principle: During the dust cleaning process, when the dust detection device 3 detects an increase in internal dust concentration and the particle detection device detects an increase in output particle quantity, it will transmit a signal to the PLC, which will then transmit the signal to the motor 4. At this time, the motor 4 starts and drives the threaded rod 21 to rotate. With the continuous rotation of the threaded rod 21, the meshing block 22 gradually drives the pushing block 23 to move under the continuous meshing action, thereby reducing the cross-sectional area of ​​the airflow passage, thereby increasing the speed of the airflow and enhancing the centrifugal or inertial capture effect of dust. Because the cross-sectional area of ​​the passage is reduced, the airflow resistance increases, the airflow speed increases, the inertial force / centrifugal force on the dust is enhanced, and the capture efficiency is improved.

[0045] As the push block 23 moves continuously, the spring 52 continuously releases its elastic force. Under the push of the spring 52, the push rod 53 is pushed downward. As the push rod 53 moves, the locking block 54 moves diagonally downward under the combined action of the motor 4 and the spring 52, thus achieving a complete fit even on the inclined surface.

[0046] When the dust concentration decreases, the system controls motor 4 to reverse, increasing the cross-sectional area of ​​the passage to reduce airflow resistance, reduce airflow speed, and decrease fan energy consumption, resulting in significant energy savings. This reduces the energy consumption of power equipment such as fans and dynamically changes the airflow speed by adaptively adjusting the cross-sectional area of ​​the airflow passage, thereby minimizing the output energy consumption of internal equipment without affecting the dust removal effect, achieving dual optimization of purification effect and energy utilization.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
