Description

Technical Field

[0001] This application relates to the field of workshop ventilation technology, specifically to a ventilation and air exchange device for a paint production workshop. Background Technology

[0002] In paint production workshops, the production process generates large amounts of volatile organic compounds, dust, and various odors, resulting in poor air quality. If these polluting gases are released directly outside the workshop without effective treatment, they will pollute the surrounding air environment, affecting the lives and health of nearby residents. Furthermore, traditional ventilation equipment has many shortcomings. For example, the use of large-sized fans to meet ventilation demands leads to high equipment costs and energy consumption; fixed installations prevent flexible adjustments to areas with concentrated odors, resulting in widespread odor diffusion; unreasonable equipment design makes components prone to movement due to airflow, reducing ventilation efficiency; and low reliability of the ventilation system means that a single fan failure can severely impact ventilation capacity.

[0003] Therefore, there is a need for ventilation equipment in paint production workshops that can effectively purify the air, reduce costs and energy consumption, flexibly respond to odor distribution, have a stable structure, and provide reliable ventilation. Summary of the Invention

[0004] In response to the aforementioned technical problems, this application solves the problems of poor ventilation and low efficiency in existing paint production workshops.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a ventilation and air exchange device for a paint production workshop, comprising a main frame, an outer shell fixedly installed on the main frame, an outer support frame and an outer filter screen fixedly installed on the outer shell, two rotating shafts rotatably arranged on the outer support frame, a fan fixedly installed on each rotating shaft, a side plate slidably installed on the main frame, multiple mounting plates provided on the side plate, grooves provided on the mounting plates, honeycomb activated carbon placed in the grooves, and a top rod fixedly installed on the main frame.

[0006] Preferably, a connecting seat is fixedly provided on the main frame, and the connecting seat is provided with three grooves, on which a slide is fixedly installed.

[0007] Preferably, a plurality of support blocks are fixedly provided on the side plate, and the support blocks are provided with grooves for mounting the mounting plate. A bottom plate and an inner filter screen are fixedly provided on the side plate, and the inner filter screen is located at one end of the side plate near the top rod.

[0008] Preferably, a battery, an electronic control unit, and a motor are fixedly mounted on the inner support frame, and the output end of the motor is fixedly connected to the rotating shaft.

[0009] Preferably, an inner shell is fixedly installed on the inner support frame, and the inner shell is fixedly connected to the outer filter and the outer shell, with the inner shell separating the gas flow channels inside the outer shell.

[0010] The technical solution provided in this application has the following advantages compared with the prior art:

[0011] 1. This application uses a top rod filter to block larger dust particles floating in the workshop, and uses honeycomb activated carbon to adsorb odors and toxic pollutants such as toluene and formaldehyde, which can effectively purify the gas discharged from the workshop, avoid polluting the air outside the workshop, and ensure the air quality around the factory.

[0012] 2. The outer casing of this application is designed in a trapezoidal shape, with the narrow opening facing the exhaust direction. By guiding the gas through the gradually narrowing channel, a smaller fan can be used to drive the gas flow within the main frame, reducing equipment production costs while achieving better ventilation and energy saving.

[0013] 3. The main frame of this application can slide on the window frame via rollers on the connecting seat and the slide, making it convenient to approach production equipment that generates a lot of odor in the workshop, improving the efficiency of odor removal, and effectively reducing the spread of odor in the workshop.

[0014] 4. In this application, the side panel is installed and fixed using a support block, a base plate, and an internal filter screen. The side panel is initially supported by a mounting plate, and then the base plate, which is longer than the mounting plate, and the internal filter screen ensure a tight fit between the side panel and the main frame, increasing friction and preventing airflow from causing the side panel to move, thus ensuring the stability of the equipment structure.

[0015] 5. The inner shell of this application divides the gas flow channel within the outer shell into two air ducts, each corresponding to a fan. When one fan fails, the other fan can still operate normally, and the air ducts are unaffected, thus not reducing the ventilation effect and ensuring the reliability of ventilation.

[0016] 6. This application uses a storage battery to provide power to the motor and controls the motor rotation through an electronic control unit, thereby achieving convenient control of the fan without relying on complex external power supply lines, which enhances the flexibility of equipment use.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] like Figures 1 to 6 As shown, a ventilation and air exchange device for a paint production workshop includes a main frame 101. A housing 105 is fixedly installed on the main frame 101. An outer support frame 108 and an outer filter screen 106 are fixedly installed on the housing 105. Two rotating shafts 109 are rotatably arranged on the outer support frame 108. A fan 110 is fixedly installed on each rotating shaft 109. A side plate 115 is slidably installed on the main frame 101. Multiple mounting plates 116 are provided on the side plate 115. The mounting plates 116 are provided with grooves, and honeycomb activated carbon 117 is placed in the grooves. A top rod 120 is fixedly installed on the main frame 101.

[0027] Specifically, the ventilation equipment of this application is installed on the window frame of the workshop wall, with the top rod 120 facing the inside of the workshop and the outer casing 105 facing the outside of the workshop. The rotation of the fan 110 generates airflow, allowing the air in the workshop to pass through the top rod 120 and the honeycomb activated carbon 117, and then be discharged to the outside of the workshop through the outer support frame 108. The top rod 120 filters and blocks larger floating particles such as dust in the workshop, and the multiple honeycomb activated carbon 117 adsorb odors and remove pollutants such as toluene and formaldehyde from the air in the workshop. Then, guided by the outer casing 105, the air is discharged to the outside through the outer support frame 108, thus outputting relatively clean air, avoiding air pollution outside the workshop, and ensuring the air quality around the factory.

[0028] like Figure 1 As shown, the outer casing 105 is trapezoidal in shape, with the narrow opening of the outer casing 105 facing the exhaust direction and the wide opening facing the air intake direction in the workshop. By using the gradually narrowing channel, the gas is guided, so that a smaller fan 110 can be used to drive the gas flow within the frame of the main frame 101, thereby reducing the production cost of the equipment.

[0029] like Figure 3 As shown, a connecting seat 103 is fixedly installed on the main frame 101. The connecting seat 103 has three grooves, and a slide 104 is fixedly installed on each groove. The slide 104 is provided with rollers and a sliding groove, so that when the main frame 101 is pushed, the rollers of the slide 104 can slide on the window frame to move its position. For production equipment that generates a lot of odor in the workshop, the ventilation and air exchange equipment of this application is placed closer to the production equipment, thereby improving the odor removal efficiency and reducing the diffusion range of odor in the workshop.

[0030] A connecting seat 103 is fixedly installed on the main frame 101 of this ventilation and air exchange equipment. A groove on the connecting seat 103 is used to install a sliding block 104. The sliding block 104 is cleverly equipped with rollers and sliding grooves, a design that gives the entire equipment excellent mobility. When the equipment position needs to be adjusted, the operator only needs to gently push the main frame 101, and the rollers of the sliding block 104 will slide smoothly on the window frame, thus moving the equipment on the window frame. This design overcomes the limitations of traditional fixed-installation ventilation equipment, allowing the equipment to be flexibly repositioned according to the actual needs of the workshop.

[0031] In paint production workshops, different production equipment generates odors at varying degrees and locations during operation. Some large mixing equipment or spray painting areas may produce significant amounts of odor, and traditional fixed ventilation equipment struggles to effectively ventilate these specific areas. The mobility of this equipment perfectly solves this problem. When a paint mixing machine emits a strong odor during production, workers can quickly move the ventilation equipment closer to the machine, bringing the air inlet closer to the odor source, thus more efficiently capturing and expelling the odorous gases. This flexible mobility greatly enhances the equipment's adaptability to complex odor distribution within the workshop, meeting the ventilation needs of different production scenarios.

[0032] like Figure 2 and Figure 3 As shown, a plurality of support blocks 121 are fixedly provided on the side plate 115. The support blocks 121 are provided with mounting grooves for mounting plates 116. A bottom plate 118 and an inner filter screen 119 are fixedly provided on the side plate 115. The inner filter screen 119 is located on the side plate 115 near the top rod 120.

[0033] Specifically, the side plates 115 on both sides are supported by the base plate 118 and the inner filter 119. The upper inner filter 119 is located on the side plate 115 near the top rod 120, thus avoiding interference with the installation of the honeycomb activated carbon 117 and the mounting plate 116. In use, the side plates 115 on both sides are placed on the inner wall of the main frame 101, and then the mounting plate 116 and the honeycomb activated carbon 117 are installed. The mounting plate 116 initially supports the side plates 115 on both sides. Then, the side plates 115 are pushed to slide and move to a suitable position. Then, the base plate 118 and the inner filter 119 are installed. The length of the base plate 118 and the inner filter 119 is greater than the length of the mounting plate 116, so that the side plates 115 move a certain distance to both sides, so that the side plates 115 fit tightly against the main frame 101, forming a large friction force to fix the side plates 115 and prevent the airflow from moving the side plates 115.

[0034] like Figure 2 and Figure 5 As shown, a battery 112, an electronic control unit 113, and a motor 114 are fixedly mounted on the inner support frame 107. The output end of the motor 114 is fixedly connected to the rotating shaft 109. Specifically, the battery 112 provides power to the two motors 114, and the program of the electronic control unit 113 controls the rotation of the motors 114. In turn, the motors 114 drive the rotating shaft 109 and its fan 110 to rotate, forming a gas flow.

[0035] A battery 112, fixedly mounted on the inner support frame 107, provides power for the operation of the entire ventilation system. Compared to traditional power supply methods that rely on complex wiring in the workshop, battery power supply has significant advantages. Firstly, it eliminates the limitation of specific power outlet locations, allowing for more flexible installation. The equipment's position on the window frame can be adjusted more freely according to the actual ventilation needs of the workshop, without worrying about the length and layout of power lines. Secondly, the battery has a certain energy storage capacity, ensuring that the equipment can continue to operate for a period of time even in the event of a short power outage, guaranteeing uninterrupted ventilation and maintaining stable air quality within the workshop.

[0036] The electronic control unit 113, as the core of the equipment's control, precisely controls the rotation of the motor 114 through a preset program. Operators can easily regulate the operation of the fan 110 via the electronic control unit, such as starting, stopping, and adjusting its speed. This intelligent control method greatly improves the ease of use of the equipment. During workshop production, if a sudden increase in odor concentration is detected in a certain area, staff can quickly increase the fan speed through the electronic control unit to enhance the ventilation efficiency of that area. Furthermore, the electronic control unit can be timed according to actual needs, such as automatically reducing the fan speed to a low-power mode after the workshop closes, ensuring sufficient ventilation to maintain fresh air while effectively saving energy. Simultaneously, the electronic control unit has good compatibility and can be easily integrated with other environmental monitoring systems in the workshop to achieve data sharing and collaborative control, further enhancing the intelligent level of workshop environmental management.

[0037] like Figure 5 As shown, an inner shell 111 is fixedly installed on the inner support frame 107. The inner shell 111 is fixedly connected to the outer filter screen 106 and the outer shell 105, and the inner shell 111 separates the gas flow channel inside the outer shell 105. Specifically, as shown... Figure 2 and Figure 5 As shown, the inner shell 111 has a bent end near the top rod 120, with the tip pointing towards the top rod 120. This allows gas entering the outer shell 105 to be guided by the tip of the inner shell 111 and its beveled surface, forming two airflows, one above the other. Each of the two fans 110 forms its own air duct, and both ducts use the same inlet (top rod 120) and one outlet (outer support frame 108). By using two separate air ducts, if one fan 110 malfunctions, the other can still function normally without affecting the air ducts or ventilation capacity. Without these separate air ducts, the airflows would interfere with each other, reducing ventilation efficiency.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
