[0002] In modern industrial production, laser cutting technology is widely used due to its advantages such as high precision and high speed. However, the laser cutting process produces a large amount of smoke and harmful gases, which, if not treated, will have a serious impact on the environment and the health of operators.

[0003] Traditional fume treatment methods remain inefficient and ineffective, failing to meet increasingly stringent environmental protection requirements and work environment quality standards. Therefore, a new, highly efficient and energy-efficient volumetric heat exchanger is needed to effectively purify laser cutting fume, ensuring a clean work environment and operator health while complying with environmental regulations. Utility Model Content

[0004] The main purpose of the present invention is to provide a novel high-efficiency and energy-saving volumetric heat exchanger, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A new type of high-efficiency and energy-saving volumetric heat exchanger includes a base plate and a discharge pipe. The right front end and the right rear end of the base plate are fixedly connected to handles, the four corners of the lower end of the base plate are fixedly connected to pulleys, a dust hood is fixedly installed on the right upper end of the base plate, a dust collection pipe is fixedly installed on the left end of the dust collection hood, and a purification box is fixedly installed on the end of the dust collection pipe away from the dust collection hood. The purification box is provided with a card slot on the upper front end and the upper rear end, and the two card slots are jointly connected with a card block, and the two card blocks are jointly fixedly connected with an upper cover.

[0007] A primary filter, a medium filter and a high efficiency filter are sequentially arranged inside the purification box. The left end of the primary filter is fixedly connected to four fixed blocks. The left ends of the four fixed blocks are commonly fixedly connected to a fan, and the exhaust pipe is connected to the air outlet of the fan.

[0008] Preferably, the dust hood is of side suction type or top suction type, and its shape and size are customized according to the working area of ​​the laser cutting equipment.

[0009] By adopting this technical solution, the customizable dust hood has significant benefits. With flexible options for side or top suction, the shape and size can be customized to suit the laser cutting equipment's working area, maximizing dust capture and improving dust collection efficiency, ensuring a clean working environment and protecting the health of operators.

[0010] Preferably, the dust collection hood is connected to the air inlet of the purification box through a dust collection duct, and the fan is installed at the air outlet of the purification box.

[0011] By adopting this technical solution, the beneficial effects of this connection method are obvious. The dust collection hood is connected to the air inlet of the purification box through the dust collection duct, ensuring effective dust transmission. The fan is installed at the air outlet of the purification box, providing stable wind power, accelerating air circulation, improving purification efficiency, making the entire system run more smoothly, and ensuring excellent purification results.

[0012] Preferably, the fan is a centrifugal fan, and its air volume and air pressure can be adjusted according to actual needs.

[0013] The above-mentioned technical solution, featuring a centrifugal fan with adjustable air volume and pressure, has shown significant benefits. It can adapt to varying dust loads and work scenarios, providing the appropriate wind speed on demand, ensuring efficient dust purification and reducing energy consumption. It also enhances the device's flexibility and applicability, safeguarding the air quality of the working environment.

[0014] Preferably, the dust collection pipe is made of a high temperature resistant and corrosion resistant material, such as stainless steel or polytetrafluoroethylene.

[0015] By adopting the above technical solution, the dust collection pipe is made of high-temperature and corrosion-resistant materials such as stainless steel or polytetrafluoroethylene, which has significant beneficial effects. It can work stably in harsh environments, extend service life, reduce maintenance costs, ensure stable dust transmission, and guarantee the long-term and effective operation of the entire purification device.

[0016] Preferably, the primary filter is a metal filter, the medium efficiency filter is a non-woven fabric filter, and the high efficiency filter is a HEPA filter.

[0017] By employing these technical solutions, this filter combination delivers significant benefits. The primary metal filter intercepts large particles, the mid-efficiency non-woven fabric filters small particles, and the high-efficiency HEPA filter removes microscopic particles. This multi-stage filtration synergistically achieves comprehensive and efficient purification, improving air cleanliness and safeguarding the work environment and personnel health.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the utility model, when working, smoke and dust are collected by a customized dust hood and sent to the purification box through the dust collection pipe. There are primary, medium and high efficiency filters in the box for multi-stage filtration, which intercept particles of different sizes respectively to achieve comprehensive purification. The filtered air is discharged through the exhaust pipe under the action of the centrifugal fan. The fan can adjust the air volume and air pressure as needed to ensure an efficient and smooth purification process. This multi-stage filtration and customized dust hood design greatly improves the purification effect, can remove various particles of smoke and dust, meets environmental protection standards, reduces environmental pollution, and the fan is adjustable to adapt to different scenarios and smoke amounts, ensuring that the device is flexible and applicable.

[0020] 2. In the present invention, the smoke generated by laser cutting is quickly sucked into the dust collection duct under the action of the side suction or top suction dust hood. The dust collection duct is made of high-temperature resistant and corrosion-resistant materials to ensure stability and durability in harsh working environments. After the smoke enters the purification box, the metal filter of the primary filter first filters out larger impurities, the non-woven fabric of the medium-efficiency filter further captures medium-sized particles, and the HEPA filter of the high-efficiency filter removes tiny particles and harmful substances. Finally, the purified air is discharged to a safe area through the exhaust duct under the strong suction force of the fan. This design can effectively protect the health of operators and prevent them from inhaling harmful smoke particles. The use of high-temperature resistant and corrosion-resistant dust collection duct materials extends the service life of the device and reduces maintenance costs. Moreover, the efficient purification effect helps to improve the overall air quality in the workplace and increase production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
