Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and particularly relates to an improved wind reduction and concentration increase mechanism. Background Art

[0002] A printing press is a machine for printing text and images. With the development of technology, printing equipment is moving towards automation and greening. Currently, electric heating is used to heat and dry materials, which consumes a lot of energy and has a high cost. In order to improve environmental protection performance, the hot water generated by the RTO waste gas treatment equipment in the workshop can be used to utilize the heat of this hot water, which can achieve energy saving and emission reduction on the one hand, and reduce the use cost of the equipment on the other hand. For example, the patent with publication number CN219856446U discloses a printing machine wind reduction and concentration device, including a support frame and a support mechanism, the support mechanism is installed on the support frame, and the support mechanism is provided with a wind reduction and concentration mechanism for reducing wind and increasing wind for the printing machine. The support mechanism includes a bottom plate, a support plate, a top plate and an extension plate. By replacing the wind box of the printing machine with a printing machine color position oven, and adding a wind reduction and concentration device to the color position oven of the printing machine, there are multiple heating methods. When the printing machine is performing step-by-step color printing, it can effectively achieve the drying effect by heat conversion to the oven heating to prevent a large amount of heat energy loss from failing to ensure the quality of the product. At the same time, the waste gas generated is processed by the RTO waste gas treatment equipment to form a cycle, and the control box uses a programmed PLC control with a high degree of automation, realizing no button operation and only operating the touch screen interface to start and use, which greatly improves the humanization and safety of the system.

However, when used for a long time, the circulating hot water may contain impurities. The impurities are easily accumulated during the circulation process inside the pipe, thereby causing blockage inside the pipe, reducing the circulating water pressure, shortening the life of the water pump, and reducing the thermal conductivity of the heat exchanger. In view of the shortcomings of the prior art, the utility model provides an improved air flow reduction and concentration increase mechanism to solve the above problems. Utility Model Content

When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0026] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0027] The embodiment of the present application provides an improved air reduction and concentration increasing mechanism to solve the problem that when the prior art equipment is used for a long time, the hot water circulating in the equipment may contain impurities, and the impurities are easily accumulated during the circulation process inside the pipe, thereby causing blockage inside the pipe, reducing the circulating water pressure, shortening the life of the water pump, and reducing the thermal conductivity efficiency of the heat exchanger.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The utility model embodiment discloses an improved wind reduction and concentration increasing mechanism, according to the attached Figure 1-4 As shown, it includes a support frame 1, on which a wind-reducing and concentration-increasing mechanism body 2 and an RTO exhaust gas treatment device 3 are installed, a water pipe body 4 is connected between the wind-reducing and concentration-increasing mechanism body 2 and the RTO exhaust gas treatment device 3, a water pump body 5 is provided on the water pipe body 4, and a filtering mechanism is provided on the water pipe body 4, and the filtering mechanism includes:

[0030] The filter box 6 is arranged on the top of the support frame 1 and connected to the water pipe body 4;

[0031] The vertical plate 7 is arranged in the inner cavity of the filter box 6, and a limiting frame 701 is arranged on the side of the vertical plate 7;

[0032] The filter plate 8 is movably connected to the cavity formed by the filter box 6, the vertical plate 7 and the limit frame 701;

[0033] The holder 9 is arranged on the filter plate 8 , and an interception net 901 is arranged on the holder 9 .

[0034] The main body 2 of the air reduction and concentration increase mechanism includes a heating box, an evaporator and a heating tube. The heating box is installed on the support frame 1. Two heating methods are arranged inside the heating box, one is water heating and the other is electric heating. The two heating methods are independent and can be controlled simultaneously. However, in order to save energy, the program formed by the design of PLC is first heated by water and then heated by electricity.

[0035] The inside of the heating box is respectively equipped with an evaporator and a heating tube. First, the hot water generated by the RTO waste gas treatment equipment 3 passes through the water pipe body 4 and flows to the ball valve actuator. The program formed by the optimization of the PLC is used to automatically adjust the size of the switch control amount to the surrounding of the evaporator. The evaporator structure is a finned coil to make the temperature uniform and keep the temperature in a balanced state. The biggest function is to increase the heating area and improve the heat transfer efficiency of the evaporator. The heat around the evaporator is extracted by controlling the inverter to adjust the speed of the fan through the touch screen. After the induction temperature of the thermocouple is confirmed, the program formed by the PLC calculates the temperature three times.

[0036] If the set temperature is not reached, the heating tube of the heating box is electrically heated for temperature compensation. There are multiple sets of heating tubes installed inside the heating box. The heating tube is controlled by a three-phase solid-state relay for heating. The temperature is sensed by the thermocouple and the program compiled by the PLC gives the voltage of the three-phase solid-state relay to control the heating of the heating tube. When the actual temperature is close to the set temperature to a certain value, the heating of the heating tube will be gradually reduced to prevent excessive temperature during the heating process.

[0037] Furthermore, a docking seat 601 is fixedly connected to the filter box 6, and an upper cover plate 602 is movably connected to the docking seat 601. The design of the docking seat 601 and the upper cover plate 602 facilitates closing the top opening of the filter box 6, thereby ensuring stable installation of the components inside the filter box 6.

[0038] Furthermore, a rubber ring 6021 is fixedly connected to the upper cover plate 602, and the rubber ring 6021 is used to seal the interface between the upper cover plate 602 and the docking seat 601. After the upper cover plate 602 is installed, the rubber ring 6021 is pressed tightly, and the rubber ring 6021 is deformed and seals the interface.

[0039] Furthermore, a clamping column 6022 is fixedly connected to the upper cover plate 602, and the clamping column 6022 is abutted against the holder 9. The design of the clamping column 6022 makes it convenient to use the clamping column 6022 to clamp and limit the position of the holder 9 and the filter plate 8 after the upper cover plate 602 is installed, so that the position of the holder 9 and the filter plate 8 can be stably installed and is not easy to loosen or shake.

[0040] It is particularly disclosed that the interception net 901 is made of stainless steel. Through the selection of the stainless steel material, the interception net 901 is not easy to rust and has a long service life.

[0041] Specifically, the docking seat 601 and the upper cover plate 602 are fixed at four corners by bolts, and the docking seat 601 and the upper cover plate 602 are easy to disassemble and assemble, thereby making it easy to load, disassemble and maintain the components inside the filter box 6.

[0042] The improved air reduction and concentration increase mechanism adopts a filtering mechanism design, and the filtering mechanism is installed at the front end of the water pump body 5, so as to filter the hot water transmitted inside the RTO exhaust gas treatment equipment 3 and intercept impurities, and prevent the impurities therein from entering the water pump body 5 and the heat exchanger pipe in the air reduction and concentration increase mechanism body 2, thereby improving the life of the device. The filter plate 8 in the filtering mechanism is easy to install, and subsequent disassembly, cleaning, maintenance and replacement are convenient, so that the filtering mechanism has good stability and meets the use requirements.

[0043] When installing the filter plate 8, first directly snap the filter plate 8 into the cavity formed by the filter box 6, the vertical plate 7 and the limit frame 701, then snap the base 9 and the interception net 901 onto the top of the filter plate 8, and use the base 9 and the interception net 901 to intercept larger impurities to facilitate subsequent cleaning, finally dock the upper cover 602 with the docking seat 601, and tighten them with bolts. After tightening, the tightening column 6022 clamps and limits the base 9 and the filter plate 8, and the rubber ring 6021 is squeezed and seals the interface between the upper cover 602 and the docking seat 601.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
