Detailed Implementation
[0020] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0021] Example 1
[0022] like Figure 1 As shown, Figure 1 This is a front view of the structure of the heating device suitable for compressed air.
[0023] The heating device for compressed air according to this utility model includes a heating chamber 1. A first partition plate 2 and a second partition plate 3 are provided inside the heating chamber 1. The first partition plate 2 and the second partition plate 3 divide the inner cavity of the heating chamber 1 into an air inlet chamber 11, a heating chamber 12, and an air outlet chamber 13 arranged sequentially. An air inlet pipe 7 and an air outlet pipe 8 are provided on the heating chamber 1. The air inlet pipe 7 is positioned corresponding to and communicating with the air inlet chamber 11, and the air outlet pipe 8 is positioned corresponding to and communicating with the air outlet chamber 13. The heating chamber 12 is connected to the first partition plate 2 and the second partition plate 3 respectively. The air inlet chamber 11 and the air outlet chamber 13 are connected through the hollow cavity of the heat exchange tube 4. The space between the heating chamber 12 and the heat exchange tube 4 is filled with a heating medium. The heating chamber 12 is equipped with a heater 5 to heat the heating medium. The air inlet chamber 11 and the air outlet chamber 13 are equipped with condensing plates 6 so that the moisture in the compressed air can be collected on the condensing plates 6.
[0024] The heating medium is generally set as fully synthetic oil, and the maximum heating temperature of the fully synthetic oil is above 150°C, which can effectively heat the moisture in the compressed air to 100°C for vaporization.
[0025] Specifically, the outer edges of the first partition plate 2 and the second partition plate 3 are sealed to the inner wall of the heating box 1, thereby ensuring effective separation between the chambers by the first partition plate 2 and the second partition plate 3. Both the first partition plate 2 and the second partition plate 3 are provided with connection holes, and the heat exchange tube 4 is disposed in the corresponding connection hole and the connection hole is sealed to the outer wall of the heat exchange tube 4, thereby ensuring that the heat exchange tube 4 is sealed and isolated inside and outside, and the inside of the heat exchange tube 4 is connected to the air inlet chamber 11 and the air outlet chamber 13.
[0026] Preferably, the heating device for compressed air further includes a sensor 9 and a control box 10. The probe of the sensor 9 is disposed in the heating chamber 12 to detect the temperature of the heating medium. The control box 10 is connected to both the heater 5 and the sensor 9 to control the heating efficiency of the heater 5 in real time based on the temperature data detected by the sensor 9, so as to ensure the temperature of the heating medium is stable.
[0027] This invention heats the compressed air in the heat exchange tube 4 with the heating medium, causing the moisture in the compressed air to vaporize. The moisture in the compressed air is cooled and condensed through contact with the condenser plate 6, thereby significantly reducing the moisture content in the compressed air. This effectively prevents the compressed air transport pipeline from freezing and becoming blocked, and also reduces the mixing and clumping of moisture with dust in the dust collector.
[0028] Example 2
[0029] like Figure 2 As shown, Figure 2 The diagram shows a cross-sectional view of the heating chamber. The heating chamber 12 contains two sets of pipe groups, which are symmetrically arranged on both sides of the heating rod 51 of the heater 5. Each pipe group includes several heat exchange tubes 4, and the heat exchange tubes 4 of the same pipe group are arranged in a straight line in the vertical direction, thereby ensuring that the heater 5 heats the heating medium around each heat exchange tube 4 uniformly.
[0030] Preferably, the heating chamber 1 is provided with a vent 14 corresponding to the heating chamber 12. The vent 14 is located above the heating chamber 1 and connects the heating chamber 12 to the outside, so as to prevent the heating chamber 12 from being sealed and to ensure that the pressure of the heating medium in the heating chamber 12 is stable within a large temperature range.
[0031] Example 3
[0032] Both the air inlet chamber 11 and the air outlet chamber 13 are provided with drain pipes 15 at their bottoms. Each drain pipe 15 is equipped with a drain valve 16. The water condensed and collected by the condenser plate 6 falls to the bottom of the air inlet chamber 11 or the air outlet chamber 13 under its own gravity. By controlling the drain valve 16 to open and close the drain pipe 15, the water at the bottom of the air inlet chamber 11 and the air outlet chamber 13 is discharged.
[0033] The condenser plate 6 is vertically arranged in the corresponding air inlet chamber 11 and air outlet chamber 13. The condenser plate 6 is a rectangular plate, and there are gaps between the four sides of the condenser plate 6 and the inner wall of the heating box 1. The compressed air entering through the air inlet pipe 7 and the compressed air exiting through the air outlet pipe 8 are both diverted through the condenser plate 6 to improve the gas flow path and facilitate contact and condensation with the condenser plate 6. At the same time, it also ensures that the compressed air enters each of the heat exchange tubes 4 evenly.
[0034] like Figure 3 As shown, Figure 3 This is a cross-sectional view of the air intake chamber. Specifically, a condensation channel 61 is provided inside the condensing plate 6. An inlet pipe 62 and an outlet pipe 63 are fixedly provided at the top of the condensing plate 6. The inlet pipe 62 and the outlet pipe 63 are respectively provided at both ends of the condensation channel 61. The inlet pipe 62 and the outlet pipe 63 are fixedly provided on the heating box 1. The condensate flows into the condensation channel 61 through the inlet pipe 62 and flows out of the condensation channel 61 through the outlet pipe 63, thereby ensuring the condensation temperature of the condensing plate 6.
[0035] Compressed air entering through the air inlet pipe 7 or compressed air heated by the heat exchange pipe 4 comes into contact with the condenser plate 6 at a lower temperature, thereby achieving rapid condensation and liquefaction on the condenser plate 6, and sliding down under its own gravity to collect at the bottom of the heating box 1.
[0036] Preferably, the condensation channel 61 within the condensation plate 6 extends along an S-shaped or U-shaped curve to increase the coverage area of the condensation channel 61 on the condensation plate 6, thereby ensuring uniform temperature on the condensation plate 6.
[0037] Generally, a support column 64 is provided at the bottom of the condenser plate 6. The top end of the support column 64 is connected to the condenser plate 6, and the bottom end is fixedly connected to the inner wall of the heating box 1, thereby improving the stability of the condenser plate 6 in the heating box 1 to resist the impact of compressed air.
[0038] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
