[0003] Vacuum rehumidifiers are key equipment in the tobacco processing industry, mainly used for heating and humidifying tobacco leaves. During the vacuum rehumidification process, a large amount of high-temperature condensate is generated. Traditional collection methods cannot achieve automatic discharge of condensate. Therefore, we propose a condensate collection device for vacuum rehumidifiers. Utility Model Content

[0004] In view of the problem that the existing collection methods cannot achieve automatic discharge of condensate, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A condensate collection device for a vacuum dehumidifier includes a collection box, the top of which is equipped with a condensate inlet connected to the vacuum dehumidifier, and the bottom of which is equipped with a condensate drain outlet connected to the collection box.

[0007] A release cylinder is coaxially mounted on the bottom wall of the inner cavity of the collection box with the condensate drain outlet. The outer surface of the release cylinder has through holes arranged in a linear circumferential array.

[0008] A float mechanism, comprising a counterweight cylinder slidably sleeved on the outer surface of the release cylinder, a connecting rod mounted on the top of the counterweight cylinder, and a float body mounted on the end of the connecting rod away from the counterweight cylinder.

[0009] As a technical solution of the vacuum rehumidifier condensate collection device of this utility model, the outer surface of the release cylinder is provided with guide grooves arranged in a circular array, and the inner wall of the counterweight cylinder is equipped with sliders corresponding to the guide grooves respectively, and the sliders are adapted to the guide grooves. The counterweight cylinder is slidably installed on the release cylinder through the sliders and the guide grooves.

[0010] As a technical solution of the vacuum rehumidifier condensate collection device of this utility model, wherein: an upper limit ring for limiting the detachment of the counterweight cylinder is installed on the top outer surface of the release cylinder, and an arc-shaped sealing section is installed on the adjacent slider and the inner wall of the counterweight cylinder.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model uses a float to sense changes in water level, which drives the counterweight cylinder to move up and down to automatically control the opening and closing of the through hole, thus realizing the automatic discharge function of condensate.

Counterweight cylinder; 301. Sliding block; 302. Arc-shaped sealing section; 4. Connecting rod; 5. Float. Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-4 A condensate collection device for a vacuum dehumidifier is provided. The condensate collection device includes a collection box 1. A condensate inlet 101 connected to the vacuum dehumidifier is installed on the top of the collection box 1. A condensate drain outlet 102 connected to the collection box 1 is installed on the bottom of the collection box 1.

[0026] Release cylinder 2 is coaxially mounted on the bottom wall of the inner cavity of the collection box 1 with the condensate drain outlet 102. The outer surface of the release cylinder 2 is provided with through holes 202 arranged in a linear circumferential array.

[0027] The float mechanism includes a counterweight cylinder 3 that is slidably sleeved on the outer surface of the release cylinder 2. A connecting rod 4 is installed on the top of the counterweight cylinder 3, and a float body 5 is installed at the end of the connecting rod 4 away from the counterweight cylinder 3. In application, the float body 5 senses the water level change and drives the counterweight cylinder 3 to move up and down to automatically control the opening and closing of the through hole 202, thereby realizing the automatic discharge function of condensate water. This solves the problem that traditional methods cannot automatically discharge condensate water. At the same time, the structure is relatively simple and easy to manufacture and maintain.

[0028] Reference Figures 2-4The outer surface of the release cylinder 2 is provided with guide grooves 201 arranged in a circumferential array. The inner wall of the counterweight cylinder 3 is equipped with sliders 301 that correspond to the guide grooves 201 respectively, and the sliders 301 are adapted to the guide grooves 201. The counterweight cylinder 3 is slidably installed on the release cylinder 2 through the sliders 301 and the guide grooves 201. In application, it provides precise guidance for the sliding of the counterweight cylinder 3 on the release cylinder 2, ensuring that it can only move up and down smoothly and steadily in the vertical direction, preventing deviation or jamming. At the same time, it improves the reliability and stability of the float mechanism and ensures the accuracy of drainage control.

[0029] Reference Figures 2-4 The upper limit ring 203 is installed on the top outer surface of the release cylinder 2 to limit the counterweight cylinder 3 from disengaging. The adjacent slider 301 and the inner wall of the counterweight cylinder 3 are equipped with arc-shaped sealing sections 302. In application, the upper limit ring 203 can effectively prevent the counterweight cylinder 3 from accidentally disengaging from the release cylinder 2 during the rising process, which improves the safety and durability of the device. The arc-shaped sealing section 302 lays the foundation for the subsequent sealing function.

[0030] Reference Figures 2-4 The radius of curvature of the arc-shaped sealing section 302 is adapted to the inner diameter of the release cylinder 2. When the counterweight cylinder 3 is in the closed state, the arc-shaped sealing section 302 completely covers the through hole 202. In application, the radius of curvature is adapted to the inner diameter of the release cylinder 2 to ensure that the arc-shaped sealing section 302 can fit tightly against the outer wall of the release cylinder 2. When the counterweight cylinder 3 is in the low position (closed state), the arc-shaped sealing section 302 can completely cover and seal the through hole 202, effectively preventing the discharge of condensate and the entry of external air (or vacuum leakage), ensuring the sealing performance of the system, which is especially important when the vacuum dehumidifier needs to maintain the vacuum level.

[0031] Reference Figure 2 The float body 5 is a hollow sealed structure. The density of the float body 5 is less than that of condensed water. In application, the hollow sealed structure ensures the buoyancy stability and pressure resistance of the float body 5 (it is not easily deformed in a vacuum environment). At the same time, the density is less than that of condensed water, which allows the float body 5 to float with the rise of water level and ensures that it can respond sensitively and reliably to changes in water level, thereby accurately driving the counterweight cylinder 3 to move.

[0032] Reference Figures 1-4The release cylinder 2, counterweight cylinder 3, and connecting rod 4 are made of stainless steel, and their surfaces are all coated with polytetrafluoroethylene (PTFE). In application, stainless steel provides excellent corrosion resistance, resisting the corrosion of condensate (which may contain tobacco extracts), thus extending the service life of the device. The PTFE coating has an extremely low coefficient of friction and excellent self-lubricating, non-stick, and chemical resistance, significantly reducing the sliding friction between the counterweight cylinder 3 and the release cylinder 2, making the operation smoother and more sensitive. It also prevents impurities or sediments in the condensate from adhering to the sliding parts or sealing surfaces, reducing the risk of jamming, lowering maintenance requirements, and further enhancing corrosion resistance.

[0033] The working principle of this utility model is as follows: When the water level is low, the water level of the condensate in the collection box 1 is lower than the trigger height of the float 5. The counterweight cylinder 3 slides down to the bottom of the release cylinder 2 due to its own weight. At this time, the arc-shaped sealing section 302 completely covers the through hole 202, preventing the condensate drain outlet 102 from releasing condensate, while maintaining the vacuum seal of the system.

[0034] When the water level is rising, the high-temperature condensate generated by the vacuum rehumidifier enters the collection box 1 through the condensate inlet 101. As the water level gradually rises, the float 5 floats up with the water level and drives the counterweight cylinder 3 to move upward along the guide groove 201 through the connecting rod 4. The slider 301 moves linearly in the guide groove 201 to avoid deflection.

[0035] When the water level is high, the water level reaches the set height (if the height of the collection box 1 is 80%), the counterweight cylinder 3 moves up until the through hole 202 is fully exposed, and the condensate flows into the condensate drain outlet 102 through the through hole 202 on the release cylinder 2 to achieve automatic discharge. At this time, the arc-shaped sealing section 302 is separated from the through hole 202 area and has no sealing effect.

[0036] As the condensate is discharged, the water level in the collection tank 1 drops, and the float 5 moves the counterweight cylinder 3 downward. When the water level drops below the critical point, the arc-shaped sealing section 302 of the counterweight cylinder 3 covers the through hole 202 again, closing the drainage channel and restoring the system to a sealed state.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
