Description
Technical Field
[0001] This utility model belongs to the field of condensate recovery technology for steam sterilization chambers, specifically relating to a condensate recovery device for steam sterilization chambers. Background Technology
[0002] In the field of kernel processing (such as peanuts, walnuts, almonds, etc.), steam sterilization is the core process to ensure product hygiene and safety. In low-temperature steam sterilization equipment, condensate is a product formed by the liquefaction of steam after it comes into contact with cold kernels and the box wall. The condensate is pure soft water and can be directly reused in the steam generator after being recovered. If the condensate is not recovered, it will accumulate at the bottom of the box or in the gap between the trays, which will cause the kernels at the bottom to be soaked in water. Traditional steam sterilization chambers rely on static channels to collect condensate, which has problems such as long drainage paths and large residual amounts. In addition, the chamber's sealing structure cannot be dynamically adjusted with changes in water level, leading to steam leakage or condensate backflow, and in severe cases, frequent shutdowns for drainage are required. Utility Model Content
[0003] In view of this, the present invention provides a condensate recovery device for a steam sterilization chamber. Through a dynamic collection structure that links the V-shaped groove and the scraper, the condensate recovery efficiency can be significantly improved. The fluid optimization design of the recovery tank reduces flow resistance and accelerates drainage speed. The float design ensures that the condensate is discharged quickly when it reaches the critical water level, and completely blocks the steam leakage path through dynamic sealing. It takes into account both drainage efficiency and chamber airtightness, and ultimately achieves multiple goals such as efficient condensate recovery, reduced steam energy consumption and improved stability of sterilization process.
[0004] To address the aforementioned technical problems, this utility model provides a condensate recovery device for a steam sterilization chamber, comprising a steam sterilization chamber body and a recovery mechanism disposed at its bottom. A perforated plate is located at the bottom of the inner cavity of the steam sterilization chamber body directly above the recovery mechanism. The recovery mechanism includes a V-shaped groove disposed at the bottom of the steam sterilization chamber body, with a recovery trough at the bottom angle of the V-shaped groove. Fixed rods are provided on both sides of the bottom of the inner cavity of the steam sterilization chamber body, and a sliding mounting plate is slidably connected between the two fixed rods. Scrapers are provided at both ends of the lower side of the sliding mounting plate, and the scrapers contact the inclined surfaces on both sides of the V-shaped groove. A collection component is also provided at the bottom of the steam sterilization chamber body. This dynamic collection structure, linking the V-shaped groove and the scrapers, significantly improves condensate recovery efficiency. The fluid optimization design of the recovery trough reduces flow resistance and accelerates drainage. The design of the collection component ensures rapid discharge of condensate when it reaches the critical water level and completely blocks steam leakage paths through dynamic sealing, balancing drainage efficiency and chamber airtightness. Ultimately, this achieves multiple objectives: efficient condensate recovery, reduced steam energy consumption, and improved stability of the sterilization process.
[0005] The cross-section of the recovery tank is arc-shaped, and both ends of the recovery tank are inclined towards the center, which accelerates the kinetic energy of the water flow.
[0006] The recovery mechanism also includes a drive screw that is rotatably connected to the bottom of the inner cavity of the steam sterilization chamber. The drive screw is threadedly connected to the threaded hole on the sliding mounting plate, thus providing a driving source for the mounting plate.
[0007] The recycling mechanism also includes a motor located at one end of the steam sterilization chamber. The output shaft of the motor is fixedly connected to one end of the drive screw, which provides a drive source for the screw.
[0008] The collection component includes a guide pipe located at the center of the bottom of the steam sterilization chamber, which is connected to the recovery tank. A drain hole is provided at the bottom axis of the guide pipe. A water collection tank is located at the center of the bottom of the steam sterilization chamber, and the guide pipe is located inside the water collection tank. The water collection tank is connected to the drain hole. A water outlet is located at the bottom axis of the water collection tank and is connected to the water collection tank, thus playing a preliminary role in collecting condensate.
[0009] The collection assembly also includes a float placed above the drain hole. The lower end of the float is provided with a guide rod, which is located inside the drain hole. The upper end of the drain hole is provided with an annular groove that matches the float, thus preventing steam leakage.
[0010] The collection assembly also includes a spring disposed between the bottom wall of the guide rod and the lower end face of the guide tube. The spring is externally sleeved with the guide rod to provide elastic restoring force for the float.
[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: During the steam sterilization of kernels, the condensate generated inside the steam sterilization chamber naturally seeps down through the perforated plate at the bottom of the chamber into the V-shaped groove. At this time, the drive mounting plate slides back and forth along the fixed rod, causing the scraper to adhere tightly to the inclined surfaces on both sides of the V-shaped groove, continuously scraping the condensate towards the bottom recovery tank. The arc-shaped cross-section of the recovery tank and the design of its two ends tilting downwards towards the center accelerate the flow of water, which eventually enters the collection component. Through the dynamic collection structure that links the V-shaped groove and the scraper, the condensate recovery efficiency is significantly improved. The fluid optimization design of the recovery tank reduces flow resistance and accelerates drainage. The design of the collection component ensures that the condensate is quickly discharged when it reaches the critical water level, and completely blocks the steam leakage path through dynamic sealing, balancing drainage efficiency and chamber airtightness. Ultimately, this achieves multiple goals: efficient condensate recovery, reduced steam energy consumption, and improved stability of the sterilization process.
[0012] The motor drives the lead screw to rotate back and forth, causing the sliding mounting plate to slide back and forth along the fixed rod, so that the scraper is in close contact with the inclined surfaces on both sides of the V-shaped groove, continuously scraping the condensate water towards the bottom recovery tank, thus achieving a rapid driving effect.
[0013] When the water level in the guide pipe rises, the float rises with the liquid surface. The float overcomes the spring force and separates from the drain hole. At this time, the condensate flows into the water collection tank. When the water level drops, the float returns to its original position under the spring's restoring action, quickly sealing the drain hole and preventing steam from leaking out.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0017] This embodiment provides a condensate recovery device for a steam sterilization chamber, such as... Figure 1-4As shown: The steam sterilization chamber 100 includes a steam sterilization chamber body 100 and a recovery mechanism located at its bottom. A perforated plate is located at the bottom of the inner cavity of the steam sterilization chamber body 100, directly above the recovery mechanism. The perforated plate provides support for the kernel placement rack and allows condensate to pass through. The recovery mechanism includes a V-shaped groove at the bottom of the steam sterilization chamber body 100, used to quickly guide the cooled water to its angle. A recovery trough 200 is located at the bottom angle of the V-shaped groove for quickly draining the condensate from the angle of the V-shaped groove. The steam sterilization chamber 100 has fixed rods 201 on both sides of the bottom of the inner cavity. A sliding mounting plate 202 is slidably connected between the two fixed rods 201. Scrapers 203 are provided at both ends of the lower side of the sliding mounting plate 202. The scrapers 203 are in contact with the inclined surfaces on both sides of the V-shaped groove. The bottom of the scraper 203 matches the corresponding inclined surface of the V-shaped groove. The bottom of the steam sterilization chamber 100 is also provided with a collection component. The cross-section of the recovery tank 200 is arc-shaped, and the two ends of the recovery tank 200 are inclined towards its center.
[0018] During the steam sterilization of kernels, the condensate generated inside the steam sterilization chamber 100 naturally seeps down through the perforated plate at the bottom of the chamber's inner cavity into the V-shaped groove. At this time, the drive mounting plate 202 slides back and forth along the fixed rod 201, causing the scraper 203 to adhere tightly to the inclined surfaces on both sides of the V-shaped groove, continuously scraping the condensate towards the bottom recovery tank 200. The arc-shaped cross-section of the recovery tank 200 and the design of its two ends tilting downwards towards the center accelerate the flow energy of the water, which eventually enters the collection component. Through the dynamic collection structure that links the V-shaped groove and the scraper 203, the condensate recovery efficiency is significantly improved. The fluid optimization design of the recovery tank 200 reduces flow resistance and accelerates drainage. The design of the collection component ensures that the condensate is quickly discharged when it reaches the critical water level, and completely blocks the steam leakage path through dynamic sealing, balancing drainage efficiency and chamber airtightness. Ultimately, this achieves multiple goals: efficient condensate recovery, reduced steam energy consumption, and improved stability of the sterilization process.
[0019] like Figure 2-4 As shown, the recovery mechanism also includes a drive screw 204 rotatably connected to the bottom of the inner cavity of the steam sterilization chamber 100. The drive screw 204 is threadedly connected to the threaded hole provided on the sliding mounting plate 202. The recovery mechanism also includes a motor 205 provided at one end of the steam sterilization chamber 100. The output shaft of the motor 205 is fixedly connected to one end of the drive screw 204 to provide a drive source for the screw 204.
[0020] The motor 205 drives the lead screw 204 to rotate back and forth, causing the sliding mounting plate 202 to slide back and forth along the fixed rod 201, so that the scraper 203 is in close contact with the inclined surfaces on both sides of the V-shaped groove, continuously scraping the condensate water towards the bottom recovery tank 200, thus achieving a rapid driving effect.
[0021] like Figure 2-4As shown, the collection assembly includes a guide pipe 300 located at the center of the bottom of the steam sterilization chamber 100. The bottom of the inner cavity of the guide pipe 300 is tapered to facilitate the discharge of condensate. The guide pipe 300 is connected to the recovery tank 200 to ensure that condensate smoothly enters the guide pipe 300. A drain hole 301 is provided at the bottom axis of the guide pipe 300. A water collection tank 302 is located at the center of the bottom of the steam sterilization chamber 100 to facilitate the initial collection of condensate. The guide pipe 300 is located inside the water collection tank 302, which is connected to the drain hole 301. A water outlet 303 is provided in the outlet located at the bottom axis of the water collection tank 302. The water outlet 303 is used to connect with the external... The pump body is connected so that the condensate can be directly reused in the steam generator for secondary use. The outlet pipe 303 is connected to the water collection tank 302. The collection assembly also includes a float 304 placed on the upper end of the drain hole 301. The lower end of the float 304 is provided with a guide rod 305. The cross-section of the guide rod 305 is an inverted T-shaped structure. The guide rod 305 is located in the drain hole 301. The upper end of the drain hole 301 is provided with an annular groove that matches the float 304 to improve the sealing effect between the float 304 and the drain hole 301. The collection assembly also includes a spring 306 set between the bottom wall surface of the guide rod 305 and the lower end surface of the guide pipe 300. The spring 306 is movably sleeved on the outside of the guide rod 305.
[0022] When the water level in the guide pipe 300 rises, the float 304 floats with the liquid surface. The float 304 overcomes the elastic force of the spring 306 and separates from the drain hole 301. At this time, the condensate flows into the water collection tank 302. When the water level drops, the float 304 resets under the restoring action of the spring 306, quickly sealing the drain hole 301 to prevent steam from leaking out.
[0023] The working principle of the condensate recovery device for a steam sterilization chamber provided by this utility model is as follows: During the steam sterilization of kernels, the condensate generated inside the steam sterilization chamber 100 naturally seeps down through the perforated plate at the bottom of the chamber cavity into the V-shaped groove. At this time, the motor 205 drives the lead screw 204 to rotate back and forth, causing the sliding mounting plate 202 to slide back and forth along the fixed rod 201, so that the scraper 203 is in close contact with the inclined surfaces on both sides of the V-shaped groove, continuously scraping the condensate towards the bottom recovery tank 200. The arc-shaped cross-section of the recovery tank 200 and the design of the two ends tilting downwards towards the center accelerate the flow energy of the water, and finally enter the guide pipe 300. When the water level in the guide pipe 300 rises, the float 304 rises with the liquid surface, and the float 304 overcomes the spring 3 When the elastic ball 306 separates from the drain hole 301, the condensate flows into the collection tank 302. When the water level drops, the float 304 resets under the action of the spring 306, quickly sealing the drain hole 301 to prevent steam from leaking back. The dynamic collection structure linked by the V-groove and scraper 203 significantly improves the condensate recovery efficiency. The fluid optimization design of the recovery tank 200 reduces flow resistance and accelerates drainage. The design of the float 304 ensures that the condensate is discharged quickly when the critical water level is reached, and completely blocks the steam leakage path through dynamic sealing, balancing drainage efficiency and cabin airtightness. Ultimately, it achieves multiple goals of efficient condensate recovery, reduced steam energy consumption, and improved stability of the sterilization process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
