Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling structures, and in particular to a steam cooling structure for a sterilizer. Background Technology
[0002] In the fields of medical sterilization, biopharmaceuticals, and food processing, steam sterilizers are core equipment for ensuring a sterile environment, and their reliability is directly related to product safety and production compliance. Among them, the steam cooling structure (including heat exchange box and heat exchange coil) plays a crucial role in rapidly condensing high-temperature steam, recovering latent heat, and maintaining system pressure balance.
[0003] However, traditional sterilizers generally adopt a fixed heat exchange coil design, that is, the heat exchange coil is permanently fixed to the inner cavity of the heat exchange box by welding or rigid clamps. The inner cavity of the heat exchange box is usually designed as a compact flow channel to meet the requirements of high-efficiency heat transfer. After long-term operation, protein residues, inorganic salt crystals, and microbial films accumulate on the surface of the coil, forming a dirt layer. During manual cleaning, due to the limited space, the operator must adopt an unconventional posture (sideways probing) to enter the inner cavity of the heat exchange box and use a high-pressure water gun for rinsing. Due to the limited space, the above-mentioned coil cleaning operation is time-consuming.
[0004] Therefore, how to achieve rapid cleaning and maintenance of heat exchange coils has become an urgent technical problem to be solved. Utility Model Content
[0005] The purpose of this invention is to provide a steam cooling structure for a sterilizer to solve the problems mentioned in the background art.

[0010] Preferably, a water outlet valve is provided on the other side of the heat exchange box, which is used to control the flow of cooling water out of the heat exchange box.
[0011] Preferably, the heat exchange coil is provided with multiple turbulence strips on the side near the water inlet valve.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: This utility model provides the following... Figure 1 - Figure 4 The sterilizer steam cooling structure shown includes: a heat exchange box 1, a heat exchange assembly, and a positioning assembly; Specifically, the heat exchange assembly is used for cooling the flow of high-temperature steam. The heat exchange assembly includes a heat exchange coil 2, and sliding parts are symmetrically arranged on the sides of the heat exchange coil 2. The inner wall of the heat exchange box 1 is provided with a guide part for limiting the sliding parts. It should be noted that the heat exchange coil 2 is made of copper alloy. The steam from the sterilizer can be introduced into the heat exchange coil 2 through a stainless steel metal bend. The positioning component is used to lock the position of the heat exchange coil 2. The positioning component is inserted and connected to the side of the heat exchange box 1. The heat exchange box 1 is used for the circulation of cooling water. Furthermore, the sliding part includes: a sliding bracket 3 and a locking hole 301; It should be noted that multiple sliding frames 3 are symmetrically arranged on both sides of the heat exchange coil 2. The sides of the sliding frames 3 are inserted and connected to the inner wall of the heat exchange box 1. The locking hole 301 is opened on the side of one of the sliding frames 3. The locking hole 301 is used to position the insertion of the component. Specifically, the sliding frame 3 and the heat exchange coil 2 are fixed by welding, and the guide part includes: sliding groove 4 and flat groove 10; It should be noted that the sliding groove 4 is provided with the inner wall of the heat exchange box 1. The sliding groove 4 is used for the insertion of the sliding frame 3. The flat groove 10 is provided with the inner wall of the sliding groove 4. The flat groove 10 is used for the flattening of the heat exchange coil 2. The sliding frame 3 is L-shaped, and the bottom protrusion of the sliding frame 3 is inserted and connected to the inner wall of the heat exchange box 1. Specifically, the sliding groove 4 and the flat groove 10 form a T-shape. After the protrusion on the side of the heat exchange coil 2 enters the flat groove 10 from the sliding groove 4, the side of the heat exchange coil 2 away from the bottom protrusion of the sliding frame 3 is attached to the top of the heat exchange box 1, so that the heat exchange coil 2 can be unfolded and fixed on the top of the heat exchange box 1. It should be noted that a water inlet valve 101 is provided on one side of the heat exchange box 1. The water inlet valve 101 is used to control the flow of cooling water into the heat exchange box 1. A water outlet valve 102 is provided on the other side of the heat exchange box 1. The water outlet valve 102 is used to control the flow of cooling water out of the heat exchange box 1. Multiple turbulence strips 201 are provided on the side of the heat exchange coil 2 near the inlet valve 101; Specifically, the turbulent flow strip 201 is fixed to the heat exchange coil 2 by welding. The turbulent flow strip 201 forces the fluid to generate local swirling and strong turbulence, breaking the laminar flow layer that hinders heat transfer and reducing the temperature gradient between the center of the flow channel and the wall of the heat exchange box 1.
[0021] Example 2: A positioning component applied to the sterilizer steam cooling structure in Example 1; Specifically, the positioning components include: a rod 5, a compression spring 6, a pressure ring 8, a closing ring 9, and a pull ring 7; It should be noted that one end of the insertion rod 5 is inserted and connected to the side of the heat exchange box 1 and the inner cavity of the locking hole 301. The compression spring 6 is sleeved on the outside of the insertion rod 5.

The closing ring 9 is sleeved on the outside of the insertion rod 5 and is located on the side of the compression spring 6 away from the sliding frame 3. The side of the closing ring 9 is fixedly connected to the side of the heat exchange box 1. The pull ring 7 is set at the other end of the insertion rod 5. Specifically, the pull ring 7 is used to assist in pulling the insertion rod 5, the pressure ring 8 is welded to the insertion rod 5, and the sealing ring 9 is welded to the side of the heat exchange box 1. By inserting the insertion rod 5 into the locking hole 301, the position of the heat exchange coil 2 is locked to prevent the position from shifting when the cooling water impacts. During the movement of the sliding frame 3, the insertion rod 5 disengages from the locking hole 301.
[0022] In practical use, a sliding part is provided at the intersection of the heat exchange box 1 and the heat exchange coil 2. The sliding part is used in conjunction with the guide part on the inner wall of the heat exchange box 1, so that the heat exchange coil 2 can be pulled out and unfolded by the combination of the guide part and the sliding part. Compared with the fixed heat exchange coil 2, this design can pull out and unfold the heat exchange coil 2 to the top of the heat exchange box 1 for washing and cleaning of the scale on the surface of the heat exchange coil 2, avoiding the problem of time-consuming manual cleaning due to the narrow inner cavity of the heat exchange box 1.
