Description

Technical Field

[0001] The present invention relates to the technical field of steam cooling, in particular to a steam cooling water saving device, and in particular to a steam cooling water saving device for a high-temperature pressure steam sterilizer. Background Art

[0002] High-temperature pressure steam sterilizers use saturated steam as their working medium, effectively sterilizing items in a short period of time. These sterilizers include pulsed vacuum pressure steam sterilizers and standard high-pressure steam sterilizers. They are widely used in domestic and international laboratories, hospital laboratories, food processing companies, pharmaceutical factories, and hospital disinfection supply centers. They sterilize instruments, culture media, and medical waste with excellent results, simple operation, and safety and reliability. They are ideal sterilization equipment for use in the medical, printing and dyeing, scientific research, food, and health centers sectors. During steam sterilization, the high-temperature steam discharged from the sterilization chamber must be cooled to room-temperature water to achieve both discharge and vacuum requirements.

[0003] Publication No. CN106918249A discloses a steam exhaust pipe cooling device for hospital pressure steam sterilizers. The device consists of a cold water inlet pipe, a temperature sensor, a steam inlet pipe, a steam sterilizer, a cooling water tank, a cooling coil, a water collection tank, and a water pump. Each steam sterilizer's exhaust pipe is equipped with a cooling coil, which is placed in a cooling water tank. The cooling coil outlet is connected to a steam water drain pipe. Steam from the steam sterilizer passes through the cooling coil, cools to 40°C to 50°C in the cooling water tank, and is then discharged through the steam water drain pipe. Although the above patent document avoids the problem of high-temperature steam easily flowing back and causing valves, pressure instruments, etc. of indoor high-pressure containers to be easily corroded and damaged, and the discharged hot water and high-temperature steam are also likely to cause deformation and bursting of outdoor water pipes, the above patent document places the cooling coil in the cooling water tank, and then passes the high-temperature steam through the cooling coil to cool the high-temperature steam. However, when the high-temperature steam is transported in the pipeline, the contact area between it and the cooling water in the cooling water tank is small, and the cooling effect is not ideal. Even if part of the high-temperature steam is cooled, the water formed after the high-temperature steam is cooled will be transported outward in the cooling coil, which can easily block the circulation of steam. In addition, although the traditional high-temperature steam sterilizer has a large contact area with the high-temperature steam and an ideal cooling effect, during the cooling process, the cooling water is turned on according to the highest steam flow rate, and during the steam discharge process in the sterilization chamber, the steam flow rate is gradually reduced. If the cooling water is still introduced at the highest temperature and flow rate, it will cause a waste of water resources. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a steam cooling water saving device for a high-temperature pressure steam sterilizer, comprising a high-temperature steam pipe and a cooling water pipe, wherein the high-temperature steam pipe and the cooling water pipe are arranged in parallel, and the axes of the high-temperature steam pipe and the cooling water pipe are on the same horizontal plane, two support rods are fixed in the high-temperature steam pipe, and a rectangular rod is connected between the two support rods, and a wedge-shaped movable plate is slidably sleeved on the rectangular rod. When there is a lot of steam in the high-temperature pressure steam sterilizer, the steam flow rate is large, and the high-temperature steam blows the wedge-shaped movable plate to move a long distance, so that the wedge-shaped movable plate squeezes the connecting rod and drives the connecting rod to move a long distance, thereby increasing the gap between the rubber shut-off valve and the cooling water pipe, so that the flow rate of the cooling water is increased. Conversely, when there is less high-temperature steam and the flow rate is small, the flow rate of the cooling water is reduced. That is, the present invention can automatically adjust the cooling water flow rate to avoid the waste of cooling water.

[0005] The present invention solves the technical problem and adopts the following technical solutions:

[0006] A steam cooling water saving device for a high-temperature pressure steam sterilizer comprises a high-temperature steam pipe and a cooling water pipe. A steam outlet pipe is fixed to and connected to the high-temperature pressure steam sterilizer, and the steam outlet pipe is connected to the high-temperature steam pipe.

[0008] The two support rods are arranged in the high-temperature steam pipe along the diameter direction of the inner hole of the high-temperature steam pipe and are perpendicular to the axis of the high-temperature steam pipe. The cross-sectional area of ​​the support rods is smaller than the cross-sectional area of ​​the inner hole of the high-temperature steam pipe.

[0009] Preferably, the wedge-shaped movable plate has a large head end and a small head end, and the wedge-shaped movable plate is a cone or a square cone;

[0010] A cooling box is connected at one end of the high-temperature steam pipe and the cooling water pipe away from the high-temperature pressure steam sterilizer, and an atomizing nozzle is installed at the end of the cooling water pipe extending into the cooling box. The cooling water is transported to the cooling box through the cooling water pipe to cool the high-temperature steam transported by the high-temperature steam pipe. A water pipe is fixed and connected at the bottom of the cooling box to transport the treated water to a designated location.

[0011] The steam cooling water saving device for a high-temperature pressure steam sterilizer includes a control mechanism for controlling the deformation of the rubber shutoff valve, comprising a connecting rod, a lug plate and a pulley provided at the top end of the connecting rod, and a sliding groove provided on the underside of the wedge-shaped movable plate, the pulley being adapted to fit within the sliding groove.

[0012] A conical cylinder is provided between the large end of the wedge-shaped movable plate and the adjacent support rod. The conical cylinder also has a large end and a small end. The small end of the conical cylinder is close to the large end of the wedge-shaped movable plate, and the small end of the conical cylinder can fit with the large end of the wedge-shaped movable plate. When the small end of the conical cylinder fits with the large end of the wedge-shaped movable plate, the large end of the wedge-shaped movable plate can seal the pipe opening of the small end of the conical cylinder.

[0013] An annular sleeve is fixed on the large end of the conical cylinder, and the outer side of the annular sleeve is fixed to the inner wall of the high-temperature steam pipe.

[0014] More preferably, a first circular hole is opened on the pipe wall of the high-temperature steam pipe, and a steam pipe sealing ring is glued into the first circular hole, a second circular hole is opened on the pipe wall of the cooling water pipe, and a cooling water pipe sealing ring is glued into the second circular hole, the connecting rod is sealingly slidably connected in the steam pipe sealing ring and the cooling water pipe sealing ring, and the two ends of the connecting rod are respectively located in the high-temperature steam pipe and the cooling water pipe, and the end of the connecting rod located inside the cooling water pipe is connected to the rubber shut-off valve, and the side of the rubber shut-off valve away from the connecting rod is fixedly connected to the inner wall of the cooling water pipe.

[0015] Furthermore, the end area of ​​the large end of the wedge-shaped moving plate is smaller than the cross-sectional area of ​​the inner cavity of the high-temperature steam pipe and larger than the cross-sectional area of ​​the hole cavity of the small end of the conical cylinder; when the wedge-shaped moving plate adopts a cone, the diameter of the large end of the wedge-shaped moving plate is smaller than the aperture of the inner cavity of the high-temperature steam pipe and larger than the aperture of the small end of the conical cylinder; when the wedge-shaped moving plate adopts a square cone, the side length of the large end of the wedge-shaped moving plate is smaller than the aperture of the inner cavity of the high-temperature steam pipe and larger than the aperture of the small end of the conical cylinder.

[0016] Furthermore, a baffle is fixed to the outer periphery of the connecting rod, and a second elastic member is also sleeved on the outer periphery of the connecting rod, one end of the second elastic member abuts against one side of the baffle, and the other end of the second elastic member abuts against the outer wall of the cooling water pipe;

[0017] Under normal conditions, the second elastic member has the potential energy to push the baffle and the connecting rod toward the high-temperature steam pipe, so that the end of the rubber shut-off valve connected to the connecting rod fits against the inner wall of the cooling water pipe, so that the rubber shut-off valve seals the pipe hole of the cooling water pipe and blocks the flow of cooling water.

[0018] The steam cooling water saving device for a high-temperature pressure steam sterilizer is provided with a first elastic member between the small end of the wedge-shaped movable plate and the adjacent support rod, one end of the first elastic member abuts against the support rod, and the other end of the first elastic member abuts against the small end of the wedge-shaped movable plate;

[0019] The limiting mechanism for limiting the moving path of the wedge-shaped movable plate includes a rectangular groove opened in the wedge-shaped movable plate. The shape and size of the cross-section of the rectangular groove are adapted to the shape and size of the cross-section of the rectangular rod. The wedge-shaped movable plate slides with the rectangular rod through the rectangular groove, and a sealing gasket is also provided in the rectangular groove.

[0020] Furthermore, limit plates are fixed on both sides of the rectangular groove, and limit grooves corresponding to the limit plates are opened on both sides of the rectangular rod, and the two limit plates are respectively slidably fitted in the corresponding limit grooves;

[0021] A first supporting plate is fixed at the bottom of the high-temperature steam pipe, a second supporting plate is fixed at the bottom of the cooling water pipe, and a fixing seat is fixed at the bottoms of the first supporting plate and the second supporting plate.

[0022] Furthermore, two ear plates are fixed to one end of the connecting rod located inside the high-temperature steam pipe, and a pulley is rotatably connected between the two ear plates. The pulley slides in the sliding groove, and both sides of the pulley are in contact with the inner wall of the sliding groove, so that the pulley can slide left and right in the sliding groove.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1: When high-temperature steam blows the wedge-shaped movable plate, it can cause the wedge-shaped movable plate to squeeze the connecting rod and drive the connecting rod to move. When the connecting rod moves, it drives the rubber shut-off valve to move, adjusting the gap between the rubber shut-off valve and the cooling water pipe. Cooling water can pass through the gap between the rubber shut-off valve and the cooling water pipe and be transported. When there is a lot of steam in the high-temperature pressure steam sterilizer, the steam flow rate is high, and the high-temperature steam blows the wedge-shaped movable plate to move a long distance, causing the wedge-shaped movable plate to squeeze the connecting rod and drive the connecting rod to move a long distance. That is, the gap between the rubber shut-off valve and the cooling water pipe is increased, which increases the flow rate of the cooling water. Conversely, when there is less high-temperature steam, the flow rate is low, that is, the flow rate of the cooling water is reduced. The present invention can automatically adjust the cooling water flow rate to avoid wasting cooling water.

[0025] 2: Through the setting of the conical cylinder, and with the first elastic member in the normal state, the side of the wedge-shaped movable plate away from the first elastic member is in contact with the side of the conical cylinder, so that when high-temperature steam blows toward the wedge-shaped movable plate through the conical cylinder, it can blow the wedge-shaped movable plate to move. Since the wedge-shaped movable plate and the conical cylinder are in contact, the wedge-shaped movable plate will also be blown to move when there is less steam, and the wedge-shaped movable plate will be driven to move a relatively short distance.

[0026] 3: Due to the setting of the pulley and the sliding groove, and the two sides of the pulley fit together with the inner walls of the two sides of the sliding groove, the pulley can move stably in the sliding groove, and the friction is reduced when the pulley rolls in the sliding groove, which delays the life of the equipment.

[0041] A steam cooling water saving device for a high-temperature pressure steam sterilizer comprises a high-temperature steam pipe 1 and a cooling water pipe 2. The high-temperature steam pipe 1 and the cooling water pipe 2 are arranged in parallel, and the axes of the high-temperature steam pipe 1 and the cooling water pipe 2 are on the same horizontal plane. It should be noted that during use, the high-temperature steam pipe 1 is fixed to the high-temperature pressure steam sterilizer, and the high-temperature pressure steam sterilizer is respectively fixed and connected with a steam outlet pipe, and the steam outlet pipe is fixed and connected to the high-temperature steam pipe 1, and a solenoid valve is installed on the steam outlet pipe. Figure 1 and Figure 2 As shown, the steam outlet pipe of the high-temperature pressure steam sterilizer is connected to the right end of the high-temperature steam pipeline 1, and the high-temperature steam discharged from the high-temperature pressure steam sterilizer enters the high-temperature steam pipeline 1 from the right end of the high-temperature steam pipeline 1 through the steam outlet pipe.

[0042] There are two support rods 3 fixed in the high-temperature steam pipe 1. Figure 2 and Figure 3 As shown, the two support rods 3 are arranged in the high-temperature steam pipe 1 along the diameter direction of the inner hole of the high-temperature steam pipe 1 and are perpendicular to the axis of the high-temperature steam pipe 1. The cross-sectional area of ​​the support rods 3 is smaller than the cross-sectional area of ​​the inner hole of the high-temperature steam pipe 1 to avoid blocking the flow of steam in the inner hole of the high-temperature steam pipe 1. In this embodiment, Figure 3 As shown, the cross-sectional area of ​​the support rod 3 is 1 / 5 to 1 / 10 of the cross-sectional area of ​​the inner hole of the high-temperature steam pipe 1 .

[0043] A rectangular rod 4 is fixedly connected between the two support rods 3, and a wedge-shaped moving plate 5 is slidably connected to the outer periphery of the rectangular rod 4. The wedge-shaped moving plate 5 has a large end and a small end. The cross-section of the wedge-shaped moving plate 5 along the axis of the high-temperature steam pipe 1 is trapezoidal, as shown in FIG. Figure 2 and Figure 5 As shown, the left side of the wedge-shaped movable plate 5 is the small head end, and the right side is the large head end.

[0044] The cross section of the wedge-shaped moving plate 5 along the direction perpendicular to the axis of the high-temperature steam pipe 1 is circular or square, that is, the wedge-shaped moving plate 5 is a cone or a square cone.

[0045] like Figure 2 and Figure 5 As shown, a rubber shut-off valve 9 that will deform under force is provided in the cooling water pipe 2, a control mechanism for controlling the deformation of the rubber shut-off valve 9 is provided between the high-temperature steam pipe 1 and the cooling water pipe 2, and a limiting mechanism for limiting the moving path of the wedge-shaped moving plate 5 is provided in the high-temperature steam pipe 1.

[0046] like Figure 7 and Figure 8 As shown, the control mechanism for controlling the deformation of the rubber shut-off valve 9 includes a connecting rod 8, an ear plate 14 and a pulley 15 provided at the top of the connecting rod 8, and a sliding groove 16 opened on the lower side of the wedge-shaped movable plate 5, and the pulley 15 is adapted to the sliding groove 16.

[0047] It should be noted that a cooling box is connected at one end of the high-temperature steam pipe 1 and the cooling water pipe 2 away from the high-temperature pressure steam sterilizer, and an atomizing nozzle is installed at one end of the cooling water pipe 2 extending into the cooling box. The cooling water is transported to the cooling box through the cooling water pipe 2 to cool the high-temperature steam transported by the high-temperature steam pipe 1. In addition, a water pipe is fixed and connected at the bottom of the cooling box to transport the treated water to a designated location.

[0048] Specifically, such as Figure 2 、 Figure 5 and Figure 6 As shown, a conical cylinder 7 is provided between the large end of the wedge-shaped movable plate 5 and the adjacent support rod 3. The conical cylinder 7 also has a large end and a small end. The small end of the conical cylinder 7 is close to the large end of the wedge-shaped movable plate 5, and the small end of the conical cylinder 7 can fit with the large end of the wedge-shaped movable plate 5. When the small end of the conical cylinder 7 fits with the large end of the wedge-shaped movable plate 5, the large end of the wedge-shaped movable plate 5 can seal the pipe opening of the small end of the conical cylinder 7. An annular sleeve 21 is fixed to the large end of the conical cylinder 7, and the outer side of the annular sleeve 21 is fixed to the inner wall of the high-temperature steam pipe 1, that is, the conical cylinder 7 is fixedly connected to the inner wall of the high-temperature steam pipe 1 through the annular sleeve 21.

[0049] A first circular hole is opened on the pipe wall of the high-temperature steam pipe 1, and a steam pipe sealing ring 10 is glued into the first circular hole. A second circular hole is opened on the pipe wall of the cooling water pipe 2, and a cooling water pipe sealing ring 11 is glued into the second circular hole. A connecting rod 8 is sealed and slid in the steam pipe sealing ring 10 and the cooling water pipe sealing ring 11, and the two ends of the connecting rod 8 are respectively located in the high-temperature steam pipe 1 and the cooling water pipe 2, and the end of the connecting rod 8 located inside the cooling water pipe 2 is connected to the rubber shut-off valve 9. If a gluing connection is adopted, the side of the rubber shut-off valve 9 away from the connecting rod 8 is fixed to the inner wall of the cooling water pipe 2, such as a gluing connection.

[0050] like Figure 2 and Figure 5 As shown, the end area of ​​the large end of the wedge-shaped movable plate 5 is smaller than the cross-sectional area of ​​the inner cavity of the high-temperature steam pipe 1, and larger than the cross-sectional area of ​​the cavity of the small end of the tapered cylinder 7. When the wedge-shaped movable plate 5 is a cone, the diameter of the large end of the wedge-shaped movable plate 5 is smaller than the aperture of the inner cavity of the high-temperature steam pipe 1, and larger than the aperture of the small end of the tapered cylinder 7. When the wedge-shaped movable plate 5 is a square cone, the side length of the large end of the wedge-shaped movable plate 5 is smaller than the aperture of the inner cavity of the high-temperature steam pipe 1, and larger than the aperture of the small end of the tapered cylinder 7.

[0051] like Figure 6 As shown, a baffle 12 is fixed on the outer periphery of the connecting rod 8, and a second elastic member 13 is also sleeved on the outer periphery of the connecting rod 8, one end of the second elastic member 13 abuts against one side of the baffle 12, and the other end of the second elastic member 13 abuts against the outer wall of the cooling water pipe 2.

[0052] like Figure 1 As shown, a first support plate 23 is fixed at the bottom of the high-temperature steam pipe 1 , a second support plate 24 is fixed at the bottom of the cooling water pipe 2 , and a fixing seat 22 is fixed to the bottoms of the first support plate 23 and the second support plate 24 .

[0053] It should be noted that the second elastic member 13 can be a device such as a spring or a rubber elastic tube, and under normal conditions, the second elastic member 13 has the potential energy to push the baffle 12 and the connecting rod 8 toward the high-temperature steam pipe 1, so that the end of the rubber shut-off valve 9 connected to the connecting rod 8 fits against the inner wall of the cooling water pipe 2, that is, the rubber shut-off valve 9 seals the pipe hole of the cooling water pipe 2, blocking the flow of cooling water.

[0054] Example 2

[0055] A steam cooling water saving device for a high-temperature pressure steam sterilizer, based on embodiment one, wherein a limiting mechanism for limiting the moving path of a wedge-shaped movable plate 5 includes a rectangular groove 20 opened in the wedge-shaped movable plate 5, and the shape and size of the cross-section of the rectangular groove 20 are adapted to the shape and size of the cross-section of the rectangular rod 4. The wedge-shaped movable plate 5 slides with the rectangular rod 4 through the rectangular groove 20. In order to enhance the sealing performance of the sliding fit between the rectangular groove 20 and the rectangular rod 4, a sealing gasket can also be provided in the rectangular groove 20. The sealing gasket can specifically be provided at the notches at both ends of the rectangular groove 20.

[0056] Furthermore, in order to enhance the smoothness of the sliding fit, a limit plate 18 may be fixed on both sides of the rectangular groove 20, such as Figure 9 As shown, limiting grooves 17 corresponding to the limiting plates 18 are provided on both sides of the rectangular rod 4 , and the two limiting plates 18 are slidably fitted in the corresponding limiting grooves 17 .

[0057] It should be noted that when the wedge-shaped movable plate 5 moves on the rectangular rod 4, when the wedge-shaped movable plate 5 moves to the farthest position away from the conical cylinder 7, the flow rate of the high-temperature steam is the largest, and when the wedge-shaped movable plate 5 moves, it drives the pulley 15 to roll to the other end of the sliding groove 16, and at this time the connecting rod 8 moves and squeezes the rubber shut-off valve 9, so that the rubber shut-off valve 9 is flattened, so that the rubber shut-off valve 9 no longer blocks the cooling water pipe 2, that is, the flow rate of the cooling water is the largest.

[0058] It should be noted that when the wedge-shaped movable plate 5 moves on the rectangular rod 4, due to the setting of the rectangular groove 20 and the rectangular rod 4, the wedge-shaped movable plate 5 can move stably on the rectangular rod 4, and due to the setting of the sealing gasket, the sealing between the rectangular groove 20 and the rectangular rod 4 is increased. When the high-temperature steam is blown toward the wedge-shaped movable plate 5 through the conical cylinder 7, the high-temperature steam is prevented from leaking through the gap between the rectangular groove 20 and the rectangular rod 4, so that the high-temperature steam can be blown toward the wedge-shaped movable plate 5 and blow the wedge-shaped movable plate 5 to move.

[0059] like Figure 2 and Figure 5 As shown, the wedge-shaped movable plate 5 is located between the two support rods 3, and a first elastic member 6 is provided between the small end of the wedge-shaped movable plate 5 and the adjacent support rod 3, one end of the first elastic member 6 abuts against the support rod 3, and the other end of the first elastic member 6 abuts against the small end of the wedge-shaped movable plate 5.

[0060] like Figures 6 to 8 As shown, two ear plates 14 are fixed to one end of the connecting rod 8 located inside the high-temperature steam pipe 1, and a pulley 15 is rotatably connected between the two ear plates 14. The pulley 15 slides in the sliding groove 16, and both sides of the pulley 15 are in contact with the inner wall of the sliding groove 16, so that the pulley 15 can slide left and right in the sliding groove 16.

[0061] It should be noted that the first elastic member 6 can be a device such as a spring or a rubber elastic tube, and under normal conditions, the first elastic member 6 has the potential energy to push the wedge-shaped movable plate 5 to move to the right, pushing the wedge-shaped movable plate 5 to fit with the small end of the conical cylinder 7, so that only when the high-temperature steam blows towards the wedge-shaped movable plate 5 through the conical cylinder 7 can the wedge-shaped movable plate 5 be blown to move away from the conical cylinder 7, so that the high-temperature steam can pass through the gap between the wedge-shaped movable plate 5 and the inner cavity of the high-temperature steam pipe 1.

[0062] Working principle: When high temperature steam is transported into the high temperature steam pipe 1, Figure 1 and Figure 2 As shown, the conveying direction of high-temperature steam in the high-temperature steam pipe 1 is from right to left. When the high-temperature steam passes through the inner cavity of the conical cylinder 7, the conical cylinder 7 can increase the air pressure of the high-temperature steam and blow it toward the wedge-shaped movable plate 5, thereby blowing the wedge-shaped movable plate 5 to overcome the elastic force of the first elastic member 6 and move to the left. When the wedge-shaped movable plate 5 moves on the rectangular rod 4, the pulley 15 can move in the sliding groove 16. When the wedge-shaped movable plate 5 moves, the wedge-shaped movable plate 5 squeezes the connecting rod 8, thereby driving the connecting rod 8 to overcome the elastic force of the second elastic member 13 and move toward the cooling water pipe 2. When the connecting rod 8 moves toward the cooling water pipe 2, it pushes the rubber shut-off valve 9 to deform inward, so that the rubber shut-off valve 9 no longer completely seals the cooling water pipe 2, and a gap appears between the rubber shut-off valve 9 and the inner hole of the cooling water pipe 2, and the cooling water can pass through the rubber shut-off valve The gap between the valve 9 and the cooling water pipe 2 is transported. When there is a lot of steam in the high-temperature pressure steam sterilizer, the flow rate of the steam through the high-temperature steam pipe 1 is large, and the flow rate of the high-temperature steam through the conical cylinder 7 is fast, so that the high-temperature steam blows the wedge-shaped movable plate 5 to move a farther distance, so that the wedge-shaped movable plate 5 squeezes the connecting rod 8 and drives the connecting rod 8 to move a farther distance toward the cooling water pipe 2, thereby making the gap between the rubber shut-off valve 9 and the cooling water pipe 2 larger, that is, the flow rate of cooling water increases. Similarly, it can be seen that when there is little high-temperature steam in the high-temperature pressure steam sterilizer, the flow rate is small, that is, the distance the wedge-shaped movable plate 5 moves to the left is short, so that the wedge-shaped movable plate 5 squeezes the connecting rod 8 and drives the connecting rod 8 to move a shorter distance toward the cooling water pipe 2, thereby reducing the gap between the rubber shut-off valve 9 and the cooling water pipe 2, that is, the flow rate of cooling water decreases.
