[0001] This application is a divisional application of the application filed on September 19, 2024, with application number 202411305090.5 and invention name “A buffer device in a sterilization cabinet”. Technical Field

[0002] The invention relates to the technical field of steam buffer devices, and in particular to a buffer device used in a sterilizing cabinet. Background Art

[0003] There are many methods used for sterilization, such as chemical reagent sterilization, radiation sterilization, dry heat sterilization, moist heat sterilization and filtration sterilization. Among them, high-pressure steam sterilization technology is widely used in the food processing field. The principle of high-pressure steam sterilization is to use saturated pressure steam to quickly and reliably disinfect and sterilize items. High-pressure steam sterilization generally requires the assistance of a special sterilization cabinet. When in use, the steam delivered generally has a certain pressure, which may cause impact on the material to be sterilized, and it is necessary to configure a buffer device for the steam.

[0004] In order to ensure that the steam is evenly distributed upward without obstacles and contacts the materials for sterilization, the steam outlet and groove of the container for buffering the steam on the steam buffer device are generally arranged at the top of the container. In order to prevent the fallen materials or debris from entering the container or clogging the steam outlet and groove during loading and unloading, some steam outlets and grooves are equipped with switch components. However, the switch components on the existing buffer devices often require additional manual switching before and after loading and unloading or before and after steam input, which is troublesome and inconvenient to operate. Summary of the invention

[0005] In view of this, the present invention provides a buffer device for a sterilization cabinet to solve the problem that the switch components on the steam outlet and the groove need additional manual switching before and after loading and unloading or before and after steam input, which is troublesome and inconvenient to operate.

[0006] The technical solution proposed by the present invention is: a buffer device for a sterilizing cabinet, specifically comprising a steam buffer cylinder; the steam buffer cylinder is installed on the bottom side of the sterilizing cabinet to spread high-temperature sterilizing steam upward;

[0008] A conical plugging cover is slidably installed inside the steam buffer cylinder. Under normal circumstances, the conical plugging cover abuts and blocks the air inlet at the right end of the steam buffer cylinder; at least one transverse positioning shaft is welded in the right side part of the steam buffer cylinder; at least two inclined curved rods are symmetrically rotatably connected at the front and rear sides of the conical plugging cover, and the tail end of each curved rod is rotatably connected to a shaft sleeve, and the two shaft sleeves are slidably matched with the transverse positioning shaft through spring pushing; a longitudinal sliding shaft supported to the left is welded at the center of the conical plugging cover, and the longitudinal sliding shaft is installed in the center with a limited position; a U-shaped force frame is welded and hoisted at the bottom of a row of the exhaust parts, and a horizontally longitudinally arranged push plate is welded at the bottom of the middle section of the longitudinal sliding shaft, and the front end part of the push plate is supported in an upward tilt; the inclined part of the push plate abuts and contacts with the bottom horizontal part of the force frame; when pressurized steam is input into the air inlet at the right end of the steam buffer cylinder, the conical plugging cover is pushed open.

[0011] The top end of the exhaust component is located on the left and right sides of the V-shaped groove and is an oblique structure. When the V-shaped groove is plugged into the lower conical structure of the blocking rod, the oblique parts on the left and right sides of the V-shaped groove are connected with the conical part on the upper side of the blocking rod to form two downward extending and enlarged inclined material guide surfaces.

[0012] Furthermore,

[0013] A rectangular support frame is sleeved and welded on the conical blocking cover, and the tail ends of the two bent rods are rotatably matched with the vertical support shaft rods on the front and rear sides of the rectangular support frame.

[0014] Furthermore,

[0015] A vertical support ear plate is welded on the bottom plate of the steam buffer cylinder at the middle position in the front-to-back direction, and the longitudinal sliding shaft penetrates and slides with the vertical support ear plate;

[0016] The air inlet pipe is connected with the air inlet port by screw locking.

[0017] Furthermore,

[0018] Two vertical positioning shafts are welded symmetrically in the middle position of the steam buffer cylinder in the left and right directions, and two rows of connecting short plates are symmetrically welded between the bottom parts of a row of exhaust parts. The corresponding two positions in the two rows of connecting short plates are slidably matched with the two vertical positioning shafts through spring pushing.

[0019] Furthermore,

[0020] The exhaust member is in a transverse strip structure, and the top ends of the left and right vertical support side rods of the force-bearing frame are welded and fixed to two corresponding positions in a row of connecting short plates.

[0021] Furthermore,

[0023] Furthermore,

[0024] A drain pipe is hoisted at the bottom of the steam buffer cylinder, the left and right ends of the drain pipe are vertically bent, and a row of vertical short drain pipes are welded to the top of the drain pipe, and the top of the row of vertical short drain pipes is welded and connected to a row of leakage holes;

[0025] The top ends of the left and right vertical bends of the steam buffer cylinder are both open structures.

[0032] The buffer device for a sterilizing cabinet provided by the present invention has the following beneficial effects:

[0033] During use of the present invention, when the conical plugging cover is pushed to the right by the steam, it can drive the longitudinal sliding shaft and the pushing plate to move together. Through the inclined guiding principle of the inclined part of the pushing plate, the force frame can be pressed downward to slide, thereby controlling a row of exhaust parts to disengage and open from a row of blocking rods. When the steam input stops, the longitudinal sliding shaft and the pushing plate are driven by the conical plugging cover to slide to the right and disengage from the force frame, so that the row of exhaust parts loses the downward pushing holding force and can be automatically pushed up by the springs on the two vertical positioning shafts to slide and close against the row of blocking rods. This can save the trouble of manually switching the row of exhaust parts before and after steam input during loading and unloading, and is more convenient to operate and use than the prior art.

[0034] In addition, when a row of exhaust parts are indirectly pushed down and opened by air pressure, they need to compress to overcome the thrust of the springs on the two vertical positioning shafts. This will further consume the circulation kinetic energy of the high-temperature steam, further buffer, decelerate and reduce the pressure of the steam, which is beneficial to improving the buffering effect on the steam.

[0035] In addition, when a row of exhaust parts is closed, the row of exhaust parts protrudes from the top of the steam buffer cylinder, and the oblique sections on the left and right sides of the V-shaped groove are connected with the tapered section on the upper side of the blocking rod to form two downward-extending and enlarged inclined material guide surfaces. The downward-extending and enlarged inclined material guide surfaces can guide the materials or debris that fall on the top thereof downward, preventing the fallen materials or debris from accumulating on the top part of the row of exhaust parts, and falling into and blocking the row of exhaust parts when sliding downward to open, which helps to indirectly ensure the steam buffer cylinder's effect of preventing falling objects from entering before and after loading and unloading.

[0036] In addition, under normal conditions, water is stored inside a row of short vertical downpipes and in the left and right vertical bends of the drain pipes, and the water levels are kept at the same height. The stored water can act as a water seal for the steam, preventing steam from leaking from a row of leakage holes to the bottom and preventing it from directly contacting the rising materials for sterilization, resulting in certain losses and consumption, which is beneficial to improving the effective utilization of steam.

[0037] In addition, by loosening the tightening bolt, the steam buffer cylinder can be turned downward around the air inlet pipe through the collar, and the materials or debris that have fallen on the top of the steam buffer cylinder between a row of exhaust parts can be turned upside down and cleaned up at one time. The operation is convenient and easy to use. When the steam buffer cylinder is in a turned-over state, the steam buffer cylinder can be repeatedly deflected back and forth, so that the limit block and the stopper can intermittently impact and contact with each other at a higher frequency, and the impurities that are stuck to the top of the steam buffer cylinder and have not been cleaned up by turning it upside down can be thoroughly cleaned by vibration and falling.

[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0063] Example 1, please refer to Figures 1 to 8

[0064] The present invention proposes a buffer device for a sterilizing cabinet, comprising a steam buffer cylinder 1; the steam buffer cylinder 1 is installed at the bottom side of the sterilizing cabinet to distribute high-temperature sterilizing steam upward;

[0065] A row of exhaust members 102 are slidably installed on the top wall of the steam buffer cylinder 1 at equal intervals. The internal hollow top opening of the exhaust member 102 is used to discharge the internal steam of the steam buffer cylinder 1 upward, and a row of blocking rods 101 are welded at equal intervals above the top of the steam buffer cylinder 1; the row of exhaust members 102 are positioned by spring pushing. Under normal circumstances, the exhaust members 102 are slid upward by the spring to abut against the blocking rods 101, which can prevent materials or debris that fall before and after loading and unloading from entering the steam buffer cylinder 1 or blocking the row of exhaust members 102; the bottom side parts of the row of exhaust members 102 are fixed together and can be slid up and down synchronously; an air inlet pipe 7 is welded through the bottom side of the right side wall of the sterilization cabinet, and the head end of the air inlet pipe 7 is connected to the air inlet;

[0066] A conical plugging cover 2 is slidably installed inside the steam buffer cylinder 1. Under normal circumstances, the conical plugging cover 2 is pressed against and blocked on the air inlet at the right end of the steam buffer cylinder 1; at least one transverse positioning shaft 107 is welded in the right side of the steam buffer cylinder 1; at least two inclined curved rods 203 are symmetrically rotatably connected to the front and rear sides of the conical plugging cover 2, and the tail end of each curved rod 203 is rotatably connected to a shaft sleeve 204, and the two shaft sleeves 204 are slidably matched with the transverse positioning shaft 107 through spring pushing; the center of the conical plugging cover 2 A longitudinal sliding shaft 201 supporting to the left is welded therein, and the longitudinal sliding shaft 201 is installed in the center with a limit position; a U-shaped force frame 108 is welded and hoisted at the bottom of a row of exhaust components 102, and a horizontally longitudinally arranged push plate 205 is welded at the bottom of the middle section of the longitudinal sliding shaft 201, and the front end of the push plate 205 is supported in an upward tilt; the inclined part of the push plate 205 is in contact with the bottom horizontal part of the force frame 108; when pressurized steam is input into the right end air inlet of the steam buffer cylinder 1, the conical plug cover 2 is pushed open;

[0067] It is worth noting that: the transverse positioning shafts 107 are preferably at two locations, the bent rods 203 are preferably at four locations, and for the convenience of description, the number of bent rods 203 is four locations, the number of transverse positioning shafts 107 is two locations, and the number of sleeves 204 is four locations;

[0068] The four crank rods 203, the four shaft sleeves 204 and the conical plug cover 2 are connected together to form a four-way crank slider mechanism. Through this four-way mechanism, the left and right sliding conical plug cover 2 can drive the four shaft sleeves 204 to slide back and forth, and the four shaft sleeves 204 are kept in position by the pushing force of the two springs mounted on the two transverse positioning shafts 107. When the conical plug cover 2 is pressed to the right by the input steam to slide to open the air inlet, the four shaft sleeves 204 are driven to slide close to each other. In this process, the four shaft sleeves 204 need to overcome the pushing and holding force of the springs on the two transverse positioning shafts 107 and consume the circulation kinetic energy of the high-temperature steam, so as to implement buffering, deceleration and pressure reduction for the steam.

[0069] When the conical plugging cover 2 is pushed to the right by the steam, the longitudinal sliding shaft 201 and the push plate 205 can be driven to move together. Through the inclined guiding principle of the inclined part of the push plate 205, the force frame 108 can be pushed downward to slide, thereby controlling a row of exhaust parts 102 to separate and open from a row of blocking rods 101. When the steam input stops, the conical plugging cover 2 and the four shaft sleeves 204 lose the air pressure push, and the springs on the two horizontal positioning shafts 107 can rebound to push the four shaft sleeves 204 away from each other and return to their original positions, thereby controlling the conical plugging cover 2 to move downward. The blocking cover 2 slides to the right to reset and close the air inlet, and in this process, the longitudinal sliding shaft 201 and the push plate 205 are driven by the conical blocking cover 2 to slide to the right and disengage from the force frame 108, so that the row of exhaust members 102 lose the downward pushing holding force, and can be automatically pushed up by the springs on the two vertical positioning shafts 105 to slide against the row of blocking rods 101 for closing, thereby eliminating the need to manually open and close the row of exhaust members 102 before and after steam input during loading and unloading, and is more convenient to operate and use than the prior art;

[0070] In addition, when a row of exhaust parts 102 are indirectly pushed down and opened by air pressure, they need to compress to overcome the thrust of the springs on the two vertical positioning shafts 105, which will further consume the circulation kinetic energy of the high-temperature steam, further implement buffering, deceleration and pressure reduction on the steam, which is beneficial to improving the buffering effect on the steam.

[0071] Specifically,

[0072] The blocking rod 101 is a diamond-shaped structure with tapered ends at the top and bottom. A V-shaped slot is provided on the top opening of the exhaust member 102, and the V-shaped slot is plugged into the tapered portion at the bottom of the blocking rod 101.

[0073] The top of the exhaust piece 102 is located on the left and right sides of the V-shaped groove and is an oblique structure. When the V-shaped groove slides up and is engaged with the lower conical structure of the blocking rod 101 to close a row of exhaust pieces 102, a row of exhaust pieces 102 protrudes from the top of the steam buffer cylinder 1, and the oblique sections on the left and right sides of the V-shaped groove are connected with the conical section on the upper side of the blocking rod 101 to form two downward-extending and enlarged inclined guide surfaces. The downward-extending and enlarged inclined guide surfaces can guide the materials or debris that fall on the top thereof downward, avoiding the fallen materials or debris from accumulating on the top part of a row of exhaust pieces 102. When they slide downward to open, they fall into and block a row of exhaust pieces 102, which helps to indirectly ensure the effect of preventing falling objects from entering the steam buffer cylinder 1 before and after loading and unloading.

[0074] Specifically,

[0075] A rectangular support frame 202 is sleeved and welded on the conical blocking cover 2, and the tail ends of the two bent rods 203 are rotatably matched with the vertical support shaft rods on the front and rear sides of the rectangular support frame 202.

[0076] Specifically,

[0077] A vertical support ear plate 106 is welded on the bottom plate of the steam buffer cylinder 1 at the middle position in the front-to-back direction, and the longitudinal sliding shaft 201 penetrates and slides with the vertical support ear plate 106;

[0078] The air inlet pipe 7 is connected to the air inlet port by screw locking.

[0079] Specifically,

[0080] Two vertical positioning shafts 105 are welded symmetrically in the middle position of the left and right directions inside the steam buffer cylinder 1, and two rows of connecting short plates 104 are symmetrically welded between the bottom parts of a row of exhaust parts 102. The two corresponding positions in the two rows of connecting short plates 104 are slidably matched with the two vertical positioning shafts 105 through spring pushing.

[0081] Specifically,

[0082] The exhaust member 102 is in a transverse strip structure, and the top ends of the left and right vertical support side bars of the force-bearing frame 108 are welded and fixed to two corresponding positions in a row of connecting short plates 104 .

[0083] Specifically,

[0084] A row of longitudinally arranged water leakage holes 103 is formed through the middle of the bottom plate of the steam buffer cylinder 1 , and the condensed water inside the steam buffer cylinder 1 leaks downward through the row of water leakage holes 103 .

[0085] On the basis of the first embodiment, the second embodiment, as Fig. 9 - Fig.10 As shown:

[0086] A drain pipe 3 is hoisted at the bottom of the steam buffer cylinder 1. The left and right ends of the drain pipe 3 are vertically bent structures, and a row of vertical short drain pipes 301 are welded to the top of the drain pipe 3. The top of the row of vertical short drain pipes 301 is welded and connected to a row of leakage holes 103.

[0087] The tops of the left and right vertical bends of the steam buffer cylinder 1 are both open structures. The condensed water inside the steam buffer cylinder 1 is discharged through a row of water leakage holes 103, a row of vertical short water discharge pipes 301 and the left and right vertical bends of the drain pipe 3 in sequence. In a normal state, water is stored inside a row of vertical short water discharge pipes 301 and the left and right vertical bends of the drain pipe 3, and the water level is kept at the same height. The stored water can act as a water seal for the steam, preventing the steam from leaking from the row of water leakage holes 103 to the bottom, and preventing the steam from directly contacting the rising materials for sterilization, resulting in a certain loss and consumption, which is conducive to improving the effective utilization rate of the steam.

[0088] When condensate flows into the vertical short drain pipe 301, the water level inside it rises according to the water pressure formula p=ρgh. The downward water pressure in the vertical short drain pipe 301 increases, which can press the water in the left and right vertical bending parts of the drain pipe 3 outward, thereby completing the normal discharge of condensate.

[0089] Embodiment three, as Fig.11 - Fig.13 As shown:

[0090] A collar 109 is welded on the right wall of the steam buffer cylinder 1 at the position of the air inlet, the air inlet pipe 7 and the collar 109 penetrate and slide in cooperation, and the collar 109 and the steam buffer cylinder 1 can rotate around the air inlet pipe 7;

[0091] A tightening bolt 4 is screwed through the bottom side of the left side wall of the sterilization cabinet, and the head end of the tightening bolt 4 is in contact with the left side wall of the steam buffer cylinder 1 to press and seal the air inlet and the head end of the air inlet pipe 7 together, and position the steam buffer cylinder 1 and a row of exhaust parts 102 in a horizontal state for distributing steam. After loosening the tightening bolt 4, the steam buffer cylinder 1 can be turned downward around the air inlet pipe 7 through the ring 109, and the materials or debris that fall on the top of the steam buffer cylinder 1 between the row of exhaust parts 102 can be turned upside down and cleaned up at one time, which is convenient to operate and use.

[0092] Specifically,

[0093] A hand-held rotating ring 5 is welded on the left end of the steam buffer cylinder 1, and a limit block 501 is welded on the hand-held rotating ring 5. The hand-held rotating ring 5 can be used to drive the steam buffer cylinder 1 to swing up and down.

[0094] A stopper 6 is welded on the bottom plate of the sterilization cabinet. When the steam buffer cylinder 1 is flipped downward, the limit block 501 abuts against the stopper 6. When the steam buffer cylinder 1 is in a flipped and inverted state, the steam buffer cylinder 1 can be repeatedly deflected back and forth, so that the limit block 501 and the stopper 6 intermittently impact contact at a higher frequency, and the impurities adhering to the top of the steam buffer cylinder 1 that have not been cleaned up by turning it upside down are thoroughly vibrated and dropped to be cleaned.

[0095] The overall working principle of the present invention is as follows: when in use, high-temperature steam enters the steam buffer cylinder 1 through the air inlet pipe and the air inlet port, and the internal hollow top opening of a row of exhaust members 102 is used to discharge the internal steam of the steam buffer cylinder 1 upward. Under normal conditions, the exhaust members 102 are slid upward by the spring to abut against the blocking rod 101 to prevent materials or debris that fall before and after loading and unloading from entering the steam buffer cylinder 1 or blocking the row of exhaust members 102;

[0096] The four crank rods 203, the four shaft sleeves 204 and the conical plug cover 2 are connected together to form a four-way crank slider mechanism. Through this four-way mechanism, the left and right sliding conical plug cover 2 can drive the four shaft sleeves 204 to slide back and forth, and the four shaft sleeves 204 are kept in position by the pushing force of the two springs mounted on the two transverse positioning shafts 107. When the conical plug cover 2 is pressed to the right by the input steam to slide to open the air inlet, the four shaft sleeves 204 are driven to slide close to each other. In this process, the four shaft sleeves 204 need to overcome the pushing and holding force of the springs on the two transverse positioning shafts 107 and consume the circulation kinetic energy of the high-temperature steam, so as to implement buffering, deceleration and pressure reduction for the steam.

[0097] When the conical plugging cover 2 is pushed to the right by the steam, it can drive the longitudinal sliding shaft 201 and the pushing plate 205 to move together. Through the inclined guiding principle of the inclined part of the pushing plate 205, the force frame 108 can be pushed downward to slide, thereby controlling a row of exhaust parts 102 to move downward and separate from a row of blocking rods 101 to open. When the steam input stops, the conical plugging cover 2 and the four shaft sleeves 204 lose the air pressure push. The springs on the two horizontal positioning shafts 107 can rebound to push the four shaft sleeves 204 away from each other and control the conical plugging cover 2 to slide rightward to reset and close the air inlet. In this process, the longitudinal sliding shaft 201 and the pushing plate 205 are driven by the conical plugging cover 2 to slide rightward and separate from the force frame 108, so that a row of exhaust parts 102 loses the downward pushing holding force and can be automatically pushed upward by the springs on the two vertical positioning shafts 105 to slide against a row of blocking rods 101 to close.

[0098] In addition, when a row of exhaust members 102 is indirectly pushed and slid open by air pressure, it needs to compress to overcome the thrust of the springs on the two vertical positioning shafts 105, which will further consume the circulation kinetic energy of the high-temperature steam and further implement buffering, deceleration and pressure reduction on the steam;

[0099] The condensed water inside the steam buffer cylinder 1 is discharged in turn through a row of leakage holes 103, a row of vertical short drain pipes 301 and the left and right vertical bends of the drain pipe 3. The specific process is that when the condensed water flows into the vertical short drain pipe 301, the water level inside it rises. According to the water pressure formula p=ρgh, the downward water pressure in the vertical short drain pipe 301 increases, and the water in the left and right vertical bends of the drain pipe 3 can be pressed outward, thereby completing the normal discharge of the condensed water.
