Description

Technical Field

[0001] The invention belongs to the technical field of heat exchangers, in particular to a high-efficiency plate-belt heat exchanger and a use method thereof. Background Art

[0002] A plate heat exchanger is a heat exchange device composed of a series of stacked metal sheets with a certain corrugated shape; thin rectangular channels are formed between these metal sheets, and heat is exchanged through the plates. It is suitable for liquid-liquid and liquid-steam heat exchange; the plate heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life.

[0003] In the prior art, after a plate heat exchanger has been working for a long time, scale will be present on the surface of the heat exchange plate, which will greatly affect the heat exchange efficiency and needs to be cleaned. In order to prevent the error of disassembly and reinstallation from causing water leakage, it will be cleaned directly with a high-pressure water gun without disassembly. However, there is the following problem: when a high-pressure water gun is used for cleaning without disassembly, the heat exchange plate is relatively thin and the impact force of the high-pressure water gun is relatively large. When the heat exchange plate is impacted, the heat exchange plate will be slightly deformed due to the impact of the large impact force.

The motor screw drives the second slider and the first slider to move to a suitable position, and then the heat exchange plates are spread out in sequence.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 14As shown, a high-efficiency plate-belt heat exchanger described in an embodiment of the present invention comprises a fixed end plate 1 and a movable end plate 11; a fixed rod 12 and a bottom rod 15 are fixedly connected to the side wall of the fixed end plate 1, and the fixed rod 12 is located above the bottom rod 15; a guide rail 13 is fixedly connected to the bottom end of the fixed rod 12; a group of heat exchange plates 14 slide on the guide rail 13; a first slider 16 is slidably connected to the fixed rod 12, and a second slider 17 is slidably connected to the bottom rod 15; the first slider 16 and the second slider 17 are fixedly connected between the middle parts of the side walls on both sides by a U-shaped guide rod 2; a pair of first slide grooves 22 symmetrically distributed about the U-shaped guide rod 2 are provided on the side walls on both sides of the first slider 16 and the second slider 17; a U-shaped rod 21 is slidably connected between the first slide grooves 22 opposite to each other in upper and lower positions of the first slider 16 and the second slider 17; a handle 64 is fixedly connected to the outer wall of the U-shaped rod 21; A supporting mechanism is provided on the inner wall of 21; the U-shaped rod 21 is fixed in the first slide groove 22 by a locking member; a first cavity 23 is provided in the first slider 16; a pair of symmetrically distributed first through grooves 24 are provided at the bottom end of the first cavity 23; a high-pressure water spraying member is provided in the first through groove 24; a pair of through grooves 25 are provided in the first slider 16 and the second slider 17, and the through grooves 25 allow the first slide grooves 22 at the relative positions on both sides of the first slider 16 and the second slider 17 to pass through; a first gear 27 is rotatably connected in the through groove 25; a first rack plate 26 is fixedly connected to the end of the U-shaped rod 21 located in the first slide groove 22, and a pair of first rack plates 26 on the ends of the U-shaped rod 21 symmetrically distributed about the fixed rod 12 are staggered up and down, and the staggered first rack plates 26 are meshed with the first gear 27; the second slider 17 slides through the motor screw 28;In the prior art, after the plate heat exchanger has been working for a long time, scale will exist on the surface of the heat exchange plate, which will greatly affect the heat exchange efficiency and needs to be cleaned. In order to prevent the error of disassembly and reinstallation from causing the water source to be missed, it will be cleaned directly with a high-pressure water gun without disassembly. However, there are the following problems: when the high-pressure water gun is used for cleaning directly without disassembly, because the heat exchange plate is thin, the impact force of the high-pressure water gun is large. When the heat exchange plate is impacted, it will cause the heat exchange plate to be slightly deformed due to the impact of the large impact force. For this reason, when the present invention is working, when it is necessary to clean the heat exchange plate 14 without disassembly (the cleaning agent will flow in the early stage), the pressing screw (not described in the prior art) is removed first, and then the movable end plate 11 can be moved to allow the closely attached heat exchange plate 14 to be dispersed, and the motor is used to move the end plate 11 to move the end plate 11 to move the closely attached heat exchange plate 14 to move the end plate 1 ... The lead screw 28 drives the second slider 17 and the first slider 16 to move to the appropriate position, and then the heat exchange plates 14 are spread out in turn, first allowing one heat exchange plate 14 to enter between a pair of U-shaped rods 21, and then allowing another heat exchange plate 14 to enter between another pair of U-shaped rods 21, and then using the support mechanism to support the heat exchange plate 14 at this time. At this time, the high-pressure water spraying part will be located between a pair of heat exchange plates 14, and then the high-pressure water spraying part is moved down for spraying. Because the heat exchange plate 14 is supported by the support mechanism, the impact force of the high-pressure water spraying part will not cause the heat exchange plate 14 to deform. After water spraying and cleaning, the heat exchange plates 14 are cleaned in turn, which can ensure efficient cleaning, and can fully clean both sides of the heat exchange plate 14 to ensure the cleaning effect. The motor lead screw 28 is driven by the motor to rotate the lead screw, and then the lead screw is used to drive the second slider 17 to move. ;

[0039] The high-pressure water spraying member includes a guide groove 3 and a circular plate 31; a circular plate 31 is provided in the first through groove 24, and a guide groove 3 is provided on the side wall of the circular plate 31; the guide groove 3 is slid on the vertical rod of the U-shaped guide rod 2; a double-axis motor 32 is fixedly connected to the middle of the bottom of the first cavity 23, and a rope reel 33 is provided at both sides of the output end of the double-axis motor 32, and the rope reel 33 and the circular plate 31 are connected by a suspension rope 34; a water spraying pipe 35 is provided near the bottom of the inner wall of the circular plate 31, and a pair of symmetrically distributed water spraying heads are embedded on the outer peripheral wall of the water spraying pipe 35, and the water spraying heads are tilted downward; a telescopic hose 36 is fixedly connected to the top of the water spraying pipe 35, and the telescopic hose 3 6 is fixedly connected to and extends out of the top of the first slider 16, the telescopic hose 36 and the water spray pipe 35 are interconnected, and the top of the telescopic hose 36 is connected to the external high-pressure water pipe; during operation, when the heat exchange plate 14 needs to be cleaned, the valve of the external high-pressure water pipe is opened to allow high-pressure water to flow into the telescopic hose 36 and the water spray pipe 35. At this time, the double-axis motor 32 is started, and the circular plate 31 has a counterweight effect, allowing the circular plate 31 and the water spray pipe 35 to move downward as a whole. At the same time, the telescopic hose 36 is retractable and will not affect the up and down movement of the water spray pipe 35. The circular plate 31 and the water spray pipe 35 are located between the pair of heat exchange plates 14 placed, so that they can be fully cleaned when the water spray pipe 35 moves downward.

[0040] The supporting mechanism includes a first rotating shaft 41; a first groove 4 is opened on the inner side of the vertical wall of the U-shaped rod 21; a group of first rotating shafts 41 are rotatably connected on the inner wall of the first groove 4; a second gear 42 is fixedly connected to the first rotating shaft 41; a semicircular plate 44 is fixedly connected to the side wall of the second gear 42; an inverted L-shaped tooth plate 43 is slidably connected to the side wall of the first groove 4, and the vertical plate of the inverted L-shaped tooth plate 43 and the second gear 42 are meshed with each other, and the inverted L-shaped tooth plate 43 passes through the top end of the U-shaped rod 21, and the inverted L-shaped tooth plate 43 moves up and down through the lifting member; the supporting mechanisms in a pair of U-shaped rods 21 are symmetrically arranged about the U-shaped guide rod 2.

[0041] The lifting member includes a moving plate 45; a pair of symmetrically distributed second through slots 46 are provided on both side walls of the first cavity 23; the top of the moving plate 45 is fixedly connected to the top of the first cavity 23 through a spring, and the bottom of the moving plate 45 contacts the top of the circular plate 31; the horizontal rod of the inverted L-shaped tooth plate 43 extends into the first cavity 23 through the second through slot 46 and penetrates and slides in the moving plate 45;

[0042] Initially, the hanging rope 34 is in a tightened state, and the circular plate 31 squeezes the movable plate 45 under the action of the hanging rope 34, thereby making the spring on the movable plate 45 in a compressed state. When the circular plate 31 moves downward as a whole, the movable plate 45 loses the support of the circular plate 31, and the movable plate 45 moves downward under the action of the spring elastic force, thereby driving the inverted L-shaped toothed plate 43 to move downward. Because the inverted L-shaped toothed plate 43 and the second gear 42 are meshed with each other, the second gear 42 is driven to rotate, and the semicircular plate 44 follows the second gear 42 to rotate, so that the semi-arc surface of the semicircular plate 44 can fit on the side wall of the heat exchange plate 14, ensuring the heat exchange The supporting force of the heat plate 14, and after the later flushing is completed, when the circular plate 31 returns to its original position (the dual-axis motor 32 drives the circular plate 31 to return to its original position through the suspension rope 34), the upward movement of the circular plate 31 will cause the movable plate 45 to move upward, thereby driving the inverted L-shaped tooth plate 43 to move upward, allowing the second gear 42 to rotate in the opposite direction, allowing the semicircular plate 44 to vertically enter the first groove 4 again for storage, releasing the support, and thus facilitating the subsequent operation of the heat exchange plate 14 (when flushing, a pair of heat exchange plates 14 are located between the two groups of semicircular plates 44, and the arc-shaped surfaces of the semicircular plates 44 are in contact with the side walls of the heat exchange plates 14).

[0043] An extrusion plate 52 is fixedly connected to the side wall of the first groove 4 through a spring, and the first rotating shaft 41 passes through the extrusion plate 52; a push column 51 is fixedly connected to the side walls of the upper and lower ends of the extrusion plate 52, and the push column 51 extends out of the U-shaped rod 21; a pair of symmetrically distributed right-angled trapezoidal blocks 5 are fixedly connected to the side walls of both sides of the first slider 16 and the second slider 17, and the ends of the push column 51 and the inclined surfaces of the right-angled trapezoidal blocks 5 are in contact with each other; a rubber layer 53 is fixedly connected to the side wall of the extrusion plate 52 away from the push column 51;

[0044] After using the semicircular plate 44 for support, the single-sided U-shaped rod 21 is manually pushed, and then the first rack plate 26 and the first gear 27 are used to make the corresponding pair of U-shaped rods 21 move toward each other. When the U-shaped rods 21 move toward each other, the pushing column 51 will move along the inclined surface of the right-angled trapezoidal block 5, so that the squeezing plate 52 can be moved, and the side of the heat exchange plate 14 can be squeezed, thereby completing the squeezing of the side walls of the heat exchange plate 14, so that the heat exchange plate 14 is in a stable state, which can effectively reduce the effect of the impact rebound force on the heat exchange plate 14, and at the same time ensure the stable impact operation of the heat exchange plate 14, further ensure the cleaning effect and reduce the impact damage to the heat exchange plate 14.

[0045] A pair of positioning grooves 6 are provided on the top of the first slide groove 22 of the first slider 16 and the bottom of the first slide groove 22 of the second slider 17; a second groove 61 is provided on the top and bottom of the U-shaped rod 21; a positioning block 63 is fixedly connected to the bottom of the second groove 61 through a spring; an electromagnetic block 62 is fixedly connected to the bottom of the second groove 61; when the electromagnetic block 62 is energized through the power supply, the electromagnetic block 62 and the positioning block 63 attract each other;

[0046] The power supply member includes a moving rod 65; the handle 64 is U-shaped, and the moving rod 65 is slidably connected to the inner wall of the handle 64; a negative pole 66 is fixedly connected to the inner wall of the handle 64; a positive pole 67 is fixedly connected to the side wall of the moving rod 65; the moving rod 65 is fixedly connected to the side wall of the handle 64 through a spring;

[0047] When the column handle 64 and the moving rod 65 are manually grasped, the moving rod 65 moves to make the negative pole 66 and the positive pole 67 fit together, so that the electromagnetic blocks 62 on the relative U-shaped rod 21 are energized, so that the locking block 63 is adsorbed and separated from the locking groove 6, so as to facilitate the movement of the U-shaped rod 21. At the same time, after the heat exchange plate 14 is clamped or released, the position of the U-shaped rod 21 is guaranteed to be stable (each first slide groove 22 has a pair of locking grooves 6 in order to fix the U-shaped rod 21 in different states).

[0048] The water spray pipe 35 is composed of a first cylinder 7 and a second cylinder 71; one side of the first cylinder 7 is in an open state, and the second cylinder 71 is sealingly slidably connected to the inner wall of the opening of the first cylinder 7, and the opening of the second cylinder 71 and the opening of the first cylinder 7 are connected to each other; a pair of second slide grooves 72 are provided on the inner wall of the first cylinder 7; a pair of moving blocks 73 are fixedly connected to the outer wall of the second cylinder 71, and the moving blocks 73 are slidably connected in the second slide grooves 72, and the moving blocks 73 are fixedly connected to the side walls of the second slide grooves 72 through springs; the outer wall of the first cylinder 7 is slidably connected to the inner wall of the circular plate 31 through a slide groove slide rod 74; the first cylinder 7 moves back and forth through a circulating member;

[0049] Because the water spray pipe 35 is composed of the first cylinder 7 and the second cylinder 71, when no water flows, the second cylinder 71 is contracted in the first cylinder 7, and after the high-pressure water enters the first cylinder 7, the second cylinder 71 is extended under the impact of the water pressure, so that the pair of water spray pipes 35 can fully cover the width surface of the heat exchange plate 14 (due to the separation of the guide rail 13 and the fixed rod 12, the extension of the second cylinder 71 can cover the entire heat exchange plate 14). After the water spraying is completed in the later stage, due to the absence of the impact of the high-pressure water, the second cylinder 71 is retracted into the first cylinder 7 again, so that the entire water spray pipe 35 can enter the first through groove 24 (if the water spray pipe 35 is located below the fixed rod 12 and the guide rail 13, it will affect the subsequent fitting of the heat exchange plate 14).

[0050] The circulating member includes a third groove 75; the guide groove 3 is T-shaped when viewed from above, and the side wall of the guide groove 3 and the circular plate 31 are interconnected; the vertical rod of the U-shaped guide rod 2 is T-shaped when viewed from above, and the U-shaped guide rod 2 is slidably connected in the guide groove 3; a third groove 75 is provided on the side wall of the U-shaped guide rod 2, and straight grooves 76 and corrugated grooves 77 are provided on the inner walls on both sides of the third groove 75, and the straight groove 76 is located above the corrugated groove 77, and the straight groove 76 and the corrugated groove 77 are interconnected; a push rod 78 is fixedly connected to the side wall of the first cylinder 7, and the push rod 78 slides in the third groove 75, and a rotating column 79 is rotatably connected to the push rod 78, and the two sides of the rotating column 79 are slidably connected in the straight groove 76 and the corrugated groove 77;

[0051] When the water spray pipe 35 and the circular plate 31 move downward as a whole, after the rotating column 79 enters the corrugated groove 77 in the straight groove 76, the setting of the corrugated groove 77 can allow the push rod 78 and the water spray pipe 35 to move left and right as a whole, thereby increasing the spraying area and further ensuring the cleaning effect. The corrugated grooves 77 in each U-shaped guide rod 2 have the same corrugation direction, and a pair of water spray pipes 35 move left and right in the same direction under the action of the corrugated grooves 77, instead of moving in opposite directions.

[0052] A method for using a high-efficiency plate-belt heat exchanger is provided. The method is applicable to the high-efficiency plate-belt heat exchanger mentioned above. The steps of the method are as follows:

[0053] S1: The second slider 17 and the first slider 16 are driven to move to a suitable position by the motor screw 28, and then the heat exchange plates 14 are spread out in sequence, firstly one heat exchange plate 14 is allowed to enter between a pair of U-shaped rods 21, and then another heat exchange plate 14 is allowed to enter between another pair of U-shaped rods 21;

[0054] S2: The heat exchange plates 14 are supported by a supporting mechanism, and the high-pressure water spraying member is located between a pair of heat exchange plates 14, and then the high-pressure water spraying member is moved downward for spraying and cleaning.

[0055] Principle: When the heat exchange plate 14 needs to be cleaned, open the valve of the external high-pressure water pipe to allow high-pressure water to flow into the telescopic hose 36 and the water spray pipe 35. At this time, the dual-axis motor 32 is started, and the circular plate 31 has a counterweight effect, allowing the circular plate 31 and the water spray pipe 35 to move downward as a whole. At the same time, the telescopic hose 36 is retractable and will not affect the up and down movement of the water spray pipe 35. The circular plate 31 and the water spray pipe 35 are located between a pair of heat exchange plates 14, so that they can be fully cleaned when the water spray pipe 35 moves downward. Initially, the hanging rope 34 is in a tightened state, and the circular plate 31 squeezes the movable plate 45 under the action of the hanging rope 34, thereby compressing the spring on the movable plate 45. In this state, when the circular plate 31 moves downward as a whole, the movable plate 45 loses the support of the circular plate 31, and the movable plate 45 will move downward under the action of the spring force, thereby driving the inverted L-shaped toothed plate 43 to move downward. Because the inverted L-shaped toothed plate 43 and the second gear 42 are meshed with each other, the second gear 42 is driven to rotate, and the semicircular plate 44 follows the second gear 42 to rotate, so that the semi-arc surface of the semicircular plate 44 can fit on the side wall of the heat exchange plate 14 to ensure the support force for the heat exchange plate 14. After the later flushing is completed, when the circular plate 31 returns to its original position (the dual-axis motor 32 drives the circular plate 31 to return to its original position through the suspension rope 34), the upward movement of the circular plate 31 will cause the movable plate 45 to move upward, and the The inverted L-shaped toothed plate 43 is driven to move upward, and the second gear 42 rotates in the opposite direction, so that the semicircular plate 44 is vertically inserted into the first groove 4 again for storage, and the support is released, so that the subsequent heat exchange plate 14 operation can be conveniently performed; after the semicircular plate 44 is used for support, the single-sided U-shaped rod 21 is manually pushed, and then the first rack plate 26 and the first gear 27 are used to make the corresponding pair of U-shaped rods 21 move toward each other. When the U-shaped rods 21 move toward each other, the pushing column 51 will move along the inclined surface of the right-angled trapezoidal block 5, so that the squeezing plate 52 can move, and the side edge of the heat exchange plate 14 can be squeezed, thereby completing the two sides of the heat exchange plate 14. The extrusion of the side wall keeps the heat exchange plate 14 in a stable state, which can effectively reduce the impact rebound force on the heat exchange plate 14, and at the same time ensure the stable impact operation of the heat exchange plate 14, further ensuring the cleaning effect and reducing the impact damage to the heat exchange plate 14; when the column handle 64 and the moving rod 65 are manually gripped, the moving rod 65 moves at this time, so that the negative pole column 66 and the positive pole column 67 fit each other, so that the electromagnetic blocks 62 on the relative U-shaped rod 21 are energized, so that the positioning block 63 is adsorbed and separated from the positioning slot 6, so as to facilitate the movement of the U-shaped rod 21, and at the same time, after the subsequent clamping or subsequent release of the heat exchange plate 14, the position of the U-shaped rod 21 is ensured to be stable;Because the water spray pipe 35 is composed of the first cylinder 7 and the second cylinder 71, when no water is passed, the second cylinder 71 is retracted in the first cylinder 7, and after the high-pressure water enters the first cylinder 7, the second cylinder 71 is extended under the impact of the water pressure, so that the pair of water spray pipes 35 can fully cover the width surface of the heat exchange plate 14 (due to the separation of the guide rail 13 and the fixed rod 12, the extension of the second cylinder 71 can cover the entire heat exchange plate 14). After the water spraying is completed in the later stage, due to the absence of the impact of high-pressure water, the second cylinder 71 is retracted into the first cylinder 7 again, so that the entire water spray pipe 35 can enter the first through groove 24 (if the water spray pipe 35 is located below the fixed rod 12 and the guide rail 13, it will affect the subsequent fitting of the heat exchange plate 14). ;
