Description

Technical Field

[0001] This invention relates to the field of drying technology, specifically to an air-source heat pump dryer capable of sterilization and disinfection. Background Technology

[0002] Dryers generally use high-temperature heat pumps for high-temperature drying. High-temperature heat pumps refer to heat pumps whose heating water temperature and air temperature can reach above 80 degrees Celsius. Currently, four types of heat pumps have been developed for heating water temperature, including medium-high temperature heat pumps that use 45-degree waste water and heat water temperature of 85 degrees Celsius, and high-temperature heat pumps that use 80-degree waste water and produce 150-degree steam.

[0003] This patent, application number CN201710697592.0, provides a centrifugal high-temperature heat pump, including a multi-stage compressor, a drive unit, and N steam-water heat exchangers. The multi-stage compressor includes a housing, a rotating shaft disposed within the housing, and N impellers fixed on the rotating shaft. The housing is divided into N segments, each segment containing one impeller, and each segment of the housing and the impeller within each segment constitute one stage of the multi-stage compressor. One end of the rotating shaft passes through the housing and is connected to the drive unit. Each stage of the multi-stage compressor corresponds to one steam-water heat exchanger and is connected to the corresponding steam-water heat exchanger. The N steam-water heat exchangers are sequentially connected; N ≥ 3 and is an integer. It achieves cascade heating of primary water, making the heat transfer process more matched and the heat exchange efficiency more efficient. Condensation heat exchange only occurs in the steam-water heat exchangers, resulting in fewer heat exchange processes and less heat loss, effectively improving the energy efficiency ratio of the high-temperature heat pump. Furthermore, it directly compresses the exhaust gas after power generation, fully utilizing the waste heat from steam power generation, thus saving energy and protecting the environment.

[0004] During the use of the aforementioned sterilizable air-source heat pump dryer, agricultural products were not turned over in time when they entered the dryer for drying, resulting in uneven heating of the agricultural products. Therefore, a sterilizable air-source heat pump dryer is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an air-source dryer that can sterilize and disinfect, addressing the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an air-source heat pump dryer capable of sterilization and disinfection, comprising a dryer body, a material feeding device provided on the inner wall of the dryer body, a water scraping device provided on the inner wall of the dryer body, and a collection and discharge device provided on the inner wall of the dryer body; the material feeding device includes a motor, a reciprocating lead screw, a material feeding rake, a roller, a cam, a round block, a material feeding plate, a fixed support plate, a material feeding rod, a pulley set, a reciprocating lead screw, a material loading box, a fixed rod, and a rotating rod; the motor is fixedly connected to the right side of the dryer body, the reciprocating lead screw is fixedly connected to the output end of the motor, and the material feeding rake is threadedly connected to the reciprocating lead screw. When the sterilizing air-source heat pump dryer is started, motor one drives reciprocating screw one to rotate. The cross-shaped spiral groove on the reciprocating screw one causes the rake to move back and forth, repeatedly raking the agricultural products in the loading box. This ensures the agricultural products are evenly turned over, increasing the contact area between the agricultural products and the air, resulting in better drying and more even heating. The loading box is fixedly connected to the inner wall of the dryer body. The roller is movably connected to the top of the loading box. The fixed rod is rotatably connected to the inner wall of the rake. The cam one is fixedly connected to the circumferential surface of the fixed rod. The fixed support plate is fixedly connected to the right side of the rake. The rotating rod... The material feeding plate is fixedly connected to the surface of the fixed support plate. The material feeding plate is rotatably connected to the circumferential surface of the rotating rod. The circular block is fixedly connected to the top of the material feeding plate. The material feeding rod is fixedly connected to the front and rear sides of the material feeding plate. A pulley assembly is driven by the output end of a motor. A reciprocating screw is rotatably connected to the inner wall of the dryer body. The pulley assembly is driven by the circumferential surface of the reciprocating screw. The circumferential surface of the roller is in contact with the inner wall of the dryer body. The circumferential surface of the cam is in contact with the circumferential surface of the circular block. The circumferential surface of the reciprocating screw is rotatably connected to the inner wall of the dryer body. The circumferential surface of the cam is in contact with the inner wall of the material feeding rake. The front and rear sides of the material feeding rake... The material rake moves back and forth between the inner wall of the feeding box and the inner wall, which in turn drives the roller to move left and right on the feeding box. When the roller moves left and right, it rotates and drives the fixed rod to rotate. When the fixed rod rotates, it drives the cam to rotate. When the cam rotates, it contacts the round block. The fixed support plate limits the movement of the round block and drives it to swing left and right. The swinging of the round block drives the material-pulling plate to swing left and right. The swinging of the material-pulling plate drives the material-pulling rod to swing left and right. The swinging of the material-pulling plate evenly moves the agricultural products, so that they can be better moved by the material rake and be dried more evenly inside the dryer. This prevents uneven heating, so that some agricultural products are not scorched while others are not completely dried.

[0007] Preferably, the scraping device includes a condensing plate, a triangular plate, a push rod, a scraper, a hinged plate, a support column, and a water storage box. The condensing plate is fixedly connected to the inner wall of the dryer body, the support column is fixedly connected to the top of the rake, the push rod is fixedly connected to the inner wall of the dryer body, and the scraper is fixedly connected to the top of the support column. The reciprocating movement of the rake drives the support column to move left and right, which in turn drives the scraper to move left and right, which in turn drives the water storage box to move left and right. Simultaneously, the left and right movement of the scraper also drives the triangular plate to move left and right, causing the water vapor generated during the drying of agricultural products to condense below the condensing plate. The scraper then scrapes down the condensed water vapor, which falls into the water storage box for collection. The number of water storage boxes is set as follows. There are two water storage boxes, which are fixedly connected to the left and right sides of the scraper, respectively. The first hinge plate is hinged to the inner wall of the water storage box. There are two triangular plates, which are fixedly connected to the left and right sides of the scraper. The top of the triangular plate is slidably connected to the bottom of the condensing plate, and the top of the scraper is slidably connected to the bottom of the condensing plate. When the water storage box moves left and right, it drives the first hinge plate to move left and right. When the first hinge plate moves left and right, it contacts the push rod. The first hinge plate will open and close intermittently, so that the water that falls into the water storage box will be indirectly discharged and slide down the inner wall of both sides of the dryer body, preventing water from falling back onto the dried items and causing the drying effect to deteriorate. At the same time, it can appropriately cool the dryer body to prevent its internal temperature from becoming too high, which would cause the agricultural products to be scorched.

[0008] Preferably, the collection and discharge device includes a second motor, a threaded rod, a connecting block, a pressing plate, a collection box, a second hinge plate, a cam block, and a second pulley set. The second motor is fixedly connected to the rear of the dryer body, the threaded rod is fixedly connected to the output end of the second motor, and the connecting block is threadedly connected to the circumferential surface of the threaded rod. Two pressing plates are provided, and the two pressing plates are fixedly connected to the left and right sides of the connecting block. When the dryer starts, the second reciprocating screw rotates, driving the second pulley set to rotate. The first motor drives the first pulley set to rotate, which in turn drives the second reciprocating screw to rotate. The second reciprocating screw rotates, driving the second pulley set to rotate, which in turn drives the cam block to rotate. This causes the second hinge plate, hinged to the collection box, to contact the cam block, allowing it to open and close intermittently, enabling water to enter the collection box. The water is absorbed by the sponge in the collection box. Simultaneously, the second hinge plate rotates inward and squeezes the sponge, making the water distribution more even and increasing its water collection capacity. The inner wall of the collection box contacts the bottom of the squeezing plate. The second hinge plate is hinged to the inner wall of the collection box. The cam block is rotatably connected to the inner wall of the dryer body. The second pulley group is driven by the circumferential surface of the second reciprocating screw. The circumferential surface of the cam block contacts the top of the second hinge plate. The axis of the cam block is fixedly connected to the pulley of the second pulley group. The collection box contains a sponge. When the door is opened, the second motor starts and drives the threaded rod to rotate. Simultaneously, the connecting block moves back and forth through the spiral groove of the threaded rod. The back and forth movement of the connecting block drives the squeezing plate to move back and forth, squeezing the sponge and discharging the water from the hole at the front of the collection box for easy reuse.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This sterilizing and disinfecting air-source heat pump dryer operates through the coordinated movement of a motor, a reciprocating lead screw, a feeding rake, rollers, a cam, a circular block, a feeding plate, a fixed support plate, a feeding rod, a pulley assembly, a reciprocating lead screw, a loading box, a fixed rod, and a rotating rod. When the dryer starts, the motor drives the reciprocating lead screw to rotate. The cross-shaped spiral groove on the reciprocating lead screw causes the feeding rake to move back and forth, repeatedly ruffling the agricultural products in the loading box. This ensures the products are evenly turned over, increasing the contact area between the products and the air, resulting in better drying and more even heating. The material rake moves back and forth, simultaneously driving the rollers to move left and right on the material box. As the rollers move left and right, they rotate, causing the fixed rod to rotate. This rotation of the fixed rod then causes the cam to rotate, contacting the circular block. Through the limiting action of the fixed support plate, the circular block swings left and right. This swinging motion of the circular block causes the material-pushing plate to swing left and right, which in turn causes the material-pushing rod to swing left and right. The swaying of the material-pushing plate evenly moves the agricultural products, ensuring they are better and more evenly moved by the material rake. This results in more uniform drying within the dryer, preventing uneven heating and ensuring some products are not scorched while others are not fully dried.

[0011] 2. This sterilizing and disinfecting air-source heat pump dryer operates through the coordinated operation of a condenser plate, triangular plate, push rod, scraper, hinge plate 1, support column, and water storage box. The reciprocating movement of the material rake drives the support column to move left and right, which in turn drives the scraper to move left and right, which in turn drives the water storage box. Simultaneously, the scraper's movement also drives the triangular plate to move left and right. This causes the water vapor generated during the drying of agricultural products to condense below the condenser plate. The scraper then scrapes off the condensed water vapor, collecting it in the water storage box. The movement of the water storage box also drives the hinge plate 1 to move left and right. When the hinge plate 1 moves left and right, it contacts the push rod, causing it to open and close intermittently. This allows water that has fallen into the water storage box to be indirectly discharged and slide down the inner walls of both sides of the dryer body, preventing water from falling back onto the dried goods and reducing the drying effect. It also helps to appropriately cool the dryer body, preventing excessive internal temperature from scorching the agricultural products.

[0012] 3. This sterilizing and disinfecting air-source heat pump dryer operates through the coordinated movement of a motor, a threaded rod, a connecting block, a pressing plate, a collection box, a hinged plate, a cam block, and a pulley assembly. When the dryer starts, the reciprocating screw rotates, driving the pulley assembly to rotate. The motor then drives the pulley assembly to rotate, which in turn drives the reciprocating screw to rotate. This rotation of the reciprocating screw drives the pulley assembly to rotate, which in turn drives the cam block to rotate. This causes the hinged plate, which is hinged to the collection box, to contact the cam block, allowing it to open and close intermittently. This allows water to enter the collection box and be absorbed by the sponge. Simultaneously, the hinged plate rotates inward and squeezes the sponge, resulting in a more even distribution of moisture and increased water collection. When the door is opened, the motor starts and drives the threaded rod to rotate. At the same time, the connecting block moves back and forth through the spiral groove of the threaded rod. This movement of the connecting block drives the pressing plate to move back and forth, causing the pressing plate to squeeze the sponge and discharge water from the hole in front of the collection box for future use.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-10One embodiment of the present invention is: an air-source heat pump dryer capable of sterilization and disinfection, comprising a dryer body 1, a material feeding device 2, a water scraping device 3, and a collection and discharge device 4, the inner wall of the dryer body 1 being provided with a material feeding device 2, the inner wall of the dryer body 1 being provided with a water scraping device 3, and the inner wall of the dryer body 1 being provided with a collection and discharge device 4; the material feeding device 2 includes a motor 201, a reciprocating lead screw 202, a material feeding rake 203, a roller 204, a cam 205, a round block 206, a material feeding plate 207, a fixed support plate 208, a material feeding rod 209, a pulley set 210, a reciprocating lead screw 211, and a material loading box 212. The dryer consists of a fixed rod 213, a rotating rod 214, and a motor 201 fixedly connected to the right side of the dryer body 1. A reciprocating screw 202 is fixedly connected to the output end of the motor 201, and a rake 203 is threadedly connected to the circumferential surface of the reciprocating screw 202. When the sterilizable air-source dryer is started, the motor 201 drives the reciprocating screw 202 to rotate. The cross-shaped spiral groove on the reciprocating screw 202 causes the rake 203 to move back and forth, repeatedly raking the agricultural products in the loading box 212, ensuring that the agricultural products in the loading box 212 are evenly distributed. The even back-and-forth turning increases the contact area between agricultural products and air, resulting in better drying and more uniform heating. The loading box 212 is fixedly connected to the inner wall of the dryer body 1. Rollers 204 are movably connected to the top of the loading box 212. A fixed rod 213 is rotatably connected to the inner wall of the feeding rake 203. A cam 205 is fixedly connected to the circumferential surface of the fixed rod 213. A fixed support plate 208 is fixedly connected to the right side of the feeding rake 203. A rotating rod 214 is fixedly connected to the surface of the fixed support plate 208. A feeding plate 207 is rotatably connected to the circumferential surface of the rotating rod 214. Block 206 is fixedly connected to the top of the feeding plate 207, feeding rod 209 is fixedly connected to the front and rear sides of the feeding plate 207, pulley group 210 is driven to the output end of motor 201, and reciprocating screw 211 is rotatably connected to the inner wall of the dryer body 1; pulley group 210 is driven to the circumferential surface of reciprocating screw 211, the circumferential surface of roller 204 is in contact with the inner wall of the dryer body 1; the circumferential surface of cam 205 is in contact with the circumferential surface of block 206, and the circumferential surface of reciprocating screw 202 is rotatably connected to the inner wall of the dryer body 1.The circumferential surface of cam 205 contacts the inner wall of the rake 203, and the front and rear sides of the rake 203 contact the inner wall of the loading box 212. This causes the rake 203 to move back and forth, simultaneously driving the roller 204 to move left and right on the loading box 212. The rotation of the roller 204 rotates the fixed rod 213, which in turn rotates the cam 205. When the cam 205 rotates, it contacts the round block 206. The fixed support plate 208 limits the movement of the round block 206, causing it to swing left and right. This swinging motion of the round block 206 causes the feeding plate 207 to swing left and right, which in turn causes the feeding rod 209 to swing left and right. The swinging motion of the feeding plate 207 evenly moves the agricultural products, allowing them to be better and more evenly moved by the rake 203, resulting in more uniform drying inside the dryer. This prevents uneven heating, ensuring some agricultural products are not scorched while others are not completely dried.

[0026] The scraping device 3 includes a condensing plate 301, a triangular plate 302, a push rod 303, a scraper 304, a hinge plate 305, a support column 306, and a water storage box 307. The condensing plate 301 is fixedly connected to the inner wall of the dryer body 1, the support column 306 is fixedly connected to the top of the feeding rake 203, the push rod 303 is fixedly connected to the inner wall of the dryer body 1, and the scraper 304 is fixedly connected to the top of the support column 306. The scraper 304 is driven by the reciprocating movement of the feeding rake 203. The support column 306 moves left and right, which in turn moves the scraper 304 left and right. This movement of the scraper 304 in turn moves the water storage box 307 left and right. Simultaneously, the scraper 304 also moves the triangular plate 302 left and right, causing the water vapor generated during the drying of agricultural products to condense below the condenser plate 301. The scraper 304 then scrapes down the condensed water vapor, which falls into the water storage box 307 for collection. Two water collection boxes 307 are provided, and the two water collection boxes 307 are fixedly connected to the left and right sides of the scraper 304 respectively. The hinge plate 305 is hinged to the inner wall of the water collection box 307. Two triangular plates 302 are provided, and the two triangular plates 302 are fixedly connected to the left and right sides of the scraper 304. The top of the triangular plate 302 is slidably connected to the bottom of the condenser plate 301, and the top of the scraper 304 is slidably connected to the bottom of the condenser plate 301. At the same time, when the water collection box 307 moves left and right, it drives the hinge plate 305 to move left and right. When the hinge plate 305 moves left and right, it contacts the push rod 303. The hinge plate 305 will open and close intermittently, so that the water that falls into the water collection box 307 will be indirectly discharged and slide down the inner walls of both sides of the dryer body 1, preventing water from falling back onto the dried items and causing the drying effect to deteriorate. At the same time, it can appropriately cool the dryer body 1 to prevent its internal temperature from becoming too high, which would cause the agricultural products to be scorched.

[0027] Working Principle: When the sterilizing air-source heat pump dryer starts, motor 201 drives reciprocating screw 202 to rotate. The cross-shaped spiral groove on the reciprocating screw 202 causes the rake 203 to move back and forth, repeatedly raking the agricultural products in the loading box 212. This ensures the agricultural products are evenly turned over, increasing the contact area between the products and the air, resulting in better drying and more even heating. Simultaneously, the reciprocating movement of the rake 203 drives the roller 204 to move left and right on the loading box 212. The rotation of the roller 204, as it moves left and right, causes the fixed rod 213 to rotate, thus... When the fixed rod 213 rotates, it drives the cam 205 to rotate. When the cam 205 rotates, it contacts the round block 206. Through the fixed support plate 208, the round block 206 swings left and right. The left and right swing of the round block 206 drives the material feeding plate 207 to swing left and right. The left and right swing of the material feeding plate 207 drives the material feeding rod 209 to swing left and right. The left and right swing of the material feeding plate 207 makes the agricultural products swing evenly, so that they can be better moved by the material feeding rake 203 and be moved more evenly. This makes them dry more evenly inside the dryer, preventing uneven heating and some agricultural products from being scorched while others are not completely dried.

[0028] The reciprocating movement of the rake 203 drives the support column 306 to move left and right. This movement of the support column 306, in turn, drives the scraper 304 to move left and right, which in turn drives the water storage box 307 to move left and right. Simultaneously, the scraper 304 also drives the triangular plate 302 to move left and right, causing the water vapor generated during the drying of agricultural products to condense below the condensing plate 301. The scraper 304 scrapes down the condensed water vapor, which falls into the water storage box 307 for collection. Simultaneously, the movement of the water storage box 307 drives the hinge plate 305 to move left and right. When the hinge plate 305 moves left and right, it contacts the push rod 303, causing it to open and close intermittently. This allows the water that has fallen into the water storage box 307 to be indirectly discharged and slide down the inner walls on both sides of the dryer body 1, preventing water from falling back onto the dried goods and reducing the drying effect. This also allows for appropriate cooling of the dryer body 1, preventing excessive internal temperature and thus avoiding scorching of the agricultural products.

[0029] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the collection and discharge device 4 includes a second motor 401, a threaded rod 402, a connecting block 403, a pressing plate 404, a collection box 405, a second hinge plate 406, a cam block 407, and a second pulley set 408. The second motor 401 is fixedly connected to the rear of the dryer body 1, the threaded rod 402 is fixedly connected to the output end of the second motor 401, the connecting block 403 is threadedly connected to the circumferential surface of the threaded rod 402, and two pressing plates 404 are provided. Furthermore, the two extrusion plates 404 are fixedly connected to the left and right sides of the connecting block 403. When the dryer starts, the reciprocating screw 211 rotates, driving the pulley assembly 408 to rotate. The motor 201 drives the pulley assembly 210 to rotate, which in turn drives the reciprocating screw 211 to rotate. The reciprocating screw 211 then drives the pulley assembly 408 to rotate, which in turn drives the cam block 407 to rotate. This causes the hinge plate 406, which is hinged to the collection box 405, to engage with the cam block 407. 7. Contact allows for intermittent opening and closing, enabling water to enter the collection box 405 and be absorbed by the sponge. Simultaneously, the hinge plate 406 rotates inward and squeezes the sponge, resulting in a more even distribution of water within the sponge and increasing its water collection capacity. The inner wall of the collection box 405 contacts the bottom of the squeezing plate 404. The hinge plate 406 is hinged to the inner wall of the collection box 405. The cam block 407 is rotatably connected to the inner wall of the dryer body 1. The pulley assembly 408 is driven by the circumferential surface of the reciprocating screw 211. The cam block 407... The circumferential surface contacts the top of the hinge plate 406. The axis of the cam block 407 is fixedly connected to the pulley of the pulley assembly 408. The inside of the collection box 405 is filled with sponge. When the door is opened, the motor 401 starts and drives the threaded rod 402 to rotate. At the same time, the connecting block 403 moves back and forth through the spiral groove of the threaded rod 402. The back and forth movement of the connecting block 403 drives the squeezing plate 404 to move back and forth, so that the squeezing plate 404 squeezes the sponge and discharges water from the hole in front of the collection box 405 for easy use next time.

[0030] Working principle: When the dryer starts, the reciprocating screw 211 rotates, driving the pulley assembly 408 to rotate. Motor 201 drives the pulley assembly 210 to rotate, which in turn drives the reciprocating screw 211, which in turn drives the pulley assembly 408. The rotation of the pulley assembly 408 then drives the cam block 407 to rotate, causing the hinge plate 406, which is hinged to the collection box 405, to contact the cam block 407, allowing it to open and close intermittently, allowing water to flow freely. The water can enter the collection box 405 and be absorbed by the sponge. At the same time, the hinge plate 406 rotates inward and squeezes the sponge, making the water distribution in the sponge more even and increasing its water collection capacity. When the door is opened, the motor 401 starts and drives the threaded rod 402 to rotate. At the same time, the connecting block 403 moves back and forth through the spiral groove of the threaded rod 402. The back and forth movement of the connecting block 403 drives the squeezing plate 404 to move back and forth, so that the squeezing plate 404 squeezes the sponge and discharges the water from the hole in front of the collection box 405 for easy use next time.
