Abstract

The present invention discloses a water-cooled screw ultra-high temperature heat pump unit, whose structure includes a control box, a water pump, and an exchanger. The lower side of the control box is welded to the upper side of the exchanger, and the lower side of the water pump is welded to the upper side of the exchanger. The exchanger includes a support frame, an exchange cylinder, a water outlet pipe, and an access pipe. The upper end of the support frame is fixedly connected to the outside of the exchange cylinder. The water flow impacts the scraping wall device, causing the fan blades fixed by the fixed frame of the rotating head to rotate. During the rotation process, the threaded wire rotates accordingly, scraping the inner wall of the straight pipe wall to prevent the dissolved carbonate from adhering to the inner side of the straight pipe wall by the cooled wastewater.

Description

Technical Field

[0001] The present invention belongs to the technical field of high-temperature heat pumps, and more specifically, particularly relates to a water-cooled screw ultra-high temperature heat pump unit. Background Art

[0002] A high-temperature heat pump is a device for industrial enterprises to recover and utilize the heat generated during production. The device collects the heat generated during the production process, and after collection, the heat is exchanged through a pipeline between the waste gas or wastewater and clean water source in a heat exchanger. The heat exchange pipeline is installed in a spiral shape in the heat exchanger. However, wastewater usually contains a large amount of carbonate. The solubility of carbonate is high at high temperatures and low at low temperatures. When the temperature of the wastewater in the pipeline is absorbed by pure water, the solubility of carbonate in the wastewater decreases, causing the carbonate to precipitate and then adhere to the upper side of the pipeline wall, reducing the heat conduction capacity of the pipeline wall. At the same time, the internal diameter of the pipeline is reduced, resulting in a decrease in the heat conversion efficiency of the heat pump unit, and even a risk of pipeline rupture due to excessive pressure caused by pipeline blockage. Summary of the Invention

[0003] In order to solve the above technical problems that wastewater usually contains a large amount of carbonate, the solubility of carbonate is high at high temperatures and low at low temperatures. When the temperature of the wastewater in the pipeline is absorbed by pure water, the solubility of carbonate in the wastewater decreases, causing the carbonate to precipitate and then adhere to the upper side of the pipeline wall, reducing the heat conduction capacity of the pipeline wall. At the same time, the internal diameter of the pipeline is reduced, resulting in a decrease in the heat conversion efficiency of the heat pump unit, and even a risk of pipeline rupture due to excessive pressure caused by pipeline blockage, the present invention provides a water-cooled screw ultra-high temperature heat pump unit.

[0004] In order to achieve the above object, the present invention is realized by the following technical solution: A water-cooled screw ultra-high temperature heat pump unit, whose structure includes a control box, a water pump, and an exchanger. The lower side of the control box is welded to the upper side of the exchanger, and the lower side of the water pump is welded to the upper side of the exchanger. The exchanger includes a support frame, an exchange cylinder, a water outlet pipe, and an access pipe. The upper end of the support frame is fixedly connected to the outer side of the exchange cylinder, the left end of the water outlet pipe is fixedly connected to the right side of the exchange cylinder, and the left end of the access pipe is fixedly connected to the right side of the exchange cylinder.

[0005] As a further improvement of the present invention, the exchange cylinder includes a high-temperature pipe, a housing, and a partition. The upper end of the high-temperature pipe is fixedly connected to the upper end of the housing, the outer side of the partition is welded to the inner side of the housing, and the partition divides the housing into two parts of the same size up and down in the middle, with a partial notch left at the left end, so that clean water can flow upward from the bottom of the housing, increasing the flow rate of water inside the housing.

[0006] As a further improvement of the present invention, the high-temperature pipe includes a straight pipe wall, a wall scraper, and a threaded pipe. The left end of the straight pipe wall is welded to the left end of the threaded pipe. The outer side of the wall scraper is slidably matched with the inner side of the straight pipe wall. The length of the wall scraper is the same as the length inside the straight pipe wall, and at the same time, the width of the wall scraper is the same as the width inside the straight pipe wall, so that the wall scraper can scrape the inner side of the straight pipe wall, which is beneficial to preventing carbonate from adhering to the inner wall of the straight pipe wall.

[0007] As a further improvement of the present invention, the wall scraper includes a rotating head, a main rod, a threaded wire, and a positioning ring. The lower side of the rotating head is fixedly connected to the upper side of the main rod. The outer side of the threaded wire is riveted to the main rod. The inner side of the positioning ring is welded to the outer side of the threaded wire. The number of positioning rings is three and they are evenly distributed, so that the threaded wire can maintain the distance of the threaded wire through the positioning ring while rotating, preventing the threaded wire from winding during rotation.

[0008] As a further improvement of the present invention, the rotating head includes a fixed frame, a clamping block, and a fan blade. The outer side of the fixed frame has a clearance fit with the outer side of the clamping block. The upper and lower ends of the fan blade are movably clamped to the middle of the fixed frame. The number of clamping blocks is two and they are symmetrically distributed left and right with the fan blade as the center, so that the fixed frame can rotate under the fixation of the clamping block, which is beneficial to utilizing the power of the water flow inside the straight pipe wall.

[0009] As a further improvement of the present invention, the threaded pipe includes a heat exchange wall, a disturbing device, and a flow channel. The inner side of the heat exchange wall is riveted to the middle of the disturbing device. The outer side of the flow channel is fixedly connected to the inner side of the heat exchange wall. The disturbing device is installed in the middle of the heat exchange wall and is inclined, so that the water flow will impact the disturbing device when flowing inside the heat exchange wall, increasing the movement range of the disturbing device.

[0010] As a further improvement of the present invention, the disturbing device includes a deflecting head, a pulling wire, a floating ball, and a swinging ball. The outer side of the deflecting head is fixedly connected to the bottom of the pulling wire. The outer side of the floating ball is welded to the outer side of the pulling wire. The outer side of the swinging ball is welded to the lower end of the pulling wire. The inside of the floating ball is a hollow structure and the external structure is the same as that of the swinging ball, so that the floating ball can maintain its position through the internal hollow structure, preventing the floating ball from flowing upward under the impact of the water flow and preventing the pulling wire from winding.

[0011] As a further improvement of the present invention, the swinging ball includes a fixed ball, a resilient block, a ball wall, and scraping wires. The outer side of the fixed ball is fixedly connected to the bottom of the resilient block. The middle of the ball wall is in clearance fit with the outer side of the scraping wires. The bottom of the scraping wires is welded to the outer side of the resilient block. The number of scraping wires is twenty-four and they are annularly distributed around the fixed ball, so that the scraping wires can scrape the heat exchange wall during the swinging of the agitator, which helps prevent carbonates from staying on the inner side of the heat exchange wall and improves the heat exchange efficiency of the heat exchange wall. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The water flow impacts the scraping wall device, causing the fan blades fixed by the fixed frame of the rotating head to rotate. During the rotation, the threaded wires rotate accordingly to scrape the inside of the straight pipe wall, preventing the dissolved carbonates from adhering to the inner side of the straight pipe wall by the cooled wastewater.

[0014] The water flow continuously impacts the agitator inside the flow channel. The agitator is impacted by the water flow through the deflecting head, generating deflection and driving the floating ball and the swinging ball to swing, so that the scraping wires can disturb the carbonates attached to the inner side of the heat exchange wall, effectively preventing the carbonates from staying on the inner side of the heat exchange wall and improving the heat exchange efficiency of the heat exchange wall.

Detailed implementation mode

[0025] The following further describes the present invention with reference to the accompanying drawings: Embodiment

[0026] As shown in the attached Figure 1 to the attached Figure 6 figure:

[0027] The present invention provides a water - cooled screw ultra - high - temperature heat pump, and its structure includes a control box 1, a water pump 2, and an exchanger 3. The lower side of the control box 1 is welded to the upper side of the exchanger 3, and the lower side of the water pump 2 is welded to the upper side of the exchanger 3. The exchanger 3 includes a support frame 31, an exchange cylinder 32, a water outlet pipe 33, and an access pipe 34. The upper end of the support frame 31 is fixedly connected to the outside of the exchange cylinder 32, the left end of the water outlet pipe 33 is fixedly connected to the right side of the exchange cylinder 32, and the left end of the access pipe 34 is fixedly connected to the right side of the exchange cylinder 32.

[0028] Among them, the exchange cylinder 32 includes a high - temperature pipe 321, an outer shell 322, and a partition 323. The upper end of the high - temperature pipe 321 is fixedly connected to the upper end of the outer shell 322, the outside of the partition 323 is welded to the inside of the outer shell 322, and the partition 323 divides the outer shell 322 into two parts of the same size up and down in the middle, leaving a partial notch at the left end, so that clean water can flow upward from the bottom of the outer shell 322, increasing the flow rate of water inside the outer shell 322.

[0029] Among them, the high - temperature pipe 321 includes a straight pipe wall 21a, a scraping device 21b, and a threaded pipe 21c. The left end of the straight pipe wall 21a is welded to the left end of the threaded pipe 21c, the outside of the scraping device 21b is slidably matched with the inside of the straight pipe wall 21a. The length of the scraping device 21b is the same as the length inside the straight pipe wall 21a, and at the same time, the width of the scraping device 21b is the same as the width inside the straight pipe wall 21b, so that the scraping device 21b can scrape the inside of the straight pipe wall 21b, which is beneficial to preventing carbonate from adhering to the inner wall of the straight pipe wall 21a.

[0030] Among them, the scraping device 21b includes a rotating head b1, a main rod b2, a threaded wire b3, and a positioning ring b4. The lower side of the rotating head b1 is fixedly connected to the upper side of the main rod b2. The outer side of the threaded wire b3 is riveted to the main rod b2. The inner side of the positioning ring b4 is welded to the outer side of the threaded wire b3. The number of the positioning rings b4 is three and they are evenly distributed, so that the threaded wire b3 can maintain the distance of the threaded wire b3 through the positioning ring b4 while rotating, preventing the threaded wire b3 from being wound during the rotation process.

[0031] Among them, the rotating head b1 includes a fixed frame b11, a clamping block b12, and a fan blade b13. The outer side of the fixed frame b11 has a clearance fit with the outer side of the clamping block b12. The upper and lower ends of the fan blade b13 are movably clamped with the middle part of the fixed frame b11. The number of the clamping blocks b12 is two and they are symmetrically distributed left and right with the fan blade b13 as the center, so that the fixed frame b11 can rotate under the fixation of the clamping block b12, which is beneficial to utilizing the power of the water flow inside the straight pipe wall 21a.

[0032] The specific usage mode and function of this embodiment:

[0033] In the present invention, the control box 1 controls the water pump 2 to introduce the wastewater in production into the exchanger 3. Under the fixation of the support frame 31, the exchange cylinder 32 introduces the unheated water through the access pipe 34, and then discharges the heated hot water through the water outlet pipe 33. After the high-temperature wastewater is introduced into the high-temperature pipe 321, the cold water inside the outer shell 322 flows back inside the outer shell 322 through the partition plate 323. The wastewater diffuses its own heat outward through the threaded pipe 21c, and the wastewater after absorbing the heat is then discharged outward through the straight pipe wall 21a. After the wastewater absorbs the heat, the carbonate contained in the wastewater will gradually precipitate. The water flow impacts the scraping device 21b, causing the fan blade b13 fixed by the fixed frame b11 of the rotating head b1 to rotate. During the rotation process, the clamping block b12 limits the fixed frame b11, driving the main rod b2 to rotate. During the rotation process, the threaded wire b3 rotates accordingly and scrapes the inside of the straight pipe wall 21a through rotation. During the scraping, the positioning ring b4 fixes the threaded wire b3 by being fixed inside the straight pipe wall 21a, preventing the threaded wire b3 from being wound during the rotation process. At the same time, the threaded wire b3 is used to scrape the inner side of the straight pipe wall 21a, preventing the dissolved carbonate from adhering to the inner side of the straight pipe wall 21a after the wastewater cools down. Embodiment

[0034] As shown in the attached Figure 7 to the attached Figure 9 figure:

[0035] Among them, the threaded tube 21c includes a heat exchange wall c1, a stirrer c2, and a flow channel c3. The inner side of the heat exchange wall c1 is riveted and connected to the middle of the stirrer c2. The outer side of the flow channel c3 is fixedly connected to the inner side of the heat exchange wall c1. The stirrer c2 is installed in the middle of the heat exchange wall c1 and is inclined, so that when the water flows inside the heat exchange wall c1, it will impact the stirrer c2, increasing the movement range of the stirrer c2.

[0036] Among them, the stirrer c2 includes a deflection head c21, a pulling wire c22, a floating ball c23, and a swinging ball c24. The outer side of the deflection head c21 is fixedly connected to the bottom of the pulling wire c22. The outer side of the floating ball c23 is welded to the outer side of the pulling wire c22. The outer side of the swinging ball c24 is welded to the lower end of the pulling wire c22. The inside of the floating ball c23 is a hollow structure, and the outer structure is the same as that of the swinging ball c24, so that the floating ball c23 can maintain its position through the internal hollow structure, preventing the floating ball from flowing upward under the impact of water flow and preventing the pulling wire c22 from winding.

[0037] Among them, the swinging ball c24 includes a fixed ball r1, a resilient block r2, a ball wall r3, and a scraping wire r4. The outer side of the fixed ball r1 is fixedly connected to the bottom of the resilient block r2. The middle of the ball wall r3 is in clearance fit with the outer side of the scraping wire r4. The bottom of the scraping wire r4 is welded to the outer side of the resilient block r2. The number of scraping wires r4 is twenty-four and they are annularly distributed around the fixed ball r1, so that the scraping wire r4 can scrape the heat exchange wall c1 during the swinging of the stirrer c2, which is beneficial to preventing carbonates from staying on the inner side of the heat exchange wall c1 and improving the heat exchange efficiency of the heat exchange wall c1.

[0038] Specific usage and functions of this embodiment:

[0039] In the present invention, when the wastewater enters the heat exchange wall c1 and the temperature drops, carbonates in the high-temperature wastewater continuously precipitate. At the same time, the water flow will continuously impact the stirrer c2 inside the flow channel c3. The stirrer c2 is impacted by the water flow through the deflection head c21 and generates deflection. The deflection drives the pulling wire c22 to swing left and right. During the swinging process, the floating ball c23 swings above the swinging ball c24 under the buoyancy of water. When swinging, it will press the scraping wire r4 against the inner side of the ball wall r3 through the resilient block r2 on the outer side of the fixed ball r1, so that the scraping wire r4 can disturb the carbonates attached to the inner side of the heat exchange wall c1, effectively preventing the carbonates from staying on the inner side of the heat exchange wall c1 and improving the heat exchange efficiency of the heat exchange wall c1.
