Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to a pipeline heat preservation and heating device for water environmental protection equipment. Background Art

[0002] The pipelines in environmental protection equipment are mainly used to transport liquids or gases to achieve the normal operation of environmental protection equipment. Environmental protection equipment may require liquids or gases to have a higher temperature accuracy during normal operation. Therefore, heating equipment may be required on some pipelines to ensure that the liquid or gas in the pipeline has a reasonable temperature.

[0003] Existing pipeline heating devices are mainly used to prevent the water flow in the pipeline from freezing in a low temperature environment to ensure the normal operation of environmental protection equipment. The heating device heats the water flow in the pipeline and circulates it to avoid the problem of pipeline freezing caused by low temperature. However, in actual applications, in order to reduce costs and improve operational convenience, groundwater or river water is usually directly extracted as a water source. These water sources contain a lot of impurities, such as silt, minerals, etc., and the impurities will enter the heating pipeline during the extraction process. If these impurities cannot be discharged in time, they will gradually accumulate on the inner wall of the heating pipeline to form a layer of sediment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention arranges an interception component and a detection component. On the one hand, the first interception net can effectively block large particles of impurities, which helps to reduce the pressure of subsequent filter components and prevent the problem of poor water flow due to excessive accumulation of impurities. The graded interception system allows larger impurities to be intercepted in the first layer, while smaller particles are further processed in the second layer, thereby improving the overall interception effect and the reliability of the system. On the second hand, the graded interception reduces the burden of a single filter component and reduces its clogging speed, thereby extending the maintenance cycle of the system and reducing the cleaning frequency and maintenance cost. On the third hand, the rotating action of the interception component not only helps to intercept impurities, but also disturbs the water flow, making the impurities more evenly distributed, which is conducive to avoiding local accumulation, further ensuring the smoothness of the water flow, and facilitating subsequent discharge.

[0017] 2. The present invention sets a sewage outlet and drives the piston disc to move downward along the sewage barrel through the second electric push rod. The piston disc drives the sealing ring to move along the inner wall of the sewage barrel, and the outer wall of the piston disc is sealed by the sealing ring to prevent moisture from entering the bottom space of the piston disc. As the piston disc and the sealing ring move downward, the water above the piston disc will flow downward with the piston disc, and because of the setting of the second baffle plate, the exposure time of the sealing ring and the piston disc will be prolonged when the sewage outlet moves downward. When the second baffle plate moves downward with the sealing ring and gradually exposes the sewage outlet, the suction force generated by the piston disc will also adsorb the impurities at the second interception point, so that they can enter the interior of the sewage barrel and then be discharged outward through the sewage outlet.

[0018] 3. The present invention, through the arrangement of the first screening circular screen and the second screening circular screen, performs vibration cleaning on impurities that may stick to the second screening circular screen through the collision vibration generated between the screen and the hanging seat, thereby facilitating keeping the interception surface of the second screening circular screen clean. In the process of the second screening circular screen following the flipping of the first screening circular screen, the electric push rod is synchronously started to start the operation, and the electric push rod drives the piston circular plate to move downward. The piston circular plate generates an adsorption force when moving downward, thereby facilitating the adsorption of impurities on the second screening circular screen during the flipping process. On the one hand, it is beneficial to prevent the impurities of the second screening circular screen from moving toward the second interception net during the flipping process. On the other hand, in the process of the flipping of the second screening circular screen, the gap between the second screening circular screen and the sewage barrel becomes larger, thereby facilitating the adsorption of impurities on the second interception net.

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] Application scenarios: Existing pipe heating devices are mainly used to prevent the freezing of water in pipes in low temperature environments and ensure the normal operation of environmental protection equipment. The heating device heats the water in the pipe and circulates it to avoid the problem of pipe freezing caused by low temperature. However, in actual applications, in order to reduce costs and improve operational convenience, groundwater or river water is usually directly extracted as a water source. These water sources contain a lot of impurities, such as silt, minerals, etc., and the impurities will enter the heating pipe during the extraction process. If these impurities cannot be discharged in time, they will gradually accumulate on the inner wall of the heating pipe to form a layer of sediment. This will not only reduce the efficiency of heat conduction and affect the heating effect, but may also cause local overheating and increase the risk of equipment damage.

[0029] like Figures 1 to 7 The water environmental protection equipment pipeline insulation and heating device shown in the figure includes a water pumping circulation component, a circulation pipe 1, a heating pipe 2 and a connecting pipe 3. The water pumping circulation component is used to draw water from the circulation pipe 1 to the inside of the circulation pipe 1, the heating pipe 2 is fixedly connected to the circulation pipe 1, the connecting pipe 3 is fixedly connected to the heating pipe 2, and the connecting pipe 3 is used to transport the heated hot water to each heating pipe. The water pumping circulation component includes a mounting seat 4, on which a circulating water pump 5 is fixedly installed, the water inlet end of the circulating water pump 5 is fixedly connected to a pumping member, the water outlet end of the circulating water pump 5 is fixedly connected to an outlet pipe 6, and the outlet pipe 6 is fixedly connected to the circulation pipe 1.

[0030] As a further implementation scheme of the present invention, a first interception net 7 is fixedly connected to the inside of the circulation pipe 1, and a rotating cylinder 8 is rotatably connected to one side of the first interception net 7. A first blade 9 is fixedly connected to the outer wall of the rotating cylinder 8. An interception component is provided at one end of the rotating cylinder 8 away from the first interception net 7. The interception component is used for secondary interception of impurities passing through the first interception net 7, and a detection component is provided on the side of the first interception net 7 away from the interception component.

[0031] Embodiment 1: During operation, after the circulating water pump 5 is started, the water pump will draw water from the target area and introduce it into the circulating pipe 1. Subsequently, the water is transported to the heating pipe 2 through the circulating pipe 1. Inside the heating pipe 2, the water is heated by the heating element and the temperature rises. The heated hot water is then distributed to each heating pipe through the connecting pipe 3, thereby heating the target pipe to ensure that it does not freeze or maintain the required temperature in a low temperature environment. This process not only realizes the recycling of water, but also effectively improves the overall heating efficiency and stability of the system. This can help ensure that the medium in the target pipe always maintains fluidity and a suitable operating temperature;

[0032] In the process of water passing through the circulation pipe 1, the first interception net 7 will first intercept the larger impurities in the water source. The pre-set aperture of the first interception net 7 can ensure that the larger impurities are effectively intercepted, while smaller particles can pass through the net. In this process, the water flow impacts the first blade 9, prompting the first blade 9 to rotate. The rotation of the first blade 9 drives the entire interception component to rotate, further intercepting the impurities passing through the first interception net 7, which is beneficial to prevent them from entering the heating tube 2 and accumulating. Compared with the traditional single interception method, this design adopts a two-layer graded interception system, which has at least the following advantages: First, the first interception net 7 can effectively block large particles of impurities, which helps to reduce the pressure of subsequent filtering components. It is helpful to prevent the problem of poor water flow caused by excessive accumulation of impurities. The graded interception system allows larger impurities to be intercepted in the first layer, while smaller particles are further processed in the second layer, thereby improving the overall interception effect and system reliability. Secondly, the graded interception reduces the burden on a single filter component and reduces its clogging speed, thereby extending the system maintenance cycle, reducing the cleaning frequency and maintenance costs. Thirdly, the rotating action of the interception component not only helps to intercept impurities, but also disturbs the water flow, making the impurities more evenly distributed, which is helpful to avoid local accumulation, further ensuring the smoothness of the water flow, and facilitating subsequent discharge, thereby preventing impurities from entering different pipes and accumulating.

[0033] It should be noted that the pumping parts are existing technologies, including existing components such as pumping pipes, and will not be disclosed in detail here.

[0034] As a further embodiment of the present invention, the interception assembly includes a fixed disk 10, which is fixedly connected to the inside of the rotating cylinder 8. A slide rod 11 is slidably connected to the fixed disk 10. A spring 12 is fixedly connected between the fixed disk 10 and the rotating cylinder 8. The spring 12 is sleeved on the outer wall of the slide rod 11. An end of the slide rod 11 away from the first blade 9 is fixedly connected to a support rod 13, and an end of the support rod 13 away from the slide rod 11 is fixedly connected to a second interception net 14.

[0035] As a further implementation scheme of the present invention, the detection component includes a detection rod 15 and a discharge trough 16. The discharge trough 16 is opened on the first interception net 7. After the detection rod 15 passes through the first interception net 7, it is fixedly connected to the sliding rod 11. The detection rod 15 is slidably connected to the first interception net 7. A plurality of toggle plates 17 are fixedly connected to the outer wall of the detection rod 15 in a circular array, and the toggle plates 17 cooperate with the discharge trough 16.

[0036] It should be understood that in the process of water being drawn and flowing, the water flow will act on the second interception net 14, and the impact force generated will push the second interception net 14 to move in the direction away from the first interception net 7. If the first interception net 7 is blocked, the water flow passing through it will be reduced. Therefore, the force acting on the second interception net 14 will be reduced, so that the second interception net 14 will be pulled back to its original position under the action of the spring 12. When the second interception net 14 returns to its original position, it will push the support rod 13 to move, the support rod 13 will push the slide bar 11 to move, and the slide bar 11 will push the detection When the rod 15 moves, the detection rod 15 will push the toggle plate 17 to slide out from the inside of the discharge groove 16. At this time, if the first blade 9 still cannot rotate, it means that the blockage occurs at the second interception net 14, and if after the toggle plate 17 slides out from the inside of the discharge groove 16, a new through hole will appear, and the new through hole is set to be larger than the filter hole of the first interception net 7. Therefore, some impurities blocked at the first interception net 7 will pass through the new through hole, and as the water flow increases, the first blade 9 can rotate, indicating that the blockage occurs at the first interception net 7.

[0037] As a further implementation scheme of the present invention, sliding grooves 18 are symmetrically opened on the outer wall of the rotating cylinder 8, and the interiors of the two sliding grooves 18 are slidably connected with levers 19, and a breaking plate 20 is fixedly connected to the outer wall of the lever 19. A groove 21 is opened on the sliding rod 11, and the lever 19 is located in the groove 21.

[0038] Embodiment 2: During the rotation of the rotating drum 8, the lever 19 will also be driven to rotate, and the lever 19 will drive the scattering plate 20 to rotate. The rotating action of the scattering plate 20 helps to disturb the water flow, so that impurities are more evenly distributed in the water flow, which is beneficial to avoid excessive accumulation in local areas and further ensure the smoothness of the water flow. In addition, the scattering plate 20 will scatter the impurities passing through the first interception net 7 in the process of following the rotation of the rotating drum 8, so that the impurities are further dispersed in volume, so that these impurities can be more evenly dispersed, which is beneficial to reduce the possibility of the second interception net 14 being blocked by large impurities. Combined with Embodiment 1, since the impurities are further dispersed and evenly distributed in the water flow by the rotating scattering plate 20 after passing through the first interception net 7, it is beneficial to avoid excessive accumulation in local areas, thereby reducing the risk of the second interception net 14 being blocked by the accumulation of large impurities. The rotating movement of the second interception net 14 further enhances the treatment effect of the dispersed impurities. As the mesh surface rotates, fine impurities are more easily filtered out evenly rather than concentrated in one place, thereby greatly reducing the possibility of clogging. Since the rotation of the second interception net 14 can continuously disturb the water flow, the impurities will not stay on the mesh surface for a long time to form accumulation. This design effectively prevents the wear or damage of the second interception net 14 caused by the long-term accumulation of impurities, which is conducive to extending the service life of the equipment.

[0039] Furthermore, as new larger impurities enter the space where the first blade 9 is located, the scattering plate 20 will further disperse the impurities and cooperate with the rotation of the second interception net 14, which is helpful to prevent the first interception net 7 from being blocked and causing the pipeline to be blocked.

[0040] As a further implementation scheme of the present invention, the bottom of the circulation pipe 1 is fixedly connected to a sewage cylinder 22, and two sewage outlets 23 are provided on the side wall of the sewage cylinder 22. A sealing gasket 24 is fixedly connected to the inside of the sewage cylinder 22, and an electric push rod 25 is fixedly connected to the bottom of the sewage cylinder 22 through a mounting frame. The telescopic end of the electric push rod 25 passes through the sewage cylinder 22 and is fixedly connected to a piston disk 26. The sealing gasket 24 is slidably connected to the telescopic end of the electric push rod 25, and a sealing ring 27 is fixedly installed on the outer wall of the piston disk 26, and the sealing ring 27 conflicts with the inner wall of the sewage cylinder 22.

[0041] As a further implementation scheme of the present invention, two first baffles 28 are fixedly connected to the top of the sealing ring 27, and two second baffles 29 are fixedly connected to the bottom of the sealing ring 27. In the initial state, the first baffles 28 block the sewage outlet 23, and the second baffles 29 are used to extend the leakage time of the sewage outlet 23.

[0042] Embodiment 3. In the above embodiment, it is explained that the first interception net 7 and the second interception net 14 are used to intercept the impurities separately, and the impurities passing through the first interception net 7 are further dispersed by the scattering plate 20, so as to finally reduce the accumulation of impurities on the second interception net 14. However, although the above measures can extend the service life of the second interception net 14 to a certain extent, during long-term use, the impurities accumulated on the second interception net 14 will increase, and it is difficult to avoid clogging by relying on the rotation of the second interception net 14 itself. Therefore, a sewage discharge barrel 22 is provided to solve the problem. After the preset time is reached, the electric push rod 25 is controlled to start working, and the second electric push rod 25 drives the piston disc 26 to move downward along the sewage discharge barrel 22. The piston disc 26 drives the sealing ring 27 to move along the inner wall of the sewage barrel 22, and the sealing ring 27 seals the outer wall of the piston disc 26 to prevent moisture from entering the bottom space of the piston disc 26. As the piston disc 26 and the sealing ring 27 move downward, the water above the piston disc 26 will flow downward with the piston disc 26, and because of the setting of the second shielding plate 29, the time for the sealing ring 27 and the piston disc 26 to be exposed to the sewage outlet 23 will be prolonged when the second shielding plate 29 moves downward with the sealing ring 27 and makes the sewage outlet 23 gradually exposed, the suction force generated by the piston disc 26 will also absorb the impurities at the second interception point, so that they can enter the interior of the sewage barrel 22 and then be discharged outward through the sewage outlet 23.

[0043] Combined with the first and second embodiments, by determining which interception net the blockage occurs on, it is decided whether to start the sewage discharge in advance. For example, when it is determined that the blockage occurs at the second interception location, the predetermined start time has not yet arrived. In order to prevent the use from being affected, it is necessary to start the sewage discharge in advance and perform the above operations in advance. In addition, when the second interception net 14 is pulled back under the action of the spring 12, the second interception net 14 will move toward the sewage discharge barrel 22, which is conducive to moving the impurities attached to the interception, thereby facilitating the cleaning of the impurities attached to the surface of the second interception net 14 and reducing the residues on the interception.

[0044] As a further embodiment of the present invention, an annular heating plate 30 is provided at the bottom of the sewage barrel 22 , and the annular heating plate 30 is used to heat and evaporate the moisture in the space below the sealing ring 27 inside the sewage barrel 22 .

[0045] In the fourth embodiment, when the piston disc 26 moves downward to discharge sewage from the sewage outlet 23, moisture will leak into the part above the sealing ring 27. Then, when the sealing ring 27 moves upward, the residual moisture will be cleaned up in the first step. By setting the annular heating plate 30 to heat the inside of the sewage barrel 22, the residual moisture in the bottom space of the piston disc 26 will be evaporated, and the residual moisture will be cleaned up in the second step, which is beneficial to maintain the dryness of the inside of the sewage barrel 22 and reduce corrosion to the sewage barrel 22.

[0046] As a further implementation scheme of the present invention, a first screening circular screen 31 is rotatably connected inside the sewage barrel 22, and a motor 32 is fixedly connected to the outer wall of the first screening circular screen 31. The motor 32 is fixedly installed on the outer wall of the sewage barrel 22, and a hanging rod 33 is rotatably connected to the first screening circular screen 31. The end of the hanging rod 33 away from the piston disk 26 is fixedly connected to a hanging seat 34, and a second screening circular screen 35 is slidably connected to the outer wall of the hanging rod 33. The sieve holes of the first screening circular screen 31 and the second screening circular screen 35 are staggered.

[0047] As a further embodiment of the present invention, a second blade 36 is fixedly connected to one end of the hanging rod 33 away from the hanging seat 34, and two scraping rods 37 are symmetrically fixedly connected to the outer wall of the hanging seat 34. Scrapers 38 are fixedly connected to the outer walls of the two scraping rods 37, and the scrapers 38 are inclined.

[0048] Embodiment 5: In the initial state, the water flowing toward the sewage barrel 22 is intercepted by setting the first sieve circular screen 31 and the second sieve circular screen 35, and the sieve holes of the first sieve circular screen 31 and the second sieve circular screen 35 are staggered, so that the water flow cannot flow into the sewage barrel 22 through the first sieve circular screen 31 and the second sieve circular screen 35, which is helpful to prevent the water flow from entering the sewage barrel 22 when it is not necessary. Before the electric push rod 25 starts working, the motor 32 is first controlled to start working, and the motor 32 drives the first sieve circular screen 31 to rotate 180 degrees, and the first sieve circular screen The second screening circular screen 35 is driven to rotate 180 degrees by the hanging rod 33, so that the second blade 36 is located above the first screening circular screen 31. Because, at this time, the second screening circular screen 35 is rotated 180 degrees and the impurity intercepting side faces downward, and under the action of gravity, the second screening circular screen 35 slides downward on the hanging rod 33, so that the intercepting side of the second screening circular screen 35 contacts the hanging seat 34, and the impurities that may be attached to the second screening circular screen 35 are vibrated and cleaned by the collision vibration generated between the hanging seat 34, so as to help keep the intercepting side of the second screening circular screen 35 clean.

[0049] Furthermore, in the process of the second screening circular screen 35 following the first screening circular screen 31 turning over, the electric push rod 25 is synchronously started to start working, and the electric push rod 25 drives the piston circular plate to move downward, and the piston circular plate generates an adsorption force when moving downward, which is conducive to adsorbing impurities on the second screening circular screen 35 during the turning process. On the one hand, it is conducive to preventing the impurities of the second screening circular screen 35 from moving toward the second interception net 14 during the turning process. On the other hand, in the process of the second screening circular screen 35 turning over, the gap between the second screening circular screen 35 and the sewage barrel 22 becomes larger, which is conducive to adsorbing impurities on the second interception net 14.

[0050] After the second blade 36 flips 180 degrees, as the piston circular plate generates adsorption force on the water flow, the second blade 36 rotates under the action of the water flow, and the second blade 36 drives the hanging rod 33 to rotate, the hanging rod 33 drives the hanging seat 34 to rotate, the hanging seat 34 drives the scraper rod 37 to rotate, and the scraper rod 37 drives the scraper plate 38 to rotate, so that the scraper plate 38 can assist in cleaning impurities from the second screening circular screen 35, thereby cooperating with the adsorption force generated by the piston circular plate to further clean the impurities remaining on the second screening circular screen 35;

[0051] Furthermore, as the second intercepting net 14 pushes the support rod 13 to move, the support rod 13 pushes the slide rod 11 to move. During the movement of the slide rod 11, the groove 21 will contact the lever 19 and push the lever 19 to move. The movement of the lever 19 will drive the scattering plate 20 to move, so that the scattering plate 20 will move in the direction away from the first screening circular screen 31, and will not affect the subsequent flipping of the first screening circular screen 31 and the second screening circular screen 35.

[0052] Working principle of the present invention:

[0053] During operation, after the circulating water pump 5 is started, the water pump will draw water from the target area and introduce it into the circulating pipe 1. Subsequently, the water is transported to the heating pipe 2 through the circulating pipe 1. Inside the heating pipe 2, the water is heated by the heating element and the temperature rises. The heated hot water is then distributed to each heating pipe through the connecting pipe 3, thereby heating the target pipe to ensure that it will not freeze or maintain the required temperature in a low temperature environment. This process not only realizes the recycling of water, but also effectively improves the overall heating efficiency and stability of the system. This ensures that the medium in the target pipe always maintains fluidity and a suitable working temperature;

[0054] When water passes through the circulation pipe 1, the first interception net 7 will first intercept larger impurities in the water source. The pre-set aperture of the first interception net 7 can ensure that larger impurities are effectively intercepted, while smaller particles can pass through the net. In this process, the water flow impacts the first blade 9, prompting the first blade 9 to rotate. The rotation of the first blade 9 drives the entire interception assembly to rotate, further intercepting the impurities passing through the first interception net 7, which is conducive to preventing them from entering the heating tube 2 and accumulating. Compared with the traditional single interception method, this design adopts a two-layer hierarchical interception system, which has at least the following advantages: First, the first interception net 7 can effectively block large impurities. Particulate impurities help reduce the pressure on subsequent filter components and prevent problems such as poor water flow caused by excessive accumulation of impurities. The graded interception system allows larger impurities to be intercepted in the first layer, while smaller particles are further processed in the second layer, improving the overall interception effect and system reliability. Secondly, the graded interception reduces the burden on individual filter components and reduces their clogging speed, thereby extending the system's maintenance cycle and reducing cleaning frequency and maintenance costs. Thirdly, the rotating action of the interception component not only helps to intercept impurities, but also disturbs the water flow, making impurities more evenly distributed, which helps to avoid local accumulation and further ensures the smoothness of water flow.
