Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering drainage technology, and in particular relates to an integrated pump station with antifreeze and heat preservation. Background Technology

[0002] Integrated pumping stations, as a crucial component of modern urban infrastructure, are vital for ensuring the stable operation of urban drainage and water supply systems. Especially in cold regions, the anti-freezing and insulation performance of integrated pumping stations directly impacts their normal operation and lifespan. In extremely cold weather, the water inside integrated pumping stations easily freezes, causing damage to pumps, pipes, and other equipment due to frost expansion. This damage not only affects the normal operation of the equipment but can also paralyze the entire pumping station system. Currently, existing integrated pumping stations lack anti-freezing and insulation capabilities. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing an integrated pump station with antifreeze and heat preservation functions, which has excellent antifreeze and heat preservation capabilities.

[0004] In view of this, the present invention provides an integrated pump station with antifreeze and heat preservation in this embodiment, including a shell, a mounting base at the bottom of the shell, a cover plate at the top, an inlet pipe connected to the shell, a sewage pump inside the shell, a sewage pipe assembly connected to the sewage pipe assembly connected to the outlet pipe, a heating layer covering the outer wall of the shell, an insulation layer abutting against the outside of the heating layer, a temperature sensor inside the shell that can contact the inlet liquid on the bottom side of the shell, and a stirring assembly on the bottom side of the shell that can stir the inlet liquid inside the shell.

[0005] In this technical solution, the temperature sensor is in contact with the liquid inlet on the bottom side of the housing for constant temperature measurement. The stirring component can stir the drained liquid inside the housing, avoiding the temperature sensor's detection of the drained liquid temperature being too localized. When the heating layer is heated, the stirring component stirs the drained liquid, which can accelerate heat transfer. The outer side of the heating layer is fitted with an insulation layer, which can reduce heat loss to the outside and maintain the temperature stability inside the pump station, thereby improving energy efficiency and antifreeze effect. At the same time, the stirring component can also prevent sludge and other impurities from depositing on the bottom side of the housing.

[0006] In the above technical solution, the stirring assembly further includes a guide column that is perpendicularly connected to the bottom wall of the shell along the length of the shell, a fixed seat is slidably disposed on the guide column, and a stirring device is fixedly disposed on the fixed seat.

[0007] In this technical solution, the fixed seat and the guide column are connected by bolts or other fasteners. The fixed seat can be fixed on the guide column at the required height according to the actual situation to fix the height of the stirring device. The stirring device is existing technology and can be a submersible stirrer. It can effectively prevent impurities in the drain from depositing on the bottom wall of the shell, and at the same time can stir the drain in the shell, avoiding the temperature sensor from detecting the drain temperature too locally.

[0008] In the above technical solution, the heating layer is further defined as a graphite heating film.

[0009] In this technical solution, the graphite heating film can be directly heated by electricity; or it can be installed in a jacket, with a circulating heat medium (such as hot water or steam) inside the jacket to heat the fluid inside the pump station.

[0010] Furthermore, in the above technical solution, a vacuum insulation layer is provided inside the insulation layer.

[0011] In this technical solution, the insulation layer can be made of polyurethane foam, glass wool, rock wool, etc., while the vacuum insulation layer consists of two layers of metal film with a vacuum in between. Vacuum is the best insulation material because heat cannot travel in a vacuum. This design can greatly reduce the thermal bridging effect, that is, the phenomenon of heat being transferred to the outside through the pump station wall, thereby further improving the insulation effect.

[0012] In the above technical solution, the heating layer, temperature sensor and stirring assembly are all electrically connected to an external control cabinet.

[0013] In the above technical solution, the controller in the control cabinet is further equipped with a first rated temperature and a second rated temperature. When the drain temperature is lower than the first rated stable temperature, the heating layer heats the drain to transfer heat; when the drain temperature is higher than the second rated temperature, the heating layer stops heating.

[0014] In the above technical solution, the first rated temperature ranges from 0°C to 10°C.

[0015] In this technical solution, setting the first rated temperature above 0℃ effectively prevents the liquid inside the pump station from freezing. When the ambient temperature is below 0℃, the liquid inside the pump station is prone to freezing, leading to equipment damage or malfunction. Heating through a heating layer to maintain the internal temperature of the pump station above 0℃ effectively avoids this situation.

[0016] In the above technical solution, the second rated temperature range is further defined as 20°C to 40°C.

[0017] This technical solution ensures that the pump station operates under optimal conditions. Excessively high temperatures can cause overheating, while excessively low temperatures can affect normal operation. Therefore, when the temperature sensor detects that the discharge temperature exceeds 40°C, the heating layer will stop heating to maintain a stable internal temperature for the pump station.

[0018] In the above technical solution, the temperature sensor is further fixedly mounted on the support frame, the support frame is fixedly mounted on the bottom wall of the housing, and the shortest distance between the temperature sensor and the housing supported on the support frame is greater than 10cm.

[0019] In this technical solution, direct thermal interference from the heating layer to the temperature sensor is avoided. This ensures more accurate temperature data measured by the temperature sensor, improving the overall system's temperature control precision. The support frame provides stable support and ensures that the temperature sensor will not move due to vibration or other external factors during operation, which helps maintain the stability and measurement accuracy of the temperature sensor. Furthermore, the temperature sensor housing and support frame are connected by threaded fasteners for easy installation and disassembly.

[0020] In the above technical solution, the liquid inlet pipe is further provided with a crushing grid at the outlet inside the shell. The crushing grid is set on a fixed frame, and the fixed frame is set on a sliding guide rail.

[0021] In this technical solution, a gate is also installed at the outlet of the liquid inlet pipe. The gate is controlled by a screw hoist on the top of the shell. A ladder and a horizontal support platform are also installed inside the shell to facilitate regular maintenance and inspection by staff. The setting of the crushing grid is beneficial to crushing impurities in the discharged liquid, reducing the working pressure of the stirring components and facilitating the smooth discharge of the liquid by the sewage pump.

[0022] The beneficial effects of this utility model are:

[0023] 1. The temperature sensor contacts the liquid inlet on the bottom side of the housing to measure the temperature at all times. A first rated temperature and a second rated temperature are set. When the temperature displayed by the temperature sensor is lower than the first rated temperature, the heating layer heats up to generate heat. This heat is transferred through the contacting housing and the liquid inlet inside the housing, thus preventing the liquid inside the housing from freezing. When the temperature sensor detects that the drain temperature is higher than the second rated temperature, the heating layer stops heating. The stirring component agitates the drain inside the housing, preventing the temperature sensor from detecting the drain temperature too locally. Furthermore, the stirring component agitates the drain while the heating layer is heating, accelerating heat transfer. An insulation layer is fitted on the outside of the heating layer to reduce heat loss to the outside, maintaining a stable temperature inside the pump station, thereby improving energy efficiency and antifreeze performance. The stirring component also prevents sludge and other impurities from accumulating on the bottom side of the housing.

[0024] 2. A vacuum insulation layer is installed inside the insulation layer. The insulation layer can be made of polyurethane foam, glass wool, rock wool, etc. The vacuum insulation layer consists of two layers of metal film with a vacuum in between. Vacuum is the best insulation material because heat cannot be transmitted in a vacuum. This design can greatly reduce the thermal bridging effect, that is, the phenomenon of heat being transferred to the outside through the pump station wall, thereby further improving the insulation effect.

[0025] 3. The temperature sensor is fixedly mounted on a support frame, which is also fixed to the bottom wall of the housing, preventing direct thermal interference from the heating layer. This ensures more accurate temperature data measured by the sensor, improving the overall system's temperature control precision. The support frame provides stable support and prevents the temperature sensor from moving due to vibration or other external factors during operation, contributing to the sensor's stability and measurement accuracy. Furthermore, the temperature sensor housing and support frame are connected by threaded fasteners for easy installation and disassembly. Attached Figure Description

[0035] First embodiment:

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides an integrated pump station with antifreeze and heat preservation, including a shell 1, a mounting base 2 at the bottom of the shell 1, a cover plate 3 at the top, an inlet pipe 4 connected to the shell 1, a sewage pump 5 inside the shell 1, a sewage pipe assembly 6 connected to the sewage pipe assembly 6 connected to the outlet pipe 7, a heating layer 8 covering the outer wall of the shell 1, an insulation layer 9 abutting against the outer side of the heating layer 8, a temperature sensor 10 inside the shell 1, the temperature sensor 10 being able to contact the inlet liquid on the bottom side of the shell 1, and a stirring assembly 11 inside the bottom side of the shell 1, the stirring assembly 11 being able to stir the inlet liquid inside the shell 1.

[0037] The stirring assembly 11 includes a guide column 12 that is perpendicularly connected to the bottom wall of the shell 1 along the length of the shell 1. A fixed seat 13 is slidably disposed on the guide column 12, and a stirring device 14 is fixedly disposed on the fixed seat 13.

[0038] The fixed base 13 and the guide column 12 are connected by bolts or other fasteners. The fixed base 13 can be fixed on the guide column 12 at the required height according to the actual situation to fix the height of the stirring device 14. The stirring device 14 is a prior art and can be a submersible stirrer. It can effectively prevent impurities in the drain from depositing on the bottom wall of the shell 1. At the same time, it can stir the drain in the shell 1 and prevent the temperature sensor 10 from detecting the drain temperature too locally.

[0039] Heating layer 8 is a graphite heating film. The graphite heating film can be directly heated by electricity; or it can be installed in a jacket, with a circulating heat medium (such as hot water or steam) inside the jacket to heat the fluid inside the pump station.

[0040] The outer casing is made of metal materials such as stainless steel or carbon steel because these materials have high strength and good thermal conductivity, providing structural strength and ensuring that the pump station can withstand internal pressure and the influence of the external environment. At the same time, the good thermal conductivity helps with heat transfer in heating layer 8.

[0041] A vacuum insulation layer 15 is installed inside the insulation layer 9. The insulation layer 9 can be made of polyurethane foam, glass wool, rock wool, etc. The vacuum insulation layer 15 consists of two layers of metal film with a vacuum in between. Vacuum is the best insulation material because heat cannot travel in a vacuum. This design can greatly reduce the thermal bridging effect, that is, the phenomenon of heat being transferred to the outside through the pump station wall, thereby further improving the insulation effect.

[0042] The heating layer 8, temperature sensor 10, and stirring assembly 11 are all electrically connected to the external control cabinet 16.

[0043] The controller inside the control cabinet 16 is equipped with a first rated temperature and a second rated temperature. When the drain temperature is lower than the first rated temperature, the heating layer 8 heats the drain to transfer heat; when the drain temperature is higher than the second rated temperature, the heating layer 8 stops heating.

[0044] The first rated temperature range is 0℃ to 10℃. Setting the first rated temperature above 0℃ effectively prevents the liquid inside the pump station from freezing. When the ambient temperature is below 0℃, the liquid inside the pump station is prone to freezing, leading to equipment damage or malfunction. Heating through heating layer 8 maintains the internal temperature of the pump station above 0℃, effectively preventing this from happening.

[0045] The second rated temperature range is 20°C to 40°C. This ensures the pump station operates under optimal conditions. Excessive temperature can cause overheating, while excessively low temperature will affect normal operation. Therefore, when temperature sensor 10 detects a discharge temperature above 40°C, heating layer 8 will stop heating to maintain a stable internal temperature for the pump station.

[0046] Temperature sensor 10 contacts the liquid inlet on the bottom side of housing 1 to measure the temperature at all times. A first rated temperature and a second rated temperature are set. When the temperature displayed by temperature sensor 10 is lower than the first rated temperature, heating layer 8 heats up to generate heat. This heat is transferred through the contacting housing 1 and the liquid inlet inside the housing 1, thus preventing the liquid inside the housing 1 from freezing. When temperature sensor 10 detects that the drain temperature is higher than the second rated temperature, heating layer 8 stops heating. The stirring assembly 11 stirs the drain inlet inside housing 1, preventing the temperature sensor 10 from detecting the drain temperature too locally. Furthermore, the stirring assembly 11 accelerates heat transfer during heating layer 8 heating. An insulation layer 9 is fitted onto the outside of heating layer 8 to reduce heat loss to the outside, maintaining a stable temperature inside the pump station, thereby improving energy efficiency and antifreeze effect. The stirring assembly 11 also prevents sludge and other impurities from depositing on the bottom side of housing 1.

[0047] Temperature sensor 10 is fixedly mounted on support frame 17, which is fixedly mounted on the bottom wall of housing 1. The shortest distance between temperature sensor 10 and housing 1 on support frame 17 is greater than 10cm. This prevents direct thermal interference from heating layer 8 to temperature sensor 10. This ensures more accurate temperature data measured by temperature sensor 10, improving the overall temperature control accuracy of the system. Support frame 17 provides stable support and ensures that temperature sensor 10 will not move due to vibration or other external factors during operation, which helps maintain the stability and measurement accuracy of temperature sensor 10. At the same time, housing 1 and support frame 17 are connected by fasteners via threads, facilitating installation and disassembly.

[0048] A pulverizing grid 18 is installed at the outlet of the liquid inlet pipe 4 inside the housing 1. The pulverizing grid 18 is mounted on a fixed frame 19, which is mounted on a sliding guide rail 20. A gate 21 is also installed at the outlet of the liquid inlet pipe 4. The gate 21 is controlled by a screw-operated hoist 22 at the top of the housing 1. A ladder 23 and a horizontal support platform 24 are also installed inside the housing 1 to facilitate regular maintenance and inspection by personnel. The pulverizing grid 18 helps to pulverize impurities in the discharged liquid, reduces the working pressure of the stirring assembly 11, and facilitates the smooth discharge of the liquid by the sewage pump 5.

[0049] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
