Description

Technical Field

[0001] This utility model relates to the field of side-filtration system technology, and in particular to an emergency water replenishment device for side-filtration systems. Background Technology

[0002] Side-channel filtration systems are core auxiliary purification equipment in the treatment of industrial circulating water, chemical fluids, and other media. They divert a portion of the media through a bypass filtration branch in the main circulation pipeline. The filter media layer traps suspended solids, colloids, biological slime, and other impurities in the water, reducing turbidity. Simultaneously, a high-temperature treatment stage is often included to kill bacteria, algae, and other microorganisms in the water. Combined with chemical treatment, this further prevents system corrosion and scaling, providing dual protection for water cleanliness. This system effectively protects the internal piping of main equipment such as heat exchangers and pumps, reducing the risk of wear and blockage from impurities, extending equipment lifespan, and improving operational economy. It is widely used in industrial water, power, pharmaceutical, and food processing industries, where high water quality is required.

[0003] In the existing technology, the typical operating process is as follows: after the medium enters the side filter branch, it is first treated with high temperature to complete the sterilization, and then impurities are removed by filtration through the filter media. After purification, it is returned to the main circulation system. When the filter media traps more impurities, causing the pressure difference to reach the set value, the system starts backwashing to discharge pollutants and restore filtration efficiency.

[0004] However, during the long-term operation of the bypass filtration system, the medium in the system is prone to shortage due to factors such as medium evaporation, leakage, and backwash drainage. If it is not replenished in time, the system liquid level will be lower than the safe operating threshold, which will not only reduce the filtration and high-temperature treatment efficiency, but may also cause failures such as dry friction and overheating damage to the main equipment due to insufficient medium.

[0005] Accordingly, this application proposes an emergency water replenishment device for a side-filtration system. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an emergency water replenishment device for a side-filtration system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The emergency water replenishment device for the side-filter system includes a water inlet system, four water replenishment components and four alarm components. A mounting bracket is fixedly installed below the water inlet system, and a heating pipe is fixedly installed at one end of the water inlet system. Four water storage tanks are connected to the heating pipe.

[0009] The water replenishment component includes: an upper drain plate and a lower drain plate;

[0010] The upper drain plate is rotatably connected inside the water storage tank, and the lower drain plate is fixedly connected inside the water storage tank.

[0011] The alarm component includes: a whistle plug and a linkage;

[0012] The whistle plug is slidably connected to the water storage tank, and the connecting rod is fixedly connected to the bottom of the whistle plug.

[0013] Preferably, the water replenishment component further includes: a servo motor, several troughs, a bracket, and a water level sensor;

[0014] The servo motor is fixedly installed on the water storage tank, and several of the leakage channels are staggered on the upper and lower leakage plates. The bracket is fixedly connected to the inner wall of the heating tube, and the water level sensor is fixedly installed on the bracket.

[0015] Preferably, the alarm assembly further includes: a sleeve, a lead screw, a partition, and a slider;

[0016] The sleeve is fixedly connected to the upper leak plate, the lead screw is slidably connected inside the sleeve, the partition is fixedly connected inside the water storage tank, and the slider is slidably connected to the partition.

[0017] Preferably, a second bevel gear is rotatably connected below the lower drain plate, and a first bevel gear is fixedly connected to the servo motor drive shaft. The first bevel gear meshes with the second bevel gear, and the second bevel gear is fixedly connected to the upper drain plate.

[0018] Preferably, one end of the slider is fixedly connected to the lead screw, and the other end is fixedly connected to the connecting rod. The slider is slidably connected to the partition plate. The whistle plug has an opening. A water outlet pipe group is connected to the outside of the heating tube. Compressed gas is stored in the enclosed space above the partition plate.

[0019] Preferably, a tubular heater is fixedly installed inside the heating tube, and several filter plates are fixedly connected inside the heating tube. The tubular heater tubes are fixedly installed on the filter plates. The connection between the slider and the partition plate is sealed, and the connection between the upper and lower filter plates is sealed.

[0020] This utility model has the following beneficial effects:

[0021] 1. Through the water replenishment component, when the water level sensor detects that the water level in the heating tube is low, it sends a signal to the control system, causing the servo motor to drive the first bevel gear to rotate, which in turn causes the second bevel gear to drive the upper leak plate to rotate, thereby connecting the leak groove on the upper leak plate with the leak groove on the lower leak plate. The water pre-stored in the water tank flows continuously into the heating tube through this connecting channel, preventing the tubular heater in the heating tube from dry burning due to lack of medium cooling and damaging the bypass filtration system.

[0022] Second, through the alarm component, when the second bevel gear rotates, the upper leak plate can drive the sleeve to rotate, thereby causing the lead screw to drive the slider and connecting rod to slide upward, so that the opening on the whistle plug slides out of the water storage tank. At this time, the air pressure in the closed space above the partition plate quickly leaks out through the opening. The airflow forms airflow vibration at the opening, which in turn emits a sound that can be clearly perceived by the operator, so that the operator can quickly know that the emergency water replenishment device is in working condition, which is convenient for subsequent monitoring and handling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1:

[0031] Reference Figures 1 to 3The side-filtration system emergency water replenishment device includes a water inlet system 1, four water replenishment components, and four alarm components. A mounting bracket 2 is fixedly installed below the water inlet system 1 to support and fix the water inlet system 1. A heating pipe 3 is fixedly installed at one end of the water inlet system 1. The heating pipe 3 is used to transport water replenishment and provide a mounting carrier for the tubular heater 31 and the filter plate 32. Its heating function, together with the filter plate 32, realizes the disinfection and filtration of the water replenishment. Four water storage tanks 5 are connected to the heating pipe 3. The water storage tanks 5 are used to pre-store the emergency water replenishment medium and provide a mounting base for the water replenishment components and alarm components.

[0032] The heating tube 3 is fixedly installed on the mounting bracket 2. The mounting bracket 2 also provides fixed support for the heating tube 3 to ensure the overall structural stability. The outside of the heating tube 3 is connected to the water outlet pipe group 4. The water outlet pipe group 4 is used to transport the disinfected and filtered water in the heating tube 3 to the side filtration system. The side filtration system is the main filtration equipment. The disinfection and filtration function of the emergency water replenishment device is the pre-treatment of the side filtration system. A tubular heater 31 is fixedly installed inside the heating tube 3. The tubular heater 31 is used to heat the water in the heating tube 3. The water is disinfected by raising the temperature. At the same time, the filtration conditions are optimized to improve the filtration effect of the filter plate 32. Several filter plates 32 are fixedly connected inside the heating tube 3. The filter plates 32 are used to filter impurities in the water. They work with the disinfection function of the tubular heater 31 to complete the pretreatment of the water and provide installation and fixing points for the tubular heater 31. The tubular heater 31 is fixedly installed on the filter plate 32. The filter plate 32 is used to achieve a stable assembly of the tubular heater 31 inside the heating tube 3.

[0033] In this embodiment, the water inlet system 1 delivers the water to be filtered to the heating pipe 3. The mounting bracket 2 provides fixed support for the water inlet system 1 and the heating pipe 3. The tubular heater 31 inside the heating pipe 3 is fixedly installed through the filter plate 32. The tubular heater 31 heats the water to be filtered delivered by the water inlet system 1 to achieve sterilization treatment. At the same time, heating optimizes the filtration conditions. The filter plate 32 inside the heating pipe 3 filters impurities in the water to be filtered. It works with the tubular heater 31 to complete the pretreatment of the water to be filtered. The water to be filtered after sterilization and filtration is delivered to the filtration system through the water outlet pipe group 4.

[0034] Example 2:

[0035] Unlike Example 1, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment also has the following further features:

[0036] The water replenishment assembly includes: an upper drain plate 61, a lower drain plate 62, a servo motor 6, several drain channels 65, a bracket 64, and a water level sensor 63;

[0037] The upper leak plate 61 is rotatably connected to the water storage tank 5 and is used to control the water supply flow by adjusting the overlap of the leak grooves 65 by rotation. The lower leak plate 62 is fixedly connected to the water storage tank 5 and is used to cooperate with the upper leak plate 61 to form a water supply channel and provide an installation reference. The servo motor 6 is fixedly installed on the water storage tank 5. Several leak grooves 65 are staggered on the upper leak plate 61 and the lower leak plate 62 to form a water supply flow channel. The bracket 64 is fixedly connected to the inner wall of the heating tube 3 and is used to fix the water level sensor 63. The water level sensor 63 is fixedly installed on the bracket 64 and is used to detect the water level in the heating tube 3 and provide a feedback signal.

[0038] A second bevel gear 9 is rotatably connected below the lower leak plate 62 to transmit power and drive the upper leak plate 61 to rotate. A first bevel gear 8 is fixedly connected to the transmission shaft of the servo motor 6. The first bevel gear 8 can rotate on the water storage tank 5. The first bevel gear 8 and the second bevel gear 9 are meshed and connected. Power transmission and steering conversion are realized through gear meshing. The second bevel gear 9 is fixedly connected to the upper leak plate 61 to drive the upper leak plate 61 to rotate synchronously. The connection between the upper leak plate 61 and the lower leak plate 62 is sealed to prevent medium leakage during water replenishment.

[0039] In this embodiment, when the water level sensor 63 detects that the water level in the heating tube 3 is lower than the safe operating threshold, it immediately sends a low water level signal to the control system. After receiving the signal, the control system triggers the servo motor 6 to start, driving the first bevel gear 8. The first bevel gear 8 drives the upper leak plate 61 to rotate along its own axis in the water storage tank 5 through the second bevel gear 9. As the upper leak plate 61 rotates, the groove 65 on its surface gradually forms a through channel with the groove 65 of the lower leak plate 62. The water pre-stored in the water storage tank 5 flows continuously into the heating tube 3 through this through channel, preventing the tubular heater 31 in the heating tube 3 from dry burning due to lack of medium cooling and damaging the side filter system.

[0040] Example 3:

[0041] Reference Figures 3 to 5 Compared to Embodiment 1 and Embodiment 2, in this embodiment:

[0042] The alarm assembly includes: a whistle plug 75, a connecting rod 74, a sleeve 7, a lead screw 71, a partition 72, and a slider 73;

[0043] The whistle plug 75 is slidably connected to the water tank 5 and is used to expand and contract the opening by sliding, thereby controlling air pressure leakage and alarm sounding. The connecting rod 74 is fixedly connected below the whistle plug 75 and is used to transmit the driving force of the slider 73 and drive the whistle plug 75 to slide. The sleeve 7 is fixedly connected to the upper leak plate 61 and is used to rotate synchronously with the upper leak plate 61 and provide sliding guidance for the lead screw 71. The lead screw 71 is slidably connected inside the sleeve 7 and is used to convert the rotational motion of the sleeve 7 into axial displacement and drive the slider 73 to move. The partition plate 72 is fixedly connected inside the water tank 5 and is used to divide the space to form a closed air pressure environment and provide sliding support for the slider 73. The slider 73 is slidably connected to the partition plate 72 and is used to transmit the power of the lead screw 71 and drive the connecting rod 74 to move.

[0044] One end of the slider 73 is fixedly connected to the lead screw 71 to receive the axial driving force of the lead screw 71, and the other end is fixedly connected to the connecting rod 74 to transmit the driving force to the connecting rod 74. The slider 73 is slidably connected to the partition 72 to achieve stable sliding along the partition 72. The whistle plug 75 has an opening to generate airflow vibration and emit an alarm sound when air pressure leaks. Compressed gas is stored in the closed space above the partition 72 to provide an air pressure source for the alarm sound. The connection between the slider 73 and the partition 72 is sealed to ensure the airtightness of the closed space above the partition 72 and prevent air pressure leakage from affecting the alarm effect.

[0045] In this embodiment, when the water replenishment component is activated, the second bevel gear 9 is fixedly connected to the upper leak plate 61, and the sleeve 7 rotates together with the upper leak plate 61. Under the rotational force and guiding action, the lead screw 71 generates axial displacement, driving the slider 73, which is fixedly connected to one end of the lead screw 71, to slide upward along the partition 72 inside the water storage tank 5. Then, through the connecting rod 74, it pushes the whistle plug 75 to move upward synchronously, so that the preset opening on the whistle plug 75 gradually slides out of the water storage tank 5. Before this, the space above the partition 72 forms a closed air pressure environment due to the storage of the medium and the water replenishment process in the water storage tank 5. When the opening of the whistle plug 75 is exposed to the outside of the water storage tank 5, the air pressure in the closed space quickly leaks out through the opening. The airflow forms airflow vibration at the opening, thereby emitting a sound that can be clearly perceived by the operator, so that the operator can quickly know that the emergency water replenishment device is in working condition, which is convenient for subsequent monitoring and handling.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
