Description

Technical Field

[0001] This utility model relates to the technical field of automatic exhaust equipment for heating units, specifically to an automatic exhaust device for supplementing the secondary network of a heating unit's primary network. Background Technology

[0002] In heating systems, the water replenishment system is a critical piece of equipment. In well-managed enterprises, water is replenished from the primary network to the secondary network. However, impurities are usually present in the water source during the replenishment process. The common practice is to use a post-filter to remove these impurities. However, these filters are prone to clogging, which can cause water replenishment to stop or even burn out the water replenishment pump. Therefore, we propose an automatic air venting device for primary network replenishment to secondary network in heating units. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an automatic exhaust device for primary network to secondary network of heating unit.

[0004] The technical solution adopted by this utility model to solve its technical problem is an automatic exhaust device for primary network to secondary network of heating unit, including a tank body. The outer periphery of the tank body is provided with an inlet pipe and an outlet pipe for water replenishment, and the inner side of the tank body is equipped with a shaped plate corresponding to the inlet pipe. The outer periphery surface of the shaped plate is provided with vertical holes for exhaust, and there are multiple sets of vertical holes.

[0005] The inner side of the tank is fitted with a conical tube for dividing the space, and the inner circumference of the conical tube is provided with a spiral groove for guiding the flow. The bottom end surface of the conical tube is screwed with a ring seat for support, and the inner circumference of the ring seat is integrally constructed with a support rod for auxiliary support. There are multiple sets of support rods, and the multiple sets of support rods are integrally constructed with a vertical tube that is inserted into the conical tube.

[0006] By adopting the above technical solution, in the process of using the automatic secondary exhaust equipment for the primary network of the heating unit, the water inlet pipe is connected to the primary network water supply pipe, while the water outlet pipe is conveniently connected to the secondary network water inlet. When the supplemented water source enters the tank, the water source can be bypassed and guided by the shaped plate. At the same time, the air in the water source can be directly discharged to the top of the tank from the multiple sets of vertical holes on the top side of the shaped plate, which facilitates subsequent discharge and reduces the impact of gas in the subsequent water supply process.

[0007] After being turbulent by the conical plate, the water enters the conical tube. The spiral grooves on the inner circumference of the conical tube facilitate the flow of the water, causing it to spiral through the tube and into the bottom of the tank. Simultaneously, small solid particles and floating debris carried in the water are thrown against the inner wall of the tank bottom by the centrifugal force generated by the spiral conveyor, facilitating their settling at the bottom. The conical tube's conical structure also effectively intercepts these particles. Furthermore, the vertical pipe on the inner circumference of the ring seat at the bottom of the conical tube facilitates the diversion of the returning and spiral-conveyed water, further reducing the movement of small solid particles and floating debris due to the direction of the water flow. This results in a more stable and smooth water replenishment process.

[0008] Specifically, the bottom surface of the vertical pipe is integrally constructed with an inclined ring for guiding flow, and an adhesive ring that abuts against the tapered pipe is bonded to the inner side of the ring seat. The outer circumferential surface of the ring seat is equipped with a crossbar for rotation, and there are multiple sets of crossbars.

[0009] By adopting the above technical solution, the high-temperature resistant rubber ring on the ring seat can reduce the damage caused by the friction between the ring seat and the conical tube. The crossbar on the outer periphery of the ring seat makes it easier to disassemble and assemble. The inclined ring on the bottom side of the vertical tube can provide a certain flow guiding performance, so that small solid particles and floating objects sliding along the spiral groove on the inner periphery of the conical tube can be more smoothly thrown to the inner wall of the tank.

[0010] Specifically, the inner side of the tank is equipped with an arc-shaped column corresponding to the conical tube, and a drain valve is installed on the inner side of the bottom opening of the tank.

[0011] By adopting the above technical solution, the arc-shaped column on the inner side of the tank can help guide the sludge that settles at the bottom of the tank, so that the sludge can accumulate around the bottom of the tank. This reduces the situation where the water flowing back from the vertical pipe carries sludge. The drain valve is easy to operate and facilitates the discharge of sludge that settles inside the tank.

[0012] Specifically, the top surface of the tank is fitted with a three-way pipe for guiding flow, and the two ends of the three-way pipe away from the tank are respectively fitted with a ball valve body and an automatic exhaust valve.

[0013] By adopting the above technical solutions, the three-way pipe at the top of the tank facilitates venting, the ball valve body facilitates manual operation and manual control of venting, and the automatic venting valve facilitates automatic operation and automatic venting when the air pressure is high.

[0014] Specifically, the outer peripheral surface of the tank is equipped with observation windows, and there are multiple sets of observation windows.

[0015] By adopting the above technical solution, multiple sets of observation windows on the outer periphery of the tank facilitate personnel to observe the internal structure of the tank and understand the operation of the internal structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of inlet pipe, outlet pipe, shaped plate and vertical holes, allows for the use of the automatic secondary exhaust equipment for the primary network of the heating unit. The inlet pipe is connected to the primary network water supply pipe, while the outlet pipe is conveniently connected to the secondary network water inlet. When the supplemented water source enters the tank, the shaped plate can be used to bypass and guide the water source. At the same time, the air in the water source can be directly discharged to the top of the tank from the multiple sets of vertical holes on the top side of the shaped plate, which facilitates subsequent discharge and reduces the impact of gas during subsequent water replenishment.

[0018] 2. The technical solution of this application, through the design of a conical tube, spiral groove, ring seat, support rod and vertical pipe, allows water to enter the conical tube after being turbulent by the conical plate. The spiral groove on the inner circumference of the conical tube facilitates the guidance of the water and allows the water to form a spiral force to pass through the conical tube and enter the bottom side of the tank. At the same time, small solid particles and floating objects carried in the water can be thrown to the inner wall of the bottom side of the tank by the centrifugal force generated by the spiral conveying, and can easily settle at the bottom of the tank. The conical tube with a conical structure can easily intercept small solid particles and floating objects, and the vertical pipe on the inner circumference of the ring seat at the bottom of the conical tube can easily divert the water source of the return flow and the spiral conveying, thereby further reducing the situation where small solid particles and floating objects are moved by the direction of the water source, thus enabling more stable and smooth water replenishment.

[0019] 3. The technical solution of this application has very low water resistance, which can be ignored, and eliminates the problem of cavitation damage to the water supply pump; it can remove dirt and clean small solid particles and floating objects; it is easy to clean, without the need to stop operation, and can discharge sewage online; it is easy to install, with a low height, and the inlet and outlet are horizontally installed, making the pipeline installation simple and not affecting the space; it can thoroughly vent air, and the equipment has a large air storage and dirt removal capacity, allowing operators to perform venting and sewage discharge operations for a longer period of time.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3 This utility model provides a technical solution: an automatic exhaust device for primary network replenishment and secondary network exhaust of a heating unit, comprising a tank 1, an inlet pipe 2 and an outlet pipe 3 for water replenishment on the outer periphery of the tank 1, and a scalloped plate 4 corresponding to the inlet pipe 2 mounted on the inner side of the tank 1. The outer periphery of the scalloped plate 4 is provided with vertical holes 5 for exhaust, and there are multiple sets of vertical holes 5. A conical tube 6 for space division is mounted on the inner side of the tank 1, and a spiral groove 7 for flow guidance is provided on the inner periphery of the conical tube 6. A ring seat 8 for support is screwed onto the bottom end surface of the conical tube 6, and a support rod 9 for auxiliary support is integrally constructed on the inner periphery of the ring seat 8, and there are multiple sets of support rods 9. A vertical pipe 10 that is inserted into the conical tube 6 is integrally constructed between the multiple sets of support rods 9.

[0027] In use, during the operation of the automatic secondary exhaust equipment for the primary network of the heating unit, the inlet pipe 2 is connected to the primary network water supply pipe, while the outlet pipe 3 is conveniently connected to the secondary network water inlet. When the supplemented water enters the tank 1, the water source can be bypassed and guided by the shaped plate 4. At the same time, the air in the water source can be directly discharged from the multiple sets of vertical holes 5 on the top side of the shaped plate 4 to the top of the tank 1, which facilitates subsequent discharge and reduces the impact of gas during subsequent water replenishment.

[0028] After being turbulent by the conical plate 4, the water source enters the conical tube 6. The spiral groove 7 on the inner circumference of the conical tube 6 facilitates the guidance of the water source, allowing it to form a spiral force as it passes through the conical tube 6 and enters the bottom side of the tank 1. At the same time, small solid particles and floating objects carried in the water source can be thrown onto the inner wall of the bottom side of the tank 1 by the centrifugal force generated by the spiral conveying, and can easily settle at the bottom of the tank 1. The conical tube 6 with its conical structure can easily intercept small solid particles and floating objects. The vertical pipe 10 on the inner circumference of the ring seat 8 at the bottom of the conical tube 6 can easily divert the water source from the return flow and the spiral conveying, thereby further reducing the movement of small solid particles and floating objects due to the direction of the water source, thus enabling a more stable and smooth water replenishment operation.

[0029] like Figure 2 and Figure 3 As shown, the bottom surface of the vertical pipe 10 is integrally constructed with an inclined ring 11 for guiding the flow, and the inner side of the ring seat 8 is bonded with a rubber ring 14 that abuts against the tapered pipe 6. The outer circumferential surface of the ring seat 8 is equipped with a horizontal bar 15 for rotation, and there are multiple sets of horizontal bars 15.

[0030] During use, the high-temperature resistant rubber ring 14 on the ring seat 8 helps to reduce the damage caused by the friction between the ring seat 8 and the conical tube 6. The horizontal bar 15 on the outer periphery of the ring seat 8 makes it easier to disassemble and assemble the ring seat 8. The inclined ring 11 on the bottom side of the vertical tube 10 provides a certain flow guiding performance, so that small solid particles and floating objects sliding along the spiral groove 7 on the inner periphery of the conical tube 6 can be more smoothly thrown to the inner wall of the tank 1.

[0031] like Figure 2 As shown, the inner side of the tank body 1 is equipped with an arc-shaped column 12 corresponding to the conical tube 6, and the inner side of the bottom opening end of the tank body 1 is equipped with a drain valve 13.

[0032] During use, the arc-shaped column 12 on the inner side of the tank 1 helps to guide the dirt that settles at the bottom of the tank 1, so that the dirt can accumulate around the bottom of the tank 1, which helps to reduce the situation where the water flowing back from the vertical pipe 10 carries dirt and flows. The drain valve 13 is easy to operate and facilitates the discharge of dirt that settles inside the tank 1.

[0033] like Figure 1 and Figure 2 As shown, a three-way pipe 17 for guiding flow is installed on the top surface of the tank body 1, and a ball valve body 18 and an automatic exhaust valve 19 are respectively installed at the two ends of the three-way pipe 17 away from the tank body 1.

[0034] When in use, the three-way pipe 17 on the top of the tank 1 facilitates venting, while the ball valve body 18 facilitates manual operation and manual control of venting, and the automatic venting valve 19 facilitates automatic operation and automatic venting when the air pressure is high.

[0035] like Figure 1 As shown, the outer circumferential surface of the tank 1 is equipped with observation windows 16, and there are multiple sets of observation windows 16.

[0036] During use, the multiple sets of observation windows 16 on the outer periphery of the tank 1 facilitate personnel to observe the internal structure of the tank 1 and understand the operation of the internal structure of the tank 1.

[0037] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the automatic secondary air venting equipment for the primary network of the heating unit, the inlet pipe 2 is connected to the primary network water supply pipe, while the outlet pipe 3 is conveniently connected to the secondary network inlet. When the replenished water enters the tank 1, the conical plate 4 can be used to circulate and guide the water source. Simultaneously, air in the water source can be directly discharged from the multiple sets of vertical holes 5 on the top side of the conical plate 4 to the top of the tank 1, facilitating subsequent discharge. The three-way pipe 17 at the top of the tank 1 facilitates air venting, while the ball valve 18 allows for manual operation and control of air venting. The automatic air venting valve 19 allows for automatic operation and automatic air venting when the air pressure is high, thereby reducing the impact of gas during subsequent water replenishment. Simultaneously, after being turbulent by the conical plate 4, the water source enters the conical pipe 6. The spiral groove 7 on the inner circumference of the conical pipe 6 facilitates the guidance of the water source and allows the water source to form a spiral force as it passes through the conical pipe. The water enters the bottom of the tank 1, and small solid particles and floating objects carried in the water source are thrown onto the inner wall of the bottom of the tank 1 by the centrifugal force generated by the spiral conveyor, which facilitates their settling at the bottom of the tank 1. The conical tube 6 with its conical structure facilitates the interception of small solid particles and floating objects, and the vertical pipe 10 on the inner circumference of the ring seat 8 at the bottom of the conical tube 6 can facilitate the diversion of the water source from the return flow and the spiral conveyor, thereby further reducing the movement of small solid particles and floating objects by the direction of the water source, thus enabling more stable and smooth water replenishment. The arc-shaped column 12 on the inner side of the tank 1 facilitates the auxiliary guidance of the dirt settled at the bottom of the tank 1, so that the dirt can accumulate around the bottom of the tank 1, which helps to reduce the flow of dirt carried by the water source returning from the vertical pipe 10. The drain valve 13 is easy to operate and facilitates the discharge of dirt settled inside the tank 1, thus enabling the automatic exhaust equipment to be used more stably when replenishing the secondary network of the heating unit's primary network.
