Description

Technical Field

[0001] The present application relates to the field of circulating pump water tanks, and more specifically, to a boiler circulating pump water tank. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The boiler water tank is used in a closed water circulation system to balance the water volume and pressure, avoiding frequent opening of the safety valve and frequent replenishment of water by the automatic water replenishment valve. In addition to accommodating expansion water, the boiler water tank can also serve as a water replenishment tank. The boiler water tank is filled with nitrogen to obtain a larger volume to accommodate the expansion water. The high and low pressure boiler water tanks can use their own pressure to replenish water to the pressure stabilization system in parallel. After the water tank is used for a long time, scale may form inside, so it is required for subsequent cleaning by staff.

[0003] The existing boiler water tank cleaning method is manual cleaning, but some boiler water tanks are large in size. When the scale needs to be cleaned, it may take a long time, which reduces the efficiency of descaling and affects the subsequent use of the boiler. Therefore, we propose a boiler circulating pump water tank. Utility Model Content

[0004] In order to solve the above problems, the present application provides a boiler circulating pump water tank, which adopts the following technical solution:

[0005] A boiler circulating pump water tank comprises a box body, a water inlet pipe is provided at the top of the box body, two symmetrically distributed sewage frames are fixedly installed at the bottom of the box body, and the top ends of the two sewage frames pass through the box body, an installation box is provided between the two sewage frames, a protective box is fixedly installed on one side of the box body, and a reduction motor is fixedly installed in the protective box, a reciprocating screw is rotatably installed in the box body, and one end of the reciprocating screw passes through the protective box and is fixedly connected to the output shaft of the reduction motor, a descaling assembly is provided on the side wall of the reciprocating screw, a sealing assembly is provided in each of the two sewage frames, sewage pipes are provided on opposite sides of the two sewage frames, and conveying assemblies are provided in the two sewage pipes.

[0006] By adopting the above technical scheme, when the equipment is used, when it is necessary to descale the inside of the box, the reciprocating screw is driven to rotate by the reduction motor, and the side wall of the reciprocating screw is provided with a descaling component. When the reciprocating screw rotates, the descaling component is located in the box and performs reciprocating motion, which can play a role in removing scale from the inside of the box. When the scale is removed, the sealing component is operated to open the upper port of the sewage discharge frame. After the dirt enters the sewage discharge frame, the dirt is discharged through the sewage discharge pipe by the conveying component, and clean water can be injected into the box through the water inlet pipe, which plays a role in further cleaning the inside of the box. There is no need for staff to enter the box to descale, which reduces the workload of staff and improves the descaling efficiency of the box.

[0007] Furthermore, the descaling assembly includes two rings sleeved on the side walls of the reciprocating screw, the two rings are symmetrically distributed on the side walls of the reciprocating screw, cleaning plates are fixedly installed on the side walls at both ends of the reciprocating screw, a movable plate is sleeved on the side walls of the reciprocating screw, and a first scraper is fixedly installed on both ends of the two movable plates, support plates are fixedly installed on the bottom and top ends of the movable plates, and a second scraper is fixedly installed on the opposite ends of the two support plates.

[0008] By adopting the above technical scheme, the reciprocating screw is driven to rotate by the reduction motor. When the reciprocating screw rotates, the moving plate moves synchronously with the first scraper, the support plate and the second scraper, and the first scraper and the second scraper are in contact with the inside of the opposite side of the box. When the first scraper and the second scraper move, they can play a role in removing scale on the inner wall of the box, and the reciprocating screw synchronously drives the cleaning plate to rotate. Through the rotation of the cleaning plate, it plays a role in cleaning the inner wall of the box synchronously. The cooperation of the first scraper, the second scraper and the cleaning plate is beneficial to improve the efficiency of removing scale from the box.

[0009] Furthermore, two symmetrically distributed stabilizing rods are fixedly installed between the movable plate and the first scraper, and between the support plate and the second scraper.

[0010] By adopting the above technical solution, stabilizing rods are provided between the movable plate and the first scraper, and between the support plate and the second scraper, so as to support and stabilize the first scraper and the second scraper.

[0011] Furthermore, two symmetrically distributed mounting plates are fixedly installed on one side of the movable plate away from the protective box, and a push plate is provided under the two mounting plates. Telescopic rods are fixedly installed on the bottom ends of the two mounting plates, and the ends of the two telescopic rods are fixedly connected to the top of the push plate.

[0012] By adopting the above technical solution, when the scale is removed, the push plate is driven downward by the telescopic rod and contacts the inner wall of the bottom end of the box. The push plate is driven to move by the reciprocating screw. The push plate can push the scale at the bottom of the box to the sewage discharge frame, which is convenient for subsequent discharge of the equipment.

[0013] Furthermore, the sealing assembly includes a baffle plate slidably installed in the two sewage discharge frames, a cylinder is fixedly installed on one side of the two sewage discharge frames, and the two baffle plates slide through the sewage discharge frames in the same group near one end of the cylinder in the same group, and an inverted "L"-shaped connecting plate is fixedly installed on one end of the baffle plate passing through the sewage discharge frame, and the cylinder is fixedly connected to the side opposite to the vertical section of the connecting plate in the same group.

[0014] By adopting the above technical solution, the cylinder drives the same group of connecting plates to move with the baffle in the sewage frame, which plays the role of opening and blocking the port of the sewage frame. When scale needs to be discharged, the cylinder drives the baffle to move to the outside of the sewage frame. When the scale is discharged, the cylinder drives the baffle to return to its original position, which plays the role of blocking the sewage frame, making it convenient for the equipment to store water later.

[0015] Furthermore, sliding blocks are fixedly installed on both sides of the two baffles, and the inner walls of the two sewage discharge frames are provided with sliding grooves matching the sliding blocks on the same side.

[0016] By adopting the above technical solution, when the baffle slides in the sewage discharge frame, the baffle moves with the slider in the slide groove on the same side. The cooperation between the slider and the slide groove is conducive to maintaining the stability of the movement of the baffle.

[0017] Furthermore, the conveying assembly includes a double-axis motor fixedly installed in the installation box, and the inner walls of the two sewage discharge frames close to the installation box are both rotatably installed with rotating rods, and the two rotating rods extend into the sewage pipes of the same group away from one end of the installation box, and the side walls of the two rotating rods are fixedly sleeved with spiral conveying blades, and the two rotating rods extend into the installation box at one end away from the sewage pipes of the same group, and the two rotating rods pass through one end of the installation box and are fixedly connected to the end of the conveying shaft on the same side of the double-axis motor, and two symmetrically distributed inclined blocks are fixedly installed in the two sewage discharge frames.

[0018] By adopting the above technical scheme, when scale enters the sewage discharge frame, the dual-axis motor drives the connected rotating rods to rotate synchronously, and the two rotating rods drive the same group of spiral conveying blades to rotate. The spiral conveying blades rotate to discharge the scale in the sewage discharge frame through the sewage discharge pipe. In addition, two symmetrically distributed inclined blocks are provided in the two sewage discharge frames to facilitate the accumulation of scale entering the sewage discharge frame in the middle position of the sewage discharge frame, so that the spiral conveying blades can discharge the scale, which is beneficial to improve the discharge efficiency of the equipment.

[0019] Furthermore, the side wall of the box body is sleeved with reinforcement rods distributed in a straight line, support rods are provided between the reinforcement rods, and rubber blocks distributed in a rectangular array are provided between the reinforcement rods and the box body.

[0020] By adopting the above technical solution, the outer side of the box body plays a role in protecting the box body through the arrangement of reinforcement rods, support rods and rubber blocks, which is beneficial to reducing the degree of damage to the box body caused by impact of foreign objects.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] (1) In the present application, by setting up a descaling component, a reduction motor drives the reciprocating screw to rotate, thereby causing the movable plate to move with the first scraper and the second scraper, thereby cleaning the dirt inside the box body. The reciprocating screw drives the cleaning plate to rotate, thereby cleaning the inner walls of both ends of the box body, which is beneficial to improving the descaling efficiency of the equipment without the need for manual cleaning.
