Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of the power industry, specifically to a regulating installation structure for a circulating water pump. Background Technology
[0002] The coal-fired power industry is facing new opportunities and challenges, making cold-section optimization imperative. Currently, the conventional method is to optimize back pressure by switching between dual-speed circulating pumps. The proposed solution uses a fixed-frequency pump, increasing the number of pumps to connect the circulating water systems of two units. By optimizing back pressure through pump start-stop, energy-saving effects are achieved.
[0003] Traditional circulating pump mounting brackets simply involve screwing a few steel pipes onto the outside of the circulating pump to support it. When the inlet and outlet are located at higher positions, the traditional mounting brackets lack adjustment devices, necessitating the separation of the circulating pump from the return tank or disassembly and maintenance of the circulating pump. The pump's weight also increases the operator's workload. Summary of the Invention
[0004] The purpose of this utility model is to provide an adjustable installation structure for a circulating water pump to solve the above-mentioned defects caused by the prior art.
[0005] An adjustable installation structure for a circulating water pump includes a return water tank, a circulating pump, and an electric cylinder. An injection pipe is connected through the top of the return water tank, and an installation mechanism is provided at the bottom of the return water tank. This installation mechanism positions two sets of circulating pumps of the same size and connects them to the bottom of the return water tank. The connection between the circulating pumps and the bottom of the return water tank is adjusted according to the operating requirements of the circulating pumps. A positioning mechanism is provided on the back of the return water tank, which adjusts the positioning height according to the size and liquid volume of the return water tank to accommodate different specifications of return water tanks. An electric cylinder is connected to the bottom of the return water tank, and the output end of the electric cylinder is connected to the outside of the circulating pump.
[0006] Preferably, the installation mechanism includes a side bracket, positioning holes, connecting rods, a support plate, a circulation pump, and a tension spring. The side brackets are symmetrically arranged on both sides of the return water tank. Positioning holes are equally spaced on the outer side of the side brackets. The top end of the connecting rod is connected inside the side brackets. The connecting rods are symmetrically arranged on both sides of the support plate. A circulation pump is located directly above the support plate. The input end of the circulation pump is connected to the bottom end of the return water tank. A tension spring is located inside the side brackets. The support plate is located directly below the return water tank.
[0007] Preferably, the side bracket is connected to symmetrically arranged connecting rods through positioning holes that are equally spaced on the outer side.
[0008] Preferably, the side bracket is connected to the top of the connecting rod via an internally provided tension spring.
[0009] Preferably, the positioning mechanism includes a transverse lever arm, a sleeve block, a guide groove, a nut, and a threaded rod. A sleeve block is welded to one side of the transverse lever arm, and a threaded rod is connected through the outer side of the sleeve block. The threaded rod is welded inside the guide groove, and a nut is threadedly connected to the outer side of the threaded rod.
[0010] Preferably, the return water tank is connected to the outer side of the sleeve block through symmetrically arranged guide grooves.
[0011] Preferably, the guide groove is connected to the sleeve block through an internally threaded rod.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. The top of one or two circulating pumps is positioned by an electric cylinder, which lifts the circulating pump. This eliminates the need to place a lot of wooden blocks and bricks under the mounting frame, allowing the circulating pump to move up and down freely. It can accommodate various sizes of return water tank connection ports. The pump can be raised and lowered by simply turning the handle, greatly reducing the operator's workload.
[0014] 2. Multiple boilers can be connected in parallel to form a single drainage or water replenishment system, saving investment costs. Each module is independent of the others, making installation, assembly, maintenance, and replacement convenient. If a single module malfunctions during the heating season, adjustments can be made promptly. Multiple sets of circulating pumps can simultaneously replenish water to multiple boilers, or replenish water to one or several boilers individually by adjusting the opening and closing of the regulating valves.

[0022] 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.
[0023] like Figures 1 to 5 As shown, a circulating water pump adjustable installation structure includes a return water tank 1, a circulating pump 9, and an electric cylinder 16. An injection pipe 3 is connected through the top of the return water tank 1, and an installation mechanism 8 is provided at the bottom of the return water tank 1. The installation mechanism 8 positions two sets of circulating pumps 9 of the same size and connects them to the bottom of the return water tank 1. Based on the operating requirements of the circulating pumps 9, the connection between the circulating pumps 9 and the bottom of the return water tank 1 is established. A positioning mechanism 10 is provided on the back of the return water tank 1. The positioning mechanism 10 adjusts the positioning height according to the size and liquid volume of the return water tank 1, thereby accommodating the positioning of return water tanks 1 of different specifications. The bottom of the return water tank 1 is connected to the electric cylinder 16, and the output end of the electric cylinder 16 is connected to the outside of the circulating pump 9.
[0024] In this embodiment, the installation mechanism 8 includes a side bracket 4, positioning holes 5, connecting rods 6, a support plate 7, a circulation pump 9, and a tension spring 15. The side brackets 4 are symmetrically arranged on both sides of the return water tank 1. Positioning holes 5 are equally spaced on the outer side of the side brackets 4. The top end of the connecting rods 6 is connected inside the side brackets 4. The connecting rods 6 are symmetrically arranged on both sides of the support plate 7. The circulation pump 9 is arranged directly above the support plate 7. The input end of the circulation pump 9 is connected to the bottom end of the return water tank 1. The tension spring 15 is arranged inside the side brackets 4. The support plate 7 is arranged directly below the return water tank 1.
[0025] In this embodiment, the side bracket 4 is connected to the symmetrically arranged connecting rods 6 through positioning holes 5 opened at equal intervals on the outer side. The positioning holes 5 are used to position and lock the connecting rods 6 and the outer side of the side bracket 4.
[0026] In this embodiment, the side bracket 4 is connected to the top end of the connecting rod 6 via an internal tension spring 15. The tension spring 15 connects the top end of the connecting rod 6 to prevent the connecting rod 6 from falling during the lifting and lowering process.
[0027] In this embodiment, the positioning mechanism 10 includes a transverse lever arm 2, a sleeve block 11, a guide groove 12, a nut 13, and a threaded rod 14. The sleeve block 11 is welded to one side of the transverse lever arm 2, and the threaded rod 14 is connected through the outer side of the sleeve block 11. The threaded rod 14 is welded inside the guide groove 12, and the nut 13 is threadedly connected to the outer side of the threaded rod 14.
[0028] In this embodiment, the return water tank 1 is connected to the outside of the sleeve block 11 through symmetrically arranged guide grooves 12, and the guide grooves 12 are used to position and assemble the outside of the sleeve block 11.
[0029] In this embodiment, the guide groove 12 is connected to the sleeve block 11 through an internally provided threaded rod 14. The threaded rod 14 guides the sleeve block 11 inside the sleeve block 11 and adjusts the height of the sleeve block 11.
[0030] In practical applications, this type of adjustable installation structure for circulating water pumps includes the following tasks:
[0031] Step 1: The operator first selects the appropriate size of return water tank 1 according to the number of boilers and circulation requirements. The operator moves the sleeve block 11 to the outside of the threaded rod 14 by pulling it. The sleeve block 11 is positioned on one side of the transverse lever arm 2. The position of the transverse lever arm 2 is then adjusted. At the same time, the nut 13 is rotated on the outside of the threaded rod 14. The upper and lower sides of the sleeve block 11 are positioned by the symmetrically arranged nuts 13. The transverse lever arm 2 is then fitted to the wall by the symmetrically or asymmetrically arranged transverse lever arm 2. Finally, the transverse lever arm 2 and the wall are locked by the expansion bolts.
[0032] Step 2: Then, install the circulation pump 9 on the outside of the support plate 7. At the same time, use the electric cylinder 16 to connect one or two sets of circulation pumps 9. Use the electric cylinder 16 to drive the circulation pump 9 to rise vertically, thereby moving the circulation pump 9 and the support plate 7 vertically upward. This causes the connecting rods 6 on both sides of the support plate 7 to move outside the side bracket 4, so that the input end of the circulation pump 9 is connected to the bottom end of the return water tank 1. At the same time, bolts are used to connect the circulation pump 9 and the return water tank 1.
[0033] Step 3: Then insert the screw into the positioning hole 5 to lock the connecting rod 6 to the outside of the side bracket 4. The tension spring 15 at the top of the connecting rod 6 will be compressed according to the height of the connecting rod 6 to prevent the connecting rod 6 from falling during the lifting process. Then, the hot water inside the boiler is injected into the return water tank 1, and the hot water is circulated through the circulation pump 9 at the bottom.
[0034] Step 4: During use, based on the number of boilers in operation or the amount of hot water, two sets of circulating pumps 9 are symmetrically set up so that the top input end of the circulating pump 9 is connected to the bottom end of the return water tank 1, thereby circulating or recovering heat through the liquid inside the return water tank 1, and extracting the liquid through the circulating pump 9, thereby controlling the amount extracted and discharged.
[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
