Description

Technical Field

[0001] The invention relates to the technical field of water source heat pumps, in particular to a mine water combined with a water source heat pump heating circulation system. Background Art

[0002] A water source heat pump is an environmentally friendly heating and cooling system that uses water bodies such as groundwater, lakes, rivers or surface water as a thermal energy source. It uses the thermal energy in the water to heat or lower the temperature of the building to provide a comfortable indoor environment. Water source heat pump systems are generally divided into two types: open-loop systems and closed-loop systems. The open-loop system uses groundwater or surface water, pumps water to the building through pipes, and uses the thermal energy in the water for heat exchange. The closed-loop system achieves heat exchange through water circulating in a loop buried underground, without direct contact with groundwater.

[0003] The water source heat pump combined with mine water uses an open-loop system. Since the mine water is pumped upward through a long pipe, the heat energy of the well water will be lost during the transportation process, causing the well water temperature to drop, which in turn leads to a decrease in the efficiency of heat exchange. Summary of the invention

[0004] The object of the present invention is to provide a mine water combined with a water source heat pump heating circulation system to solve the above problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A mine water combined with water source heat pump heating circulation system, comprising;

[0006] A groundwater source heat pump, to which an auxiliary heating device and an anti-blocking water inlet device are connected;

[0007] The bottom of the groundwater source heat pump is provided with a water source heat pump inlet pipe and a water source heat pump drain pipe. The end of the water source heat pump inlet pipe away from the groundwater source heat pump is connected to the auxiliary heating device. The anti-blocking water inlet device is connected to the anti-blocking water inlet device. The anti-blocking water inlet device is inserted into the mine to extract the water source inside the mine. Then the water source passes through the auxiliary heating device to assist in heating the mine water with the help of environmental heat energy, so that the mine water can obtain more heat energy through the heat exchanger after entering the groundwater source heat pump.

[0008] Preferably, the auxiliary heating device includes a heating pipe, a heat preservation pipe, a connecting pipe A, a base guard plate, a foam insulation layer, a connecting plate and a connecting plate;

One end of the heating pipe is sleeved on the outside of the water source heat pump inlet pipe and is fixed with the water source heat pump inlet pipe by thread, and is connected by thread, so as to facilitate the rapid installation of the heating pipe and the water source heat pump inlet pipe, and can also be disassembled during maintenance, and the connection between the heating pipe and the water source heat pump inlet pipe has a sealing ring to enhance the sealing performance, and the sealing by the sealing ring can prevent water leakage at the connection, and the other end of the heating pipe is sleeved on the outside of the connecting pipe A and is fixed with the connecting pipe A by thread, and is connected by thread, so as to facilitate the rapid installation of the connecting pipe A and the heating pipe, and the connection between the heating pipe and the connecting pipe A has a sealing ring to enhance the sealing performance, and the sealing by the sealing ring can prevent water leakage at the connection;

[0010] The base guard plate is located at the bottom of the insulation pipe, and the top of the base guard plate has two integrally fixed longitudinal extension plates. The foam insulation layer is located between the two longitudinal extension plates. The foam insulation layer is limited and positioned by the limit plate. When installing the foam insulation layer, the foam insulation layer is always kept in the center position to avoid deviation in the installation position. The foam insulation layer is glued and fixed to the base guard plate by glue. An arc groove is opened on the top of the foam insulation layer. The heating pipe is sunken in the arc groove on the top of the foam insulation layer. The concave design makes the heating pipe sunken in a fixed position.

[0011] There are two connecting plates, and both sides of the base guard plate are fixed integrally with the two connecting plates respectively. The solar refraction plate is located on the inner side of the connecting plate, and the solar refraction plate is glued and fixed to the connecting plate. The connecting plate and the solar refraction plate are both arc-shaped, and the axial intersection of the solar refraction plate is located on the outer wall of the heating tube. When the sun shines on the solar refraction plate, the sunlight is reflected and focused on the heating tube through the solar refraction plate. The heating tube is heated by sunlight, so that the temperature of the well water is increased when passing through the heating tube, thereby improving the efficiency of heat exchange.

[0012] Preferably, the heating tube is made of stainless steel. When the sunlight cup is focused and irradiated on the heating tube, the heating tube heats up quickly. The stainless steel heating tube has high thermal conductivity and can quickly conduct heat to the well water inside. The insulation tube is made of transparent glass. The insulation tube is sleeved on the outside of the heating tube. The sunlight refracted by the solar refraction plate can penetrate the insulation tube to avoid affecting the heat absorption of the heating tube. The heating tube can be insulated by the insulation tube to reduce the heat energy loss of the heating tube. The rubber sealing sleeves at both ends of the insulation tube wrap around the contour of the heating tube and are sealed and limited at both ends.

[0013] Preferably, the anti-blocking water inlet device includes a water pump, a connecting pipe B, a connecting pipe C, a water inlet joint, and a stirring shaft;

The bottom inner wall of the connecting pipe B is provided with an internal thread, and the top of the connecting pipe C is embedded in the inside of the connecting pipe B and is threadedly connected to the connecting pipe B, and is connected by a threaded manner, so as to facilitate the quick installation of the connecting pipe C and the connecting pipe B;

When the water enters the inside of the water inlet joint, it is filtered through the water inlet filter, thereby reducing impurities in the extracted water source, and each water inlet filter has a plurality of baffles on the outside, the baffles are arc-shaped, and there is a spacing between every two baffles. One end of the baffle is welded and fixed to the outside of the water inlet filter, and when larger debris is approached to the water inlet joint by the suction of the water pump, it is blocked by the baffle to prevent the larger debris from being adsorbed on the water inlet filter and affecting the water inlet efficiency;

[0016] Preferably, the connecting pipe C has a stirring shaft inside, and the outer wall of the stirring shaft near the bottom has a plurality of blades, and the plurality of blades are distributed in a ring on the outer wall of the stirring shaft, and the blades are connected and fixed to the stirring shaft by welding. The connecting pipe B has a spiral plate on the top of the blade on the outside, and the spiral plate is spirally shaped, and is fixed to the outer wall of the stirring shaft by welding. When well water enters the connecting pipe C, since the spiral plate is spirally shaped, the upward fluidity of the water flow will drive the spiral plate to rotate, and when the spiral plate rotates, it will synchronously drive the stirring shaft and the blades to rotate. The water flow pushed by the rotation of the blades will flush down the impurities adsorbed on the water inlet filter, so as to avoid blockage caused by impurities adsorbed on the water inlet filter.

[0017] Preferably, the bottom of the water inlet joint has a positioning ring, the outer side of the positioning ring is buckled on the bottom of the water inlet joint, and there are multiple balls between the positioning ring and the water inlet joint, so that the positioning ring can be rotatably connected with the water inlet joint, the interior of the stirring shaft is a hollow structure, and the top of the positioning ring has an integrally fixed connecting shaft, and the bottom of the stirring shaft is sleeved on the outer side of the connecting shaft and is rotatably connected with it, so that the stirring shaft rotates due to the rotational force generated when the spiral plate rotates, and the smoothness of the rotation of the stirring shaft can be enhanced by the positioning ring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention uses an auxiliary heating device to perform auxiliary heating during the transportation of mine water to improve the heat exchange efficiency. The sun shines on the solar refraction plate, which reflects and focuses the sunlight on the heating tube. The heating tube is heated by sunlight, so that the temperature of the well water is increased when it passes through the heating tube, thereby improving the heat exchange efficiency.

[0020] 2. The present invention uses an anti-blocking water inlet device to prevent debris from clogging the water inlet pipe when extracting mine water, thereby extending the equipment maintenance cycle and saving costs. When the well water enters the interior of the connecting pipe C, the spiral plate is spiral-shaped, and the upward fluidity of the water flow will drive the spiral plate to rotate. When the spiral plate rotates, it will synchronously drive the stirring shaft and the blades to rotate. The water flow pushed by the rotating blades will flush down the impurities adsorbed on the water inlet filter screen, thereby preventing the impurities from being adsorbed on the water inlet filter screen and causing blockage.

The foam insulation layer 301 is glued and fixed to the base guard plate 300 with glue. An arc-shaped groove is opened on the top of the foam insulation layer 301. The heating pipe 200 is sunken in the arc-shaped groove on the top of the foam insulation layer 301. The concave design makes the heating pipe 200 sunken in a fixed position.

[0037] There are two connecting plates 302, and the two sides of the base guard plate 300 are fixed integrally with the two connecting plates 302 respectively. The solar refraction plate 303 is located on the inner side of the connecting plate 302. The solar refraction plate 303 is glued and fixed to the connecting plate 302. The connecting plate 302 and the solar refraction plate 303 are both arc-shaped. The axial intersection of the solar refraction plate 303 is located on the outer wall of the heating tube 200. When the sun shines on the solar refraction plate 303, the sunlight is reflected and focused on the heating tube 200 through the solar refraction plate 303.

[0041] Furthermore, the water inlet joint 502 is located at the bottom of the connecting pipe C501, and the water inlet joint 502 is fixed to the connecting pipe C501 by welding. The upper and lower ends of the water inlet joint 502 are provided with water inlet screens 503, and the water inlet screens 503 are connected and fixed to the water inlet joint 502 by welding. The water inlet joint 502 is placed in the wellhead, and the water pump 400 is started to generate suction so that the well water enters the interior of the water inlet joint 502. When the water enters the interior of the water inlet joint 502, it passes through the water inlet screen 503. Filtering is performed to reduce impurities in the extracted water source. A plurality of baffles 504 are provided on the outside of each water inlet filter 503. The baffles 504 are arc-shaped, and there is a spacing between each two baffles 504. One end of the baffle 504 is welded and fixed to the outside of the water inlet filter 503.

[0044] Working principle: the connecting pipe B500, the connecting pipe C501 and the water inlet joint 502 are extended into the wellhead, and the well water inside the connecting pipe B500 is extracted by the water pump 400 and transported upward to the inside of the water pump 400. When the water enters the inside of the water inlet joint 502, it is filtered through the water inlet filter 503, thereby reducing the impurities in the extracted water source. When larger debris is approached to the water inlet joint 502 by the suction force of the water pump 400, it is blocked by the blocking plate 504 to prevent the larger debris from being adsorbed on the water inlet filter 503 and affecting the water inlet efficiency. When the well water enters the inside of the connecting pipe C501, since the spiral plate 702 is spiral, the upward fluidity of the water flow will drive the spiral plate 702 to rotate. When the spiral plate 702 rotates, it will synchronously drive the stirring shaft 700 and the blade 701 to rotate. When the blade 701 rotates, the water flow pushed by the water flow will flush down the impurities adsorbed on the water inlet filter 503, thereby preventing the impurities from being adsorbed on the water inlet filter 503 and causing blockage.

[0045] Furthermore, when well water enters the heating tube 200 from the connecting pipe A202, when the sun shines on the solar refraction plate 303, the sunlight is reflected and focused on the heating tube 200 by the solar refraction plate 303, and the heating tube 200 is heated by sunlight, so that the temperature of the well water is increased when passing through the heating tube 200, thereby improving the efficiency of heat exchange.
