Description

Technical Field

[0001] The invention relates to the technical field of heat storage heating, and in particular to a solar electric boiler water heat storage system for heating. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] At present, the input energy of boilers in the market is still mainly fuel, which results in huge consumption of fuel in actual use, often consuming most of the material and financial resources in the factory processing process. Moreover, when a large amount of fuel is used in the boiler, it is also very easy to pollute the surrounding air environment.

[0004] With the continuous development of the times, the society's utilization of solar energy is increasing day by day. However, there is no complete system in this field to combine solar energy with boilers to reduce the boiler's dependence on fuel, so as to reduce the consumption of financial and material resources to a certain extent and reduce pollution to the surrounding air environment.

[0005] In addition, it should be emphasized that traditional boilers also have some disadvantages in actual use, and these disadvantages have directly affected the inability of traditional boilers to meet the current high-standard usage requirements in the field of thermal storage heating. Traditional boilers discharge steam during use and only rely on the continuous increase in water temperature to generate steam. This method is too backward and cannot speed up the output of steam.

[0006] Therefore, it is very important to propose a new and complete solar electric boiler water heat storage system for heating in the art to solve the above problems. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide a solar electric boiler water heat storage system for heating, so as to solve the problem that traditional boilers in the prior art are overly dependent on fuel, resulting in excessive waste of financial and material resources, and further solve the problem of slow steam discharge speed of the boiler during use.

[0008] The present invention is achieved through the following technical solutions:

[0009] A solar electric boiler water heat storage system for heating, comprising a boiler body and an exhaust pipe connected to and arranged on the top of the boiler body, a heat storage component for absorbing solar energy and preventing the loss of solar energy heat, and a regulating component for accelerating steam output;

[0010] The heat storage assembly includes a solar collector, a polystyrene board and a heat preservation cotton pad arranged on both sides of the bottom of the polystyrene board, and the two sides of the bottom of the solar collector are provided with concave slide grooves for sliding and storing the polystyrene board. The polystyrene board is detachably fixed to the top of the solar collector by a fixing piece, and when the polystyrene board is fixed to the top of the solar collector, the heat preservation cotton pad can insulate both sides of the solar collector;

[0011] One side of the solar collector is connected to a water storage tank for storing heated water through a water pump, and one side of the water storage tank is connected to the boiler body through a water pump;

[0012] The adjustment components are provided in two groups and are symmetrically arranged on both sides of the boiler body. The adjustment components include a fan, a first electric push rod, an L-shaped baffle plate arranged on the output end of the first electric push rod, and a waterproof shell arranged on both sides of the boiler body. The waterproof shell is a hollow structure with one side open. The fan is arranged inside the waterproof shell. The waterproof shell is provided with a storage groove block that can accommodate the L-shaped baffle plate. The first electric push rod is extended to drive the L-shaped baffle plate to extend out of the storage groove block, and the interlaced area between the L-shaped baffle plate and the storage groove block can form a blocking surface for the opening of the waterproof shell.

[0013] Furthermore, it also includes a self-protection component to prevent the boiler body from being damaged due to excessive gas pressure inside the boiler body.

[0014] Furthermore, the self-protection component includes an air pressure sensor arranged inside the boiler body, a pressure relief pipe connected to one side of the boiler body, and an electric valve arranged inside the pressure relief pipe.

[0015] Furthermore, the electric valve includes a second electric push rod obliquely arranged inside the pressure relief pipe and a telescopic door arranged inside the pressure relief pipe.

[0016] Furthermore, the telescopic door includes a telescopic sleeve arranged inside the pressure relief pipe through a hinge, a return spring arranged inside the telescopic sleeve and a telescopic plate connected to one end of the return spring, the telescopic sleeve is a hollow structure with one end open, and the telescopic plate can freely extend and retract inside the telescopic sleeve under the action of the elastic force of the return spring, and the top end of the telescopic sleeve is fixedly connected to the output end of the second electric push rod.

[0017] Furthermore, the fixing part includes an insert plate arranged on the front and rear sides of the polystyrene board and a slot base arranged on the front and rear sides of the top of the solar collector. The slot base is a hollow structure with an opening on the top. The insert plate is inserted into the interior of the slot base through the opening to fix the polystyrene board to the top of the solar collector.

[0018] Furthermore, the surface of the plug board is provided with elastic limit keys, the surface of the slot base is provided with limit holes, and the plug board is inserted into the interior of the slot base until the elastic limit keys are engaged with the limit holes to fix the plug board inside the slot base.

[0019] The beneficial effects of the present invention are:

[0020] 1. The solar electric boiler water heat storage system for heating, through the coordinated use of solar collectors, polystyrene boards, thermal insulation pads, water storage tanks and water pumps, can first use the solar collectors to absorb solar heat and heat the running water. When the weather is cold, the polystyrene boards can be used to insulate the top of the solar collectors, and then the thermal insulation pads can be used to insulate the two sides of the solar collectors to prevent heat loss. When the hot water is heated, it is pumped into the water storage tank and stored in the water storage tank. When professionals need to use the boiler body for steam output, the hot water heated in the water storage tank is directly guided and pumped into the boiler body for further hot water heating and steam output. Compared with the traditional boiler for heating running water, the technical solution of the present application effectively uses solar thermal energy to heat the hot water first, thereby reducing the energy required to directly use the boiler to heat the hot water to generate hot steam, thereby avoiding the waste of financial and material resources to a certain extent.

[0021] 2. The solar electric boiler water heat storage system for heating, through the coordinated use of the fan, the first electric push rod, the L-shaped baffle and the waterproof shell, when the boiler body heats the hot water to generate hot steam, the first electric push rod can be contracted and drive the L-shaped baffle to move, so that the opening on one side of the waterproof shell is opened. At this time, the fan starts to work, forming a gas flow on the surface of the hot water, thereby effectively accelerating the generation of hot steam, thereby satisfying the function of efficiently generating hot steam for use in the heating system. Compared with the traditional boiler heating to generate hot steam, the technical solution of the present application effectively improves the generation rate of hot steam.

[0022] In short, the technical solution of the present application, through a coherent and compact structure, effectively solves the problem of excessive reliance on fuel by traditional boilers to generate hot steam, which leads to excessive waste of financial and material resources, and further solves the problem of slow steam discharge during boiler use.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0037] See also Figure 1-7 The present invention provides a technical solution: a solar electric boiler water heat storage system for heating, comprising a boiler body 4 and an exhaust pipe connected to the top of the boiler body 4, and also comprising a heat storage component 1 for absorbing solar energy and preventing the loss of solar energy heat and a regulating component 8 for accelerating steam output;

[0038] The heat storage component 1 includes a solar collector 101, a polystyrene board 103 and a heat preservation cotton pad 102 arranged on both sides of the bottom of the polystyrene board 103. Concave slide grooves for sliding and storing the polystyrene board 103 are arranged on both sides of the bottom of the solar collector 101. The polystyrene board 103 is detachably fixed to the top of the solar collector 101 by a fixing member 2. When the polystyrene board 103 is fixed to the top of the solar collector 101, the heat preservation cotton pad 102 can insulate both sides of the solar collector 101. When the weather conditions are suitable for the solar collector to work, the polystyrene board can be inserted into the inner side of the concave chute at the bottom of the solar collector for storage. When the solar collector has absorbed the sun's heat and the weather becomes cold, the polystyrene board can be taken out from the inner side of the concave chute and further fixed to the top of the solar collector using the installation assembly. In addition, the thermal insulation pad can cover both sides of the solar collector, thereby achieving the purpose of thermal insulation of the solar collector as much as possible and avoiding excessive heat loss.

[0039] One side of the solar collector 101 is connected to a water storage tank 3 for storing heated water through a water pump. One side of the water storage tank 3 is connected to the boiler body 4 through a water pump. The water pump model mentioned in this application may be a JTP-1800 water pump. When the water storage inside the solar collector is heated, the heated water can be pumped to the water storage tank for storage through the water pump.

[0040] The adjustment assembly 8 is provided with two groups, and is symmetrically arranged on both sides of the boiler body 4. The adjustment assembly 8 includes a fan 802, a first electric push rod 803, an L-shaped baffle 801 arranged on the output end of the first electric push rod 803, and a waterproof shell 804 arranged on both sides of the boiler body 4. The waterproof shell 804 is a hollow structure with one side open. The fan 802 is arranged inside the waterproof shell 804. The waterproof shell 804 is provided with a storage groove block that can accommodate the L-shaped baffle 801. The first electric push rod 803 extends to drive the L-shaped baffle 801 to extend out of the storage groove block, and the staggered area between the L-shaped baffle 801 and the storage groove block can constitute a sealing surface for the opening of the waterproof shell 804. The present application The model of the first electric push rod 803 and the second electric push rod can be JU-TGE electric push rod. When the boiler body heats the hot water to generate hot steam, the first electric push rod can begin to shrink and drive the L-shaped baffle to move until the L-shaped baffle is shrunk to the inside of the storage slot block, so that the opening on one side of the waterproof shell is open. At this time, the fan starts to work, forming a gas flow on the surface of the hot water, thereby effectively accelerating the generation of hot steam, thereby satisfying the function of efficiently generating hot steam for use by the heating system. When there is no need to speed up the steam output, the first electric push rod is extended, and the L-shaped baffle is pulled out of the storage slot block to form a blockage for the opening of the waterproof shell. At this time, the fan stops working.

[0041] The working process of this device is as follows: first, the electrical equipment is powered by an external power supply through a wire, and water is pumped into the interior of the solar collector to be heated using solar thermal energy. After the heating is completed, the hot water can be pumped into a water storage tank for storage, and the remaining water flow is pumped into the interior of the solar collector for heating. At this time, when the boiler body needs to work to generate hot steam, the hot water in the water storage tank can be pumped into the interior of the boiler body through a water pump (the boiler is a prior art, and the hot water can be further heated by fuel to generate hot steam, which is discharged through an exhaust pipe).

[0042] In addition, it should be emphasized that the technical solution of the present application takes environmental issues into consideration, abolishes traditional rock wool insulation, and adopts special expanded perlite as external insulation as the internal thermal insulation layer of the water tank. It is dust-free, free of flying catkins, and will not cause secondary pollution. An adjustment component is arranged inside the water tank. The adjustment component includes a heating wire arranged inside the water tank for heating the stored water and a sliding rheostat, a control button and a power plug connected to the heating wire through a wire. The surface of the heating wire is brushed with metal zirconium. The heating wire is made of iron-chromium-aluminum alloy material with zirconium and other components added. Through repeated practice, the alloy heating wire disclosed in the present application is obtained. At present, the effective life of the heating wire has reached the level of years without damage. This technical feature specifically solves the technical problem that traditional heating wires are easily damaged. When the stored water pumped into the water tank drops in temperature due to heat loss, an external power supply can be connected through the power plug, and the control button can be used The sliding rheostat is controlled to adjust the output power of the heating wire so as to heat the stored water to the original required temperature again. The model of the sliding rheostat can be BC-100W sliding rheostat. In addition, a safety component is provided to prevent the heating wire from being damaged by short circuit and a monitoring component for real-time monitoring of the water temperature inside the water tank. The safety component includes a PLC controller and a power-off protector connected in series with the heating wire. When the heating wire is short-circuited, the PLC controller immediately captures the short-circuit signal and sends an instruction command to the power-off protector. The power-off protector starts working immediately and performs power-off protection on the entire device to avoid the device being in operation when the heating wire is short-circuited. The monitoring component includes a temperature sensor arranged inside the water tank and a display screen arranged on the surface of the water tank for signal transmission with the temperature sensor through a connecting line. The model of the temperature sensor can be a PT100 WZP temperature sensor. The temperature sensor monitors the water temperature inside the water tank in real time and displays this temperature information through a display screen so that the staff can grasp the water temperature inside the water tank at any time.

[0043] The present invention also includes a self-protection component 5 for preventing the boiler body 4 from being damaged due to excessive gas pressure inside the boiler body 4.

[0044] In the present invention: the self-protection component 5 includes an air pressure sensor 502 arranged inside the boiler body 4, a pressure relief pipe 501 connected to one side of the boiler body 4 and an electric valve 7 arranged inside the pressure relief pipe 501. The model of the air pressure sensor can be an MI K-P300 air pressure sensor. When the air pressure sensor detects that the air pressure inside the boiler body is too high, the electric valve 7 can be used to allow the pressure relief pipe to discharge gas smoothly to reduce the gas pressure inside the boiler body.

[0045] In the present invention, the electric valve 7 includes a second electric push rod 701 obliquely arranged inside the pressure relief pipe 501 and a telescopic door 6 arranged inside the pressure relief pipe 501. The telescopic door is opened or closed by the extension and retraction of the second electric push rod 701 to control the closure or unobstructedness of the pressure relief pipe.

[0046] In the present invention, the telescopic door 6 includes a telescopic cover plate 602 arranged inside the pressure relief pipe 501 through a hinge, a reset spring 603 arranged inside the telescopic cover plate 602, and a telescopic plate 601 connected to one end of the reset spring 603. The telescopic cover plate 602 is a hollow structure with an open end. The telescopic plate 601 can be freely telescopic inside the telescopic cover plate 602 under the action of the elastic force of the reset spring. The top end of the telescopic cover plate 602 is fixedly connected to the output end of the second electric push rod 701. When the second electric push rod is extended, the telescopic cover plate 602 is extended. The retractable sleeve can be in a perpendicular shape to the pressure relief pipe, and the telescopic plate is arranged inside the telescopic sleeve in a telescopically adjustable manner by a reset spring, so as to avoid the telescopic plate from getting stuck during the telescopic process of the telescopic sleeve. When the second electric push rod is shortened, the telescopic sleeve is in a dumping shape, so that the telescopic plate extends together under the elastic force of the reset spring. At this time, the telescopic sleeve and the telescopic plate do not form a sealing work for the opening of the pressure relief pipe, and the gas inside the boiler body can be discharged smoothly through the pressure relief pipe to reduce the gas pressure inside the boiler body.

[0047] In the present invention: the fixing member 2 includes an insert plate 201 arranged on the front and rear sides of the polystyrene board 103 and a slot base 202 arranged on the front and rear sides of the top of the solar collector 101. The slot base 202 is a hollow structure with an opening on the top. The insert plate 201 is inserted into the interior of the slot base 202 through the opening to form the polystyrene board 103 fixed to the top of the solar collector 101. The insert plate is inserted into the interior of the slot base through the opening to form the polystyrene board fixed to the top of the solar collector. After the polystyrene board is pulled out, the insert plate can be inserted into the inner side of the slot base to achieve the purpose of fixing the polystyrene board to the top of the solar collector.

[0048] In the present invention: elastic limit keys are provided on the surface of the plug board 201, and limit holes are provided on the surface of the slot base 202. The plug board 201 is inserted into the interior of the slot base 202 until the elastic limit key and the limit hole are engaged with each other to fix the plug board 201 inside the slot base 202. When the plug board is inserted into the interior of the slot base, the elastic limit key can be engaged with the inner side of the limit hole to fix the plug board inside the slot base to avoid the plug board from shaking or loosening inside the slot base due to external factors. It should be emphasized here that the elastic limit key mentioned in the present application has been disclosed in the authorized and disclosed utility model case "A device for building construction simulation based on BIM" (CN208281424U), and the structural principle of the elastic limit key has been disclosed, so this application will not repeat it.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
