Shock-isolated composite energy water heater

technical field

The invention relates to a water heater, in particular to a shock-isolation composite energy water heater.

Background technique

Existing water heaters include solar water heaters, electric energy water heaters and earthen stove water heaters etc. according to the difference of heat sources. The earth stove water heater is a water heater that uses the heat emitted by the earth stove to heat the water, and has the advantage of not consuming electricity, gas and other energy sources. A kind of soil stove water heater is disclosed in the patent document whose Chinese patent number is 2009201265540, the date of authorization announcement is December 16, 2009, and the name is called "earth stove water heater". The earth stove water heater in this patent document includes a water tank and a heating coil for absorbing the heat of the earth stove. The water inlet end of the heating coil is connected with the water tank, and the water outlet end of the heating coil is provided with a water outlet tap and an exhaust pipe. The exhaust pipe is connected with the water tank. When in use, bury the heating coil in the earthen stove, add water to the water tank, and when the faucet is turned on, the water flows from the water tank to the heating coil and then to the faucet. When the water flows through the heating coil, it is heated by the heat generated by the earthen stove. The generated water vapor is discharged back into the water tank to be condensed so as to heat the water in the water tank. The earth stove water heater can obtain free hot water in the vast rural areas where the earth stove is used, and makes full use of the heat released by the earth stove.

The existing earthen stove water heater has the following disadvantages: when heating, countercurrent will be generated, resulting in poor fluidity of water, and poor fluidity will affect the heat exchange effect. In addition, the rural areas are in the form of one house per household, and the roofs bathed by the sun in a large area are not fully utilized, and the earth stove water heaters cannot utilize the roofs of this form.

Although solar water heaters can be installed on the roof and use solar energy to heat hot water, they cannot use the energy of the earthen stove to light a fire. Therefore, existing water heaters have the disadvantage of a single heat source, and cannot ensure sufficient hot water supply in an economical manner; the vibration of the water tank caused by water circulation will be transmitted to the outside, so the shock isolation effect of the water tank is poor.

Contents of the invention

The invention provides a shock-isolated composite energy water heater capable of recycling the heat released by earthen stoves and the sun and having good heat exchange and shock-isolation effects. way to ensure that there is an adequate supply of hot water and vibration is a big problem.

The above technical problems are solved through the following technical solutions: a shock-isolated composite energy water heater, including an earthen stove hot water circulation circuit composed of a water tank and a heating coil for absorbing the heat of the earthen stove, and a solar collector and an insulation The shock mount, the water tank and the solar heat collector form a solar hot water circulation loop, and a circulating water pump is arranged in the hot water circulation loop of the earthen stove. The shock isolation frame includes a frame body and rubber support feet supporting the frame body. The bottom surface of the rubber supporting foot is provided with a liquid storage chamber and an isolation plate located in the liquid storage chamber, and the isolation plate divides the liquid storage chamber into an upper liquid storage chamber and a lower liquid storage chamber, and the isolation plate is provided with The main damping channel connecting the upper liquid storage chamber and the lower liquid storage chamber, the main damping channel is provided with an energy-absorbing plate, and the energy-absorbing plate is pierced with a damping rod that can slide in the up and down direction, and the damping rod A branch damping channel is provided, and the lower end of the lower liquid storage chamber is provided with a bowl-shaped rubber cover arched toward the interior of the lower liquid storage chamber, and the circulating water pump and the water tank are connected to the frame body.

When in use, the water tank and the circulating water pump are supported by the shock-isolating frame, and the shock-isolating frame is connected with other equipment through rubber support feet. The liquid storage chamber is filled with damping liquid, cold water is added to the water tank, and the heating coil is buried in the soil stove. 1. The solar collector is installed on the roof, and the water in the water tank circulates in the solar hot water circulation loop. While being heated by absorbing the energy of the sun through the solar collector, it also circulates in the earth stove hot water circulation loop. It is heated by absorbing the heat released from the earthen stove by the heating coil. Therefore, as long as the earth stove lights a fire or has the sun, the water in the water tank can be heated, which overcomes the single deficiency of the heat source and does not need to spend money to purchase the obtained energy, and the economy is good. The circulating water pump can ensure that the water in the hot water circulation circuit of the earthen stove can flow smoothly in one direction, the flow direction is single and smooth, and the heat absorption effect on the earthen stove is good. When the vibration generated by the water tank and the circulating water pump is transmitted to the rubber support feet to cause the deformation of the liquid storage chamber, the deformation of the liquid storage chamber will drive the damping fluid in it to flow back and forth between the upper liquid storage chamber and the lower liquid storage chamber. And damping rod shaking, damping fluid flow and energy absorbing plate and damping rod shaking process will convert the vibration energy into heat energy and consume it. If the vibration is too small to cause the deformation of the liquid storage chamber, only the damping fluid shakes at this time. When the damping fluid shakes, the damping rod shakes and absorbs energy. Setting the damping rod can improve the absorption of high-frequency and low-amplitude vibrations, making this The invention can not only absorb high-amplitude vibration energy, but also absorb low-amplitude vibration energy, so the shock isolation effect is better.

Preferably, the damping rod extends up and down, both axial ends of the damping rod protrude from the energy-absorbing plate, and both axial end surfaces of the damping rod are spherical surfaces. It can make the damping fluid drive the damping rod to run in the up and down direction to absorb energy when it receives the vibration in the non-up and down direction. The energy absorption effect is good.

It can also absorb energy in response to vibration in the horizontal direction, and the reliability of absorbing vibration energy is better.

Preferably, a skeleton is provided inside the rubber body, and the skeleton is a coil spring that expands and contracts in the up and down direction. It can not only improve the rigidity of the shock-isolation seat to meet the support requirements, but also further improve the absorption effect of high-amplitude vibration.

Preferably, the liquid storage cavity is located inside the space surrounded by the skeleton. The skeleton can also play a guiding role in the deformation of the liquid storage chamber, so that the liquid storage chamber can be reliably denatured to drive the damping fluid to flow and realize energy absorption.

The present invention also includes an oil replenishing mechanism. The circulating water pump includes a pump casing, a pump shaft and a bearing that rotatably connects the pump shaft to the pump casing. The pump casing is provided with an oil filling hole for refueling the bearing. The oil replenishing mechanism It includes an oil storage tank, an oil outlet channel, a membrane rupture rod and a corrosive liquid storage tank. One end of the oil outlet channel is provided with an oil inlet bucket, and the other end is provided with a fuel nozzle connected to the oil filling hole. The tank includes at least two cavities that are sheathed in sequence and fixed together. The lower side wall of the cavities is provided with an oil outlet, and the oil outlet is sealed and connected with a sealing film. The oil inlet bucket is located on the Below the oil outlet, the membrane rupture rod extends vertically and is connected in the oil inlet bucket, the membrane rupture rod and the oil outlets of all the cavities are located on the same vertical line, The corrosive liquid storage tank is provided with a regular rot-permeable buoy, and the regular rot-permeable buoy includes a corrosion-resistant shell with an open lower end and a number of corroded holes that can be corroded by the corrosive liquid in the corrosive liquid storage tank for a set period of time. A partition, the partition divides the shell into several floating chambers, the number of the floating chambers is equal to the number of the cavities, the partitions are distributed along the up and down direction, and the oil storage tank passes through the buoy Floating on the corrosive liquid in the corrosive liquid storage tank, each of the floating chambers can independently float the oil storage tank; every time the corrosive liquid in the corrosive liquid storage tank corrodes a floating chamber, it will cause When the oil storage tank is lowered once, the membrane rupture rod can only puncture the sealing membrane on one cavity. It can automatically and regularly replenish lubricating oil for the bearings of the circulating water pump.

Preferably, the corrosive liquid storage tank is provided with a wave-dissipating plate that can float on the corrosive liquid in the corrosive liquid storage tank, and the shell can pass through the wave-dissipating plate in a vertical direction. During use, when the corrosive liquid storage tank is vibrated, the corrosive liquid will slosh. The waves generated by the corrosive liquid slosh will cause the regular decay buoy to rise and fall. If the lifting phenomenon is too large, the membrane rupture rod will puncture the seal. The phenomenon that the lubricating oil flows out before the set time is not reached, that is, the malfunction caused by vibration. After installing the wave-dissipating plate, it can effectively reduce the lifting range of the periodic decay buoy caused by vibration, and avoid malfunction caused by vibration.

Preferably, the peripheral surface of the wave-dissipating plate abuts against the side wall of the corrosive liquid storage tank. The best wave dissipation effect can be achieved, so that only the corrosive liquid storage tank does not produce roll, and the periodic rotten type buoy basically does not produce lifting relative to the corrosive liquid storage tank.
