Description

Fish rainbow heater with water purification function

[Technical Field]

The utility model relates to a heater used in a fish pond and a fish tank, which particularly relates to a novel high-efficiency fish tank heater with a crystal ceramic thick film electric heating sheet (KMCH) as a heat source body, that is, a fish tank heater with a water purification function.

【Background technique】

In the background art, the best selling aquarium heating device on the market is a glass tube heating rod, and the manufacturing method or the structure thereof is to wind the heating wire around the ceramic skeleton, and then place the ceramic skeleton wrapped with the heating wire in the glass tube. One end of the ceramic skeleton and the bottom of the glass tube are padded with asbestos layer, and then filled with quartz sand, and the other end of the lead electrode is connected with the temperature control circuit, fixed and sealed. In order to prevent accidental cracking of the glass tube or rupture damage caused by external squeezing collision, some even put a metal tube on the outside of the glass tube. However, when the inner glass tube is accidentally broken, the electric heating wire wound on the ceramic skeleton is internally wound. Exposed, it is possible to contact the metal tube and cause leakage, which has certain safety hazards.

The shortcomings and disadvantages of this structure of the background art are:

1. The biggest drawback of the structure is that the quartz sand for filling must be pre-baked and ensured to be packaged in a relatively dry environment. Otherwise, the glass tube may burst due to the expansion of the hot air generated by the quartz sand during the heating process. The internal circuit is short-circuited, so the product has a high failure rate and a short service life.

2. The main component of the asbestos layer used in the traditional glass tube heating rod is magnesium silicate, which is an inorganic fiber material. It has good heat insulation and corrosion resistance, and is not easy to burn, but the biggest hazard of asbestos comes from its fiber. When these fine fibers are separated from each other and released, they can float in the air for a long time, and asbestos fibers that are inhaled into the human body can accumulate and adhere to human lungs for many years, causing lung diseases. When the workers are directly in contact with asbestos, the asbestos fibers can penetrate deep into the skin, causing hyperkeratosis of the skin, cell proliferation and the formation of giant cells, which produce the skin's "asbestos". Asbestos dust pollutes drinking water and food, and can also be absorbed into the blood by the stomach and deposited in multiple organs. Asbestos is carcinogenic and causes lung diseases, can cause chronic respiratory diseases; lung cancer, stomach cancer, colon cancer, mesothelioma, etc., so asbestos is recognized as an illegal substance in the international medical community. Quality, has been identified as a primary carcinogen by the International Cancer Research Center.

3. Traditional fish The heating rod is bulky and heavy. Generally, the heating power of the fish heating rod is related to the fish volume. The traditional fish rainbow heating rod generally has 1W heating power corresponding to 1 liter of water, and in 30-50L fish rainbow, the corresponding heating power is 50W; the fish rainbow volume is 60-100L, corresponding The heating power is 100W; the dimensions of the two heating rods are Φ27*265ηιηι, the volume of the fish tank is 150-200L, and the corresponding heating power is 200W; the size of the heating rod used is Φ 27*320mm, and the volume of the fish tank is 250- 300L, the corresponding heating power is 300W, the size of the heating rod used is Φ27*360ηιηι) The weight of the above heating rod is 240-328g, which has the problem of occupying the fish tank area, hindering the fish activity and affecting the viewing effect.

4. The above-mentioned fish tank heating rods are all indirect heating, which is characterized in that the independent heating elements cannot be directly placed in the water to contact each other. The principle of indirect heating means that the heating wire is radiated outward through the quartz sand, the glass interlayer and the metal tube layer, so that there is also a problem of low heating efficiency.

5, the above-mentioned fish tank heating rod, the working method is that after the power is turned on, the heating wire first conducts a part of the heat energy to the ceramic rod, and then slowly releases it through the glass tube compartment or the heat radiation with the metal tube compartment. Thermal energy, which has poor heat exchange performance and low heating efficiency. At the same time, due to the light weight of the hot water, the hot water molecules flow in the vertical upward direction to form a local or regional water temperature too high, which leads to insufficient water temperature of the fish tank to affect the normal growth environment of the fish.

6. The above-mentioned fish tank heating rod has a single function, which cannot purify water and decompose harmful substances in water. The so-called "can not purify water, decompose harmful substances in water" refers to the presence of harmful substances in fish tanks or culture ponds. For example, ammonia and nitrous acid require nitrifying bacteria to oxidize and decompose, while nitrifying bacteria must survive in water with extremely high oxygen content. , and reproduction does not follow the law of separation and free combination, the reproductive cycle is long, and the reproduction speed is very slow. And those that are heterogeneous (also known as "isoxic" or "anaerobic", is a generic term for water-purifying bacteria.) Compared with saprophytic bacteria within 20 hours, a heterotrophic bacterium can be split into 1 billion However, the nitrifying bacteria still stay in the original state, mainly because the fish excretion is decomposed too fast by the bacteria, and the nitrifying bacteria are too slow to process so much ammonia. Out of the crowd. Due to the lack of nitrifying bacteria, the ammonia content in the water will increase rapidly, causing the fish in the aquarium or the culture pond to be in danger of being hypoxic and lethal. In aquaculture ponds or fish tanks, aerobic nitrifying bacteria and isoxic water purification bacteria are purifying The water quality process has mutual inhibition, but at the same time it plays an important role in purifying water quality. In an ideal aquarium or aquaculture pond, a nitrogen compound circulatory system is formed due to the compatibility between bacteria. Nitrifying bacteria must survive in water with extremely high oxygen content, while water-purifying bacteria survive by organic pollution in water. From the ecological point of view of pool water, it is impossible to prevent the production of ammonia, but it can try to increase the amount of nitrifying bacteria to consume a large amount of ammonia in the aquarium or aquaculture pond. Therefore, it is necessary to purify the water, decompose the organic matter in the water, and increase the oxygen content in the water for nitrification. Bacteria provide a good habitat for breeding.

The advantages and effects of the utility model:

1. Due to the use of crystalline ceramic thick film (KMCH) heating element, it overcomes many inconveniences and deficiencies caused by heating wire heating commonly used in the prior art, fundamentally changing the heating principle, heating form of the existing aquarium heating device, Heating mode and heating structure.

The salient features of the crystal ceramic thick film electrothermal substrate are as follows:

(1) Due to the fully enclosed structure, the heating element is completely separated from the external environment, so that the new type of heater is not affected by the high humidity environment, and its safety performance is greatly improved. At the same time, due to the fully enclosed structure, the main part of the heater except the wire can be directly immersed in the liquid for heating.

(2) Since the solid powdery arc-extinguishing filler 27 is filled in the cavity of the pedestal, the arc generated by the abnormality of the heating element can be alleviated, and the operation of the heater can be made safer and more reliable.

(3) Excellent thermal characteristics: controllable temperature and heat shock resistance, immersed in water at 500 °C (25 °C), no breakage, no failure; high power density, up to 60W/cm2; Aquarium heating device, heating efficiency High, good heat exchange performance, not easy to scale. Since the basic material of (KMCH) is ceramic, which has the characteristics of fear of falling, fear of collision, and fragility, the utility model uses a metal-like hard shell to encapsulate it, thereby improving the impact resistance and anti-collision performance.

(4) Under the working condition, the utility model has no open flame, good insulation performance, high insulation strength, high resistance to 4000VAC, moisture proof, waterproof and corrosion resistance.

(5) No power attenuation, no inrush current, stable and efficient operation.

(6) The resistance temperature characteristics are good. In the application of the aquarium heating device, see Figure 8, which is the RT curve. The RT curve is flat, indicating that the power is stable after heating and there is no electromagnetic interference.

(7) High reliability: High dielectric strength and volume resistance. Good insulation strength, direct contact with metal, ceramic or water, anti-corrosion, anti-aging and long service life.

(8) Environmental protection and energy saving features: No noise, excellent energy saving, suitable for manufacturing aquarium heating devices and aquarium heaters, which can save 30% energy compared with traditional aquarium heating rods under the same conditions. In the heating process of the traditional aquarium, since the heating device adopts the indirect heating mode, the heat exchange efficiency is low, and the heated water slowly loses part of the heat energy through the air while being heated, and the heating time period is long, resulting in waste and loss of electric energy. phenomenon. Since the utility model adopts the direct heating mode, the heat exchange efficiency is high, so the heating time period is short, thereby improving the remarkable effect of energy saving by 30%.

(9) There are obvious biological effects, so that the negative ions in the water can adjust the pH of the water and enhance the metabolism of the cells. Reduce the hardness of water, increase the amount of oxygen dissolved in water, reduce residual chlorine, iron and heavy metals in water, which is beneficial to the growth of fish. Generally speaking, there are two main reasons for the generation of negative ions: One is to use high-voltage electricity to generate ionization to generate negative ions in the air, such as thunder and lightning in the sky. The air generates a large amount of negative oxygen ions after lightning, so we often feel lightning. The air after is very good. The other is the use of natural minerals, scientifically processed to become a material that can release negative ions. There are many energy stones on the earth, there are various ores, seaweed seabed stones and light shale containing protein. This material is processed into fine powder by high-tech technology, and it is compatible with polymer materials. Many negative ions can be studied. Functional products, the amount of negative ion release of these products can reach 1200-5000 per cubic centimeter, no less than the amount obtained by humans in the suburbs, the natural environment of the field. The utility model utilizes a material capable of releasing negative oxygen ions to solve the purified water Functionally, the water purification function is mainly solved by the far infrared rays released by the negative ion powder added in KMCH.

Scientific research has shown that negative ion powder can greatly help the human body to maintain energy and improve the living environment of human beings. Negative ion powder is characterized by natural, odorless, non-toxic and safe. It is also beneficial to the growth of the fish and the improvement of the environment.

The components in the anion powder have thermoelectricity and piezoelectricity, so that in the case of temperature and pressure changes (even small changes), the potential difference between the constituent crystals can be caused, and the static electricity is as high as 1 million electron volts, thereby making the air Ionization occurs, and the hit electrons attach to adjacent water and oxygen molecules and convert it into air negative ions, ie, negative oxygen ions.

(10) Using the unique characteristics of the crystal-ceramic thick-film electrothermal substrate (KMCH) and the addition of negative ion powder, it is compounded into a heating device having a far-infrared and water-purifying function. Negative ion powder has a strong far-infrared emission function. The composition in the ionic powder is a silicate material of aluminum, sodium, iron and lithium ring structure characterized by boron. The isomorphism is similar. Due to its pyroelectricity and piezoelectricity, the polar ions are Balanced position vibration causes dipole moment change to generate electromagnetic radiation in the far-infrared band. If it is added to the product (such as fiber) in a certain proportion, it passes its own free ions, impurity ions and ionic substances, impurities and The three-voice resonance produces radiation, which affects the polar vibration of the ion bond between the organic and inorganic molecules, forming a strong radiation broadband. According to the test, the negative ion powder has an emissivity of more than 90% for far-infrared.

It is a fish tank adding device made of a composite material with microcrystalline components, a negative oxygen ion component and an infrared component by an advanced process formulation, which promotes the oxygen content of the aquarium water. The activation of far-infrared rays in water is that far-infrared rays resonate with water molecules in water, interrupting the original macro-chains in the water, effectively reducing the molecular structure of ordinary water, and rearranging the polarity of water. Combined with a stable small molecule group (5-6) small molecules, the amount of dissolved oxygen in the water is greatly improved, providing a favorable ecological environment for the nitrifying bacteria.

(11) Domestic procurement of raw materials used, no pollution in the production process, short production cycle, low production cost, and no exhaust gas pollution in the applied products. Excellent performance. Meet ROHS requirements, green and environmentally friendly.

2. The utility model is made of microcrystalline component (KMCH) and negative ion powder material. Water-functioning aquarium heating device, the advantages of the invention are:

(1) Small size, up to 70*15*2.5 mm length * width * thickness. The size of the shell is 80*20*6 mm, and the maximum power can be 600W without changing the size. (The traditional glass tube heating rod power is 300W, the largest size is Φ27*360 ηιηι)

(2) Light weight Shell size 80*20*6 mm, weight less than 100g (conventional glass tube heating rod size is Φ27*360, weight is 328g)
