Problems solved by technology

These two types of insulation beds do not have a special heat storage layer. Although concrete has a certain heat storage performance, the heat storage coefficient is small and the total heat storage capacity of the insulation bed concrete is small. Short, poor constant temperature effect, electric heating device needs to be energized frequently, wasting electricity

Embodiment 1

[0015] Embodiment 1 The phase change material mixed in the concrete adopts microencapsulated phase change material, and the phase change material can adopt inorganic or organic phase change material. Since the suitable temperature for heating livestock and poultry is 20-40 degrees, it is suitable for inorganic The phase change material can choose inorganic hydrated salt, for example, sodium sulfate hydrated salt (Na 2 SO 4 10H 2 O), the dodecahydrate salt of disodium hydrogen phosphate (Na 2 HPO 4 12H 2 O) and the hydrated salt of calcium chloride (CaCl 2 ·6H 2 (2) etc., although inorganic hydrated salts are cheap in cost, supercooling and precipitation are ubiquitous, so preferably adopt organic phase-change materials, organic phase-change materials can adopt paraffins, higher fatty acids and alcohols etc., and paraffins can adopt commodity The phase change materials, such as the phase change energy storage material wax produced by Sinopec Nanyang Paraffin Fine Chemical...

Embodiment 2

[0016] Embodiment 2 In view of the high cost of the microcapsule phase change material, the phase change material is adsorbed in the porous material by means of adsorption, and the phase change material is fixed in the pores by using the porosity and capillary adsorption force of the material. Porous perlite or diatomaceous earth can be selected as the adsorption material. Add perlite or diatomite and phase change material paraffin into a vacuum container with a heating and stirring device. The heating temperature exceeds the melting temperature of the phase change paraffin. Make the paraffin fully enter the micropores of the adsorption material, the weight of the adsorption material to absorb the paraffin is 40%-65%, and the seepage ratio of the paraffin is less than 15% as the boundary. Due to the low thermal conductivity of the adsorption material and paraffin, a graphite heat-conducting material can be added to enhance the thermal conductivity of the paraffin, and the added...

Abstract

The invention provides a livestock heating electric heating plate. The livestock heating electric plate comprises an electric heating device, a reflecting layer, a heat insulating layer, a reinforcing mesh and concrete wrapped inside the reinforcing mesh, and is characterized in that a phase-change material is contained in the concrete. According to the livestock heating electric heating plate with the phase-change material added in the concrete, the heat storing capacity of the electric heating plate is increased by 8 to 10 times, the fluctuation of the temperature of the electric heating plate is reduced, the frequent action of the electric heating device is decreased, and the heat preservation time can be prolonged during power failure.

Description

technical field [0001] The invention relates to an electric heating plate for heating livestock and poultry. Background technique [0002] In the northern region, the outdoor temperature is generally minus 10-20 degrees Celsius in winter. Livestock and poultry cubs in pens need to be provided with a suitable temperature to grow healthily. Using the overall heating of the building to achieve a suitable room temperature for the cubs consumes a lot of fuel. To solve the problem of keeping the cubs warm in winter, pig farms generally use thermal insulation beds for the cubs in winter, and the thermal insulation beds can be heated by fuel or electric. Because livestock and poultry breeding manure is everywhere, the electric heating plate must be waterproof and easy to clean, so the pig house insulation bed is generally assembled or packaged with glass fiber reinforced plastic or plastic waterproof outer cover, electric heating wire, protective layer, reflective layer, and thermal...
