Abstract

The invention discloses an environment-friendly energy-saving cold storage and aims to solve the problems of great cold loss of the wall of a cold storage and energy waste caused by the excessively thick wall. Good functions of sound insulation and thermal insulation can be realized by vacuum., so the best choice is to adopt a vacuum wall as a thermal insulation wall of the cold storage. In the invention, sawdust, straws, rice hulls, crop stalks, even garbage and the like are crushed into particles smaller than 0.1 mm; then the waste water-resistant materials such as waste plastic bags, plastic cloth, plastic plates, woven bags and the like are crushed in the same way; the particles are mixed at a proportion of 10%; a proper amount of fire retardant, preservative, age resister and dye is added into the mixture; a cheap high-density sheet is manufactured from the mixture; and a vacuum plate is manufactured from a new building material. A cold storage is built simply by finishing the foundation of the cold storage and the building frame; and an outer wall, an inner isolation wall, an upper cover and the like of the cold storage are all formed by vacuum plates. The vacuum plate has simple process, low cost, obvious energy saving effect and enormous social and economic significance.

Description

The environmental protection and energy saving freezer

(1) technical field

The present invention relates to a kind of Cold Storage Building, particularly relate to a kind of energy-conservation freezer.

(2) background technology

Along with the development of society, people's living standard improves constantly, and bread is the staff of life, how to guarantee safety, health, environmental protection, the nutrition of food, is the big problem of the most important thing that concerns that people are healthy.Particularly need low temperature, refrigeration, freezing, the anxious food that freezes, a feast for the eyes, of all shapes and colors, build efficient, environmental protection, energy-conservation constant heat storage, cold store, freezer, suddenly freeze the storehouse and have great significance!

At present, the construction to freezer has both at home and abroad had significant improvement, as; Body of wall changes the benzene plate into by rice husk, sawdust sandwich wall and pastes, and polyurethane foaming or spraying etc. had been arranged again in recent years, and refrigerant is freezed to wind by ammonia refrigeration, freon refrigeration; Basically can satisfy freezing demand; But present freezer is wasted mass energy in refrigeration; Water, electricity, oil, ammonia etc., basic reason is;

One, wall race cold is big, wastes energy

Freezer mostly adopts brick, the middle building structure that adds insulation layer of concrete casting at present.Brick, concrete coefficient of thermal conductivity height, and middle insulation layer adopts any material all to have leakage slowly, so all want every day wasteful water gaging, electricity to replenish low-temperature receiver.

Two, too thick big quantity space, the reduction utilization rate of taking of wall

By Cold Storage Building brick, concrete casting therebetween insulation layer, its wall is too thick, and mostly more than 1 meter, its utilization rate of same building reduces about 20%.Therefore, build a kind of efficient, environmental protection, power saving refrigerator is trend of the times.

Three, summary of the invention

The objective of the invention is to develop and solve the freezer wall and run the big and too thick problem that wastes energy of wall of cold.As everyone knows, vacuum has the function well of sound insulation, thermal insulation.Is best choice with the vacuum wall as the insulated wall of freezer.

The technical scheme of taking is;

Select for use a kind of novel constructional materials to be made into the vacuum plate.The present invention is as long as accomplish the ground and the building frame of freezer, and the exterior wall of its freezer, internal partition wall, loam cake etc. all are made up of the vacuum plate.Its vacuum plate is by batch production production, and assembly type is installed.

Specific embodiment;

One, the manufacturing of evacuated panel;

Method is that sawdust, straw, rice husk, stalk even rubbish etc. are ground into the particle less than 0.1 millimeter; Then with waste plastic bag, Polypropylence Sheet; Water-resistant material such as plastic plate, woven bag is pulverized the back equally with 10% mixed; Add amount of retardant, anticorrisive agent, age resister, dyestuff again, be made into the high density thin plate, as long as airtight.Skeleton can become rectangular framework with steel or aluminium or material such as timber or the compound material of stalk, seals after wrapping skeleton with the high density thin plate, deflates with vacuum machine again, promptly can be made into the evacuated panel material.As need not deflate, then can be made into sealed hollow sheet material, have good heat insulation, sound insulation, waterproof effect equally.The thickness of vacuum sheet material can be according to the needs of heat insulation, sound insulation, waterproof and the policy setting of saving.The skeleton of vacuum wall can use number of various materials according to the needs of load-bearing and intensity, and skeleton can use steel, aluminium, timber or composite material to make.The thickness of vacuum wall equals two thickness of skeleton extraordinarily of lamella thickness.The thickness of vacuum wall can be set according to the needs of heat insulation, sound insulation, waterproof.The distortion of vacuum wall can be set the distortion of skeleton.Like arc vacuum wall, triangle vacuum wall or the like.The color of vacuum wall is set arbitrarily.Its meaning is to have exempted the decorations of exterior wall in the construction project, has shortened the construction period, has saved lot of manpower and material resources, has exempted noise pollution and formaldehyde and has polluted, and is easy to beautifying constructure.Desired seal technology in the manufacture process of vacuum wall, thin plate are technological, vacuum technique etc. all is the ripe known technologies in the industry, and technology is simple, cost is low, and energy-saving effect is remarkable, and social effect, economic implications are huge.

Two, the construction of vacuum freezer;

The present invention is as long as accomplish the ground and the building frame of freezer, and the exterior wall of its freezer, internal partition wall, loam cake etc. all are made up of the vacuum plate.Its vacuum plate is by batch production production, and assembly type is installed.If build constant heat storage, cold store individual layer evacuated panel get final product, if build freezer, urgency is frozen the storehouse and can be assembled into two-layer or three layers.

The good effect that the present invention obtains;

1 is in light weight, is the one thousandth of existing freezer;

2 materials are extensive, but all twice laids and do not influence architectural effect of various nontoxic material even discarded object;

3 simple installations, easy care, particularly the cool house internal structure can be assembled arbitrarily as required, installs, reequiped;

4 life-spans are long, and the general life-span of existing building is 20-40, and the Cold Storage Building of this project is a permanent construction, can change arbitrarily when evacuated panel is aging, not limited by the time limit, and can change outer shape, internal construction arbitrarily;

5 reduce cost of transportation and construction cost 80% construction material cost reduction by 50%

6 is splendid because of vacuum sound insulation, thermal insulation effect, so that the freezer wall does not need is too thick, the freezer of same scale can increase by 20% usable floor area, promptly increases by 20% economic benefit;

7 because the heat insulation effects of vacuum are higher than existing freezer, but conserve water, electric cost 20%, and can prolong the commodity shelf-life;

The present invention invests then then and takes effect, and once investment, income throughout one's life.Therefore, the freezer of the present invention's building will be eliminated existing freezer.
