Abstract
Description
Technical Field
[0001] The utility model relates to a heat shrinker, in particular to a light environmental protection soft curtain heat shrinker. Background Art
[0002] There is no light and small equipment suitable for compressing the volume of waste polystyrene EPS foam in urban community waste collection stations. Existing plastic lump machines and granulating machines are large in volume, noisy, and have environmental protection problems of dust and organic waste gas, so they are prohibited from being used in urban residential areas.
[0003] The waste collection stations in each residential community only simply classify and stack. Waste polystyrene EPS foam has an extremely low density, usually 0.02 g / cubic centimeter; the products have high strength and are difficult to be manually compressed and stacked like cardboard boxes and plastic films. The space utilization is extremely low, the transportation frequency is high, the storage and transportation investment is too large, and the economic benefits of the acquisition points are poor.
[0004] The operation process is to load the waste polystyrene foam into a container, send it into the heat shrinker, and after more than 20 minutes of heat shrinkage treatment, then treat the waste gas through the waste gas treatment system for 3 - 5 minutes to meet the discharge standards. The heat shrinker can reduce the foam volume by more than 95% and increase the density by about 20 times.
[0005] In view of the extremely low density of EPS foam, in order to improve production efficiency, it is necessary to increase the volume of the furnace chamber, while the user's demand is that the equipment volume is as small as possible. To solve this contradiction, the heating operation platform of the light environmental protection soft curtain heat shrinker is designed to be foldable. When not in use, the equipment can be folded and shrunk, greatly reducing the storage space.
[0006] For waste recycling, cost is the key. The specially designed soft curtain plays a role in sealing and heat preservation. The operating power of the equipment is extremely low, only equivalent to that of ordinary household kitchen appliances. The heat shrinkage treatment of waste EPS foam is extremely energy-saving.
[0007] The waste collection station can heat shrink the polystyrene foam received on the same day during idle time. The heat-shrunk foam greatly saves storage and transportation costs.
[0008] Publication No. CN 219468236 U discloses a light environmental protection foam heat shrinker. Since the chamber wall and chamber door of the heat shrinkage chamber are both hard plate-type structures, when placing the foam to be compressed into the heat shrinkage chamber, the foam will be restricted by the shape of the chamber. Since the recycled foams have various shapes, even if they are initially cut and trimmed into large pieces and then placed into the chamber, the gaps between each foam block are large, severely limiting the actual working load volume of the heat shrinker and resulting in a low actual working efficiency. Summary of the Invention
[0009] To solve the above technical problems, the utility model aims to provide a light environmental protection soft curtain heat shrinker, which can increase the actual working load volume of the heat shrinker, improve the single working load capacity without increasing the overall volume of the heat shrinker, and thus improve the working efficiency.
[0010] A light environmental protection soft curtain heat shrinker in this solution includes a chassis and a heat shrinkage chamber. The heat shrinkage chamber includes a back plate, a bottom plate and a top plate. The back plate, the bottom plate and the top plate form the chamber body of the heat shrinkage chamber, and the chamber body is enclosed by a heat preservation soft curtain.
[0011] The chamber body is composed of a back plate, a bottom plate and a top plate, and the other three sides are blocked and enclosed by a heat preservation soft curtain. Due to the deformable characteristic of the heat preservation soft curtain itself, even if the materials (here referring to recycled foam) exceed the cubic structure space of the chamber body, the closing work can still be carried out normally. The materials exceeding the volume will gradually collapse downward during the heating process, and the heat preservation soft curtain will slowly return to the vertical state. Moreover, using the soft curtain structure instead of the hard metal plate structure not only reduces the structural cost but also reduces the weight of the equipment itself, making it more convenient for transportation.
[0012] Further, the heat preservation soft curtain includes a first curtain body and a second curtain body. One ends of the first curtain body and the second curtain body are respectively fixed on both sides of the chamber body, and the first curtain body and the second curtain body are arranged to open towards the middle of the chamber body.
[0013] Further, the first curtain body and the second curtain body have the same structure and are symmetrically arranged on both sides of the chamber body.
[0014] Further, one end of the first curtain body is fixed to one end of the back plate, and a first support rod is fixedly arranged at the end of its free end. One end of the second curtain body is fixed to the other end of the back plate, and a second support rod is fixedly arranged at the end of its free end. The first support rod and the second support rod can be fitted and fixed. One end of the curtain body is vertically fixed, and the other end is the free end, which can be closed by fitting a pair of support rods or opened.
[0015] Further, both ends of the first support rod and the second support rod exceed the bottom plate and the top plate. A fixing component is arranged on both the top plate and the bottom plate. The fixing component is slidably arranged on the top plate and the bottom plate, and a clamping groove for accommodating the first support rod and the second support rod after fitting is arranged on the fixing component.
[0016] Further, the fixing component includes two symmetrically arranged L-shaped clamping plates. The L-shaped clamping plate includes a flat plate and a vertical plate. The flat plate is slidably arranged on the bottom plate and the top plate. The first support rod and the second support rod after fitting are accommodated between the two vertical plates, and a connecting plate is arranged between the two vertical plates.
[0017] Further, the heat-insulating soft curtain sequentially includes a high-temperature resistant and fireproof inner layer, a heat-insulating intermediate layer, and a sun-proof and rain-proof outer layer from the inside to the outside. The heat-insulating soft curtain can effectively isolate the heat generated during the internal operation of the heat shrinker, make full use of the heat energy, ensure the comfort of the working environment of the people outside the heat shrinker, and protect the internal components of the heat shrinkage chamber.
[0018] Further, a plug rod is respectively provided at the top ends of the rod bodies close to the first support rod and the second support rod, fixing plates are respectively provided at corresponding positions at both ends of the top plate, and insertion holes adapted to the plug rods are formed on the fixing plates. The plug rod and the insertion hole can be used to hang the curtain body, keep the bin body in an open state, and facilitate the addition and removal of materials.
[0019] Further, the first curtain body and the second curtain body are detachably connected to the edge of the top plate through magic tapes. The magic tape connection method can be arbitrarily detached and fixedly connected, is convenient to use, has stable connection, and has low cost.
[0020] Further, the bottom plate is rotatably connected to the back plate; the top plate is rotatably connected to the back plate. The bottom plate and the top plate can be folded and retracted, which can reduce the overall volume of the equipment and is convenient for transportation and storage.
[0021] The advantages of the present utility model are as follows: The heat shrinkage chamber body of the heat shrinker in the prior art for placing materials is a rigid metal plate structure. After its bin door is closed, it is a closed cuboid bin body structure. Foamed materials cannot overflow the bin body for placement. Since there are large gaps between the stacked foam blocks of the materials, the actually contained materials are less, resulting in a low actual heat shrinkage amount of the heat shrinker each time, low work efficiency, and the need to increase the number of operations. In this solution, the two side plates and the bin door of the original bin body are replaced with a soft curtain structure. Due to the soft and deformable characteristics of the soft curtain itself, the placed materials can overflow the cuboid area slightly. When the heat shrinker works, the soft curtain will gradually return to its natural vertical position after the foam shrinks.
[0022] In this way, the amount of heat-shrinkable foam of the heat shrinker can be increased each time, the number of manual filling operations can be reduced, and the soft curtain replaces the metal plate structure, reducing the material cost, reducing the overall self-weight of the heat shrinker, being more convenient for storage, movement and transportation, and having stronger practicability.

The bin body is composed of a back panel 2-1, a bottom plate 2-2 and a top plate 2-3, and the other three sides are blocked and enclosed by the heat-insulating soft curtain 4.
[0030] Due to the deformable characteristic of the heat-insulating soft curtain 4 itself, even if the recycled foam materials exceed the cubic structure space of the bin body, the heating work can be carried out normally after being enclosed. The materials exceeding the volume will gradually collapse downward during the heating process, and the heat-insulating soft curtain 4 will slowly return to the vertical state.
