Abstract
Description
Technical Field
[0001] The utility model relates to the field of epoxy coil production, in particular to an oven for epoxy coil production. Background Art
[0002] Epoxy coil is a new type of floor material. It is a polymer composite material with an elastomer toughened epoxy resin and polyurethane composite resin system as the matrix, glass fiber toughening and reinforcement, and prepared through a special curing process. The epoxy coil is cross-linked and cured under constant high temperature and high pressure conditions, so that it has a high cross-linking density and cross-linking regularity, thereby ensuring that the material has excellent physical and chemical properties. The epoxy coil is produced using a solvent-free system formula. It does not release and does not contain any toxic gases during installation and use. It is safe to use and complies with environmental protection concepts. At present, in the process of processing epoxy coil, the coil needs to be dried. The coil dried in an oven can accelerate curing, improve adhesion, remove bubbles and moisture in the coil, and improve surface quality. However, in the existing technology, the hot air in the drying process blows the coil unevenly, resulting in low product quality. Therefore, there is an urgent need for an oven for epoxy coil production to ensure that the coil can be evenly blown by hot air and improve the quality of the coil. Utility Model Content
[0003] The purpose of the utility model is to provide an upper oven for epoxy coil production, which can ensure that hot air can be blown evenly onto the coil, so that the coil is heated evenly during the drying process and the quality of the coil is improved.
[0004] An upper oven for epoxy coil production is characterized in that it includes a box body, a fan, and a three-way pipe. Waste heat pipes are respectively provided on both sides of the box body, one end of each waste heat pipe is an air inlet and the other end is an air outlet, each of the air inlets is connected to the outside air, and each of the air outlets is connected to the fan. A steam heat exchanger is provided above the box body, and an air inlet and an air outlet are provided on the steam heat exchanger. The air inlet of the steam heat exchanger is connected to the fan, and two purge ports are provided above the box body. The two purge ports are connected to the steam heat exchanger outlet through a three-way pipe, and at least one wind shield mechanism is provided below the two purge ports.
[0005] Preferably, the wind shielding mechanism is an inverted trapezoidal structure with an upper opening.
[0006] Preferably, a plurality of small holes are evenly arranged on the bottom of the wind shielding mechanism, and the small holes are circular in shape.
[0007] Preferably, the diameter of the small hole is 3mm-6mm.
[0008] Preferably, the box body is provided with a waste gas collecting port, and the waste gas collecting port is connected to a waste gas collecting device.
[0009] Preferably, each of the waste heat pipes runs through the interior of the box.
[0010] Preferably, a temperature sensor is provided at the outlet of the steam heat exchanger.
[0011] Preferably, the steam heat exchanger is provided with a steam inlet and a steam outlet, and a regulating valve is provided at the steam inlet.
[0012] Preferably, a mounting frame is provided on the box body, and the steam heat exchanger is welded to the mounting frame.
[0013] Preferably, at least one fixing block is provided on the mounting frame at the bottom of the steam heat exchanger.
[0014] Beneficial effects
[0015] 1. The utility model connects the air outlet of the steam heat exchanger with two purge ports through a three-way pipe, which diverts the heat of the steam. After the diversion, the heat of the steam is more evenly distributed. The heat of the steam heats the air into hot air. The diverted steam is blown downward from the purge port. When the steam passes through the wind shield mechanism, most of the steam remains above, blowing the hot air onto the surface of the coil, avoiding the steam directly blowing the coil, which may cause quality problems in the product.
[0016] 2. The utility model is provided with a plurality of small holes at the bottom of the wind shield mechanism. The small holes are circular. Hot air is blown toward the small holes under the action of the fan. The hot air acts evenly on the surface of the coil through the small holes, while most of the steam with a higher moisture content is blocked above, so that the steam will not directly contact the coil. The hot air is evenly blown downward under the action of the small holes, effectively improving the product quality of the coil. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0024] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0025] like Figures 1 to 3As shown, an upper oven for epoxy coil production is characterized in that it includes a box body 1, a fan 4, and a three-way pipe 6. Waste heat pipes 10 are respectively provided on both sides of the box body, one end of each waste heat pipe is an air inlet 2 and the other end is an air outlet 3, each air inlet is connected to the outside air, and each air outlet is connected to the fan. A steam heat exchanger 5 is provided above the box body, and an air inlet 501 and an air outlet 502 are provided on the steam heat exchanger. The air inlet of the steam heat exchanger is connected to the fan, and two purge ports 7 are provided above the box body, and the two purge ports are connected to the air outlet of the steam heat exchanger. It is connected through a three-way pipe, the air inlet end of the three-way pipe is connected to the air outlet of the steam heat exchanger, and the two air outlet ends of the three-way pipe are connected to the two purge ports respectively. The steam is diverted through the three-way pipe to reduce the wind pressure. The diversion of the three-way pipe is uniform and stable, which can ensure that the steam and the hot air heated by the steam are blown out evenly from the two purge ports. At least one wind shield mechanism 11 is provided under the two purge ports. The wind shield mechanism can block most of the water vapor blown out of the purge port, effectively preventing the water vapor from directly acting on the coil, causing uneven heating of the coil surface and quality problems.
[0026] The windshield is an inverted trapezoidal structure with an opening at the top. The upper opening of the inverted trapezoidal structure is large and can gather steam and hot air, while the lower opening is small. A number of small holes 12 are evenly arranged at the bottom of the windshield. The small holes are circular holes. Steam and hot air gather at the bottom. Under the action of the fan, the hot air acts evenly on the coil through the small holes, and the steam continues to move forward along the blowing direction of the fan. The diameter of the small holes is 3mm-6mm, and the small holes are evenly distributed on the entire bottom of the windshield to ensure uniform blowing. The hot air flows to the coil below through the fan. The windshield mechanism blocks most of the steam and transports the hot air to the top of the coil, thereby drying the coil. Direct contact of the steam with the coil may cause uneven heating of the coil, affecting the quality of the coil. The small holes on the windshield mechanism cooperate with the fan to accelerate the air flow, thereby improving the drying efficiency. Multiple windshield mechanisms are horizontally arranged below the box from the purge port to the exhaust gas collection port. There are seven windshield mechanisms in this embodiment, and a card strip 13 is provided on the windshield mechanism. A card slot matching the card strip is provided on the box. The windshield mechanism can be slidably installed in the card slot for easy regular maintenance.
[0027] The box body is provided with an exhaust gas collection port 9, which is connected to an exhaust gas collection device. The exhaust gas collection device is provided with an exhaust gas collection fan. The exhaust gas collection fan can suck the exhaust gas in the oven and treat it before discharging it, effectively preventing the exhaust gas released by the coil after high-temperature baking from polluting the workshop environment. The setting of the exhaust gas collection port effectively protects the environment of the workshop and ensures the health of the workers in the workshop. Each waste heat pipe runs through the interior of the box body. The waste heat pipes are symmetrically arranged on both sides of the box body. The fan needs to suck the air from the outside to push the steam in the heat exchanger forward. The waste heat pipe can effectively absorb the temperature in the box body to heat the air in the waste heat pipe, effectively utilizing the waste heat, so that the steam heat exchanger can heat the air to a temperature suitable for drying more quickly, maximize energy utilization, improve production efficiency, and save production costs.
[0028] A temperature sensor 8 is provided at the outlet of the steam heat exchanger. The temperature sensor can monitor the temperature of the hot air entering the purge port in real time. When the coil is baked, too high or too low a temperature will affect the quality of the coil. The temperature sensor can monitor the baking temperature in real time. When the temperature fluctuates, it can be adjusted in time to ensure the stability of the baking temperature, thereby ensuring the quality of the coil. The temperature sensor is electrically connected to a temperature display screen (not shown in the figure). The staff can see the temperature inside the oven according to the temperature display screen.
[0029] The steam heat exchanger is provided with a steam inlet 503 and a steam outlet 504. A regulating valve (not shown in the figure) is provided at the steam inlet. The regulating valve can adjust the steam intake amount. By adjusting the steam intake amount, the temperature in the steam heat exchanger is adjusted. The steam inlet on the steam heat exchanger is used to connect to a steam intake pipe (not shown in the figure). A steam outlet is provided below the steam inlet. The steam outlet is connected to a steam outlet pipe (not shown in the figure). The regulating valve is provided on the steam intake pipe.
[0030] The box body is provided with a mounting bracket 14, and the steam heat exchanger is welded to the mounting bracket. The mounting bracket is welded to two mounting rods on the box body. The surface hardness of the box body is relatively low, and directly mounting the steam heat exchanger on the box body may damage the box body. The mounting bracket composed of two parallel mounting rods can effectively distribute the weight of the steam heat exchanger evenly on the box body, avoiding damage to the box body caused by the steam heat exchanger being too heavy. Four fixing blocks 15 are welded to the bottom of the steam radiator. The fixing blocks can effectively reduce the vibration of the heat exchanger during operation. One end of each fixing block is welded to the mounting bracket and the other end is welded to the steam heat exchanger, which increases the stability of the entire device during operation. The fixing blocks are welded to the four corners of the bottom of the steam radiator. When the steam heat exchanger is working, the fixing blocks can support the steam heat exchanger to ensure the smooth operation of the steam heat exchanger. At the same time, the four fixing blocks also improve the stability of the entire oven, providing safety protection for the oven.
[0031] How it works
[0032] Under the action of the fan, the outside air enters the waste heat pipe from the air inlet, and the oven is in continuous operation. The air passing through the waste heat pipe will be heated by the waste heat in the oven, and the heated air enters the steam heat exchanger. Under the action of the fan, the air pushes the steam in the steam heat exchanger into the three-way pipe. In the three-way pipe, the steam is diverted and evenly diverted to the two purge ports. The steam is evenly blown downward from the two purge ports. After the steam moves to the windshield mechanism, most of the steam will be blocked by the windshield mechanism, and the air heated by the steam will pass through the small holes of the windshield mechanism under the action of the fan and act on the coil, thereby completing the uniform purge of the coil, ensuring that the coil is evenly heated, and thus improving the quality of the coil.
[0033] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
