Description

Technical field:

[0001] The utility model relates to the technical field of quartz crucibles, in particular to a melting room for producing quartz crucibles. Background technology:

[0002] In the quartz crucible production industry, arc discharge during the crucible melting process will generate high-frequency noise and high temperature. Due to the mixture of high-frequency noise and high temperature, the nearby walls and exhaust ducts will vibrate greatly, resulting in wall cracks and duct cracks.

[0003] The current solution is to install asbestos boards on the inner wall of the melting room for sound insulation, but this does not solve the problem of high temperature. It still causes great harm to equipment and personnel during the production process, and also causes waste of energy. Utility model content:

[0004] The purpose of the utility model is to provide a melting room for producing quartz crucibles to solve the problems raised in the above-mentioned background technology.

[0005] The utility model is implemented by the following technical solutions:

[0006] A melting room for producing quartz crucibles comprises a room body, sound-absorbing shutters, asbestos boards, micro-perforated plates, a layer of micro-perforated plates, a heat exchange coil and a second layer of micro-perforated plates; sound-absorbing shutters are installed on the walls on both sides of the bottom of the room body, asbestos boards are installed on the surrounding walls and the top wall of the middle and upper part of the room body, an exhaust port is opened in the middle of the top wall of the room body, four obliquely arranged micro-perforated plates are installed around the top wall of the room body and below the exhaust port, and a layer of micro-perforated plates, a heat exchange coil and a second layer of micro-perforated plates are fixedly arranged in sequence in the room body from the exhaust port downward.

[0007] Preferably, the micro-perforated plate is an isosceles trapezoidal structure, and four of the micro-perforated plates are connected to form a quadrangular pyramid structure, the lower base of each micro-perforated plate is fixed on the surrounding walls corresponding to it, and the upper base of each micro-perforated plate is fixed on the top wall.

[0008] Preferably, the room body is also equipped with an exhaust hood above the exhaust port.

[0009] Preferably, the water inlet and the water outlet of the heat exchange coil are respectively connected to the cooling water pipes in the factory.

[0010] The advantages of the utility model are as follows: the noise is further absorbed by four micro-perforated plates, one layer of micro-perforated plates and two layers of micro-perforated plates, thereby reducing the noise in the room; at the same time, the high temperature generated is exchanged with the cooling water in the heat exchange coil, so that the temperature in the room is effectively cooled down, and at the same time, part of the cooling water is heated by the high temperature after the heat exchange and recycled in the factory for recycling, thereby effectively reducing the loss and waste of heat.

[0017] A melting room for producing quartz crucibles, comprising: a room body 1, a sound-absorbing louver 2, an asbestos board 3, a micro-perforated board 4, a first layer of micro-perforated board 5, a heat exchange coil 6 and a second layer of micro-perforated board 7; the sound-absorbing louvers 2 are installed on the walls on both sides of the bottom of the room body 1 to reduce some noise in the room body 2; the asbestos board 3 is installed on the surrounding walls and the top wall of the middle and upper part of the room body 1, an exhaust port 1.1 is opened in the middle of the top wall of the room body 1, and an exhaust hood 8 is also installed on the room body 1 above the exhaust port 1.1. Four inclined micro-perforated plates 4 are installed around the top wall of the room 1 and below the exhaust port 1.1. The micro-perforated plates 4 are isosceles trapezoidal structures. The four micro-perforated plates 4 are connected to form a four-sided pyramid structure. The lower bottom edge of each micro-perforated plate 4 is fixed on the surrounding walls corresponding to it, and the upper bottom edge of each micro-perforated plate 4 is fixed on the top wall. A layer of micro-perforated plates 5, a heat exchange coil 6 and a second layer of micro-perforated plates 7 are fixed in sequence from the exhaust port 1.1 downward in the room 1. The water inlet and outlet of the heat exchange coil 6 are respectively connected to the cooling water pipes in the factory area. Most of the noise and heat are concentrated and transferred to the middle of the four micro-perforated plates 4 through the structure, thereby reducing the vibration of the nearby walls caused by high-frequency noise and high temperature, and avoiding the cracking of walls and pipes.

[0018] The working principle is as follows: the noise is further absorbed by four micro-perforated plates 4, a layer of micro-perforated plates 5 and a second layer of micro-perforated plates 7, thereby reducing the noise in the room 1; at the same time, the high temperature generated is heat-exchanged by the cooling water in the heat exchange coil 6, so that the temperature in the room 1 is effectively cooled down. At the same time, part of the cooling water is heated by the high temperature after the heat exchange and recycled in the factory, thereby effectively reducing the loss and waste of heat.
