Description

Technical Field

[0001] This utility model relates to the field of plastic manufacturing technology, specifically a mixing device for the production of glass fiber reinforced plastics. Background Technology

[0002] Glass fiber reinforced plastic, also known as fiberglass, is a functional new material made from synthetic resin and glass fiber through a composite process. It is significantly lighter than traditional metal products, yet possesses excellent strength and rigidity. It resists corrosion from acids, alkalis, salts, and other chemicals, maintaining stability and integrity under long-term cyclic loading. It is also easy to cut, drill, and bend. The production of glass fiber reinforced plastic requires raw material mixing, and the mixing effect is greatly affected by temperature. Large initial temperature differences between newly added raw materials and water can easily lead to poor mixing quality. Existing mixing devices typically use heating tanks, which easily cause temperature differences during material addition. Therefore, a new mixing device for glass fiber reinforced plastic production is needed.

[0003] According to application number CN202323068325.7, a raw material mixing device for the production of glass fiber reinforced flame retardant plastics is provided. The raw material mixing device for the production of glass fiber reinforced flame retardant plastics includes: a tank body, with multiple support legs fixedly installed at the bottom of the tank body, and a heating coil provided on the inner wall of the tank body; a top plate, which is located on the top of the tank body; a through pipe, which is rotatably installed on the top plate, and multiple stirring tubes for mixing glass fiber reinforced flame retardant plastic raw materials are fixedly installed on the through pipe, and the multiple stirring tubes are all connected to the interior of the through pipe; and a sealing cap, which is threadedly installed at the bottom end of the through pipe.

[0004] The aforementioned document describes a method of rapidly cooling the tank with circulating water for easy cleaning, but its applicability is limited and it cannot solve the problem of poor mixing quality caused by excessive temperature difference between newly added materials and already mixed materials during the feeding process. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a mixing device for the production of glass fiber reinforced plastics, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mixing device for producing glass fiber reinforced plastics includes a mixing tank, a tank cover at the top of the mixing tank, a water bath tank hanging on the outer wall of the mixing tank, a stirring component inside the mixing tank, a driving component at the center of the top of the tank cover, a preheating component at one end of the top of the tank cover, and spraying components on both sides of the top of the tank cover.

[0008] Preferably, the stirring component includes a bearing seat located at the center of the bottom of the mixing tank, a bearing tube located in the middle of the tank cover, and auger tubes at both ends of the central shaft respectively fitted inside the bearing seat and the bearing tube.

[0009] Preferably, the driving component includes a drive motor disposed on the top of the can lid, a right-angle reducer whose input end is connected to the actuation end of the drive motor, and a coupling connecting the right-angle reducer to the central shaft of the auger tube.

[0010] Preferably, the preheating component includes a feed pipe passing through one end of the tank cover, a first electronic valve located at the input end of the feed pipe, a preheating tank located at the top of the first electronic valve, multiple vertical heating pipes located at the bottom of the preheating tank, and an insulation cover located at the top of the preheating tank.

[0011] Preferably, the water bath includes a control panel on the side, an inlet pipe above one end of the water bath, an outlet pipe below the other end of the water bath, a first temperature sensor at the bottom of the mixing tank, and a second temperature sensor at the bottom of the insulation cover.

[0012] Preferably, the spraying component includes a pump located at the output end of the water outlet pipe, flanges located on both sides of the top of the tank cover, a spray head located at the bottom of the tank cover and connected to the flanges, and a tee pipe connecting the output end of the pump and the input end of the flanges.

[0013] Preferably, the mixing tank includes an annular heating tube wound inside the side wall, a discharge pipe located at one end of the bottom of the mixing tank, and a second electronic valve located at the output end of the discharge pipe.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this embodiment, by preheating the raw materials to be added in a preheating tank and preheating the liquid to be added in a water bath, the various materials are already at the set temperature when they enter the mixing tank. This ensures that there is no temperature difference between the new materials and the raw materials being mixed in the mixing tank, thus ensuring the mixing quality and effectively preventing the formation of lumps, stratification, and bubbles during the mixing process.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a mixing device for producing glass fiber reinforced plastics includes a mixing tank 10, a tank cover 11 located on the top of the mixing tank 10, a water bath 12 hanging on the outer wall of the mixing tank 10, a stirring component 13 located inside the mixing tank 10, a driving component 14 located at the center of the top of the tank cover 11, a preheating component 15 located at one end of the top of the tank cover 11, and spraying components 16 located on both sides of the top of the tank cover 11. The stirring component 13 includes a bearing seat 131 located at the center of the bottom inside the mixing tank 10, a bearing tube 132 located in the middle of the tank cover 11, and auger tubes 133 with their two ends sleeved inside the bearing seat 131 and the bearing tube 132, respectively. The driving component 14 includes a drive motor 141 located on the top of the tank cover 11, a right-angle reducer 142 whose input end is connected to the actuation end of the drive motor 141, and a coupling 143 connecting the right-angle reducer 142 and the central shaft of the auger tube 133.

[0026] It should be noted that the central shaft of the auger tube 133 passes through the inside of the bearing tube 132 and is connected to the coupling 143. The coupling 143 can be removed when maintenance is required to separate the auger tube 133 from the right-angle reducer 142, making it easier to remove the can lid 11. The can lid 11 has a handle on the top. Because the auger tube 133 is large and heavy, and is used to stir substances with high viscosity, the right-angle reducer 142 is used in this embodiment to increase the torque.

[0027] Furthermore, when mixing is required after the materials are added, the drive motor 141 at the top of the can lid 11 starts, and outputs a large torque through the right angle reducer 142, which drives the auger tube 133 to rotate through the coupling 143.

[0028] Furthermore, the auger tube 133 rotates around the bearing seat 131 and the bearing tube 132 as an axis, stirring the substances in the mixing tank 10 to carry out the mixing process;

[0029] Furthermore, when maintenance is required, the coupling 143 can be removed, and the can lid 11 can be opened using the handle on top of the can lid 11.

[0030] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 4 and 5, the preheating component 15 includes a feed pipe 151 passing through one end of the tank cover 11, a first electronic valve 152 located at the input end of the feed pipe 151, a preheating tank 153 located at the top of the first electronic valve 152, multiple vertical heating pipes 154 located at the bottom of the preheating tank 153, and an insulation cover 155 located at the top of the preheating tank 153; the water bath 12 includes a control panel 121 located on the side, a water inlet pipe 122 located above one end of the water bath 12, and a water inlet pipe 154 located at the top of the tank. The water outlet pipe 123 is located at the other end of the bath tank 12. The first temperature sensor 124 is located at the bottom of the mixing tank 10. The second temperature sensor 125 is located at the bottom of the heat preservation cover 155. The spray component 16 includes a pump 161 located at the output end of the water outlet pipe 123, flanges 162 located on both sides of the top of the tank cover 11, a spray head 163 located at the bottom of the tank cover 11 and connected to the flanges 162, and a tee pipe 164 connecting the output end of the pump 161 and the input end of the flanges 162.

[0031] It should be noted that the water bath 12 itself is a device that can control the water output at a constant temperature. The control panel 121 on the side can display the temperature of each sensor and the water outlet of the water bath 12, and has the function of adjusting the temperature of each heating element. The first temperature sensor 124 is responsible for monitoring the temperature of the mixture inside the mixing tank 10, and the second temperature sensor 125 is responsible for monitoring the temperature of the raw materials inside the preheating tank 153.

[0032] Furthermore, when it is necessary to add raw materials, the raw materials need to be added into the preheating tank 153 in advance, and multiple vertical heating tubes 154 are activated to preheat the raw materials. During this process, the second temperature sensor 125 monitors the temperature of the raw materials in the preheating tank 153 in real time.

[0033] Furthermore, when the temperature data monitored in real time by the second temperature sensor 125 is basically consistent with the temperature data of the mixture monitored in real time by the first temperature sensor 124, the first electronic valve 152 is briefly opened to pour the preheated raw materials into the mixing tank 10 through the feed pipe 151.

[0034] Furthermore, when water needs to be added, an external device is used to add water into the water bath 12 through the water inlet pipe 122. The water bath 12 heats the water inside to the temperature of the mixture monitored in real time by the first temperature sensor 124 and then outputs it from the water outlet pipe 123.

[0035] Furthermore, the pump 161 is started, pumping out heated water, which is then sprayed into the mixing tank 10 through the three-way pipe 164 and flange 162 from the two spray heads 163.

[0036] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 1 and 3, the mixing tank 10 includes an annular heating tube 101 wound inside the side wall, a discharge pipe 102 located at one end of the bottom of the mixing tank 10, and a second electronic valve 103 located at the output end of the discharge pipe 102.

[0037] It should be noted that the annular heating tube 101 is responsible for heating the inside of the mixing tank 10, and the outer shell of the mixing tank 10 should be made of heat-insulating material to prevent heat loss;

[0038] Furthermore, before mixing, the temperature of the annular heating tube 101 can be set via the control panel 121. When the specified temperature is reached in the mixing tank 10, the mixing process is carried out, and the temperature of each heating zone can be observed via the display screen on the control panel 121.

[0039] Furthermore, after the mixing process is completed, the second electronic valve 103 at the output end of the discharge pipe 102 is opened, and the mixture is discharged from the discharge pipe 102 into the mixing tank 10.

[0040] The working principle of this utility model is as follows:

[0041] First, before mixing, the temperature of the annular heating element 101 can be set via the control panel 121. The mixing process begins when the specified temperature is reached in the mixing tank 10. The temperature of each heating zone is observed on the display screen of the control panel 121. When raw materials need to be added, they must be added to the preheating tank 153 beforehand. Multiple vertical heating elements 154 are activated to preheat the raw materials. During this process, the second temperature sensor 125 monitors the temperature of the raw materials in the preheating tank 153 in real time. When the temperature data monitored by the second temperature sensor 125 is basically consistent with the temperature data of the mixture monitored by the first temperature sensor 124, the first electronic valve 152 is briefly opened, allowing the preheated raw materials to be poured into the mixing tank 10 through the feed pipe 151. When water needs to be added, water is added to the water bath 12 through the water inlet pipe 122 using an external device. After the internal water is heated to the temperature of the mixture as monitored in real time by the first temperature sensor 124, it is output from the outlet pipe 123. The pump 161 is started, pumping out the heated water, which is then sprayed into the mixing tank 10 through the three-way pipe 164 and the flange 162 from the two spray nozzles 163. When mixing is required after the materials are added, the drive motor 141 on the top of the tank cover 11 is started, and the high torque is output through the right angle reducer 142. The torque is used to drive the auger pipe 133 to rotate through the coupling 143. The auger pipe 133 rotates around the bearing seat 131 and the bearing pipe 132, stirring the materials in the mixing tank 10 to carry out the mixing process. When the device needs to be repaired, the coupling 143 is removed, and the tank cover 11 can be opened through the handle on the top of the tank cover 11. After the mixing process is completed, the second electronic valve 103 at the output end of the discharge pipe 102 is opened, and the mixture is discharged from the mixing tank 10 through the discharge pipe 102.

[0042] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
