Description

Technical Field

[0001] The utility model belongs to the technical field of silica gel production, and in particular relates to a material feeding device for silica gel production. Background Art

[0002] Silica gel is a granular porous silicon dioxide hydrate, which is made by adding acid to sodium silicate, followed by washing and drying. It is transparent or milky white in appearance and has an open porous structure, so it has strong adsorption properties and can adsorb a variety of substances.

[0003] In the production process of silicone, liquid silicone is sometimes needed, so it is necessary to feed the liquid silicone. At this time, the operator will use a feeding device to transport the liquid silicone, and use the pump body on the feeding device to transport the liquid silicone in the storage box to the required place. Because liquid silicone will be affected by changes in ambient temperature, the viscosity of the liquid silicone will change. If the liquid silicone is left in the storage box for a long time, the viscosity may increase, which will cause the pump body to fail to transport the liquid silicone well, thereby affecting the normal feeding operation of the feeding device.

[0004] Therefore, the utility model provides a feeding device for silica gel production materials to solve the above problems. Utility Model Content

[0009] In order to ensure that the liquid silica gel in the storage box can be discharged normally, as a preferred feeding device for silica gel production materials of the utility model, the position of the internal space of the storage box is connected to the position of the internal space of the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model cooperates with each other among the temperature sensor, the heat conductive block, the heating block, the motor and the stirring rod. When the temperature sensor detects that the temperature of the liquid silicone in the storage box does not meet the standard, the PLC control switch will start the heating block, so that the heating block heats the heat conductive block. In this way, the temperature of the liquid silicone will rise when it contacts the surface of the heat conductive block. The liquid silicone can be stirred by the stirring rod to increase the temperature of the liquid silicone in the storage box, thereby ensuring the fluidity of the liquid silicone and preventing the increase of the viscosity of the liquid silicone from affecting the feeding operation.

[0023] Preferably: the exhaust mechanism includes: an air intake pipe 15, a vacuum pump 16, a delivery pipe 17, a filter bin 18, an activated carbon filter element 19 and a one-way valve 20. The top surface of the storage box 1 is penetrated by an air intake pipe 15, the other end of the air intake pipe 15 is connected to the output end of the vacuum pump 16, the output end of the vacuum pump 16 is connected to the delivery pipe 17, the other end of the delivery pipe 17 extends into the filter bin 18, the installation groove opened on the top surface of the filter bin 18 is connected to the activated carbon filter element 19, and the other side surface of the filter bin 18 is connected to the one-way valve 20.

[0024] During specific use, start the vacuum pump 16 and let the vacuum pump 16 transport the gas in the storage box 1 from the delivery pipe 17 to the filter bin 18 through the suction pipe 15. When the transported gas enters the filter bin 18, the activated carbon filter element 19 installed on the filter bin 18 will adsorb and filter the gas in the filter bin 18, so that the harmful substances in the gas will adsorb the activated carbon filter element 19, so that the filtered gas can be discharged from the one-way valve 20.

[0033] Working principle: When using the feeding device for silicone production materials, install the feeding device at the specified position, and then connect the liquid silicone raw material delivery pipe to the feeding pipe 2, so that liquid silicone can be added to the storage box 1. When the liquid level sensor 4 detects that the liquid silicone in the storage box 1 is stored in the specified position, the PLC control switch will close the solenoid valve 3 to avoid further adding liquid silicone to the storage box 1. At the same time, when the liquid level sensor 4 detects that the liquid silicone in the storage box 1 is insufficient, the PLC control switch will open the solenoid valve 3 again to add liquid silicone. The operator can use the peristaltic pump 6 to transport the liquid silicone in the storage box 1 from the feeding pipe 7 to the specified position through the discharge pipe 5, thereby completing the feeding operation of the liquid silicone. When the temperature sensor 9 detects that the temperature of the liquid silicone in the storage box 1 is not within the specified range, the PLC control switch will start the heating block 11, so that the heating block 11 starts heating, thereby transferring heat to the heat-conducting block 10, so that the temperature of the heat-conducting block 10 rises, so that the liquid silicone in the storage box 1 will contact one side surface of the heat-conducting block 10, so that the temperature of the liquid silicone contacting the surface of the heat-conducting block 10 will rise. The liquid silicone in the material storage box 1 is stirred by the stirring rod 13, so that the liquid silicone can be evenly contacted with the surface of the heat conductive block 10, and the temperature of the liquid silicone in the material storage box 1 is increased to a specified range, so as to avoid the problem of increased viscosity of the liquid silicone in the material storage box 1 due to the low ambient temperature, which affects the normal feeding operation of the feeding device. , gas will be generated in the storage box 1. In order to avoid excessive air pressure in the storage box 1, the vacuum pump 16 will be started to allow the vacuum pump 16 to transport the gas in the storage box 1 from the delivery pipe 17 to the filter bin 18 through the suction pipe 15. When the transported gas enters the filter bin 18, the activated carbon filter element 19 installed on the filter bin 18 will adsorb and filter the gas in the filter bin 18, so that the harmful substances in the gas will adsorb the activated carbon filter element 19, so that the filtered gas can be discharged from the one-way valve 20, avoiding direct discharge of the gas without filtration, thereby causing pollution to the working environment.
