Description

Technical Field

[0001] This utility model relates to the field of sodium tungstate production technology, and in particular to a pollution-proof sodium tungstate purification machine. Background Technology

[0002] Sodium tungstate is an inorganic substance with the chemical formula Na2WO4. It is a colorless crystal or white crystalline powder that effloresces in dry air and loses its water of crystallization at 100°C. It is soluble in water but insoluble in ethanol. Its relative density is 3.23–3.25, and its melting point is 698°C (anhydrous). Currently, heating and stirring are essential steps in the purification process of sodium tungstate.

[0003] Traditional heating and stirring devices mostly heat the stirring tank directly through heating resistance wires. This heating method tends to result in uneven heating, where the side of the heating tank with the heating resistance wire wrapped around it is at a higher temperature and the side further away from the heating resistance wire is at a lower temperature. This affects the purification quality and is therefore inconvenient to use, thus failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided a pollution-resistant sodium tungstate purification machine to solve the problems mentioned in the background art. Utility Model Content

[0005] To improve the problem of uneven heating, this invention provides a pollution-proof sodium tungstate purification machine.

[0006] This utility model provides a pollution-proof sodium tungstate purification machine, which adopts the following technical solution:

[0007] A pollution-resistant sodium tungstate purification machine includes a heating chamber. A material box is embedded in the top of the heating chamber. A drive box is fixedly connected to the top of the material box. A rotating shaft is rotatably connected to the left and right sides of the top of the drive box via bearings. The bottom of the rotating shaft passes through the material box and extends to the bottom of the material box's inner cavity. Stirring plates are fixedly connected to the upper and lower positions of the left and right sides of the rotating shaft. A drive assembly is installed at the center of the top of the heating chamber and within the drive box's inner cavity. Electric heating tubes are fixedly connected to the bottom of the left and right sides of the heating chamber's inner cavity. A water temperature sensor is fixedly installed on the left side of the heating chamber's inner cavity. A PLC controller and a relay are fixedly installed sequentially from top to bottom on the left side of the heating chamber. A discharge pipe is connected to the bottom of the material box. The bottom of the discharge pipe passes through the heating chamber and connects to a filter cylinder. A filter screen is fixedly connected to the inner cavity of the filter cylinder. A pipe cap is threadedly connected to the right side of the filter cylinder.

[0008] By adopting the above technical solution, when the temperature of the water in the heating chamber is lower than the preset value of the water temperature sensor, the water temperature sensor transmits data to the PLC controller. The PLC controller then processes the data and activates the electric heating tubes on both sides of the relay, allowing the electric heating tubes to heat the water in the heating chamber, thereby increasing the temperature of the water in the heating chamber. At the same time, the water heats the material box evenly, thus allowing the material box to heat the raw materials evenly. Simultaneously, the operator starts the external controller of the rotary motor, causing the output end of the rotary motor to drive the drive gear to rotate. The drive gear drives the driven gears on both sides to rotate, and the driven gears drive the rotating shaft to rotate, causing the rotating shaft to drive the stirring plate to rotate, thereby causing the stirring plate to stir the raw materials.

[0009] When the water temperature inside the heating chamber reaches the preset value of the water temperature sensor, the water temperature sensor transmits the data to the PLC controller. The PLC controller then processes the data and causes the relay to shut off the electric heating tube, so that the temperature of the raw materials is always kept within the specified reaction temperature range, allowing it to react fully and completely.

[0010] Optionally, the drive assembly includes a rotary motor, the bottom of which is fixedly connected to the connection of the material box, a drive gear is fixedly connected to the output end of the rotary motor, and a driven gear is fixedly connected to the outer surface of the rotating shaft, wherein the drive gear and the driven gear mesh.

[0011] By adopting the above technical solution, the arrangement of the rotary motor, the driving gear, and the driven gear facilitates the rotation of the shaft.

[0012] Optionally, slide cylinders are embedded on both the left and right sides of the top of the material box, and the inner surface of the slide cylinders is rotatably connected to the outer surface of the rotating shaft.

[0013] By adopting the above technical solution, the slide can be conveniently used to guide and support the rotating shaft.

[0014] Optionally, a feed pipe is connected to the top of the material box and the front of the drive box, and a water supply pipe is connected to the right side of the top of the heating box.

[0015] By adopting the above technical solution, the feed pipe can facilitate the entry of raw materials into the inner cavity of the feed box, and the water supply pipe can facilitate the addition of water to the inner cavity of the heating box.

[0016] Optionally, a solenoid valve is provided on the outer surface of the discharge pipe, and a discharge pipe is connected to the left side of the bottom of the filter cylinder.

[0017] By adopting the above technical solution, the solenoid valve can be conveniently opened and closed, and the discharge pipe can be conveniently transported and discharged.

[0018] Optionally, brackets are fixedly connected to the left and right sides of the top of the filter cartridge, and the top of the brackets is fixedly connected to the bottom of the heating box.

[0019] By adopting the above technical solution, the bracket can be used to connect and install the filter cartridge and the heating box.

[0020] Optionally, a protective box is fixedly connected to the left side of the heating box, and the PLC controller and relay are located inside the protective box.

[0021] By adopting the above technical solution, the protective box can be conveniently used to protect the PLC controller and relays.

[0022] Optionally, support legs are fixedly connected to the four corners of the bottom of the heating box, and rubber pads are fixedly connected to the bottom of the support legs.

[0023] By adopting the above technical solution, the support legs and rubber pads can provide support for the device.

A solenoid valve 16 is provided on the outer surface of the discharge pipe 11. A discharge pipe 17 is connected to the left side of the bottom of the filter cylinder 12. A bracket is fixedly connected to both sides of the top of the filter cylinder 12, and the top of the bracket is fixedly connected to the bottom of the heating box 1.

[0037] In this embodiment: By setting up a heating box 1, a material box 2, an electric heating tube 7, a water temperature sensor 8, a PLC controller 9, and a relay 10, the present invention can uniformly heat the raw materials in the inner cavity of the material box 2. By setting up a drive box 3, a rotating shaft 4, a stirring plate 5, and a drive assembly 6, the raw materials can be uniformly stirred.

By setting up the above structure, the raw materials can be uniformly heated in a convenient way, thereby meeting the customer's usage needs.

[0038] Example 2:

[0039] Reference Figure 2 , Figure 3 and Figure 4 The drive assembly 6 includes a rotary motor 601. The bottom of the rotary motor 601 is fixedly connected to the connection of the material box 2. The output end of the rotary motor 601 is fixedly connected to a drive gear 602. The outer surface of the rotating shaft 4 is fixedly connected to a driven gear 603. The drive gear 602 and the driven gear 603 mesh.

[0040] In this embodiment: By setting up a drive box 3, a rotating shaft 4, a stirring plate 5, a rotary motor 601, a driving gear 602 and a driven gear 603, the present invention can uniformly stir the raw materials and further uniformly heat the raw materials.

[0041] The implementation principle of this utility model is as follows: In use, the operator connects the device to the mains power supply. Then, the operator sequentially feeds the raw materials into the inner cavity of the material box 2 through the feed pipe. At the same time, when the temperature of the water in the inner cavity of the heating box 1 is lower than the preset value of the water temperature sensor 8, the water temperature sensor 8 transmits the data to the PLC controller 9. The PLC controller 9 then processes the data and causes the relay 10 to turn on the electric heating tubes 7 on both sides, so that the electric heating tubes 7 heat the water in the inner cavity of the heating box 1, thereby increasing the temperature of the water in the inner cavity of the heating box 1. At the same time, the water heats the material box 2 evenly, so that the material box 2 heats the raw materials evenly. Meanwhile, the operator starts the external controller of the rotary motor 601, so that the output end of the rotary motor 601 drives the drive gear 602 to rotate. The drive gear 602 drives the driven gears 603 on both sides to rotate. The driven gears 603 drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the stirring plate 5 to rotate, so that the stirring plate 5 stirs the raw materials.

[0042] When the water temperature inside the heating chamber 1 reaches the preset value of the water temperature sensor 8, the water temperature sensor 8 transmits the data to the PLC controller 9. The PLC controller 9 then processes the data and causes the relay 10 to turn off the electric heating tube 7, so that the temperature of the raw material is always kept within the specified reaction temperature range, allowing it to react fully and completely.

[0043] After the raw materials have reacted completely, the operator opens the solenoid valve 16, allowing the reacted raw materials to enter the inner cavity of the filter cylinder 12 through the discharge pipe 11. At the same time, the filter screen 13 filters the reactants, and the filtrate is discharged through the discharge pipe 17 and transported to the next process for concentration, cooling and other purification treatments. The device is simple to operate and easy to use for uniform heating, thus meeting the needs of customers.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
