Due to the special properties of corrosive liquids, uneven addition may cause local over-reaction or under-reaction, thereby affecting product quality and production stability. In view of this, the present utility model is specially proposed. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0019] Example 1:
[0020] Reference Figure 1-Figure 3 The corrosive liquid material feeding device includes a feeding bin 2001, which is integrally connected to the lower end of the kettle cover 2. A storage chamber 201 and a feeding chamber 202 are provided inside the feeding bin 2001. The feeding chamber 202 is located outside the storage chamber 201. A circle of through-holes 204 are provided between the feeding chamber 202 and the storage chamber 201. The kettle cover 2 is connected to a feeding pipe 2002 connected to the storage chamber 201, and further includes: an annular plate 205, which is sealingly and slidingly connected to the feeding chamber 202. ; The barrier ring plate 206 is fixedly connected to the side of the upper end of the annular plate 205 close to the through-hole 204, and the barrier ring plate 206 is sealed and slidably connected to the inner wall of the feeding chamber 202; the spray head 207 is fixedly connected to the bottom of the feeding bin 2001 at equidistant intervals around the circumference, and the feeding chamber 202 is provided with a discharge port connected to the spray head 207 at the lower end, and a one-way valve is installed in the discharge port; the drive assembly for controlling the up and down movement of the annular plate 205 in the feeding chamber 202 is installed on the kettle cover 2, and the one-way valve is not shown in the figure.
[0021] The driving assembly includes an electric telescopic rod 3, a connecting plate 301 and a vertical rod 302. The electric telescopic rod 3 is symmetrically fixedly connected to both sides of the upper end of the kettle cover 2. The connecting plate 301 is fixedly connected to the telescopic ends of the two electric telescopic rods 3. The vertical rods 302 are fixedly connected to the lower surface of the connecting plate 301 at equal intervals around the circumference. The lower end of the vertical rod 302 extends downward into the feeding chamber 202 and is fixedly connected to the annular plate 205.
[0022] When it is necessary to add corrosive liquid materials into the reactor 1, the staff first adds a certain amount of corrosive liquid materials into the storage chamber 201 through the feeding pipe 2002, and then starts the electric telescopic rod 3, so that the electric telescopic rod 3 drives the annular plate 205 to move upward through the connecting plate 301 and the vertical rod 302, so that the annular plate 205 moves up to above the through-hole 204, and then the corrosive liquid materials in the storage chamber 201 will flow into the feeding chamber 202 through the through-hole 204, and then the electric telescopic rod 3 can be started again, so that the electric telescopic rod 3 drives the annular plate 205 to move downward through the connecting plate 301 and the vertical rod 302, and then the excess corrosive liquid materials in the feeding chamber 202 will flow back into the storage chamber 201 through the through-hole 204 under the action of the downward squeezing of the annular plate 205, thereby realizing the quantitative feeding of the corrosive liquid materials and ensuring the accuracy of the feeding. Accuracy, when the annular plate 205 continues to move downward, the corrosive liquid material in the feeding chamber 202 will push open the one-way valve, and then the corrosive liquid material will be sprayed into the material in the reactor 1 through the spray head 207, and when the annular plate 205 moves down to the bottom of the through-hole 204, the blocking ring plate 206 will block the through-hole 204 to prevent the corrosive liquid material from flowing to the top of the annular plate 205 and causing waste. Through the setting of this feeding device, compared with the feeding method of simple pipeline transportation or direct pouring in the prior art, not only can the quantitative feeding of corrosive liquid materials be achieved, but also the corrosive liquid materials can be evenly added to the materials in the reactor 1 in a spraying manner, avoiding the problem of local over-reaction or under-reaction due to uneven feeding, thereby affecting product quality and production stability, and effectively improving practicality.
[0023] Example 2:
[0024] Reference Figure 1-Figure 3 The corrosive liquid material feeding device is basically the same as that of Example 1, and furthermore, the kettle cover 2 is installed on the reactor 1 through a connecting piece, and the kettle cover 2 is fixedly connected to the motor 101. The output end of the motor 101 is fixedly connected to the rotating shaft 102, and the rotating shaft 102 downwardly penetrates the storage chamber 201 and extends into the reactor 1. The lower end of the rotating shaft 102 extending into the reactor 1 is fixedly connected to multiple rows of stirring plates 103, and the position of the rotating shaft 102 near the spray head 207 is fixedly connected to multiple disturbance plates 105 at equal intervals on the circumference, and the spray port of the spray head 207 faces obliquely downward toward the position where the disturbance plates 105 are located.
[0025] When the motor 101 drives the stirring plate 103 to stir the material in the reactor 1 through the rotating shaft 102, and at the same time, corrosive liquid material is added to the material through the spray head 207, the rotating shaft 102 can simultaneously drive the disturbance plate 105 to rotate. By making the spray port of the spray head 207 obliquely downward toward the position of the disturbance plate 105, when the spray head 207 sprays the corrosive liquid material into the material in the reactor 1, the disturbance plate 105 can break up the sprayed corrosive liquid material, thereby facilitating more uniform spraying of the corrosive liquid material, further improving the uniformity of mixing between the corrosive liquid material and the material previously added to the reactor 1, and avoiding the problem of affecting product quality and production stability due to excessive or insufficient local reaction.
[0026] Example 3:
[0027] Reference Figure 1-Figure 3 The corrosive liquid material feeding device is basically the same as that of Example 2, and further, a seal 203 is fixedly connected to the position where the rotating shaft 102 is rotatably connected to the kettle cover 2 and the feeding bin 2001. Through the setting of the seal 203, the sealing between the rotating shaft 102 and the kettle cover 2 and the feeding bin 2001 can be improved to avoid the risk of leakage of corrosive liquid materials. This not only improves the safety of the device during use, but also avoids the problem of excessive addition of materials due to leakage of corrosive liquid materials.
[0028] The lower end of the interior of the storage chamber 201 is designed to be arc-shaped, and a plurality of paddles 104 are fixedly connected to the rotating shaft 102 at equal intervals on the circumference. The lower end surface of the paddle 104 slides against the arc-shaped surface of the lower end of the storage chamber 201. Through the arrangement of the paddle 104, when the liquid level of the corrosive liquid material in the storage chamber 201 is lower than the through-port 204, the rotation of the rotating shaft 102 can easily drive the paddle 104 to paddle the corrosive liquid material, so that the corrosive liquid material with a lower liquid level can be paddled into the feeding chamber 202 through the through-port 204, thereby improving the utilization rate of the corrosive liquid material. At the same time, the rotating paddle 104 can also stir and mix the corrosive liquid material, thereby improving the uniform mixing of the various components inside the corrosive liquid material and ensuring the quality of the corrosive liquid material.
[0029] The surfaces of the reactor 1, the rotating shaft 102, the stirring plate 103, the disturbance plate 105, the dial plate 104, the reactor cover 2, the feeding bin 2001, the feeding pipe 2002 annular plate 205, the barrier ring plate 206, the spray head 207 and the seal 203 that are in contact with the corrosive liquid material are all provided with an anti-corrosion coating. By performing anti-corrosion treatment on the surfaces of the feeding device and the reactor 1 that are in contact with the corrosive liquid material, the corrosion rate of the device and the reactor 1 by the corrosive liquid material can be reduced, thereby effectively improving the service life of the device and the reactor 1.
[0030] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
