Description

Technical Field

[0001] This application relates to the field of alkali mixing tank production, and in particular to an alkali mixing tank for tea pigment production. Background Technology

[0002] In the production process of tea pigments, it is often necessary to adjust the pH value of the chemical solution, which usually depends on ethanol or sodium hydroxide solution. Therefore, an alkali mixing tank is required in the production of tea pigments.

[0003] Sodium hydroxide solution is highly alkaline and corrosive, resulting in a short service life for alkali mixing tanks. Since alkali mixing tanks are equipped with many supporting devices, replacing them due to corrosion will result in significant economic losses.

[0004] Therefore, it is necessary to propose an alkali mixing tank for tea pigment production, which can reduce the economic losses caused by replacing the alkali mixing tank, and this has become an important technical problem that needs to be solved urgently. Utility Model Content

[0005] This application provides an alkali mixing tank for tea pigment production, aiming to solve the problems in the prior art where the alkali mixing tank has a short service life due to the strong alkalinity and corrosiveness of sodium hydroxide solution, and where the replacement of the alkali mixing tank due to corrosion results in significant economic losses because the tank has many supporting devices.

[0006] To achieve the above objectives, this application proposes an alkali mixing tank for tea pigment production, comprising: an inner cylinder; a lower end cap disposed at the bottom of the inner cylinder and integrally formed with the inner cylinder; an upper end cap detachably installed at the top of the inner cylinder; a liquid inlet disposed at the upper end cap; a hand hole disposed at the upper end cap; and a discharge outlet disposed at the lower end cap.

[0007] In some embodiments, the device further includes: a stirring drive disposed on the upper end cap; and stirring blades disposed within the inner cylinder, wherein the stirring drive drives the stirring blades to rotate.

[0008] In some embodiments, the device further includes: a connecting shaft disposed on the upper end cap and connected to a stirring drive; an upper connector disposed at the end of the connecting shaft; a stirring shaft with stirring blades spaced apart on the outer circumferential surface of the stirring shaft; and a lower connector disposed at the end of the stirring shaft, wherein the upper connector and the lower connector are connected together by fasteners.

[0009] In some embodiments, the device further includes: a sight glass disposed at the top of the upper end cap; and a sight lamp disposed at the top of the upper end cap.

[0010] In some embodiments, the device further includes: a flushing port disposed at the top of the upper end cap; and a venting port disposed at the top of the upper end cap.

[0011] In some embodiments, the device further includes a cleaning port located at the top of the tank.

[0012] This application proposes an alkali mixing tank for tea pigment production, comprising: an inner cylinder; a lower end cap, integrally formed with the inner cylinder, located at the bottom end of the inner cylinder; an upper end cap, detachably mounted at the top end of the inner cylinder; a liquid inlet, located on the upper end cap; a manhole, located on the upper end cap; and a discharge outlet, located on the lower end cap. During the preparation of the sodium hydroxide solution, purified water flows into the inner cylinder from the liquid inlet. The manhole is opened, and sodium hydroxide is added into the inner cylinder. After the sodium hydroxide is added, the manhole is closed. The sodium hydroxide solution is then mixed and formed within the inner cylinder and discharged from the discharge outlet. During the mixing process, only the lower end cap and the inner liner are in contact with the sodium hydroxide solution, while the upper end cap and its various components are not in contact with the sodium hydroxide solution. Furthermore, sodium hydroxide is not volatile, resulting in minimal corrosion of the upper end cap. When the lower end cap and the inner liner are severely corroded and require replacement, only the lower end cap and the inner liner need to be replaced, thus saving the economic cost of replacing the alkali mixing tank.

[0023] See Figure 1 As shown, this application proposes an alkali mixing tank for tea pigment production, comprising: an inner cylinder 3; a lower end cap 2, which is disposed at the bottom end of the inner cylinder 3 and is integrally formed with the inner cylinder 3; an upper end cap 4, which is detachably installed at the top end of the inner cylinder 3; a liquid inlet 8, which is disposed on the upper end cap 4; a hand hole 5, which is disposed on the upper end cap 4; and a discharge port 13, which is disposed on the lower end cap 2.

[0024] The main structure of the alkali mixing tank consists of an upper end cap 4, an inner liner 3, and a lower end cap 2. The inner liner 3 and the lower end cap 2 are integrally formed. The upper end cap 4 is detachably installed onto the inner liner 3. Specifically, the bottom end of the upper end cap 4 is provided with a first connecting end 9, and the top end of the inner liner 3 is provided with a second connecting end 10. Both the first connecting end 9 and the second connecting end 10 are provided with threaded holes. Bolts pass through the threaded holes on the first connecting end 9 and the second connecting end 10, thereby installing the upper end cap 4 onto the inner liner 3. The liquid inlet 8 is used to put pure water into the inner liner 3, and the hand hole 5 is used to add sodium hydroxide material into the inner liner 3. After the sodium hydroxide solution is mixed and formed in the inner liner 3, it is discharged from the discharge port 13.

[0025] Specifically, during the preparation of the sodium hydroxide solution, purified water flows into the inner cylinder 3 through the inlet 8. The manhole 5 is opened, and sodium hydroxide material is added into the inner cylinder 3. After adding the sodium hydroxide material, the manhole 5 is closed. The sodium hydroxide solution is prepared and formed inside the inner cylinder 3 and then discharged from the outlet 13. During the preparation process, only the lower end cap 2 and the inner cylinder 3 come into contact with the sodium hydroxide solution, while the upper end cap 4 and its various components do not come into contact with the sodium hydroxide solution. Furthermore, sodium hydroxide is not volatile, resulting in minimal corrosion of the upper end cap 4. When the lower end cap 2 and the inner cylinder 3 become severely corroded and need to be replaced, only the lower end cap 2 and the inner cylinder 3 need to be replaced, saving the economic cost of replacing the alkali preparation tank.

[0026] Among them, the inner cylinder 3, the lower end cap 2 and the upper end cap 4 are all made of chromium-nickel stainless steel. Chromium-nickel stainless steel has good mechanical properties and corrosion resistance, which enables an alkali mixing tank for tea pigment production to adapt to diverse and harsh operating environments.

[0027] Preferably, the inner cylinder 3 is provided with multiple support feet 1. The handhole 5 is provided with a handle 20, which facilitates the opening and closing of the handhole 5.

[0028] See Figure 1 As shown, in some embodiments, it further includes: a stirring drive 6, which is disposed on the upper end cap 4; the stirring drive 6 is a motor, and the stirring blades 12 are disposed inside the inner liner 3. The stirring drive 6 drives the stirring blades 12 to rotate. The stirring drive 6 drives the stirring blades 12 to rotate, stirring the liquid inside the inner liner 3, so that the sodium hydroxide material can be fully mixed with the pure water, improving the homogeneity of the sodium hydroxide material and the pure water, and avoiding excessive local heat.

[0029] In this embodiment, the outer surface of the stirring blade 12 is provided with an anti-corrosion coating to improve the service life of the stirring blade 12.

[0030] See Figure 1 and Figure 2As shown, in some embodiments, the system further includes: a connecting shaft 7, which is disposed on the upper end cap 4 and connected to a stirring drive 6; the stirring drive 6 has an output end, which is connected to the connecting shaft 7 via a coupling, thereby driving the connecting shaft 7 to rotate; an upper connecting member 15, which is disposed at the end of the connecting shaft 7; the upper connecting member 15 is disposed at the end of the connecting shaft 7 away from the stirring drive 6; a stirring shaft 11, with stirring blades 12 spaced apart on the outer circumferential surface of the stirring shaft 11; and a lower connecting member 14, which is disposed at the end of the stirring shaft 11, and the upper connecting member 15 and the lower connecting member 14 are connected together by fasteners. The lower connecting member 14 is disposed at the end of the stirring shaft 11 away from the stirring blades 12. Both the lower connecting member 14 and the upper connecting member 15 are provided with threaded holes, and bolts pass through the threaded holes on the lower connecting member 14 and the upper connecting member 15 to achieve the connection between the lower connecting member 14 and the upper connecting member 15, thereby achieving the connection between the connecting shaft 7 and the stirring shaft 11. Because the stirring shaft 11 and stirring blade 12 are in contact with sodium hydroxide solution for a long time, their service life is short. When the stirring shaft 11 and stirring blade 12 are damaged, they can be replaced individually to reduce economic losses.

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the device further includes: a sight glass 17, which is disposed at the top of the upper head 4; the sight glass 17 is used to observe the inside of the alkali mixing tank; and a sight lamp 18, which is disposed at the top of the upper head 4. The sight lamp 18 is used to provide a light source to facilitate observation of the inside of the alkali mixing tank by the staff.

[0032] See Figure 1 and Figure 3 As shown, in some embodiments, the system further includes: a rinsing port 16, which is located at the top of the upper head 4; the rinsing port 16 is connected to a rinsing liquid source, allowing the alkali mixing tank to be quickly rinsed through the rinsing liquid source and the rinsing port 16 after the sodium hydroxide solution has been prepared; and a venting port 19, also located at the top of the upper head 4. Since the preparation of the sodium hydroxide solution generates a significant temperature rise, leading to increased internal pressure in the alkali mixing tank, the venting port 19 helps to balance the internal and external pressures, preventing excessive pressure inside the alkali mixing tank.

[0033] See Figure 1 and Figure 4 As shown, in some embodiments, it also includes a sponge 21, which is disposed inside the vent 19. The vent 19 is mainly used to release water vapor, and the sponge 21 is used to absorb water vapor, so as to avoid seeing obvious white water mist in the vent 19, and at the same time, to prevent the humidity in the mixing room from being too high.

[0034] In this embodiment, the vent 19 is provided with a placement platform and a snap-fit ​​surface. The placement platform abuts against the bottom surface of the sponge 21, and the snap-fit ​​surface abuts against the top surface of the sponge 21. The top of the sponge 21 is provided with a rigid protrusion 22. The rigid protrusion 22 facilitates easy removal and replacement of the sponge 21.

[0035] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
