Description

Technical Field

[0001] This utility model relates to a batching device, and more particularly to a batching device for fine chemical additives, belonging to the field of chemical additive production technology. Background Technology

[0002] Chemical additives are auxiliary chemicals added during chemical production and processing to improve production processes, enhance product performance, facilitate smooth processing, or endow products with specific functions. They are not "main raw materials" in production (such as resins in plastics, raw rubber in rubber, and film-forming substances in coatings), but although the amount used is small (usually accounting for a few percent or even a few ten-thousandths of the total product), they can significantly optimize production efficiency or product performance and are an indispensable key link in the chemical industry chain.

[0003] In the production of chemical additives, mixing tanks are used for mixing and preparation. To avoid cross-contamination during the mixing process, most mixing tanks are currently equipped with CIP (Cleaning in Place) systems for cleaning. However, during in-situ cleaning, the nozzles at the top of the mixing tank are in a fixed position, making it difficult to clean dead corners inside the tank (such as the bottom of the stirring shaft and the sealing surface of the manhole). Furthermore, the rinsing rate is slow for additives with strong adhesion, which affects the cleaning effect.

[0004] To address this issue, a fine chemical additive batching device was designed. Summary of the Invention

[0005] The main objective of this invention is to provide a fine chemical additive dispensing device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A fine chemical additive batching device includes a batching tank, a support leg vertically installed at the bottom of the batching tank, a manhole located on one side of the top of the batching tank, an observation window located on the other side of the top of the batching tank, a stirring motor vertically installed at the middle position of the top of the batching tank, and a stirring shaft installed at the output end of the stirring motor.

[0008] A funnel-shaped water cover is fixed to the top of the mixing tank, and the outer side of the funnel-shaped water cover is evenly provided with first water spray holes along the circumference.

[0009] A frustum-shaped water spray box is fixed at the middle position of the bottom of the mixing tank, and a second water spray hole is evenly opened on the outer side of the frustum-shaped water spray box along the circumference.

[0010] The stirring shaft passes through the inside of the funnel-shaped water cover and extends into the inside of the frustum-shaped spray tank, and the stirring shaft is rotatably connected to the funnel-shaped water cover and the frustum-shaped spray tank.

[0011] The inside of the stirring shaft is vertically provided with a vertical guide groove that connects the inside of the funnel-shaped water cover and the frustum-shaped spray box. The outside of the stirring shaft is evenly provided with a third spray hole that connects to the inside of the vertical guide groove.

[0012] A cleaning inlet pipe is provided on one side of the top of the mixing tank, which is connected to the inside of the funnel-shaped water hood.

[0013] Preferably, the third water spray hole at the top of the stirring shaft is inclined toward the top of the mixing tank, and the inclination angle of the third water spray hole on the stirring shaft gradually decreases from top to bottom until it is horizontal.

[0014] Preferably, an air pipe is installed on the top of the mixing tank away from the cleaning inlet pipe, the bottom end of the air pipe is connected to the inside of the funnel-shaped water cover, and a pressure gauge is installed on the air pipe.

[0015] Preferably, there is a gap between the bottom of the frustum-shaped water spray box and the inner bottom of the mixing tank, and a support plate is fixed between the bottom of the frustum-shaped water spray box and the inner bottom of the mixing tank.

[0016] Preferably, the first spray hole at the top of the outer side of the funnel-shaped water cover sprays water towards the top of the mixing tank, and the first spray hole at the bottom of the outer side of the funnel-shaped water cover sprays water downward in a fan shape.

[0017] Preferably, the second spray hole at the bottom of the outer side of the frustum-shaped water tank sprays water horizontally outward in a fan shape, while the second spray hole at the top of the outer side of the frustum-shaped water tank sprays water upward at an angle.

[0018] Preferably, the bottom of the funnel-shaped water cover and the top of the frustum-shaped spray tank are both equipped with sealing rings, and the sealing rings are in contact with the outer side of the stirring shaft.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves all-round rinsing through the coordinated operation of multiple components. The first spray hole on the funnel-shaped water cover can cover the top of the mixing tank and the upper area of ​​the stirring shaft. The second spray hole on the frustum-shaped spray box can spray upwards to specifically rinse the bottom of the stirring shaft and the bottom of the mixing tank. The third spray hole on the outside of the stirring shaft can rotate with the stirring shaft to perform flow rinsing on the inner wall of the mixing tank and the sealing surface of the manhole. This solves the problem of blind spots in cleaning caused by the fixed position of the nozzle in the traditional CIP system.

[0021] 2. This utility model, through the combined design of the cleaning inlet pipe and the air pipe, can introduce gas through the air pipe to form a gas-liquid mixture for rinsing. The airflow enhances the water pressure impact force, accelerating the peeling speed of strongly adhesive additive residues inside the tank. Compared with traditional single liquid rinsing, this structure can significantly shorten the rinsing time, improve the cleaning efficiency of stubborn stains, and ensure the cleanliness of the tank after cleaning. In addition, after cleaning, gas can be introduced separately through the air pipe and discharged from the first spray hole, the second spray hole, and the third spray hole to accelerate the drying inside the mixing tank.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a fine chemical additive batching device, including a batching tank 1, a support leg 101 vertically installed at the bottom of the batching tank 1, a manhole 102 provided on one side of the top of the batching tank 1, an observation window 103 provided on the other side of the top of the batching tank 1, a stirring motor 104 vertically installed at the middle position of the top of the batching tank 1, and a stirring shaft 105 installed at the output end of the stirring motor 104;

[0034] A funnel-shaped water cover 2 is fixed to the top of the inner part of the mixing tank 1, and the outer side of the funnel-shaped water cover 2 is evenly provided with first water spray holes 3 along the circumference.

[0035] A frustum-shaped water spray box 4 is fixed at the middle position of the bottom of the mixing tank 1, and a second water spray hole 5 is evenly opened on the outer side of the frustum-shaped water spray box 4 along the circumference.

[0036] The stirring shaft 105 passes through the inside of the funnel-shaped water cover 2 and extends into the inside of the frustum-shaped spray tank 4, and the stirring shaft 105 is rotatably connected to the funnel-shaped water cover 2 and the frustum-shaped spray tank 4.

[0037] The stirring shaft 105 has a vertically opening vertical guide groove 7 that connects the inside of the funnel-shaped water cover 2 and the frustum-shaped spray box 4. The stirring shaft 105 has a third spray hole 8 that is evenly opening on the outside of the stirring shaft 105 and connects to the inside of the vertical guide groove 7.

[0038] A cleaning inlet pipe 9 is provided on one side of the top of the mixing tank 1, which is connected to the inside of the funnel-shaped water cover 2.

[0039] During cleaning, the cleaning fluid enters the funnel-shaped water cover 2 through the cleaning inlet pipe 9. Part of the cleaning fluid is sprayed out circumferentially from the first spray hole 3 on the outside of the funnel-shaped water cover 2 to rinse the top and upper tank wall of the mixing tank 1. The other part of the cleaning fluid flows through the vertical guide groove 7 inside the stirring shaft 105 to the frustum-shaped spray box 4 and various sections of the stirring shaft 105. The cleaning fluid flowing into the frustum-shaped spray box 4 is sprayed out circumferentially from the second spray hole 5 on its outside to rinse the bottom and lower tank wall of the mixing tank 1. The cleaning fluid flowing into the vertical guide groove 7 of the stirring shaft 105 is sprayed out from the third spray hole 8 on its outside. At the same time, the stirring motor 104 drives the stirring shaft 105 to rotate, so that the third spray hole 8 rotates with the shaft to dynamically rinse the inner wall of the mixing tank 1 and the surface of the stirring shaft 105 itself. Through the fixed spray of the funnel-shaped water cover 2 and the frustum-shaped spray box 4 and the rotating spray of the stirring shaft 105, the mixing tank is cleaned in all directions without dead angles. Example 2

[0040] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0041] like Figure 2 As shown, in a preferred embodiment, based on the above method, the third water spray hole 8 at the top of the stirring shaft 105 is tilted toward the top of the mixing tank 1, and the tilt angle of the third water spray hole 8 on the stirring shaft 105 gradually decreases from top to bottom until it is horizontal.

[0042] The third water spray hole 8 at the top of the stirring shaft 105 is inclined toward the top of the mixing tank 1, which can specifically rinse the area on the top of the tank that is prone to dirt accumulation. From top to bottom, the inclination angle of the third water spray hole 8 gradually decreases until it is horizontal, so that the upper inclined water spray covers the upper and middle parts of the tank wall, and the lower horizontal water spray covers the lower part of the tank wall and the lower and middle sections of the stirring shaft 105. With the rotation of the stirring shaft 105, the cleaning coverage area is further expanded, avoiding cleaning blind spots in different height areas of the tank wall.

[0043] like Figure 1 As shown, in a preferred embodiment, based on the above method, an air pipe 10 is further installed on the top of the mixing tank 1 away from the cleaning inlet pipe 9. The bottom end of the air pipe 10 is connected to the inside of the funnel-shaped water cover 2, and a pressure gauge is provided on the air pipe 10.

[0044] The air pipe 10 is connected to the inside of the funnel-shaped water cover 2. During cleaning, compressed gas can be introduced into the funnel-shaped water cover 2 through the air pipe 10. The gas pressure increases the fluid pressure inside the water cover, thereby increasing the spray intensity of the first water spray hole 3, the second water spray hole 5, and the third water spray hole 8, and enhancing the removal effect on stubborn stains. The pressure gauge on the air pipe 10 can monitor the pressure inside the water cover in real time to ensure that the cleaning pressure is stable within the effective range. After cleaning, compressed air can be introduced and discharged from the first water spray hole 3, the second water spray hole 5, and the third water spray hole 8 to quickly dry the water stains inside the mixing tank 1.

[0045] like Figure 2 As shown, in a preferred embodiment, based on the above method, a gap is left between the bottom end of the frustum-shaped water spray box 4 and the inner bottom of the mixing tank 1, and a support plate 6 is fixed between the bottom end of the frustum-shaped water spray box 4 and the inner bottom of the mixing tank 1.

[0046] The bottom of the frustum-shaped spray tank 4 is spaced from the bottom of the mixing tank 1, so that the cleaning liquid sprayed from the second spray hole 5 can flow to the edge area of ​​the tank bottom, avoiding the formation of a cleaning dead corner at the contact point between the tank bottom and the spray tank. The support plate 6, while ensuring the spacing, also fixes the frustum-shaped spray tank 4 to prevent it from shifting under the spray pressure.

[0047] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the first water spray hole 3 at the top of the outer side of the funnel-shaped water cover 2 sprays towards the top of the mixing tank 1, with the top hole inclined upward at 45° to the horizontal direction (towards the top of the tank), and the first water spray hole 3 at the bottom of the outer side of the funnel-shaped water cover 2 sprays downward in a fan shape, with the bottom hole inclined downward at 30° to the horizontal direction (fan-shaped spray angle 60°), ensuring coverage of the top of the tank and the upper tank wall within a range of 1.5m.

[0048] The first water spray hole 3 at the top of the outer side of the funnel-shaped water cover 2 faces the top of the mixing tank 1, which can accurately rinse the top area of ​​the tank and the sealing surface of the manhole 102, which are prone to dirt accumulation. The first water spray hole 3 at the bottom of the outer side sprays downward in a fan shape, which can cover the upper tank wall of the mixing tank 1 and the upper surface of the stirring shaft 105, so as to achieve layered and comprehensive rinsing of the top and upper areas inside the tank.

[0049] like Figure 4 As shown, in a preferred embodiment, based on the above method, the second water spray hole 5 at the bottom of the outer side of the frustum-shaped water tank 4 sprays horizontally outward in a fan shape, the second water spray hole 5 at the top of the outer side of the frustum-shaped water tank 4 sprays upward at an angle, the bottom hole is horizontally outward (fan angle 90°), and the top hole is inclined upward at 60° with the horizontal direction, covering the bottom of the tank and the lower part of the tank wall within a 1m range.

[0050] The second water spray hole 5 at the bottom of the outer side of the frustum-shaped water spray box 4 sprays horizontally outward in a fan shape, which can cover the bottom edge and corners of the mixing tank 1. The second water spray hole 5 at the top of the outer side sprays upward at an angle, which can wash the lower tank wall and the lower surface of the stirring shaft 105. Through the upper and lower layered water spraying, the bottom of the tank and the lower area can be cleaned without dead angles.

[0051] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the bottom end of the funnel-shaped water cover 2 and the top end of the frustum-shaped spray tank 4 are both provided with sealing rings, and the sealing rings are in contact with the outer side of the stirring shaft 105.

[0052] The sealing rings at the bottom of the funnel-shaped water cover 2 and the top of the frustum-shaped spray tank 4 are in contact with the outside of the stirring shaft 105, which can prevent the cleaning fluid from leaking from the rotating connection between the stirring shaft 105 and the water cover and spray tank, ensuring the pressure inside the funnel-shaped water cover 2 and the frustum-shaped spray tank 4, and ensuring the spray intensity and cleaning effect of each spray hole.

[0053] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
