Description

Technical Field

[0001] The invention relates to the technical field of stirring tanks, and more specifically, to a chemical stirring tank. Background Art

[0002] Chemical adhesives are a type of chemical widely used in industry and daily life. They can firmly bond different materials together. Chemical adhesives are usually prepared by mixing and stirring in a chemical mixing tank. In the preparation process of chemical adhesives, degassing is a very important step. Bubbles will reduce the bonding strength of the adhesive because bubbles form gaps in the adhesive, reducing the effective bonding area; bubbles will also reduce the durability and life of the adhesive because bubbles form weak points inside the adhesive, which can easily become stress concentration points; at the same time, bubbles will also destroy the sealing and waterproof properties of the adhesive, leading to moisture and gas penetration.

[0003] At present, the methods for degassing chemical adhesives mainly include: heating degassing, vacuum degassing and centrifugal degassing. In the centrifugal degassing process, the adhesive is placed in a rotating container. Due to the action of centrifugal force, the bubbles with light specific gravity will float to the surface of the liquid and burst to achieve the degassing effect, but this degassing method still has certain defects: 1. Although the bubbles in the adhesive will float up under the action of centrifugal force, large bubbles will float up faster under the action of centrifugal force and are easy to be separated and discharged, but for smaller bubbles, the floating speed is slow and may not be able to completely float to the adhesive surface in a short time, and the overall floating speed of bubbles in high-viscosity adhesives is slow.

[0004] 2. Since the bubbles in some adhesives contain surfactants that are not easy to burst, the bubbles will not burst quickly after floating to the surface of the adhesive, so it takes a longer time to carry out continuous centrifugal degassing to completely eliminate the bubbles in the adhesive, which leads to the need to improve the degassing effect. Summary of the invention

[0005] The invention provides a chemical stirring tank, which solves the technical problem in the prior art that the viscosity of adhesive, the size of bubbles and the stability of bubbles will affect the efficiency of centrifugal degassing.

[0006] The present invention provides a chemical stirring tank, comprising a base and a stirring tank on which the top of the base is fixedly installed and which is composed of a lower tank body and an upper tank body, wherein a driving motor is fixedly installed on the top of the upper tank body, and a stirring preparation degassing unit, a pressing type intermittent dispersing feeding unit and a multi-step collision centrifugal degassing unit are arranged in the stirring tank, wherein the pressing type intermittent dispersing feeding unit comprises an intermittent dispersing feeding component, a control component, a driving component one and a pressing dispersing component, and the multi-step collision centrifugal degassing unit comprises a stepped centrifugal component and a driving component two, and an exhaust unit is arranged on the right side of the stirring tank.

[0007] The intermittent dispersion feeding component includes a fixed filter screen fixedly installed on the inner wall of the lower tank body and a rotating filter screen rotatably installed on the inner wall of the lower tank body. The stepped centrifugal component includes a mounting ring fixedly installed on the inner wall of the lower tank body and a conical centrifugal bucket rotatably installed on the inner wall of the mounting ring and located below the rotating filter screen. A plurality of collision steps are sequentially arranged in the conical centrifugal bucket from top to bottom.

[0008] The stirring preparation and degassing unit stirs the adhesive in the upper tank body, and the exhaust unit extracts the bubbles generated during stirring. After preparation, the rotating filter rotates until it overlaps with the fixed filter, and the pressing and dispersing component presses the adhesive downward to disperse the adhesive through the filter holes into the conical centrifugal bucket for secondary degassing by rotation collision.

[0009] Furthermore, the output shaft of the driving motor slides through the inner wall of the top of the upper tank body, and the stirring and degassing unit includes a mounting sleeve fixedly mounted on the outside of the output shaft of the driving motor and a plurality of stirring blades fixedly mounted on the outside of the mounting sleeve.

[0010] Furthermore, the vacuum unit includes several pipe racks fixedly installed on the right side of the mixing tank, and a U-shaped tube is installed between the several pipe racks. The two ends of the U-shaped tube are respectively connected to the upper tank body and the lower tank body, and a vacuum pipe connected to an external vacuum pump is fixedly installed on the right side of the U-shaped tube.

[0011] Furthermore, the control component includes a plurality of mounting rods fixedly mounted on the inner wall of the lower tank body and located above the conical centrifugal bucket, and a mounting cover fixedly mounted between the plurality of mounting rods, a mounting plate fixedly mounted on the outside of the mounting cover, a rotating shaft 1 is rotatably mounted on the top of the mounting plate, an eccentric plate is fixedly mounted on the top of the rotating shaft 1, a plurality of U-shaped plates are fixedly mounted on the bottom of the rotating filter screen, and an eccentric rod matching the U-shaped groove on the U-shaped plate is fixedly mounted on the top of the eccentric plate.

[0012] Furthermore, the driving component 1 includes a rotating shaft 2 rotatably mounted on the mounting cover and passing through the mounting cover, a fixed sleeve at one end of the rotating shaft 2 located inside the mounting cover is provided with a worm gear, a small motor is fixedly mounted on the mounting cover, a worm meshing with the worm gear is fixedly mounted on the bottom end of the output shaft of the small motor, a fixed sleeve at one end of the rotating shaft 2 located outside the mounting cover is provided with a driving bevel gear, a fixed sleeve on the outer side of the rotating shaft 1 is provided with a driven bevel gear meshing with the driving bevel gear, and a sliding sleeve is fixedly mounted on the mounting plate and is provided on the outer side of the rotating shaft 2.

[0013] Furthermore, the material pressing and dispersing assembly includes a cylinder fixedly mounted on the top of the upper tank body, the output end of the cylinder slides through the top inner wall of the upper tank body, and a material pressing plate is fixedly mounted on the output end of the cylinder. After the adhesive stirring preparation is completed and the rotating filter screen rotates to overlap with the fixed filter screen, the output end of the cylinder pushes the material pressing plate down to press the adhesive to achieve the effect of material pressing and dispersing. After the output end of the cylinder is fully extended, the material pressing plate is still located above the stirring blade.

[0014] Furthermore, the driving component 2 includes a plurality of shaft frames fixedly mounted on the left side of the mixing tank and a rotating shaft 3 rotatably mounted between the plurality of shaft frames. An upper driving pulley is provided on the outer fixed sleeve of the output shaft of the driving motor, and an upper driven pulley is provided on the top fixed sleeve of the rotating shaft 3. An upper belt is connected for transmission between the upper driving pulley and the upper driven pulley.

[0015] Furthermore, a lower driving pulley is provided on the outer fixed sleeve of the rotating shaft, a belt groove is provided on the outer side of the conical centrifugal bucket, and a lower belt is connected between the lower driving pulley and the belt groove for common transmission.

[0016] Furthermore, a feed port is provided at the top of the upper tank body, a feed pipe is provided in the feed port, and the feed pipe extends to the bottom of the upper tank body and is located above the stirring blade.

[0017] Furthermore, a discharge pipe which is fixedly installed at the bottom of the conical centrifugal bucket and passes through the lower tank body is provided, and a discharge valve is provided on the discharge pipe.

[0018] The beneficial effects of the present invention are: 1. Through the multi-step collision design, the adhesive continuously collides with multiple collision steps from top to bottom under the continuous action of centrifugal force. The continuous collision enables the large and small bubbles in the adhesive to burst quickly, thereby achieving the effect of continuous collision degassing, and even small bubbles or bubbles that are not easy to burst due to the presence of surfactants can burst in the continuous collision, thereby avoiding the influence of the bubble size, viscosity and bubble stability in the adhesive on the degassing effect, thereby greatly improving the degassing effect.

[0019] 2. The intermittent pressing and dispersing feeding unit is used to achieve the effect of intermittent pressing and dispersing feeding. The adhesive after extrusion and dispersion forms fine streams, so that more bubbles are exposed on the adhesive surface during centrifugal dispersion and degassing, which are more susceptible to collision and thus more likely to break, thereby improving the degassing effect.

[0020] 3. By performing preliminary degassing during the adhesive stirring preparation process, and then performing secondary multi-step collision centrifugal degassing after the preparation is completed, the bubbles in the adhesive can be eliminated to the greatest extent, thereby improving the degassing effect and speed.

DETAILED DESCRIPTION

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In this embodiment, a chemical stirring tank is proposed, including a base 10 and a stirring tank 1 fixedly installed on the top of the base 10 and consisting of a lower tank body 101 and an upper tank body 102, a driving motor 2 is fixedly installed on the top of the upper tank body 102, and a stirring preparation degassing unit 3, a pressing type intermittent dispersion feeding unit 4 and a multi-step collision centrifugal degassing unit 5 are arranged in the stirring tank 1, the pressing type intermittent dispersion feeding unit 4 includes an intermittent dispersion feeding component 401, a control component 402, a driving component 1 403 for driving the control component 402 to drive the intermittent dispersion feeding component 401 to move, and a pressing dispersion component 404, the multi-step collision centrifugal degassing unit 5 includes a stepped centrifugal component 501 and a driving component 2 502 for driving the stepped centrifugal component 501 to rotate at a high speed, and an exhaust unit 9 is arranged on the right side of the stirring tank 1.

[0032] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 A feed port 6 is provided at the top of the upper tank body 102 , and a feed pipe is provided in the feed port 6 .

[0033] See also Figure 1 , Figure 2 and Figure 3 The exhaust unit 9 includes a plurality of pipe racks 901 fixedly installed on the right side of the stirring tank 1, and a U-shaped tube 902 is installed between the plurality of pipe racks 901. The two ends of the U-shaped tube 902 are respectively connected to the upper tank body 102 and the lower tank body 101, and an exhaust pipe 903 connected to an external exhaust pump is fixedly installed on the right side of the U-shaped tube 902.

[0034] See also Figure 2 and Figure 5 The output shaft of the driving motor 2 slides through the inner wall of the top of the upper tank body 102. The stirring and degassing unit 3 includes a mounting sleeve 301 fixedly mounted on the outside of the output shaft of the driving motor 2 and a plurality of stirring blades 302 fixedly mounted on the outside of the mounting sleeve 301. The feed pipe extends to the bottom of the upper tank body 102 and is located above the stirring blades 302.

[0035] When in use, the stirring tank 1 is first preheated by an external heating component, and a constant temperature is maintained in the stirring tank 1 during the process of stirring and preparing the adhesive. Then, the raw materials required for stirring and preparing the adhesive are introduced into the bottom of the upper tank body 102 through the feeding pipe and fall on the top of the intermittent dispersion feeding component 401. Since the feeding pipe directly extends to the bottom of the upper tank body 102, the raw materials flow upward from the bottom and contact the air in the tank during feeding. Since the raw materials have a large velocity gradient when flowing upward from the bottom, that is, the flow velocities at different positions are significantly different, shear force is generated inside the raw materials, making the movement of the raw materials irregular, causing turbulence, The formation and movement of turbulence will further intensify the irregular movement of the raw materials, thereby enhancing the mixing effect inside the raw materials, and the air is evenly dispersed in the raw materials, which helps to reduce the aggregation of bubbles during the stirring preparation process. Next, the drive motor 2 is started, and the output shaft of the drive motor 2 rotates to drive the stirring blade 302 to rotate at high speed to stir the raw materials to mix and prepare the adhesive. During the adhesive stirring preparation process, an external vacuum pump extracts the air inside the stirring tank 1 through the vacuum pipe 903 to allow the bubbles generated during stirring to escape, thereby eliminating the bubbles generated during the mixing preparation process, thereby realizing the preparation and preliminary degassing operation of integrated preparation and degassing.

[0036] See also Figure 2 , Figure 3 , Figure 4 and Figure 7 The intermittent dispersion feeding component 401 includes a fixed filter screen 4011 fixedly mounted on the inner wall of the lower tank body 101 and a rotating filter screen 4012 rotatably mounted on the inner wall of the lower tank body 101. Initially, the filter holes on the fixed filter screen 4011 and the rotating filter screen 4012 alternate with each other. After the adhesive is stirred and prepared, the rotating filter screen 4012 is rotated to overlap with the fixed filter screen 4011 to perform dispersion feeding.

[0037] See also Figure 3 , Figure 4 , Figure 7 and Figure 8 The control component 402 includes a plurality of mounting rods 4021 fixedly mounted on the inner wall of the lower tank body 101 and a mounting cover 4022 fixedly mounted between the plurality of mounting rods 4021, a mounting plate 4023 is fixedly mounted on the outer side of the mounting cover 4022, a rotating shaft 4024 is rotatably mounted on the top of the mounting plate 4023, an eccentric plate 4025 is fixedly mounted on the top of the rotating shaft 4024, a plurality of U-shaped plates 4027 are fixedly mounted on the bottom of the rotating filter screen 4012, and an eccentric rod 4026 matching the U-shaped groove on the U-shaped plate 4027 is fixedly mounted on the top of the eccentric plate 4025.

[0038] See also Figure 3 , Figure 4 , Figure 7 and Figure 8 The driving component 1 403 includes a rotating shaft 2 4031 rotatably mounted on the mounting cover 4022 and passing through the mounting cover 4022, a worm gear 4032 is fixedly sleeved at one end of the rotating shaft 2 4031 located inside the mounting cover 4022, a small motor 4037 is fixedly mounted on the mounting cover 4022, a worm 4033 meshing with the worm gear 4032 is fixedly mounted at the bottom end of the output shaft of the small motor 4037, a driving bevel gear 4034 is fixedly sleeved at one end of the rotating shaft 2 4031 located outside the mounting cover 4022, a driven bevel gear 4035 meshing with the driving bevel gear 4034 is fixedly sleeved on the outer side of the rotating shaft 1 4024, and a sleeve 4036 slidingly sleeved on the outer side of the rotating shaft 2 4031 is fixedly mounted on the mounting plate 4023.

[0039] During specific use, after preparation and preliminary degassing are completed, the small motor 4037 is started to drive the worm 4033 to drive the worm wheel 4032 to rotate, thereby driving the rotating shaft 2 4031 to rotate at a reduced speed, and then driving the driven bevel gear 4035 to rotate through the driving bevel gear 4034, driving the rotating shaft 1 4024 to rotate slowly and uniformly, thereby driving the eccentric rod 4026 to rotate through the eccentric plate 4025 and gradually rotate to the U-shaped groove on the U-shaped plate 4027 closest to the rotation direction of the eccentric rod 4026, and then the U-shaped groove is moved to drive the U-shaped plate 4027 to move, thereby driving the rotating filter screen 4012 to rotate gradually. When the filter holes on the rotating filter screen 4012 gradually rotate to below the filter holes of the fixed filter screen 4011, the prepared adhesive is pressed down by the pressing and dispersing component 404, so that the adhesive is quickly squeezed out of the filter holes under pressure and enters the stepped centrifugal component 501 for centrifugal collision degassing.

[0040] When the filter holes on the rotating filter 4012 gradually detach from the filter holes under the fixed filter 4011, the portion of the rotating filter 4012 without filter holes fits with the filter holes of the fixed filter 4011, thereby blocking the filter holes of the fixed filter 4011, and at the same time the material pressing and dispersing assembly 404 stops, thereby suspending the feeding of the adhesive, and when the filter holes on the rotating filter 4012 rotate again to below the filter holes of the fixed filter 4011, the adhesive is pressed down by the material pressing and dispersing assembly 404 to repeat the feeding operation, and as the rotating filter 4012 continues to rotate slowly, the adhesive is intermittently pressed down and squeezed into the stepped centrifugal assembly 501 for centrifugal collision degassing.

[0041] See also Figure 1 , Figure 2 and Figure 7The material pressing and dispersing assembly 404 includes a cylinder 4041 fixedly mounted on the top of the upper tank body 102, the output end of the cylinder 4041 slides through the top inner wall of the upper tank body 102, and a material pressing plate 4042 is fixedly mounted on the output end of the cylinder 4041. After the adhesive stirring preparation is completed and the rotating filter screen 4012 rotates to overlap with the fixed filter screen 4011, the output end of the cylinder 4041 pushes the material pressing plate 4042 to press the adhesive down to achieve the effect of material pressing and dispersing. After the output end of the cylinder 4041 is fully extended, the material pressing plate 4042 is still located above the stirring blade 302.

[0042] During specific use, when the filter holes on the rotating filter 4012 gradually rotate to below the filter holes of the fixed filter 4011, the cylinder 4041 is started so that the output end of the cylinder 4041 pushes the pressing plate 4042 to move downward, thereby squeezing and dispersing the prepared adhesive downward, allowing the dispersed adhesive to pass through the filter holes on the fixed filter 4011 and the rotating filter 4012 and enter the stepped centrifugal assembly 501 for centrifugal collision degassing, thereby achieving the effect of intermittent pressing, dispersing and feeding. After squeezing and dispersing, the adhesive forms fine streams, so that more bubbles are exposed on the adhesive surface during centrifugal dispersion and degassing, making them more susceptible to collision and thus more likely to break, thereby improving the degassing effect.

[0043] See also Figure 2 , Figure 5 and Figure 6 The stepped centrifugal assembly 501 includes a mounting ring 5011 fixedly mounted on the inner wall of the lower tank body 101 and a conical centrifugal bucket 5012 rotatably mounted on the inner wall of the mounting ring 5011 and located below the rotating filter screen 4012. A plurality of collision steps 5013 are sequentially provided in the conical centrifugal bucket 5012 from top to bottom, and the top surface of the collision step 5013 is inclined toward the center of the conical centrifugal bucket 5012. A discharge pipe 7 that passes through the lower tank body 101 is fixedly mounted at the bottom of the conical centrifugal bucket 5012, and a discharge valve 8 is provided on the discharge pipe 7. The mounting rod 4021 is located above the conical centrifugal bucket 5012.

[0044] See also Figure 1 , Figure 2 and Figure 5 The driving component 2 502 includes a plurality of shaft frames 5021 fixedly mounted on the left side of the mixing tank 1 and a rotating shaft 3 5022 rotatably mounted between the plurality of shaft frames 5021. An upper driving pulley 5023 is provided on the outer fixed sleeve of the output shaft of the driving motor 2. An upper driven pulley 5024 is provided on the top fixed sleeve of the rotating shaft 3 5022. An upper belt 5025 is connected to the upper driving pulley 5023 and the upper driven pulley 5024 for transmission.

[0045] See also Figure 1 , Figure 2 and Figure 5 A lower driving pulley 5026 is fixedly mounted on the outer side of the rotating shaft 5022, a belt groove is provided on the outer side of the conical centrifugal bucket 5012, and a lower belt 5027 is connected to the lower driving pulley 5026 and the belt groove for common transmission.

[0046] When in use, the output shaft of the driving motor 2 rotates while also driving the upper driving pulley 5023 to rotate. The upper driving pulley 5023 drives the upper driven pulley 5024 to rotate through the upper belt 5025, thereby driving the rotating shaft 3 5022 to rotate, so that the lower driving pulley 5026 drives the conical centrifugal bucket 5012 to rotate at high speed through the lower belt 5027. When the pressing plate 4042 squeezes and disperses the prepared adhesive downward, so that the dispersed adhesive passes through the filter holes on the fixed filter screen 4011 and the rotating filter screen 4012 and enters the conical centrifugal bucket 5012, due to the high-speed rotation of the conical centrifugal bucket 5012, the adhesive is subjected to the centrifugal force to flow radially, thereby quickly moving to the side close to the collision step 5013. And it collides with the next collision step 5013, so that the bubbles in the adhesive are burst by the impact force, and the adhesive will partially rebound after the collision to form a new flow path. The adhesive after rebounding continues to be affected by the centrifugal force. At the same time, due to the effect of gravity, the adhesive will gradually move downward and collide with the next collision step 5013 again. Under the continuous action of centrifugal force, the adhesive will continuously collide with multiple collision steps 5013 from top to bottom. The continuous collision makes the large and small bubbles in the adhesive burst quickly, thereby achieving the effect of continuous collision degassing and finally being discharged through the discharge pipe 7 at the bottom of the conical centrifugal bucket 5012, realizing continuous discharging, and finally achieving the effect of multi-step collision centrifugal degassing.

[0047] While the multi-step collision centrifugal degassing is being performed, the ruptured bubbles will escape from the adhesive surface to form gas, and an external vacuum pump will extract the air inside the lower tank body 101 through the vacuum pipe 903 and the U-shaped tube 902.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
