Description

Technical Field

[0001] The invention relates to the technical field of sodium carboxymethyl cellulose production, in particular to a batching tank for sodium carboxymethyl cellulose production. Background Art

[0002] Sodium carboxymethyl cellulose is an organic substance, a carboxymethyl derivative of cellulose, and the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound prepared by the reaction of natural cellulose with caustic soda and monochloroacetic acid. Sodium carboxymethyl cellulose is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily dispersed in water to form a transparent colloidal solution.

[0003] During the production of sodium carboxymethyl cellulose, especially during its alkalization and etherification reaction, sodium hydroxide and sodium chloroacetate need to be gradually added to react with cellulose, and in this process, sufficient stirring is required to allow the cellulose to fully mix and react with the two. However, the existing batching tank has a simple structure and often only uses stirring blades to mix and stir various ingredients, which has low stirring efficiency and poor effect. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a batching tank for the production of sodium carboxymethyl cellulose, which solves the technical problems of low stirring efficiency, poor mixing effect and influence on reaction rate in the prior art, and achieves the purpose of improving mixing efficiency.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a batching tank for sodium carboxymethyl cellulose production, comprising a supporting foot installed at the bottom of the batching tank, a mixing mechanism for mixing and stirring various ingredients is arranged in the batching tank, and a jet feeding mechanism for quantitatively adding ingredients is arranged on the batching tank.

[0006] The mixing mechanism includes a mixing shaft rotatably connected to a rotating hole opened on a mixing tank, a plurality of groups of connecting rods are vertically and equidistantly installed on the mixing shaft, a hinge seat is installed at one end of the connecting rod away from the mixing shaft, a suspension rod is hinged in the hinge seat, a ball seat is installed at the bottom of the suspension rod, and stirring rods are symmetrically installed at both ends of the ball seat, a driving motor for driving the mixing shaft to rotate is installed on the mixing tank, a stirring component for disorderly mixing the liquid flow is arranged on the ball seat, and a moving component for driving the mixing mechanism to move the mixing material up and down is arranged on the mixing shaft.

[0007] A further improvement is that the stirring assembly includes a ball ring installed at the bottom of the suspension rod, and the ball seat is rotatably connected to the inside of the ball ring. The stirring rod is sleeved with a sleeve, and the sleeve is equipped with stirring plates in a ring array.

[0008] A further improvement is that the stirring plate is a semicircular structure, and cut spoiler holes are evenly opened through the stirring plate.

[0009] A further improvement is that the moving component includes a slide groove opened on the mixing shaft, and a tension spring is installed on the top wall of the slide groove, a guide slider is installed on the bottom of the tension spring, and the connecting rod is obliquely installed on the outer arc surface of the guide slider.

[0010] A further improvement is that an electric heating plate is installed in the installation cavity opened in the inner wall of the batching tank, and a temperature sensor for real-time monitoring of the internal temperature of the batching tank is installed on the top wall of the batching tank.

[0011] A further improvement is that the jet feeding mechanism includes a water pump installed on the top of the batching tank, and the water pump's water suction interface is equipped with a water suction pipe extending from the bottom into the interior of the batching tank, the water outlet interface of the water pump is equipped with a jet tube, and the double-headed water outlet end of the jet tube extends into the interior of the batching tank and is equipped with a Venturi tube, the jet tube is equipped with a connecting pipe connected to it, and a feeding box is installed on the top of the connecting pipe, and a flow valve is installed in the middle.

[0012] A further improvement is that the feeding box is of cylindrical structure, and a rotating shaft is rotatably connected in a rotating groove opened in the middle of the feeding box, and a plurality of mixing blades are equidistantly installed along the outer surface of the rotating shaft.

[0013] A further improvement is that an observation window and a controller are installed on the batching tank, and the mixing mechanism and the jet feeding mechanism are both electrically connected to the controller.

[0014] By means of the above technical scheme, the present invention provides a batching tank for the production of sodium carboxymethyl cellulose, which has at least the following beneficial effects: 1. In the process of the stirring rod rotating and colliding with the liquid flow, the liquid flow drives the stirring rod and the suspension rod thereon to swing left and right in the hinge seat, so that the stirring rod swings left and right to rotate and mix the raw materials, thereby improving the mixing and stirring effect.

[0015] 2. When the stirring rod of the present invention rotates to stir, the stirring plate thereon beats the liquid flow and drives the sleeve to rotate on the stirring rod during the process, and the reaction force during the stirring process drives the ball seat to rotate disorderly inside the ball ring, thereby driving the stirring plate to flip disorderly, further improving the stirring effect.

[0016] 3. The present invention causes the stirring plate to perform disordered flipping in the liquid flow, so the reaction force generated, assisted by the pulling elastic force of the tension spring itself, can drive the guide slider to bounce up and down in the slide groove, thereby driving the stirring plate to move up and down to mix the materials, further improving the mixing effect.

[0017] 4. When the present invention uses a water pump to pump the liquid into the jet tube and then flows into the venturi tube, the flow valve on the connecting pipe is started to discharge the chemical agent into the jet tube in a quantitative manner. When the chemical agent flows into the venturi tube, a high-speed jet fluid is formed and the liquid raw material and the chemical agent are mixed, which not only realizes the addition of materials, but also mixes the liquid and the chemical agent, thereby improving the reaction rate.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] Based on the existing existing technology with low stirring efficiency, poor mixing effect, and the problem of affecting the reaction rate, this embodiment provides a batching tank for the production of sodium carboxymethyl cellulose, please refer to Figure 1-Figure 5 The batching tank for sodium carboxymethyl cellulose production includes a supporting foot 2 installed at the bottom of the batching tank 1, a mixing mechanism 3 for mixing and stirring various ingredients is arranged in the batching tank 1, and a jet feeding mechanism 4 for quantitatively feeding ingredients is arranged on the batching tank 1. Various ingredients are added into the batching tank 1 through the jet feeding mechanism 4 to react with cellulose, and the mixing mechanism 3 is used to mix and stir various ingredients in a disordered manner, thereby improving the efficiency of the mixing reaction.

[0024] The prior art has low stirring efficiency and poor mixing effect, which affects the reaction rate. Therefore, the device is provided with a mixing mechanism 3, which includes a mixing shaft 31 rotatably connected to a rotating hole opened on the batching tank 1, and a plurality of connecting rods 32 are vertically and equidistantly installed on the mixing shaft 31, and a hinge seat 33 is installed at one end of the connecting rod 32 away from the mixing shaft 31, and a hanging rod 34 is hinged in the hinge seat 33, a ball seat 35 is installed at the bottom of the hanging rod 34, and stirring rods 36 are symmetrically installed at both ends of the ball seat 35, and a driving motor 37 for driving the mixing shaft 31 to rotate is installed on the batching tank 1 A stirring component 38 for disorderly stirring the liquid flow is arranged on the ball seat 35, and a moving component 39 for driving the mixing mechanism 3 to move up and down to mix the materials is arranged on the mixing shaft 31. The driving motor 37 is started to drive the mixing shaft 31 to rotate, thereby driving the stirring rod 36 on the hinge seat 33 at the end of the connecting rod 32 on the mixing shaft 31 to rotate to mix and stir the liquid flow in the batching tank 1, and in the process of collision and stirring between the stirring rod 36 and the liquid flow, the liquid flow drives the stirring rod 36 to shake, thereby driving the suspension rod 34 to swing left and right in the hinge seat 33, thereby improving the mixing and stirring effect.

[0025] In order to further improve the mixing effect, the device is also provided with a stirring assembly 38, which includes a ball ring 381 installed at the bottom of the suspension rod 34, and the ball seat 35 is rotatably connected to the inside of the ball ring 381, a sleeve 382 is sleeved on the stirring rod 36, and a stirring plate 383 is installed in a ring array on the sleeve 382. As the stirring rod 36 stirs the liquid flow, the stirring plate 383 on the stirring rod 36 beats the liquid flow and drives the sleeve 382 to rotate on the stirring rod 36. The reaction force during the stirring process drives the ball seat 35 to rotate disorderly inside the ball ring 381, and then drives the stirring plate 383 to flip disorderly, thereby further improving the stirring effect.

[0026] In order to prevent the edge of the stirring plate 383 from hitting the suspension rod 34 or the mixing shaft 31 when the stirring plate 383 stirs the mixture disorderly, the device sets the stirring plate 383 to a semicircular structure, and cutting spoiler holes are evenly opened on the stirring plate 383. As the stirring plate 383 stirs the mixture disorderly, the cutting spoiler holes opened on it further cut the liquid flow and mix the mixture, thereby improving the mixing effect. The reaction force generated by the liquid flow when flowing through the cutting spoiler holes further drives the stirring plate 383 to stir and mix the mixture.

[0027] Since the temperature requirements for liquid raw materials are different in different reaction processes, the device is equipped with an electric heating plate 310 in the installation cavity opened on the inner wall of the batching tank 1, and a temperature sensor 311 for real-time monitoring of the internal temperature of the batching tank 1 is installed on the top wall of the batching tank 1. The temperature sensor 311 is used to monitor the reaction temperature of the liquid flow in the batching tank 1 in real time, and the electric heating plate 310 is used to heat the liquid flow and maintain a constant temperature to facilitate the reaction.

[0028] Since different chemical agents need to be added during the reaction process, the device is also provided with a jet feeding mechanism 4, which includes a water pump 41 installed on the top of the batching tank 1, and the water pump interface of the water pump 41 is installed with a water pump 42 extending from the bottom into the interior of the batching tank 1, and the water outlet interface of the water pump 41 is installed with a jet pipe 43, and the double-headed water outlet end of the jet pipe 43 extends into the interior of the batching tank 1, and is installed with a venturi tube 44, and a connecting pipe 45 connected to the jet pipe 43 is installed on the jet pipe 43, and a connecting pipe 45 is installed on the top of the connecting pipe 45. The feeding box 46 has a flow valve 47 installed in the middle. When adding chemicals, the water pump 41 is started to pump the liquid in the batching tank 1 into the jet tube 43 through the pumping pipe 42. At this time, the flow valve 47 on the connecting pipe 45 is started to discharge the chemical agent in the feeding box 46 into the jet tube 43 through the connecting pipe 45 in a quantitative manner. When the chemical agent flows into the venturi tube 44, a high-speed jet fluid is formed to mix the liquid raw material and the chemical agent, which not only realizes the addition of materials, but also mixes the liquid and the chemical agent, thereby increasing the reaction rate.

[0029] The feeding box 46 is a cylindrical structure, and a rotating shaft 48 is rotatably connected in a rotating groove opened in the middle of the feeding box 46, and a plurality of mixing blades 49 are equidistantly installed along the outer surface of the rotating shaft 48. When the chemical agent in the feeding box 46 flows into the jet tube 43 through the connecting pipe 45, the suction force generated by the high-speed flowing liquid drives the mixing blades 49 on the rotating shaft 48 in the feeding box 46 to rotate, and the sodium hydroxide or sodium chloroacetate melt in the feeding box 46 is stirred and dissolved, making it more convenient to react and mix with the liquid raw material.

[0030] An observation window 51 and a controller 52 are installed on the batching tank 1. The mixing mechanism 3 and the jet feeding mechanism 4 are electrically connected to the controller 52. The reaction progress of the raw materials in the batching tank 1 can be observed in real time through the observation window 51, and the normal operation of the device can be controlled by the controller 52.

[0031] Example 2

[0032] On the basis of Example 1, Figure 1-Figure 5 As shown, in order to further improve the mixing effect, the device is further provided with a moving component 39, which includes a slide groove 391 opened on the mixing shaft 31, and a tension spring 392 is installed on the top wall of the slide groove 391, and a guide slider 393 is installed on the bottom of the tension spring 392, and the connecting rod 32 is obliquely installed on the outer arc surface of the guide slider 393. The centrifugal force generated during the rotation of the mixing shaft 31, assisted by the pulling force generated by the flipping and stirring of the stirring plate 383, drives the guide slider 393 to slide downward inside the slide groove 391 and pull the tension spring 392. Since the stirring plate 383 flips disorderly in the liquid flow, the reaction force generated, assisted by the pulling elastic force of the tension spring 392 itself, can drive the guide slider 393 to bounce up and down in the slide groove 391, thereby driving the stirring plate 383 to move up and down to mix, thereby further improving the mixing effect.
