Description

Technical Field

[0001] The invention relates to the technical field of physical or chemical reaction containers, and in particular to a carboxylic acid water reducer reaction kettle. Background Art

[0002] Polycarboxylate water reducer is a high-performance concrete admixture, which is widely used in various construction projects, including highways, bridges, tunnels, housing construction projects, water conservancy projects and port projects. In the synthesis stage of polycarboxylate water reducer, a reactor is usually required as a reaction container.

[0003] The Chinese patent document with the authorization announcement number CN209205295U discloses a polycarboxylate water-reducing agent reactor, including a reactor body, a power device and an agitator, wherein the power device is arranged at the top of the reactor body, the agitator is arranged at the inner side of the reactor body and connected to the power device, and the power device is used to drive the agitator to rotate. A feed port and a plurality of solution feed ports are arranged at the top of the reactor body, the feed port is used to introduce solid materials into the reactor body, and the solution feed port is used to introduce liquid raw materials into the reactor body.

[0004] When in use, liquid raw materials can be introduced into the kettle through the solution feeding port first, and then the power device drives the stirrer to rotate, and the stirrer stirs these liquid raw materials. While stirring, the operator can continue to introduce solid materials through the feeding port. Under the stirring of the stirrer, the solid materials and liquid raw materials are gradually mixed together and begin to react. This operation deepens the reaction degree of the solid materials and liquid raw materials.

[0005] However, in the specific implementation, the above-mentioned polycarboxylate water-reducing agent reactor still has shortcomings: under different conditions, the speed of the agitator may be faster or slower. When the agitator rotates faster, the speed of adding solid materials should also be accelerated to avoid adding less and not keeping up with the reaction of the liquid raw materials, thereby affecting the entire reaction process. When the agitator rotates slowly, the speed of adding solid materials should also be slowed down to avoid adding too much and not being able to react in time. However, it is difficult for the operator to control the feeding speed by manually or through tools to pass the material to the feeding port, resulting in excessive or insufficient feeding, affecting the reaction. Summary of the invention

[0006] The invention provides a carboxylic acid water reducer reaction kettle, aiming to solve the problem in the related art that the feeding speed and the stirring speed are difficult to match each other, thus affecting the reaction.

[0007] The carboxylic acid water-reducing agent reactor of the present invention comprises a reactor body, a stirring paddle, an intermediate shaft, a stirring shaft and a sliding member, wherein the top of the reactor body is provided with a feed inlet, and the stirring paddle is placed in the reactor body; the intermediate shaft is arranged in the reactor body and can rotate, and a first conical plate is coaxially connected to the intermediate shaft, and upper feeding holes are evenly distributed on the first conical plate; the stirring shaft is rotatably arranged below the intermediate shaft, and the stirring paddle is connected to the stirring shaft; a second conical plate is coaxially connected to the stirring shaft, and lower feeding holes are evenly distributed on the second conical plate, and the first conical plate and the second conical plate are fitted up and down, and in an initial state, the upper feeding holes and the lower feeding holes partially overlap; the sliding member is elastically slidably connected to the stirring shaft along the radial direction of the stirring shaft, a limiting groove is provided in the intermediate shaft, one end of the sliding member is slidably matched in the limiting groove, and an inclined surface is provided at the end of the sliding member located in the limiting groove, and when the intermediate shaft drives the stirring shaft to rotate through the sliding member, under the action of centrifugal force, the sliding member can slide to the outside of the limiting groove and drive the inclined surface to gradually move to the notch of the limiting groove.

[0008] When the inclined plane moves to the notch of the limiting groove, the rotating intermediate shaft will press the notch edge of the limiting groove against the inclined plane, and the sliding part is equivalent to being deflected back a little along the circumference of the intermediate shaft. The sliding part pushes the stirring shaft and the second conical plate to deflect back a little, and the overlapping part of the lower feeding hole and the upper feeding hole increases. From the above, it can be seen that the faster the intermediate shaft, the stirring shaft and the stirring paddle rotate, the more overlapping parts of the lower feeding hole and the upper feeding hole will be. At this time, the passing speed of the solid material will be accelerated. Conversely, when the rotation of the stirring shaft and the stirring paddle slows down, the feeding speed of the solid material also slows down. Thereby, the feeding speed of the solid material can change with the change of the stirring speed, which not only ensures the entire reaction time and reaction process, but also ensures that the amount of solid material added can just react fully with the liquid raw material.

[0009] Preferably, the carboxylic acid water-reducing agent reactor further comprises a driving shaft, a sleeve and a material guide pipe, wherein the driving shaft is arranged in the reactor body, and the top end is rotatably connected to the reactor body, and the bottom end is connected to the intermediate shaft; the sleeve is slidably sleeved on the driving shaft and connected to the driving shaft through an elastic member; a moving block is elastically slidably connected to the driving shaft along its radial direction, and a wedge-shaped structure is arranged between the moving block and the sleeve, so that when the moving block slides outward, the sleeve can be squeezed downward through the wedge-shaped structure; the material guide pipe is L-shaped, one end of which is rotatably fitted in the feed port, and the other end is located above the first conical plate; a connecting frame is arranged between the material guide pipe and the sleeve, one end of the connecting frame is rotatably connected to the sleeve, and the other end is spirally driven with the material guide pipe.

[0010] Preferably, the wedge-shaped structure comprises a wedge-shaped block arranged on the collar and a wedge-shaped portion formed on the moving block, and the wedge-shaped block and the wedge-shaped portion fit each other.

[0011] When the drive shaft rotates, centrifugal force is generated on the moving block, and the moving block slides toward the outside of the drive shaft under the action of centrifugal force. The wedge-shaped portion squeezes the wedge-shaped block and forces the collar to slide downward through the wedge-shaped block. The collar drives the connecting frame to move downward, and the connecting frame drives the guide tube to rotate, so that the discharge part of the guide tube is closer to the center of the first conical plate. In this way, the falling solid material can be closer to the center of the first conical plate to achieve resistance to centrifugal force. In other words, the falling solid material can be evenly spread on the first conical plate under the action of centrifugal force, ensuring the uniformity of feeding.

[0012] Preferably, the material guide pipe is passed through the connecting frame, and a spiral groove is provided on the outer wall of the material guide pipe, and a spiral push rod matched in the spiral groove is provided on the connecting frame.

[0013] When the connecting frame moves downward, the material guide pipe is driven to rotate through the cooperation of the spiral push rod and the spiral groove.

[0014] Preferably, the intermediate shaft and the driving shaft are elastically slidably connected along the axial direction of the driving shaft; a moving gear ring is provided on the outer periphery of the first conical plate, and a stationary gear ring located above the moving gear ring is fixed on the inner wall of the kettle body, and the teeth on the stationary gear ring and the moving gear ring are oriented oppositely, and when the first conical plate drives the moving gear ring to rotate, the teeth on the moving gear ring can contact with the teeth on the stationary gear ring, and under the action of the extrusion force, the moving gear ring slides downward.

[0015] Preferably, a column cavity is provided in the driving shaft, a limiting cylinder coaxial with the driving shaft is fixed in the column cavity, a limiting shaft is fixed at the top end of the intermediate shaft, and the limiting shaft is slidably fitted in the limiting cylinder; a connecting spring is also provided in the column cavity and is sleeved on the outer peripheral side of the limiting cylinder, and both ends of the connecting spring are respectively fixedly connected to the driving shaft and the intermediate shaft.

[0016] When the first conical plate rotates, it drives the moving gear ring to squeeze and contact with the stationary gear ring. The moving gear ring slides downward to avoid the stationary gear ring, thereby causing the connecting spring to lengthen. When the teeth on the moving gear ring pass over the teeth on the stationary gear ring, the connecting spring pulls the moving gear ring to reset. As a result, the moving gear ring will continuously slide up and down during rotation, thereby causing the first conical plate to vibrate. The vibrating first conical plate is more conducive to the passage of solid materials and reduces blockage.

[0017] Preferably, there are a plurality of stirring paddles which are spaced apart along the circumference of the stirring shaft.

[0018] Multiple stirring paddles stir simultaneously, which speeds up the mixing rate of solid materials and liquid raw materials.

[0019] Preferably, a motor is provided at the top of the kettle body, and the motor is connected to the driving shaft so as to drive the driving shaft to rotate.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0021] The present invention realizes the linkage between the intermediate shaft and the stirring shaft through the setting of the sliding part, and enables the sliding part to move outward under the action of centrifugal force, so that the inclined surface is at the edge of the notch of the limiting groove, thereby changing the contact position of the sliding part and the intermediate shaft, realizing the return deflection of the sliding part, and then making the second conical plate return deflection, expanding the overlapping part of the lower feeding hole and the upper feeding hole. When the stirring shaft rotates faster, the above-mentioned overlapping part is larger, and when the stirring shaft rotates slower, the above-mentioned overlapping part is smaller. In this way, the feeding speed is regulated, so that the feeding speed and the stirring speed can be matched, which not only ensures the entire reaction time and reaction process, but also ensures that the amount of solid material added is just enough to fully react with the liquid raw material.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] Combine the following Figures 1 to 8 The carboxylic acid water-reducing agent reactor of the present invention is described.

[0039] like Figures 1 to 5 As shown, the carboxylic acid water-reducing agent reactor of the present invention comprises a reactor body 1 , a driving shaft 2 , an intermediate shaft 3 , a stirring shaft 4 , a stirring paddle 41 and a sliding member 42 .

[0040] The top of the kettle body 1 is provided with a feed port. A driving shaft 2, an intermediate shaft 3 and a stirring shaft 4 are arranged in the kettle body 1 in sequence from top to bottom.

[0041] The top end of the driving shaft 2 is rotatably connected to the kettle body 1 . A motor 11 is installed at the top end of the kettle body 1 . The motor 11 is connected to the driving shaft 2 so as to drive the driving shaft 2 to rotate.

[0042] The intermediate shaft 3 is coaxial with the driving shaft 2. The driving shaft 2 is provided with a column cavity, and a limiting cylinder 21 coaxial with the driving shaft 2 is fixed in the column cavity. A limiting shaft 31 is fixed at the top of the intermediate shaft 3. The limiting shaft 31 is coaxial with the intermediate shaft 3, and the limiting shaft 31 is slidably fitted in the limiting cylinder 21. A connecting spring 22 is also provided in the column cavity and sleeved on the outer peripheral side of the limiting cylinder 21. The two ends of the connecting spring 22 are fixedly connected to the driving shaft 2 and the intermediate shaft 3 respectively.

[0043] The stirring shaft 4 is coaxially connected to the intermediate shaft 3 for rotation. There are multiple stirring paddles 41, which are all placed in the kettle body 1. The multiple stirring paddles 41 are evenly spaced along the circumference of the stirring shaft 4. Each stirring paddle 41 is fixedly connected to the stirring shaft 4 through a connecting rod. When the stirring shaft 4 rotates, the stirring paddle 41 is driven to rotate through the connecting rod, and the stirring paddle 41 stirs the reaction material in the kettle body 1.

[0044] In addition, key references Figure 2, Figure 4 and Figure 8 , a first conical plate 32 is coaxially connected to the intermediate shaft 3, the first conical plate 32 is concave downward as a whole, and upper feeding holes 321 are evenly distributed on it. A second conical plate 43 is coaxially connected to the stirring shaft 4, the second conical plate 43 is concave downward as a whole, and lower feeding holes 431 are evenly distributed on it. The first conical plate 32 and the second conical plate 43 fit together up and down, and in the initial state, the upper feeding holes 321 and the lower feeding holes 431 partially overlap. A revolving groove can also be provided on the outer edge of the first conical plate 32, and the revolving groove is annular and coaxial with the first conical plate 32. A revolving ring 432 is provided on the outer edge of the second conical plate 43, and the revolving ring 432 is rotatably fitted in the revolving groove.

[0045] Continue to refer Figures 2 to 5 , a cavity is provided at the top of the stirring shaft 4, and a convex shaft 33 is provided at the bottom of the intermediate shaft 3 to extend into the cavity. An opening is provided on the side wall of the cavity, and a sliding member 42 is slidably arranged in the radial direction of the stirring shaft 4 through the opening. It can be understood that in this embodiment, the specific shape of the sliding member 42 can be a block, a strip, etc. A spring groove is provided on the bottom wall of the cavity and is provided on the stirring shaft 4. The spring groove extends along the sliding direction of the sliding member 42. The sliding member 42 has a support plate 421 that fits in the spring groove, and the support plate 421 is connected to the stirring shaft 4 through a return spring 422.

[0046] A limiting groove 331 is provided on the convex shaft 33, and one end of the sliding member 42 is slidably fitted in the limiting groove 331. An inclined surface 423 is provided at the end of the sliding member 42 located in the limiting groove 331. When the intermediate shaft 3 rotates, the sliding member 42 is pushed to rotate by the groove wall of the limiting groove 331, and the sliding member 42 pushes the stirring shaft 4 to rotate through the side wall of the opening. At the same time, the sliding member 42 is also subjected to the centrifugal force to slide toward the outside of the stirring shaft 4, and squeezes the reset spring 422, and the inclined surface 423 follows the sliding member 42 to slide toward the outside of the limiting groove 331. When the inclined surface 423 moves to the notch of the limiting groove 331, the rotating intermediate shaft 3 causes the notch edge of the limiting groove 331 to press against the inclined surface 423, so that the contact portion between the intermediate shaft 3 and the sliding member 42 is changed, and the sliding member 42 is deflected back a little relative to the intermediate shaft 3. At this time, the sliding member 42 deflects back a little with the stirring shaft 4 and the second conical plate 43, and the lower feeding hole 431 deflects back accordingly. During the deflection process, the overlapping portion of the lower feeding hole 431 and the upper feeding hole 321 increases.

[0047] In this embodiment, the number of the sliding member 42 , the return spring 422 , the spring slot, and the limiting slot 331 may be one, two, or another number, which is not limited here.

[0048] Continue to refer Figure 2 , Figure 3 , Figure 6 and Figure 7The carboxylic acid water reducer reaction kettle of the present invention further includes a collar 23 and a guide pipe 5 .

[0049] The collar 23 is vertically slidably sleeved on the drive shaft 2. The outer wall of the drive shaft 2 is provided with an annular retaining edge 24. The collar 23 is connected to the annular retaining edge 24 through an elastic member. In this embodiment, the elastic member can directly adopt a compression spring 231. The drive shaft 2 is provided with a moving groove extending along its radial direction. A moving block 25 is slidably fitted in the moving groove. The moving block 25 is connected to the drive shaft 2 through a return spring 251. A wedge structure is provided between the moving block 25 and the collar 23.

[0050] Specifically, the wedge structure includes a wedge block 232 disposed on the collar 23 and a wedge portion 252 formed on the moving block 25 , and the wedge surface of the wedge block 232 and the wedge surface of the wedge portion 252 fit each other.

[0051] When the drive shaft 2 rotates, centrifugal force is generated on the moving block 25, and the moving block 25 slides toward the outside of the drive shaft 2 under the action of the centrifugal force. The wedge-shaped portion 252 squeezes the wedge-shaped block 232 and forces the collar 23 to slide downward through the wedge-shaped block 232.

[0052] The material guide pipe 5 is L-shaped and includes a vertical pipe section 51 and an inclined pipe section 52 connected with a smooth transition. The top end of the vertical pipe section 51 is rotatably fitted in the feed port, and the free end of the inclined pipe section 52 is located above the first conical plate 32. A connecting frame 6 is provided between the material guide pipe 5 and the collar 23. One end of the connecting frame 6 is rotatably sleeved on the collar 23, and the other end is sleeved on the vertical pipe section 51 of the material guide pipe 5, that is, the vertical pipe section 51 of the material guide pipe 5 is penetrated through the other end of the connecting frame 6. A spiral groove 511 is provided on the outer wall of the vertical pipe section 51 of the material guide pipe 5. The spiral angle of the spiral groove 511 is greater than the friction angle. A spiral push rod is provided on the connecting frame 6 to fit in the spiral groove 511.

[0053] When the collar 23 slides down, it drives the connecting frame 6 to move downward. The connecting frame 6 drives the vertical pipe section 51 of the guide pipe 5 to rotate through the cooperation of the spiral push rod and the spiral groove 511, and the inclined pipe section 52 revolves accordingly, and its free end deflects above the first conical plate 32.

[0054] Continue to refer Figure 2 A movable gear ring 322 is provided on the outer periphery of the first conical plate 32, and a stationary gear ring 12 located above the movable gear ring 322 is fixed to the inner wall of the kettle body 1, and the teeth on the stationary gear ring 12 and the teeth on the movable gear ring 322 are oriented oppositely.

[0055] When the intermediate shaft 3 rotates, the first conical plate 32 drives the movable gear ring 322 to rotate, and the teeth on the movable gear ring 322 can contact the teeth on the stationary gear ring 12, and generate extrusion. Under the action of the extrusion force, the movable gear ring 322 slides downward, and drives the intermediate shaft 3 to slide downward through the first conical plate 32, and the connecting spring 22 is stretched. When the teeth on the movable gear ring 322 pass over the teeth on the stationary gear ring 12, the intermediate shaft 3, the first conical plate 32 and the movable gear ring 322 are reset under the elastic force of the connecting spring 22. This is repeated, and the movable gear ring 322 will continuously slide up and down during rotation, thereby causing the first conical plate 32 to vibrate.

[0056] refer to Figures 1 to 8 The working process of the carboxylic acid water reducer reactor of the present invention is as follows:

[0057] First, liquid raw materials are introduced into the kettle body 1 through the feed port, and the liquid raw materials flow into the bottom of the kettle body 1. Then, solid materials are introduced into the feed port, and the solid materials enter the kettle body 1 through the guide tube 5. At the same time, the motor 11 drives the drive shaft 2 to rotate, and the drive shaft 2 drives the intermediate shaft 3 to rotate through the limit cylinder 21 and the limit shaft 31, and the intermediate shaft 3 drives the stirring shaft 4 to rotate through the sliding member 42, that is, at this time, the drive shaft 2, the intermediate shaft 3 and the stirring shaft 4 arranged up and down rotate synchronously at the same time. The first conical plate 32 and the second conical plate 43 rotate accordingly.

[0058] The solid material flows out from the free end of the inclined pipe section 52 of the guide pipe 5, falls on the first conical plate 32, and then flows toward the center of the first conical plate 32 along the concave direction of the first conical plate 32. When the first conical plate 32 rotates, each part of the circumferential direction of the first conical plate 32 can receive the solid material. Combined with the flow of the solid material on the first conical plate 32, the solid material achieves the effect of paving on the first conical plate 32. During the paving process, the solid material falls downward through the overlapping part of the upper feed hole 321 and the lower feed hole 431, enters the bottom of the kettle body 1, and mixes with the liquid raw material. The stirring paddle 41 stirs the solid material and the liquid raw material, accelerating the mixing rate of the two.

[0059] When the moving block 25 rotates with the driving shaft 2, a centrifugal effect is generated, the moving block 25 slides outward, and squeezes the collar 23 downward through the wedge structure, the collar 23 drives the connecting frame 6 to move downward, and the connecting frame 6 drives the guide pipe 5 to rotate under the action of the spiral push rod and the spiral groove 511, and the free end of the inclined pipe section 52 of the guide pipe 5 gradually deflects toward the center line of the first conical plate 32.

[0060] This arrangement is to generate centrifugal force on the solid materials on the plate surface when the first conical plate 32 rotates, and the centrifugal force tends to make the solid materials slide to the outside of the first conical plate 32. At this time, it is difficult for the solid materials to flow to the center of the first conical plate 32, so that the spreading area on the first conical plate 32 is small. The corresponding deflection of the guide tube 5 can make the discharge part on the guide tube 5, that is, the above-mentioned free end, closer to the center of the first conical plate 32, so that the falling solid materials can flow downward on the first conical plate 32 and disperse upward under the action of centrifugal force, so as to achieve the effect of evenly spreading on the first conical plate 32. When the speed of the driving shaft 2 is higher, the centrifugal force is higher, the outward displacement of the moving block 25 and the downward displacement of the collar 23 are both larger, and the discharge part of the guide tube 5 is closer to the center of the first conical plate 32, so that each time the falling solid materials can be evenly spread on the first conical plate 32.

[0061] When the sliding member 42 rotates, it will slide outward under the action of centrifugal force, driving the inclined surface 423 to move to the notch of the limiting groove 331. The rotating intermediate shaft 3 will press the notch edge of the limiting groove 331 against the inclined surface 423. At this time, the contact part between the intermediate shaft 3 and the sliding member 42 is offset to the inside of the sliding member 42, and the sliding member 42 is equivalent to being deflected back a little along the circumference of the intermediate shaft 3. The sliding member 42 pushes the stirring shaft 4 and the second conical plate 43 to deflect back a little, and the overlapping part of the lower feeding hole 431 and the upper feeding hole 321 increases, thereby facilitating the passage of more solid materials. As can be seen from the above, the faster the rotation of the intermediate shaft 3, the stirring shaft 4 and the stirring paddle 41, the greater the centrifugal force, the greater the outward displacement of the sliding member 42, the greater the degree of return deflection of the sliding member 42 and the second conical plate 43, and the more overlapping parts of the lower feeding hole 431 and the upper feeding hole 321. At this time, the passing speed of the solid material is accelerated, that is, the feeding speed is accelerated. On the contrary, when the rotation of the stirring shaft 4 and the stirring paddle 41 slows down, the feeding speed of the solid material is also slowed down. Thereby, the feeding speed of the solid material can change with the change of the stirring speed, which not only ensures the entire reaction time and reaction process, but also ensures that the amount of solid material added can just react fully with the liquid raw material.

[0062] When the first conical plate 32 rotates, the movable gear ring 322 is pressed and contacted with the stationary gear ring 12. The movable gear ring 322 slides downward to avoid the stationary gear ring 12, thereby causing the connection spring 22 to lengthen. When the teeth on the movable gear ring 322 pass over the teeth on the stationary gear ring 12, the connection spring 22 pulls the movable gear ring 322 to reset. As a result, the movable gear ring 322 will continuously slide up and down during rotation, thereby causing the first conical plate 32 to vibrate. The vibrating first conical plate 32 is more conducive to the passage of solid materials and reduces blockage.
