Description

Technical Field

[0001] This invention relates to the field of heat exchange technology in silica production, specifically to a silica slurry heat exchange device. Background Technology

[0002] A typical heat exchange device for silica slurry consists of a heat exchange frame, heat exchange components, a feed inlet, a discharge outlet, and control components.

[0003] Patent publication number CN218673243U relates to a heat exchange device for silica slurry, belonging to the field of silica production. It includes a tank and a heat exchange assembly. The tank comprises a first cover, a cylinder, and a second cover, detachably connected from top to bottom. The first cover has a material inlet, and the second cover has a material outlet. A water inlet is located on one side of the bottom of the cylinder, and a water outlet is located on one side of the top. The heat exchange assembly is disposed within the cylinder and includes multiple pipes, each including at least one air inlet pipe, at least one air outlet pipe, and multiple heat exchange tubes. These pipes are evenly distributed within the cylinder, and adjacent pipes are connected by connecting pipes, allowing steam to flow in multiple directions to ensure uniform heat exchange, prevent the silica slurry from forming a gel, and avoid blockage. The outer walls of the pipes are coated with a corrosion-resistant layer to prevent corrosion, extend service life, and reduce maintenance costs.

[0004] In the aforementioned patent, the outer wall of the pipeline is coated with a corrosion-resistant layer, which can prevent pipeline corrosion, improve service life, and reduce maintenance costs. However, it is difficult to prevent heat exchange dead zones caused by uneven slurry concentration. Uneven concentration will lead to differences in slurry fluidity, causing high-concentration slurry to deposit and form a thermal resistance layer, thereby reducing the heat transfer efficiency between the heat exchange surface and the slurry. Therefore, it is necessary to design a precipitated silica slurry heat exchange device that is highly practical and prevents uneven slurry concentration. Summary of the Invention

[0005] The purpose of this invention is to provide a heat exchange device for silica slurry to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat exchange device for silica slurry, comprising a heat exchange frame and a heat exchange module. An arc-shaped frame is fixedly installed on the top of the heat exchange frame, and a curved frame is fixedly installed on the bottom of the heat exchange frame. An inlet is provided at the top of the arc-shaped frame, and an outlet is provided at the bottom of the curved frame. The heat exchange module comprises a heat exchange component, a rotating rod, a rotating plate, a hollow frame, a connecting rod, a rotating wheel, a connecting plate, a connecting spring, and an arc-shaped block. The heat exchange component is disposed inside the heat exchange frame. The rotating rod rotatably passes through the rear side of the arc-shaped frame. The rotating plate is fixedly installed on the circumferential surface of the rotating rod. The core frame is slidably installed on the circumferential surface of the heat exchange component. The connecting rod is fixedly installed on the top of the hollow frame. The rotating wheel is rotatably installed on the inner wall of the connecting rod. The connecting plate is fixedly installed on the front and rear walls of the connecting rod. The connecting spring is set between the connecting plate and the heat exchange frame. When the connecting plate moves downward, it pulls the connecting spring. The connecting spring deforms and stores force due to the pull of the connecting plate. After the rotating plate continues to rotate clockwise and disengages from the connecting rod, the connecting spring can drive the connecting plate to return to its original position. The arc-shaped block is fixedly installed on the left side of the connecting rod. When the rotating plate rotates clockwise, it contacts the slurry and strikes the undispersed precipitated silica lumps in the slurry.

[0007] According to the above technical solution, a material vent is provided at the top of the arc-shaped frame, a water outlet is provided on the left side of the arc-shaped frame, and a water inlet and vent are provided on the right side of the arc-shaped frame. The hollow frame moves back and forth to mechanically remove the scale layer on the top of the heat exchange component.

[0008] According to the above technical solution, a drain outlet is provided on the left side of the curved frame, and a water inlet is provided on the right side of the curved frame. After water is introduced, it is used for washing water. The bottom of the inner wall of the arc frame is set as an inclined surface. The connecting plate moves upward and resets, which drives the connecting rod to move upward. The upward movement of the connecting rod drives the hollow frame to move upward.

[0009] According to the above technical solution, it also includes an extrusion module and an injection module. The extrusion module is used to prevent slurry from accumulating at the bottom of the inner wall of the arc-shaped frame. The injection module is used to add a dispersant to the slurry. The extrusion module includes an extrusion rod, an extrusion plate, an anti-sticking spring, an extrusion groove, and a T-shaped plate. The extrusion rod slides through the bottom of the inner wall of the arc-shaped frame. The extrusion plate is fixedly installed on the circumferential surface of the extrusion rod. The anti-sticking spring is disposed between the extrusion plate and the arc-shaped frame. The extrusion plate moves downward to extrude the anti-sticking spring. The anti-sticking spring deforms and stores force under the extrusion of the extrusion plate. After the extrusion plate is separated from the arc-shaped block, the extrusion plate can be driven to reset by the anti-sticking spring. The extrusion groove is opened on the front side of the arc-shaped frame. The T-shaped plate slides through the rear side of the inner wall of the extrusion groove. The extrusion plate moves back and forth to push the slurry at the bottom of the inner wall of the arc-shaped frame.

[0010] According to the above technical solution, the extrusion module further includes a return spring and a curved panel. The return spring is disposed between the extrusion groove and the T-shaped plate. The T-shaped plate moves forward and pulls the return spring. The return spring deforms and stores force due to the pull of the T-shaped plate. After the T-shaped plate is separated from the extrusion plate, the return spring can drive the T-shaped plate to return to its original position. The curved panel is fixedly installed on the top of the extrusion rod. The T-shaped plate moves backward and returns to its original position under the elastic force of the return spring.

[0011] According to the above technical solution, the extrusion plate contacts the arc-shaped block, the extrusion plate moves downward to contact the inclined surface of the T-shaped plate and extrudes the T-shaped plate, the extrusion plate contacts the inner wall of the arc-shaped frame, the rear side of the T-shaped plate is set as an inclined surface, and the T-shaped plate contacts the extrusion plate.

[0012] According to the above technical solution, the injection module includes an injection frame, an injection pipe, an injection hole, an injection plate, a rubber block, and an injection spring. The rubber block deforms under the pressure of the injection plate, releasing the seal on the injection pipe. The injection frame is fixedly installed on the right side of the arc-shaped frame, and the injection pipe is fixedly installed on the left side of the injection frame. The injection hole is opened on the circumferential surface of the injection pipe. The injection plate is slidably installed on the inner wall of the injection hole, and the rubber block is fixedly installed on the inner wall of the injection pipe. The injection spring is disposed between the injection pipe and the injection plate. The injection plate moves downward to compress the injection spring, causing the injection spring to deform and store force. After the injection plate disengages from the arc-shaped frame, the injection spring can drive the injection plate to reset. The inner wall of the arc-shaped frame is provided with a dispersant, and the thin-walled float slowly descends to contact the injection pipe and seal it.

[0013] According to the above technical solution, the injection module further includes an installation rod and a thin-walled float. The installation rod is fixedly installed on the inner wall of the injection frame, and the thin-walled float is slidably installed on the circumferential surface of the installation rod. The thin-walled float slowly descends to contact the injection pipe and seals the injection pipe.

[0014] According to the above technical solution, the thin-walled floating block is in contact with the inner wall of the injection frame, the rubber block is in contact with the inner wall of the injection hole, the injection pipe passes through the right side of the injection frame, and after the injection plate moves upward and resets, the rubber block returns to its initial shape under the action of its own elasticity.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] This invention utilizes a rotating plate that rotates clockwise to contact the slurry and strike undispersed silica lumps within it. This striking action forcibly disperses the slurry particles, preventing heat exchange dead zones caused by uneven concentrations. This also prevents localized overheating of the slurry due to differences in thermal conductivity caused by silica lumps, which can negatively impact heat exchange efficiency. Furthermore, the hollow frame moves back and forth to mechanically remove scale from the top of the heat exchange assembly. The mechanical friction breaks down the scale deposits, maintaining the heat exchange surface close to its initial state and preventing heat exchange efficiency degradation caused by scaling. Mechanical descaling also prevents abnormal local temperatures in the heat exchange assembly, thus avoiding slurry decomposition or deformation of the heat exchange assembly.

[0017] This invention uses a reciprocating pressing plate to push the slurry at the bottom of the inner wall of the arc-shaped frame, thereby preventing the slurry from accumulating at the bottom of the inner wall of the arc-shaped frame. The reciprocating pushing of the pressing plate can speed up the discharge speed, thereby shortening the discharge time. Furthermore, the strong pushing can fully discharge the slurry at the bottom of the arc-shaped frame, significantly reducing the residual rate and thus reducing slurry waste.

[0018] (3) In this invention, the operator can observe whether the extrusion plate is stuck due to excessive slurry viscosity by observing the movement of the T-shaped plate. If the adhesion is not dealt with in time, the extrusion plate will be stuck after the slurry solidifies. When it is observed that the extrusion plate is stuck due to excessive slurry viscosity, the operator can manually push the T-shaped plate to the rear to reset it, thereby ensuring the pushing effect of the extrusion plate.

[0019] (4) In this invention, the rubber block restores its initial shape and restores the seal on the injection pipe. The reciprocating deformation of the rubber block causes the dispersant to mix with the slurry intermittently. The intermittent mixing of the dispersant with the slurry allows for relatively precise control of the amount, thereby avoiding fluctuations in slurry quality caused by excessive addition.

[0020] (5) In this invention, the thin-walled floating block descends slowly and contacts the injection pipe and seals the injection pipe, thereby preventing the dispersant from being contaminated by the slurry entering the injection frame due to the failure of the dispersant to be replenished in time. By blocking the backflow of the slurry in time, the dispersant can be prevented from being contaminated by the slurry, thereby preventing the dispersant from failing due to the mixing of impurities.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0032] Please see Figure 1-8This invention provides a technical solution: a heat exchange device for silica slurry, comprising a heat exchange frame 1 and a heat exchange module. An arc-shaped frame 2 is fixedly installed on the top of the heat exchange frame 1, and a curved frame 3 is fixedly installed on the bottom of the heat exchange frame 1. The arc-shaped frame 2 has a feed inlet at its top, and the curved frame 3 has a discharge outlet at its bottom. The heat exchange module includes a heat exchange component 4, a rotating rod 5, a rotating plate 6, a hollow frame 7, a connecting rod 8, a rotating wheel 9, a connecting plate 10, a connecting spring 11, and an arc-shaped block 12. The heat exchange component 4 is disposed inside the heat exchange frame 1. The rotating rod 5 rotates through the rear side of the arc-shaped frame 2. The rotating plate 6 is fixedly installed on the circumferential surface of the rotating rod 5. The hollow frame 7 is slidably installed on the circumferential surface of the heat exchange component 4. The connecting rod 8 is fixedly installed on the hollow frame 1. At the top of the core frame 7, the rotating wheel 9 is rotatably installed on the inner wall of the connecting rod 8. The connecting plate 10 is fixedly installed on the front and rear walls of the connecting rod 8. The connecting spring 11 is set between the connecting plate 10 and the heat exchange frame 1. When the connecting plate 10 moves downward, it pulls the connecting spring 11. The connecting spring 11 deforms and stores force due to the pull of the connecting plate 10. After the rotating plate 6 continues to rotate clockwise and disengages from the connecting rod 8, the connecting spring 11 can drive the connecting plate 10 to reset. The arc-shaped block 12 is fixedly installed on the left side of the connecting rod 8. The striking action forcibly disperses the slurry particles, avoiding heat exchange dead zones caused by uneven local concentration, and thus preventing the precipitated silica lumps from causing local overheating of the slurry due to differences in thermal conductivity, which would affect the heat exchange effect.

[0033] The top of the arc-shaped frame 2 is provided with a material vent, the left side of the arc-shaped frame 2 is provided with a water outlet, and the right side of the arc-shaped frame 2 is provided with a water inlet and vent. The hollow frame 7 moves back and forth to mechanically remove the scale layer on the top of the heat exchange component 4. The mechanical friction breaks the scale deposit, which can maintain the heat exchange surface close to the initial state, thereby avoiding the heat exchange efficiency decay caused by scale.

[0034] The curved frame 3 has a drain outlet on the left side and a water inlet on the right side. After water is introduced, it is used for washing water. The bottom of the inner wall of the arc frame 2 is set as a slope. The connecting plate 10 moves upward and resets, which drives the connecting rod 8 to move upward. The connecting rod 8 moves upward and drives the hollow frame 7 to move upward. Mechanical descaling can prevent local temperature abnormalities in the heat exchange component 4, thereby avoiding slurry decomposition or deformation of the heat exchange component 4.

[0035] In this embodiment, during operation, the slurry enters through the inlet on the arc-shaped frame 2 and flows out through the outlet on the curved frame 3. Washing water enters through the inlet on the curved frame 3 and flows out through the outlet on the arc-shaped frame 2. During the washing process, the slurry contacts the heat exchange component 4 inside the heat exchange frame 1 for heat exchange and temperature increase, improving the washing effect. The steam used for heat exchange enters from the top left side of the heat exchange component 4, passes through the interior of the heat exchange component 4, and flows out from the top right side of the heat exchange component 4. A servo motor is installed on the rear side of the arc-shaped frame 2, and the output end of the servo motor is fixedly connected to the rotating rod 5. When the slurry enters the heat exchange frame 1 through the inlet on the arc-shaped frame 2, the servo motor drives the rotating rod 5 to rotate clockwise. The clockwise rotation of the rotating rod 5 drives the rotating plate 6 to rotate clockwise, and the clockwise rotation of the rotating plate 6 interacts with the slurry... The rotating plate 6 contacts and strikes the undispersed silica lumps in the slurry, thereby preventing local overheating of the slurry due to differences in thermal conductivity, which would affect the heat exchange effect. At the same time, the rotating plate 6 rotates clockwise and contacts the top of the connecting rod 8, squeezing the connecting rod 8. The connecting rod 8 moves downward under the pressure of the rotating plate 6, which in turn moves the connecting plate 10 downward. After the rotating plate 6 continues to rotate clockwise and disengages from the connecting rod 8, the connecting plate 10 moves upward and resets under the elastic force of the connecting spring 11. The upward movement of the connecting plate 10 drives the connecting rod 8 upward, which in turn drives the hollow frame 7 upward. The reciprocating movement of the hollow frame 7 mechanically removes the scale layer on the top of the heat exchange component 4, thereby avoiding the reduction in heat exchange efficiency caused by scaling. Example 2

[0036] Please see Figure 1-8 Based on Embodiment 1, this embodiment further includes an extrusion module and an injection module. The extrusion module is used to prevent slurry from accumulating at the bottom of the inner wall of the arc-shaped frame 2, and the injection module is used to add a dispersant to the slurry. The extrusion module includes an extrusion rod 131, an extrusion plate 132, an anti-sticking spring 133, an extrusion groove 134, and a T-shaped plate 135. The extrusion rod 131 slides through the bottom of the inner wall of the arc-shaped frame 2, and the extrusion plate 132 is fixedly installed on the circumferential surface of the extrusion rod 131. The anti-sticking spring 133 is disposed between the extrusion plate 132 and the arc-shaped frame 2. The downward movement of the extrusion plate 132 prevents the slurry from accumulating at the bottom of the inner wall of the arc-shaped frame 2. The sticking spring 133 is squeezed, and the anti-sticking spring 133 is deformed and stores force under the pressure of the extrusion plate 132. After the extrusion plate 132 is separated from the arc block 12, the anti-sticking spring 133 can drive the extrusion plate 132 to reset. The extrusion groove 134 is opened on the front side of the arc frame 2. The T-shaped plate 135 slides through the rear side of the inner wall of the extrusion groove 134. The back-and-forth pushing of the extrusion plate 132 can speed up the discharge speed, thereby shortening the discharge time. Moreover, the strong pushing can fully discharge the slurry at the bottom of the arc frame 2, significantly reducing the residual rate and thus reducing the waste of slurry.

[0037] The extrusion module also includes a return spring 136 and a curved panel 137. The return spring 136 is disposed between the extrusion groove 134 and the T-shaped plate 135. When the T-shaped plate 135 moves forward, it pulls the return spring 136. The return spring 136 deforms and stores force under the pull of the T-shaped plate 135. After the T-shaped plate 135 is separated from the extrusion plate 132, the return spring 136 can drive the T-shaped plate 135 to return to its original position. The curved panel 137 is fixedly installed on the top of the extrusion rod 131. The T-shaped plate 135 moves backward to return to its original position under the elastic force of the return spring 136. When it is observed that the extrusion plate 132 is stuck due to excessive slurry viscosity, the operator can manually push the T-shaped plate 135 to move backward to return to its original position, thereby ensuring the pushing effect of the extrusion plate 132.

[0038] The extrusion plate 132 contacts the arc block 12, and the extrusion plate 132 moves downward to contact the inclined surface of the T-shaped plate 135 and extrudes the T-shaped plate 135. The extrusion plate 132 contacts the inner wall of the arc frame 2. The rear side of the T-shaped plate 135 is set as an inclined surface, and the T-shaped plate 135 contacts the extrusion plate 132.

[0039] The injection module includes an injection frame 141, an injection pipe 142, an injection hole 143, an injection plate 144, a rubber block 145, and an injection spring 146. The injection frame 141 is fixedly installed on the right side of the arc-shaped frame 2, the injection pipe 142 is fixedly installed on the left side of the injection frame 141, the injection hole 143 is opened on the circumferential surface of the injection pipe 142, the injection plate 144 is slidably installed on the inner wall of the injection hole 143, the rubber block 145 is fixedly installed on the inner wall of the injection pipe 142, and the injection spring 146 is disposed between the injection pipe 142 and the injection plate 144. 144 moves downward to compress the injection spring 146. The injection spring 146 deforms and stores force under the compression of the injection plate 144. After the injection plate 144 is separated from the curved panel 137, the injection spring 146 can drive the injection plate 144 to reset. The inner wall of the arc frame 2 is provided with a dispersant. The thin-walled float 148 slowly descends to contact the injection pipe 142 and seals the injection pipe 142. The dispersant is intermittently mixed with the slurry, which can control the amount relatively accurately, thereby avoiding fluctuations in slurry quality caused by excessive addition.

[0040] The injection module also includes an installation rod 147 and a thin-walled float 148. The installation rod 147 is fixedly installed on the inner wall of the injection frame 141, and the thin-walled float 148 is slidably installed on the circumferential surface of the installation rod 147. The thin-walled float 148 slowly descends to contact the injection pipe 142 and seals the injection pipe 142. By timely blocking the backflow of slurry, the dispersant can be prevented from being contaminated by the slurry, thereby avoiding the failure of the dispersant due to the mixing of impurities.

[0041] The thin-walled float 148 contacts the inner wall of the injection frame 141, the rubber block 145 contacts the inner wall of the injection hole 143, the injection pipe 142 passes through the right side of the injection frame 141, and after the injection plate 144 moves upward and resets, the rubber block 145 returns to its initial shape under the action of its own elasticity.

[0042] In this embodiment, during operation, the connecting rod 8 moves downward, causing the arc-shaped block 12 to move downward. The arc-shaped block 12 moves downward and contacts the extrusion plate 132, extruding and pressing it. The extrusion plate 132 moves downward under the pressure of the arc-shaped block 12. After the rotating plate 6 continues to rotate clockwise and disengages from the connecting rod 8, the connecting plate 10 moves upward and resets under the elastic force of the connecting spring 11. The upward reset of the connecting plate 10 causes the connecting rod 8 to move upward, which in turn causes the arc-shaped block 12 to move upward and reset. The arc-shaped block 12 moves upward and resets, disengaging from the extrusion plate 132. After the extrusion plate 132 disengages from the arc-shaped block 12, it moves upward and resets under the elastic force of the anti-sticking spring 133. The reciprocating movement of the extrusion plate 132 pushes the slurry at the bottom of the inner wall of the arc-shaped frame 2, thereby preventing the slurry from accumulating inside the arc-shaped frame 2. At the bottom of the wall, the extrusion plate 132 moves downward and contacts the inclined surface of the T-shaped plate 135, extruding and pressing the T-shaped plate 135. The T-shaped plate 135 moves forward under the pressure of the extrusion plate 132. When the extrusion plate 132 moves upward and resets under the elastic force of the anti-sticking spring 133, the extrusion plate 132 moves upward and disengages from the contact with the T-shaped plate 135. After the T-shaped plate 135 disengages from the contact with the extrusion plate 132, it moves backward and resets under the elastic force of the reset spring 136. The operator can observe whether the extrusion plate 132 is sticking due to excessive slurry viscosity by observing the movement of the T-shaped plate 135. If it is observed that the extrusion plate 132 is sticking due to excessive slurry viscosity, the operator can manually push the T-shaped plate 135 backward to reset. The T-shaped plate 135 moves backward to extrude and press the extrusion plate 132, thereby assisting the extrusion plate 132 in resetting.

[0043] The extrusion plate 132 moves downward, causing the extrusion rod 131 and the curved panel 137 to move downward. The curved panel 137 moves downward and contacts the injection plate 144, extruding it. The injection plate 144 moves downward under the pressure of the curved panel 137, and then contacts the rubber block 145, extruding it. The rubber block 145 deforms under the pressure of the injection plate 144, releasing the seal on the injection pipe 142. After the seal on the injection pipe 142 is released, the dispersant inside the injection frame 141 mixes with the slurry through the injection pipe 142. When the extrusion plate 132 moves upward and resets under the elastic force of the anti-sticking spring 133, the upward movement of the extrusion plate 132 causes the extrusion rod 131 and the curved panel 137 to move upward and reset. The curved panel 137 moves upward to reset and disengage from the injection plate 144. After the injection plate 144 disengages from the curved panel 137, it moves upward to reset under the elastic force of the injection spring 146. After the injection plate 144 moves upward to reset, the rubber block 145 returns to its initial shape under its own elastic force. The rubber block 145 returns to its initial shape and restores the seal on the injection pipe 142. The reciprocating deformation of the rubber block 145 causes the dispersant to mix intermittently with the slurry. If the dispersant is not replenished in time, the dispersant gradually decreases, causing the thin-walled float 148 to slowly descend. The thin-walled float 148 slowly descends and contacts the injection pipe 142, sealing the injection pipe 142. This prevents the slurry from entering the injection frame 141 and causing dispersant contamination due to the lack of timely replenishment of the dispersant.
