Description

Technical Field

[0001] The invention relates to a delivery pump, in particular to a delivery pump for high-viscosity fluids, which is applied in the technical field of high-viscosity fluid delivery. Background Art

[0002] In the transportation of ultra-high viscosity fluids, single-screw screw pumps are generally used at present. It relies on the meshing of the screw and the bushing to produce volume changes in the suction chamber and the discharge chamber to transport the liquid. It is an internally meshed closed screw pump. The main working parts are composed of a bushing with a double-headed spiral cavity and a single-headed spiral screw meshed with it in the stator cavity. When the input shaft drives the rotor to make planetary rotation around the center of the stator through the universal joint, the stator-rotor pair continuously meshes to form a sealed cavity. These sealed cavities move axially at a uniform speed without changing their volume, and the high-viscosity fluid to be transported is transported from the inlet to the outlet through the stator-rotor pair.

The invention can stably deliver ultra-high viscosity fluids, ensure the continuity and stability of the delivery state, accurately control the delivery amount of high-viscosity fluids, realize the controllability of the delivery amount of high-viscosity fluids, reduce the impact of temperature on equipment, ensure continuous controllability of production, and extend service life.

[0004] The above scheme realizes the temperature control and continuous delivery of high-viscosity fluids, but it is easy for high-viscosity fluids to get clogged when using a screw pump, causing the motor to stall and damage the motor, affecting production efficiency and personnel safety. In addition, when conveying high-viscosity fluids, some high-viscosity fluids need to maintain a certain temperature, and may solidify after cooling, causing production interruptions, and subsequent cleaning is very cumbersome. Summary of the invention

[0008] The conveying device comprises a conveying support shell, the inner wall of which is fixedly connected with a feeding stator, a spiral rod is arranged inside the feeding stator, and a temperature control element and a temperature sensor are arranged inside the spiral rod;

[0009] A conveying intelligent controller is provided on one side of the driving part, and a main control module, a command module and a detection module are provided in the conveying intelligent controller. The main control module is electrically connected to the command module and the detection module respectively, the command module is electrically connected to the driving part and the temperature control element respectively, and the detection module is electrically connected to the detection button and the temperature sensor respectively.

[0010] In the above-mentioned delivery pump for high-viscosity fluid, the anti-blocking device arranged in the coupling is used to detect whether the delivery device will be blocked when delivering the high-viscosity fluid, and the high-viscosity fluid is softened by the temperature control element and temperature sensor arranged in the screw rod to solve the blockage of the delivery device, thereby improving production efficiency and ensuring personnel safety.

[0011] As a further improvement of the present application, the feeding stator is closely fitted with the spiral rod, and the material of the feeding stator is a high temperature resistant elastic material.

[0012] As a further improvement of the present application, the output end of the reduction box is fixedly connected to a driving rod, the end of the driving rod away from the reduction box is fixedly connected to the screw rod, and the conveying support shell is provided with a feed port and a discharge port.

[0013] As another improvement of the present application, a one-way valve 1 and a pressurizing mechanism are provided in the conveying support shell, the one-way valve 1 is fixedly connected to the conveying support shell, the one-way valve 1 is sleeved with the driving rod, the pressurizing mechanism is fixedly connected to the conveying support shell, a one-way valve 2 is provided on the conveying support shell, an air pressure sensor is provided on the conveying support shell, and the detection module is electrically connected to the air pressure sensor.

[0014] As another improved supplement of the present application, the pressurizing mechanism includes a driving gear, which is fixedly installed with the driving rod, meshing with the driven gear, and the side of the driven gear is rotatably connected with a rocker arm, and a piston is inserted into the end of the rocker arm away from the driven gear, and the piston is tightly fitted with the conveying support shell, and an annular fixing piece is fixedly connected to the inner wall of the conveying support shell, the annular fixing piece is rotatably connected with the driving rod, and the driven gear is inserted into the annular fixing piece.

The other output end of the negative pressure device is used to output high-viscosity fluid, and the instruction module is electrically connected to the solenoid valve.

[0017] To sum up, when the conveying device is blocked, since the output end of the driving member is not fixedly connected to the coupling, when the driving member cannot drive the coupling to rotate, the driving member continues to move, and the output end of the driving member drives the baffle to rotate and push the linkage plate, and the linkage plate drives the linkage rod to compress the spring. As the driving member moves, the linkage rod finally compresses the spring and triggers the detection button. After the detection button is triggered, the driving member stops moving immediately, and the temperature control element works to increase the temperature of the screw rod, so that the high-viscosity fluid can be softened to a certain extent and the blockage is alleviated. When the high-viscosity fluid softens to a certain extent and the screw rod can move, the compressed spring will push the linkage rod to make the screw rod rotate slightly, so that the linkage rod no longer triggers the detection button. When the detection button is no longer triggered, the driving member is started to continue to convey the high-viscosity fluid, which effectively solves the blockage of high-viscosity materials and improves production efficiency.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-Figure 5 A delivery pump for high-viscosity fluid is shown, including a base 5, on which a driving member 1, a reduction box 3, and a delivery device 4 are installed. A coupling 2 is installed at the output end of the driving member 1, and the driving member 1 is connected to the reduction box 3 through the coupling 2, and the reduction box 3 is connected to the delivery device 4.

[0031] An anti-blocking device 201 is arranged in the coupling 2, and the anti-blocking device 201 comprises an anti-blocking support shell 202, and the anti-blocking support shell 202 is installed on the input end of the reduction box 3, and the inner wall of the anti-blocking support shell 202 is fixedly connected with a spring 206, and the other end of the spring 206 is fixedly connected with a linkage rod 203, and the top of the linkage rod 203 is fixedly connected with a linkage plate 204, and a baffle 205 is arranged correspondingly at the top of the linkage plate 204, and a damping sleeve 208 is fixed at the output end of the driving member 1, and the input end of the coupling 2 is sleeved on the outer ring of the damping sleeve 208, and the damping sleeve 208 at the output end of the driving member 1 is fixed with the baffle 205, and the linkage rod 203 is slidably connected with the anti-blocking support shell 202 along the circumferential direction of the output end of the driving member 1, and a detection button 207 is arranged on the inner wall of the anti-blocking support shell 202. After the screw rod 404 is blocked, since the input end of the coupling 2 is sleeved on the damping sleeve The outer ring of 208, the output end of the driving member 1 drives the coupling 2 through the friction force of the damping sleeve 208. This arrangement can ensure that the driving member 1 will not be blocked due to the blockage of the screw rod 404. After the screw rod 404 is blocked, if the driving member 1 and the coupling 2 are rigidly connected, the driving member 1 cannot rotate either. The blocking of the driving member 1 may damage the driving member 1 or even cause it to be scrapped. Therefore, the coupling 2 is connected to the outer ring of the damping sleeve 208. The material and thickness of the damping sleeve 208 can be adjusted to control the friction force between the damping sleeve 208 and the input end of the coupling 2 so that it can drive the screw rod 404 to transport high-viscosity materials. When blocked, the output end of the driving member 1 can also overcome the friction force to rotate, so that the output end of the driving member 1 cannot drive the coupling 2 to drive the reduction box 3 to move, and then cooperate with the anti-blocking device 201 set in the coupling 2 to further protect the safety and stability of the driving member 1.

[0032] When the driving member 1 cannot drive the coupling 2 to rotate, the driving member 1 continues to move. The damping sleeve 208 at the output end of the driving member 1 drives the baffle 205 to rotate and push the linkage plate 204. The linkage plate 204 drives the linkage rod 203 to shrink the spring 206. As the driving member 1 moves, the linkage rod 203 compresses the spring 206 and triggers the detection button 207. After the detection button 207 is triggered, the driving member 1 stops moving immediately and is fixed in the current position until the spiral rod 404 is able to move. The compressed spring 206 will push the linkage rod 203 to make the spiral rod 404 rotate slightly, so that the linkage rod 203 no longer triggers the detection button 207. After the detection button 207 is released, the driving member 1 continues to move to continue to convey the high-viscosity fluid.

[0033] The conveying device 4 includes a conveying support shell 401, and a feeding stator 402 is fixedly connected to the inner wall of the conveying support shell 401. A screw rod 404 is arranged inside the feeding stator 402, and a temperature control element and a temperature sensor are arranged inside the screw rod 404. The temperature control element and the temperature sensor arranged in the screw rod 404 can adjust the temperature change speed according to the set temperature and ambient temperature, and collect temperature information through the temperature sensor, and form a closed-loop control with the temperature control element by feedback of the temperature information to achieve more precise control. The feeding stator 402 fits tightly with the screw rod 404, and the material of the feeding stator 402 is a high-temperature resistant elastic material. The high-temperature resistant elastic material used for the feeding stator 402 can make the feeding stator 402 and the screw rod 404 fit more closely, and the high-temperature resistant property can increase the types of materials that can be conveyed by the conveying device 4 and the viscosity of the conveyed materials.

[0034] A conveying intelligent controller 7 is provided on one side of the driving member 1, and a main control module, a command module, and a detection module are provided in the conveying intelligent controller 7. The main control module is electrically connected to the command module and the detection module respectively, the command module is electrically connected to the driving member 1 and the temperature control element respectively, and the detection module is electrically connected to the detection button 207 and the temperature sensor respectively.

[0035] During the normal operation of the conveying pump, the output end of the driving member 1 drives the reduction box 3 to move through the coupling 2. The output end of the reduction box 3 is fixedly connected to the driving rod 403. The end of the driving rod 403 away from the reduction box 3 is fixedly connected to the screw rod 404. The conveying support shell 401 is provided with a feed port and a discharge port. The output end of the reduction box 3 drives the driving rod 403 to move, and the driving rod 403 drives the screw rod 404 to move, so as to transport the material from the feed port to the discharge port.

[0036] The coupling 2 is fixedly connected to the input end of the reduction box 3, but the output end of the driving member 1 is sleeved with the input end of the coupling 2. When the conveying device 4 is blocked, since the output end of the driving member 1 is sleeved with the input end of the coupling 2 through the damping sleeve 208, when the driving member 1 cannot drive the coupling 2 to rotate, the driving member 1 still continues to move, and the output end of the driving member 1 drives the baffle 205 to rotate, pushing the linkage plate 204, and the linkage plate 204 drives the linkage rod 203 to compress the spring 206. With the movement of the driving member 1, the linkage rod 203 finally compresses the spring 206 and triggers the detection button 207. The main control module of the conveying intelligent controller 7 is The detection module collects the status information of the detection button 207. After the main control module detects that the status information of the button changes from untriggered to triggered, the instruction module is immediately used to control the driving component 1 to stop moving, so that it is fixed in the current position, and the temperature control element is controlled to work, so that the temperature of the spiral rod 404 is rapidly increased to the set temperature (the main control module is preset with the set temperature in the current state). At the same time, the temperature information of the temperature sensor is collected through the detection module, and the temperature information is compared and calculated with the set temperature, so that the temperature control element can flexibly adjust the power according to the difference between the temperature information and the set temperature, so that the heating of the spiral rod 404 is efficient and accurate.

[0037] After the temperature in the conveying device 4 rises, the high-viscosity fluid softens, allowing the screw rod 404 to move, and the compressed spring 206 will push the linkage rod 203, causing the screw rod 404 to rotate slightly, so that the linkage rod 203 no longer triggers the detection button 207. After the detection module collects the button status information and finds that it has changed to untriggered, it sends the status information to the main control module. The main control module controls the driving component 1 to move again through the instruction module, driving the screw rod 404, so that the conveying device 4 continues to convey the high-viscosity fluid.

[0038] The second implementation method:

[0039] Figure 1-Figure 4 and Figure 6-Figure 8A delivery pump for high-viscosity fluid is shown. Different from the first embodiment, a one-way valve 405 and a pressurizing mechanism 407 are additionally provided in the delivery support housing 401. The one-way valve 405 is fixedly connected to the delivery support housing 401. The one-way valve 405 is sleeved with the driving rod 403. The pressurizing mechanism 407 is fixedly connected to the delivery support housing 401. A one-way valve 406 is provided on the delivery support housing 401. A pressure sensor 414 is provided on the delivery support housing 401. The detection module is electrically connected to the air pressure sensor 414; the pressurizing mechanism 407 includes a driving gear 408, which is fixedly installed on the driving rod 403, and the driving gear 408 is meshed with the driven gear 409. The side of the driven gear 409 is rotatably connected to a rocker arm 410, and the end of the rocker arm 410 away from the driven gear 409 is plugged with a piston 411, and the piston 411 is tightly fitted with the conveying support shell 401, and the inner wall of the conveying support shell 401 is fixedly connected to the annular fixing member 41 3. The annular fixing member 413 is rotatably connected to the driving rod 403, and the driven gear 409 is inserted on the annular fixing member 413; an auxiliary turntable 412 is rotatably connected to the annular fixing member 413, and two rocker arms 410 are provided, and the two rocker arms 410 are rotatably connected to the corresponding driven gear 409 and the auxiliary turntable 412 respectively; during operation, the driving rod 403 drives the driving gear 408 to rotate, and the driving gear 408 drives the driven gear 409 to rotate, and the driven gear 409 rotates to drive the rocker arm 410 to perform circular arc reciprocating operation, and the rocker arm 410 drives the piston 411 to reciprocate along the driving rod 403, and the piston 411 drives the other rocker arm 410 to move synchronously, and drives the auxiliary turntable 412 to rotate synchronously, and the auxiliary turntable 412 and the driven gear 409 move synchronously, which can maintain the stability of the reciprocating motion process of the piston 411, and the annular fixing member 413 can stably mesh the driven gear 409 with the driving gear 408 without affecting the action of the driving rod 403.

[0040] During the operation of the pressurizing mechanism 407, stable pressurization is achieved through the one-way valve 405 and the one-way valve 406. The piston 411 is pushed forward to push open the one-way valve 405. Due to the pressure difference between the inside and outside, the one-way valve 406 will be fixed and cannot be opened, so that the piston 411 fills the gas between it and the one-way valve 405 into the screw rod 404. When the piston 411 retracts backward, it is necessary to inhale gas to open the one-way valve 406 and inhale external gas. Due to the pressure difference, the one-way valve 405 cannot be opened. When the piston 411 retracts to the end, it is no longer necessary to inhale external gas, and the pressure difference between the inside and outside is balanced. At this time, the piston 411 is pushed forward again to compress the gas.

[0041] A negative pressure device 6 is also provided at the discharge port of the conveying support shell 401, and the negative pressure device 6 is fixedly connected to the conveying support shell 401. The negative pressure device 6 is provided with an input end and two output ends. One output end of the negative pressure device 6 is connected to an external gas source, and an electromagnetic valve is installed between the two to form a negative pressure at the discharge port of the conveying support shell 401. The other output end of the negative pressure device 6 is used to output a high-viscosity fluid. The instruction module is electrically connected to the electromagnetic valve, and the electromagnetic valve is opened. The external gas source forms a negative pressure in the internal cavity of the negative pressure device 6, and the high-viscosity fluid is discharged from the conveying device 4. The high-viscosity fluid is sucked out at the discharge port. Due to the ultra-high viscosity of the high-viscosity fluid, the high-viscosity fluid will not enter the pipeline of the external gas source along with the absorbed gas, but will slowly flow along the inner wall of the negative pressure device 6 and be squeezed out from the other output end of the negative pressure device 6 by the subsequent high-viscosity fluid. At the same time, due to the operation of the pressurizing mechanism 407, the air pressure in the conveying support shell 401 is higher than the conventional external atmospheric pressure. Therefore, the high-viscosity fluid sucked out from the conveying device 4 has a higher flow rate than the high-viscosity fluid flowing out of the output end, so that the high-viscosity fluid flowing out of the output end will not return to the negative pressure device 6 due to the negative pressure.

[0042] When using a delivery pump to deliver high-viscosity fluid, a portion of the high-viscosity fluid cannot be blocked by increasing the temperature to improve fluidity. In order to improve the applicability of the delivery pump, a pressurizing mechanism 407 and a negative pressure device 6 are added. During the operation of the delivery pump, the pressurizing mechanism 407 will continue to operate to improve the self-priming ability of the delivery pump, so that the delivery device 4 can deliver the high-viscosity fluid more smoothly. The main control module collects the air pressure data of the air pressure sensor 414 through the detection module, and compares the air pressure data with the specified air pressure (the main control module is preset with the specified air pressure in the current state). When the air pressure is When the pressure data exceeds the specified air pressure and continues to increase, it means that the screw rod 404 is blocked. At this time, the instruction module controls the solenoid valve to open, and controls the external air source to operate, so that the negative pressure device 6 works, and the high-viscosity fluid in the screw rod 404 is sucked out from the discharge port of the conveying support shell 401, so that the screw rod 404 is no longer blocked and normal operation is restored. When the screw rod 404 is no longer blocked, the air pressure data gradually decreases until the difference between the air pressure data and the specified air pressure is within a certain error range. The instruction module controls the solenoid valve to close, and then controls the external air source to stop operating, so that the negative pressure device 6 stops running.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
