Description

Technical Field

[0001] The invention relates to the technical field of petrochemical processing, and in particular to a stirring device for petrochemical processing. Background Art

[0002] In the process of petrochemical production and processing, stirring is often required, for example, stirring is used to improve the mixing uniformity of chemicals and then speed up the reaction rate. Petrochemical products are often viscous and easy to adhere to the inner wall of the stirring vessel. The number of these adhered substances will increase over time, not only occupying a certain space, but also prone to irregular shedding, thereby affecting the product quality of the stirred substances and being detrimental to product quality control. During the processing of the existing stirring device, the stirring device is often unable to be cleaned in a timely and convenient manner. For example, the Chinese utility model patent with application number 202120420087.3 provides a stirring device for petrochemical industry that is easy to clean. When cleaning, the device needs to use a cleaning roller to rub against the inner wall of the stirring barrel for cleaning. In the non-cleaning state, the cleaning roller needs to be removed from the stirring barrel, and in order to achieve a good cleaning effect, a sewage discharge system needs to be added to discharge the sewage, which increases the complexity of cleaning and the cost of cleaning, highlighting its shortcomings.

The guide plate 40 is connected to a plurality of horizontal guide rollers 42 for equiangular rotation in a circle. The guide plate 40 is inserted into the arc groove 211 through a gap. The annular inner wall of the arc groove 211 rolls and rubs against the outer circumferential wall of the adjacent guide roller 42, so that the guide plate 40 is adjusted by the rolling friction between the guide roller 42 and the annular inner wall of the arc groove 211. 0 and the guidance of the speed regulating motor 38, the mounting seat 39 is connected to a horizontal toggle pin 43 for sliding left and right, a horizontal front compression spring 44 is fixed to the right end of the toggle pin 43, and a horizontal front contact roller 45 is rotatably connected to the left part, and the rolling of the front contact roller 45 can reduce the friction with the toggle rod of the toggle button 46, thereby reducing the wear on the toggle rod of the toggle button 46, the rear end of the front compression spring 44 is fixed to the right end of the inner wall of the mounting seat 39, and the compressible characteristic of the front compression spring 44 can enable the front contact roller 45 to toggle the toggle rod of the toggle button 46 to achieve smooth toggle and final passage through the contraction of the toggle pin 43, the left front part of the support frame 2 is fixed with a toggle button 46, and the front end is fixed with a horizontal controller 47, the left left part of the top of the base 1 is fixed with a vertical left collecting groove 48, and the right right part of the top is fixed with a vertical right collecting groove 49, and the left collecting groove 48 and the right collecting groove 49 are respectively fixed with a discharge cylinder 50.

[0022] The self-reset button 34, the solenoid valve 36, the speed regulating motor 38, the toggle button 46 and the controller 47 are electrically connected, the controller 47 is externally connected to a power supply, the lower pinion 17 is meshed with the rear arc-shaped rack 15, the large gear 18 is meshed with the upper pinion 8, the two rear light rods 25 are gap-inserted with the two rear compression springs 26, the two middle compression springs 33 are gap-inserted with the two front light rods 29, and the driving gear 41 is always meshed with the front arc-shaped rack 22 during the rolling friction between the guide roller 42 and the arc groove 211, and the transmission seat 23 is inserted into the bottom of the arc groove 211 when the rear compression spring 26 is not deformed, and when the guide plate 40 enters the bottom of the arc groove 211, the guide roller 42 can press the transmission seat 23 so that The rear compression spring 26 is elastically compressed and causes the transmission seat 23 to withdraw from the arc groove 211. When the middle compression spring 33 is not deformed, the lower pressing seat 31 is above the self-reset button 34 and does not contact the self-reset button 34. When the middle compression spring 33 is elastically compressed, the lower pressing seat 31 can press the self-reset button 34 downward. When the self-reset button 34 is pressed, the solenoid valve 36 can be opened by the controller 47. When the self-reset button 34 is reset, the solenoid valve 36 can be closed by the controller 47. When the toggle button 46 is toggled downward, the speed regulating motor 38 can be controlled to rotate at a low speed by the controller 47. When the toggle button 46 is toggled upward, the speed regulating motor 38 can be controlled to rotate at a high speed by the controller 47.

[0023] When the speed regulating motor 38 is powered on and rotated, the meshing of the driving gear 41 and the front arc-shaped rack 22 can make the front transmission disc 21 swing back and forth. When the front transmission disc 21 swings back and forth, the rolling friction between the arc-shaped groove 211 and the guide roller 42 can make the sliding seat 37 slide back and forth along the support frame 2. When the sliding seat 37 slides back and forth up and down, the front contact roller 45 can move the toggle rod of the toggle button 46 back and forth up and down through the toggle pin 43 and the front compression spring 44, thereby adjusting the speed of the speed regulating motor 38. During the reciprocating swing of the front transmission disc 21, the guide roller 42 can intermittently press the transmission seat 23 downward and intermittently withdraw from the bottom of the arc-shaped groove 211. When the transmission seat 23 withdraws from the arc-shaped groove 211 and follows the swing of the front transmission disc 21, it can roll and rub with the rear contact roller 32 and press downward, so that the lower pressing seat 31 is self-resetting. When the button 34 is pressed down, the transmission seat 23 will not contact the rear contact roller 32 when it is not pressed downward by the guide roller 42. During the reciprocating swing of the front transmission plate 21, the upper pinion 8 and the hollow shaft 4 can rotate in the opposite direction of the swinging direction of the stirring tank 5 through the stirring tank 5, the rear arc-shaped rack 15, the lower pinion 17, the transmission shaft 16 and the large gear 18, thereby facilitating the discharge of objects in the stirring tank 5 and improving the stirring and mixing effect during the stirring process. During the rotation of the hollow shaft 4, the auxiliary scraper 11 is always in contact with the front and rear ends of the stirring tank 5. During the rotation of the hollow shaft 4, the main scraper 12 can contact the arc-shaped wall of the stirring tank 5. The narrower part of the main scraper 12 than the main support shaft 3 can contact the limiting column 10. When the narrower part of the main scraper 12 than the main support shaft 3 contacts the limiting column 10, the main scraper 12 can contact the arc-shaped wall of the stirring tank 5.

[0024] Working principle of the present invention: In order to facilitate the description of the movement process, the following descriptions of the rotation directions of "clockwise" and "counterclockwise" are all made from the main viewing angle.

[0025] When the narrower part of the main scraper 12 contacts the limit column 10, the main scraper 12 is in a counterclockwise eccentric setting compared to the hollow shaft 4, and the unloading barrel 35 receives the petrochemical product to be stirred. Initially, the guide plate 40 is at the bottom of the arc groove 211, and the toggle rod of the toggle button 46 is in a downward toggle state. At this time, the toggle button 46 controls the speed regulating motor 38 to be in a low-speed clockwise rotation state through the controller 47. The transmission seat 23 is pressed by the guide roller 42 to press the rear contact roller 32, and then the lower pressing seat 31 presses the self-reset button 34, so that the solenoid valve 36 can be opened, that is, the petrochemical product can fall into the stirring tank 5 at this time. As the speed regulating motor 38 rotates clockwise at a low speed, the driving gear 41 and the front arc The meshing of the arc-shaped rack 22 makes the front transmission disc 21, the stirring tank 5 and the rear transmission disc 14 rotate counterclockwise. During this process, the upper pinion 8 and the hollow shaft 4 are rotated clockwise at high speed through the rear transmission disc 14, the rear arc-shaped rack 15, the lower pinion 17, the transmission shaft 16 and the large gear 18, so that the petrochemical product can be stirred by the main scraper 12 and the stirring rod 7. During the stirring of the petrochemical product by the main scraper 12, due to the resistance of the petrochemical product, the wider part of the main scraper 12 is located at the rear of the movement direction, and the narrower part of the main scraper 12 is located at the front of the movement direction. Therefore, at this time, the main scraper 12 does not contact the limit column 10 and the arc-shaped wall of the stirring tank 5, and the guide bar 13 can The flow is guided to make the petrochemical products more fully mixed. When the guide roller 42 is released from the downward pressure on the transmission seat 23, the transmission seat 23 is extended from the bottom of the arc groove 211 under the elastic repulsive force of the rear compression spring 26. At this time, the transmission seat 23 is released from the contact with the rear contact roller 32. Therefore, the lower pressing seat 31 releases the pressure on the self-reset button 34 under the elastic repulsive force of the middle compression spring 33. At this time, the solenoid valve 36 is closed, that is, the petrochemical products stop falling. As the speed regulating motor 38 continues to rotate, the driving gear 41 passes through the leftmost part of the front arc-shaped rack 22 and enters the upper part. In this process, the stirring tank 5 rotates counterclockwise to the maximum state, thereby realizing the dumping of the petrochemical products. At the same time, the arc groove 211 and the guide roller 42 and The cooperation of the guide plate 40 will make the sliding seat 37 slide upward, so that the toggle pin 43, the front compression spring 44 and the front contact roller 45 can be used to toggle the toggle rod of the toggle button 46 upward, so that the speed regulating motor 38 can be controlled by the controller 47 to rotate at high speed. At this time, the guide plate 40 is at the upper part of the arc groove 211, and the driving gear 41 is meshed with the upper part of the front arc rack 22. Therefore, the stirring tank 5 will rotate counterclockwise at high speed. When the guide plate 40 turns to the lower part through the rightmost part of the arc groove 211, the stirring tank 5 is in a state of tilting to the right. During this process, the hollow shaft 4 is in a state of high-speed clockwise rotation, so that the auxiliary scraper 11 can be used to scrape the front and rear ends of the inner wall of the stirring tank 5 at high speed. At the same time,The main scraper 12 is blocked by the attachments attached to the arc-shaped wall of the mixing tank 5 and the limit column 10, and its own inertia will enable the main scraper 12 to maintain contact with the limit column 10, so that the attachments attached to the arc-shaped wall of the mixing tank 5 can be scraped off, and the scraped attachments can eventually follow the mixing tank 5 that is tilted to the right and fall out, thereby achieving the cleaning effect. As the guide plate 40 enters the lower part of the arc-shaped groove 211, the sliding seat 37 will slide downward, so that the toggle pin 43, the front compression spring 44 and the front contact roller 45 can be used to toggle the toggle rod of the toggle button 46 downward, so that the speed regulating motor 38 can be controlled by the controller 47 to enter low-speed rotation, and then the guide plate 40 uses the guide roller 42 to press the transmission seat 23 again, so that the solenoid valve 36 is opened again, and this cycle is repeated.

[0026] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
