Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene production, in particular to a purging device. Background Art

[0002] With the continuous increase in the world's demand for petrochemical products, petrochemical plants and refineries have repeatedly expanded production, and the scale of by-product propylene has also increased accordingly. In this case, each petrochemical plant has carried out expansion and transformation of polypropylene production devices or built new polypropylene production lines; in the prior art, polyacrylamide first forms a polyacrylamide solution during the production process, and its surface is prone to film formation, which affects the quality of the polyacrylamide solution and also affects the subsequent treatment of polyacrylamide.

[0003] In the prior art, a purging device in a polypropylene production system is mentioned in the patent number (CN202123408238.2). When using this utility model, the polyacrylamide solution can be first sent into the main cylinder through the liquid inlet pipe, and at this time, the toothed scraper moves to the leftmost end of the main cylinder. When the solution is full, the blower is turned on, and the gas blown by the blower can disperse the polyacrylamide forming a film on the upper surface of the solution and make it move to the right. The positive and negative rotation motor is started to control the screw to rotate and drive the toothed scraper to scrape the film on the surface of the polyacrylamide to the right, and finally make it flow out of the main cylinder through the drain port. At the same time, the gas blown by the blower can keep the liquid surface in an unstable state all the time, which can prevent it from forming a film again. Some impurities will be doped in the polyacrylamide during the production process. An electromagnetic device is added, and the electromagnetic device is turned on during the purging process to adsorb the iron impurities in the polyacrylamide.

[0004] In the prior art, a blower, a control screw and a scraper are added, which effectively solve the problem that in the prior art, polyacrylamide first forms a polyacrylamide solution during the production process, and its surface is prone to film formation, which affects the quality of the polyacrylamide solution and also affects the subsequent treatment of polyacrylamide. However, due to the overly complex overall structure and the need to separately extract the polyacrylamide solution for the purging process, the production time of the polyacrylamide solution will be greatly delayed, and the production efficiency will be slowed down to a great extent. For this reason, we propose a purging device that can be installed on a polypropylene production line. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a purging device, which solves the problem that due to the overly complex overall structure and the need to separately extract the polyacrylamide solution for the purging process, the production time of the polyacrylamide solution will be greatly delayed, and the production efficiency will be slowed down to a great extent.

Figure 2 , which is a side view of the whole of the first embodiment of the present utility model. Figure 3 , which is a bottom view of the whole of the second embodiment of the present utility model.

[0022] The present utility model provides a purging device, including a sliding seat 101 and a sliding and swinging scraping assembly. The sliding and swinging scraping assembly includes a mounting groove 102, a sliding groove 103, a telescopic column 104, a placement plate 105, an air outlet 106, an air box 107, a telescopic pipe 108, a connecting plate 109, a rotating rod 110, a counterweight 111, a counterweight groove 114, a scraper 112 and an auxiliary plate 113. Through the foregoing solution, the problem that the overall structure is too complex and the polyacrylamide solution needs to be separately taken out for the purging process, which will greatly delay the production time of the polyacrylamide solution and slow down the production efficiency to a great extent, is solved. It can be understood that the foregoing solution can be installed on the production line for producing polyacrylamide solution when the polyacrylamide solution is stationary to prevent the formation of a film on the surface of the polyacrylamide solution. Then, the whole is installed at a specified position by using the mounting groove 102, and then the sliding seat 101 is slid by using the sliding groove 103. During the sliding process, the counterweight 111 will move in the opposite direction along with inertia, which will drive the rotating rod 110. The rotating rod 110 will drive the scraper 112 and the auxiliary plate 113 to scrape the surface of the polyacrylamide solution. At the same time, the air box 107 is started to blow high-pressure gas through the air outlet 106, thereby forming waves on the surface of the polyacrylamide solution to prevent secondary film formation. Thus, while retaining the original beneficial effects, the problem that the overall structure is too complex and the polyacrylamide solution needs to be separately taken out for the purging process, which will greatly delay the production time of the polyacrylamide solution and slow down the production efficiency to a great extent, is actively and effectively solved.

[0023] For this specific embodiment, the installation groove 102 is fixedly connected to the sliding seat 101 and is located below the interior of the sliding seat 101. The sliding groove 103 is fixedly connected to the sliding seat 101 and is located inside the sliding seat 101, and the sliding groove 103 is arranged on one side of the installation groove 102. The telescopic column 104 is detachably connected to the sliding seat 101 and is located above the sliding seat 101. The placement disc 105 is detachably connected to the telescopic column 104 and is located above the telescopic column 104. The air outlet 106 is detachably connected to the placement disc 105 and is located on one side inside the placement disc 105. The sliding seat 101 is the main functional component for installing the whole and sliding and swaying the counterweight 111 in cooperation with the slide rail on the production line, and the telescopic column 104 is the functional component for adjusting the specific height positions of the placement disc 105 and the connection disc 109, and the air outlet 106 is the auxiliary component for ejecting the high-pressure gas in the air box 107 through the telescopic tube 108.

[0024] Among them, the air box 107 is detachably connected to the sliding seat 101 and is located on one side of the sliding seat 101. One end of the telescopic tube 108 is detachably connected to the air box 107 and is located above the air box 107. The other end of the telescopic tube 108 passes through the placement disc 105 and is detachably connected to the air outlet 106 and is located at one end of the air outlet 106. The air box 107 is a place for storing high-pressure gas, and the telescopic tube 108 is a channel for transmitting high-pressure gas.

[0025] Secondly, the connection disc 109 is detachably connected to the placement disc 105 and is located above the placement disc 105. The rotating rod 110 is rotatably connected to the connection disc 109 and is located on one side of the connection disc 109. The connection disc 109 is a component for connecting the rotating rod 110, and the rotating rod 110 is an auxiliary functional component for rotating and swaying in cooperation with the counterweight 111 following inertia.

[0026] At the same time, the counterweight 111 is detachably connected to the rotating rod 110 and is located above the rotating rod 110. The counterweight groove 114 is detachably connected to the counterweight 111 and is located inside the counterweight 111. The counterweight 111 is a functional component for swaying using inertia. When the staff adds an appropriate amount of heavy objects to the counterweight groove 114, the amplitude of the swaying of the counterweight 111 can be effectively controlled.

[0027] In addition, the scraping plate 112 is detachably connected to the rotating rod 110 and is located below the rotating rod 110. The auxiliary plate 113 is detachably connected to the rotating rod 110 and is located below the rotating rod 110. The auxiliary plate 113 is disposed on one side of the scraping plate 112. The scraping plate 112 and the auxiliary plate 113 cooperate with each other to form a functional component for scraping the surface of the polyacrylamide solution when the rotating rod 110 rotates left and right.

[0028] When using the present utility model to produce polyacrylamide solution, in order to prevent the surface of the polyacrylamide solution from forming a film when the polyacrylamide solution is stationary, the whole is installed on the production line for producing polyacrylamide solution, and then the whole is installed at a specified position by using the installation groove 102. Then, the sliding seat 101 is slid by using the sliding groove 103. During the sliding process, the counterweight 111 will move in the opposite direction along with inertia, thereby driving the rotating rod 110. The rotating rod 110 drives the scraping plate 112 and the auxiliary plate 113 to scrape the surface of the polyacrylamide solution. At the same time, the air box 107 is started to blow high-pressure gas through the air outlet 106, thereby forming waves on the surface of the polyacrylamide solution to prevent secondary film formation. Thus, while retaining the original beneficial effects, it actively and effectively solves the problem that the overall structure is too complex, and it is necessary to separately take out the polyacrylamide solution for the purging process, which will greatly delay the production time of the polyacrylamide solution and slow down the production efficiency to a great extent.
