Abstract
Description
Technical Field
[0001] The present application relates to the field of separation, and in particular to a fault monitoring device for a large tank rotary scraper at a joint station. Background Art
[0002] At present, most water injection stations in oilfield joint stations use rotary scraping and sludge removal devices for sludge removal. The rotary scraping and sludge removal device uses an external motor reducer to drive the scraping and suction arm through the transmission mechanism in the large tank to make slow circular motion around the central support seat. The lower scraper of the scraping and suction arm is used to scrape the sludge at the bottom of the tank. The suction plate installed on the suction pipe will scrape the scraped sludge to the suction nozzle during the rotation process. At the same time, the electric valve on the mud discharge pipe is automatically opened, and the sludge around the suction nozzle is sucked and discharged by the gravity difference of the liquid in the tank. The rotary scraping and sludge removal device has been widely used in joint stations because of its more thorough sludge removal and better effect.
[0003] However, if a large tank rotary scraper stops rotating due to a fault during use, it is difficult to detect and cannot be repaired in time, which will cause the mud discharge effect of the large station storage tank, buffer tank and water injection tank to deteriorate, affecting normal production operations. At the same time, since the large tank rotary scraper has a small current when running, the current change rate after a fault occurs is very small, and the use of current to monitor the fault is not effective.

[0027] The features and performance of the fault monitoring device for the large tank rotary scraper and desludging machine of the combined station of the present application are further described in detail below in conjunction with the embodiments.
[0028] Example 1
[0029] like Figure 1As shown, the embodiment of the present application provides a fault monitoring device for a rotary scraper and sludge remover of a large tank at a joint station, which is used to monitor a rotary scraper and sludge remover 110 installed in a tank body 100. The rotary scraper and sludge remover 110 includes a central support seat 130 connected to the center of the inner bottom wall of the tank body 100 and three scraping and suction mud arms 120 connected to the central support seat 130. When the rotary scraper and sludge remover 110 is working, the rotary scraper and sludge remover 110 rotates around the central support seat 130; the fault monitoring device for a rotary scraper and sludge remover of a large tank at a joint station includes an L-shaped test frame 200 installed on the inner wall of the tank body 100 and a pickup 300 installed on the outer wall of the tank body 100. One end of the test frame 200 is vertically arranged and connected to the inner wall of the tank body 100 by bolts. The other end of 200 is arranged horizontally and is connected to an elastic pick 210 at the same height as the scraping and suction mud arm 120. The elastic pick 210 extends from one end of the test frame 200 to the rotation path of the scraping and suction mud arm 120; when the scraping and suction mud arm 120 of the rotary scraper 110 rotates, it presses and pushes the elastic pick 210 to reset after deformation. The microphone 300 is used to collect the sound generated when the elastic pick 210 is deformed and reset. The microphone 300 is electrically connected to a display 310 through a data line. The display 310 is used to display the sound wave signal collected by the microphone 300. The microphone 300 is connected to a magnet 320 for adsorbing on the outer wall of the tank body 100. The magnet 320 is annular and fixedly mounted on the microphone 300.
[0030] The working principle of the fault monitoring device for the rotary scraper and sludge remover of a large tank provided in the embodiment of the present application is as follows: when the rotary scraper and sludge remover 110 in the tank body 100 is working normally, the scraper and sludge suction arm 120 makes a circular motion around the central support seat 130, and when the scraper and sludge suction arm 120 rotates, it will contact the elastic paddle 210 installed on the test frame 200 on the inner wall of the tank body 100, so that the scraper and sludge suction arm 120 periodically pushes the elastic paddle 210 to bend and deform, and then resets to generate a periodic sound signal, which is collected in real time by the microphone 300 adsorbed on the outer wall of the tank body 100. The elastic pick 210 generates a sound signal after being bent and deformed and reset, and the sound wave signal is displayed through the display 310 electrically connected to the pickup 300. The staff regularly checks the sound wave signal displayed on the display 310 to judge the working condition of the rotary scraper 110. When the rotary scraper 110 in the tank body 100 fails, the scraping and suction arm 120 stops rotating and pushes the elastic pick 210 to bend and deform, and the periodic sound signal will no longer appear, causing the sound signal output by the pickup 300 to change, so that the staff can promptly discover and judge the failure of the rotary scraper 110.
[0031] The microphone 300 is connected to a magnet 320 for adsorbing on the outer wall of the tank body 100, which can facilitate the operator to quickly and efficiently use the magnet 320 to adsorb on the tank body 100 and install the microphone 300 on the outer wall of the tank body 100 to collect sound signals inside the tank body 100; the magnet 320 is annular and is fixedly mounted on the microphone 300 to ensure that the microphone 300 is stably attached to the outer wall of the tank body 100 when adsorbed on the outer wall of the tank body 100.
[0032] Example 2
[0033] like Figure 2 and Figure 3 As shown, the embodiment of the present application provides a fault monitoring device for a large tank rotary scraper and sludge remover at a joint station. The structure of the fault monitoring device for a large tank rotary scraper and sludge remover at a joint station is substantially the same as that provided in Example 1. The difference is that, in this embodiment, the test frame 200 includes a fixed plate 220 connected to the inner wall of the tank body 100. The fixed plate 220 is provided with a slide groove 230 extending in the height direction and a slider 240 slidingly arranged in the slide groove 230. The slider 240 is threadedly connected to a fixing bolt 250. The fixing bolt 250 is configured to move axially to press or stop pressing the fixed plate 220 when rotating, so as to fix or release the slider 240 and the fixed plate 220. The slider 240 is connected to a fixing sleeve 260, and the fixing sleeve 260 is threadedly connected to a threaded rod 270. The elastic paddle 210 is connected to the threaded rod 270. When the threaded rod 270 rotates, it moves axially along the fixing sleeve 260 and radially along the tank body 100.
[0034] The test frame 200 in the fault monitoring device of the rotary scraper and sludge remover of the joint station provided in the embodiment of the present application includes a fixing plate 220 connected to the inner wall of the tank body 100 and a slide groove 230 provided on the fixing plate 220. The operator can move the slider 240 along the slide groove 230 to a preset position and then rotate the fixing bolt 250 to make the fixing bolt 250 move axially to press the fixing plate 220 to fix the slider 240 and the fixing plate 220, thereby adjusting the height of the slider 240 and the elastic paddle 210 connected thereto, and rotating the threaded rod 220 relative to the fixing sleeve 260 connected to the slider 240. 70, so that when the threaded rod 270 rotates, it moves along the axial direction of the fixed sleeve 260 and the radial direction of the tank body 100 to adjust the radial position of the elastic pick 210 connected to the threaded rod 270. After the fault monitoring device of the large tank rotary scraper and mud discharger of the joint station is installed in the tank body 100, the height and radial position of the elastic pick 210 can be adjusted quickly and efficiently, so that the elastic pick 210 is located on the movement trajectory of the scraping and suction mud arm 120 of the rotary scraper and mud discharger 110, ensuring that when the scraping and suction mud arm 120 rotates, it pushes the elastic pick 210 to bend and deform and then reset to generate a periodic sound signal for collection and monitoring.
[0035] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
