Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slag scraping devices, and in particular to a rotary slag scraping device for a mechanical slag scraping trough for coking plant tar and ammonia water. Background Technology
[0002] Tar ammonia water is a mixed liquid containing organic substances such as phenol, phenolic acid, and phenolic aldehyde.
[0003] The working principle of the tar-ammonia water scraping tank is mainly based on physical separation technology, separating tar residue from the tar-ammonia water mixture through mechanical scraping. Existing scraping devices use chain-driven scraper plates to remove floating scum from the tar-ammonia water scraping tank. The scraper plates are driven by the chain to circulate and scrape the scum. However, in existing technologies, the scraper plates cannot be cleaned during operation, and floating scum easily remains on them during the circulating scraping process, affecting the scum removal efficiency. To overcome the shortcomings of the above-mentioned technologies, we propose a rotary scraping device for a mechanical tar-ammonia water scraping tank in coking plants. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by proposing a rotary scraping device for a mechanical scraping trough for coking plant tar and ammonia water.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rotary scraping device for a mechanical scraping trough for coking plant tar and ammonia water includes a tar and ammonia water scraping trough. A cleaning component is provided on the right side of the tar and ammonia water scraping trough. The cleaning component includes two symmetrically arranged support seats. A drain pipe and a water inlet pipe are fixedly installed between the two support seats. Both the drain pipe and the water inlet pipe pass through to the back of the rear support seat. A water injection pipe is connected to the rear end of the drain pipe and the water inlet pipe. Water spray pipes are installed at equal intervals on both the drain pipe and the water inlet pipe. A photosensitive screen is screwed to the inner side of the front support seat. A mounting seat is screwed to the inner side of the rear support seat. An infrared laser emitting tube is fixedly installed on the side of the mounting seat. A controller is fixedly installed on the outer wall of the front support seat.
[0007] Furthermore, the water spray pipe is installed at an angle.
[0008] Furthermore, a solenoid valve is fixedly installed on the water injection pipe, and a high-pressure water pump is connected to the lower end of the water injection pipe.
[0009] Furthermore, symmetrical support side plates are fixedly installed on both sides of the tar ammonia scraping trough. Two rotating shafts are rotatably installed on the inner side of the support side plates. Gears are fixedly installed on both rotating shafts. A chain is meshed on the outer side of the gears. A scraping assembly is installed on the chain. Arc-edge plates are symmetrically installed on both sides of the tar ammonia scraping trough.
[0010] Furthermore, the slag scraping assembly includes a slag scraping plate, and locking seats are symmetrically fixedly installed on both sides of the slag scraping plate, the locking seats being locked onto the outside of the chain.
[0011] Furthermore, an abutment screw is screwed onto the side of the snap-fit seat, and the inner end of the abutment screw is screwed through to the inside of the snap-fit seat.
[0012] Furthermore, a light-shielding plate is fixedly installed on the side of the scraper.
[0013] Furthermore, a drive motor is fixedly installed on the outer wall of the support side plate, and the output end of the drive motor passes through to the inner side of the support side plate and is fixedly connected to the rotating shaft on the left side.
[0014] Compared with related technologies, the rotary scraping device for a mechanical scraping trough for coking plant tar and ammonia water proposed in this utility model has the following beneficial effects:
[0015] In this invention, a rotary scraping device for a mechanical scraping trough for coking plant tar and ammonia water is described. Through a cleaning component, when the scraper plate is driven to the right side of the tar and ammonia water scraping trough, it blocks the laser emission path of the infrared laser emitting tube in the cleaning component, preventing the corresponding photosensitive screen from sensing the laser source. At this point, the controller, based on the photosensitive data on the screen, determines that the scraper plate is inside the cleaning zone and quickly opens the solenoid valve. This causes the water spray pipes evenly distributed on the upper and lower water pipes to simultaneously spray water onto the upper and lower sides of the scraper plate for cleaning. This ensures that the scraper plate is cleaned during each scraping cycle, preventing residual scum from being carried back into the tar and ammonia water scraping trough, thus improving scraping efficiency and enhancing practicality.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Reference Figure 1-5 A rotary scraping device for a mechanical scraping trough for tar and ammonia water in a coking plant: including a tar and ammonia water scraping trough 1, with a cleaning component 9 on the right side of the tar and ammonia water scraping trough 1; the cleaning component 9 includes two symmetrically arranged support seats 91, with a drain pipe 96 and an upper water pipe 97 fixedly installed between the two support seats 91, both the drain pipe 96 and the upper water pipe 97 passing through to the back of the rear support seat 91, and a water injection pipe 99 connected to the rear ends of the drain pipe 96 and the upper water pipe 97, with water spray pipes 98 installed at equal intervals on both the drain pipe 96 and the upper water pipe 97, a photosensitive screen 95 screwed to the inside of the front support seat 91, an installation seat 93 screwed to the inside of the rear support seat 91, an infrared laser emitting tube 94 fixedly installed on the side of the installation seat 93, a controller 92 fixedly installed on the outer wall of the front support seat 91, a solenoid valve 911 fixedly installed on the water injection pipe 99, and a high-pressure water pump 910 connected to the lower end of the water injection pipe 99.
[0024] In this configuration, the water spray pipe 98 is set at an angle.
[0025] With the above configuration, the water spray pipe 98 on the upper water pipe 97 is tilted downwards, while the water spray pipe 98 on the lower water pipe 96 is tilted upwards. When the scraper plate 71 rotates between the upper water pipe and the lower water pipe 96, the water spray pipes 98 on the upper water pipe 97 and the lower water pipe 96 can simultaneously rinse the upper and lower sides of the scraper plate 71, thereby enabling the scraper plate 71 to be cleaned without dead angles.
[0026] In this method, symmetrical support side plates 2 are fixedly installed on both sides of the tar ammonia scraping trough 1. Two rotating shafts 3 are rotatably installed on the inner side of the support side plates 2. Gears 4 are fixedly installed on both rotating shafts 3. Chains 5 are meshed on the outer side of the gears 4. Scraping components 7 are installed on the chains 5. Arc-edge plates 8 are symmetrically installed on both sides of the tar ammonia scraping trough 1.
[0027] By setting the arc-edge plate 8 as described above, the tar ammonia scraper trough 1 has an arc-edge guiding function, which prevents the scraper plate 71 from getting stuck and scraping when passing through both sides of the tar ammonia scraper trough 1.
[0028] In this method, the slag scraping assembly 7 includes a slag scraping plate 71, and symmetrically fixedly installed on both sides of the slag scraping plate 71 are locking seats 72. The locking seats 72 are locked onto the outside of the chain 5. An abutment screw 73 is screwed onto the side of the locking seat 72, and the inner end of the abutment screw 73 is screwed through to the inside of the locking seat 72.
[0029] By setting it up in the above manner, the two locking seats 72 on both sides of the locking seat 72 are respectively locked onto the outside of the chain 5. At this time, tighten the abutment screw 73 so that the inner end of the abutment screw 73 abuts against the side of the chain 5, so that the locking seat 72 and the chain 5 are effectively fixed, thereby completing the installation and positioning of the scraper plate 71 on the chain 5.
[0030] In this method, a light-shielding plate 74 is fixedly installed on the side of the slag scraper 71.
[0031] With the above-described configuration, the light-shielding plate 74 is designed so that when the scraper plate 71 rotates and passes between the water inlet pipe 97 and the water outlet pipe 96, the light-shielding plate 74 can block the laser emitted by the infrared laser emitting tube 94.
[0032] In this method, a drive motor 6 is fixedly installed on the outer wall of the support side plate 2, and the output end of the drive motor 6 passes through to the inner side of the support side plate 2 and is fixedly connected to the left rotating shaft 3.
[0033] With the above configuration, the drive motor 6 can drive the left rotating shaft 3 to rotate, which in turn drives the chain 5 to rotate through the gear 4, synchronously driving the right rotating shaft 3 to rotate, so that the scraper plate 71 installed on the chain 5 can rotate synchronously with the chain 5.
[0034] The working principle of the rotary scraping device for a mechanical scraping trough for coking plant tar and ammonia water provided by this utility model is as follows:
[0035] In use, the drive motor 6 is started, driving the rotating shaft 3 to rotate. The gear 4 on the rotating shaft 3 drives the chain 5 to rotate on the upper side of the tar ammonia scraping trough 1, which in turn drives the scraper plate 71 installed on the chain 5 to rotate. As the scraper plate 71 moves to the right side of the tar ammonia scraping trough 1 with the chain 5, it scrapes the floating scum on the upper side of the tar ammonia scraping trough 1 to the right side. When it passes the arc edge plate 8 on the right side of the tar ammonia scraping trough 1, it scrapes the floating scum to the outside of the tar ammonia scraping trough 1. Subsequently, when the scraper plate 71 rotates between the water inlet pipe 97 and the water outlet pipe 96, the light shield 74 on the side of the scraper plate 71 will block the laser emitted by the infrared laser emitting tube 94, thus preventing the laser from reaching the target area. When the laser source is not detected on the photosensitive screen 95, the controller 92, based on the photosensitive data on the photosensitive screen 95, knows that the scraper 71 is inside the cleaning zone. It quickly turns on the high-pressure water pump 910 and the solenoid valve 911, so that the water spray pipes 98 evenly installed on the water inlet pipe 97 and the water outlet pipe 96 simultaneously spray water onto the upper and lower sides of the scraper 71 for cleaning. This ensures that the scraper is cleaned once during each scraping cycle, preventing the scraper from carrying residual scum back into the tar ammonia water scraping tank. When the scraper 71 passes between the water inlet pipe 97 and the water outlet pipe 96, the high-pressure water pump 910 and the solenoid valve 911 quickly shut off to avoid wasting water.
[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
