Description

Technical Field

[0001] The utility model belongs to the technical field of oily sludge treatment equipment, in particular to an oily sludge-water separation device with a cleaning function. Background Art

[0002] Oily sludge is an emulsion of various oils, water, ash and residues. It is produced by various industrial and civil activities related to crude oil and refined oil, such as oil field exploitation, oil refining process, transportation, use, storage, etc. Because it contains many chemicals, it is tightly contained together. The higher the temperature, the tighter the containment. The traditional method of extracting crude oil from oily sludge is to add an emulsifier, stir and heat it, and then centrifuge it to separate the oil, and then separate the remaining mud. However, the mud still contains crude oil and some metal substances, and it cannot be directly dumped and buried to avoid environmental pollution and waste of resources. Therefore, the remaining mud needs to be separated from the water first and then dehydrated. However, when separating the mud and water, a flocculant needs to be added, and the mud needs to sink to the bottom of the device, and then the upper water is extracted for the next step of treatment. After the existing device separates the water, the mud at the bottom of the device is easily adsorbed on the inner wall of the device and is not easy to remove. It needs to be shut down and manually cleaned, resulting in low production efficiency. Therefore, it is necessary to design a device that can scrape the mud attached to the inner wall of the device from east to west, clean the mud at the bottom of the device in time, reduce manual labor intensity, and improve production efficiency. Utility Model Content

[0003] In response to the above technical problems, the utility model provides a device that can scrape mud attached to the inner wall of the device from east to west, reduce labor intensity, and improve production efficiency, so as to solve the problem that mud is adsorbed on the inner wall of the device and is difficult to remove during the mud-water separation process.

[0004] The cam is provided with a support frame, and the bottom end of the support frame is fixedly connected to the support frame, and the transmission gear is provided with a transmission gear on the inside of the support frame.

[0005] Furthermore, the top of the separation tank is fixedly connected to a support platform via a bracket, a second motor is fixedly connected to the support platform, and an output end of the second motor is fixedly connected to the transmission shaft.

[0006] Furthermore, a filter screen is provided in the water filter port.

[0007] Furthermore, the first stirring shaft, the second stirring shaft and the transmission shaft are horizontally fixedly connected, and the first stirring shaft is located above the second stirring shaft.

[0008] Furthermore, a protruding block is fixedly connected to one side of the base relative to the transmission shaft, and the sides of the protruding block and the damper located on the same horizontal plane are both inclined surfaces, and the inclined surfaces of the protruding block and the damper on both sides are in opposite directions.

[0009] Furthermore, the slide rail and the slider are both located in the sealing layer, the upper and lower ends of the connecting rod pass through the sealing layer, and the connecting rod is slidably connected to the sealing layer.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. The utility model provides a stirring shaft in the separation tank, which can stir the mud-water mixture after mixing with the flocculant, thereby accelerating the mud flocculation speed and improving the production efficiency of the device; by arranging a scraper at the bottom of the separation tank, the mud attached to the bottom of the inner wall of the device can be cleaned by the rotation of the scraper, thereby accelerating the mud recovery speed and improving the production efficiency; by installing a damper on the first stirring shaft and a spring sleeve on the damper, the first stirring shaft will not drive the scraper to rotate when rotating, thereby achieving a cleaning effect; by arranging a sealing layer on the inner wall of the separation tank, the mud will not enter the slide rail, causing the slide rail to be blocked, thereby improving the service life of the device.

[0012] 2. The utility model is fixedly connected to a support platform on the top of the separation tank through a bracket, and a second motor can be fixedly connected to the support platform. The second motor provides power for the transmission shaft. By arranging a filter screen in the water filter outlet, the remaining water in the mud and sand can be discharged from the bottom of the auger conveyor for secondary separation. By fixing a base at the upper end of the connecting rod and arranging raised blocks in opposite directions on the base, it can be ensured that the first stirring shaft will not drive the scraper to rotate when it rotates counterclockwise, but only plays a role in stirring the mud and water, thereby accelerating the uniform mixing of the mud and water and the flocculant. When the first stirring shaft rotates clockwise, the raised block will be against one end of the damper, thereby driving the bottom scraper to clean the bottom of the device.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4The oily sludge-water separation device with a cleaning function shown in the figure includes a separation tank 1, a support frame 20 is fixedly connected to the bottom of the separation tank 1, in order to speed up the mixing speed when the mud and water are mixed with the flocculant, a transmission shaft 4 is provided inside the separation tank 1, and a first stirring shaft 5 and two second stirring shafts 10 are fixedly connected on both sides of the transmission shaft 4 in sequence. In order to achieve the purpose of the cleaning device, a damper 7 is fixedly connected to the other end of the first stirring shaft 5, a spring 6 is sleeved on the damper 7, and the other end of the damper 7 is set to a trapezoidal structure, and the longer trapezoidal surfaces on both sides are in opposite directions. When the first stirring shaft 5 rotates counterclockwise, it can rotate smoothly under the combined action of the damper 7 and the spring 6, thereby not driving the bottom scraper 14 to rotate. In order to enable the scraper 14 to rotate along the inner wall of the separation tank 1, two slide rails 11 are fixedly connected to the upper and lower sides of the inner wall of the separation tank 1. In order to ensure that the connecting rod 9 can follow the first stirring shaft 5 stably Fixed rotation, a slider 12 is symmetrically connected for sliding movement on both sides of each slide rail 11, and a connecting rod 9 is fixedly connected to the slider 12 on the same side to ensure that the connecting rod 9 does not shake. In order to enable the first stirring shaft 5 to drive the connecting rod 9 to rotate, a holder 8 is fixedly connected to the top of the connecting rod 9 and a scraper 14 is fixedly connected to the bottom. The scraper 14 can clean the mud on the bottom wall of the separation tank 1 to speed up production efficiency. The holder 8 and the damper 7 are located at the same horizontal plane. In order to facilitate the collection of mud after separation of water, a discharge port 15 is provided at the bottom of the separation tank 1. The bottom of the discharge port 15 is detachably connected to a screw conveyor 17, and the input end of the screw conveyor 17 is fixedly connected to a first motor 18. In order to filter out the residual water in the mud again, a water filter port 16 is provided at the bottom of the dragon conveyor 17. When the mud enters the dragon conveyor 17 from the discharge port 15, the mud is transported to the next link, and the residual water flows out from the water filter port 16 below.

[0020] In order to facilitate the entry of mud and water and the installation of the second motor, a support platform 3 is fixedly connected to the top of the separation tank 1 through a bracket 21, and a second motor 2 is fixedly connected to the support platform 3. The output end of the second motor 2 is fixedly connected to the transmission shaft 4.

[0021] In order to filter out the remaining water in the mud again and ensure that the mud does not flow out of the water filter port 16 , a filter screen 19 is provided in the water filter port 16 .

[0022] In order to ensure that the stirring of muddy water and the driving of the scraper for cleaning do not interfere with each other, the first stirring shaft 5 and the second stirring shaft 10 are fixedly connected to the transmission shaft 4 horizontally, and the first stirring shaft 5 is located above the second stirring shaft 10.

[0023] In order to ensure that one end of the damper 7 can be tightly connected to the protruding block 81 when the first stirring shaft 5 rotates clockwise, the bracket 8 is fixedly connected to the side of the transmission shaft 4 with the protruding block 81. The sides of the protruding block 81 and the damper 7 that are located on the same horizontal plane are both inclined, and the protruding blocks 81 on both sides are opposite to the inclined surfaces of the damper 7. Therefore, when the first stirring shaft 5 rotates clockwise, it can contact the non-inclined side of the damper 7 through the protruding block 81, thereby driving the scraper 14 to rotate and clean the device.

[0024] In order to ensure that mud does not enter the slide rail and damage the device, the slide rail 11 and the slider 12 are both located in the sealing layer 13, the upper and lower ends of the connecting rod 9 pass through the sealing layer 13, and the connecting rod 9 is slidably connected to the sealing layer 13.

[0025] The specific working process of this utility model is as follows:

[0026] After the oily sludge is initially separated and the oil is removed, the remaining mud-water mixture is poured into the gap between the separation tank 1 and the bracket 21. Then, a proportional flocculant is poured into the separation tank 1, and the second motor 2 is turned on to start counterclockwise rotation, driving the two second stirring shafts 10 below to start rotating and stirring. After stirring for a certain period of time, the second motor 2 is stopped and left to stand for a period of time. After the mud has all sunk to the bottom of the separation tank 1, a water pump is placed from the top to extract the water above and send it to the next link. When the water is pumped close to the mud, it stops. At this time, the discharge port 15 is opened, and the first motor 18 is turned on to drive the auger conveyor 17 to rotate, sending most of the mud out. Finally, the second motor 2 is turned on to slowly reverse. After rotating 180 degrees, one end of the damper 7 on both sides is connected to the protruding block 81, which pushes the card seat 8 to rotate through friction, and at the same time drives the bottom scraper 14 to start rotating to clean the bottom. Mud and water separation according to the above method can increase the mud collection speed, increase production rate, and reduce manual labor intensity.
