Description

Technical Field

[0001] The utility model relates to a light aggregate material processing technology, in particular to a ceramsite proppant impurity removal device. Background Art

[0002] Ceramic granule proppants are used as the main filler to prevent cracks from closing after pressure is removed and form oil and gas diversion channels during the collection of crude oil and natural gas. They can significantly increase the production of oil and gas wells and extend their production service life, so they are widely used in the oil and gas production process. Ceramic granule proppants have become an indispensable raw material for the exploitation of low-permeability oil and gas wells, but the tiny particles and micropowders attached to the surface of ceramsite proppants, when combined with organic materials in the fracturing fluid, can easily block the cracks formed by the proppants, reduce the production and service life of the oil and gas wells, and in severe cases, make the oil and gas wells scrapped. Therefore, impurity removal is one of the important processes for quality assurance of ceramsite proppants.

[0003] The existing production process of ceramsite proppants may cause tiny particles and powders to adhere to the surface of the product during granulation, semi-finished product screening, calcination, cooling, and finished product screening, resulting in poor product quality. Due to the low density of ceramsite, it floats on the surface of the cleaning agent during cleaning, and the salts and dust on the surface of the ceramsite proppants cannot be cleaned well, resulting in incomplete cleaning.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0023] like Figures 1 to 4In the embodiment of the ceramsite proppant impurity removal device of the utility model shown, the ceramsite proppant impurity removal device includes a cleaning box 1, a partition 2 is provided in the cleaning box 1, the partition 2 divides the cleaning box 1 into a sedimentation tank, a rotating roller fork 3 is provided above the sedimentation tank, an outflow port 4 is provided at one end of the cleaning box 1, a conveying mesh belt 5 is provided below the outflow port 4, a water collection box 6 is provided below the conveying mesh belt 5, and the water collection box 6 is connected to a pipe at the other end of the cleaning box 1.

[0024] Specifically, the ceramsite proppant to be removed is dropped into the cleaning box 1 along the conveying device, and the cleaning agent in the cleaning box 1 flows toward the outflow port 4. Due to the high density of the unripened ceramsite and the impurities with high density, they sink into the sedimentation tank in the cleaning agent. The ceramsite floating on the surface of the cleaning agent is fully mixed and cleaned with the cleaning agent under the action of the rotating roller fork 3. The ceramsite flows toward the outflow port 4 along with the flow of the cleaning agent, and falls onto the conveyor mesh belt 5 after flowing out of the outflow port 4. The cleaning agent and the cleaned floating foam and floating ash pass through the mesh of the conveyor mesh belt 5 to the water collecting box 6 to wait for filtration and reuse, and the cleaned ceramsite enters the next process.

[0025] In one embodiment of the present application, preferably, a plurality of raised anti-slip strips 7 are fixedly connected to the conveyor mesh belt 5 to prevent the expanded clay from slipping on the conveyor mesh belt 5 .

[0026] In one embodiment of the present application, preferably, a scraper 8 is provided under the conveyor mesh belt 5, and the scraper 8 contacts the conveyor mesh belt 5. The scraper 8 is fixedly connected to a crank 9, and the other end of the crank 9 is fixedly connected to a ball 10. The corner of the crank 9 is hinged on the water collecting box 6, and a filter screen 11 is fixedly installed on the top surface of the water collecting box 6. The ball 10 contacts the filter screen 11, and the cleaning agent and impurities fall from the mesh holes of the conveyor mesh belt 5 to the filter screen 11 on the water collecting box 6. The filter screen 11 filters out the impurities, and the scraper 8 scrapes off the impurities remaining on the mesh belt. When the anti-slip strip 7 of the conveyor mesh belt 5 moves to the scraper 8, the anti-slip strip 7 touches the scraper 8, so that the crank 9 rotates around the hinged support at the corner position, and the ball 10 is lifted. After the anti-slip strip 7 passes, the ball 10 falls again and knocks the filter screen 11, so that the filter screen 11 intermittently knocks and vibrates, thereby shaking off the impurities from the filter screen 11 to avoid the filtered impurities clogging the filter screen 11.

[0027] In one embodiment of the present application, preferably, the top surface of the water collecting box 6 and the filter screen 11 are tilted downward to facilitate knocking and vibrating impurities on the filter screen 11 to fall off.

[0028] In one embodiment of the present application, preferably, the roller fork 3 is in the same height as the outflow port 4, so that the roller fork 3 knocks the ceramsite into the cleaning agent, so that the cleaning agent can fully contact the entire surface of the ceramsite.

[0029] In one embodiment of the present application, preferably, the partition 2 is lower than the outflow port 4, so as to separate the ceramsite and impurities that sink with different densities and facilitate the ceramsite to flow with the cleaning agent in the cleaning agent.

[0030] In one embodiment of the present application, preferably, a water pump 12 is installed on the pipeline to reuse the filtered cleaning agent and provide a water pressure difference for the cleaning agent to flow in the cleaning tank 1 .

[0031] In one embodiment of the present application, preferably, the pipeline is provided with a plurality of evenly arranged branch pipes 13, and the branch pipes 13 are connected to the cleaning tank 1, so that the cleaning agent in the cleaning tank 1 flows evenly.

[0032] In one embodiment of the present application, preferably, a slag discharge port 14 is provided at the bottom of the sedimentation tank for cleaning the precipitated impurities and ceramsite out of the cleaning box 1 .

[0033] In one embodiment of the present application, preferably, a motor 15 for driving the roller fork 3 to rotate is provided on the cleaning box 1 . The motor 15 is used to drive the roller fork 3 to rotate.

[0034] In summary, the ceramsite proppant impurity removal device in the above embodiment of the utility model, specifically, drops the ceramsite proppant to be removed along the conveying device to the cleaning box 1, and the cleaning agent in the cleaning box 1 flows toward the outflow port 4. Since the unripened ceramsite has a large density and the impurities with large density sink downward into the sedimentation tank in the cleaning agent, the ceramsite floating on the surface of the cleaning agent is fully mixed and cleaned with the cleaning agent under the action of the rotating roller fork 3, and the ceramsite flows toward the outflow port 4 along with the flow of the cleaning agent, and falls onto the conveyor mesh belt 5 after flowing out of the outflow port 4. The cleaning agent and the cleaned floating foam and floating ash pass through the mesh holes of the conveyor mesh belt 5 and flow to the filter screen 11 on the water collection box 6. The filter screen 11 filters out the impurities, and the anti-slip strip 7 on the conveyor mesh belt 5 pushes the scraper 8 when the conveyor mesh belt 5 moves. The crank 9 drives the ball 10 to leave the filter screen 11. After the anti-slip strip 7 passes, the ball 10 falls back and knocks the filter screen 11, causing the filter screen 11 to vibrate, shaking off the impurities on the filter screen 11 to avoid clogging the filter screen 11. The filtered cleaning agent is recycled to the other end of the cleaning box 1 under the action of the water pump 12, and the cleaned ceramsite enters the next process. The device preliminarily removes impurities through the floating state of impurities and unripened ceramsite and ceramsite with different densities in water, and then uses the rotating roller fork to fully contact the ceramsite with the cleaning agent to clean the salt and floating dust on the surface of the ceramsite. After the cleaning is completed, the ceramsite and impurity cleaning agent mixture, impurities and cleaning agent are separated one by one through the conveyor belt and the filter screen, so that the ceramsite is fully and thoroughly cleaned, and the cleaning agent is filtered and reused to save resources.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
