Description

Technical Field

[0001] The utility model relates to the technical field of drilling auxiliary agent production, in particular to a material mixing device for producing oilfield drilling auxiliary agents. Background Art

[0002] Oil and gas field development is a complex and comprehensive project consisting of exploration, drilling, downhole operations, oil production, gathering and transportation. A large amount of chemicals are required in each operation. Drilling fluid, also known as drilling mud, is an important auxiliary material for geological exploration. Its functions are to break the core, carry cuttings, lubricate and cool the drill bit, balance the formation pressure and protect the well wall.

The technical solution disclosed in the patent document is as follows: it includes a mixing barrel, a motor, a balancing barrel, a cleaning shaft, a driven shaft, two sets of pulleys, a belt and a stirring shaft. A base is provided at the bottom end of the mixing barrel, and four sets of legs are provided at the bottom end of the base. A loading rack is provided at the top end of the mixing barrel, and a frame is provided at the right end of the mixing barrel. The motor is fixedly mounted on the frame, and a driving shaft is provided at the output end of the motor. The balancing barrel is rotatably mounted in the mixing barrel through the driving shaft. A loading cover and multiple sets of discharge ports are provided on the balancing barrel, and a top cover is provided at the top end of the mixing barrel. The cleaning shaft is rotatably mounted in the mixing barrel, and multiple sets of brushes are provided on the cleaning shaft.

[0022] See also Figure 1-5The utility model provides a technical solution: comprising a mixing barrel 1 and a blanking barrel 2, the mixing barrel 1 and the blanking barrel 2 are both arranged in a cylindrical structure, the bottom of which is a funnel-shaped slope structure, the inclined state is more convenient for the raw materials to fall, the lower end of the mixing barrel 1 is welded with one end of the funnel structure and one end of the cylindrical structure of the blanking barrel 2, and the mixing barrel 1 and the blanking barrel 2 are in a mutually penetrating state, two circular holes on the same horizontal line are opened on the top of the mixing barrel 1, and a funnel-shaped first feeding port 5 and a second feeding port 6 are welded at the position of the circular holes, and the purpose of opening the two ports is to allow a variety of raw materials to The raw materials are poured into the mixing barrel 1 at the same time, which avoids the situation that the raw materials are poured in batches and uneven mixing occurs. A mixing assembly 3 is provided inside the mixing barrel 1 and the blanking barrel 2. The mixing assembly 3 includes a rotating shaft 301. The rotating shaft 301 extends from the top of the mixing barrel 1 to the inside of the blanking barrel 2, and the end of the rotating shaft 301 located inside the mixing barrel 1 extends to the outside of the mixing barrel 1, and the end extending to the outside is welded to the output end of the first driving motor 302.

There are five mixing rollers 303 in a row, and And it is composed of four rows of mixing rollers 303. A large number of mixing rollers 303 can achieve the purpose of quickly and evenly mixing the raw materials. One end of the rotating shaft 301 inside the blanking barrel 2 is welded with a throwing box 304. The throwing box 304 is a cylindrical structure as a whole, and a funnel-shaped baffle is also arranged on the top. The baffle is located directly below the circular hole connected between the mixing barrel 1 and the blanking barrel 2. The first mixed raw materials in the mixing barrel 1 fall into the throwing box 304 through the circular hole. Because of the funnel-shaped baffle on the top of the throwing box 304, the raw materials can fall into the throwing box 304 completely. A plurality of ejection ports 305 are evenly provided on the side of the ejection box 304. The ejection ports 305 are arranged in a rectangular structure. The raw materials entering the ejection box 304 are subjected to secondary mixing by centrifugal force. The uniformly mixed raw materials are ejected from the ejection ports 305 and fall into the blanking barrel 2. A discharge port 8 is provided at the bottom of the blanking barrel 2. The secondary uniformly mixed raw materials are discharged through the discharge port 8. A base frame 7 is welded at the bottom of the blanking barrel 2. After the base frame 7 falls to the ground, the discharge port 8 can be normally arranged in the air, and will not affect the normal discharge of the mixed raw materials.

[0023] A cleaning assembly 4 is provided inside the blanking barrel 2, and the cleaning assembly 4 includes a screw rod 401 and a slide rod 402. A first bottom plate 403 and a second bottom plate 404 are welded to the inner wall of the blanking barrel 2. The first bottom plate 403 and the second bottom plate 404 are arranged in the same horizontal plane. Both ends of the screw rod 401 are fixed to the first bottom plate 403 and the inner wall of the blanking barrel 2 through bearings. One end of the screw rod 401 connected to the blanking barrel 2 extends to the outside of the blanking barrel 2 and is welded to the output end of the second drive motor 407. Both ends of the slide rod 402 are welded to the second bottom plate 404 and the inner wall of the blanking barrel 2, respectively. A first slider 405 is provided, and the first slider 405 moves up and down on the surface of the screw rod 401 through an internal threaded structure. A second slider 406 is provided on the surface of the slide bar 402, and the second slider 406 can slide freely up and down on the slide bar 402. Scrapers 408 are adhered to the surfaces of the first slider 405 and the second slider 406. Two scrapers 408 are provided, and the two scrapers 408 are arc structures. The outer surface of the scraper 408 is in contact with the inner wall of the blanking barrel 2. The scraper 408 is made of silicone structure, which can scrape off the raw material attached to the inner wall of the blanking barrel 2 without damaging the inner wall of the blanking barrel 2.

[0024] Working principle: When in use, the utility model drives the mixing roller 303 and the throwing box 304 to rotate through the rotating shaft 301 to achieve the mixing effect on the raw materials. First, start the first drive motor 302. Under the drive of the first drive motor 302, the rotating shaft 301 drives the mixing roller 303 and the throwing box 304 to rotate simultaneously, and then pour a variety of raw materials into the mixing barrel 1 through the first feed port 5 and the second feed port 6 at the same time. Under the action of the mixing roller 303, the raw materials are preliminarily mixed, and the mixed raw materials fall from the mixing barrel 1 into the throwing box 304. Under the centrifugal force of the rotation of the throwing box 304, the preliminarily mixed raw materials rotate in the throwing box 304 for secondary mixing, and are thrown out through the throwing port 305. The thrown raw materials fall into the blanking barrel 2, and The raw materials are discharged through the discharge port 8. Because the raw materials are thrown out, they are attached to the blanking barrel 2. When there are more raw materials attached to the inner wall of the blanking barrel 2, the second drive motor 407 is started. Under the action of the second drive motor 407, the screw rod 401 starts to rotate, driving the first slider 405 to start rotating, and then driving the scraper 408 to move up and down. Because the second slider 406 is fixed to the other end of the scraper 408, the second slider 406 moves up and down on the slide bar 402 with the first slider 405, and the scraper 408 scrapes the raw materials attached to the inner wall of the blanking barrel 2, and the scraped raw materials are discharged through the discharge port 8.
