Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum adding devices, in particular to a phosphogypsum adding device for preparing special cement. Background Art

[0002] With the increasing scarcity of medium and high-grade gypsum resources, the use of industrial by-product gypsum as cement retarder has become the main choice of cement companies. Currently, the most widely used industrial waste gypsum is phosphogypsum. my country has a large amount of phosphogypsum emissions and a large stock. The mountains of phosphogypsum not only occupy land, but also cause serious pollution to the surrounding soil, air and water resources. The country attaches great importance to the treatment of phosphogypsum, and one of the ways to use it is to promote the resource utilization of industrial re-production gypsum such as phosphogypsum to replace natural gypsum.

[0003] Chinese utility model patent: Publication number CN212170865U discloses a phosphogypsum adding device for cement production, including a base, a stirring tank is arranged inside the base, and the two sides of the stirring tank are rotatably connected to the base, a tank cover is arranged on the top of the stirring tank, and the rear end of the tank cover is rotatably connected to the rear end of the top of the stirring tank, and a transfer chamber is opened in the middle of the tank cover, a feed port is arranged on the upper right side of the tank cover, and a discharge port is arranged on the lower left side of the tank cover, and the feed port and the discharge port are both connected to the transfer chamber, a second motor is arranged on the top of the tank cover, and the lower end of the second motor penetrates the box cover and is connected to the push plate, and the push plate is arranged inside the transfer chamber, a third motor is arranged at the bottom of the stirring tank, and the third motor penetrates the stirring tank and is connected to the stirring blade, and the stirring blade is arranged inside the stirring tank, a hydraulic device is arranged on the left and right sides of the bottom of the stirring tank, and the top of the hydraulic device is slidably connected to the T-slot, a scraper is arranged on the lower side of the stirring tank, and the scraper is arranged on the outside of the stirring blade, and a T-slot is opened at the bottom of the scraper.

[0004] In the prior art, CN212170865U is provided with a transfer chamber and a push plate when in use. Cement and phosphogypsum enter the interior of the transfer chamber through the feed port, and the second motor drives the push plate to rotate. The push plate pushes the cement and phosphogypsum to rotate inside the transfer chamber until the cement and phosphogypsum enter the interior of the mixing tank through the discharge port. The three push plates separate the feed port and the discharge port to prevent the dust in the mixing tank from being dispersed to the outside world, thereby protecting the health of the operator; a stirring blade and a scraper are provided. After the cement and phosphogypsum are mixed into concrete, the tank cover is opened by rotating. The first motor drives the mixing tank to rotate through a chain until the mixing tank flips over and pours out the concrete. The hydraulic device drives the scraper to move along the inner wall of the mixing tank. The scraper pushes the concrete adhered to the surface of the mixing tank and the surface of the stirring blade to leave the interior of the mixing tank, thereby reducing the difficulty of cleaning the mixing tank. However, when discharging, the phosphogypsum has a high water content and is easy to agglomerate and clog at the discharge port. Therefore, a phosphogypsum adding device for preparing special cement is needed to solve the above problems. Utility Model Content

[0019] By embedding and installing the first cylinder body on the inspection cover, the first cylinder body can be repaired and replaced when the inspection cover is removed.

[0020] Preferably, the outer diameter of the push plate matches the inner diameter of the regulating chamber.

[0021] By matching the outer diameter of the push plate with the inner diameter of the regulating chamber, the push plate can be removed together with the first cylinder body.

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] The utility model provides an adjusting bin, and a push plate is provided in the adjusting bin, and the push plate is fixedly connected to the first cylinder body, so that the phosphogypsum in the adjusting bin is pushed into the bin body by the push plate, and then the phosphogypsum in the bin body is pressurized, so that the phosphogypsum is squeezed, and then the total amount of phosphogypsum in the bin body is changed, and then the agglomerates are dispersed under the action of the squeezing force, so as to achieve the effect of rapid discharge of the phosphogypsum.
