Description

Technical Field

[0001] The utility model belongs to the technical field of weighing devices for cement processing, in particular to a weighing device for cement processing with good cleaning effect. Background Art

[0002] Cement is a powdered hydraulic inorganic cementitious material that forms a slurry when mixed with water. It can harden in air or water, and can firmly bind materials such as sand and stone together. The early mixture of lime and volcanic ash is very similar to modern lime-volcanic ash cement. Concrete made of crushed stone is not only strong after hardening, but also resistant to erosion by fresh or salt water. For a long time, it has been widely used as an important cementitious material in civil construction, water conservancy, national defense and other projects.

[0003] At present, in the process of cement production and processing, in order to ensure the accuracy of cement weight, a weighing device is needed to weigh it. However, common weighing devices are not convenient for removing cement after weighing. As a result, a part of cement will remain in the weighing device every time it is taken out, which greatly wastes resources and affects the accuracy of weighing. In addition, the cement is discharged slowly after being taken out and weighed.

[0004] A Chinese patent with authorization announcement number CN213386804U discloses a novel weighing device for cement processing, comprising a base plate, an adjustment mechanism, a weighing mechanism, and a feeding mechanism, wherein the adjustment mechanism is arranged on top of the base plate, the weighing mechanism is arranged on the adjustment mechanism, and the feeding mechanism is arranged on the adjustment mechanism, and the adjustment mechanism includes a fixed plate, and the fixed plate is arranged above the base plate. Through the mutual cooperation of the concave plate, the fixed shaft, the support block, the fixed block, the connecting shaft, the movable block, the electric push rod, the cylinder, the push plate, and the discharge cover, the cement can be quickly discharged from the weighing box after weighing is completed, so as to improve work efficiency, avoid residual cement remaining in the weighing box, ensure weighing accuracy, avoid waste of resources, and through the mutual cooperation of the servo motor and the stirring rod, the phenomenon of cement clogging during feeding is avoided, thereby improving the liquidity of the cement.

[0005] However, the above patent has the following disadvantages:

[0006] After long-term use, the push plate of the above-mentioned patent will wear out, which will cause a gap to appear between the push plate and the weighing box, making it impossible to fit tightly. When weighing and discharging cement for spraying, the worn push plate will make it difficult to achieve a good effect of scraping off residual cement, thereby affecting the accuracy of weighing. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of arranging a conical upper cone barrel so that cement adhering to the inner wall of the upper cone barrel is easier to fall off during discharge, thereby reducing the residual amount of cement in the weighing device and improving the accuracy of cement weighing. In addition, a spiral scraper is used to scrape the inner wall of the upper cone barrel during discharge, thereby completely scraping off the cement remaining on the inner wall of the upper cone barrel. When the spiral scraper and the upper cone barrel are worn and the degree of fit between the two decreases, the cylinder is controlled to pull the bracket upward, so that the spiral scraper can be closely fitted to the inner wall of the upper cone barrel again, thereby ensuring the effect of scraping off the residual cement.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0012] The scraper component includes a feed shell, which is fixedly connected to the top of the upper conical barrel. A feed port connected to the interior is opened on one side of the feed shell. A rotating shaft is rotated and slidably connected inside the feed shell. The part of the rotating shaft extending into the upper conical barrel is fixedly connected to a bracket, and a plurality of spiral scraping strips that fit tightly with the inner wall of the cone of the upper conical barrel and slide relative to each other are fixedly connected to the bracket.

[0013] The spiral scraper is used to scrape the inner wall of the upper cone barrel during discharge, so that the cement remaining on the inner wall of the upper cone barrel is completely scraped off, further avoiding cement residue and improving the accuracy of weighing.

[0014] The rotating shaft extends out of the top of the feed shell and is rotatably connected to a cylinder seat. A motor is fixedly connected to the upper side of the cylinder seat. The motor is transmission-connected to the rotating shaft. A plurality of cylinders surrounding the outside of the motor are evenly distributed and fixedly connected on the upper side of the cylinder seat. The extended end of each cylinder passes through the cylinder seat and is fixedly connected to the feed shell.

[0015] When the spiral scraper and the upper cone barrel are worn and the fit between the two decreases, the cylinder is controlled to pull the bracket upward, so that the spiral scraper can fit closely with the inner wall of the upper cone barrel again, thereby ensuring the effect of scraping off residual cement.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] refer to Figure 1-4 A cement processing weighing device with good cleaning effect includes an upper cone barrel 40, a lower cone barrel 41 is fixedly connected to the bottom of the upper cone barrel 40, a discharge valve 16 is fixedly connected to the bottom of the lower cone barrel 41, a scraper component is provided in the upper cone barrel 40, the main body of the upper cone barrel 40 is a right cone with a small taper, and the main body of the lower cone barrel 41 is an inverted cone with a large taper.

[0026] By providing the conical upper cone barrel 40, cement adhering to the inner wall of the upper cone barrel 40 is easier to fall off during discharge, thereby reducing the residual amount of cement in the weighing device and improving the accuracy of cement weighing.

[0027] refer to Figure 1 A plurality of weight sensors 19 are evenly distributed and fixedly connected to the bottom side of the top flange portion of the upper cone barrel 40, an annular weighing plate 18 is fixedly connected to the bottom of the plurality of weight sensors 19, and a plurality of columns 10 are evenly distributed and fixedly connected to the bottom of the weighing plate 18 in a circumferential direction.

[0028] refer to Figure 3-4 The scraper component includes a feed shell 42, which is fixedly connected to the top of the upper cone barrel 40. A feed port 43 connected to the interior is provided on one side of the feed shell 42. A rotating shaft 46 is rotatably and slidably connected inside the feed shell 42. The part of the rotating shaft 46 extending into the upper cone barrel 40 is fixedly connected to a bracket 48, and a plurality of spiral scraping strips 47 that fit tightly with the conical inner wall of the upper cone barrel 40 and slide relatively are fixedly connected to the bracket 48.

[0029] The spiral scraper 47 is used to scrape the inner wall of the upper cone barrel 40 during discharge, thereby completely scraping off the cement remaining on the inner wall of the upper cone barrel 40, further avoiding cement residue and improving the accuracy of weighing.

[0030] refer to Figure 1-3 The rotating shaft 46 extends out of the top of the feed shell 42 and is rotatably connected to the cylinder seat 44. The upper side of the cylinder seat 44 is fixedly connected to the motor 35. The motor 35 is transmission-connected to the rotating shaft 46. A plurality of cylinders 45 surrounding the outside of the motor 35 are evenly distributed and fixedly connected on the upper side of the cylinder seat 44. The extended end of each cylinder 45 passes through the cylinder seat 44 and is fixedly connected to the feed shell 42.

[0031] When the spiral scraper 47 and the upper cone barrel 40 wear out and the fit between the two decreases, the cylinder 45 is controlled to pull the bracket 48 upward, so that the spiral scraper 47 can fit tightly with the inner wall of the upper cone barrel 40 again, thereby ensuring the effect of scraping off residual cement.

[0032] In this embodiment, initially, the operator connects the power supply and control system of this patent, the cylinder 45 is connected to the pneumatic control element, and the feed port 43 is connected to the injection equipment. At this time, the discharge valve 16 is in a closed state, the spiral scraper 47 is tightly fitted with the inner wall of the upper cone barrel 40, the weight sensor 19 is connected to the control system, and when there is no cement in the upper cone barrel 40 and the lower cone barrel 41, the control system displays the weight as zero.

[0033] The operator then injects cement into the upper cone barrel 40 and the lower cone barrel 41 through the injection equipment. When the injection stops, the weight of the cement in the upper cone barrel 40 and the lower cone barrel 41 acts evenly on the weight sensor 19, and the weight of the cement is measured and read by the weight sensor 19 to achieve the purpose of weighing.

[0034] When discharging, the operator opens the discharge valve 16, and the cement in the upper cone barrel 40 and the lower cone barrel 41 converges to the center along the cone surface of the lower cone barrel 41 and is finally discharged from the discharge valve 16. The cement remaining on the inner wall of the upper cone barrel 40 is easier to fall off due to the taper of the upper cone barrel 40, thereby reducing the residual amount of cement in the weighing device and improving the accuracy of cement weighing.

[0035] At the same time, when the motor 35 is started, the rotating shaft 46 drives multiple spiral scrapers 47 to rotate. The spiral scrapers 47 continuously scrape the inner wall of the upper cone barrel 40, scraping the cement remaining on the inner wall of the upper cone barrel 40 and pushing it downward, thereby completely scraping off the cement remaining on the inner wall of the upper cone barrel 40, further avoiding cement residue and improving the accuracy of weighing.

[0036] When the spiral scraper 47 and the upper cone barrel 40 wear out and the fit between the two decreases, the cylinder 45 is controlled to pull the bracket 48 upward, so that the spiral scraper 47 can fit tightly with the inner wall of the upper cone barrel 40 again, thereby ensuring the effect of scraping off residual cement.
