Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a weighing structure for a cement raw material proportioning device. Background Art

[0002] The main raw materials of cement are limestone, sandstone, silica, and some also add fly ash or iron ore, copper slag, etc. The existing raw material mixing device for preparing cement mortar generally weighs the raw materials according to a certain ratio, and then transfers them to a mixing drum for stirring and mixing. This operation method has many links, is troublesome to operate, reduces processing efficiency, and the raw materials are easy to lose during the transfer process, resulting in a large ratio error, which affects the processing quality of cement mortar.

[0003] At present, a Chinese patent discloses a raw material mixing and proportioning device for preparing cement mortar (publication number CN211030613U). By setting a weighing mechanism, the raw materials are injected into the barrel and fall onto the weighing plate in the measuring chamber. The slider is slidably connected to the slide groove, and the slide groove follows the weighing plate to press down, exerting pressure on the weighing sensor. The weight data is transmitted to the display for weight measurement, which can accurately measure the raw materials and make the raw material proportioning quality higher.

[0004] Since the above-mentioned device sets the slider and the weighing sensor inside the chute, and the chute is exposed inside the measuring chamber, many raw materials of cement are in powder or small granular form. When the powder or small granular raw materials enter the measuring chamber, the raw materials can easily enter the chute, which will undoubtedly affect the normal operation of the slider and the weighing sensor, and easily affect the weighing accuracy of the raw materials inside the measuring chamber and the barrel.

[0005] Therefore, a weighing structure for a cement raw material proportioning device is proposed to solve the above problems. Utility Model Content

Compared with the method of measuring inside the barrel, this can ignore the obstruction of the inner wall of the barrel to the raw material, so that the weighing sensor can weigh the raw material inside the barrel more accurately, thereby improving the accuracy of the raw material weighing.

[0011] Preferably, the cross-sectional shape of the flexible dust cover is wavy, and the flexible dust cover is a high-density polyethylene material component, which can provide the flexible dust cover with sufficient expansion and contraction space to reduce the obstruction of the protective mechanism to the weighing mechanism.

[0012] Preferably, a guide hole is opened on the surface of the movable ring, and a threaded column threadedly connected to the mounting ring is inserted into the inner wall of the guide hole. The mounting ring and the movable ring are threadedly connected through the threaded column, which enables the staff to easily remove the movable ring to facilitate the staff to maintain the structure inside the ring.

[0013] Preferably, the other end of the threaded column is fixedly connected to an adjusting rod, and the corners of the adjusting rod are rounded, which can make it more convenient for the staff to rotate the threaded column, thereby reducing the difficulty of use for the staff.

[0024] like Figure 3 and Figure 4 As shown, a mounting groove 511 is provided at the top of the ring 51, and the weighing mechanism 52 includes a mounting ring 521 fixedly connected to the surface of the barrel 1, a guide rod 522 slidably connected to the mounting groove 511 is fixedly connected to the bottom of the mounting ring 521, and a weighing sensor 523 fixedly connected to the mounting groove 511 is fixedly connected to the bottom of the guide rod 522; the number of the mounting groove 511, the guide rod 522 and the weighing sensor 523 are not less than three, the number of the mounting groove 511, the guide rod 522 and the weighing sensor 523 are the same, and the mounting groove 511, the guide rod 522 and the weighing sensor 523 are distributed in a ring shape on the surface of the ring 51 around the axis of the ring 51.

[0025] like Figure 3 and Figure 4 As shown, the protective mechanism 53 includes a fixed ring 531 fixedly connected to the surface of the ring 51, a flexible dust cover 532 is fixedly connected to the top of the fixed ring 531, the flexible dust cover 532 is sleeved on the surfaces of the ring 51 and the mounting ring 521, the guide rod 522 is arranged on the inner side of the flexible dust cover 532, and the top of the flexible dust cover 532 is fixedly connected to the movable ring 533 on the surface of the mounting ring 521; during the operation of the weighing mechanism 52, the fixed ring 531, the flexible dust cover 532 and the movable ring 533 are combined together to block the gap between the mounting ring 521 and the ring 51, so that the guide rod 522 always operates in a clean environment. , reducing the activity resistance between the guide rod 522 and the mounting groove 511, further reducing the impact on the weighing of the weighing sensor 523, thereby improving the overall weighing accuracy of the weighing mechanism 52; the cross-sectional shape of the flexible dust cover 532 is wavy, and the flexible dust cover 532 is a high-density polyethylene material component; a guide hole 534 is opened on the surface of the movable ring 533, and a threaded column 535 threadedly connected to the mounting ring 521 is inserted into the inner wall of the guide hole 534, and the mounting ring 521 and the movable ring 533 are threadedly connected through the threaded column 535; the other end of the threaded column 535 is fixedly connected to the adjusting rod 536, and the corners of the adjusting rod 536 are rounded.

[0026] When the utility model is in use, the barrel 1 drives the electric discharge valve 3 to press down the mounting ring 521, and the mounting ring 521 presses down the weighing sensor 523 through the guide rod 522. At this time, the weighing sensor 523 detects the pressure value and transmits it to the controller 2. The staff can clearly observe the weight measurement value of the weighing sensor 523 before weighing the raw material through the controller 2.

At this time, the barrel 1 is connected with the guide pipe 4, and the raw material enters the guide pipe 4 along the barrel 1. The guide pipe 4 guides the raw material into the raw material proportioning mixer below for mixing.

[0027] In summary, compared with the existing weighing structure for cement raw material proportioning device, the weighing mechanism 52 is directly arranged on the outside of the barrel 1. At this time, the weighing mechanism 52 and the raw material are separated by the barrel 1, and there is no need to worry about the raw material contacting the weighing mechanism 52, thereby reducing the probability of the raw material affecting the operation of the weighing mechanism 52, thereby improving the weighing accuracy of the weighing mechanism 52. Moreover, the weighing mechanism 52 weighs the raw material together with the barrel 1. Compared with the method of measuring inside the barrel 1, this can ignore the obstruction of the inner wall of the barrel 1 to the raw material, so that the weighing sensor 523 can weigh the raw material inside the barrel 1 more accurately, thereby improving the accuracy of the raw material weighing.
