[0026] The production process of gypsum includes the step of gypsum powder. Gypsum powder can be used for tempering, mixing, cleaning and drying, homogenization, etc. Different gypsum powders with different requirements will undergo different process operations.

[0027] When gypsum powder is being processed, it is usually transported by bucket elevators. The bucket elevators carry the gypsum powder, lift it to a certain height and rotate it to dump the gypsum powder into designated equipment.

[0028] The bucket lift is provided with rotating shafts on the bottom and side walls. The bucket lift can be rotated by two rotating shafts and a mechanical arm connected to the rotating shafts to meet the needs of transporting gypsum powder. However, gypsum powder is easy to adhere to the rotating shafts and is easy to harden over time. Once hardened, it will cause friction or interference limit between the bucket lift and the rotating shaft, affecting the subsequent use of the bucket lift. For example, the bucket lift cannot be flipped to the predetermined angle, resulting in inaccurate control of the amount of gypsum powder and large deviations, affecting the processing of gypsum powder.

[0029] To do this, please refer to Figure 1 The present application provides a bucket elevator for conveying gypsum powder, including a bucket elevator body 1, a rotating shaft 2, a bearing 3, a sealing ring 4, a heat conduction plate 5 and a heating plate 6.

[0030] Please refer to Figure 1 , a mounting hole 11 is formed on the bucket lifting body 1. The bucket lifting body 1 may be a conventional bucket-shaped structure having an accommodating cavity 51, and its material may be a metal material, such as iron, steel, or other alloy products; the mounting hole 11 may be opened on the bucket lifting body 1, or may be connected to the bucket lifting body 1 through a tubular structure to form the mounting hole 11, and the tubular structure may be a steel pipe, and the connection between the tubular structure and the bucket lifting body 1 may be welding, bonding, or integral molding.

[0031] Please refer to Figure 1 , the shaft 2 is rotatably arranged in the mounting hole 11. The shaft 2 can be a metal shaft, the middle of the shaft 2 is connected to the shaft hole of the mounting hole 11, and both ends of the shaft 2 can extend outside the mounting hole 11 and can be connected to other structures, such as a mechanical arm, a hydraulic press or other connecting brackets.

[0032] Please refer to Figure 1 , the bearing 3 is arranged between the rotating shaft 2 and the mounting hole 11. The bearing 3 can be a conventional deep groove ball bearing 3 or a cylindrical roller bearing 3, both of which can achieve a stable connection relationship between the rotating shaft 2 and the inner wall of the mounting hole 11, and can also reduce the friction force when the rotating shaft 2 rotates, so that the rotating shaft 2 can rotate smoothly. The bearing 3 can be tightly connected with the rotating shaft 2 and the mounting hole 11.

[0033] Please refer to Figure 2 The sealing ring 4 is provided with two sealing rings, which are respectively provided at two openings of the two mounting holes 11 of the mounting hole 11, and the rotating shaft 2 passes through the mounting hole 11. The sealing ring 4 can be a rubber sealing ring 4, and the sealing ring 4 can be sealed with the mounting hole 11 and the rotating shaft 2 to prevent gypsum powder from entering the mounting hole 11.

[0034] Please refer to Figure 1 The heat conducting plate 5 is fixedly arranged on the bucket lifting body 1 and arranged at the mounting hole 11, and an accommodating cavity 51 is formed between the heat conducting plate 5 and the bucket lifting body 1. The heat conducting plate 5 can be made of a material with good thermal conductivity, such as iron, copper, or ceramic, and the heat conducting plate 5 and the bucket lifting body 1 can be connected by any of bonding, welding, integral molding, clamping, and bolting.

[0035] Please refer to Figure 1 The heating plate 6 is arranged in the accommodating cavity 51, and the heating plate 6 is arranged in contact with the heat conducting plate 5. The heating plate 6 can be an electric heating plate 6, such as an aluminum plate, a carbon crystal electric heating plate, a ceramic plate with a built-in heating wire, etc.

[0036] Please refer to Figure 1 and Figure 2 The outer wall surface of the bucket lifting body 1 is also formed with a water flow groove 12, which is arranged at the openings on both sides of the mounting hole 11. The water flow groove 12 can be opened on the outer wall of the bucket lifting body 1, and the water flow groove 12 can be connected as a whole, and openings are formed at the head and tail to facilitate water outflow.

[0037] Please refer to Figure 1The sealing ring 4 in the present application can seal the rotating shaft 2, the bearing 3 and the mounting hole 11 to prevent the gypsum powder from entering the mounting hole 11. The heating plate 6 and the heat conducting plate 5 are arranged outside the mounting hole 11, and can heat the area where the mounting hole 11 is located. On the one hand, the temperature here can be increased and the humidity can be reduced, thereby reducing the possibility of gypsum powder hardening. On the other hand, the area outside the mounting hole 11 can be quickly dried after being flushed with water to prevent the gypsum powder from hardening. The water flow trough 12 can make water flow out quickly during water flushing, reducing the possibility of gypsum powder hardening caused by residual moisture.

[0038] Please refer to Figure 1 This structure can prevent a large amount of gypsum powder from compacting between the bucket lift body 1 and the rotating shaft 2 during use, and at the same time avoid excessive friction between the rotating shaft 2 and the bucket lift body 1 caused by the compaction of gypsum powder, thereby ensuring the rotational connection relationship between the rotating shaft 2 and the bucket lift body 1, so that the bucket lift body 1 can transport gypsum powder more stably and with more accurate transport volume.

[0039] The heating plate 6 and the heat conducting plate 5 in this solution can heat the mounting hole 11, thereby reducing the humidity there, making the gypsum powder drier and avoiding hardening.

[0040] At the same time, the gypsum powder at the mounting hole 11 can be cleaned regularly, such as by flushing with water. At the same time, the heating plate 6 and the heat conducting plate 5 can make the moisture at the mounting hole 11 dry quickly to avoid affecting normal operation.

[0041] When an unexpected situation causes moisture to appear in the mounting hole 11, the heating plate 6 and the heat conducting plate 5 will cause the gypsum powder in this area to react quickly with water and solidify. This needs to be dealt with as soon as possible to avoid the growth of lumps due to long-term use and affecting the normal operation of the bucket elevator body 1.

[0042] Please refer to Figure 2 In some examples, the heat conducting plate 5 is disposed around the mounting hole 11. The surrounding structure can heat more areas at the mounting hole 11.

[0043] In some examples, the heat conducting plate 5 is arranged around the mounting hole 11.

[0048] Please refer to Figure 2 In some examples, the heating plate 6 is an electric heating plate 6, and a circuit electrically connected to the electric heating plate 6 is provided in the bucket body 1. The electric heating plate 6 can have a more stable heating effect. The heating plate 6 has been described above and will not be described again here.

[0049] Please refer to Figure 2 In some examples, the mounting hole 11 includes a first mounting hole and a second mounting hole, the first mounting hole is arranged at the bottom of the bucket lifting body 1, the second mounting hole is arranged on the side wall of the bucket lifting body 1, the axis of the first mounting hole and the axis of the second mounting hole are parallel to each other; the first mounting hole and the second mounting hole are both provided with a rotating shaft 2. The multiple rotating shafts 2 can cooperate with each other to realize the rotation of the bucket lifting body 1.

[0050] For example, at this time, the bucket body 1 can be rotated by the cooperation of the rotating shaft 2 in the first mounting hole and the second mounting hole, so as to pour out the gypsum powder.

[0051] Please refer to Figure 2 In some examples, a plurality of first mounting holes are provided, and the plurality of first mounting holes are spaced apart along the axis of the first mounting hole; a plurality of second mounting holes are provided, and the plurality of second mounting holes are spaced apart along the axis of the second mounting hole.

[0052] Exemplarily, the number of the first mounting holes and the second mounting holes can be set to three, the three first mounting holes can be distributed at equal intervals, the three second mounting holes can also be distributed at equal intervals, and the three first mounting holes and the three second mounting holes can be set in one-to-one correspondence.

[0053] Please refer to Figure 2 Alternatively, it can also be set to two, with the two first mounting holes and the two second mounting holes both being arranged on opposite sides of the bucket lift.

[0054] Please refer to Figure 2In some examples, the heat conducting plate 5 and the heating plate 6 are arranged at the first mounting hole. In this case, the first mounting hole can be heated well, the gypsum powder adhered to the bucket body 1 at the first mounting hole can be prevented from hardening, and the stable rotation effect of the rotating shaft 2 in the first mounting hole can be ensured.

[0055] In some examples, when there are multiple first mounting holes, the above-mentioned heat conducting plate 5 and heating plate 6 can be arranged outside each first mounting hole, so that the first mounting hole can have a better thermal effect, thereby producing a better effect of preventing hardening.
