A cement mixer and weighing structure

Abstract

This utility model provides a cement mixer and weighing structure, including: a cement mixer, which includes a mixing hopper and a feeding pipe. A set of feeding pipes for guiding the mixed raw materials are fixedly connected to both sides of the mixing hopper. Compared with the prior art, this utility model has the following beneficial effects: by adding a cement mixer, a steel belt elevator, and a weighing belt conveyor, the weighing belt conveyor weighs the raw materials and then feeds them into the weighing hopper. The steel belt elevator continuously lifts the materials and then discharges them through the outlet into the mixing hopper of the cement mixer. The materials are then fed into the mixing hopper through the feeding pipes to achieve cement mixing production. Continuous production can be achieved while weighing and proportioning. By adding the cement mixer and the steel belt elevator, some raw materials fall during the lifting process. These materials are collected below, weighed, and then discharged in a concentrated manner to reach the preset weight. The auxiliary weighing belt conveyor replenishes the raw materials, thus improving the accuracy of the proportioning.

Description

Technical Field

[0001] This utility model belongs to the field of cement mixing technology, and specifically relates to a cement mixer and weighing structure. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, the demand for cement continues to grow. To meet market demand, enterprises need to increase production capacity and optimize product quality. Cement mixers are crucial equipment in cement production, used to mix and stir the raw materials required for cement preparation. Before cement preparation, each raw material needs to be weighed according to the proportions. However, in traditional cement production, the weighing and proportioning are done manually, which places a significant burden on manual labor. Current technology, to reduce manual intervention, uses external weighing structures to weigh and proportion the materials before directly pouring them into the cement mixer. However, this method cannot achieve continuous, large-scale cement production.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5As the first embodiment of this utility model:

[0027] A cement mixer and weighing structure, comprising: a cement mixer 100, the cement mixer 100 including a mixing drum 101 and a feed pipe 102, and a set of feed pipes 102 for guiding the mixed raw materials are fixedly connected to both the left and right sides of the mixing drum 101.

[0028] A set of steel wire belt elevators 200 for continuous feeding is installed at the end of the feed pipe 102 away from the center of the cement mixer 100. The steel wire belt elevator 200 includes an elevator body 201, a weighing feed hopper 204 and a discharge port 202.

[0029] A weighing feed hopper 204 is fixedly connected to the lower right of the elevator body 201. This hopper is used to receive raw materials after weighing by the weighing belt conveyor 300. A weighing belt conveyor 300 is installed on the right side of the weighing feed hopper 204 to achieve accurate weighing and mixing of raw materials. A discharge port 202 is fixedly connected to the upper left of the elevator body 201.

[0030] A mixing feed hopper 103 is fixedly connected to one end of the feed pipe 102 away from the center of the cement mixer 100, and a connecting seat 104 is fixedly connected to the outer end of the mixing feed hopper 103 away from the center of the cement mixer 100.

[0031] A connecting seat 203 is fixedly connected to the lower left outer side of the discharge port 202. The connecting seat 104 and the connecting seat 203 are attached to each other and fixed with bolts. The discharge port 202 is connected to the mixing feed hopper 103 by connecting the connecting seat 104 and the connecting seat 203.

[0032] The elevator body 201 has several sets of raw material lifting buckets built in, which are used to receive the raw materials inside the weighing feed bucket 204 and lift them upward. The weighing belt conveyor 300 includes a raw material guide belt for weighing and guiding the raw materials and a weighing sensor for accurately weighing the raw materials. The weighing belt conveyor 300 is set independently. After weighing is completed, the raw materials are introduced into the lifting bucket for pre-weighing and batching. Then the lifting bucket rises to complete continuous feeding.

[0033] Specifically, in use, connecting seat 104 and connecting seat 203 are connected and fixed with bolts to complete the connection between the discharge port 202 and the mixing feed hopper 103. The raw materials used for cement mixing production are pre-weighed and batched by the weighing belt conveyor 300. The weighing belt conveyor 300 is set independently and is not affected by the weighing interference caused by the vibration of other equipment. After weighing, the raw materials are introduced into the lifting hopper for pre-weighing and batching. Then the lifting hopper rises to complete continuous feeding. After the lifting hopper rises to the end, it throws the raw materials into the discharge port 202, which is then received by the mixing feed hopper 103. The raw materials are then introduced into the mixing tank 101 through the feed pipe 102, thus enabling continuous production while weighing and batching.

[0034] Please see Figures 1-5 As a second embodiment of this utility model:

[0035] The lower inner side of the elevator body 201 is provided with a collection trough 212 for collecting and receiving falling raw materials. A falling hole 213 is provided below the collection trough 212. An auxiliary weighing belt conveyor 205 is also fixedly installed below the elevator body 201.

[0036] The drop hole 213 is located above the auxiliary weighing belt conveyor 205. A set of transmission shafts is rotatably connected to the right rear side of the auxiliary weighing belt conveyor 205, and a set of transmission pulleys 206 are fixedly connected to the outside of the transmission shafts.

[0037] A transmission belt 207 is sleeved on the outer side of the transmission pulley 206, and a transmission pulley 206 is also provided on the right side of the inner side of the transmission belt 207. A transmission pulley 208 is provided on the rear side of the transmission pulley 206.

A second transmission pulley 208 is also provided on the upper inner side of the second transmission belt 209. An auxiliary weighing conveyor belt 211 is provided on the rear side of the upper transmission pulley 208. An auxiliary hopper 210 for replenishing materials is provided below the auxiliary weighing conveyor belt 211. The steel wire belt elevator 200 lifts the raw materials. Some of the raw materials fall off and are collected and weighed below. After reaching the preset weight, they are discharged and replenished by the auxiliary weighing conveyor belt 211.

[0039] Based on the first embodiment described above, further, the steel wire conveyor belt elevator 200 lifts raw materials, some of which fall off. The fallen raw materials are collected below by the collection trough 212 and fall through the drop hole 213 to the top of the auxiliary weighing belt 205 below. After the weight reaches the preset weight, the materials are discharged and driven to rotate the first transfer belt pulley 206. The rotation is then transferred to the second transfer belt pulley 208 via the first transfer belt 207, and then transferred to the second auxiliary weighing belt 211 above via the second transfer belt 209. The auxiliary weighing belt 211 replenishes the raw materials, and then the materials are introduced into the lifting hopper above via the auxiliary hopper 210, thereby improving the accuracy of the proportioning.
