Description

Technical Field

[0001] This utility model relates to the field of cement technology, and in particular to a raw material addition device for cement production. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or, even better, in water, and can firmly bind materials such as sand and stone together. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

[0003] During cement processing, additives are typically added to the cement mixing tank using a batching hopper to meet the production needs of different cements. However, traditional cement batching hoppers do not have a metering component at the bottom, making it inconvenient to add additives in a measured amount, which makes it difficult to control the amount of additives added and can easily affect the mixing effect of cement processing. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a raw material addition device for cement production. This device can solve the problem that the bottom of the traditional cement batching hopper does not have a related quantitative addition component, which makes it inconvenient to quantitatively add additive raw materials to the batching hopper, and thus makes it inconvenient to control the amount of additives added.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material addition device for cement production, comprising a cement mixing tank, a support plate fixedly connected to the top of the cement mixing tank, a metering box fixedly installed on the top of the support plate, the bottom of the metering box being open, a batching hopper fixedly connected to the top of the metering box, the interior of the metering box communicating with the interior of the batching hopper, a metering dispensing assembly provided inside the metering box, the metering dispensing assembly comprising a metering column, the two ends of the metering column being rotatably connected to the two sides of the inner wall of the metering box, and metering grooves being provided on the upper and lower sides of the surface of the metering column.

[0010] Preferably, a connecting column is fixedly connected to the bottom end of the rotating column, and a cross stirring rod is fixedly installed at the bottom end of the connecting column, with the cross stirring rod located above the metering column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This cement production raw material addition equipment uses two sequentially rotating quantitative tanks to facilitate the quantitative feeding of additive raw materials, thereby improving the processing of cement inside the cement mixing tank.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a raw material addition device for cement production, including a cement mixing tank 1, a support plate 2 fixedly connected to the top of the cement mixing tank 1, a metering box 3 fixedly installed on the top of the support plate 2, the bottom of the metering box 3 being open, a batching hopper 4 fixedly connected to the top of the metering box 3, the interior of the metering box 3 communicating with the interior of the batching hopper 4, a metering dispensing component being provided inside the metering box 3, the metering dispensing component including a metering column 12, the two ends of the metering column 12 being rotatably connected to the two sides of the inner wall of the metering box 3, and metering grooves 13 being provided on the upper and lower sides of the surface of the metering column 12.

[0024] Furthermore, a second motor 9 is rotatably mounted on one side of the metering box 3. The output end of the second motor 9 rotates through the interior of the metering box 3 and is fixedly connected to one end of the metering column 12.

[0025] Furthermore, a fixing plate 5 is fixedly installed inside the batching hopper 4. A first motor 8 is rotatably connected to the top of the fixing plate 5. The output end of the first motor 8 rotates through the interior of the fixing plate 5 and is fixedly connected to a rotating column 6. The rotating column 6 is located inside the batching hopper 4, and two stirring crossbars 7 are fixedly sleeved on the outer surface of the rotating column 6.

[0026] Furthermore, a connecting column 10 is fixedly connected to the bottom end of the rotating column 6, and a cross stirring rod 11 is fixedly installed at the bottom end of the connecting column 10. The cross stirring rod 11 is located above the metering column 12.

[0027] Furthermore, after the additive raw materials enter the batching hopper 4, the first motor 8 is started. The output end of the first motor 8 drives the rotating column 6 to rotate. The two stirring crossbars 7 fixedly sleeved on the outer surface of the rotating column 6 rotate accordingly, stirring and dispersing the additive raw materials in the batching hopper 4. The connecting column 10 fixedly connected to the bottom of the rotating column 6 and the cross stirring rod 11 at the bottom of the connecting column 10 also rotate together. The cross stirring rod 11 is located above the metering column 12, which can stir and guide the additive raw materials that are about to enter the metering tank 13, thereby preventing the additive raw materials from accumulating and blocking the connection between the batching hopper 4 and the metering box 3. This will not affect the continuous filling of the metering tank 13, thus ensuring that the amount of additive raw materials in the metering tank 13 is the same each time, so that the subsequent cement mixing tank 1 can better process cement.

[0028] Furthermore, when the additive raw materials enter the metering tank 3 through the batching hopper 4, since the upper metering trough 13 is in communication with the inside of the batching hopper 4, the upper metering trough 13 can receive and limit a certain amount of raw materials. At this time, the second motor 9 is started, and the output end of the second motor 9 drives the metering column 12 to rotate. When the upper metering trough 13 rotates to the position where the opening is downward, the additive raw materials contained therein will fall from the bottom opening of the metering tank 3 by its own gravity, realizing metered feeding and ensuring that the amount of additive raw materials added to the cement mixing tank 1 each time is accurate and controllable. Then, the lower metering trough 13 will reconnect with the inside of the batching hopper 4 and receive the additive raw materials. Thus, by rotating the two metering troughs 13 in turn, one of the two metering troughs 13 will always be full of additive raw materials, which facilitates the mixing and processing of cement inside the cement mixing tank 1.

[0029] Furthermore, by rotating the two metering tanks 13 in sequence, it is convenient to meter the additive raw materials, thereby enabling better processing of the cement inside the cement mixing tank. At the same time, the rotation of the cross stirring rod 11 can prevent the additive raw materials from accumulating and clogging at the connection between the batching hopper 4 and the metering box 3, thus not affecting the continuous loading of the metering tank 13, thereby improving the practicality of the additive equipment.

[0030] Structural Description:

[0031] Cement mixing tank 1: As the core of the equipment, it is used to receive quantitatively added additive raw materials and cement, and fully mix the two through an internal mixing device to complete the mixing process of cement production. It is a key container for the preparation of finished cement products.

[0032] Support plate 2: It serves as a support and is fixed to the top of the cement mixing tank 1, providing a stable installation foundation for the metering tank 3 above, ensuring the stability of the overall structure of the equipment, and preventing the metering tank 3 from shaking or shifting during operation.

[0033] Quantitative tank 3: Responsible for quantitative control of additive raw materials. Its bottom opening design allows the quantitative raw materials to fall smoothly into the cement mixing tank 1. The internal quantitative feeding component, together with the quantitative trough 13, realizes the accurate measurement and delivery of additive raw materials.

[0034] The mixing hopper 4 is the channel through which additive raw materials enter the metering box 3. Its internal space is used to receive the raw materials and, together with the internal stirring structure, to stir and disperse the raw materials, while guiding the raw materials to the metering box 3 to ensure the smooth transport of raw materials.

[0035] Fixed plate 5: Installed inside the batching hopper 4, used to fix the first motor 8, providing a support point for the rotation of the rotating column 6, so that the rotating column 6 and its attached stirring structure can operate stably, thereby effectively stirring the raw materials.

[0036] Rotating column 6: Driven by the first motor 8, it rotates, and the stirring crossbar 7 fixedly sleeved on the outer surface rotates with it, stirring and mixing the additive raw materials in the batching hopper 4. The connecting column 10 and cross stirring rod 11 connected at the bottom stir and guide the raw materials that are about to enter the metering tank 13 to prevent the raw materials from accumulating and blocking.

[0037] Stirring bar 7: It is fixedly sleeved on the outer surface of the rotating column 6. When the rotating column 6 rotates, it stirs the additive raw materials in the mixing hopper 4 in the horizontal direction, increases the dispersion of the additive raw materials, makes them more uniformly mixed, and improves the fluidity of the raw materials.

[0038] First motor 8: Provides power to the rotating column 6 and its associated stirring structure. It drives the rotating column 6 to rotate through the output end, thereby driving the stirring crossbar 7 and the cross stirring rod 11 to stir the raw materials, ensuring that the raw materials are fully mixed before entering the metering box 3.

[0039] The second motor 9 is connected to the metering column 12 and drives the metering column 12 to rotate through its output end. This causes the metering groove 13 on the surface of the metering column 12 to circulate and add additive raw materials, thereby realizing the function of metering the raw materials and ensuring that the amount of raw materials added to the cement mixing tank 1 each time is accurate and controllable.

[0040] Connecting column 10: One end is fixedly connected to the bottom end of the rotating column 6, and the other end is connected to the cross stirring rod 11, which transmits the rotation of the rotating column 6 to the cross stirring rod 11, so that the cross stirring rod 11 can stir and guide the raw material above the metering column 12 to prevent the raw material from clogging.

[0041] Cross-shaped stirring rod 11: Located above the metering column 12, it rotates under the drive of the connecting column 10 to stir the raw materials that are about to enter the metering tank 13, preventing the raw materials from accumulating at the connection between the batching hopper 4 and the metering box 3, and ensuring that the metering tank 13 can continuously and stably fill the material.

[0042] The metering column 12 is rotatably connected to the inner wall of the metering box 3 at both ends. The metering groove 13 on the surface is used to receive and limit a certain amount of additive raw materials. It rotates under the drive of the second motor 9 to realize the metered delivery of raw materials and ensure that the amount of raw materials added to the cement mixing tank 1 is consistent each time.

[0043] Metering trough 13: It is opened on the upper and lower sides of the surface of metering column 12. Its volume is fixed and it is used to accurately measure additive raw materials. When the opening of metering trough 13 is facing downward, the raw materials are fed quantitatively by their own gravity, ensuring that the amount of raw materials added to cement mixing tank 1 is accurate and controllable. Furthermore, by having two metering troughs 13 work alternately and cyclically, the feeding efficiency is improved.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
