DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] like Figures 1 to 6 As shown, the utility model describes an improved multi-channel dynamic metering and static metering cement homogenizing equipment, comprising a storage warehouse 1, a transfer warehouse 2, a mixing system 3 and a conveying system 4, wherein the storage warehouse 1 is used to store cement masterbatch and auxiliary materials (the masterbatch refers to ground high-grade cement or clinker powder, and the auxiliary materials refer to other ground mixed materials); the transfer warehouse 2 is used to collect the mixed and homogenized cement; the mixing system 3 is arranged between the conveying system 4 and the transfer warehouse 2, and the mixing system 3 is used to promote the uniform mixing of various raw materials, thereby improving the uniformity and quality stability of cement; the conveying system 4 is used to convey the raw materials (the masterbatch and auxiliary materials with good proportions) to the mixing system 3; specifically, the mixing system 3 includes a mixer 3a, and a plurality of the mixers 3a are sequentially connected to the conveying system 4 along the conveying direction of the conveying system 4, and the conveying system 4 sequentially delivers the raw materials into the mixer 3a. The utility model simplifies the complex structure of the original equipment, can reduce unnecessary components and connecting parts, thereby reducing manufacturing costs and material consumption. In addition, the simplified equipment structure is often more intuitive and easy to understand, making maintenance and care more convenient and quick. At the same time, the utility model adopts a method of homogenizing cement using a multi-channel and multi-stage mixer 3a, which simplifies the equipment and improves the homogenization efficiency of the homogenization equipment.

[0028] Furthermore, it also includes a metering system 5 and a transfer system (not shown in the figure). The metering system 5 is arranged between the storage warehouse 1 and the conveying system 4. The metering system 5 is used to ensure the accuracy of the ratio between the masterbatch and the auxiliary material; the transfer system is used to transport the cement in the transfer warehouse 2 to the finished cement warehouse.

[0029] refer to Figure 2As shown, the mixer 3a includes a primary mixer 3a1, a secondary mixer 3a2 and a tertiary mixer 3a3. The primary mixer 3a1 is connected to the conveying system 4 in sequence along the conveying direction of the conveying system 4. The secondary mixer 3a2 is arranged between the primary mixer 3a1 and the tertiary mixer 3a3. The tertiary mixer 3a3 is arranged between the secondary mixer 3a2 and the transfer warehouse 2. The raw materials transported by the conveying system 4 first enter the primary mixer 3a1 for homogenization. After being homogenized in the primary mixer 3a1, the raw materials enter the secondary mixer 3a2 for secondary homogenization. After being homogenized twice in the secondary mixer 3a2, the raw materials enter the tertiary mixer 3a3 for tertiary homogenization. After being homogenized three times in the tertiary mixer 3a3, the raw materials enter the transfer warehouse 2. The primary mixer 3a1, the secondary mixer 3a2 and the tertiary mixer 3a3 mix and homogenize the masterbatch and the auxiliary materials three times, so that the masterbatch and the auxiliary materials can be fully mixed, which increases the mixing amount of the mixer 3a, thereby improving the homogenization efficiency. Similarly, refer to Figure 2 As shown, one or more mixers 3a can be arranged between the secondary mixer 3a2 and the transfer bin 2. The masterbatch and the auxiliary materials can be mixed and homogenized multiple times by multiple mixers 3a, so that the masterbatch and the auxiliary materials can be further fully mixed, further improving the mixing amount and homogenization effect of the mixer 3a, thereby further improving the homogenization efficiency, and then improving the uniformity and quality stability of the cement.

[0030] refer to Figure 3As shown, the conveying system 4 includes a conveying pipe 4a and a valve 4b, the storage 1 and the metering system 5 are arranged at the starting end (input end) of the conveying pipe 4a, and the mixing system 3 and the transfer bin 2 are arranged at the terminal end (output end) of the conveying pipe 4a. The raw materials (the masterbatch and the auxiliary materials with good proportions) in the metering system 5 enter the conveying pipe 4a at the starting end, and the raw materials (the masterbatch and the auxiliary materials with good proportions) in the conveying pipe 4a enter the mixing system 3 at the terminal end. When a plurality of the mixers 3a are sequentially connected to the conveying pipe 4a along the conveying direction of the conveying system 4, a valve 4b is provided on the conveying pipe 4a between every two adjacent mixers 3a. At the beginning, all valves 4b are closed, and the delivery pipe 4a first delivers the raw materials to the mixer 3a closest to the starting end. When the raw materials in the mixer 3a closest to the starting end reach the set value, the valve 4b on the delivery pipe 4a between the mixer 3a closest to the starting end and the adjacent mixer 3a is opened, and the delivery pipe 4a delivers the raw materials to the adjacent mixer 3a. At this time, the mixer 3a closest to the starting end starts to homogenize the raw materials, and the raw materials are delivered to the transfer warehouse 2 after homogenization. When the adjacent mixer 3a is When the raw material in the mixer 3a reaches the set value, the valve 4b on the conveying pipe 4a between the adjacent mixer 3a and the next mixer 3a is opened, and the conveying pipe 4a conveys the raw material to the next mixer 3a. At this time, the adjacent mixer 3a starts to homogenize the raw material, and the raw material is sent to the transfer warehouse 2 after homogenization; then repeat the above operation until the raw material in the last mixer 3a reaches the set value, all valves 4b are closed, and the conveying pipe 4a first delivers the raw material to the mixer 3a closest to the starting end.

[0031] refer to Figure 4 As shown, the mixing system 3 includes a one-way valve 3b, and the one-way valve 3b is arranged between the mixer 3a and the conveying system 4. When a plurality of the mixers 3a are connected to the conveying system 4 in sequence along the conveying direction of the conveying system 4, a valve 4b is arranged between all the mixers 3a and the conveying system 4. At the beginning, all the one-way valves 3b are in the open state, and the conveying system 4 first delivers the raw materials to the mixer 3a closest to the starting end. When the raw materials in the mixer 3a closest to the starting end reach the set value, the one-way valve 3b between the mixer 3a closest to the starting end and the conveying system 4 is closed, and the conveying system 4 delivers the raw materials to the adjacent mixer 3a. At this time, the mixer 3a closest to the starting end starts to homogenize the raw materials, and the raw materials are delivered to the transfer warehouse 2 after homogenization. When the raw materials in the adjacent mixer 3a reach the set value, the one-way valve 3b between the mixer 3a closest to the starting end and the conveying system 4 is closed, and the conveying system 4 delivers the raw materials to the adjacent mixer 3a. When the set value is reached, the one-way valve 3b between the adjacent mixer 3a and the conveying system 4 is closed, and the conveying system 4 delivers the raw materials to the next mixer 3a. At this time, the adjacent mixer 3a starts to homogenize the raw materials, and the raw materials are delivered to the transfer warehouse 2 after homogenization. Then the above operation is repeated until the raw materials in the last mixer 3a reach the set value, then the one-way valve 3b between the mixer 3a closest to the starting end and the conveying system 4 is opened, and the conveying system 4 first delivers the raw materials to the mixer 3a closest to the starting end.

[0032] refer to Figure 5 As shown, the storage 1 is provided with a plurality of discharge ports 1a, and a metering system 5 is provided between each discharge port 1a and the conveying system 4. By providing a plurality of discharge ports 1a, more raw materials can be conveyed to the conveying system 4 at the same time, thereby avoiding the congestion that may occur when a single discharge port 1a conveys materials, and improving the material conveying efficiency. At the same time, the design of a plurality of discharge ports 1a can make the conveying and management of materials more convenient and efficient. For example, when maintaining equipment or replacing the discharge port 1a, the conveying path and distribution ratio of the material can be adjusted more flexibly, reducing the difficulty of operation and management costs.

[0033] refer to Figure 6 As shown, the storage depot 1 is provided with a plurality of storage bins 1b, and a metering system 5 is provided between each storage bin 1b and the conveying system 4. By setting a plurality of storage bins 1b, the storage capacity of the entire storage depot 1 can be increased through the design of the plurality of storage bins 1b, thereby avoiding the accumulation and congestion caused by too much material. This is very important for some factories that need to store a large amount of materials. At the same time, the design of the plurality of storage bins 1b can load and unload materials at the same time, thereby improving the efficiency of the entire operation process. By reasonably arranging the operation tasks of each storage bin 1b, the peak and valley of operation can be avoided, and the production process can be further optimized. In addition, the design of the plurality of storage bins 1b can reduce the safety risks that may arise during the material storage process. For example, when a storage bin 1b fails or an accident occurs, other storage bins 1b can continue to operate normally, and will not have a significant impact on the entire production process.

[0034] refer to Figure 5 and Figure 6 As shown, the metering system 5 is a rotor metering scale, which has high metering accuracy and reliability and can meet the metering requirements of different raw materials. By accurately measuring the flow rate or weight of raw materials, it can reduce the waste and loss of raw materials, improve production efficiency, and ensure the quality and performance of cement produced by homogenization.
