Description

Technical Field

[0002] At present, the slurry preparation of calcium silicate board / fiber cement board production lines on the market is decentralized. The fresh slurry mixing tank and the return slurry mixing storage tank are arranged around the board making machine. The installation process is relatively complicated and troublesome, the installation cost is high, and it is not convenient for centralized management and transportation. The magazine particles produced by the vibrating frame screen and the slag remover are inconvenient to transport, occupying the ground passage, and the passages around the board making machine are not smooth, which is not conducive to equipment maintenance. The transportation of return slurry and mixed slurry depends on vertical pipeline slurry pumps. According to the calculation of 5,000 hours of annual operation, there are a total of 22kW pumps, with an annual operating power of 220,000 kW·h. The electricity bill is very considerable for annual operation. In addition, the operation of pump equipment requires regular replacement of impellers, etc. The maintenance and replacement involves the shutdown of the production line, which not only requires a considerable maintenance cost, but also affects the production capacity of the production line. In addition, the traditional slurry distribution line has many pipelines, and the connections between pipelines will cause the slurry or return slurry to accumulate in the pipeline once the pump is stopped during the production process, causing the pipeline to be blocked. In order to facilitate the cleaning and washing of the pipeline, a flushing system needs to be set up to regularly clean the residual slurry in the pipeline. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0024] Reference Figure 1-3The utility model provides an integrated step batching system, including a tower building 1; the tower building 1 is sequentially arranged with a return slurry mixing tank 5, a new slurry mixing tank 3 and a pre-mixing tank 2 from top to bottom; the discharge port of the return slurry mixing tank 5 is connected to the feed port of the new slurry mixing tank 3; the discharge port of the new slurry mixing tank 3 is connected to the feed port of the pre-mixing tank 2. The slurry storage tank is generally made of steel cylinder shape, and the tank volume is designed according to the production line capacity. In the actual production application process, the mortar, pulp, material separation, sanding powder, water and other materials required for the production of fiber cement board / calcium silicate board are weighed and sent to the vertical mixer in a certain order for mixing and stirring to prepare new slurry, and after the impurity particles are screened out, they are sent to the new slurry mixing tank 3 for storage. The slabs prepared by the slurry plate making machine 7 are formed into a blank of qualified size after the blanks on all sides are cut off. The cut blanks or unqualified blanks are collected and reused through the return material belt conveyor and other devices. In order to facilitate the preparation of return material slurry, the recovered blanks are required to be broken up by a double-shaft mixer to make them into small blanks, which are convenient for mixing with return water to prepare return material slurry. After the small blanks processed by the double-shaft mixer are measured, they are mixed and stirred with return water to prepare return material slurry. After the impurities are removed, they are stored in the return material slurry mixing storage tank 5. The return water can find the water inlet at the upper part of the return water tank barrel where the barrel and the cone intersect. The height of the return water tank is higher than the ground, so that the return water from the opening of the return water tank barrel can be taken to the return material slurry preparation area by gravity without external power.

[0025] When slurry preparation is required, there is no need for an external vertical slurry pump for transportation. The returned slurry uses gravity to flow to the new slurry mixing storage tank 3, and after being mixed and stirred with the fresh slurry, it flows to the pre-mixing tank 2 to prepare a mixed slurry that meets production requirements, thereby realizing material preparation and achieving the purpose of material transportation.

[0026] Furthermore, an impurity screening device 4 is provided at the feed inlet of the new slurry stirring tank 3; the discharge port of the return slurry stirring tank 5 is connected to the inlet of the impurity screening device 4. After the return slurry screens out the impurity particles, it flows into the new slurry stirring tank 3 and mixes with the fresh slurry. In order to reduce the process and energy consumption, the impurity screening device 4 is usually set up in the upper space of the fresh slurry stirring tank so that the slurry after the impurity treatment process can flow to the slurry stirring tank. The impurity screening device 4 is preferably a vibrating frame screen.

[0027] The inlet of the impurity screening device 4 is also connected to a new slurry delivery pipeline 401. The prepared new slurry can be pumped to the inlet of the impurity screening device 4 by an external vertical slurry pump to screen out impurity particles in the new slurry.

[0028] Specifically, a deslagging device 6 is provided at the feed inlet of the return slurry stirring storage tank 5. The prepared return slurry is pumped to the deslagging device 6 to remove impurities and then enters the return slurry stirring storage tank 5.

[0029] In order to facilitate the transportation of impurity particles generated by the impurity screening device 4 and the slag remover 6, the tower building 1 is provided with an impurity recovery pool; the impurity screening device 4 and the slag remover 6 are respectively connected to the impurity recovery pool through pipelines. The impurity recovery pool is preferably set on the ground floor of the tower building 1, and the impurities generated during the slurry preparation process flow to the ground floor through the pipeline for centralized recovery and treatment to avoid overflow.

[0030] Furthermore, the integrated step batching system also includes a pulping board making machine 7; the discharge port of the pre-mixing tank 2 is connected to the inlet of the pulping board making machine 7, and the mixed slurry in the pre-mixing tank 2 that meets the production requirements is subjected to subsequent production processes by the pulping board making machine 7. The tower building 1 and the pulping board making machine 7 can be arranged in a straight line, which effectively reduces the width of the production line layout. When multiple production lines are arranged together, the overall floor space of the multiple production lines can be effectively reduced, and the civil construction cost can be reduced. The crane arranged above the pulping board making machine 7 can reduce the span and also reduce the purchase cost of the crane.

[0031] The tower building 1 is a multi-layer frame structure, and the personnel inspection is concentrated in the tower building 1, which reduces the distance of the inspection back and forth, and is also more conducive to discovering the fault of the production line. In the detailed implementation method, a steel structure frame tower building 1 can be used. When the steel structure frame tower building 1 is used, it is prefabricated in the factory and assembled and installed at the construction site, saving the installation period. The tower building 1 can also use a concrete frame tower building 1. The cast-in-place concrete frame does not require the construction of the mixing tank foundation arranged on the ground. The construction is simple and fast, and maintenance-free in the later stage. The tower building 1 is generally arranged with four floors, and the total height does not exceed 16 meters. The pre-mixing tank 2 is arranged on the first floor (the bottom floor), the new slurry mixing tank 3 is installed on the second floor, the impurity screening device 4 is arranged on the third floor, the return slurry mixing tank 5 is installed on the fourth floor, and the slag remover 6 is arranged on the top surface of the tower building 1. Each frame structure of the tower building 1 is provided with a floor, which is convenient for the staff to conduct inspections and equipment maintenance.

[0032] Furthermore, the integrated step batching system further includes a clean water tank; the clean water tank is connected to the return slurry mixing tank 5 and the new slurry mixing tank 3 through pipelines to provide an external water source for them. The clean water tank can also be connected to the slag remover 6 through a pipeline to provide an external water source for the slag remover 6. When the height of the tower building 1 is equivalent to that of the clean return water tank, the tower building 1 and the clean water tank / return water tank can be installed in the same area and share a roof of the same height to achieve complete enclosure.

[0033] When the height of the water intake point on the clean water tank is lower than the slag remover 6, the return slurry stirring tank 5, and the new slurry stirring tank 3, a water pump is provided on the clean water tank; the water pump is connected to the return slurry stirring tank 5, the new slurry stirring tank 3 and / or the slag remover 6 through pipelines. When water is needed, the water pump is used to pump water from the clean water tank and send it to the corresponding equipment. The water pump can choose a muddy water sedimentation pit pump and be set at the bottom of the clean water tank. External water can be used in normal production, which will not cause the pump that transports external water to run for a long time, nor will it increase power. It will only be necessary to flush the residual slurry in the tank when production is stopped or product varieties are changed to ensure that no slurry remains in the tank.

[0034] Furthermore, a lifting device is provided on the top surface of the tower building 1 to facilitate lifting in the equipment maintenance room.

[0035] In summary, the integrated step batching system provided by the utility model adopts a tower building 1 to replace the method of arranging the tank body around the board making machine, and the batching system is highly integrated. The gravity is used to realize the self-flow of materials. There is no need to set a vertical slurry pump for returning slurry and a vertical slurry pump for mixing slurry to the pre-mixing tank 2. It can meet the requirements of each process, achieve the purpose of material transportation, and effectively avoid the disadvantages of the traditional batching system. The integrated step batching system has a simple structure, enhanced stability, improved production line capacity, simple pipelines, small footprint, and saves space around the board making machine, which is conducive to the inspection and maintenance of the board making machine. There are fewer pump equipment, which reduces the operating power and saves electricity. Through the clever modular setting, factory prefabrication can be carried out quickly, repeated design can be reduced, etc., greatly shortening the construction period and reducing construction and operation costs. In addition, the modular integrated tower batching system can be quickly put into use in new projects, and the various operating parameters can be effectively compared between different production lines, thereby providing improvement directions and benchmarking management for project improvement and project management.
