Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement production material conveying technology, and in particular to a powder material warehousing device. Background Technology
[0002] Cement production raw materials are generally powdery materials, such as fly ash. These materials often contain a certain amount of impurities. When these impurities enter a weighing scale (such as a rotor scale or Coriolis scale), larger particles can jam the rotor and cause the scale to stop, resulting in unplanned downtime.
[0003] Currently, when powdered raw materials for cement production are unloaded from tank trucks into the silo, they are directly discharged into the silo through the ash discharge pipe. Since the metering equipment at the bottom of the silo is usually in operation, the large impact force during the silo entry process causes the metering scale to fluctuate significantly, which seriously affects the metering accuracy and stability, resulting in significant fluctuations in the production system. Therefore, a powder material silo entry device is being developed. Utility Model Content
[0004] The purpose of this invention is to provide a powder material warehousing device to solve the technical problems mentioned in the background section.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The feed end of the tank truck connector is connected to a corresponding hose on the tank truck, and the discharge end of the tank truck connector is connected to the feed end of a separator. The separator is equipped with a counter-attack plate inside and a cleaning port at the bottom. The discharge end of the separator is connected to the feed end of a disperser located at the top of the silo through a conveying pipeline. The disperser is equipped with uniformly arranged dispersing blades inside, all of which face the inside of the silo.
[0007] Furthermore, the impurity remover includes a semi-circular connecting pipe, the two ends of which are connected to the tank truck connector and the conveying pipeline respectively via flanges. A collection box is provided at the bottom of the semi-circular connecting pipe. The collection box includes a semi-circular pipe body, a cuboid box body, and a conical box body arranged sequentially from top to bottom. The semi-circular pipe body is connected to the semi-circular connecting pipe. The impact plate is fixedly installed inside the cuboid box body. The impurity removal port includes a blind plate that is detachably connected to the bottom of the conical box body via a flange.
[0008] Furthermore, there are two counter-attack plates, which are arranged in parallel inside the cuboid box.
[0009] Furthermore, the conveying pipeline includes multiple straight feed pipes. Two feed pipes located at both ends are connected to the semi-circular connecting pipe and the feed end of the disperser through flanges, respectively. Wear-resistant elbows are provided between each pair of adjacent feed pipes through flanges.
[0010] Furthermore, the disperser includes an inlet pipe and a variable diameter cone arranged sequentially from top to bottom, and a plurality of dispersing blades are evenly arranged circumferentially inside the variable diameter cone; the upper end of the inlet pipe is connected to the corresponding feed pipe through a flange, and the variable diameter cone includes a conical box connected to the lower end of the inlet pipe and whose inner diameter increases sequentially from top to bottom, and the lower end of the conical box is connected to a cylindrical box for supporting the connecting silo.
[0011] Furthermore, a supporting guide cone is fixedly provided in the middle of the variable diameter cone, and the inner ends of the plurality of dispersing blades are fixedly connected to the outer peripheral wall of the supporting guide cone, and the outer ends of the plurality of dispersing blades are fixedly connected to the inner peripheral wall of the cylindrical box.

[0023] like Figure 1 As shown, a powder material receiving device includes a tank truck connector 1, the inlet of which is connected to a corresponding outlet hose on the tank truck. The outlet of the tank truck connector 1 is connected to the inlet of a separator 2. An impact plate 2-1 is fixedly and inclined inside the separator 2, and a cleaning port 2-2 is provided at the bottom of the separator 2. The outlet of the separator 2 is connected to the inlet of a disperser 3 installed at the top of the silo via a conveying pipeline. Multiple dispersing blades 3-1 are evenly and uniformly fixedly arranged circumferentially inside the disperser 3, with each dispersing blade 3-1 facing inwards from the silo.
[0024] like Figures 2-4 As shown, the impurity remover 2 includes a semi-circular connecting pipe 2-3, which is a section of circular pipe split along its axis. Both ends of the semi-circular connecting pipe 2-3 are connected to the tank truck connector 1 and the conveying pipeline respectively via flanges 4. A collection box 2-4 is provided at the bottom of the semi-circular connecting pipe. The collection box 2-4 includes a semi-circular pipe body, a rectangular box body, and a conical box body arranged sequentially from top to bottom. The semi-circular pipe body is connected to the semi-circular connecting pipe 2-3. The impact plate 2-1 is fixedly installed inside the rectangular box body. The impurity removal port 2-2 includes a blind plate detachably connected to the bottom of the conical box body via flanges 4.
[0025] In this embodiment, there are two impact plates 2-1, which are arranged in parallel inside the cuboid box. However, those skilled in the art should understand that the number of feed cylinders 2 can be selected according to specific working conditions and is not limited to two.
[0026] When the powder flow mixed with airflow enters the impurity collector 2 from the tank truck inlet 1, the flow velocity decreases sharply due to the rapid increase in cross-sectional area. Larger particles will naturally settle under gravity, achieving a collection effect. Furthermore, the powder flow mixed with airflow changes direction upon encountering the impact plate inside the impurity collector, guiding larger particles to the conical housing of the collection box for secondary collection. Based on the amount of large particles collected inside the conical housing of the collection box, operators can open the blind flange at the cleaning port as needed to discharge the collected large particles.
[0027] As can be seen from the above description, this utility model can effectively collect larger particulate impurities in powdered materials during the unloading and storage process of tank trucks, ensuring that the downstream weighing scale rotor is not blocked by foreign objects and thus preventing unplanned shutdowns caused by adjustment, thereby improving the reliability of operation.
[0028] The material conveying pipeline includes multiple straight feed pipes 5. Two feed pipes 5 located at both ends are connected to the semi-circular connecting pipe 2-3 and the feed end of the disperser 3 through flanges 4, respectively. Wear-resistant elbows 6 are provided between each pair of adjacent feed pipes 5 through flanges 4.
[0029] In this embodiment, all connection points use flange connections for easy installation, disassembly, and replacement of worn parts. However, those skilled in the art should understand that flange connections are used to facilitate subsequent installation, disassembly, and replacement; connection components other than flanges can be selected based on specific working conditions.
[0030] In this embodiment, there are four feed pipes 5 and three wear-resistant elbows 6. However, those skilled in the art should understand that the number is set according to the actual site conditions and can be selected based on specific working conditions. Furthermore, the inner diameter of each feed pipe 5 and each wear-resistant elbow 6 is [missing information]. 100, the preferred option is to use a hose with the same diameter as the tank truck's discharge port hose.
[0031] In this embodiment, the diameter of the semi-circular connecting pipe is the same as the diameter of the feed pipe, the width of the collection box is the same as the diameter of the feed pipe, and the height of the collection box is 5 times the diameter of the feed pipe. However, those skilled in the art should understand that the diameter of the semi-circular connecting pipe, the width of the collection box, and the height of the collection box can be selected according to specific working conditions and environmental space, and are not limited to the distance range disclosed in this utility model, with priority given to ensuring that the cross-sectional area along the feed inlet axis is more than 5 times the cross-sectional area of the feed pipe.
[0032] In this embodiment, the total length of the impurity remover, that is, the length of the semi-circular connecting pipe and the top of the collection box, is determined based on the movement trajectory of the material in the impurity remover. Preferably, it is between 80 and 100 cm. However, those skilled in the art should understand that the movement trajectory of the material in the impurity remover is determined by the air flow and the flow rate of the material flow entering the impurity remover box from the feed pipe; and the flow rate is affected by the air volume of the roots blower supporting the tanker and the cross-sectional area of the impurity remover. The total length of the impurity remover can be selected according to specific working conditions, and is not limited to the distance range disclosed in the present invention.
[0033] As Figures 5-7 shown, the disperser 3 includes an inlet pipe 3-2 and a reduced-diameter cone 3-3 which are connected in sequence from top to bottom. A plurality of the dispersing vanes 3-1 are fixedly arranged obliquely along the circumference in the reduced-diameter cone 3-3. The upper end of the inlet pipe 3-2 is connected to the corresponding feed pipe 5 through a flange 4. The reduced-diameter cone 3-3 includes a conical box 3-3-1 connected to the lower end of the inlet pipe 3-2 and having an inner diameter that gradually increases from top to bottom. The lower end of the conical box 3-3-1 is connected with a cylindrical box 3-3-2 for supporting and connecting the silo.
[0034] In addition, a support guide cone 3-4 is fixedly arranged in the middle of the reduced-diameter cone 3-3. The inner ends of the plurality of dispersing vanes 3-1 are fixedly connected to the outer peripheral wall of the support guide cone 3-4, and the outer ends of the plurality of dispersing vanes 3-1 are fixedly connected to the inner peripheral wall of the cylindrical box 3-3-2.
[0035] When the powder material flow mixed with the air flow enters the disperser from the feed pipe, under the combined action of the reduced-diameter cone 3-3 and the support guide cone 3-4, the air flow and the material flow are dispersed axially and are dispersed circumferentially under the action of the dispersing vanes 3-1, so that the powdery material enters the silo in a dispersed state, reducing the impact of the material on the metering equipment and maintaining the metering accuracy and stability, thereby maintaining the stable effect of the production system.
[0036] In this embodiment, the length of the inlet pipe is 50 cm. However, those skilled in the art should understand that the length of the inlet pipe is such that the disperser extends into the silo and can be selected according to specific working conditions;
[0037] In this embodiment, the upper diameter of the variable-diameter cone is 10cm, the lower diameter is 50cm, the height is 20cm, and the taper is 45°. However, those skilled in the art should understand that the upper diameter of the variable-diameter cone is designed to facilitate connection with the inlet pipe; the flow velocity of the airflow and material flow in the variable-diameter cone of the disperser is as slow as possible, and the flow velocity is affected by the air volume of the Roots blower matched with the tank truck and the cross-sectional area of the variable-diameter cone; the upper diameter, lower diameter, height, and taper of the variable-diameter cone can be selected according to the specific working conditions, and are not limited to the distance range disclosed in this utility model.
[0038] In this embodiment, there are 6 dispersing blades, which are at a 60° angle to the axis and a 60° angle to the horizontal plane. However, those skilled in the art should understand that the number of dispersing blades, the included angle, etc., can be selected according to the specific working conditions, and are not limited to the distance range disclosed in this utility model.
[0039] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
