Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a multi-stage filtration feeding mechanism for the production of concrete admixtures. Background Technology

[0002] Concrete admixtures are chemical substances added during concrete mixing, accounting for less than 5% of the cement mass, and can significantly improve concrete performance. Concrete admixtures are characterized by a wide variety, small dosage, and significant impact on concrete performance, enhancing the economy and mixability of concrete and meeting various engineering construction needs. During their processing, a feeding machine is typically used to feed raw materials. The raw materials in the feeding machine are conveyed into the processing equipment via a transfer component. However, existing feeding machines only have storage bins and transfer components, lacking devices for screening and pre-treatment of raw materials. This results in variations in the particle size of the raw materials entering the bins. These materials are directly conveyed to the processing equipment. Excessive particle size variation not only affects the subsequent mixing effect of the admixture but may also lead to uneven distribution of the admixture in the concrete, affecting the overall quality of the concrete. Furthermore, when the raw materials contain large particles or impurities, it can easily cause blockages in the feeding channel, thus affecting production efficiency. Utility Model Content

[0020] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0021] Example 1

[0022] A multi-stage filtration and feeding mechanism for concrete admixture production, such as Figure 1-6As shown, the system includes a main support frame 1, a hopper, a spring 3, a cylinder 41, a cylinder cover 42, a discharge pipe 43, a vibration module 44, a filter screen 45, a spiral conveyor 5, a transmission component 51, and a discharge pipe 52. A receiving hopper 2 is installed on the left side of the main support frame 1. The top of the hopper is elastically connected to the filter cylinder via a spring 3. This elastic connection provides the filter cylinder with a buffer space when subjected to material impact or vibration, reducing the risk of damage from rigid connections. It also helps the filter cylinder to better vibrate and screen materials when connected to vibrating components. The filter cylinder consists of multiple stacked cylinders 41 and a cylinder cover 42 installed on the topmost cylinder 41. A feed inlet is located on the top of the cylinder cover 42, and a feed pipe is installed at the feed inlet for material input. Discharge pipes 43 are connected to the tangent of the lower edge of the cylinder 41. The discharge pipes 43 are connected to the internal space of the cylinder 41. Filter screens 45 are installed in the lower part of the cylinder 41. The end of the discharge pipe 43 that connects to the internal space of the cylinder 41 is at the same height as the filter screen 45 inside the cylinder 41. Large particles blocked by the filter screen 45 can be discharged in a timely manner through the discharge pipe 43 along the tangent of the inner wall of the cylinder 41, so as to avoid the accumulation of large particles in the cylinder 41 and affect the filtration effect. Vibration modules 44 are installed on the left and right sides of the bottom layer of the filter cylinder 41. The vibration generated by the vibration module 44 when it is working is transmitted to the filter cylinder. Under the action of shaking, the material on the filter screen 45 is driven to complete the filtration process faster.

[0023] A spiral conveyor 5 is connected to the lower part of the receiving hopper 2. The spiral conveyor 5 consists of a conveyor pipe and spiral blades that are rotated and installed inside the conveyor pipe. A conveyor port is opened at the connection between the receiving hopper 2 and the conveyor pipe, allowing the material in the receiving hopper 2 to enter the conveyor pipe through the conveyor port. After filtration, the material can smoothly enter the conveyor pipe of the spiral conveyor 5 from the receiving hopper 2. The conveyor pipe is inclined from left to right, and its right side is connected to the main support frame 1 for stable support. The spiral conveyor 5 conveys material... A transmission component 51 is installed on the right side of the pipe. The transmission component 51 drives the spiral blades of the spiral conveyor 5 to rotate, which conveys the material falling into the conveyor pipe to the right. The cooperation between the transmission component 51 and the spiral blades realizes the stable and continuous transmission of materials, ensuring the smooth operation of the production process. The lower right part of the spiral conveyor 5 is connected to the discharge pipe 52, which is connected to the internal space of the conveyor pipe. The material transmitted by the spiral conveyor 5 is finally discharged from the discharge pipe 52, completing the entire feeding and filtering transmission process.

[0024] Specifically, a multi-layer filter screen 45 is set up in layers. The material fed into the cylinder cover 42 is filtered through the multi-layer filter screen 45. The multi-layer filter screen 45 can gradually intercept large particles of different sizes, achieving a finer filtration effect. Finally, the material falls into the receiving hopper 2, and then is efficiently transported to the next production stage through the spiral conveyor 5. This multi-stage filtration and efficient transmission design effectively improves the purity of the materials used in the production of concrete admixtures, reduces the impact of impurities on subsequent production, and improves production quality and efficiency.

[0025] Example 2

[0026] Based on Example 1, such as Figure 1 , Figure 3 and Figure 4 As shown, it also includes a valve body 6 and a backflush pipe 61. The valve body 6 is connected to the discharge pipe 52, and the backflush pipe 61 is connected to the valve body 6. The other end of the backflush pipe 61 is inserted into the discharge pipe 52. The valve body 6 controls the backflush airflow to spray from the backflush pipe 61 to the inner wall of the discharge pipe 52. The airflow impact force blows off the material adhering to the pipe wall in time, preventing material accumulation and blockage, ensuring the continuous unobstructed flow of the internal channel of the discharge pipe 52, and avoiding residual material from affecting the uniformity of subsequent feeding.

[0027] like Figure 1 As shown, it also includes a vibration module 2 7. The lower left part of the conveying pipe of the spiral conveyor 5 is connected to the vibration module 2 7. The vibration module 2 7 acts on the wall of the conveying pipe near the conveying port through high-frequency vibration, so that the material in the receiving hopper 2 falls evenly at the conveying port, avoiding local adhesion or accumulation caused by material moisture or static electricity, and ensuring that the material enters the spiral conveyor 5 for transmission stably.

[0028] Among them, such as Figure 2 , Figure 5 and Figure 6 As shown, it also includes a feed hopper 8, a cyclone component 81, an air inlet pipe 82, and a fan blade 83. The feed hopper 8 is provided at the feed inlet of the cylinder cover 42. The feed hopper 8 has a discharge port at the bottom and is connected to the cylinder body 41. The cyclone component 81 is vertically installed inside the feed hopper 8. The fan blade 83 is installed on the cyclone component 81 and is driven to rotate by an external power. The air inlet pipe 82 on one side of the lower part of the cyclone component 81 extends upward and passes through the cylinder cover 42. The air inlet pipe 82 introduces external airflow into the feed hopper 8, which, together with the rotating fan blade 83, forms a vortex airflow. As the material falls into the feed hopper 8, it is dispersed by both airflow and mechanical force, effectively separating agglomerated particles, reducing material clumping into the filter cylinder, and improving the filtration efficiency of the filter screen 45.

[0029] In addition, such as Figure 1As shown, it also includes a receiving pipe 9 and a hose 91. The receiving pipe 9 is vertically installed on one side of the upper part of the receiving hopper 2. The ends of the discharge pipes 43 are all connected to the receiving pipe 9 through the hose 91. The impurity particles discharged from the discharge pipes 43 are flexibly guided into the receiving pipe 9 through the hose 91 and collected. The bending adaptability of the hose 91 reduces the difficulty of alignment between multiple discharge pipes 43 and receiving pipes 9, and avoids the risk of vibration transmission or interface leakage caused by hard connection.

[0030] In a preferred embodiment: such as Figure 1 and Figure 3 As shown, it also includes rollers 10. Rollers 10 are symmetrically provided on both the front and rear sides of the lower part of the main support frame 1. The rollers 10 are fixed to the bottom of the main support frame 1 through brackets, providing support and steering functions for the overall movement of the equipment, making it easy to flexibly adjust the position of the equipment according to production needs. At the same time, locking components should be provided on the rollers 10 so that the rollers 10 can be locked when the equipment is placed stably, to prevent accidental displacement during operation.

[0031] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
