Description

Technical Field

[0001] The invention relates to the technical field of concrete production and processing, in particular to a rapid feeding device for concrete production. Background Art

[0002] With the development of the construction industry and the transportation industry, the solution of ready-mixed concrete has been widely used. Ready-mixed concrete refers to a concrete mixture of cement, aggregate, water and additives added as needed in a certain proportion, which is sold after being measured and mixed at a mixing station and transported to the place of use within a specified time by a transport vehicle. In this way, the concrete is centrally mixed, which is conducive to the use of advanced process technology, the implementation of professional production management, high equipment utilization rate, accurate measurement, and the prepared dry materials are put into the concrete mixer for full mixing, and then loaded into the concrete mixer truck. Therefore, the product quality is good, the material consumption is small, the work efficiency is high, the cost is low, and the working conditions can be improved and the environmental pollution can be reduced.

[0003] In the concrete production process, the input ratio and sequence of raw materials have a crucial impact on the quality of concrete. At the same time, there are requirements for the mixing rate of raw materials. They need to be mixed at a constant rate. Mixing too fast or too slow will lead to a decrease in the quality of concrete, which leads to low concrete production efficiency. Because the mixing speed is constant, in order to improve production efficiency, it can only be done through other methods, such as increasing the feeding rate and reducing the feeding time. However, if all the raw materials are poured in at once, the mixing unevenness of the raw materials will increase, which will lead to an increase in mixing time. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please refer to the attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a rapid feeding device for concrete production, comprising:

[0033] A mixing hopper 2 is arranged above the feed inlet of the mixer 1, and the discharge end of the mixing hopper 2 is sunk into the feed inlet of the mixer 1. The mixing hopper 2 is used to premix the production raw materials and evenly spread the production raw materials in the mixer 1;

[0034] The transverse vibration frame 3 is used to support and fix the mixing hopper 2, and drive the mixing hopper 2 to perform transverse reciprocating motion on a horizontal plane;

[0035] Aggregate conveying device, used to quantitatively convey aggregate raw materials into the mixing hopper 2;

[0036] A raw material sand conveying device is used to quantitatively convey the sand raw material into the mixing hopper 2;

[0037] A cement conveying device, used for quantitatively conveying cement into the mixing hopper 2;

[0038] An additive injection device, used to quantitatively inject additives for concrete production into the mixing hopper 2;

[0039] The water injection device is used to quantitatively inject concrete production water into the mixing hopper 2.

[0040] Through the coordination of the aggregate conveying device, the raw material sand conveying device, the cement conveying device, the additive injection device and the water injection device, the quantitative input of the raw materials is realized, and the accuracy of the raw material ratio is improved. At the same time, through the setting of the mixing hopper 2, the raw materials put into it are preliminarily premixed, and the raw materials are evenly spread in the mixer 1, thereby improving the uniformity of the raw materials before mixing, thereby improving the mixing efficiency. At the same time, through the setting of the horizontal vibration frame 3, the mixing hopper 2 is driven to perform horizontal reciprocating motion in the horizontal plane, which greatly increases the feeding area of ​​the mixing hopper 2, thereby further improving the feeding uniformity and further improving the mixing efficiency. At the same time, the mixing hopper 2 also drives the movement of the raw materials inside it during the reciprocating movement, thereby increasing the rate of raw material leakage and avoiding the situation of raw material blockage.

[0041] The transverse vibration frame 3 includes a frame body 301, the bottom of which is fixedly connected to the base of the mixer 1, and the top is slidably connected to the outer wall of the mixing hopper 2. A reciprocating cylinder 302 is fixedly connected to the top wall of the frame body 301, and the output end of the reciprocating cylinder 302 is fixedly connected to the outer wall of the mixing hopper 2, which is used to drive the mixing hopper 2 to slide transversely reciprocatingly along the top of the frame body 301.

[0042] The mixing hopper 2 is driven by the reciprocating cylinder 302 to slide horizontally and reciprocatingly along the top of the frame 301. On the one hand, the raw materials are affected by inertia and the mixing hopper 2, which greatly increases the spreading area when put into the mixer 1. On the other hand, the raw materials move and vibrate synchronously with the reciprocating motion of the mixing hopper 2, thereby increasing the rate of raw material leakage and avoiding raw material blockage.

[0043] The mixing hopper 2 includes two symmetrically arranged outer shells 4, a plurality of parallel Y-shaped cylinders 5 are arranged below the two outer shells 4, and a gap 6 is arranged between two adjacent Y-shaped cylinders 5. The outer shell 4 adopts a bucket-shaped structure, and the outer shell 4 is opened and connected at the top and bottom. The two feed ports at the top of the Y-shaped cylinder 5 are respectively connected with the lower openings of the two outer shells 4. The two outer shells 4 are respectively used to inject aggregates, sand raw materials and cement. A groove 7 is formed between the two outer shells 4, and the groove 7 is connected with the gap 6 for injecting water and additives.

[0044] It should be noted that the injection site of water and additives is separated from raw materials such as cement to avoid adhesion of cement and other materials with water, which may cause the cement and other materials to adhere to or clog the mixing hopper 2 .

[0045] By utilizing the structure of the Y-shaped cylinder 5, the aggregate, sand raw materials and cement are preliminarily mixed at the lower part of the Y-shaped cylinder 5 after being injected, thereby achieving the effect of premixing. The Y-shaped cylinder 5 is provided in multiple parts, that is, the raw materials entering the outer shell 4 are divided into multiple parts, so as to reduce the amount of each raw material in each mixing process, thereby avoiding exceeding the mixing capacity of the Y-shaped cylinder 5 due to excessive mixing raw materials, so as to further improve the mixing effect. Water and additives are injected into the groove 7, and then dispersed into the mixer 1 through multiple gaps 6 to improve the uniformity of the input of the two raw materials.

[0046] A flow dividing block 8 is arranged at the inner center intersection of the Y-shaped cylinder 5, and the flow dividing block 8 is a columnar structure with a triangular cross section.

[0047] By setting the diverter block 8, on the one hand, the raw materials are diverted again into the mixer 1 under the action of the diverter block 8 to improve the uniformity in a dispersed form, and at the same time, the mobility of the raw materials at the diverter block 8 is accelerated, thereby improving the mixing effect.

[0048] A plurality of diverter plates 9 are evenly arranged from top to bottom in the gap 6 .

[0049] The gap 6 is divided into multiple channels by multiple evenly arranged diverter plates 9, so that the water or additives are further dispersed. With the reciprocating lateral movement of the mixing hopper 2, the water or additives fall out from multiple channels, further expanding the spreading area, increasing the contact area with other raw materials in the mixing hopper 2, and improving the mixing efficiency.

[0050] The aggregate conveying device includes an aggregate box 10, and a Z-type belt conveyor 11 is arranged between the aggregate box 10 and the mixing hopper 2. The bottom feeding end of the Z-type belt conveyor 11 is located in the aggregate box 10, and the top discharging end of the Z-type belt conveyor 11 is located above the opening on the outer shell 4. The aggregate box 10 and the Z-type belt conveyor 11 are fixedly connected to the weighing end of the weighing device 12.

[0051] The configured aggregate is poured into the aggregate box 10, and the weighing device 12 is used to detect the overall weight of the aggregate box 10, the Z-belt conveyor 11 and the aggregate in real time. The aggregate is lifted from the aggregate box 10 by the Z-belt conveyor 11 and input into the mixing hopper 2. During this process, the aggregate is continuously separated from the aggregate conveying device, and the only weight change is the reduction of the aggregate, and this reduction can be obtained by subtracting the current weight from the initial weight, thereby realizing real-time detection of the aggregate feeding amount.

[0052] The raw material sand conveying device includes an auger conveyor 13, and a storage hopper 14 is arranged at the bottom feed port of the auger conveyor 13. The storage hopper 14 is used to store sand raw materials. The top discharge port of the auger conveyor 13 is located above the opening on the outer shell 4. The auger conveyor 13 and the storage hopper 14 are fixedly connected to the weighing end of the weighing device 15.

[0053] Similarly, the sand raw material is stored in a storage hopper 14, and a weighing device 15 is used to detect the overall weight of the auger conveyor 13, the storage hopper 14 and the sand raw material in real time. The sand raw material in the storage hopper 14 is input into the mixing hopper 2 through the auger conveyor 13. During this process, the sand raw material continuously separates from the raw material sand conveying device, and the only weight change is the reduction of the sand raw material, and this reduction can be obtained by subtracting the current weight from the initial weight, thereby realizing real-time detection of the sand raw material feeding amount.

[0054] The cement conveying device includes an auger conveyor 16, and a storage hopper 17 is arranged at the bottom feed port of the auger conveyor 16. The storage hopper 17 is used to store cement raw materials. The top discharge port of the auger conveyor 16 is located above the opening on the outer shell 4. The auger conveyor 16 and the storage hopper 17 are fixedly connected to the weighing end of the weighing device 18.

[0055] Similar to the raw material sand conveying device, the cement raw material is stored in the storage hopper 2 17, and the weighing device 3 18 is used to detect the overall weight of the auger conveyor 2 16, the storage hopper 2 17 and the cement raw material in real time. The sand raw material in the storage hopper 2 17 is input into the mixing hopper 2 through the auger conveyor 2 16. In this process, the cement raw material is continuously separated from the cement conveying device, and the only weight change is the reduction of the cement raw material, and this reduction can be obtained by subtracting the current weight from the initial weight, thereby realizing the real-time detection of the cement raw material feeding amount.

[0056] The additive injection device comprises a pneumatic conveying device, which is used for quantitatively conveying the additive. The discharge port of the conveying pipeline 19 of the pneumatic conveying device is located in the groove 7.

[0057] The pneumatic conveying device can realize the function of quantitatively conveying materials. Under its function, the additives are put into the mixing hopper 2 through the conveying pipe 19 and quantitative delivery is realized at the same time.

[0058] The water injection device comprises a water injection pipe 20, one end of which is located in the groove 7, and the other end of which is connected to the output end of a water injection pump, and the water injection pump is used for quantitatively conveying water.

[0059] A flow detector is provided in the water injection pump device, which detects the amount of water flowing through in real time, thereby realizing the function of the water injection pump to quantitatively transport water. Through its function, water is quantitatively input into the mixing hopper 2 through the water injection pipe 20.

[0060] It should be noted that the specific amount of the above-mentioned quantitative amount is pre-calculated and set according to the specifications and quantity of concrete. At the same time, the order of input of each raw material is also preset according to the production process to ensure the production quality of concrete.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
