Description

Technical Field

[0001] This utility model relates to the field of metering device technology, and in particular to an automatic feeding and metering system for non-fired bricks. Background Technology

[0002] The main way to utilize waste core materials from door products (such as fire doors) is to use these waste core materials to prepare various new building materials, such as non-fired bricks. The method of preparing non-fired bricks from waste core materials mainly involves processing the waste core materials through crushing, screening, and magnetic separation, then mixing them with natural sand and gravel, fly ash, etc., and pressing them with a brick-making machine to produce non-fired bricks.

[0003] When mixing ingredients, it is necessary to strictly measure each raw material according to the proportion. The existing material measurement of non-fired bricks is through a weighing belt (i.e., belt scale), such as the patent with publication number CN214562002U. The weighing belt has the following disadvantages: firstly, its measurement accuracy is poor; secondly, when measuring multi-component materials, multiple sets of conveyor belts need to be set up, which will occupy a large amount of production space. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic feeding and metering system for non-fired bricks. By setting multiple metering components, it can realize the simultaneous metering and proportioning of multi-component materials. The system occupies little space and improves the space utilization of the production site.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic feeding and metering system for non-fired bricks includes a frame and at least two metering components mounted on the frame. Each metering component includes a metering box and multiple weighing sensors. The metering box has a material inlet and a material outlet, and the material outlet is equipped with a valve for controlling the opening and closing of the material outlet.

[0007] Multiple weighing sensors are mounted on the frame, and the metering box is provided with multiple support seats corresponding to each weighing sensor. The metering box is supported by the weighing sensors through the support seats.

[0008] Furthermore, the load cell is fixedly mounted on the frame, and the load cell's feet are mounted on a support base.

[0009] Furthermore, four metering components are provided, which are used for metering core material, aggregate, water and cement respectively;

[0010] A metering component for measuring core material, water, and cement has a metering box with a narrowed bottom forming a cylindrical material outlet. The material outlet is connected to a circular pipe. The valve includes a circular valve plate adapted to fit inside the circular pipe. The circular valve plate is connected to a rotating shaft, which is rotatably connected to the circular pipe. One end of the rotating shaft extends out of the circular pipe and is connected to a motor drive.

[0011] Furthermore, the circular tube is connected to the material outlet via a flange.

[0012] Furthermore, the metering component used for cement metering has its metering box's material outlet connected to the vibrating screen's material inlet.

[0013] Furthermore, the metering component for aggregate metering has a rectangular material outlet at the bottom of its metering box. The valve includes a rectangular baffle located at the material outlet and larger than the material outlet. The rectangular baffle is driven by a reciprocating telescopic member to move horizontally to open or close the material outlet.

[0014] Furthermore, the reciprocating telescopic component is a pneumatic cylinder or a hydraulic cylinder.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1-7 This utility model provides a technical solution:

[0027] Example:

[0028] like Figures 1-7 As shown, an automatic feeding and metering system for non-fired bricks includes a frame 1 and at least two metering components mounted on the frame 1. The metering components include a metering box 2 and multiple weighing sensors 3. The metering box 2 has a material inlet and a material outlet, and the material outlet is equipped with a valve for controlling the opening and closing of the material outlet.

[0029] Multiple weighing sensors 3 are mounted on the frame 1, and the metering box 2 is provided with multiple support seats 4 corresponding to the weighing sensors 3 one by one. The metering box 2 is supported by the weighing sensors 3 through the support seats 4.

[0030] The load cell 3 is fixedly mounted on the frame, and its support legs are mounted on the support base 4. The load cell 3 is an SQB load cell 3.

[0031] The metering components are set up in four parts, which are used for metering core material, aggregate, water and cement respectively;

[0032] The metering assembly for measuring core material, water, and cement has a metering box 2 with a narrowed bottom forming a cylindrical material outlet. The material outlet is connected to a circular pipe 5. The valve includes a circular valve plate 6 fitted inside the circular pipe 5. The circular valve plate 6 is connected to a rotating shaft 7, which is rotatably connected to the circular pipe 5 (and the axis of the rotating shaft 7 is radially parallel to the circular valve plate 6). One end of the rotating shaft 7 extends out of the circular pipe 5 and is connected to a motor 8 for transmission.

[0033] The circular pipe 5 is connected to the material outlet via a flange.

[0034] The metering assembly used for cement metering has its metering box 2 connected to the material inlet of the vibrating screen 9.

[0035] like Figure 2 and Figure 7 As shown, the metering component for aggregate metering has a rectangular material outlet at the bottom of its metering box 2. The valve includes a rectangular baffle 10 located at the material outlet and larger than the material outlet. The rectangular baffle 10 is driven by a reciprocating telescopic member 11 (a cylinder in this embodiment) to move horizontally to open or close the material outlet.

[0036] 1. A metering component for aggregate metering, comprising a metering box 2 with a rectangular ring plate welded to the bottom, two symmetrical slide rails on the ring plate, a rectangular baffle 10 slidably disposed within the slide rails, a connecting strip at the end of the baffle, and two parallel cylinders on both sides of the ring plate, the piston rods of the cylinders connected to the connecting strips, the piston rods being parallel to the length direction of the slide rails. 2. A lower-level metering component for aggregate metering. 3. A support base 4 comprising an L-shaped support plate, the support plate being connected to the side wall of the metering box 2 and the sensor's support feet, the support plate having right-angled trapezoidal reinforcing ribs on both sides. 4. Four support bases 4 symmetrically disposed on opposite sides of the metering box 2.

[0037] Working principle: The raw materials for non-fired bricks (core material, water, cement, aggregate (crushed stone, etc.)) are weighed and measured by four metering components to meet the mixing ratio requirements and then sent to the mixing tank below for mixing.

[0038] Core material, water, and cement are fed into metering tank 2 through their respective metering component inlets. Once the weight detected by weighing sensor 3 reaches the set weight, the conveying mechanism (such as a hoist or water pump) is stopped (this control can be achieved via PLC; the control process is existing technology and will not be detailed here). Simultaneously, the valve is opened to deliver the metered material to the mixing tank. The valve opening process involves motor 8 rotating, causing the circular valve plate 6 to rotate from horizontal to vertical. At this point, the material outlet connects to the mixing tank below, and the material automatically enters the mixing tank under gravity.

[0039] When cement is fed, the interaction between molecules will affect the feeding speed because it is a powder. Therefore, the vibration generated by the vibrating screen 9 will speed up the feeding speed of cement.

[0040] Aggregates enter the metering box 2, which is used to measure aggregates, through the material inlet. The metering process is as described above. When the metering is completed, the valve of the metering box 2 opens as follows: the cylinder piston rod extends, driving the baffle to move horizontally until the baffle no longer blocks the material outlet (the mixing tank is equipped with a feed hopper with a size larger than the material outlet). At this time, the aggregates fall into the mixing tank automatically under the action of gravity, and then the mixing and blending of raw materials can begin.

[0041] This invention enables simultaneous metering and proportioning of multi-component materials by setting up multiple metering components, with a small overall footprint, thus improving the space utilization of the production site; at the same time, the use of a vibrating screen improves the feeding of cement.

[0042] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
