Description

Technical Field

[0001] This utility model relates to the field of concrete production and processing, and in particular to an additive feeding device for concrete production. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. Concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] In the concrete production process of related technologies, aggregates and water are separately injected into a mixing tank, and then the aggregates and water are mixed by a mixer inside the tank to produce concrete. Depending on the specific needs, liquid additives such as coagulants and antifreeze agents are usually added to the mixing tank to improve the performance of the concrete.

[0004] In related technologies, when adding concrete additives, workers connect the feeding pipe to the injection pipe at the top of the mixing tank, and then add the additive into the mixing tank through the feeding pipe. However, the additive is injected into the mixing tank at a specific angle, which prevents it from making extensive contact with the raw materials. The raw materials and additives need to be mixed for a long time to be fully mixed, thus affecting production efficiency and requiring improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an additive feeding device for concrete production, which enables the additive to come into contact with the raw materials over a wide range, facilitating rapid and thorough mixing of the raw materials and the additive, thereby improving production efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concrete production additive feeding device, comprising:

[0007] Support base, used for connecting to the filling pipe at the top of the mixing tank;

[0008] The feeding pipe is vertically fixed on the support base. The feeding pipe can pass through the injection pipe and allow the bottom of the feeding pipe to enter the mixing tank.

[0009] A conveying mechanism, connected to the top of the feeding pipe, is used to convey the additive into the feeding pipe;

[0010] A spray pipe is coaxially connected to the bottom of the feeding pipe;

[0011] A spray ball is fixed to the bottom of the spray pipe. The spray ball has a spray chamber inside, and the spray chamber is connected to the spray pipe.

[0012] Multiple spray nozzles are fixedly connected to the bottom of the spray ball. The multiple spray nozzles are arranged in a matrix and are respectively arranged along the radial direction of the spray ball.

[0013] Optionally: the spray pipe and the feeding pipe are rotatably connected by a sealed bearing, and the spray pipe is provided with a control component, which is used to control the rotation of the spray pipe.

[0014] Optionally, the control component includes a control plate fixed to the inner wall of the spray pipe. The control plate is spirally arranged and can drive the spray pipe to rotate under the action of the additive fluid.

[0015] Optionally: the bottom of the support base is provided with an annular mounting groove, the top of the filling tube can be tightly inserted into the mounting groove, and the support base is provided with a limiting member for fixing the filling tube.

[0016] Optionally, the limiting component includes a plurality of limiting screws that are threadedly connected to the support base. The plurality of limiting screws are arranged at equal intervals along the circumference of the filling tube. The ends of the plurality of limiting screws that are far apart from each other are respectively fixedly connected to a control handwheel, and the ends that are close to each other are respectively used to press against the filling tube.

[0017] Optionally: The conveying mechanism includes a vertically arranged conveying pipe, a conveying pump connected to the conveying pipe, the bottom of the conveying pipe being fixedly connected to the feeding pipe, and a quick connector being fixedly connected to the top of the conveying pipe, and the quick connector being used to connect to an external additive pipeline.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 A concrete additive feeding device includes a support base 1, which is connected to a filling pipe at the top of a mixing tank. A feeding pipe 2 is vertically fixed to the support base 1, allowing the feeding pipe 2 to pass through the filling pipe and its bottom to enter the mixing tank. Simultaneously, a conveying mechanism 3 is connected to the top of the feeding pipe 2, which conveys the additive into the feeding pipe 2.

[0027] Reference Figure 1 , Figure 3 A spray pipe 4 is coaxially connected to the bottom of the feeding pipe 2. A spray ball 5 is fixedly connected to the bottom of the spray pipe 4. The spray ball 5 has a spray chamber 6 inside, and the spray chamber 6 is connected to the spray pipe 4. At the same time, multiple spray nozzles 7 are fixedly connected to the bottom of the spray ball 5. The multiple spray nozzles 7 are arranged in a matrix and are respectively arranged along the radial direction of the spray ball 5, so that the additive can be sprayed in multiple directions in the mixing tank.

[0028] The spray ball 5, spray nozzle 7, and feeding pipe 2 are passed through the filling pipe and then into the mixing tank. The support base 1 is then connected to the filling pipe. Subsequently, the additive is conveyed to the feeding pipe 2 by the conveying mechanism 3. At this time, the additive enters the spray chamber 6 through the spray pipe 4 and is sprayed into the mixing tank through multiple spray nozzles 7.

[0029] The additive feeding device in this embodiment allows the additive to be sprayed in multiple directions within the mixing tank, increasing the spraying range of the additive and enabling it to come into contact with the raw materials over a wide area. This facilitates rapid and thorough mixing of the additive and the raw materials, thereby improving production efficiency.

[0030] Reference Figure 1 , Figure 3The spray pipe 4 and the feeding pipe 2 are rotatably connected via a sealed bearing. A control element 8 is installed on the spray pipe 4 to control its rotation. The control element 8 includes a control plate 81 fixed to the inner wall of the spray pipe 4. The control plate 81 is spirally arranged. When the additive flows through the control plate 81, the control plate 81 can drive the spray pipe 4 to rotate under the fluid action of the additive. At this time, the spray nozzles 7 and multiple spray nozzles 7 rotate synchronously with the spray pipe 4 to expand the spray range of the additive and facilitate contact between the additive and the raw material.

[0031] Reference Figure 1 , Figure 3 The support base 1 has an annular mounting groove 9 at its bottom, into which the top of the filling tube can be tightly inserted. The support base 1 also has a limiting member 10 for fixing the filling tube. The limiting member 10 includes multiple limiting screws 101 threaded onto the support base 1. These screws are evenly spaced along the circumference of the filling tube. A control handwheel 102 is fixedly connected to the ends of the screws 101 that are far apart from each other, and the ends that are close together are used to press against the filling tube.

[0032] Reference Figure 1 , Figure 2 The conveying mechanism 3 includes a vertically arranged conveying pipe 31, a conveying pump 32 connected to the conveying pipe 31, a quick connector 33 fixedly connected to the bottom of the conveying pipe 31 and the top of the conveying pipe 31, and the quick connector 33 is used to connect to an external additive pipeline. At the same time, a flow meter 34 is connected to the conveying pipe 31 to monitor the amount of additive used.
