Description

Technical Field

[0001] This utility model relates to the field of concrete batching plant technology, specifically to a batching plant device without a mixing host. Background Technology

[0002] A concrete batching plant is a machine and equipment that mixes cement, aggregates (including sand and stone), water, and dry materials in a certain proportion and then loads them onto transport equipment.

[0003] The current common practices for concrete mix design include:

[0004] 1. In small-scale construction projects, on-site drum mixers are often used for mixing, but the proportions are not precise enough, resulting in unstable concrete quality;

[0005] 2. Using a small commercial concrete mixing plant results in relatively high equipment costs and large total power due to the use of a twin-shaft main unit. It also requires a separate transformer, leading to a large investment. Utility Model Content

[0006] The purpose of this invention is to provide a batching station device without a mixing host to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a batching station device without a mixing host, comprising a three-hopper batching machine and a main building frame. A belt conveyor is installed at the bottom discharge port of the three-hopper batching machine. A cement silo, a cement metering hopper, and a collection hopper are fixedly installed in the main building frame from top to bottom. The discharge end of the belt conveyor is located above the inlet of the collection hopper. The discharge port of the cement silo is connected to the inlet of the cement metering hopper. The discharge port of the cement metering hopper is located directly above the inlet of the collection hopper. A control room is provided in front of the belt conveyor.

[0008] Preferably, each bucket of the three-bucket batching machine is equipped with four pressure sensors at the bottom, and the four pressure sensors form a scale. Each bucket is also equipped with a pneumatic discharge gate at the bottom, which is located above the belt conveyor. Each bucket is also equipped with an audible and visual alarm.

[0009] Preferably, the discharge ports at the bottom of the cement silo, cement metering hopper, and aggregate hopper are equipped with pneumatic butterfly valves.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This mixerless batching station device mixes all materials inside a mixing tanker truck after all materials have been fed in. This allows for simultaneous mixing and transportation, saving energy and producing qualified concrete. The tanker truck then delivers the concrete to the construction site. This device is primarily used in urban construction projects requiring small quantities of concrete. By installing a mixerless batching station in a relatively small area, sand, gravel, powder, and water are proportioned and uniformly added to the mixing tanker truck. The mixing tanker truck replaces the mixing action of the conventional mixing plant's main mixer, achieving low investment and rapid production, while maintaining concrete quality comparable to conventional commercial concrete plants.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-2 This utility model provides a technical solution: a batching station device without a mixing host, including a three-hopper batching machine 1, a belt conveyor 2, a cement silo 3, a cement metering hopper 4, a collection hopper 5, a control room 6, and a main building frame 7. The belt conveyor 2 is installed at the bottom discharge port of the three-hopper batching machine 1. The cement silo 3, the cement metering hopper 4, and the collection hopper 5 are fixedly installed in the main building frame 7 from top to bottom. The discharge end of the belt conveyor 2 is located above the inlet of the collection hopper 5. The discharge port of the cement silo 3 is connected to the inlet of the cement metering hopper 4. The discharge port of the cement metering hopper 4 is located directly above the inlet of the collection hopper 5. The control room 6 is located in front of the belt conveyor 2.

[0017] Furthermore, each bucket of the three-bucket batching machine 1 is equipped with four pressure sensors at the bottom, and each bucket is also equipped with a pneumatic discharge gate at the bottom, which is located above the belt conveyor 2. Each bucket is also equipped with a fixed audible and visual alarm.

[0018] Through the above technical solution, four pressure sensors form a scale. The pressure sensors and the audible and visual alarm are electrically connected to the control device in the control room 6. The pressure sensors weigh the material in each hopper. During the feeding process, each hopper is discharged individually, and the weight of the discharged material is measured by subtraction. The pneumatic discharge door is controlled by a cylinder to open and close. The audible and visual alarm is electrically connected to the control device in the control room 6. When the material in the hopper is lower than the set value, an audible and visual alarm is issued to remind the staff to add material.

[0019] Furthermore, pneumatic butterfly valves are installed at the discharge ports at the bottom of cement silo 3, cement metering hopper 4, and aggregate hopper 5.

[0020] The above technical solution uses pneumatic butterfly valves to control the opening and closing of the discharge ports of cement silo 3, cement metering hopper 4, and collection hopper 5.

[0021] Working Principle: First, the three-bucket batching machine 1 uses a subtraction weighing method. After the loader fills each bucket, each bucket is equipped with four pressure sensors to form a scale. Each scale has a pneumatic discharge gate at the bottom, below which is the belt conveyor 2. When the equipment is in production, according to the set formula, the pneumatic discharge gates of the corresponding buckets are opened sequentially to discharge material. When the set value is reached, the pneumatic discharge gates are closed. The three weighing buckets cannot weigh simultaneously to prevent material spillage from the belt conveyor 2. Each bucket of the belt conveyor 2 has an audible and visual alarm function. When the weight in the bucket is lower than the set value, the audible and visual alarm sounds to remind the staff to add material. When it is higher than the set value, the audible and visual alarm does not give any indication. The required sand and gravel, after being subtractively weighed, enters the collection hopper 5 through the belt conveyor 2 and is then directly fed into the tanker truck. At the same time, the pneumatic butterfly valve connected to the discharge port of the cement silo 3 above the main building frame 7 is opened, and the cement falls into the cement metering hopper 4 for further processing. Metering is also performed using a pressure sensor. Once metering is complete, the pneumatic butterfly valve at the discharge port of cement silo 3 closes, and the pneumatic butterfly valve at the discharge port of cement metering 4 opens, allowing the cement to be fed into the mixing tanker through the collection hopper 5. Water is controlled by a water pump and a vortex flow meter on the pipeline to control the total amount of water. The water outlet is installed at the feed hopper position of the mixing tanker. The control system is installed in the control room 6. Once all materials have been fed into the mixing tanker, all raw materials are mixed inside the tanker. This allows for mixing and transportation simultaneously, saving energy and producing qualified concrete. The mixing tanker is then delivered to the construction site. This device is mainly used in urban construction where a small amount of concrete is required. By installing a batching station without a mixing host in a smaller area, sand, gravel, powder, and water are proportioned and uniformly fed into the mixing tanker. The mixing tanker replaces the mixing host in a conventional mixing plant, achieving the goal of low investment and rapid production, while producing concrete of the same quality as a conventional commercial concrete plant.

[0022] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
