Description

Technical Field

[0001] This utility model relates to concrete production equipment, and in particular to a low-temperature production system for ready-mixed concrete. Background Technology

[0002] Taiwan Patent No. 483812 discloses a manufacturing method for reducing the temperature of concrete. It uses cold air generated by a cooler to cool the storage tank, thereby achieving zero wastewater and sludge discharge. However, various raw materials (such as sand, gravel, or other materials such as additives) carry a large amount of heat energy when stored in the storage tank from the outside. Therefore, the cooler may need to operate at high power to efficiently reduce the temperature of the raw materials.

[0003] Furthermore, during the mixing process, the friction between various raw materials generates heat, which in turn generates and accumulates heat during the mixing process, which is not conducive to the production of low-temperature concrete.

[0004] In addition, various raw materials will still contain moisture when stored from the outside to the storage tank, meaning that the raw materials in the storage tank are not completely dry, which will affect the quality of the concrete material after the mixing process. Utility Model Content

[0005] In view of the above deficiencies, the premixed concrete low-temperature production system of this utility model can not only effectively reduce the temperature of various raw materials, but also adjust the amount of water supplied during the mixing process according to the humidity of each material, so as to improve the quality of concrete materials.

[0006] To achieve the above objectives, the premixed concrete low-temperature production system of this utility model includes multiple storage tanks, a cooling device, a conveying device, a mixing device, and a control device. Each storage tank includes a tank body, a temperature sensing module, and a humidity sensing module. The tank body is used to store a raw material and has a feeding channel for supplying the raw material. The supplied raw material is defined as a pre-mixed raw material. The temperature sensing module and the humidity sensing module are disposed within the tank body. The temperature sensing module is used to sense the temperature within the tank body to generate a temperature signal. The humidity sensing module is used to sense the humidity of the raw material to generate a humidity signal. The cooling device is connected to the tank bodies of the multiple storage tanks and is used to cool the temperature within the tank bodies of the multiple storage tanks. The conveying device is disposed at relative positions to the multiple storage tanks and includes multiple weighing scales and a conveyor belt. Multiple pre-mixed raw materials supplied from the feeding channels of the tank bodies of the multiple storage tanks generate corresponding weight signals through the multiple weighing scales. The conveyor belt is used to transport the multiple pre-mixed raw materials passing through the multiple weighing scales. The mixing device is connected to the conveyor belt of the conveying device to receive the multiple pre-mixed raw materials and add water to mix them into a concrete material. The control device connects to temperature and humidity sensing modules in multiple storage tanks, multiple scales in the conveying equipment, and mixing equipment to control the cooling equipment based on the multiple temperature signals. It also has a concrete formula corresponding to the concrete materials. The control device confirms the weight of multiple raw materials based on the concrete formula and multiple weight signals, and adjusts the water volume based on multiple humidity signals.

[0007] Thus, the premixed concrete low-temperature production system of this utility model can obtain the required amount of each raw material by controlling the concrete formula of the equipment, and obtain the moisture content of each raw material by the humidity signal generated by the humidity sensing module, so as to adjust the amount of water added by the mixing equipment during the mixing process, so as to make the concrete material closer to the concrete formula and achieve automated production.

[0008] The detailed structure and features of the premixed concrete low-temperature production system provided by this invention will be described in the subsequent detailed description of the embodiments. However, those skilled in the art should understand that this detailed description and the specific embodiments listed for implementing this invention are only for illustrating this invention and are not intended to limit the scope of patent protection of this invention.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0037] like Figure 1As shown, the premixed concrete low-temperature production system 100 of this utility model includes multiple storage tanks 10, a cooling device 20, a conveying device 30, a mixing device 40, and a control device 50. In this embodiment, the number of storage tanks 10 is five; in other embodiments, the number of storage tanks may be two, three, four, six, or more. Generally, a material temperature below 32 degrees Celsius during the premixed concrete production process is considered low-temperature production.

[0038] In this embodiment, the storage tanks 10 are arranged horizontally, but in other embodiments, the multiple storage tanks 10 may also be cylindrical or configured as other separate storage tanks. Each storage tank 10 includes a tank body 11, a temperature sensing module 13, a humidity sensing module 15, and a scanning module 17. The tank body 11 is used to store raw materials, and each tank body 11 stores a corresponding raw material, such as sand 61, large gravel 62, small gravel 63, cement 64, and additives 65. The tank body 11 has a feeding channel 111 for supplying raw materials. The supplied raw materials are defined as a set of preparatory raw materials 611, 631, 641, and 651. Since each storage tank 10 supplies a corresponding raw material, when two or more storage tanks 10 are supplying preparatory raw materials, there will be two or more types of preparatory raw materials.

[0039] Temperature sensing module 13, humidity sensing module 15, and scanning module 17 are disposed within tank 11. Although the corresponding graphics and positions within the other four tanks 11 in the figure are not labeled, it can still be understood that similar positions and graphics represent temperature sensing module 13, humidity sensing module 15, and scanning module 17. Temperature sensing module 13 is used to sense the temperature within tank 11 to generate a temperature signal. Humidity sensing module 15 is used to sense the humidity of the raw materials to generate a humidity signal. Scanning module 17 is used to detect the inventory of raw materials to generate an inventory signal. Scanning module 17, such as a level sensor, image sensor, or scanner, is used to detect the liquid level position of the raw materials inside tank 11. In this embodiment, temperature sensing module 13 and scanning module 17 are located near the top of tank 11, which is away from the feeding channel 111. Temperature sensing module 13 is used to reflect the temperature within tank 11, and humidity sensing module 15 is located near the feeding channel 111 of tank 11 to reflect the moisture content of the raw materials, which is beneficial to the quality of the produced concrete materials.

[0040] The cooling device 20 is connected to the tank bodies 11 of five storage tanks 10 and is used to cool the temperature inside the tank bodies 11 of the five storage tanks 10. The arrows inside each tank body 11 in the figure indicate the direction of cold air flow. In this embodiment, the cooling device 20 includes a liquid cooling device 21 and five heat dissipation devices 23. The liquid cooling device 21 can also be called a water cooling device.

[0041] The liquid cooling device 21 is connected to the tank 11 of five storage tanks 10 to maintain the temperature of the tanks 11 of the five storage tanks 10 at a refrigeration temperature controlled by the control device 50 through cryogenic liquid cooling. In this embodiment, the liquid cooling device 21 includes a main unit (not shown in the figure), a liquid cooling water tank 211, a gas pipe 213, and a water pipe 215. The main unit is used to cool the liquid (usually water) in the liquid cooling water tank 211 to keep the liquid in a cryogenic liquid state. The gas pipe 213 is connected to the liquid cooling water tank 211 to collect cold air from the liquid cooling water tank 211 and deliver the cold air to the five tanks 11.

[0042] Five heat dissipation devices 23 are connected to the top of the tank 11 of the five storage tanks 10, and are configured one-to-one. In this embodiment, the heat dissipation device 23 is an exhaust fan to exhaust the gas inside the tank 11 to the outside. In other embodiments, if the tops of the five tanks 11 are connected, the number of heat dissipation devices 23 can be one, two, three, four or more.

[0043] The conveying device 30 is positioned relative to the five storage tanks 10 and includes five scales 31 and a conveyor belt 33. Multiple raw materials supplied from the feed channels 111 of the tank bodies 11 of the five storage tanks 10 generate corresponding weight signals through the five scales 31. The conveyor belt 33 is used to transport the multiple raw materials passing through the scales 31. In this embodiment, the feed channels 111 of the tank bodies 11 of the five storage tanks and the five scales 31 are arranged along the conveyor belt 33 of the conveying device 30.

[0044] The mixing equipment 40 is connected to the conveyor belt 33 of the conveying equipment 30 to receive multiple prepared raw materials and add water to mix them into a concrete material. The mixing equipment 40 is connected to the water pipe 215 of the liquid cooling device 21 so that the water added to the mixing equipment 40 includes the low-temperature liquid supplied by the water pipe 215.

[0045] The control device 50 is connected to the temperature sensing module 13 and humidity sensing module 15 of the tank bodies 11 of five storage tanks 10, the scanning module 17, the five scales 31 of the conveying device 30, and the mixing device 40. It controls the cooling device 20 based on five temperature signals and has a concrete formula corresponding to the concrete materials. The control device 50 confirms the weight of multiple raw materials based on the concrete formula and multiple weight signals, and adjusts the water volume based on multiple humidity signals. The concrete formula changes according to the application requirements of the concrete materials.

[0046] The control device 50, such as a computer or other computing device, obtains the ambient temperature inside the tank 11 through the temperature signals from each temperature sensing module 13. When one or all of the multiple temperature signals received by the control device 50 correspond to a temperature higher than the refrigeration temperature, it indicates that the ambient temperature inside any or all of the tanks 11 is higher than the refrigeration temperature of the control device 50. The control device 50 then activates the corresponding heat dissipation device 23 to expel heat. At this time, the liquid cooling device 21 continues to supply cold air to each tank 11. In this way, the heat dissipation efficiency inside the tank 11 can be improved through the action of cold air and exhaust, achieving an energy-saving effect. Subsequently, when the multiple temperature signals received by the control device 50 correspond to a temperature lower than the refrigeration temperature, it indicates that the ambient temperature inside all of the tanks 11 is lower than the refrigeration temperature of the control device 50. The control device 50 then pauses the corresponding heat dissipation device 23. Pausing means stopping the exhaust fan of the heat dissipation device 23 or reducing its speed.

[0047] The control device 50 has a display 51 for displaying an inventory status based on five inventory signals, so that the operator can see from the display 51 whether the raw materials in each tank 11 are sufficient, for example, if the inventory of small gravel 63 is low and needs to be replenished.

[0048] During the production of ready-mixed concrete, the control equipment 50 supplies the corresponding pre-mixed raw materials to the tanks 11 of each storage tank 10 according to the concrete formula (including selected raw material types, weight parameters, and water content parameters). At this time, the control equipment 50 can obtain the weight of each pre-mixed raw material through the weight signals of each scale 31, and obtain the humidity or moisture content of each pre-mixed raw material through the humidity signal of the humidity sensing module 15. Subsequently, when the weight of the pre-mixed raw material is confirmed to match the weight of the concrete formula, the control conveyor belt 33 transports each pre-mixed raw material to the mixing equipment 40, and adjusts the amount of water added according to the humidity of each pre-mixed raw material. When the overall humidity of the pre-mixed raw materials is high, the amount of water added can be reduced; conversely, when the overall humidity of the pre-mixed raw materials is low, the amount of water added can be increased to meet the water content parameters in the concrete formula.

[0049] Furthermore, because the added water is a low-temperature liquid, the concrete material will remain at a low temperature to maintain its quality. Finally, the concrete material is supplied to concrete truck 70.

However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of the present invention is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of the present invention, and all such substitutions and modifications should fall within the scope of the present invention.
