Description

Technical Field

[0001] This utility model relates to the field of mortar preparation, and in particular to a drying device for the production of dry-mixed premixed mortar. Background Technology

[0002] Dry-mixed mortar refers to a granular or powdery material made by physically mixing dried and screened aggregates, inorganic cementitious materials, and additives in a certain proportion. It is transported to the construction site in bagged or bulk form and can be used directly after mixing with water. To prevent moisture in the aggregates from caking with the cementitious materials during transportation, the aggregates must first be treated to ensure dryness before being proportioned and uniformly mixed to form a semi-finished mortar product. Adding water and stirring completes the mortar for use. When storing and transporting mortar, it is often necessary to dry it first.

[0003] Most improvements to mortar drying devices in the prior art focus on increasing drying efficiency. Chinese patent document CN217560258U discloses a premixed mortar drying device that solves the problems in the prior art where mortar easily clumps during the drying process, resulting in poor drying effect and the inability to screen excessively large raw materials. Furthermore, the mixing of uncrushed clumps with the mortar leads to unsatisfactory mortar performance. The main technical solution is to add a stirring mechanism, with the first stirring mechanism and the second stirring mechanism alternately arranged to fully stir the mortar. The heating mechanism then heats and dries the mortar, achieving the purpose of full stirring and thus realizing the technical effects of complete stirring and improved drying efficiency.

[0004] While the above-mentioned devices have certain advantages in improving drying efficiency, they still have some shortcomings:

[0005] The above-mentioned device can only achieve the drying effect. The mortar needs to be cooled before it can be put into production. The mortar after drying by the above-mentioned device needs to be cooled separately. Therefore, the integration of the above-mentioned device is low. Several devices are needed to completely dry the mortar, which is inconvenient to operate. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a drying device for the production of dry-mixed premixed mortar.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a drying device for dry-mixed premixed mortar production, comprising a drying mechanism, a cooling mechanism, and a control mechanism. The drying mechanism and the cooling mechanism are connected via a conveying mechanism. Two sets of control mechanisms are provided, each set located inside the drying mechanism and the cooling mechanism. The drying mechanism includes a drying chamber, a cover plate, a feed hopper, a first discharge port, a first stirring mechanism, and a heating device. A cover plate is provided on the top of the drying chamber, and the cover plate is detachably connected to the drying chamber. A feed hopper is located on the top of the cover plate. A first discharge port is located at the bottom of the drying chamber. The drying chamber contains... The first stirring mechanism includes a heating device installed on the inner wall of the drying chamber; the cooling mechanism includes a cooling chamber, a feed inlet, an output motor, fan blades, a second stirring mechanism, a second discharge outlet, a discharge pipe, and a baffle. A feed inlet is located on one side of the cooling chamber, and a first output motor is placed at the top of the cooling chamber. The output end of the output motor is connected to fan blades. A second stirring mechanism is installed inside the cooling chamber, and a second discharge outlet is located at the bottom of the cooling chamber. The second discharge outlet is connected to a discharge pipe, and a baffle is inserted into the discharge pipe. The two sets of control mechanisms include a temperature sensor and a PLC controller, with the temperature sensor electrically connected to the PLC controller.

[0008] As a further embodiment of this utility model, a set of temperature sensors is installed inside the drying oven, and a set of PLC controllers is installed outside the drying oven. The PLC controllers are electrically connected to the heating device. This set of control mechanisms is used to control the drying mechanism. Through the cooperation of the PLC controllers and temperature sensors, the temperature inside the drying oven can be obtained in a timely manner, thereby adjusting the heating device through the PLC controllers.

[0009] As a further embodiment of this utility model, a set of temperature sensors is installed inside the cooling box, and a set of PLC controllers is installed outside the cooling box. The PLC controllers are electrically connected to the first output motor. This set of control mechanisms is used to control the cooling mechanism. Through the cooperation of the PLC controllers and temperature sensors, the temperature inside the cooling box can be obtained in a timely manner, thereby observing the cooling effect of the mortar raw materials, and stopping the fan blades from working through the PLC controllers.

[0010] As a further embodiment of this utility model, the first stirring mechanism includes a first drive motor, a first output shaft, and a first stirring blade. The first drive motor is connected to the first output shaft via a coupling. Multiple sets of first stirring blades are fixedly connected to the outer surface of the first output shaft. The first stirring mechanism is used to fully stir the mortar raw materials so that the mortar raw materials can be fully dried.

[0011] As a further embodiment of this utility model, the second stirring mechanism includes a second drive motor, a second output shaft, and a second stirring blade. The second drive motor is connected to the second output shaft via a coupling. Multiple sets of second stirring blades are fixedly connected to the outer surface of the second output shaft. The second stirring mechanism is used to stir the dried mortar raw material in the cooling box so that the mortar raw material can dissipate heat fully.

[0012] As a further embodiment of this utility model, the conveying mechanism includes a conveying pipe, a third drive motor, a third output shaft, and a conveying auger. The conveying pipe connects the first discharge port and the inlet port. The conveying pipe is horizontally positioned, and the third drive motor is placed on top of the conveying pipe. The third drive motor is connected to the third output shaft via a coupling. The outer surface of the third output shaft is provided with a conveying auger. The conveying channel is used to convey the mortar raw material that has been dried in the drying device to the cooling box. Since the conveying pipe is horizontally positioned, the mortar raw material will not automatically slide into the cooling box. Therefore, the conveying speed of the raw mortar can be controlled by controlling the rotation speed of the conveying auger to ensure that the mortar raw material in the drying box can be fully dried.

[0013] As a further embodiment of this utility model, a vent is provided on the side of the cooling box. The vent is used to exhaust the high-temperature air inside the cooling box to the outside. More preferably, some mesh shields can be installed on the vent to prevent the mortar raw materials from overflowing.

[0015] This invention incorporates a drying mechanism and a cooling mechanism. The drying mechanism dries the mortar raw materials, while the stirring mechanism ensures thorough drying. The cooling mechanism allows the high-temperature mortar to dissipate heat before use, improving production efficiency. Furthermore, the control mechanism monitors the internal temperatures of both the drying and cooling mechanisms and adjusts the internal temperatures via a PLC controller, thereby regulating drying or cooling efficiency. This design offers excellent integration and greater controllability. Attached Figure Description

The user can observe the temperature inside the controlled drying box 11 through the PLC controller 32. After the mortar material is fully dried, the user starts the third drive motor 42 to drive the conveying auger 44 to rotate and transport the dried mortar material to the cooling box 21. At this time, the user starts the output motor 23 through the PLC controller 32 to drive the fan blade 24 to rotate. The user can observe the temperature inside the cooling box 21 at any time through the PLC controller 32. After the mortar is fully cooled, the user removes the baffle 28, and the mortar material is output outward due to its own gravity.
