Description

Technical Field

[0001] This utility model relates to a dry powder mortar drying device, and more particularly to a drying device for dry powder mortar. Background Technology

[0002] Dry mortar refers to a granular or powdery material made by physically mixing aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion after drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water. It is also known as dry mortar powder, dry-mixed mortar, or dry-mixed powder. Some building adhesives also belong to this category. Dry mortar plays a role in bonding, padding, protection, and decoration in the construction industry by applying thin layers. It is widely used in building and decoration projects. Dry mortar requires drying treatment during the production process.

[0003] Chinese Patent CN216924917U discloses a dry powder mortar drying device, including a drying box. The top of the drying box has two baking chambers, and a stirring chamber is located below the baking chambers. The top of the baking chambers is equipped with a baking lamp, and the bottom of the baking chambers is equipped with a base plate. The base plate has an outlet, and two sliding plates are provided at the outlet, which are slidably connected to the base plate on both sides of the outlet. The base plate has a sliding groove that cooperates with the sliding plates to slide. Push rods extending out of the drying box are provided on both sides of the sliding plates.

[0004] However, the above-mentioned patents have the following shortcomings:

[0005] The aforementioned patent uses a vibrating feeder and a mixing rod to break up aggregates and inorganic cementitious materials, and then uses a heating rod to dry the heated materials. However, the water vapor generated during the drying process cannot be quickly discharged, resulting in a humid environment inside the device, which in turn reduces the drying efficiency of the device. Utility Model Content

[0006] This utility model provides a drying device for dry powder mortar, aiming to solve the problem of a drying device for dry powder mortar mentioned in the background art.

[0007] This utility model is implemented as follows: a drying device for dry powder mortar includes a drying chamber, a feeding chamber at the top of the drying chamber, a discharging chamber at the bottom of the drying chamber, a rotating disk rotatably arranged inside the drying chamber, and a drying mechanism between the rotating disk and the drying chamber. The drying mechanism is used to uniformly dry the material in the drying chamber.

[0008] The drying mechanism includes a stepper motor, a first barrier net, a connecting groove, and an air inlet pipe. The side wall of the stepper motor is fixedly connected to the drying chamber, and the output shaft of the stepper motor is fixedly connected to the rotating disk. The first barrier net is disposed on the outer periphery of the drying chamber.

[0009] The connecting groove is formed on the outer periphery of the rotating disk, and the number of the connecting groove is set to multiple.

[0010] The connecting trough has an air inlet hole on its side wall, a second barrier net is fixedly connected to the inner wall of the connecting trough, a partition plate is fixedly connected to one side of the top of the connecting trough, the side wall of the partition plate is fixedly connected to the outer periphery of the rotating disk, and the outer periphery of the partition plate abuts against the inner wall of the drying chamber.

[0011] The end of the air inlet pipe extends through the drying chamber, and the end of the air inlet pipe is matched with multiple air inlet holes;

[0012] Each pair of partitions between the rotating disc and the drying chamber can be combined with the rotating disc and the drying chamber to form a compartment, and each compartment has a connecting groove that is connected to this compartment through a second barrier net.

[0013] Therefore, when the wet material enters the drying chamber through the feeding hopper, as the stepper motor drives the rotating disk to rotate, the wet material can fall into multiple chambers in sequence. The stepper motor will drive the rotating disk to rotate intermittently, so that the chambers on the outer periphery of the rotating disk correspond to the positions of the first barrier net on the surface of the drying chamber in sequence.

[0014] When the position of this chamber corresponds to the position of the first barrier net, the position of the air inlet on the side wall of the connecting channel corresponding to this chamber will correspond to the end of the air inlet pipe. At this time, the hot air can be pumped into the air inlet pipe through the external air heating pumping equipment, and after entering the connecting chamber through the air inlet, it will pass through the second barrier net, pass through the bottom of the material and be discharged through the first barrier net. In this way, the hot air can fully contact the material and the generated moisture will be discharged through the first barrier net.

[0015] Then, when the chamber rotates to the position corresponding to the discharge chamber, the material will be discharged through the discharge chamber under the action of gravity.

[0016] Preferably, the partition plate has a groove on its outer periphery, and a sealing strip is provided inside the groove. The sealing strip is made of rubber material.

[0017] By installing a sealing strip around the outer perimeter of the partition plate, the airtightness between the partition plate and the drying chamber can be improved, thereby preventing hot air from leaking out through the gap between the partition plate and the drying chamber.

[0018] Preferably, the top of the feed hopper is provided with a guide chamber, which is flared.

[0019] By setting an flared guide compartment at the top of the feed hopper, materials can be easily placed into the feed hopper.

[0020] Preferably, the end of the air inlet pipe is provided with an annular groove, and a sealing ring is provided inside the annular groove, the sealing ring being made of rubber material;

[0021] By installing a sealing ring at the end of the air inlet pipe, the airtightness between the end of the air inlet pipe and the rotating disk can be increased, thereby preventing hot air from leaking out through the gap between the hot air pipe and the rotating disk.

[0022] Preferably, a support frame is fixedly connected to the bottom of the drying chamber, and the bottom of the support frame is provided with an anti-slip pad;

[0023] By installing anti-slip pads at the bottom of the support frame, the stability of the device when placed on the surface can be improved.

[0024] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a drying device for dry powder mortar.

[0025] By setting up a drying structure, a large amount of material can be divided into multiple chambers, allowing hot air to fully and evenly contact the material, thereby improving the drying effect. The humid air generated during drying can be quickly discharged, and the device can continuously dry the material without repeatedly adding and removing it manually, thus improving the drying efficiency of the device.

[0040] Please see Figure 1-5 This utility model provides a technical solution: a drying device for dry powder mortar, including a drying chamber 1, a feeding chamber 11 at the top of the drying chamber 1, a discharging chamber 12 at the bottom of the drying chamber 1, a rotating disk 13 rotatably arranged inside the drying chamber 1, and a drying mechanism 2 between the rotating disk 13 and the drying chamber 1, the drying mechanism 2 being used to uniformly dry the material in the drying chamber 1.

[0041] The drying mechanism 2 includes a stepper motor 21, a first barrier net 22, a connecting groove 23 and an air inlet pipe 24. The side wall of the stepper motor 21 is fixedly connected to the drying chamber 1, and the output shaft of the stepper motor 21 is fixedly connected to the rotating disk 13. The first barrier net 22 is arranged on the outer periphery of the drying chamber 1.

[0042] The connecting groove 23 is formed on the outer periphery of the rotating disk 13, and the number of connecting grooves 23 is set to multiple;

[0043] The connecting trough 23 has an air inlet 25 on its side wall, and a second barrier net 26 is fixedly connected to the inner wall of the connecting trough 23. A partition plate 27 is fixedly connected to one side of the top of the connecting trough 23.

[0044] The end of the air inlet pipe 24 passes through the drying chamber 1, and the end of the air inlet pipe 24 is matched with multiple air inlet holes 25.

[0045] Furthermore, the partition plate 27 has a groove 3 on its outer periphery, and a sealing strip 4 is provided inside the groove 3. The sealing strip 4 is made of rubber material.

[0046] Furthermore, a guide chamber 5 is provided at the top of the feed hopper 11, and the guide chamber 5 is designed to be flared.

[0047] Furthermore, the end of the air inlet pipe 24 is provided with an annular groove 6, and a sealing ring 7 is provided inside the annular groove 6. The sealing ring 7 is made of rubber material.

[0049] Working principle and usage process of this utility model:

[0050] Each pair of partition plates 27 between the rotating disk 13 and the drying chamber 1 can be combined with the rotating disk 13 and the drying chamber 1 to form a chamber, and each of them has a connecting groove 23 connected to this chamber through the second barrier net 26.

[0051] Therefore, when the wet material enters the drying chamber 1 through the feeding hopper 11, as the stepper motor 21 drives the rotating disk 13 to rotate, the wet material can fall into multiple chambers in sequence. The stepper motor 21 will drive the rotating disk 13 to rotate intermittently, so that the chambers on the outer periphery of the rotating disk 13 correspond to the positions of the first barrier net 22 on the surface of the drying chamber 1 in sequence.

[0052] When the position of this chamber corresponds to the position of the first barrier net 22, the position of the air inlet 25 on the side wall of the connecting groove 23 corresponding to this chamber will correspond to the end of the air inlet pipe 24. At this time, through the external air heating pumping equipment, hot air can be pumped into the air inlet pipe through the air inlet pipe, and after entering the connecting chamber through the air inlet 25, it will pass through the second barrier net 26, pass through the bottom of the material and be discharged through the first barrier net 22. In the above way, the hot air can fully contact the material and the generated moisture can be discharged through the first barrier net 22.

[0053] Then, when the chamber rotates to the position corresponding to the position of the discharge chamber 12, the material will be discharged through the discharge chamber 12 under the action of gravity.
