Description

Technical Field

[0001] This utility model relates to the field of manufactured sand processing, and in particular to manufactured sand drying and humidification equipment. Background Technology

[0002] In the field of building materials production, manufactured sand, as an important aggregate for concrete and mortar, directly affects product quality due to the stability of its moisture content. Currently, manufactured sand requires drying during production to reduce its moisture content. However, traditional drying equipment mainly achieves sand dehydration through heat conduction or convection. This process tends to cause sand layers to accumulate during drying, with insufficient agitation between layers, leading to uneven heating. The upper layer of sand, due to sufficient heat contact, becomes over-dried, while the lower layer retains moisture due to poor flowability, severely impacting drying uniformity and energy efficiency.

[0003] Furthermore, manufactured sand may become too dry due to changes in ambient humidity during storage or transportation, which can easily cause dust or affect the accuracy of concrete mix proportions. Existing drying equipment typically only has a single drying function and cannot adjust humidification when the sand is too dry. Therefore, this solution proposes a manufactured sand drying and humidification system. Utility Model Content

[0004] The mechanical sand drying and humidification equipment proposed in this utility model solves the problems of inconvenient material turning and lack of humidification function in the existing technology during mechanical sand drying.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A manufactured sand drying and humidification device includes a drying tank, a feed hopper installed on the top of the drying tank, a hot air blower installed on the outer periphery of the drying tank for conveying hot air into it, and the interior of the drying tank containing:

[0007] The screening mechanism includes a screen installed inside the drying tank, a scraping assembly installed on the top of the drying tank, and a discharge pipe installed at the bottom of the screen. The top of the screen is provided with a discharge port communicating with the discharge pipe at a position offset from directly below the feed hopper. One end of the discharge pipe extends to the outside of the drying tank. The scraping assembly includes a rotating shaft rotatably connected to the top of the drying tank and a scraper fixed to the outer periphery of the rotating shaft. The bottom surface of the scraper abuts against the top surface of the screen.

[0008] A stirring mechanism is located below the screen. The stirring mechanism includes a stirring shaft inside the drying tank, multiple stirring rods fixed to the outer periphery of the stirring shaft, and a guide installed inside the drying tank for driving the stirring shaft to move up and down reciprocally when rotating. The top of the stirring shaft is movably connected to the rotating shaft and rotates synchronously with it when the rotating shaft rotates.

[0009] A humidification unit is installed inside the drying tank and is used to humidify the materials in the mixing tank.

[0010] The above technical solution not only facilitates screening of the manufactured sand before drying, but also allows for easy flipping of the bottom material to the top during drying, effectively improving drying efficiency. It also has a humidification function, making it convenient to humidify as needed.

[0011] As a further improvement to the above solution, the bottom of the rotating shaft extends to below the screen, and a buffer hole coaxially arranged with it is provided at the bottom of the rotating shaft. A limiting groove arranged along its axial direction is provided on the inner wall of the buffer hole. The top of the stirring shaft extends into the buffer hole and fits with it. A limiting block arranged along its axial direction is fixed on the outer periphery of the stirring shaft. One side of the limiting block extends into the limiting groove and slides with it.

[0012] As a further improvement to the above solution, the guide component includes a guide cylinder movably sleeved on the outer periphery of the stirring shaft and a guide post fixed on the outer periphery of the stirring shaft. The inner ring of the guide cylinder has a guide groove that is coaxially and inclined with it. One end of the guide post extends into the guide groove and slides with it. A fixing rod that is fixed to the bottom of the discharge pipe is fixed on the outer periphery of the guide cylinder.

[0013] As a further improvement to the above solution, the humidification mechanism includes an annular pipe sleeved around the outer periphery of the guide tube and multiple water spray pipes fixed around the outer periphery of the annular pipe and communicating with its interior. Multiple nozzles are installed on the bottom surface of the water spray pipes. A water supply pipe is installed on the annular pipe, one end of which extends to the outside of the drying tank, and a valve is installed on the water supply pipe.

[0014] As a further improvement to the above solution, the bottom of the drying tank is provided with a discharge port, and a baffle mechanism for blocking the discharge port is installed at the bottom of the drying tank. The baffle mechanism includes an adjusting handle rotatably connected to the outer periphery of the drying tank and a baffle plate fixed to the bottom of the adjusting handle for blocking the discharge port.

[0015] As a further improvement to the above solution, the stirring rod is a regular triangular prism structure, and the top surface of the stirring rod is horizontal.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a screening mechanism, it is easy to remove the unqualified particles in the manufactured sand, thereby reducing the subsequent screening process and improving production efficiency.

[0018] 2. By setting up a stirring mechanism, the manufactured sand in the drying tank can be stirred horizontally and moved from the lower part of the drying tank to the upper part, thereby facilitating the turning of materials and helping to speed up the drying process.

[0019] 3. By setting up a humidification mechanism, water mist can be sprayed into the drying tank when it is necessary to humidify the manufactured sand. Combined with the stirring mechanism, this achieves the purpose of conveniently and evenly humidifying the manufactured sand. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1:

[0031] Please combine Figures 1-7 The manufactured sand drying and humidification equipment of this embodiment includes a drying tank 1, a feeding hopper 2 installed on the top of the drying tank 1, and a hot air blower 4 for conveying hot air into the drying tank 1 installed on the outer periphery of the drying tank 1. The manufactured sand to be dried is fed into the drying tank 1 through the feeding hopper 2, and then the hot air blower 4 is started to convey hot air into the drying tank 1, thereby drying the manufactured sand in the drying tank 1.

[0032] Drying tank 1 is equipped with:

[0033] The screening mechanism includes a screen 6 installed inside the drying tank 1, a scraping assembly installed on the top of the drying tank 1, and a discharge pipe 12 installed at the bottom of the screen 6. A discharge port 13, communicating with the discharge pipe 12, is located at the top of the screen 6, offset from directly below the feed hopper 2. One end of the discharge pipe 12 extends to the outside of the drying tank 1. The scraping assembly includes a rotating shaft 14 rotatably connected to the top of the drying tank 1 and a scraper 7 fixed to the outer periphery of the rotating shaft 14. The bottom surface of the scraper 7 abuts against the top surface of the screen 6. A transmission mechanism for driving the rotating shaft 14 is installed on the top surface of the drying tank 1. The output shaft of motor 3 is connected to the top of rotating shaft 14. After the manufactured sand enters the drying tank 1 from the feed hopper 2, it falls on the top surface of screen 6. After the drive motor 3 rotates, it can drive the rotating shaft 14 to rotate. After the rotating shaft 14 rotates, it can drive the manufactured sand falling on the top surface of screen 6 to move and flatten along its surface, so that the part of the manufactured sand that meets the particle size falls below screen 6, while the unqualified part with a larger particle size will eventually fall into the discharge port 13 under the drive of scraper 7, and then be discharged from the discharge pipe 12, thereby achieving the purpose of convenient screening of manufactured sand.

[0034] The stirring mechanism, located below the screen 6, includes a stirring shaft 16 inside the drying tank 1, multiple stirring rods 11 fixed to the outer periphery of the stirring shaft 16, and guide members installed inside the drying tank 1 to drive the stirring shaft 16 to reciprocate up and down during rotation. The top of the stirring shaft 16 is movably connected to the rotating shaft 14 and rotates synchronously with it when the rotating shaft 14 rotates. The bottom of the rotating shaft 14 extends below the screen 6, and a buffer hole coaxially arranged with it is opened at the bottom of the rotating shaft 14. A limiting groove 19 arranged along its axial direction is opened on the inner wall of the buffer hole. The top of the stirring shaft 16 extends into the buffer hole and fits into it. A guide member is fixed along its axial direction on the outer periphery of the stirring shaft 16. The limiting block 18 is set in the directional direction, and one side of the limiting block 18 extends into the limiting groove 19 and slides with it. The setting of the limiting groove 19 and the limiting block 18 allows the stirring shaft 16 to not only move along the axial direction of the rotating shaft 14, but also to rotate synchronously with the rotating shaft 14. Thus, driven by the rotating shaft 14, the stirring shaft 16 can drive the stirring rod 11 to stir the manufactured sand in the drying tank 1, thereby accelerating the drying efficiency of the manufactured sand. The setting of the guide component can drive the stirring shaft 16 to move up and down reciprocally during the rotation of the stirring shaft 16, thereby gradually turning the manufactured sand at the bottom of the drying tank 1 to the upper layer, greatly improving the drying efficiency of the manufactured sand.

[0035] The guide component includes a guide cylinder 15 movably sleeved on the outer periphery of the mixing shaft 16 and a guide post 21 fixed on the outer periphery of the mixing shaft 16. The inner ring of the guide cylinder 15 has a guide groove 20 coaxially and inclinedly arranged therewith. One end of the guide post 21 extends into the guide groove 20 and slides therewith. A fixing rod fixed to the bottom of the discharge pipe 12 is fixed on the outer periphery of the guide cylinder 15. While the mixing shaft 16 rotates, the guide cylinder 15 remains stationary, and the guide post 21 rotates synchronously with the mixing shaft 16. When rotating, the guide post 21 slides along the guide groove 20, so that while rotating with the mixing shaft 16, it can drive the mixing shaft 16 to move up and down reciprocally in the inclined direction of the guide groove 20, thereby facilitating the up and down reciprocating movement of the mixing rod 11 while rotating, and thus facilitating the up and down turning of the manufactured sand.

[0036] In this embodiment, the stirring rod 11 is a regular triangular prism structure, and the top surface of the stirring rod 11 is horizontal. When the top surface of the stirring rod 11 is horizontal, one edge of the stirring rod 11 is located at the bottom, which can reduce the resistance when the stirring rod 11 descends. The horizontal top surface can drive more manufactured sand to move upward when the stirring rod 11 rises, thereby improving the effect of tumbling the manufactured sand.

[0037] In this embodiment, the bottom of the drying tank 1 is provided with a discharge port, and a baffle mechanism for blocking the discharge port is installed at the bottom of the drying tank 1. The baffle mechanism includes an adjusting handle 9 rotatably connected to the outer periphery of the drying tank 1 and a baffle plate 8 fixed to the bottom of the adjusting handle 9 for blocking the discharge port. Rotating the adjusting handle 9 can drive the baffle plate 8 to rotate. After the baffle plate 8 gradually deviates from the discharge port, the manufactured sand in the drying tank 1 can be discharged from the discharge port.

[0038] Example 2:

[0039] Combination Figure 2 , Figure 4 and Figure 5 This embodiment, based on embodiment 1, further improves upon the following: it also includes a humidification mechanism, which is installed inside the drying tank 1 and used to humidify the material in the mixing chamber. The humidification mechanism includes an annular pipe 17 sleeved around the outer periphery of the guide cylinder 15 and multiple water spray pipes 10 fixed around the outer periphery of the annular pipe 17 and communicating with its interior. Multiple nozzles are installed on the bottom surface of the water spray pipes 10. A water supply pipe 5 is installed on the annular pipe 17. One end of the water supply pipe 5 extends to the outside of the drying tank 1, and a valve is installed on the water supply pipe 5. When it is necessary to humidify the manufactured sand, the water supply pipe 5 can be connected to an external water pipe first, and then the valve can be opened. Water enters the annular pipe 17 and then enters the interior of the multiple water spray pipes 10 respectively. Finally, it is sprayed out from the nozzles onto the manufactured sand, thereby humidifying the manufactured sand.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
