[0002] A dry-mixed mortar production line is an automated production system that produces uniform dry powder premixed mortar by accurately measuring dry aggregates, cement, and various functional admixtures according to a scientific formula and then using an efficient mixing process.

[0003] If natural river sand is used in a dry-mixed mortar production line, the high moisture content of the natural river sand will cause the finished mortar to easily clump, affecting storage time and construction performance. Therefore, drying equipment is needed to dry the sand to ensure mortar quality and production stability.

[0004] The existing publicly available technical solution, CN215337485U, discloses a drying drum for a premixed dry mortar production line, which includes a dry drum body and a door panel hinged to the side of the dry drum body away from the outer shell. The cement and sand can be removed by opening the door panel.

[0005] In actual implementation, the above technical solution involves opening the side door panel for material discharge. Workers need to manually pull open the side door panel and get close to the high-temperature drying drum body. If the protective measures are insufficient, burns can easily occur. Summary of the Invention

[0006] The purpose of this utility model is to provide a high-efficiency drying equipment for dry-mixed mortar production lines.

Detailed Implementation

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A high-efficiency drying equipment for dry-mixed mortar production line includes a drying cylinder 1, a cover assembly 2 installed at one end of the drying cylinder 1, and a feeding trough 6 for feeding is connected to the top of the drying cylinder 1. A drying assembly 3 is provided on the side of the feeding trough 6, an angle adjustment assembly 4 is provided at the bottom of the drying cylinder 1, and a sealing cover is provided on the top of the feeding trough 6. After feeding is completed, the sealing cover seals the feeding trough 6.

[0029] The cover assembly 2 includes a drying cylinder cover 201 that is slidably disposed on the side of the drying cylinder 1. A high-temperature resistant sealing ring is provided between the drying cylinder 1 and the drying cylinder cover 201. A scraper 205 is fixed on the surface of the drying cylinder cover 201 facing the drying cylinder 1, and a connecting rod 204 is provided between the scraper 205 and the drying cylinder cover 201. The outer side of the scraper 205 is in contact with the inner wall of the drying cylinder 1.

[0030] The angle adjustment component 4 includes a base 402 disposed at the bottom of the drying cylinder 1, and a second hydraulic cylinder 401 is rotatably connected between the base 402 and the drying cylinder 1.

[0031] The cover assembly 2 also includes guide rods 202 disposed on the left and right sides of the drying cylinder cover 201. The ends of the guide rods 202 are fixed to the left and right sides of the drying cylinder 1. Fixing members 203 are welded around the drying cylinder cover 201. The guide rods 202 pass through the interior of the fixing members 203. A first hydraulic cylinder 206 is bolted to the top of the drying cylinder 1, and the telescopic end of the first hydraulic cylinder 206 is fixedly connected to the fixing member 203.

[0032] The angle adjustment assembly 4 also includes a support member 403 disposed on the top of the base 402. The support member 403 is internally connected to a first connecting column 404 fixed to the bottom of the drying cylinder 1. The angle adjustment assembly 4 also includes a second connecting column 405 rotatably connected to both ends of the second hydraulic cylinder 401. The second connecting column 405 is respectively installed at the bottom of the drying cylinder 1 and the side of the base 402. The second connecting column 405 passes through the connecting members at both ends of the second hydraulic cylinder 401, so that when the second hydraulic cylinder 401 is working, it pushes one end of the drying cylinder 1 to rotate.

[0033] By adopting the above technical solution, during material discharge, the second hydraulic cylinder 401 is first activated, pushing the end of the drying cylinder 1 away from the drying cylinder cover 201 to rotate upward. At this time, the height of the drying cylinder cover 201 is relatively low, and the sand inside the drying cylinder 1 moves towards the drying cylinder cover 201 under the action of gravity. Then, the first hydraulic cylinder 206 is activated, pushing the drying cylinder cover 201 along the axis of the guide rod 202 through the fixing component 203. The drying cylinder cover 201 gradually moves away from the drying cylinder 1, and at the same time, the scraper 2 is driven through the connecting rod 204. 05 slides on the inner wall of the drying cylinder 1 to scrape off the sand adhering to the inner wall of the drying cylinder 1, thereby improving the discharge efficiency. Through the set angle adjustment component 4, the drying cylinder 1 can be tilted, and the discharge port height is low. Under the action of weight, the sand can be discharged quickly. The drying cylinder cover 201 moves under the action of the first hydraulic cylinder 206, so that the operator does not need to touch the drying cylinder 1 directly, thus preventing burns. On the other hand, the movement of the drying cylinder cover 201 can drive the scraper 205 to move through the connecting rod 204, thereby scraping off the sand adhering to the inner wall of the drying cylinder 1 and improving the discharge efficiency.

[0034] Specifically, such as Figure 2 and Figure 4As shown, the drying assembly 3 includes an air supply pipe 303 that is connected to the drying cylinder 1. A heating box 301 is fixed at the end of the air supply pipe 303, and a fan 302 is installed inside the heating box 301. An electric heating wire 305 is installed below the fan 302. The drying assembly 3 also includes an exhaust pipe 304 that is connected to the drying cylinder 1. A stirring assembly 5 is also installed on the drying cylinder 1. A valve can be installed on the exhaust pipe 304, and a recovery assembly can be added. A one-way valve is installed on the air supply pipe 303 to allow the heating gas to be transported from the heating box 301 to the inside of the drying cylinder 1.

[0035] The stirring assembly 5 includes a servo motor 501 that is bolted to the side of the drying cylinder 1 away from the drying cylinder cover 201. The power output end of the servo motor 501 is fixed with a turntable 504, and a spiral blade 502 is fixed on the surface of the turntable 504. A dispersing rod 503 is arranged around the spiral blade 502.

[0036] By adopting the above technical solution, the fan 302 introduces external air into the heating box 301. After being heated by the heating wire 305, the heated gas is transported from the heating box 301 to the drying cylinder 1 through the air supply pipe 303, thereby drying the sand in the drying cylinder 1. At the same time, the sand can be heated by the rotation of the spiral blade 502. The servo motor 501 can drive the turntable 504 to rotate, and the turntable 504 can drive the spiral blade 502 and the dispersing rod 503 to rotate. The drying component 3 can send high-temperature gas into the drying cylinder 1, and work with the stirring component 5 to dry the sand at high temperature.

[0037] Working principle: In the initial state, the end of the drying cylinder 1 furthest from the drying cylinder cover 201 is lower, exhibiting a front-low-back-high configuration. Sand is fed into the drying cylinder 1 through the feed chute 6. After the feed chute 6 is closed, the fan 302 introduces external air into the heating chamber 301. After being heated by the heating wire 305, the heated gas is transported from the heating chamber 301 to the drying cylinder 1 through the air supply pipe 303, thereby drying the sand inside the drying cylinder 1. Simultaneously, the servo motor 501 is activated, driving the turntable 504 to rotate. The turntable 504 drives the spiral blades 502 and the dispersing rod 503 to rotate. During the drying process, the angle of the drying cylinder 1 can be adjusted. The pressure cylinder 401 and the second hydraulic cylinder 401 push the drying cylinder 1 to rotate upward, turning it into a front-high-rear-low state. The sand moves inside the drying cylinder 1 and is alternately arranged. After drying, the second hydraulic cylinder 401 adjusts the drying cylinder 1 to a front-high-rear-low state, and the sand moves towards the drying cylinder cover 201. The first hydraulic cylinder 206 pushes the drying cylinder cover 201 to move along the axis of the guide rod 202 through the fixing part 203. The drying cylinder cover 201 gradually moves away from the drying cylinder 1. At the same time, the connecting rod 204 drives the scraper 205 to slide on the inner wall of the drying cylinder 1 to scrape off the sand adhering to the inner wall of the drying cylinder 1, thereby improving the discharge efficiency.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
