Description

Technical Field

[0001] The utility model relates to the technical field of subway mortar, and more specifically, to a mortar storage and mixing tank. Background Art

[0002] The subway is a form of rail transportation, referring to an urban rail transit system that mainly operates underground, which is the abbreviation of "subway" or "metro". In order to adapt to the construction environment and consider the construction and operation costs, many such systems will be converted into ground or elevated sections outside the city center.

[0003] A large amount of mortar is required in the construction process of the subway. The mortar can be used directly after preparation. However, when there is too much mortar, it cannot be used in time and needs to be stored in a mortar storage tank. However, the existing mortar storage tank has a relatively simple function and only has a stirring function to prevent the mortar from coagulating. When the mortar is exported, a lot of mortar is easily adhered to the inner wall of the tank body, which not only causes a waste of resources, but also requires frequent processing of the mortar adhered to the inner wall of the tank body, which is time-consuming and labor-intensive. Utility Model Content

[0008] In a preferred embodiment, the upper and lower ends of the scraper ring are both set to be cones, and the outer wall of the scraper ring is set to fit the inner wall of the tank body. The scraper ring with a conical structure can clean the inner wall of the tank body when lifting and lowering, especially the conical structure at the upper end can make the scraped mortar slide off.

[0009] In a preferred embodiment, a discharge port is provided at the bottom end of the tank body, and a control valve is provided at the discharge port. The setting of the discharge port facilitates the discharge of mortar.

[0010] In a preferred embodiment, the bottom end of the stirring rod is rotatably connected to the bottom inner wall of the tank body via a planar thrust ball bearing, and an O-ring is arranged inside the planar thrust ball bearing, which effectively prevents the problem of fixing the lower part of the stirring rod and water sealing in the lower bearing.

[0011] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0012] The utility model is provided with a transmission mechanism and a scraper ring. The driving motor can not only drive the stirring rod to stir the mortar to prevent the mortar from coagulating, but also can utilize the reverse rotation of the driving motor to drive the lifting of the scraper ring through the transmission mechanism after the mortar is discharged, so that the scraper ring can scrape off the mortar adhered to the inner wall of the tank body, thereby realizing the cleaning of the inner wall of the tank body and reducing the probability of manual cleaning.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] according to Figure 1-Figure 3 A mortar storage and mixing tank shown in the figure includes a tank body 1, a driving motor 2 is fixedly arranged on the upper end of the tank body 1, the output shaft of the driving motor 2 is fixedly connected to a driving sprocket 3, the driving sprocket 3 is connected to a first driven sprocket 5 and a second driven sprocket 6 through a chain 4, the first driven sprocket 5 is connected to the input end of a reducer 7, the output end of the reducer 7 is fixedly connected to a stirring rod 8 arranged inside the tank body 1, a scraper ring 9 is arranged inside the tank body 1, and the scraper ring 9 is connected to the second driven sprocket 6 through a transmission mechanism.

[0019] In a preferred embodiment, the transmission mechanism includes a first rotating shaft 10 arranged on the inner side of the second driven sprocket 6, and a plurality of engaging teeth 11 are evenly spaced on the outer wall of the first rotating shaft 10. Two limit rods 12 are hingedly provided on the inner wall of the second driven sprocket 6. A driving pulley 13 is fixedly provided at one end of the rotating shaft 10, and the driving pulley 13 is connected to a driven pulley 15 through a belt 14. A second rotating shaft 16 is fixedly connected to the middle position of the driven pulley 15, and two winding wheels 17 are fixedly provided on the second rotating shaft 16. The winding wheel 17 is connected to the scraper ring 9 through a pull rope 18.

[0020] In a preferred embodiment, a card slot 19 is provided on the engaging teeth 11, and guide wheels 20 are provided on both sides of the upper end of the tank body 1. The pull rope 18 is arranged through the guide wheel 20, and the limiting rod 12 can abut against the card slot 19 to rotate the first rotating shaft 10. The setting of the guide wheel 20 enables the pull rope 18 to connect the scraper ring 9 with the winding wheel 17.

[0021] In a preferred embodiment, the upper and lower ends of the scraper ring 9 are both set to be conical, and the outer wall of the scraper ring 9 is set to fit the inner wall of the tank body 1. The conical structure at the upper end can make the scraped mortar slide along the conical structure.

[0022] In a preferred embodiment, a discharge port 21 is provided at the bottom end of the tank body 1, and a control valve is provided at the discharge port 21. A feed port is provided at the upper end of the tank body 1, and the feed port and the discharge port 21 facilitate the entry and exit of mortar.

[0023] In a preferred embodiment, the bottom end of the stirring rod 8 is rotatably connected to the bottom inner wall of the tank body 1 via a planar thrust ball bearing, and an O-ring is arranged inside the planar thrust ball bearing. The planar thrust ball bearing effectively prevents the problem of fixing the lower part of the stirring rod and the problem of water sealing in the lower bearing.

[0024] The specific implementation method is as follows: the mortar is introduced into the tank body 1 through the feed port, and the driving motor 2 is turned on to drive the driving sprocket 3 to rotate.

The stirring rod 8 can stir the mortar to prevent the mortar from coagulating. When it is needed, the mortar can be discharged. When the inner wall of the tank body 1 needs to be cleaned, the driving motor 2 is rotated in the opposite direction, and the driving motor 2 drives the second driven sprocket 6 to rotate in the opposite direction, so that the limiting rod 12 on the inner side of the second driven sprocket 6 abuts against the groove on the side wall of the engaging tooth 11. In 19, the second driven sprocket 6 drives the first rotating shaft 10 to rotate, the first rotating shaft 10 drives the driving pulley 13 to rotate, and the driving pulley 13 drives the driven pulley 15 to rotate through the belt 14, so that the second rotating shaft 16 drives the two winding wheels 17 to rotate, and the winding wheel 17 winds up the pull rope 18, so that the pull rope 18 pulls the scraper ring 9 to move upward, and the scraper ring 9 can clean the inner wall of the tank body 1. After the scraper ring rises to a certain extent, the drive motor 2 is turned off, and the scraper ring 9 moves downward under the action of gravity, and then the drive motor 2 is turned on again to make the scraper ring 9 rise, which has a better cleaning effect on the tank body 1.
