Description

Technical Field

[0001] This utility model relates to a moisture-proof tank for dry-mixed mortar. Background Technology

[0002] Dry-mixed mortar is one of the emerging dry-mixed materials in the building materials industry. It is a mixture made by mixing cement as the main binder with dried and screened fine aggregates, mineral admixtures, reinforcing materials and additives in a certain proportion. It can be directly added to the mixing equipment and mixed with water to make mortar. The produced dry-mixed mortar is transported to the construction site in bagged or bulk form and stored in the warehouse. When needed, the dry-mixed mortar can be pulled out, mixed with water and used directly.

[0003] With the advancement of storage technology and devices, the storage for dry-mixed mortar has shifted from warehouses to moisture-proof tanks. However, existing moisture-proof tanks for dry-mixed mortar still have some shortcomings, such as: First, while traditional sealed tanks can isolate external rainwater, they cannot solve the problem of condensation inside the tank itself. Diurnal or seasonal temperature differences can cause temperature variations on the tank wall and material surface. When humid, hot air encounters the cold tank wall, it condenses into water droplets, which is the main reason for the dry-mixed mortar becoming damp and hardened. Second, many tanks use simple covers or a few bolts to tighten the inlet and outlet, resulting in poor sealing reliability. In humid environments, moisture can still seep into the tank through tiny gaps. Third, if the screw conveyor is installed horizontally or at an improper angle, material can easily remain at the bottom of the conveyor or at the tank outlet, causing waste and potentially clogging the outlet over time. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a moisture-proof tank for dry-mixed mortar.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A dry-mixed mortar moisture-proof tank includes a storage tank, a spiral feeding mechanism installed above the storage tank, a spiral discharging mechanism installed below the storage tank with the same structure as the spiral feeding mechanism, a heat dissipation pipe installed inside the storage tank with both ends passing through the outside of the storage tank, and an air supply mechanism located outside the storage tank and connected to the heat dissipation pipe. The heat dissipation pipe is C-shaped, and an elliptical cavity is provided at the central part of the heat dissipation pipe inside the storage tank. A mesh cover is installed at the upper end of the heat dissipation pipe, and the lower end of the heat dissipation pipe is connected to the air supply mechanism.

[0006] Preferably, the air supply mechanism includes an air supply fan and an air supply pipe with one end connected to the air supply fan and the other end connected to the lower end of the heat dissipation pipe.

[0007] Preferably, the storage tank includes a tank body, an inlet located on the top of the tank body and installed in conjunction with a screw feeding mechanism, an inlet sealing cover hinged to the inlet, an inlet side frame welded to one side of the inlet for fixing and supporting the screw feeding mechanism, an outlet located on the bottom of the tank body with the same structure as the inlet, an outlet sealing cover hinged to the outlet and with the same structure as the inlet sealing cover, and an outlet side frame welded to one side of the outlet for fixing the screw discharge mechanism.

[0008] Furthermore, a bushing is welded to the side of the feed inlet facing the feed side frame; Furthermore, the upper side of the feed inlet is integrally formed with several sealing cap holders.

[0009] Furthermore, the side of the feed inlet sealing cover is hinged with several locking studs with locking nuts; The inner edge of the inlet sealing cover is provided with an annular insert groove, and a sealing ring is embedded in the annular insert groove, with a part of the sealing ring protruding out of the annular insert groove.

[0010] Furthermore, the feed side frame and the discharge side frame are inclined welded assembly.

[0011] Preferably, the screw feeding mechanism includes a drive motor, a coupling fixedly mounted on the output end of the drive motor, a screw rod located inside the feed inlet and connected to the coupling, a shaft seal sleeve fitted on the screw rod and facing the coupling, and a fixing flange fitted on the screw rod and fixed to the feed inlet by bolts.

[0012] The beneficial effects of this utility model are as follows: 1. Through the built-in heat dissipation pipes and air supply mechanism, the dry-mixed mortar inside the tank is actively cooled down, effectively balancing the temperature inside the tank and significantly reducing the temperature difference between the tank wall and the material, thereby preventing and eliminating the "condensation" phenomenon from the root. 2. The double sealing structure, consisting of a locking stud with a locking nut and a protruding sealing ring, provides a strong and uniform clamping force, ensuring that the sealing ring can effectively deform and fill all gaps, achieving a near-airtight sealing effect and completely blocking the intrusion path of external humid air. 3. The feed side frame and discharge side frame are designed with inclined welding to ensure that the screw feed mechanism and discharge mechanism are at the optimal working angle. By utilizing the gravity characteristics of the material, the feeding and discharging are smoother and more thorough, reducing dead corners and residues and improving production efficiency. Attached Figure Description

[0013] Figure 1 This is a structural diagram of a dry-mixed mortar moisture-proof tank according to the present invention; Figure 2 for Figure 1Exploded view; Figure 3 for Figure 1 Cross-sectional view. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0015] Example like Figure 1-3 As shown, a dry-mixed mortar moisture-proof tank includes a storage tank 1, a spiral feeding mechanism 2 installed above the storage tank 1, a spiral discharging mechanism 3 installed below the storage tank 1 and having the same structure as the spiral feeding mechanism 2, a heat dissipation pipe 4 installed inside the storage tank 1 and having both ends passing through the outside of the storage tank 1, and an air supply mechanism 5 located outside the storage tank 1 and connected to the heat dissipation pipe 4.

[0016] The storage tank 1 includes a tank body 11, an inlet 12 located above the tank body 11 and installed in conjunction with the screw feeding mechanism 2, an inlet sealing cover 13 hinged to the inlet 12, an inlet side frame 14 welded to one side of the inlet 12 for fixing and supporting the screw feeding mechanism 2, an outlet 15 located below the tank body 11 with the same structure as the inlet 12, an outlet sealing cover 16 hinged to the outlet 15 and with the same structure as the inlet sealing cover 13, and an outlet side frame 17 welded to one side of the outlet 15 for fixing the screw discharge mechanism 3.

[0017] A bushing 121 is welded to the side of the feed inlet 12 facing the feed side frame 14; Several sealing cap holders 122 are integrally formed on the upper side of the feed inlet 12.

[0018] The side of the inlet sealing cover 13 is hinged with several locking studs 131 with locking nuts. Specifically, when the inlet sealing cover 13 contacts the inlet 12, the locking studs 131 are locked in the sealing cover seat 122. Then, by tightening the locking nuts, the inlet sealing cover 13 is pressed against the inlet 12 to seal it. An annular groove 132 is formed on the inner edge of the inlet sealing cap 13, and a sealing ring 133 is embedded in the annular groove 132. A portion of the sealing ring 133 protrudes from the annular groove 132. Specifically, when the inlet sealing cap 13 is pressed against the inlet 12 to close it, the sealing ring 133 can fill the gap between the inlet sealing cap 13 and the inlet 12, thereby preventing the tank 11 from getting wet. The structure of the locking stud 131 and the locking nut can generate a large downward pressure to ensure that the cap is tightly closed.

[0019] The protruding annular groove in the sealing ring 133 ensures that it can deform fully during compression, perfectly filling all micro gaps and effectively preventing the intrusion of external humid air. In addition, the inlet and outlet adopt the same structure and sealing scheme, which simplifies the manufacturing process and ensures consistent sealing reliability of all openings in the whole tank.

[0020] The feed side frame 14 and the discharge side frame 17 are welded at an angle, which facilitates the inclined installation of the screw feed mechanism 2 and the screw discharge mechanism 3, and promotes smooth feeding or discharging. This makes the installation angle of the screw feed mechanism 2 and the screw discharge mechanism 3 more in line with the material flow characteristics, reduces material residue and conveying resistance, and ensures smooth and efficient feeding and discharging.

[0021] The screw feeding mechanism 2 includes a drive motor 21, a coupling 22 fixedly mounted on the output end of the drive motor 21, a screw rod 23 located inside the feed inlet 12 and connected to the coupling 22, a shaft seal sleeve 24 fitted onto the screw rod 23 and facing the coupling 22, and a fixing flange 25 fitted onto the screw rod 23 and fixed to the feed inlet 12 by bolts. Furthermore, the screw discharge mechanism 3 has the same structure as the screw feeding mechanism 2, using the same standard parts or modules, reducing the manufacturing and maintenance costs of the equipment and the complexity of spare parts inventory.

[0022] It should be further noted that the shaft seal sleeve 24 uses a mechanical seal of model WB2-40 and is compatible with the diameter of the spiral rod 23.

[0023] The heat dissipation pipe 4 is C-shaped and has an elliptical cavity pipe 41 located in the center of the inside of the storage tank 1. A mesh cover 42 is installed at the upper end of the heat dissipation pipe 4, and the lower end of the heat dissipation pipe 4 is connected to the air supply mechanism 5. The mesh cover 42 at the upper end of the heat dissipation pipe 4 can effectively prevent debris or large pieces of material from falling into the pipe and causing blockage, thus ensuring the long-term stable operation of the air supply system.

[0024] Specifically, the elliptical cavity tube 41 can increase the contact area between the heat dissipation tube 4 and the dry mortar inside the tank 11, thereby using the air passing through the heat dissipation tube 4 to remove the heat generated by the dry mortar due to stacking, and can avoid the dry mortar from becoming damp due to the temperature difference between the inside and outside of the tank.

[0025] The air supply mechanism 5 includes an air supply fan 51 and an air supply pipe 52, one end of which is connected to the air supply fan 51 and the other end of which is connected to the lower end of the heat dissipation pipe 4.

[0026] It should be further explained that, through the built-in heat dissipation pipe 4 and air supply mechanism 5, the dry-mixed mortar in the center of the tank 1 is actively cooled down, effectively balancing the temperature inside the tank and significantly reducing the temperature difference between the tank wall and the material, thereby preventing and eliminating the "condensation" phenomenon from the root.

[0027] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
