Description

Technical Field

[0001] This utility model relates to the field of tank truck unloading technology, specifically to an unloading device for tank trucks. Background Technology

[0002] Regarding the storage structure of tank truck storage tanks, most traditional tanks have a conventional storage space design with a simple internal structure and lack a scientific and reasonable layout. This leads to low feeding and discharging efficiency during material entry and exit. The common straight-cylinder storage space results in poor material flow within the tank, easily causing liquid residue accumulation. This not only wastes material but may also affect the quality of the next batch of stored material due to spoilage of the residue. Cleaning up residue also increases additional manpower and time costs. In terms of unloading control, traditional unloading devices lack flexibility in material entry and exit control, making it difficult to accurately control the unloading process. Regarding unloading power, many traditional unloading devices rely on the material's own gravity for unloading, lacking effective power auxiliary equipment. This results in slow unloading speed and long unloading time, seriously affecting overall work efficiency. Utility Model Content

Example two

[0023] As shown in Figure 1 , Figure 4 and Figure 5 , feeding area assembly 3 includes upper half shell 301 and lower slope shell 302, the top of lower slope shell 302 is inclined to the inside of storage assembly 2 in slope shape, the top end of upper half shell 301 and lower slope shell 302 is fixedly connected, upper half shell 301 and lower slope shell 302 are combined in semicircular shape, when the material enters upper half shell 301, it slides into storage assembly 2 along the slope of lower slope shell 302, the cut-off valve 8 at the feeding pipe 6 can control the inflow and stop of the material;

[0024] The discharge area assembly 4 comprises an upper inclined slope shell 401 and a lower half shell 402, and the filter plate 5 is arranged at the inner end of the upper inclined slope shell 401 and the lower half shell 402. The combination of the upper inclined slope shell 401 and the lower half shell 402 is a semicircle.

[0025] Working principle: as shown in Figures 1-5 The upper inclined slope channel 201 and the lower inclined slope channel 202 of the storage assembly 2 are mutually butted to form a unique storage space. When the material enters through the feeding area assembly 3, the wider part of the upper inclined slope channel 201 receives the material from the feeding area assembly 3. Since the internal space of the upper inclined slope channel 201 is opposite at both ends, the material can flow and store along the inclined slope channel. The lower inclined slope channel 202 also plays a role in auxiliary storage and guiding the flow of the material. The wider part can also store part of the material, and is butted to the inner end of the discharge area assembly 4 and the feeding area assembly 3 to maintain the reasonable distribution of the material in the storage assembly 2.

[0026] Material input: the material enters the feeding area assembly 3 through the feeding pipe 6. When the material enters the upper half shell 301, it slides into the storage assembly 2 along the slope of the lower inclined slope shell 302. The shut-off valve 8 at the feeding pipe 6 can control the inflow and stop of the material.

[0027] Material output: when discharging, the shut-off valve 8 at the discharge pipe 7 is opened, and the unloading pump 9 is started to generate suction. The material in the storage assembly 2 flows to the discharge area assembly 4 through the narrower part of the upper inclined slope channel 201 under the action of the unloading pump 9. The upper inclined slope shell 401 and the lower half shell 402 of the discharge area assembly 4 jointly receive the material. After the material is filtered by the filter plate 5, the material is discharged from the discharge pipe 7. The shut-off valve 8 can be closed at any time to cut off the discharge port. The liquid level meter 10 monitors the material liquid level in the tank shell 1 in real time, and feeds back information to the controller 12, so that the operator can master the material condition in the storage tank.
