Description

Technical Field

[0001] This utility model relates to the field of tank truck technology, specifically to an internal anti-surge baffle structure for tank trucks. Background Technology

[0002] Liquid tanker trucks typically have baffles installed inside the tank. However, with market demand, the strength of the baffles is insufficient under the lightweight design of the tank body. It is necessary to add reinforcing ribs to the baffles and triangular plates welded to the tank body for reinforcement. This structure increases the weight, and the tank body production requires multiple processes to complete this structure. At the same time, the arched excess material generated around the baffles during production is difficult to reuse and can only be discarded as waste. The weight, cost, and production complexity are difficult to achieve as expected. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects and shortcomings of the existing technology and provide a tank truck internal anti-surge baffle structure that is simple in structure, low in cost, high in strength, and easy to produce.

[0004] To achieve the above objectives, the technical solution of this utility model is: a baffle plate structure inside a tank truck, comprising a plate body, wherein a manhole is provided at the center of the plate body, and an upper flow hole and a lower flow hole are respectively provided on the plate body on the upper and lower sides of the manhole, and anti-rollover ventilation holes are respectively provided on the plate body on the left and right sides of the manhole, characterized in that: a back ring is provided on the outer edge of the back of the plate body.

[0005] The lower flow hole is designed as an arched doorway, and sealing plates are provided on both sides of the bottom of the lower flow hole. The sealing plates are connected to the back ring.

[0006] The plate body is generally in the shape of a hydraulic arc, and the back rings are welded back to back to the arc-shaped side of the plate body.

[0007] The back ring arc shape is consistent with the spiral edge arc shape of the plate, and the back ring thickness is consistent with the plate thickness.

[0008] The manhole, upper flow hole, and lower flow hole are all equipped with flanges.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] 1. This utility model employs a back-to-back welding method to the outer edge of the arched side of the plate, which increases the strength of the baffle and prevents residue from entering the included angle. By defining the shape and thickness of the back ring, a better fit between the back ring and the tank body and the baffle is achieved. For special wine or milk tanks, this baffle with a back ring structure also facilitates passivation treatment inside the tank.

[0011] 2. This utility model has sealing plates on both sides of the bottom of the lower flow hole, and the sealing plates are welded together with the back ring. This can seal the included angle gap to prevent residue from entering the gap, and also reduce the stress concentration caused by the sharp corner of the lower flow hole.

[0012] 3. In this utility model, the manhole, upper flow hole and lower flow hole are all provided with flanges, which can increase the strength of the opening and reduce the flow resistance. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] See Figures 1-3 A baffle structure for the interior of a tanker truck includes a plate 1 that is generally in the shape of a hydraulic arc. A manhole 2 is provided at the center of the plate 1. An upper flow hole 3 and a lower flow hole 4 are respectively provided on the upper and lower sides of the plate 1 above the manhole 2. All three flow holes, including the manhole 2, the upper flow hole 3, and the lower flow hole 4, are provided with flanges. Anti-tipping vent holes 5 are respectively provided on the left and right sides of the plate 1. A back ring 6 is welded back to back along the outer edge of the arc side of the plate 1. The arc shape of the back ring 6 is consistent with the arc shape of the spiral edge of the plate 1, and the thickness of the back ring 6 is consistent with the thickness of the plate 1, which can better fit the tank and the plate 1.

[0019] The lower flow hole 4 is designed as an arched doorway. Sealing plates 7 are provided on both sides of the bottom of the lower flow hole 4. The sealing plates 7 have folded edges and are welded together with the back ring 6 and the plate body 1.

[0020] The entire board 1 needs to be cut 3 times. The first cut is the outer contour of the back ring 6. After the edge is shaped, the second and third cuts are made. The second cut is the inner contour of the back ring 6, and the third cut is the outer contour of the board 1. Finally, the edge is shaped. The production of the back ring 6 does not require additional equipment and can make the most of the board material.
