Fig. 2 is a partial enlarged view of the region S in fig. 1.

Detailed Description

The utility model provides a tank truck unloading anti-leakage system, which is used for making the purposes, the technical scheme and the effects of the utility model clearer and more definite, and is further described in detail below. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1, the present utility model provides a tank truck unloading anti-leakage system. The drawings are only for the purpose of illustrating the structural principles and are not to scale with respect to actual products. The pit, and submerged pump, is below ground and cannot be directly observed from the perspective of fig. 1. The pipes and valves located in the leak-proof pit are also not directly visible from the perspective of fig. 1. The term "plurality" as used herein means at least "1", and is not particularly limited since the number of certain structures is not the point of the utility model.

The tank truck unloading anti-leakage system comprises an unloading pump 1, wherein a feeding valve 2 is arranged on an inlet pipeline of the unloading pump, and the inlet end of the feeding valve is connected with a hose 3; the outlet pipeline 11 of the discharge pump is connected with a plurality of branch pipes 111, and each branch pipe is provided with a discharge valve 1110; a leakage prevention pit 4 is arranged below the hose, and a pit 5 is also arranged in the leakage prevention pit; a submerged pump 6 is arranged in the pit, and an outlet pipe 61 of the submerged pump is connected to an outlet pipe 11 of the discharge pump; a canopy 8 is arranged above the pit. Only the main body of the awning is shown in the drawings, in practical application, the awning can be provided with a plurality of vertical support rods (not shown in the drawings), or the awning is connected with the outer wall of a nearer factory building so as to realize the support of the awning, and the awning is not limited herein. In practical application, each branch pipe is respectively connected to the corresponding storage tank. The storage tanks themselves are not within the scope of the present utility model, and therefore the structure and number of the storage tanks are not particularly limited.

As can be seen from the figures, the arrangement of the canopy requires that the leakage-proof pit be completely covered and that rain drops to the leakage-proof pit be avoided.

Further, the bottom and side walls of the leak-proof pit, and the bottom and side walls of the pit are covered with a waterproof coating (not shown in the drawings). By arranging the waterproof coating, materials entering the anti-leakage pit and in the pit are prevented from further penetrating into the ground.

Preferably, the waterproof coating is an epoxy coating. The epoxy resin coating has strong adhesiveness and excellent chemical resistance, and can effectively prevent materials from passing through the coating.

Preferably, the depth of the leak-proof pit is 0.2 to 0.3 meter; the depth of the pit is 1.0-1.2 meters. Preferably, the area of the anti-leakage pit is 4m×4m, and the area of the pit is 0.4m×0.4m. The area of the anti-leakage pit is relatively large so as to provide a large leakage receiving area, and the depth of the anti-leakage pit is shallower so as to reduce potential safety hazards, so that safety accidents can not occur even if someone carelessly slips off the anti-leakage pit. The pit area is relatively small, and the depth is relatively deep, so that materials are collected in the pit for centralized treatment, and pumped out through a submerged pump.

Preferably, the slope angle of each side wall of the anti-leakage pit is not more than 60 degrees, and the arrangement makes each side wall of the anti-leakage pit slope slowly, so that people are prevented from carelessly falling into the anti-leakage pit vertically.

Further, guardrails (not shown in the figure) are arranged around the anti-leakage pit, and idle people and the like are prevented from entering the guardrails, so that accidents are avoided.

In practical application, the position that causes the material to leak because of unloading mainly lies in this section of region between the discharge valve 90 to the discharge pump import valve of tank car 9, prevents leaking the area in hole and can satisfy this section of region, and the careless emergence leaks when operating, and the material can enter into in the preventing leakage hole, further flows into the pit again, pumps out through the submerged pump and sends into the outlet pipe of discharge pump, has avoided the material to cause environmental pollution promptly, can also collect the material that leaks promptly and send into corresponding storage tank.

It will be understood that equivalents and modifications will occur to those skilled in the art based on the present utility model and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present utility model.
