Description

torrent spray device

technical field

The utility model relates to the technical field of automobile spraying pretreatment, in particular to a torrent spray washing device.

Background technique

In the pretreatment process of automobile painting, the first process is flood washing process, the purpose of which is mainly to wash iron filings and dirt in the car cavity. The current technology used is spraying and flushing with large flow of spray nozzles in the tank, and the spray pipelines in the tank are generally arranged horizontally, so that the body cannot be effectively cooled when the body is in the swing state of "leaning forward" and "leaning backward". For flushing, a large amount of spray tank liquid is sprayed to the parts other than the vehicle body, so that the spray efficiency is low, and the water volume of the spray pump is wasted greatly. Moreover, after the car is washed by spraying water, all the washed liquid flows into the tank, and through natural precipitation, the water in the upper layer is recycled, while the sediment accumulates at the bottom of the tank. With the accumulation of sediment, it is necessary to regularly clean the sediment in the tank. If the cleaning is not timely or the sediment is too much and is lifted up, the sediment will be sucked into the pump from the pump suction port, resulting in pipeline blockage, and even serious damage to the pump impeller. damage.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1-4, the torrent spray washing device of the present utility model includes a track 1 for carrying a car, a torrent tank for collecting flushing water, and a torrent pump for circulating spray water, and the car is fixed on On the swing rod, the swing rod is hung on the track and driven to travel, which is similar to the prior art, and will not be described here.

The track is continuously formed with a downhill section 11, a horizontal section 12 and an uphill section 13 above the torrent trough along the direction of travel, and a pair of water spray pipes 2 are respectively arranged at the front and rear ends of the torrent trough to pass through the windows of the car. The inner spraying water is used for flushing, and the pair of water spraying pipes are separated on both sides of the track and the openings are facing inward. Moreover, the two pairs of water spray pipes at both ends are alternately connected to the water outlet of the torrent pump. By adjusting the descending height of the track, the length of the horizontal section, and the pitch between the two cars, the alternate spraying of the torrent into the tank and out of the tank is realized.

Specifically, as shown in Figure 1, when the effective cleaning section corresponding to the window of car B in the forward leaning state is within the range of the right water spray pipe, the right water spray pipe emits water, and the left water spray pipe does not emit water. When the effective cleaning section of the car B in the forward leaning state leaves the range of the water spray pipe on the right side, as shown in Figure 2, the effective cleaning section of the car A in the backward state of the front just enters the range of the water spray pipe on the left side. The side spray pipe starts to discharge water, and the right spray pipe stops to discharge water. When the car in the leaning state leaves the left spray pipe, as shown in Figure 3, the new car C on the track just matches and enters the right side. After finishing the forward leaning state, car B enters the horizontal section for transitional waiting state. If it is a cycle, the whole process will be switched automatically according to the operating rhythm. Usually, the working condition of the total flow rate of the torrent is 200-250 cubic meters per hour. This intermittent The system only needs 100-125 cubic meters per hour, the pump flow rate of the torrent pump can be saved by 50%, and the electricity bill alone can save about 100,000 yuan per year.

At the same time, in order to improve the collection effect of rust and other sediments and avoid affecting the use of circulating water, the torrent tank includes diversion slopes 3 corresponding to the downhill section and the uphill section respectively, and a box-type settling tank arranged below the horizontal section 4. A water inlet hole 41 is formed on the left end of the top plate of the settling tank, and a collection chamber 42 protrudes downward from the lower part of the water inlet hole. The traveling direction of the track is the longitudinal direction, and the water inlet hole is arranged horizontally. The collection chamber extends laterally along the water inlet direction and has a conical longitudinal section. A controllable slag discharge valve is provided at the bottom of the collection chamber. The water inlet of the torrent pump and the right side of the settlement tank side connection. Further, in order to improve the sediment collection effect, at least two baffles are arranged in the settling tank, specifically, the baffles include a set of baffles arranged on the right side of the water inlet hole and fixedly connected with the lower surface of the top plate. An upper baffle 43 that keeps a distance from the bottom plate of the settling tank, and a lower baffle 44 that is arranged on the right side of the collection chamber and is fixedly connected with the bottom plate of the settling tank and whose upper end keeps a distance from the top plate.

Because the cross-section of the tank body is very large after entering the settling tank, the flow velocity is reduced after entering. At the same time, the upper baffle plate and the lower baffle plate cooperate to force the water flow direction to turn, and the water flow takes an "S" shape in the tank, which will settle The tank body of the tank is designed as a labyrinth structure, which forces the water to flow downward and upward. The solid particles in the water and other sediments are easily deposited in the tank by inertia and collected into the collection chamber, which effectively improves the filtering effect of the sediment, that is, increases the self-sedimentation The function of slag removal, at the same time, there is an automatic discharge valve at the bottom of the collection chamber, which can be automatically and regularly discharged by program control, reducing the load of other slag removal systems, and no longer needs to configure a complicated iron powder removal system. Further reduce torrent flushing costs.

Preferably, in order to effectively intercept impurities suspended in water such as fibers that are not easy to deposit, the water inlet of the torrent pump is arranged at the bottom of the side plate of the settling tank and a filter screen 45 is arranged in the settling tank.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these Improvement and retouching should also be regarded as the protection scope of the present utility model.
