[0001] The utility model relates to the technical field of tank-type semi-trailers, in particular to an external cleaning pipeline, a tank body and a semi-trailer. Background Art
[0002] A milk tanker is a special semi-trailer truck used to transport milk or other dairy products. Special milk tanks are installed on the semi-trailer to ensure the freshness of dairy products during transportation. The tank body of the milk tanker is made of welded stainless steel plates and has good sealing and corrosion resistance.
[0003] At present, in order to ensure the quality of milk, the existing milk tankers in China are strictly required to have cleaning pipes. There are two types of cleaning pipes. The first is to arrange the cleaning pipes inside the tank. This solution has the problem of cleaning dead corners, and many large dairy plants no longer allow it to be used; the second is to arrange the cleaning pipes outside the tank body (in the thermal insulation interlayer). Although the problem of cleaning dead corners is avoided in the thermal insulation interlayer, once a leak occurs in the cleaning pipe, it will be difficult to repair, and the thermal insulation material will also seep water.

[0031] like Figure 1-5 As shown, an external cleaning pipeline includes: a first pipeline 1, an outlet joint assembly 2, a second pipeline 3, a support seat 4, a third pipeline 5, and a nozzle assembly 6. The first pipeline 1 is connected to the rear of the tank body 7, the outlet joint assembly 2 is connected to the first pipeline 1, the second pipeline 3 extends along the length direction of the tank body 7, one end of the second pipeline 3 is connected to the first pipeline 1, and the other end is closed, the support seat 4 connects the second pipeline 3 to the top of the tank body 7, there are several third pipelines 5 and they are arranged in sequence along the length direction of the second pipeline 3, one end of the third pipeline 5 is connected to the second pipeline 3, and the other end extends into the tank body 7, and the nozzle assembly 6 is connected to the other end of the third pipeline 5.
[0032] Specifically, Figure 1-4 As shown, there are two first pipes 1 which are arranged side by side at the rear of the tank body 7. The first pipes 1 are buried in the thermal insulation interlayer at the rear of the tank body 7, so as to avoid exposure of the pipe structure at the rear of the tank body 7, improve the integrity and aesthetics of the tank body 7 structure, and reduce the risk of damage to the pipe structure.
[0033] Specifically, Figure 2 , 5As shown, there are two rows of second pipes 3 which are respectively connected to both sides of the walkway at the top of the tank body 7. Each pipe is connected to the walkway through a support seat 4. The two rows of second pipes 3 form a fence structure at the top of the tank body 7, thereby improving the safety of operators walking on the top of the tank body 7.
[0034] Specifically, Figure 4 As shown, the outlet joint assembly 2 includes: a tee 201, a union 202, and a sealing cover 203. Each second pipeline 3 is connected to a first pipeline 1. The tee 201 is connected to the two first pipelines 1 through a flat joint. The union 202 is connected to the tee 201. The sealing cover 203 is installed on the union 202. The structural design of the outlet joint assembly 2 forms an assembled combined joint, which is convenient for adjusting the filling angle during cleaning, reducing the stress degree of the cleaning pipeline, and increasing the service life.
[0035] Specifically, Figure 4 As shown, the lower end of the first pipeline 1 is connected with a straight pipe and a bent pipe in sequence, and the ends of the first pipeline 1, the straight pipe and the bent pipe are all provided with shoulders, which are disc-shaped structures, and adjacent shoulders are formed into a detachable connection structure through a clamp, and a sealing ring is arranged between adjacent shoulders for sealing, and the straight pipe is provided with an assembled butterfly valve, and the pipeline is controlled to be on and off by the assembled butterfly valve, and a flat joint is welded at the end of the tee pipe 201, and the flat joint includes a pipe mouth and a shoulder, and the pipe mouth is welded to the tee pipe 201, and the shoulder of the flat joint is assembledly connected to the shoulder of the bent pipe through a clamp, and the tee pipe 201 is detachably connected to the first pipeline 1 through the flat joint, so as to facilitate the adjustment of the filling angle of the union joint 202 during cleaning.

Each section in the tank body 7 refers to an area separated by wave-breaking plates. The third pipes 5 are evenly distributed in the second pipes 3, so that different third pipes 5 have similar pressures.
[0038] Specifically, Figure 3 , 5As shown, a connecting pipe is extended from the second pipe 3 corresponding to the third pipe 5. The connecting pipe is arranged in a direction perpendicular to the second pipe 3. A shoulder is arranged at the end of the connecting pipe. The shoulder at the end of the third pipe 5 is detachably connected to the shoulder of the connecting pipe through a clamp. The detachable connection structure facilitates the inspection and maintenance of the pipe.
[0039] Specifically, Figure 5 As shown, the nozzle assembly 6 includes: a one-way valve 601, a cleaning nozzle 602, the one-way valve 601 is connected to the third pipe 5, and the cleaning nozzle 602 is connected to the one-way valve 601, wherein the third pipe 5 is a 1.5-inch steel pipe, and the third pipe 5 extends into the interior of the tank 7 for a length of about 550 mm. The third pipe 5 is welded with a threaded joint, and the threaded joint is sequentially installed with a one-way valve 601, an external thread straight-through, and a cleaning nozzle 602, and the one-way valve 601 is used to improve the working stability of the cleaning nozzle 602.
[0040] Since most of the external cleaning pipeline is arranged outside the tank body 7, it is convenient for maintenance personnel to quickly find the leakage point when the pipeline leaks, and each part of the pipeline is connected by a clamp assembly, which is convenient for disassembly and maintenance of the pipeline, solving the problem that the existing milk tanker cleaning pipeline is inconvenient to maintain.
