Field of the Invention The present invention relates to a hose for a tank truck used for transporting bulk material such as flour or cement in bulk. [0002] In the transport of flour and cement, bulk transport by tank trucks as well as transport by bags are often used. The unloading from the tank is sent to the user's factory silo using this flexible hose. The flexible hose is loaded on a truck, and is used by a driver when unloading. [0003] In this transportation method, gravity is dropped from a silo or a tank of a factory or by a pneumatic transportation of a pressure type to push the tank into a tank of a tank car, and a gate is sealed to prevent foreign substances from being mixed. Generally, in a flour mill, a sieve is placed immediately before a product shipping port to prevent foreign substances from being mixed, thereby preventing foreign substances from entering. In addition, a bread factory, which is a user of flour, often has a sieve at a receiving port for flour as a raw material. Despite the strict check, foreign matter may come out. [0004] However, it is actually the case that small users do not provide a sieve at the flour receiving port, and a countermeasure in such a case is required.
On the other hand, in such a case, it is conceivable to attach a sieve to the tank truck and carry out receiving and paying out to the tank truck, but it is very difficult in view of a space for mounting the sieve. Furthermore, when unloading, it is necessary to do it in the shortest possible time,
Inefficient sieves are difficult to use. [0005] The flour coming out of the unloading port in a flour mill passes through a fairly fine screen, so that no large foreign matter enters. Never before.
Some have a screen in the middle of the air transport pipe,
Cleaning and maintenance of the screen was troublesome and cumbersome. The present invention has been made in view of the above points, and when discharging flour or the like from a tank truck, a relatively large foreign substance is formed using a simple screen at a joint portion connected to the tank truck. It is an object of the present invention to provide a tank truck hose to be removed. [0007] In order to solve the above-mentioned problems, the present invention relates to a hose having a joint portion used in connection with a tank of a tank truck when unloading flour or the like from a tank truck. The cross section of the inflow port of the joint portion
And a wire mesh in which wires are arranged in a grid at intervals of 5 to 20 mm . [0008] during and unloading of wheat flour from [action] tanker, it is possible to reliably remove the more foreign substances wire mesh provided on the inlet side of the hose connecting to the tank car. In addition, foreign matter that has caught on the wire mesh can be easily removed when the hose is removed. The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a joint portion of a tank truck hose of the present invention to a tank truck, and FIG. 2 is a sectional view of a joint portion of the tank truck hose of the present invention to a tank truck. As a method of discharging the flour put in the tank of the tank car to the silo on the receiving side, there is a pneumatic discharge type discharging method. In the pneumatic feed type, compressed air driven by a compressor or a blower is fed into a tank, pressurized to a predetermined pressure, and then mixed with compressed air and flour outside the vehicle for about 10 to 30 m / s.
Pumping and discharging at an air speed of ec. In order to discharge the flour, a flexible hose 1 is connected between the tank of the tank car and the silo on the receiving side. The joint of the hose 1 is connected to the tank of the tank truck. This coupling hose uses a coupling having a structure different from that of the connection joint with the pipe on the silo side. Particularly, the high pressure is applied to the joint on the tank truck side. As shown in FIGS. 1 and 2, the joint portion includes a flared portion 2 at an inlet of a hose 1 and a coupling 6 for connecting the flared portion 2 to a tank discharge port 8 of a tank car via a rubber packing 7. It is composed of
The coupling 6 is, for example, a ring divided into two as shown in FIG. 2, and has a mountain-shaped cross section. Inside the mountain, the expanded portion of the flared portion 2 of the hose 1 and the tank outlet 8 are formed.
Are inserted in abutment with each other, and the split ring is tightened to connect the two. In addition, the rubber hose part 4 having a diameter of about 100 to 120 mm
Is connected. The other end of the rubber hose portion 4 is provided with a coupling for connecting to a pipe attached to the flour receiving silo, and thereby connected to the receiving pipe. A metal filter net, that is, a wire net 5 is attached to the hose 1 on the trumpet-side flour inflow side, that is, the tank truck side. The wire mesh 5 is a wire mesh in which wires are arranged in a grid at intervals of about 5 to 20 mm. 1 and 2, the wire mesh 5
Is attached to the large diameter part at the entrance of the trumpet-shaped part 2,
The wire mesh 5 is preferably mounted on the side closer to the small diameter portion of the flared portion 2 as shown by the dotted line in FIG. In this way, the air flow during the unloading transportation goes smoothly, and other effects remain unchanged. The flour flows together with the compressed air from the tank of the tank truck into the hose 1 in the direction A and is discharged in the direction A into the silo. Tank truck loading is usually 10-15
The loading and unloading is completed in 30 to 50 minutes with tons. When loading / unloading is completed, remove the hose from both the tank truck and the receiving pipe,
This hose is housed in a truck. Since the wire mesh 5 is attached to the hose inlet on the tank truck side, foreign matters can be easily removed when the wire mesh 5 is removed. In the above embodiment, the present invention has been described with respect to the discharge of flour from a tank truck, but the present invention can also be applied to other powdered food products. As described above, according to the present invention, a wire mesh is attached to the flour inlet of the joint portion of the hose that is connected to and disconnected from the tank truck each time it is used.
By removing the hose, a wire mesh appears, and relatively large foreign substances in the flour accumulated in the wire mesh can be easily removed. In addition, the installation of the wire net having such dimensions does not particularly increase the unloading time from the tank truck.
