This feeding method has the advantages of being simple, fast and convenient, but the following disadvantages have been found during long-term use: the guide pipe is long, and its inner wall will accumulate resin residue during use. Excessive accumulation of resin residue will affect the normal feeding operation of the guide pipe and cause blockage problems. The guide pipe is often laid on an elevated structure, which is inconvenient for staff to clean. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0017] Embodiment 1:

[0018] Refer to the attached Figure 1As shown, a quantitative feeding device for refractory resin includes a metering pump 1, which is connected to a feed pipe 11 and a discharge pipe 12, the feed pipe 11 is connected to the discharge end of the feeding tank, the discharge pipe 12 is connected to a guide pipe 2, and the end of the guide pipe 2 is connected to the feeding end of the mixing tank; a first electric valve 21 is installed at the feed end of the guide pipe 2, and a second electric valve 22 is installed at the discharge end of the guide pipe 2, the first electric valve 21 and the second electric valve 22 are opened during discharge and closed during liquid discharge; a liquid outlet pipe 3 is connected to the guide pipe 2, the liquid outlet pipe 3 is close to the second electric valve 22 and a third electric valve 31 is installed on the discharge pipe 42, the third electric valve 31 is closed during discharge and opened during liquid discharge; a hot water component is also connected to the guide pipe 2, and a fourth electric valve 43 is installed on the hot water component, the fourth electric valve 43 is closed during discharge and opened during liquid discharge.

[0019] Specifically, the hot water component includes a liquid pump 4, a liquid inlet pipe 41 and a liquid discharge pipe 42; the liquid pump 4 is connected to the liquid inlet pipe 41 and the liquid discharge pipe 42, the liquid inlet pipe 41 is connected to an external hot water source, the liquid discharge pipe 42 is connected to the material guide pipe 2 and the discharge pipe 12 is close to the first electric valve 21.

[0020] During the specific implementation of the device, in the normal resin feeding operation, the first electric valve 21 and the second electric valve 22 are opened, the hot water component does not work, and the third electric valve 31 and the fourth electric valve 43 are closed. At this time, under the action of the metering pump 1, the resin in the feeding tank is quantitatively transported to the mixing tank; when the inner wall of the guide pipe 2 needs to be cleaned, the first electric valve 21 and the second electric valve 22 are closed, the third electric valve 31 and the fourth electric valve 43 are opened, and the hot water component works to pass external hot water under high pressure into the guide pipe 2. As the hot water flushes the inner wall of the guide pipe 2, the residual material attached to the inner wall of the guide pipe 2 flows out of the discharge pipe 42 together with the hot water.

[0021] Embodiment 2:

[0022] To avoid damage to the material guide tube 2 during use and affect the normal resin feeding operation; refer to the attached Figure 2 As shown, there are two material guide pipes 2 and they are connected to the discharge pipe 12 through a tee 5. When one of the material guide pipes 2 is damaged, the first electric valve 21 on the material guide pipe 2 is closed, the material feeding operation of the material guide pipe 2 is stopped, and the first electric valve 21 on the other material guide pipe 2 is opened to carry out the material feeding operation.

[0023] Embodiment 3:

[0024] In a low temperature environment, the resin is easy to solidify. The solidified resin not only increases the difficulty of feeding, but also adheres to the inner wall of the guide tube 2. From this perspective, refer to the attached Figure 3 As shown, a heating belt 6 is wound around the outside of the material guiding pipe 2, and the heating belt 6 heats the material guiding pipe 2 in a low temperature environment.

[0025] The above shows and describes the basic principles, main features and advantages of the utility model.
