[0002] In most industries such as chemical, pharmaceutical, and energy, solid particulate matter is often transported. Conventional transport methods include open and closed types. The open type can be transported by crawler belts or screws, and the closed type can be air-blown or vacuum-sucked. These transport processes have a common feature that solid materials are transported at room temperature. However, when the transported material is a high-temperature solid, the transport process will have to consider the cooling of the solid material, reducing the loss rate, and improving the transportation efficiency.

The separated liquid returns to the storage tank for reuse. The high-temperature solid collection and conveying system can realize continuous feeding of high-temperature solids, and the receiving and conveying of solids are smoothly connected. The operation of the entire system can be fully automatic, safe, efficient, economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention replenishes liquid to the bottom of the cylinder through a storage tank, and then high-temperature solid materials enter the cylinder filled with low-temperature liquid, and the carrier liquid drives their flow, which can greatly reduce the movement and breakage of solid particles, and then mix with the liquid and cool down. Under the action of the liquid, the solid materials enter the buffer storage tank in the form of particles, and the large particles are deposited at the bottom of the buffer storage tank under the action of gravity, and can be discharged from the bottom outlet of the buffer storage tank. The overflowed liquid is then separated from the tiny particle impurities and liquid through the solid-liquid separation device, and the impurities will be discharged from the system in the form of sludge. The separated liquid returns to the storage tank for reuse. The high-temperature solid collection and conveying system can realize continuous feeding of high-temperature solids, and the receiving and conveying of solids are smoothly connected. The operation of the entire system can be fully automatic, safe, efficient, economical and practical.

[0037] The specific working process of the high temperature solid collection and transportation system in this embodiment is as follows:

[0038] Before the system works, the states of the components in the system are as follows: the upper manhole 6 is closed, the counterweight 7 is in a free state, the discharge plate 8 is in a free state, the cylinder pressure detection 9 is open, the cylinder high position detection 10 is open, the cylinder low position detection 11 is open, the side manhole 12 is closed, the cylinder side delivery pump 13 is stopped, the No. 1 switch valve 14 is open, the No. 1 control valve 15 is closed, the solid-liquid separation device 16 is open, the No. 2 switch valve 17 is open, the No. 2 control valve 18 is closed, the No. 3 switch valve 20 is open, the delivery pump pressure detection 21 is open, the storage tank side delivery pump 22 is closed, the No. 4 switch valve 23 is open, the No. 5 switch valve 25 is open, the No. 3 control valve 26 is closed, the No. 6 switch valve 28 is closed, the airbag pressure detection 29 is open, the airbag 30 is filled with gas, the buffer tank high position detection 31 is open, the buffer tank low position detection 32 is open, the buffer tank 33 is empty, the No. 7 switch valve 34 is open, and the No. 4 control valve 35 is closed;

[0039] The No. 1 control valve 15 is opened, the No. 2 control valve 18 is opened, and the tank-side delivery pump 22 is opened. Liquid begins to be filled into the bottom of the cylinder 1. After a period of time, the liquid will fill the cylinder 1 and flow back into the storage tank 24 through the upper reflux port. The tank-side delivery pump 22 stops, the No. 2 control valve 18 is closed, and the No. 1 control valve 15 is closed.

[0040] The high-temperature solid enters the upper part of the cylinder 1 through the feed pipe 3 and is mixed with the liquid and cooled.

[0041] Open the No. 1 control valve 15 and the cylinder side delivery pump 13, and the solid particles are brought into the lower half of the cylinder 1 through the discharge plate 8 due to the flow of liquid.

[0042] The solid particles entering the cylinder 1 will gradually increase over time and will be detected by the cylinder low-level detection 11 and the cylinder high-level detection 10 in sequence.

[0043] When the cylinder high position detection 10 detects solid particles, the cylinder side delivery pump 13 is stopped and the No. 1 control valve 15 is closed; then the No. 2 control valve 18 is opened, the No. 3 control valve 26 is opened, and the tank side delivery pump 22 is started. At this time, the flow of liquid will drive the discharge plate 8 upward to close the flow channel here to achieve the purpose of isolation.

[0044] As the pressure in the lower part of the cylinder 1 increases, the solid particles retained in the lower part of the cylinder 1 will be carried by the liquid to the buffer storage tank 33 .

[0045] As time goes by, the solid particles at the bottom of the cylinder 1 gradually decrease and are detected by the cylinder low position detection 11. After a period of time, the solid particles at the bottom will be transported. Close the tank side delivery pump 22, close the No. 2 control valve 18, and close the No. 3 control valve 26.

[0046] Repeat steps 4 to 8 above;

[0047] The liquid entering the buffer tank 33 will flow out through the overflow port at the top of the buffer tank 33 and return to the storage tank 24 after passing through the solid-liquid separation device 16. The tiny particles entrained by the liquid are separated and discharged from the system.

[0048] When the buffer tank high level detection 31 detects solid particles, the No. 4 control valve 35 is opened to discharge the solids from the buffer tank 33, and the No. 4 control valve 35 is closed when the buffer tank low level detection 32 detects no solids.

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
