The energy-carrying medium is hindered by the adhesion layer composed of material particles and moisture that are attached to the surface of the lining plates. In this way, a pressure layer is formed at the bonding surface. Under the action of pressure, the material particles that are embedded with the surface of the lining plates are pushed out of the grooves on the surface of the lining plates.

[0032] Please see the appendixFigures 1-5 The present invention provides a material hopper 30 wall-adhesion removal device in one embodiment, comprising a pressure-holding pipe 10 and at least one liner unit 20, the specific scheme of which is as follows:

[0033] The liner unit 20 includes a pressure pad 210, a connecting pipe 220, and multiple interconnected liner plates 230. The liner plates 230 are connected to the inner side of the baffle plate 310 of the discharge hopper 30. The pressure pad 210 is connected between the liner plate 230 and the baffle plate 310 of the discharge hopper 30. The pressure pad 210 has multiple interconnected medium pools inside. The baffle plate 310 of the discharge hopper 30 has a through hole for the connecting pipe 220 to pass through. The first end of the connecting pipe 220 passes through the pressure pad 210 and extends into the medium pool. The pressure holding pipe 10 is connected to the second end of the connecting pipe 220 and is disposed on the outside of the discharge hopper 30. The pressure holding pipe 10 is internally connected to the connecting pipe 220. The pressure holding pipe 10 has an inlet 110 for the flow of energy-carrying medium. Each liner plate 230 has multiple overflow holes communicating with the medium pool.

[0034] Specifically, the hopper 30 wall-adhesion removal device in this application includes a pressure-holding pipe 10 and at least one liner unit 20. The number of liner units 20 can be set according to the size and area of ​​the baffle plate 310 of the hopper 30 to ensure that the inner side of the baffle plate 310 can be covered, thereby ensuring a better wall-adhesion removal effect. For example, in a preferred embodiment of this application, the number of liner units 20 in a hopper 30 wall-adhesion removal device is three. The three liner units 20 are arranged side by side and spliced ​​together to jointly remove the wall-adhesion.

[0035] The liner unit 20 includes a pressure pad 210, a connecting pipe 220, and multiple interconnected liner plates 230. The pressure pad 210 serves as an intermediate carrier for the flow of the energy-carrying medium, while the liner plates 230 replace the baffle plate 310 to directly contact the sintering raw materials. Therefore, the liner plates 230 are connected to the inside of the baffle plate 310 of the discharge hopper 30, and the pressure pad 210 is tightly fitted between the baffle plate 310 and the liner plates 230 when the liner plates 230 are connected to the baffle plate 310. For the introduction of the energy-carrying medium, a medium pool (not shown in the figure) is provided inside the pressure pad 210. The energy-carrying medium is obtained by connecting the pressure-holding pipe 10 through the connecting pipe 220. After the energy-carrying medium flows into the pressure-holding pipe 10, under pressure, the energy-carrying medium flows into the medium pool through the connecting pipe 220. The liner 230 is pre-drilled with multiple overflow holes (not shown in the figure) during processing. Thus, under continuous pressure, the energy-carrying medium in the full medium pool seeps out through the overflow holes onto the surface of the liner 230. During seepage, it is hindered by the adhesion layer composed of material particles 420 and water 430 attached to the surface of the liner 230. At the interface between the energy-carrying medium and the adhesion layer, a layer is formed. Pressure layer 410 is formed, and under continuous pressure, the material particles 420 that are interlocked with the surface (grooves, sharp corners) of the liner 230 are pushed out of the grooves on the surface of the liner 230. This reduces adhesion, and the adhesive layer composed of material particles 420 and moisture 430 gradually peels off from the surface of the liner 230, thereby achieving the purpose of removing adhesion from the bucket wall. It is worth mentioning that since the grooves and sharp corners on the surface of the liner 230 are produced because a completely flat surface cannot be guaranteed during manufacturing, this is a micro-power technology adopted from a microscopic perspective. Therefore, the overflow hole... The diameter can be set within 5 to 15 nm, and the multiple overflow holes are evenly distributed to ensure the uniformity of the distribution when the energy-carrying medium seeps out. The energy-carrying medium can be gas or liquid, specifically steam or water. Water forms an isolation layer on the surface of the liner to prevent material adhesion. Since the material particles themselves have a high water content, the overflowing water will not cause new adhesion problems and will destroy the adhesion layer under pressure to push out the material particles. Steam can also have this effect, and steam can also be converted into water after liquefaction as a pressure layer. Those skilled in the art can select other media according to actual needs.

[0036] In a preferred embodiment of the present invention, the number of liner plates 230 in each liner plate unit 20 is six; wherein, three liner plates 230 are arranged side by side as a row of liner plate 230 groups, and the number of liner plate 230 groups in each liner plate unit 20 is two rows spliced ​​together to form a rectangular cross section.

[0037] It should be noted that the six lining plates 230 are easy to install by splicing them together. Three lining plates 230 can be set in a row to form a matrix arrangement of two rows and three columns. When installed on the baffle plate 310, they should be arranged reasonably according to the cross-sectional dimensions of the baffle plate 310.

[0038] In a preferred embodiment of the present invention, the pressure pad 210 includes a bottom sealing portion 211, a circumferential isolation portion 212, a longitudinal isolation portion 213, and a transverse isolation portion 214. The bottom sealing portion 211 is disposed inside the baffle plate 310 of the hopper 30. The circumferential isolation portion 212, the longitudinal isolation portion 213, and the transverse isolation portion 214 are all connected between the bottom sealing portion 211 and the liner plate 230. The circumferential isolation portion 212 is arranged around the bottom sealing portion 211 in the circumferential direction. The longitudinal isolation portion 213 is disposed at the longitudinal joint between two rows of liners 230. The transverse isolation portion 214 is disposed at the transverse joint between the liners 230. The longitudinal isolation portion 213, the transverse isolation portion 214, and the circumferential isolation portion 212 together form the medium pool.

[0039] It should be noted that the polypressure pad 210 can also be rectangular to match the liner unit 20. The bottom sealing part 211 serves as the base plate, and the circumferential isolation part 212 separates the liner 230 and the bottom sealing part 211 to form a space for carrying the energy-carrying medium. Therefore, the circumferential isolation part 212 is arranged around the circumference of the bottom sealing part 211 to form a surrounding enclosure. The longitudinal isolation part 213 and the transverse isolation part 214 are used to divide the entire space carrying the energy-carrying medium into multiple medium pools. Both the longitudinal isolation part 213 and the transverse isolation part 214 are arranged on the liner 230. At the splice seam of 30, a medium pool is set under each liner 230 to facilitate the seepage of the energy-carrying medium in a single medium pool from the overflow hole of the corresponding liner 230. It should be noted that the longitudinal direction refers to the length direction of the rectangular polypressure pad 210, and the transverse direction refers to the width direction of the rectangular polypressure pad 210. Combined with the two-row, three-column distribution of the liner 230, the splice seam between two rows of liner 230 is a longitudinal splice seam, and the longitudinal isolation part 213 is set at the longitudinal splice seam. The splice seam between two adjacent columns of liner 230 is a transverse splice seam, and the transverse isolation part 214 is set at the transverse splice seam.

[0040] It is worth mentioning that the thickness of the bottom sealing part 211 as the base plate can be set to 1 / 3 of the thickness of the entire polypressure pad 210, while the thickness of the circumferential isolation part 212, the longitudinal isolation part 213, and the transverse isolation part 214 can all be set to 2 / 3 of the thickness of the entire polypressure pad 210, thereby forming the required thickness of the medium pool. The specific thickness can also be adjusted as needed.

[0041] In a preferred embodiment of the present invention, the longitudinal isolation portion 213 is provided with a plurality of transverse pressure equalizing holes 2131 arranged equidistantly along the longitudinal direction, and the transverse isolation portion 214 is provided with a plurality of longitudinal pressure equalizing holes 2141 arranged equidistantly along the transverse direction.

[0042] It is worth noting that by setting multiple pressure equalization holes to achieve connectivity between the various medium pools, the uniform distribution of the flowing energy medium is ensured, and the pressure is also evenly distributed while the various medium pools are connected. Specifically, the transverse pressure equalization hole 2131 is used to connect the medium pools between the two rows of liner plates 230, while the longitudinal pressure equalization hole 2141 is used to connect the medium pools between the three rows of liner plates 230.

[0043] In a preferred embodiment of the present invention, the first end of the connecting pipe 220 is provided with a flange 221 protruding outward along its own radial direction, and the connecting pipe 220 is engaged with the bottom sealing part 211 through the flange 221 to connect with the pressure pad 210.

[0044] It is worth noting that the flange 221 facilitates the snapping of the first end of the connecting pipe 220 onto the bottom seal 211, thereby making the connection and installation convenient through snapping. It also allows the first end of the connecting pipe 220 to extend into the medium pool, facilitating the inflow of the energy-carrying medium.

[0045] Furthermore, each of the four corners of the liner 230 is recessed to form an arc-shaped hole 231, and the adjacent arc-shaped holes 231 surround each other to form a first bolt hole. The longitudinal isolation part 213 and the transverse isolation part 214 are respectively provided with second bolt holes corresponding to each of the first bolt holes. The baffle plate 310 of the discharge hopper 30 is provided with a third bolt hole corresponding to the second bolt hole. The liner 230 is fixedly connected to the baffle plate 310 of the discharge hopper 30 by bolts passing through the first bolt hole, the second bolt hole, and the third bolt hole and by nuts.

[0046] It should be noted that the arc-shaped holes 231 at each corner are quarter-circle holes. Thus, when four lining plates 230 are spliced ​​together to form a square, the center of the square is surrounded by four quarter-circle holes (arc-shaped holes 231) to form a circular first bolt hole, which is convenient for bolt connection to install on the baffle plate 310. This facilitates easy disassembly and assembly, and easy maintenance and replacement later. The second bolt hole and the third bolt hole are pre-processed to facilitate bolt penetration. After penetration, they are fastened with nuts on the outside of the baffle plate 310. The corresponding setting here means that the diameter of the first bolt hole, the second bolt hole, and the third bolt hole are consistent along the thickness direction of the baffle plate 310 and are set on the same axis. It can be understood that the two spliced ​​lining plates 230 on the periphery form a semi-circular bolt hole for bolt penetration, and the quarter-circle holes at the corners can also usually be tightened by bolts.

[0047] This application also provides a discharge hopper 30, including two baffle plates 310 disposed opposite to each other on both sides of the discharge port, and a discharge hopper 30 wall-adhesion removal device as described above. Each baffle plate 310 is provided with a discharge hopper 30 wall-adhesion removal device. The liner plate 230 of the discharge hopper 30 wall-adhesion removal device is connected to the inner side of the baffle plate 310, and the pressure pad 210 of the discharge hopper 30 wall-adhesion removal device is connected between the liner plate 230 and the baffle plate 310. A through hole is provided on the baffle plate 310, and the second end of the connecting pipe 220 of the discharge hopper 30 wall-adhesion removal device passes through the through hole and extends out of the baffle plate 310.

[0048] It should be noted that the hopper 30 in this application is in the form of a panel with two inclined sides, and therefore includes two baffle plates 310. The bottom end of the baffle plate 310 is directly surrounded by two other vertical wall plates to form a discharge port. Therefore, considering the comprehensiveness of the wall-adhesion removal effect, a wall-adhesion removal device of the hopper 30 needs to be installed above the baffle plates 310 on both sides. During installation, the pressure pad 210 is placed on the inside of the baffle plate 310, the bolt holes are aligned, and then the liner plate 230 is tightened and fixed by bolts to fix the pressure pad 210 between the liner plate 230 and the baffle plate 310. The connecting pipe 220 of the wall-adhesion device of the hopper 30 is also inserted into the through hole of the baffle plate 310, so as to extend to the outside of the hopper 30 for the installation and connection of the pressure-holding pipe 10.

[0049] Furthermore, each of the hopper 30 wall-adhesion removal devices contains three liner units 20, which are sequentially arranged side by side along the inclined extension direction of the baffle plate 310.

[0050] It is understood that the three liner units 20 are spliced ​​together on their own long sides. Thus, three through holes need to be opened on the baffle plate 310 at the same time so that the connecting pipes 220 of the three liner units 20 can pass through them respectively. The second ends of the three connecting pipes 220 are all connected to the inside of the pressure holding pipe 10. Under pressure, the energy-carrying medium in the pressure holding pipe 10 flows into the three liner units 20 through the three connecting pipes 220 respectively. It is worth mentioning that, in a preferred embodiment of this application, the pressure in the pressure holding pipe 10 can be maintained between 0.3 and 0.5 MPa. The specific value can be set by those skilled in the art according to the actual situation.

[0051] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
