[0030] Embodiment 1

[0031] This embodiment provides an anti-segregation raw sand bin, see Figures 1 to 3 The anti-segregation raw sand bin includes a bin 180 , a partition plate 160 , a material guide pipe 130 and a flow valve 140 .

[0032] The partition plate 160 is disposed in the material bin 180 , and the partition plate 160 divides the material bin 180 into a plurality of material discharge channels;

[0033] One end of the material guide pipe 130 is connected to the material discharge channel. There are multiple material guide pipes 130, and each material discharge channel is connected to at least one material guide pipe 130. One end of the material discharge channel away from the material guide pipe 130 is a loading end for loading materials, and one end of the material guide pipe 130 away from the material discharge channel is a discharging end for discharging materials.

[0034] The flow valve 140 is disposed on the material guiding pipe 130 , and the flow valve 140 is used to adjust the flow of the material guiding pipe 130 .

[0035] When in use, the raw sand first passes through multiple feeding channels, where the raw sand can be separated, thereby achieving a certain anti-segregation effect. Then the raw sand enters the guide pipe 130. Since the material composition of the raw sand in different feeding channels is different, the flow valve 140 corresponding to the guide pipe 130 can be controlled according to the material composition in the different guide pipes 130. This can achieve a material ratio of the raw sand flowing out of the guide pipe 130 after mixing that is closer to the preset ratio, thereby effectively preventing the segregation of the raw sand from having an adverse effect on the material ratio.

[0036] In actual operation, the flow rate of the flow valve 140 can be adjusted by a calibration method for raw sand with different material ratios, or the flow rate of the flow valve 140 can be adjusted by the material ratio in different material guide pipes 130 actually detected during use.

[0037] Specifically, if the calibration method is adopted, firstly, the material of a specific ratio is transmitted through multiple material discharge channels, and then passes through different material guide pipes 130, and the ratios of different materials in different material guide pipes 130 are detected, and then the ratios of the adjustment flow of different flow valves 140 are obtained by calculation, and the above method is repeated many times to finally obtain an average ratio of the adjustment flow of the flow valve 140, and then when the material of this specific ratio uses this raw sand bin, the ratio of the adjustment flow of the flow valve 140 can be adjusted according to the obtained average ratio of the adjustment flow of the flow valve 140. This method is suitable for the transmission of a limited number of materials of specific ratios.

[0038] If various adjustments are made in the used garage, it is necessary to detect the ratio of different materials in different material guide pipes 130 in real time, and then adjust the ratio of the adjustment flow of different flow valves 140 through real-time calculation, so as to realize the use of materials with unspecified ratios.

[0039] Optionally, in the present embodiment, the partition plate 160 is provided with a through hole 120 penetrating the partition plate 160 , and a plurality of through holes 120 are provided, and the plurality of through holes 120 are distributed at intervals on the partition plate 160 .

[0040] The through holes 120 on the dividing plate can allow the raw sands in different material discharge channels to be mixed with each other, thereby effectively promoting the reduction of the differences between the raw sands and further reducing the segregation of the raw sands in the material discharge channels.

[0041] Optionally, in the present embodiment, four partition plates 160 are provided, and the four partition plates 160 form a cross shape, and the four partition plates 160 divide the silo 180 into four material discharge channels.

[0042] By setting the partition plate 160 to a cross shape, the silo 180 can be divided into four discharge channels with the same cross-sectional area, so that the raw sand in different discharge channels can be roughly the same, thereby preventing the situation where too much raw sand accumulates in some discharge channels and too little raw sand accumulates in some discharge channels.

[0043] Optionally, in this embodiment, a ceiling 110 is further included. The ceiling 110 is arranged on one end of the silo 180 close to the loading end. A guide surface is arranged on the ceiling 110, and the guide surface is used to guide the material into the four unloading channels.

[0044] The ceiling 110 can guide the raw sand into the four material discharge channels when the raw sand is put into the silo 180.

[0045] Optionally, in this embodiment, the ceiling 110 is configured to be conical, the side of the ceiling 110 is a guide surface, the top surface of the ceiling 110 is configured to be on the side away from the silo 180, and the bottom surface of the ceiling 110 covers partial areas of all material discharge channels respectively.

[0046] The conical ceiling 110 can allow the raw sand to be dispersed more evenly through the ceiling 110 and into the four material discharge channels.

[0047] It should be pointed out that, when in use, the raw sand needs to be discharged from directly above the ceiling 110 , so that the raw sand can be dispersed as evenly as possible on the ceiling 110 .

[0048] Optionally, in this embodiment, a collecting bin 150 is further included, and the collecting bin 150 is connected to the discharge ends of all the material guiding pipes 130 .

[0049] The raw sand in all the material guide pipes 130 flows into the collecting bin 150 for collection. After being collected in the collecting bin 150, the raw sand in multiple different material guide pipes 130 can be mixed, so that the material ratio in the raw sand flowing out of the collecting bin 150 is closer to the material ratio in the raw sand put into the silo 180, thereby further reducing the segregation of the raw sand.

[0050] Optionally, in the present embodiment, an opening is provided on the end of the collecting bin 150 away from the material guiding tube 130 .

[0051] The opening on the collecting bin 150 away from the material guide pipe 130 can facilitate the transfer of raw sand out of the collecting bin 150 .

[0052] Optionally, in this embodiment, a control valve 170 is further included. The control valve 170 is connected to the collecting bin 150, and the control valve 170 is used to control the opening and closing of the opening.

[0053] The control valve 170 is used to control the discharge of raw sand. The raw sand needs to be collected in the collection bin 150 first, and then the control valve 170 is opened to discharge it, so the control valve 170 needs to be opened and closed intermittently.

[0054] Optionally, in this embodiment, a controller is also included, which is electrically connected to the control valve 170 and the multiple flow valves 140 respectively. The control valve 170 is used to control the opening degree of the multiple flow valves 140 respectively and control the opening and closing of the control valve 170.

[0055] The flow valve 140 and the control valve 170 are controlled by a controller, so that the flow valve 140 and the control valve 170 can be controlled conveniently.

[0056] It should be pointed out that in the prior art, the method of controlling the flow valve 140 and the control valve 170 by using a controller is already very mature, and the specific operation method thereof will not be described in detail here.

[0057] Optionally, in this embodiment, the controller is one of a PLC, a PC or a single chip microcomputer.

[0058] By using a PLC or the like as a controller, the flow valve 140 or the control valve 170 can be conveniently controlled.

[0059] PLC, PC and single-chip microcomputer are all commonly used devices for control in the prior art, and their specific operation methods will not be repeated here.

[0060] The working principle of the anti-segregation raw sand bin provided in the present embodiment is that, when working, the raw sand first passes through a plurality of discharge channels, in which the raw sand can be separated, thereby achieving a certain anti-segregation effect, and then the raw sand enters the material guide pipe 130. Since the material composition of the raw sand in different discharge channels is different, the flow valve 140 corresponding to the material guide pipe 130 can be controlled according to the material composition in the different material guide pipes 130, so that the proportion of the raw sand flowing out of the material guide pipe 130 after mixing can be closer to the preset proportion, thereby effectively preventing the segregation of the raw sand from having an adverse effect on the material proportion.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
