Technical Field
[0001] This invention relates to the field of cement filtration technology, specifically to a filtration device for unloading bulk cement trucks. Background Technology
[0002] Currently, bulk cement trucks are specialized equipment for bulk cement transport. They connect cement silos with bulk cement transport vehicles and achieve automated or semi-automated delivery of bulk cement through a series of interlocking control devices. The bulk cement is then unloaded by the truck after being transported to the designated location. However, during long-term transportation or while waiting to unload the bulk cement, a small amount of cement in the tank may solidify. This is especially true when the mixing ratio of bulk cement is not coordinated. During transportation, the rotation of the cement tank by the bulk cement truck cannot fully tumble and mix the cement in the tank, causing it to solidify.
[0003] To address these technical problems, we propose a filtration device specifically designed for unloading bulk cement trucks. Summary of the Invention

[0058] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0059] See Figures 1 to 9 Shown:
[0060] A filtration device for unloading bulk cement trucks includes a feed pipe 1, a filtration mechanism 2, a discharge pipe 3, and an auxiliary feeding unit 4.
[0061] The feed pipe 1 is coaxially mounted on top of the filter mechanism 2 to introduce bulk cement;
[0062] The discharge conduit 3 is coaxially mounted at the bottom of the filter mechanism 2 to discharge the cement filtered by the filter mechanism 2;
[0063] The auxiliary feeding unit 4 is installed inside the filtration mechanism 2 to accelerate the filtration of bulk cement;
[0064] The filtration mechanism 2 also includes an upper chamber 21, a filtration unit 22, and a lower chamber 23;
[0065] The upper chamber 21 and the lower chamber 23 are detachably connected, and the upper chamber 21 and the lower chamber 23 are assembled to form a filter bucket;
[0066] The filter unit 22 is coaxially and detachably installed in the upper chamber 21 to filter the bulk cement entering the filter chamber 24.
[0067] In operation, when the bulk cement truck is unloading bulk cement, the feed pipe 1 is first connected to the discharge end of the bulk cement truck. The cement being discharged can enter the filter chamber 24 through the feed pipe 1 and be filtered by the filter unit 22 to remove any lumps of cement. The filtered bulk cement will then be automatically conducted towards the lower chamber 23 under the action of gravity, and will be re-aggregated in the lower chamber 23 before being guided away from the lower chamber 23 through the discharge pipe 3.
[0068] See Figure 4 and Figure 5 Shown:
[0069] The filter unit 22 includes a filter chamber 24, a quick-release connector 25, and a material storage chamber 26;
[0070] The quick-release connector 25 is coaxially and fixedly installed inside the top of the upper compartment 21;
[0071] The filter chamber 24 is coaxially and detachably mounted on the quick-release connector 25;
[0072] The material storage bin 26 is coaxially and pluggably installed at the bottom of the filter bin 24 to store clumped cement.
[0073] In operation, the filter chamber 24 is detachably mounted on the quick-release connector 25. Since the mesh openings on the filter chamber 24 are uniform, when it is necessary to change to a different mesh size, the operator only needs to remove the lower chamber body 23 and then replace the filter chamber 24 with the required mesh size. The material storage chamber 26 is used to store the cement lumps filtered through the filter chamber 24, so that they can be removed together later.
[0074] See Figure 5 Shown:
[0075] The filter chamber 24 includes a calibration port 241, a grip handle 242, and a snap-fit protrusion 243;
[0076] A calibration port 241 is provided through the bottom of the filter chamber 24;
[0077] Two sets of grip handles 242 are provided, and the two sets of grip handles 242 are arranged opposite to each other on the lower surface of the filter chamber 24;
[0078] There are three sets of snap-fit protrusions 243. The three sets of snap-fit protrusions 243 are equally spaced outside the filter chamber 24, and all three sets of snap-fit protrusions 243 are located close to the top of the filter chamber 24.
[0079] The calibration socket 241 is used to perform auxiliary calibration of the material storage bin 26 when it is put back, so as to ensure that the material storage bin 26 can be accurately inserted back into the filter bin 24. The two sets of grip handles 242 are used to facilitate the gripping of the filter bin 24 by the staff when replacing the filter bin 24.
[0080] See Figure 6 Shown:
[0081] The quick-release connector 25 includes a retaining ring 251, an overlapping ring 252, a snap-fit groove 253, and a notch 254;
[0082] The fixing ring 251 is coaxially and fixedly installed on the top of the upper compartment 21;
[0083] A lap ring 252 is also coaxially arranged inside the fixed ring 251. The lap ring 252 is arranged near the bottom of the fixed ring 251 to form an annular step with the fixed ring 251.
[0084] The snap-fit grooves 253 are formed from top to bottom on the upper surface of the overlapping ring 252. There are three sets of snap-fit grooves 253, and the three sets of snap-fit grooves 253 and the three sets of snap-fit protrusions 243 are set one-to-one.
[0085] Three sets of notches 254 are provided, and the three sets of notches 254 are equally spaced from top to bottom on the overlapping ring 252. The three sets of notches 254 and the three sets of snap-fit grooves 253 are arranged alternately.
[0086] In operation, when the filter chamber 24 needs to be replaced, the operator only needs to hold the two grip handles 242 to lift and rotate the filter chamber 24, so that the three sets of snap-fit protrusions 243 fixed on the top side of the filter chamber 24 rotate to the corresponding three sets of notches 254, thereby removing and replacing the filter chamber 24, thus realizing the quick disassembly and assembly of the filter chamber 24.
[0087] See Figure 5 and Figure 7 Shown:
[0088] The material storage bin 26 includes a calibration insert 261, a column 262, and a gripping part 263;
[0089] The calibration pin 261 is fixedly installed at the bottom of the material storage bin 26, and the calibration pin 261 is coaxially arranged with the calibration insertion hole 241.
[0090] The column 262 is coaxially fixedly installed in the middle of the material storage bin 26, and the top of the column 262 is also coaxially fixedly installed with a gripping part 263.
[0091] In operation, when it is necessary to empty the accumulated material in the storage bin 26, the operator only needs to hold the gripper 263 to pull the storage bin 26 away from the filter bin 24. The calibration pin 261 is used to ensure that when the storage bin 26 is put back into the filter bin 24, it can be accurately inserted back into the bottom of the filter bin 24. The storage bin 26 is calibrated by the calibration pin 261 and the calibration hole 241, so as to ensure that the screen holes on the storage bin 26 can correspond one-to-one with the screen holes on the filter bin 24, so as to avoid affecting the subsequent filtration work.
[0092] See Figure 3 Shown:
[0093] The auxiliary feeding unit 4 includes a dust removal auxiliary blower 41 and a conveying auxiliary blower 42;
[0094] The dust removal auxiliary blower 41 is coaxially fixedly installed at the top of the upper chamber 21, with the output end of the dust removal auxiliary blower 41 facing the inner wall of the filter chamber 24.
[0095] The conveying aid blower 42 is fixedly installed on one side of the discharge pipe 3 to assist the discharge pipe 3 in discharging the material.
[0096] In operation, the dust removal and blowing aid 41 can effectively accelerate the filtration speed of bulk cement in the filter chamber 24. The air pressure can promptly blow away the bulk cement adhering to the inner wall of the filter chamber 24, avoiding material accumulation and jamming, which would affect the final discharge speed.
[0097] See Figure 8 Shown:
[0098] The dust removal auxiliary blowing device 41 includes an air storage ring 411, an air source inlet 412, and an air guide nozzle 413;
[0099] The air storage ring 411 is coaxially fixedly installed inside the upper chamber 21 by a fixing bracket;
[0100] The air source inlet 412 is fixedly installed at the upper end of the air storage ring 411, and the air source inlet 412 passes through the upper chamber 21 and is set towards the outside of the upper chamber 21.
[0101] The air guide nozzle 413 is vertically positioned directly below the air storage ring 411, and multiple sets of air guide nozzles 413 are equidistantly arranged along the axis of the air storage ring 411.
[0102] In operation, when bulk cement is being filtered through the filter unit 22, the air source inlet 412 is connected to an external air source, allowing the external air source to be conducted through the air source inlet 412 to the inside of the air storage ring 411 and finally discharged towards the inner wall of the filter chamber 24 through multiple sets of air guide nozzles 413, thereby achieving the removal of bulk cement adhering to the inner wall of the filter chamber 24.
[0103] See Figure 9 Shown:
[0104] The conveying booster 42 includes an air guide bend 421 and an air source generator 422;
[0105] The side walls of the air guide bend 421 and the discharge duct 3 are connected;
[0106] The air source generator 422 is located at the air inlet end of the air guide bend 421.
[0107] In operation, when the filtered bulk cement is re-aggregated through the lower silo 23 and discharged through the discharge conduit 3, the air source generator 422 operates by inputting air into the air guide bend 421. The air source is discharged in the same direction as the material discharge direction of the discharge conduit 3 after passing through the air guide bend 421, thereby assisting the discharge conduit 3 in pushing out the material and preventing the bulk cement from getting blocked in the discharge conduit 3. The air source is conducted through the air guide bend 421, which can effectively prevent the material from flowing towards the air source generator 422 along the discharge conduit 3.
[0108] This application can effectively filter out lumpy cement, and the required filter mesh size can be changed as needed.
[0109] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
