Description

Technical Field

[0001] The invention relates to the field of slurry preparation, and in particular to a slurry preparation system. Background Art

[0002] The slurry for ceramic tiles is made by mixing water, mud, stone particles, etc. according to a process formula, and then grinding and mixing them in a ball mill. Specifically, the existing ball mill includes a preparation container and a plurality of grinding balls, wherein the preparation container has an inlet, an outlet, and a preparation space connecting the inlet and the outlet. Raw materials such as water, mud, and stone particles are fed into the preparation space of the ball mill from the inlet through a conveyor belt. The grinding balls are arranged in the preparation space, and when the preparation container is driven to rotate at a high speed, the raw materials such as water, mud, and stone rub, collide, and squeeze with the grinding balls until they are refined to the size required for making ceramic tiles. Although the existing ball mill can prepare qualified slurries, there are still many problems in the actual preparation process.

[0003] Specifically, the length extension direction of the preparation container of the ball mill is parallel to the horizontal plane, and the feed port of the ball mill cannot be opened during the preparation of the slurry. Therefore, before driving the preparation container to rotate, it is necessary to add raw materials such as water, mud and stone particles into the preparation space of the preparation container of the ball mill. Then the preparation container is rotated at high speed so that the mud and stone are ground to a qualified size and mixed evenly with water. However, the time required for grinding stone particles is much longer than the time required for grinding mud. In order to ensure that the stone particles are fully crushed and refined, it is usually necessary to rotate continuously for 12 hours. Since the feed port of the ball mill cannot be opened during the preparation of the slurry, the preparation container must carry all the raw materials for high-speed rotation operation, and the weight of the preparation container itself is very heavy, weighing tens of tons. In this way, not only the power requirements of the ball mill are very large, but also the power consumption is large, the preparation cost is high, and it is not conducive to environmental protection.

[0004] In addition, in the existing slurry preparation process, since the mud entering the preparation container is mixed with a large amount of impurities such as leaves and roots, the slurry passing through the ball mill needs to be manually filtered to pick out the impurities in the slurry to ensure the quality of the slurry. Such pulping equipment with a low degree of automation is highly dependent on operators, which not only causes heavy manpower load and high labor costs, but also makes it difficult to ensure the stability of slurry quality.

[0079] Refer to the instruction manual Figures 1 to 16A slurry preparation system 1000 according to a preferred embodiment of the present invention will be described in the following description, wherein the slurry preparation system 1000 includes a mud raw material production line 100, a stone powder production line 200 and a slurry mixing device 300, wherein the mud raw material production line 100 is used to prepare mud, and the stone powder production line 200 is used to prepare stone powder, and the mud raw material production line 100 and the stone powder production line 200 are respectively connected to the slurry mixing device 300 to respectively provide the mud raw material and the stone powder to the slurry mixing device 300. The mud prepared by the mud raw material production line 100 and the stone powder prepared by the stone powder production line 200 are uniformly mixed in the slurry mixing device 300 to prepare slurry, wherein the slurry can be used to manufacture tiles, etc.

[0080] Reference Figures 1 to 7 The mud raw material production line 100 includes at least one mud raw material feeder 110, a mud raw material crusher 120, a mud raw material conveyor belt 130, a mud raw material buffer machine 140, a first water tank 150, at least two mud raw material mixers 160, a mud raw material filter device 170 and a mud raw material storage tank 180. The mud raw material feeder 110 weighs and proportions the mud raw material, and the mud raw material crusher 120 crushes and refines the weighed mud raw material. The mud raw material passing through the mud raw material crusher 120 enters the mud raw material buffer machine 140 under the action of the mud raw material conveyor belt 130. After the water in the first water tank 150 and the mud raw material stored in the mud raw material buffer machine 140 enter the mud raw material mixer 160, the mud raw material mixer 160 stirs the mud raw material and water to obtain the mud. The prepared mud passes through the mud raw material filtering device 170 and is stored in the mud raw material storage pool 180 for subsequent mixing with the stone powder produced by the stone powder production line 200 to obtain the slurry. Preferably, the mud raw material buffer 140 also stores a debonding agent, and the debonding agent, the mud raw material and water are fully mixed to obtain the mud.

[0081] Specifically, refer to the attached Figure 2 and Figure 3The slurry raw material feeder 110 includes a slurry raw material weighing mechanism 111, a slurry raw material conveying mechanism 112 and a carrier 113, wherein the slurry raw material weighing mechanism 111 and the slurry raw material conveying mechanism 112 are arranged above the carrier 113 and the slurry raw material conveying mechanism 112 is located below the slurry raw material weighing mechanism 111, wherein the slurry raw material conveying belt 130 is held at the side of the carrier 113, and the height position of the slurry raw material conveying belt 130 is lower than the height position of the slurry raw material conveying mechanism 112.

When the mud raw material drop-out port 1112 is in the closed state, the mud raw material is held in the mud raw material weighing space 1111 of the mud raw material weighing mechanism 111 for weighing the weight of the mud raw material. Accordingly, when the mud raw material drop-out port 1112 is in the open state, the mud raw material held in the mud raw material weighing space 1111 of the mud raw material weighing mechanism 111 is allowed to automatically drop through the mud raw material drop-out port 1112 to the mud raw material conveying mechanism 112, so that the mud raw material is conveyed by the mud raw material conveying mechanism 112 toward the direction of the mud raw material conveying belt 130. Subsequently, based on gravity, the mud raw material can automatically drop from the mud raw material conveying mechanism 112 to the mud raw material conveying belt 130.

[0083] Optionally, the mud raw material conveyor belt 130 is held on one side of the mud raw material weighing mechanism 111 of the mud raw material feeder 110, and the mud raw material weighing mechanism 111 of the mud raw material feeder 110 pours the weighed raw material into the mud raw material conveyor belt 130 by flipping.

[0084] It is worth mentioning that the specific implementation of the slurry raw material feeder 110 is only an example. The slurry raw material feeder 110 only needs to be able to weigh the slurry raw material and transfer the weighed slurry raw material to the slurry raw material conveyor belt 130. In addition, the specific number of the slurry raw material feeder 110 is not limited. The slurry raw material feeder 110 can be implemented as one, two, three or more.

The mud raw material crusher 120 has a mud raw material crushing space 1201, and the entrance of the mud raw material crushing space 1201 of the mud raw material crusher 120 corresponds to the end of the mud raw material conveying mechanism 112 of the mud raw material feeder 110, and the outlet of the mud raw material crushing space 1201 corresponds to the mud raw material conveyor belt 130, so that the mud raw material conveying mechanism 112 can convey the mud raw material to the mud raw material crushing space 1201 of the mud raw material crusher 120, so as to allow the mud raw material to be crushed and refined in the mud raw material crushing space 1201 of the mud raw material crusher 120, which is conducive to subsequent uniform mixing, and the crushed and refined mud raw material can fall to the mud raw material conveyor belt 130 through the outlet of the mud raw material crushing space 1201 of the mud raw material crusher 120.

The mud raw material buffer barrel 141 has a mud raw material buffer chamber 1411 and a mud raw material inlet 1412 and a mud raw material outlet 1413 respectively connected to the mud raw material buffer chamber 1411, wherein the mud raw material inlet 1412 and the mud raw material outlet 1413 respectively form the upper part and the lower part of the mud raw material buffer barrel 141. The mud raw material distribution mechanism 142 has a mud raw material distribution space 1421 and two mud raw material distribution openings 1422 connected to the raw material distribution space 1421, and the mud raw material distribution mechanism 142 is arranged below the mud raw material buffer barrel 141 in such a way that the raw material distribution space 1421 can be connected to the mud raw material outlet 1413 of the mud raw material buffer barrel 141. The mud raw material conveyor belt 130 is allowed to be connected to the mud raw material cache cavity 1411 of the mud raw material cache barrel 141 through the mud raw material inlet port 1412 of the mud raw material cache barrel 141, so that the mud raw material conveyor belt 130 can convey the mud raw material to the mud raw material cache cavity 1411 through the mud raw material inlet port 1412 of the mud raw material cache barrel 141.

[0087] The mud raw material buffer barrel 141 can switch between a storage state and a discharge state. When the mud raw material buffer barrel 141 is in the storage state, the mud raw material outlet 1413 of the mud raw material buffer barrel 141 is closed. At this time, the mud raw material transported by the mud raw material conveyor belt 130 can be stored in the mud raw material buffer cavity 1411 of the mud raw material buffer barrel 141. Correspondingly, when the mud raw material buffer barrel 141 is in the discharging state, the mud raw material discharge port 1413 of the mud raw material buffer barrel 141 is opened. At this time, the mud raw material distribution space 1421 of the mud raw material distribution mechanism 142 is connected to the mud raw material buffer cavity 1411 of the mud raw material buffer barrel 141, and the mud raw material stored in the mud raw material buffer cavity 1411 of the mud raw material buffer barrel 141 enters the mud raw material distribution space 1421 of the mud raw material distribution mechanism 142 from the mud raw material discharge port 1413.

[0088] Continue to refer to the attached Figure 4The mud raw material distribution mechanism 142 includes a mud raw material distribution conveyor belt 1423 and a closed shell 1424, wherein the closed shell 1424 is covered on the mud raw material distribution conveyor belt 1423, and the mud raw material distribution space 1421 is formed between the mud raw material distribution conveyor belt 1423 and the closed shell 1424, and a mud raw material distribution opening 1422 is formed at each end of the mud raw material distribution conveyor belt 1423. The mud raw material distribution conveyor belt 1423 is drivably connected to the driving mechanism 143, and the driving mechanism 143 can drive the mud raw material distribution conveyor belt 1423 to move, and transport the mud raw material in the mud raw material distribution space 1421 to the mud raw material mixer 160. It can be understood that the driving mechanism 143 distributes the mud raw material falling into the raw material distribution space 1420 to different mud raw material mixers 160 by driving the mud raw material distribution conveyor belt 1423 to rotate in different directions.

[0089] Preferably, the driving mechanism 143 is arranged inside the closed shell 1424 of the mud raw material distribution mechanism 142, so that the sealing of the mud raw material buffer 140 can be ensured, thereby avoiding dust when the mud raw material buffer 140 caches and distributes the mud raw material, thereby ensuring the cleanliness of the air in the working environment.

[0090] It is worth mentioning that the type of the driving mechanism 143 is not limited in the slurry preparation system 1000 of the present invention. For example, the driving mechanism 143 may be a driving motor, or the driving mechanism 143 may be a combination of a driving motor and a gear set.

[0091] Reference Figure 1 and Figure 2 The two mud raw material mixers 160 are respectively arranged at the two ends of the conveyor belt 1421 of the mud raw material distribution mechanism 142, and the two mud raw material mixers 160 are respectively connected to the two mud raw material distribution openings 1422 of the mud raw material distribution mechanism 142 of the mud raw material buffer 140. The mud raw material distribution conveyor belt 1421 is driven by the driving mechanism 143 to move forward or backward, so that the mud raw material in the mud raw material distribution space 1421 can be distributed to different mud raw material mixers 160 through different mud raw material distribution openings 1422. In this way, when one mud raw material mixer 160 is in the process of mixing the mud raw material, the other mud raw material mixer 160 can be in the feeding state, which is conducive to improving the preparation efficiency of the slurry preparation system 1000.

[0092] Reference Figure 1 and Figure 2 The first water tank 150 is maintained at one side of the mud raw material buffer 140, and the first water tank 150 has a water storage chamber 1501, wherein the water storage chamber 1501 of the first water tank 150 can be connected to the mud raw material mixer 160 to allow the water in the water storage chamber 1501 of the first water tank 150 to be provided to the mud raw material mixer 160.

[0093] Preferably, after the water stored in the water storage chamber 1501 of the first water tank 150 is poured into the mud raw material mixer 160, the mud raw material buffer 140 then adds the mud raw material into the mud raw material mixer 160 to help reduce dust pollution.

[0094] Reference Figures 5 to 6B The mud raw material mixer 160 includes a mud raw material mixing barrel 161, a guide channel 162, a mud raw material stirring mechanism 163, a power mechanism 164 and an impurity collection well 165, wherein the mud raw material mixing barrel 161 has a mud raw material mixing chamber 1611 and a lower side opening 1612 and a plurality of side wall through holes 1613 respectively connected to the mud raw material mixing chamber 1611, wherein the guide channel 162 has a drainage opening 1621 and a drainage chamber 1622 connected to the drainage opening 1621, wherein the impurity collection well 165 has a side opening 1651 and a collection chamber 1652 connected to the side opening 1651.

[0095] The guide channel 162 is provided at one side of the mud raw material mixing barrel 161 in such a manner that the drainage chamber 1622 is connected to the lower opening 1612 of the mud raw material mixing barrel 161, and the drainage opening 1621 of the guide channel 162 is connected to the mud raw material distribution opening 1422 of the mud raw material distribution mechanism 142 of the mud raw material buffer 140. The water storage chamber 1501 of the first water tank 150 is connected to the drainage chamber 1622 of the guide channel 162. After passing through the drainage chamber 1622 of the guide channel 162, the water in the water storage chamber 1501 of the first water tank 150 and the mud raw material in the drainage chamber 1622 of the guide channel 162 enter the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 from the lower opening 1612 of the mud raw material mixing barrel 161.

[0096] The mud raw material stirring mechanism 163 is drivably connected to the power mechanism 164, and the mud raw material stirring mechanism 163 is installed above the mud raw material mixing barrel 161 in a manner of being held in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. The power mechanism 164 drives the mud raw material stirring mechanism 163 to rotate in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 to mix the mud raw material and water entering the mud raw material mixing chamber 1611.

[0097] The impurity collection well 165 of the mud raw material mixer 160 is arranged at the side of the mud raw material mixing barrel 161 in such a manner that the side opening 1651 is connected to the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. The side wall through hole 1613 of the mud raw material mixing barrel 161 connects the collecting chamber 1652 of the impurity collection well 165 and the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. When the power mechanism 164 stirs the mud raw material in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161, impurities such as leaves and roots in the mud raw material can enter the collecting chamber 1652 from the side opening 1651 of the impurity collection well 165.

[0098] Specifically, refer to the attached Fig. 6A and Figure 6B The mud material stirring mechanism 163 includes a first holding rod 1631, a first inner spiral 1632, at least two first outer spirals 1633 and a first retaining member 1634, wherein the first inner spiral 1632 spirally extends upward from the lower end of the first holding rod 1631, the middle of the first retaining member 1634 is arranged at the upper end of the first holding rod 1631, and each of the first outer spirals 1633 extends downward from the two ends of the first retaining member 1634 at intervals to the lower end connected to the first holding rod 1631. The cross section of the first outer spiral 1633 gradually decreases from top to bottom. The first outer spiral 1633 is located at intervals on the outside of the first inner spiral 1632.

[0099] The upper end of the mud raw material stirring mechanism 163 is drivably connected to the power mechanism 164, and the power mechanism 164 drives the first retaining rod 1631 to rotate, and drives the first inner spiral 1632 and the first outer spiral 1633 to rotate in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. Under the action of the first inner spiral 1632 and the first outer spiral 1633 of the mud raw material stirring mechanism 163, the water and the mud raw material in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 move upward in a spiral in the middle of the mud raw material mixing chamber 1611, and then fall to the bottom along the periphery of the mud raw material mixing chamber 1611, and the cycle is repeated so that the mud raw material is mixed evenly. The mud raw material collides with the first inner spiral 1632 and the first outer spiral 1633, which can not only stir the mud raw material evenly, but also make the mud raw material finer again. Impurities such as leaves and tree roots that follow the mud raw material into the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 also move from bottom to top under the action of the first inner spiral 1632 and the first outer spiral 1633. When the leaves and tree roots are driven to move to the side opening 1651 corresponding to the impurity collection well 165, under the action of centrifugal force, the leaves and tree roots and other impurities in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 are thrown from the side opening 1651 of the impurity collection well 165 into the collection chamber 1652 of the impurity collection well 165.

[0100] The side opening 1651 of the impurity collection well 165 is located above the side wall through hole 1613 of the mud raw material mixing barrel 161. Impurities such as leaves and tree roots that enter the collection chamber 1652 from the side opening 1651 of the impurity collection well 165 fall to the bottom of the collection chamber 1652 under the action of gravity, and the water that enters the collection chamber 1652 flows back from the side wall through hole 1613 of the mud raw material mixing barrel 161 to the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. This cycle is repeated so that impurities such as leaves and tree roots that follow the mud raw material into the mud raw material mixing barrel 161 are filtered into the collection chamber 1652 of the impurity collection well 165.

[0101] In another specific embodiment of the invention, the mud raw material mixing barrel 161 of the mud raw material mixer 160 is drivably rotated relative to the mud raw material stirring mechanism 163, so that the water in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 and the mud raw material are stirred and mixed in the mud raw material mixing chamber 1611. Optionally, the mud raw material mixing barrel 161 and the mud raw material stirring mechanism 163 of the mud raw material mixer 160 can both be driven to rotate relative to each other to stir and mix the mud raw material and water, thereby producing the mud. In other words, as long as at least one of the mud raw material stirring mechanism 163 and the mud raw material mixing barrel 161 of the mud raw material mixer 160 can rotate relative to each other, the water in the mud raw material mixing chamber 1611 and the mud raw material can be mixed.

[0102] Furthermore, the power mechanism 164 includes a motor assembly 1641 and a motor bracket 1642, wherein the motor bracket 1642 is installed above the mud raw material mixing barrel 161, and the motor assembly 1641 is connected to the first retaining rod 1631 of the mud raw material stirring mechanism 163 in a manner of being installed on the motor bracket 1642.

[0103] In this specific embodiment of the present invention, the mud raw material mixer 160 further includes a limiter 167, wherein the limiter 167 has a limit space 1671 and a plurality of through holes 1672, wherein the limiter 167 is fixed to the lower part of the mud raw material mixing barrel 161, and the limiter 167 is located at the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161, and the through holes 1672 are connected to the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161. The lower end of the first retaining rod 1631 of the mud raw material stirring mechanism 163 is rotatably held in the limit space 1671. The limiter 167 limits the left and right deviation of the mud raw material stirring mechanism 163, which is conducive to preventing the mud raw material mixer 160 from vibrating violently during the stirring process of the mud raw material stirring mechanism 163.

[0104] The slurry raw material mixing barrel 161 of the slurry raw material mixer 160 further has a slurry outlet 1614, wherein the slurry outlet 1614 is located at the bottom of the slurry raw material mixing barrel 161, and the slurry outlet 1614 is connected to the slurry raw material mixing chamber 1611 and the through hole 1672 of the stopper 167. The slurry prepared in the slurry raw material mixing chamber 1611 of the slurry raw material mixing barrel 161 leaves the slurry raw material mixing chamber 1611 through the slurry outlet 1614.

[0105] Reference Figures 5 to 7 The mud raw material mixer 160 further includes a mud raw material control valve 166, the mud raw material filter device 170 has a filter chamber 1701, and the mud raw material storage tank 180 has a mud storage chamber 1801. The mud raw material control valve 166 is arranged at the bottom of the mud raw material mixing barrel 161, and the mud raw material control valve 166 can connect the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 and the filter chamber 1701 of the mud raw material filter device 170. The mud raw material filter device 170 is arranged above the mud raw material storage tank 180 in a manner that the filter chamber 1701 connects the mud storage chamber 1801 of the mud raw material storage tank 180.

[0106] The mud material control valve 166 can be switched between a closed state and a connected state. When the mud material stirring mechanism 163 operates in the mud material mixing chamber 1611 of the mud material mixing barrel 161, the mud material control valve 166 is in the closed state, and the mud material in the mud material mixing chamber 1611 of the mud material mixing barrel 161 cannot enter the filter chamber 1701 of the mud material filtering device 170. After the mud material stirring mechanism 163 mixes the entering mud material evenly, the mud material control valve 166 switches from the closed state to the connected state, and the mud material control valve 166 connects the mud material mixing chamber 1611 of the mud material mixing barrel 161 and the filter chamber 1701 of the mud material filtering device 170. At this time, the mud raw material mixed in the mud raw material mixing chamber 1611 of the mud raw material mixing barrel 161 enters the filtering chamber 1701 of the mud raw material filtering device 170 through the mud raw material control valve 166 .

[0107] The mud entering the filter chamber 1701 of the mud material filter device 170 is filtered in the filter chamber and then enters the mud storage chamber 1801 of the mud material storage tank 180. The filter chamber 1701 of the mud material filter device 170 is provided with a filter net, a filter screen and other elements to prevent the mud material that does not meet the size specifications from entering the mud storage chamber 1801 of the mud material storage tank 180.

[0108] Reference Figure 1 , Figures 8 to 12The stone powder production line 200 includes at least one sand and gravel feeder 210, a sand and gravel crusher 220, at least one sand and gravel conveyor belt 230, a sand and gravel screener 240, a hot air blower 250 and a sand and gravel crusher 260. The sand and gravel feeder 210 weighs and proportions the sand and gravel, and the sand and gravel crusher 220 crushes and refines the weighed sand and gravel. The sand and gravel passing through the sand and gravel crusher 220 are further transported to the sand and gravel screener 240 by the sand and gravel conveyor belt 230, and the sand and gravel screener 240 screens the sand and gravel. After the powdered sand and gravel pass through the sand and gravel screener 240 to obtain sand powder, it is transported to the slurry mixing equipment 300 by the sand and gravel conveyor belt 230 and mixed with the mud raw material prepared by the mud raw material production line 100. The large particles of sand and gravel passing through the sand and gravel screening machine 240 are transported to the sand and gravel crusher 260 by the sand and gravel conveyor belt 230. The sand and gravel crusher 260 crushes the large particles of sand and gravel. The sand powder of qualified size is transported to the slurry mixing equipment 300 under the action of the sand and gravel conveyor belt 230 for preparing the slurry.

[0109] Reference Figure 8 and Fig. 9 The sand and gravel feeder 210 includes a sand and gravel weighing mechanism 211, a sand and gravel conveying mechanism 212 and a support frame 213, wherein the sand and gravel weighing mechanism 211 and the sand and gravel conveying mechanism 212 are arranged above the support frame 213, and the sand and gravel conveying mechanism 212 is located below the sand and gravel weighing mechanism 211, the sand and gravel conveying belt 230 is held at the side of the support frame 213, and the height position of the sand and gravel conveying belt 230 is lower than the height position of the sand and gravel conveying mechanism 212. The sand and gravel weighing mechanism 211 has a sand and gravel weighing space 2111 and a sand and gravel drop opening 2112 connected to the sand and gravel weighing space 2111, and the sand and gravel conveying mechanism 212 is held below the sand and gravel drop opening 2112 of the sand and gravel weighing mechanism 211.

[0110] The sand and gravel outlet 2112 of the sand and gravel weighing mechanism 211 is configured to be switchable between a closed state and an open state. When the sand and gravel outlet 2112 of the sand and gravel weighing mechanism 211 is in the closed state, the sand and gravel are retained in the sand and gravel weighing space 2111 of the sand and gravel weighing mechanism 211 for weighing the weight of the sand and gravel. Accordingly, when the sand and gravel outlet 2112 of the sand and gravel weighing mechanism 211 is in the open state, the sand and gravel retained in the sand and gravel weighing space 2111 of the sand and gravel weighing mechanism 211 is allowed to automatically fall to the sand and gravel conveying mechanism 212 through the sand and gravel outlet 2112, so that the sand and gravel are conveyed by the sand and gravel conveying mechanism 212 toward the direction of the sand and gravel conveyor belt 230. Subsequently, based on gravity, the sand and gravel can automatically fall from the sand and gravel conveying mechanism 212 to the sand and gravel conveyor belt 230.

[0111] Optionally, the sand and gravel conveyor belt 230 is held on one side of the sand and gravel weighing mechanism 211 of the sand and gravel feeder 210, and the sand and gravel weighing mechanism 211 of the sand and gravel feeder 210 pours the weighed raw materials into the sand and gravel conveyor belt 230 by flipping.

[0112] It is worth mentioning that the specific implementation of the sand and gravel feeder 210 is only an example. The sand and gravel feeder 210 only needs to be able to weigh the sand and gravel and transfer the weighed sand and gravel to the sand and gravel conveyor belt 230. In addition, the specific number of the sand and gravel feeder 210 is not limited. The sand and gravel feeder 210 can be implemented as one, two, three or more. The specific number of the sand and gravel feeder 210 can be set according to the specifications of the mud to be prepared. The specific implementation of the sand and gravel feeder 210 shown in the text of the specification and the drawings is only an example and cannot be a limitation on the content and scope of the slurry preparation system 100 of the present invention.

[0113] Reference Figure 1 , Figure 8 and Fig. 9The sand and gravel crusher 220 is located between the sand and gravel conveying mechanism 212 of the sand and gravel feeder 210 and the sand and gravel conveyor belt 230, so that when the sand and gravel conveying mechanism 212 conveys the sand and gravel to the sand and gravel conveyor belt 230, the sand and gravel crusher 220 crushes the sand and gravel to make it fine. The sand and gravel crusher 220 has a sand and gravel crushing space 2201, and the entrance of the sand and gravel crushing space 2201 of the sand and gravel crusher 220 corresponds to the end of the sand and gravel conveying mechanism 212 of the sand and gravel feeder 120, and the outlet of the sand and gravel crushing space 2201 corresponds to the sand and gravel conveyor belt 230, so that the sand and gravel conveying mechanism 212 can transport the sand and gravel to the sand and gravel crushing space 2201 of the sand and gravel crusher 220, so as to allow the sand and gravel to be crushed and refined in the sand and gravel crushing space 2201 of the sand and gravel crusher 220, which is conducive to subsequent uniform mixing, and the crushed and refined sand and gravel can fall to the sand and gravel conveyor belt 230.

[0114] Reference Figure 1 and Fig.10 The sand and gravel screening machine 240 has a screening inlet 2401, a small particle outlet 2402, a screening chamber 2403 and a large particle outlet 2404. A screening screen or a screening net is arranged in the screening chamber 2403 of the sand and gravel screening machine 240 to screen the sand and gravel. The small particle outlet 2402 and the screening inlet 2401 are respectively formed at the upper part and the lower part of the sand and gravel screening machine 240, and are respectively connected to the screening chamber 2403. The large particle outlet 2404 is located at the side of the sand and gravel screening machine 240, and is connected to the screening chamber 2403. Specifically, the sand and gravel crushed by the sand and gravel crusher 220 is transported to the screening inlet 2401 of the sand and gravel screening machine 240 by the sand and gravel conveyor belt 230, and enters the screening chamber 2403 of the sand and gravel screening machine 240 from the screening inlet 2401. After passing through the sand and gravel screening machine 240, the powdered sand and gravel falls into the sand and gravel conveyor belt 230 located below the sand and gravel screening machine 240 from the small particle outlet 2402. The sand and gravel conveyor belt 230 transports the powdered sand and gravel (i.e., the sand powder) to the slurry mixing device 300. The large particles of sand and gravel that cannot pass through the small particle outlet 2402 enter the sand and gravel conveyor belt 230 on one side of the sand and gravel screening machine 240 from the large particle outlet 2404. The sand and gravel conveyor belt 230 connects the sand and gravel screening machine 240 and the crusher 260. The sand and gravel conveyor belt 240 transports the large particles of sand and gravel to the sand and gravel crusher 260 for crushing and refining.

[0115] Continue to refer to the attached Fig.10The hot air blower 250 is connected to the screening chamber 2403 of the sand and gravel screening machine 240. The hot air blower 250 continuously delivers hot air to the screening chamber 2403 of the sand and gravel screening machine 240 to bake the sand and gravel in the screening chamber 2403. After the moisture in the sand and gravel is evaporated, it is easier to be refined.

[0116] Reference Fig.11 The sand and gravel crusher 260 includes a crushing mechanism 261, a screening mechanism 262 and a large particle conveying mechanism 263, wherein the crushing mechanism 261 includes at least one driving motor 2611, at least one crushing mill 2612 and an upper funnel 2613, the screening mechanism 262 includes a lower funnel 2621 and a filtering conveying frame 2622, and the large particle conveying mechanism 263 includes a crushing conveying belt 2631 and a guiding slide 2632.

[0117] The upper hopper 2613 is disposed between the sand and gravel conveyor belt 230 and the pulverizing mill 2612 of the pulverizing mechanism 261, and the pulverizing mill 2612 is drivably connected to the driving motor 2611. The upper hopper 2613 is held above the pulverizing mill 2612, and large particles of sand and gravel fall from the upper hopper 2613 into the pulverizing mill 2612 under the action of the sand and gravel conveyor belt 230, and the driving motor 2611 drives the pulverizing mill 2612 to move, so as to refine the large particles of sand and gravel.

[0118] The lower funnel 2621 of the screening mechanism 262 is held below the pulverizing mill 2612 of the pulverizing mechanism 261. The lower funnel 2621 is connected to the filter conveyor 2622. The lower part of the filter conveyor 2622 is connected to the sand and gravel conveyor belt 230 located below the filter conveyor 2622. The end of the filter conveyor 2622 is connected to the large particle conveying mechanism 263. The sand and gravel passing through the pulverizing mill 2612 falls from the lower funnel 2621 into the filter conveyor 2622, and the filter conveyor 2622 filters the sand and gravel. The powdered sand and gravel of qualified size falls from the filter conveyor 2622 into the sand and gravel conveyor belt 230 below the filter conveyor 2622. The sand and gravel that cannot fall from the filter conveyor 2622 into the sand and gravel conveyor belt 230 has not reached the qualified standard and can only be conveyed to the pulverizing conveyor belt 2631 of the large particle conveying mechanism 263.

[0119] The guide slide 2632 of the large particle conveying mechanism 263 is tiltedly maintained between the guide slide 2632 and the sand and gravel conveying belt 230 connecting the crushing conveying belt 2631 and the crushing mechanism 261, and the guide slide 2632 connects the crushing conveying belt 2631 and the sand and gravel conveying belt 230 of the crushing mechanism 261. Under the action of the crushing conveying belt 2631 of the large particle conveying mechanism 263, the large particles of sand and gravel slide from the guide slide 2632 to the sand and gravel conveying belt 230 connected to the crushing mechanism 261. The large particles of sand and gravel fall from the upper funnel 2613 into the crushing mill 2612 again for further refinement. This cycle is repeated until the sand and gravel are refined to sand powder that meets the preparation standard of the slurry.

[0120] In this specific embodiment of the present invention, the driving motor 2611 and the grinding mill 2612 are respectively implemented as two, wherein one of the driving motor 2611 and the grinding mill 2612 are respectively maintained above the other driving motor 2611 and the other grinding mill 2612, and the sand and gravel passing through the first grinding mill 2612 are refined and fall into the second grinding mill 2612 below for further refinement, so that the size of the sand and gravel can meet the preparation requirements of the slurry.

The sand powder distributing conveyor belt 3121 is driven by the actuating mechanism 243 to move forward or backward, and the sand powder in the sand powder distributing space 3121 can be distributed to different slurry mixers 330. In this way, when one slurry mixer 330 is in the process of mixing the sand powder and mud, the other slurry mixer 330 can be in the loading state, so as to improve the preparation efficiency of the slurry preparation system 1000.

Preferably, after the water stored in the water storage chamber 3201 of the second water tank 320 is poured into the slurry mixer 330, the sand powder distributing mechanism 312 distributes the sand powder into the slurry mixer 330, so as to reduce dust pollution.

[0129] Reference Fig.13 The mud pump 340 is connected to the mud storage chamber 1801 of the mud raw material storage tank 180 of the mud raw material production line 100 and the slurry mixer 330. The mud pump 340 pumps the slurry in the mud storage chamber 1801 into the slurry mixer 330, and after being fully mixed with the sand powder and water, the slurry can be obtained.

The water storage chamber 2501 of the second water tank 320 is connected to the feed chamber 3322 of the feed channel 332. After passing through the feed chamber 3322 of the feed channel 332, the water in the water storage chamber 3201 of the second water tank 320 and the sand powder in the feed chamber 3322 of the feed channel 332 enter the slurry mixing chamber 3311 of the slurry mixing barrel 331 from the lower feed port 3313 of the slurry mixing barrel 331.

[0132] The slurry stirring mechanism 333 is drivably connected to the power device 334, and the slurry stirring mechanism 333 is installed above the slurry mixing barrel 331 in a manner of being held in the slurry mixing chamber 3311. The power device 334 drives the slurry stirring mechanism 333 to rotate in the slurry mixing chamber 3311 to mix the sand powder and the mud entering the slurry mixing chamber 3311.

[0133] The slurry stirring mechanism 333 includes a second holding rod 3331, a second inner spiral 3332, at least two second outer spirals 3333 and a second retaining member 3334, wherein the second inner spiral 3332 extends upward spirally from the lower end of the second holding rod 3331, and the middle part of the second retaining member 3334 is arranged on the second holding rod 3331. The two second outer spirals 3333 extend downward from the two ends of the second retaining member 3334 at intervals to the lower end connected to the second retaining member 3334, and the cross section of the second outer spiral 3333 gradually decreases from top to bottom. The second outer spiral 3333 is located at intervals on the outside of the second inner spiral 3332.

[0134] The upper end of the slurry stirring mechanism 333 is drivably connected to the power device 334, and the power device 334 drives the second retaining rod 3331 to rotate, and drives the second inner spiral 3332 and the second outer spiral 3333 to rotate in the slurry mixing chamber 3311 of the slurry mixing barrel 331. Under the action of the second inner spiral 3332 and the second outer spiral 3333 of the slurry stirring mechanism 333, the water in the middle of the slurry mixing chamber 3311, the sand powder and the mud raw material move upward in a spiral in the middle of the slurry mixing chamber 3311 of the slurry mixing barrel 331, and then fall to the bottom from the periphery of the slurry mixing chamber 3311, and the cycle is repeated so that the sand powder and the mud raw material are evenly mixed to obtain the slurry. Furthermore, the mud and the sand powder collide with the second inner spiral 3332 and the second outer spiral 3333, which can not only stir the mud raw material and the sand powder evenly, but also make the mud raw material and the sand powder refined again.

[0135] Optionally, in another specific embodiment of the present invention, the slurry mixing barrel 331 can be driven to rotate relative to the slurry stirring mechanism 333. Optionally, both the slurry mixing barrel 331 and the slurry stirring mechanism 333 can be driven to rotate.

When the slurry stirring mechanism 333 operates in the slurry mixing chamber 3311, the slurry control valve 335 is in the closed state, and the slurry in the slurry mixing chamber 3311 cannot enter the slurry storage chamber 3501 of the slurry storage tank 350. After the slurry stirring mechanism 333 mixes the sand powder and the mud entering evenly, the slurry control valve 335 switches from the closed state to the connected state, and the slurry control valve 335 connects the slurry mixing chamber 3311 of the slurry mixing barrel 331 and the slurry storage chamber 3501 of the slurry storage tank 350, and the mixed mud in the slurry mixing chamber 3311 enters the slurry storage chamber 3501 through the slurry control valve 335.

[0140] The slurry processing equipment 400 further includes at least one stirring tank 440, wherein the stirring tank 440 is disposed in the finished product storage chamber 4301 of the finished product storage tank 430, and the stirring tank 440 continuously stirs the finished product slurry in the finished product storage chamber 4301 to prevent the slurry from solidifying or unevenly mixing. The stirring tank 440 can also be disposed in the mud storage chamber 1801 of the mud raw material storage tank 180 and the slurry storage chamber 3501 of the slurry storage tank 350 to continuously stir the mud and the slurry.

[0141] It is worth mentioning that the specific numbers of the slurry pump 410, the stirring mill 420 and the stirring kettle 440 are not limited, and the specific numbers disclosed in the drawings of the specification are only for example and cannot be used to limit the content and scope of the slurry preparation system 1000 of the present invention.

[0142] Reference Figures 17 to 19BAccording to another preferred embodiment of the present invention, the slurry raw material production line 100 of the slurry preparation system 1000 will be described in the following description. Figures 17 to 19B The disclosed slurry preparation system 1000 and Figures 1 to 16 The difference between the disclosed slurry preparation system 1000 lies in the slurry raw material mixer 160 of the slurry raw material production line 100. The specific differences will be described in the following description, and the same equipment will not be described again. Figures 17 to 19B The mud raw material mixer 160 of the slurry preparation system 1000 is identified as the mud raw material mixer 160A.

[0143] Specifically, the mud raw material mixer 160A of the mud raw material production line 100 includes a mud raw material mixing barrel 161A, a movable closing member 162A, a mud raw material stirring member 163A, a power mechanism 164A and a closing member driving mechanism 165A. The mud raw material mixing barrel 161A includes a barrel body 1612A and an extension platform 1613A, wherein the barrel body 1612A has a mud raw material mixing chamber 1611A. The extension platform 1613A extends outward from the upper edge of the barrel body 1612A in one piece, that is, the diameter of the extension platform 1613A is greater than the diameter of the barrel body 1612A. The movable closing member 162A has a feeding opening 1621A and a feeding channel 1622A connected to the feeding opening 1621A, and the diameter of the movable closing member 162A is greater than the diameter of the barrel body 1612A.

[0144] The movable sealing member 162A is movably installed above the slurry raw material mixing chamber 1611A in such a manner that the feeding channel 1622A is connected to the slurry raw material mixing chamber 1611A of the barrel body 1612A. The movable sealing member 162A is drivably connected to the sealing member driving mechanism 165A, and the sealing member driving mechanism 165A drives the movable sealing member 162A to move relative to the barrel body 1612A, so that the slurry raw material mixer 160A switches between a decontamination state and a closed state. After the movable sealing member 162A is driven away from the extension platform 1613A of the barrel body 1612A, a debris removal opening 1601A is generated between the sealing member 162A and the extension platform 1613A. At this time, the mud raw material mixer 160A is in the debris removal state, allowing impurities such as leaves and tree roots in the mud raw material mixing chamber 1611A to leave the mud raw material mixing chamber 1611A from the debris removal opening 16101A. When the movable sealing member 162A is driven to move until the lower edge is attached to the extension platform 1613A of the mud raw material mixing barrel 161A, the debris removal opening 1601A is closed. At this time, the mud raw material mixer 160A is in the closed state, and the leaves and tree roots in the mud raw material mixing chamber 1611A cannot leave the mud raw material mixing barrel 161A temporarily.

[0145] The mud raw material stirring member 163A is held in the mud raw material mixing chamber 1611A of the barrel body 1612A in a manner that it is drivably connected to the power mechanism 164A. When the power mechanism 164A drives the mud raw material stirring member 163A to rotate in the mud raw material mixing chamber 1611A, the mud raw material stirring member 163A stirs the mud raw material and water, and can drive impurities such as leaves and roots in the mud raw material mixing chamber 1611A to leave the mud raw material mixing barrel 161A.

[0146] Specifically, the mud raw material stirring mechanism 163A includes a first retaining rod 1631A, a first inner spiral 1632A, at least two first outer spirals 1633A and a first retaining member 1634A, wherein the first inner spiral 1632A spirally extends upward from the lower end of the first retaining rod 1631A, the middle part of the first retaining member 1634A is arranged at the upper end of the first retaining rod 1631A, and each of the first outer spirals 1633A extends downward from the two ends of the first retaining member 1634A at intervals to the lower end connected to the first retaining rod 1631A. The cross section of the first outer spiral 1633A gradually decreases from top to bottom. The first outer spiral 1633A is located at intervals on the outside of the first inner spiral 1632A.

[0147] The upper end of the mud raw material stirring mechanism 163A is drivably connected to the power mechanism 164A, and the power mechanism 164A drives the first retaining rod 1631A to rotate, and drives the first inner spiral 1632A and the first outer spiral 1633A to rotate in the mud raw material mixing chamber 1611A of the mud raw material mixing barrel 161. Under the action of the first inner spiral 1632A and the first outer spiral 1633A of the mud raw material stirring mechanism 163A, the water in the mud raw material mixing chamber 1611A of the mud raw material mixing barrel 161A and the mud raw material move upward in a spiral in the middle of the mud raw material mixing chamber 1611A, and then fall to the bottom along the periphery of the mud raw material mixing chamber 1611A, and the cycle is repeated so that the mud raw materials are evenly mixed. The mud raw material collides with the first inner spiral member 1632A and the first outer spiral member 1633A, which can not only stir the mud raw material evenly but also refine the mud raw material again.

[0148] Impurities such as leaves and tree roots in the mud raw material mixing chamber 1611A that follow the mud raw material into the barrel body 1612A also move from bottom to top under the action of the first inner spiral 1632A and the first outer spiral 1633A. When the leaves and tree roots move close to the extension platform 1612A, under the action of centrifugal force, the leaves and tree roots in the mud raw material mixing chamber 1611A of the barrel body 1612A are thrown to the extension platform 1612A. When the mud raw material mixer 160A is in the impurity removal state, the leaves and tree roots accumulated on the extension platform 1612A leave the mud raw material mixing barrel 161A from the impurity removal opening 16101A.

The closed driving mechanism 165A drives the movable closing member 162A to move up and down so that the mud raw material mixer 160A can switch between the impurity removal state and the closed state.

[0151] Specifically, the closed driving mechanism 165A includes at least one actuating member 1651A and an assembly member 1652A, wherein the assembly member 1652A is fixed to the movable closed member 162A, one end of the actuating member 1651A is fixed to the motor bracket 1642A, and the other end is connected to the assembly member 1652A. The actuating member 1651A telescopically drives the assembly member 1652A and the movable closed member 162A to move up and down, so that the movable closed member 162A moves away from or close to the extension platform 1613A of the mud raw material mixing barrel 161A.

[0152] Preferably, the assembly part 1652A has an assembly hole 16520A, and the first retaining rod 1631A of the mud raw material stirring mechanism 163A is rotatably retained in the assembly hole 1652A of the assembly part 1652A. The two ends of the assembly part 1652A are respectively fixed to the movable closing part 162A, and the actuating member 1651A is implemented as two, and the two actuating members 1651A are symmetrically connected to the two ends of the assembly part 1652A, which is conducive to ensuring that the movable closing part 162A moves smoothly relative to the mud raw material mixing barrel 161A. It is worth mentioning that the specific implementation of the actuating member 1651A is not limited, and the actuating member 1651A can be implemented as a combination of one or more of a hydraulic rod, an electric push rod, a cylinder, or a driving device known to those skilled in the art.

The two conveying slides 1661A are bent and inclined downwardly extending from the position of the extension platform 1613A close to the mud raw material mixing barrel 161A, and a conveying port 16620 is formed between the lower ends of the two conveying slides 1661A. The impurity conveying belt 1662A is located below the conveying port 16620A of the conveying slide 1661A.

[0154] The inner side wall of the conveying chute 1661A close to the mud raw material mixing barrel 161A is located inside the outer edge of the extension platform 1613A, and the upper end of the conveying chute 1661A is located below the extension platform 1613A. When the mud raw material mixer 160A is in the impurity removal state, impurities such as leaves and roots accumulated on the extension platform 1612A are thrown out of the mud raw material mixing barrel 161A from the impurity removal opening 16101A, and the thrown leaves and roots fall into the chute 16610A of the conveying chute 1661A, and the leaves and roots move downward along the extension direction of the chute 16610A, and can subsequently fall from the conveying port 16620 to the impurity conveyor belt 1662A, and the impurity conveyor belt 1662A transports the leaves and roots to the centralized processing area.

[0155] The slurry raw material mixer 160A further includes a slurry discharge mechanism 167A, wherein the slurry discharge mechanism 167A includes a slurry discharge drive member 1671A, a slurry discharge housing 1672A, a spiral transmission member 1673A and a slurry guide member 1674A, wherein the slurry discharge housing 1672A has a conveying chamber 16721A, and the spiral transmission member 1673A has a transmission rod 16731A and a spiral portion 16732A spirally extending from the upper part of the transmission rod 16731A to the lower part. The slurry guide member 1674A has a slurry guide groove 16741A. The barrel body 1612A of the slurry raw material mixing barrel 161A has a slurry discharge port 1614A, wherein the slurry discharge port 1614A is connected to the slurry raw material mixing chamber 1611A of the barrel body 1612A.

[0156] The slurry discharge housing 1672A of the slurry discharge mechanism 167A is disposed on the barrel body 1612A in an upwardly inclined manner in such a manner that the conveying chamber 1672A is connected to the slurry discharge port 1614A, and the spiral transmission member 1673A is rotatably held in the conveying chamber 16721A of the slurry discharge housing 1672A. The spiral transmission member 1673A is drivably connected to the slurry discharge driving member 1671A. The mud guide 1674A is disposed below the slurry discharge housing 1672A in such a manner that the mud guide groove 16741A is connected to the slurry discharge housing 1672A. The mud guide 1674A is located above the slurry raw material filtering device 170, and the mud guide groove 16741A of the mud guide 1674A is connected to the filtering chamber 1701.

[0157] The slurry discharge drive member 1671A drives the spiral transmission member 1673A to rotate in the conveying chamber 16721A of the slurry discharge housing 1672A. After the slurry in the slurry raw material mixing barrel 161A enters the conveying chamber 16721A of the slurry discharge housing 1672A of the slurry discharge mechanism 167A, the slurry moves upward along the extension direction of the spiral portion 1673A of the spiral transmission member 1673A under the action of the spiral transmission member 1673A, and flows from the opening of the slurry discharge housing 1672A to the slurry guide groove 16741A of the slurry guide member 1674A.
