Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Please refer to Figures 1 to 8 , Figure 1 A schematic diagram of the structure of a laboratory slurry stirring and feeding device provided in a specific embodiment of the utility model; Figure 2 for Figure 1 A top view of Figure 3 for Figure 1 Cross-sectional view of the middle BB; Figure 4 for Figure 1 A partial enlarged view of the middle A; Figure 5 for Figure 3 A partial enlarged view of point C in the middle; Figure 6 It is a schematic diagram of the structure of the tank; Figure 7 It is a structural schematic diagram of the tank cover; Figure 8 Schematic diagram of the connection between the tank cover and the tank body.

[0043] The laboratory slurry stirring and feeding device provided by the utility model comprises a rotating disk 8, a rotating cylinder 9 connected to the rotating disk 8 for driving the rotating disk 8 to rotate circumferentially, a tank body 6 connected to the rotating disk 8, a tank cover covering the opening of the tank body 6, and a lifting mechanism connected to the tank cover for driving the tank cover to move up and down. An inclined block 17 is provided at the upper end of the outer wall of the tank body 6, and a buckle 5 is connected to the tank cover. When the tank cover and the tank body 6 are connected, when the tank cover covers the opening of the tank body 6, the rotating cylinder 9 drives the tank body 6 to rotate by driving the rotating disk 8, and the inclined block 17 is snapped into the buckle 5.

[0044] In the above structure, the laboratory slurry stirring and feeding device includes a rotating disk 8, a rotating cylinder 9, a tank body 6, a tank cover and a lifting mechanism.

[0045] The disk surface of the rotating disk 8 is along the horizontal plane, and the rotating disk 8 can rotate around its axis. The rotating cylinder 9 is connected to the rotating disk 8, and the rotating cylinder 9 is used to drive the rotating disk 8 to rotate in a circle around the vertical axis.

[0046] The tank body 6 is connected to the rotating disk 8. Specifically, the tank body 6 can be fixed to the rotating disk 8 by bolts, and the connection is detachable, and the connection and disassembly are convenient. The opening of the tank body 6 is located on its upper end surface, and the tank cover is located above the tank body 6, and the axis direction of the tank cover coincides with the tank body 6. The tank cover is covered at the opening of the tank body 6 to cover the tank body 6. The lifting mechanism is connected to the tank cover to drive the tank cover to rise and fall, so that the tank cover covers the opening of the tank body 6 or is away from the opening of the tank body 6.

[0047] The upper end of the outer wall of the tank body 6 is provided with a plurality of inclined blocks 17, which are distributed along the circumferential direction. Specifically, the inclined blocks 17 can be connected to the tank body 6 by welding, and the connection strength is relatively high.

When the inclined block 17 and the buckle 5 are clamped with each other, the buckle 5 limits the circumferential rotation of the inclined block 17, and the can body 6 cannot continue to rotate, so that the rotating disk 8 stops rotating and the rotating cylinder 9 stops moving, thereby realizing the connection and automatic locking of the can cover and the can body 6.

[0051] It should be noted that the specific rotation angle of the rotating disk 8 is determined by the angle at which the inclined block 17 is engaged with the buckle 5 . As long as the inclined block 17 is not engaged with the buckle 5 , the rotating disk 8 can rotate until the buckle 5 blocks and limits the inclined block 17 .

[0052] In a preferred embodiment, the inclined blocks 17 are evenly distributed along the circumferential direction of the tank body 6, the locking points of the tank body 6 and the tank cover are evenly distributed, and the forces in the circumferential direction are balanced, thereby preventing the tank cover and the tank body 6 from being subjected to too concentrated forces, thereby preventing the tank cover from tilting up at a position with less force.

[0053] The laboratory slurry stirring and feeding device provided by the utility model adopts a rotating cylinder 9 to drive the tank body 6 to rotate, and utilizes the inclined block 17 to cooperate with the buckle 5 to lock the tank cover, thereby realizing automatic locking and opening of the tank cover, being easy to operate and reducing the labor intensity of personnel; the inclined block 17 and the buckle 5 are locked firmly and have good sealing performance.

[0054] On the basis of the above-mentioned specific embodiments, a bayonet is provided on the side of the buckle 5 , the bayonet is along the circumferential direction of the can cover, and a chamfer is provided on the bottom surface of the bayonet that cooperates with the inclined block 17 .

[0055] In a specific embodiment, the bayonet is opened on the side of the buckle 5, and the bayonet is along the circumferential direction of the tank cover. The shape of the bayonet is the same as the shape of the inclined block 17, and the size of the bayonet can be equal to the size of the inclined block 17. After the inclined block 17 is inserted into the bayonet, the two are locked tightly.

[0056] The upper surface of the bottom surface of the bayonet is connected with the vertical surface by chamfering, and the upper surface edge of the bottom surface of the bayonet is chamfered, and the angle is equal to that of the inclined block. The lower surface of the inclined block 17 is an inclined surface, that is, the matching surface with the bayonet is an inclined surface.

[0057] On the basis of the above-mentioned specific embodiments, the matching surface between the inclined block 17 and the bayonet is an inclined surface.

[0058] In a specific embodiment, when the bevel block 17 is inserted into the bayonet, the lower bevel of the bevel block 17 contacts and locks with the chamfer. When locked, the screwing length is surface contact, the contact area is large, the force area is increased, and it is easy to lock and unscrew without getting stuck.

[0059] Based on the above-mentioned specific embodiments, the matching surfaces of the inclined block 17 and the bayonet have the same inclination.

[0060] In a specific embodiment, the lower surface of the inclined block 17 is an inclined surface, and the lower surface of the bayonet is also an inclined surface, and the inclinations of the two are the same. The lower surface of the inclined block 17 is in close contact with the lower surface of the bayonet, and the contact area is large. The two inclined surfaces slide relative to each other and are pressed and locked against each other.

[0061] On the basis of the above-mentioned specific embodiments, the inclined surface length of the inclined block 17 is greater than the inclined surface length of the bayonet.

[0062] In a specific embodiment, the size of the inclined block 17 is slightly larger than the size of the bayonet, and the inclined blocks 17 are locked with each other before they completely enter the bayonet, leaving a wear margin for the bayonet and the inclined block 17.

[0063] Based on the above specific embodiments, the thickness of the inclined block 17 is equal to the width of the bayonet.

[0064] In actual applications, the inclined block 17 and the bayonet are tightly fitted, not only in the height and length directions, but also in the thickness direction of the inclined block 17, that is, along the radius of the tank body 6. The inclined block 17 and the bayonet are also tightly fitted. Specifically, the thickness of the inclined block 17 and the width of the bayonet can be equal, or they can be loosely fitted, for example, there is a 1mm gap. The two are tightly fitted to reduce shaking and ensure the tightness of the fit between the tank cover and the tank body 6.

[0065] On the basis of the above-mentioned specific embodiments, the buckle 5 is detachably connected to the tank cover, the buckle 5 is L-shaped, and the vertical plate is connected to the outer wall of the tank cover, the lower horizontal plate is located below the bottom surface of the tank cover, and there is a gap between the lower horizontal plate and the bottom surface of the tank cover, and the buckle is specifically the gap, and the upper edge of the side of the lower horizontal plate is provided with a chamfer equal to the angle of the inclined block.

[0066] In practical applications, the buckle 5 is a detachable buckle, including but not limited to the buckle 5 being connected to the tank body 6 by screws, so as to facilitate the adjustment and maintenance of each clamping point.

[0067] The buckle 5 is L-shaped, including a vertical plate and a lower horizontal plate, the lower horizontal plate is connected to the lower end surface of the vertical plate, and one side of the vertical plate and the lower horizontal plate are flush. Preferably, the buckle 5 is formed by bending, the connection is smooth, and the processing is convenient; of course, it can also be formed by welding.

[0068] The vertical plate is in contact with the outer wall of the tank cover. Preferably, the vertical plate and the tank cover have the same curvature, and the vertical plate and the tank cover fit tightly. Furthermore, the inner side of the vertical plate and the outer wall of the tank cover are provided with matching positioning grooves and positioning ribs, which can not only locate the connection position of the vertical plate and the tank cover, but also make the connection between the vertical plate and the tank cover more convenient; it can also prevent the vertical plate and the tank cover from relative rotation and up and down displacement, and improve the accuracy of the connection position. The vertical plate and the tank cover can be connected by screws, the tank cover has a threaded hole, the vertical plate has a through hole, and the screws are connected to the through hole and the threaded hole.

[0069] The lower transverse plate is located below the bottom surface of the tank cover. The length of the lower transverse plate is less than the wall thickness of the tank cover. The lower transverse plate faces the side of the tank cover. The end of the lower transverse plate does not contact the outer wall of the tank body 6 and does not interfere with the rotation of the tank body 6.

[0070] There is a gap between the lower transverse plate and the bottom surface of the tank cover, and the bayonet is specifically the gap. The tank body 6 rotates toward the side close to the corresponding card block, and the inclined block 17 enters from one side of the gap. The inclined surface of the lower side of the inclined block 17 is pressed on the side of the lower transverse plate. The upper edge of the side of the lower transverse plate is provided with a chamfer. The inclined surface of the inclined block 17 is in contact with the chamfered surface, which increases the force-bearing area of ​​the inclined block 17 and the card block, is not easy to crush the edge of the locking surface of the lower transverse plate, and extends the service life of the buckle 5.

[0071] Based on the above-mentioned specific embodiments, the lifting mechanism includes a lifting slide 1 slidably connected to the track, a lifting arm 2 connected to the lifting slide 1, a guide hole is provided on the lifting arm 2, and a guide rod 16 is connected to the tank cover. The guide rod 16 is along the vertical direction, and its lower end is inserted into the guide hole from top to bottom.

[0072] In practical applications, the lifting mechanism includes a track, a lifting slide 1 and a lifting arm 2. The track is along the vertical direction, the lifting slide 1 is connected to the track, and the motor drives the lifting slide 1 to move up and down along the track.

[0073] Preferably, the lifting slide 1 is a lifting screw slide, a screw is provided on the track, the lifting screw slide cooperates with the screw, and the lifting screw slide is limited by the track, so the movement is more stable.

[0074] One end of the lifting arm 2 is connected to the lifting slide 1, and the lifting arm 2 and the lifting slide 1 are fixedly connected and lifted synchronously. The lifting arm 2 is provided with at least two guide holes.

[0075] The lower surface of the flange of the tank cover is connected with a guide rod 16, which matches the number, position, shape and size of the guide holes. For example, four guide holes are set at 90° intervals, and the guide holes are circular holes. The corresponding number of guide rods 16 is four, which are distributed at 90° intervals, and the cross section of the guide rod 16 is circular. The axial directions of the guide rod 16 and the guide hole are along the vertical direction, and the lower end of the guide rod 16 is inserted into the guide hole from top to bottom. The guide hole limits the circumferential position of the guide rod 16, and prevents the tank cover from rotating when the tank body 6 is locked.

[0076] Furthermore, the guide hole and the guide rod 16 are clearance-matched, and the guide rod 16 can slide in the guide hole, that is, the tank cover and the lifting arm 2 are in a floating connection. When the tank cover is lowered, the guide rod 16 of the tank cover is inserted into the guide hole of the lifting arm 2, and the upper surface of the lifting arm 2 contacts the lower surface of the tank cover. The lifting arm 2 lifts the tank cover down and covers the tank cover at the opening of the tank body 6. The position of the tank cover is fixed by multiple sets of guide rods and cannot rotate circumferentially, but the up and down directions are not fixed. When the tank cover is lowered into place, the lifting arm 2 needs to be lowered by a set distance, such as to a position 10 mm below the lifting contact surface, avoiding the locking position of the tank cover to prevent axial interference between the tank cover and the lifting mechanism when locked. After the rotating cylinder 9 pushes back the tank body 6 to unlock it, the lifting slide 1 can be lifted to lift the tank cover.

[0077] Based on the above specific embodiments, a circle of grooves is provided on the lower end surface of the tank cover, and a rubber pad 15 is connected in the groove. When the tank cover and the tank body 6 are connected, the upper edge of the tank body 6 is inserted into the groove, and the upper end surface abuts against the rubber pad 15.

[0078] In actual application, the width of the groove is slightly larger than the wall thickness of the tank body 6. When the tank cover and the tank body 6 are connected, the upper edge of the tank body 6 is inserted into the groove. The groove limits the connection position of the tank body 6 to prevent the tank cover and the tank body 6 from being misaligned, and to prevent the tank body 6 and the tank cover from shifting in the radial direction, thereby ensuring that the tank cover and the tank body 6 fit tightly.

[0079] The depth of the groove is greater than the thickness of the rubber pad 15 . When the can cover and the can body 6 are connected, the upper end surface of the upper edge of the can body 6 abuts against the rubber pad 15 , and the rubber pad 15 is pressed to achieve sealing.

[0080] Based on the above specific embodiments, it also includes:

[0081] An air inlet valve 13 provided on the tank cover and connected to the compressed air;

[0082] A discharge valve 3 provided at the lower part of the tank body 6;

[0083] A pressure sensor 11 for detecting the internal pressure of the tank 6;

[0084] An alarm device connected to the pressure sensor 11 is used to send out an alarm to remind the operator to check whether the discharge valve 3 is blocked when the internal pressure of the tank body 6 is greater than a first preset value.

[0085] In practical applications, an air inlet valve 13 is provided on the tank cover, and the air inlet valve 13 is connected to compressed air, and the compressed air enters the tank body 6 through the air inlet valve 13. A discharge valve 3 is provided at the lower part of the tank body 6, and the material is discharged into the lower process through the discharge valve 3.

[0086] The laboratory slurry stirring and feeding device operates according to the following steps:

[0087] Open the tank cover to add powder, lower the tank cover to lock it, add water and stir it, then introduce compressed air through the air inlet valve 13, and open the discharge valve 3 to automatically discharge the material into the next process.

[0088] In the above embodiment, compressed air is introduced after automatic stirring, and the material is introduced into the lower equipment, which is suitable for stirring minerals or chemical raw materials with high viscosity, realizes automatic production, and reduces the labor intensity of personnel.

[0089] Furthermore, a pressure sensor 11 is provided on the inner side of the tank cover, and the pressure sensor 11 is used to detect the internal pressure of the tank body 6. When the discharge valve 3 discharges materials normally, the internal pressure of the tank body 6 is constant and does not change much. When the discharge valve 3 discharges materials abnormally, the internal pressure of the tank body 6 increases, indicating that the discharge valve 3 is blocked.

[0090] The alarm is connected to the pressure sensor 11. When the internal pressure of the tank body 6 is greater than the first preset value, which is greater than the normal discharge pressure value in the tank body 6, the alarm sounds an alarm to remind the operator to promptly check whether the discharge valve 3 is blocked so as to clean the discharge valve 3 as soon as possible to ensure smooth discharge.

[0091] It should be noted that the alarm can be a flashing LED light or an announcer. As long as it can send out a warning signal, it is within the protection scope of the present utility model.

[0092] Based on the above specific embodiments, it also includes:

[0093] An exhaust valve 14 provided on the tank cover;

[0094] A controller connected to the pressure sensor 11, the exhaust valve 14 and the intake valve 13, for closing the intake valve 13 and / or opening the exhaust valve 14 when the internal pressure of the tank body 6 is greater than a second preset value, the second preset value being greater than the first preset value.

[0095] In actual application, an exhaust valve 14 is provided on the tank cover, and the gas in the tank body 6 can be discharged from the exhaust valve 14. The controller is connected to the exhaust valve 14 and the air inlet valve 13 of the pressure sensor 11, and the pressure sensor 11 sends the internal pressure value of the tank body 6 to the controller in real time. The controller compares the internal pressure value of the tank body 6 with the second preset value based on the received internal pressure value of the tank body 6. The second preset value is the limit pressure value in the tank body 6, and the second preset value is greater than the first preset value. When the internal pressure value of the tank body 6 is greater than the second preset value, it means that the pressure in the tank body 6 has reached the limit state, and it is necessary to close the air inlet valve 13 and / or open the exhaust valve 14 in time to relieve the pressure of the tank body 6, so as to ensure that the internal pressure of the tank body 6 is within the tolerable range of the tank body 6 and the tank cover, and ensure the safety of the experiment.

[0096] Based on the above specific embodiments, it also includes:

[0097] A water inlet valve 12 provided on the tank cover;

[0098] After adding powder into the tank body 6, the controller is used to control the exhaust valve 14 to open so that the internal pressure of the tank body 6 is less than the third preset value, and the third preset value is less than the first preset value. The controller is also used to control the water inlet valve 12 to open to add a set amount of water.

[0099] In actual application, after adding powder into the tank body 6, the controller controls the exhaust valve 14 to open to exhaust the air inside the tank body 6 as much as possible, such as reducing the internal pressure of the tank body 6 to less than a third preset value, which is smaller and less than the first preset value.

[0100] The tank cover is provided with a water inlet valve 12, and the controller is connected to the water inlet valve 12. The controller controls the water inlet valve 12 to open and add a set amount of water, which is proportional to the weight of the powder. The stirring shaft 7 in the tank body 6 rotates under the drive of the stirring motor 4 to stir the powder and water, and discharge the material after stirring.

[0101] In the above embodiment, after the powder is added, the air in the tank body 6 is exhausted, and compressed air is introduced into the tank body 6 during discharge, so that the material can be discharged quickly, thereby reducing the amount of compressed air introduced.
