Description

Technical Field

[0001] The utility model relates to the field of calcium carbonate production, in particular to a slurry processing device for calcium carbonate. Background Art

[0002] Calcium carbonate is an inorganic compound and an important building material with a wide range of industrial uses. During its production, slurry is formed due to process problems, and a slurry treatment device is usually required for solid-liquid separation.

[0003] There are many ways to make calcium carbonate. Since the calcium carbonate production process requires the use of water and related compounds for stirring and mixing, slurry will be produced in most calcium carbonate production processes. Due to its chemical properties, it contains a lot of water, so these slurries need to be filtered to achieve solid-liquid separation before subsequent operations can be carried out. The existing calcium carbonate slurry processing device can refer to the Chinese utility model patent with application number: CN202122517452.5, which discloses a calcium carbonate slurry processing device in detail, including a processing box, and support feet are fixedly installed at the four corners of the bottom of the processing box. A rotating ring is rotatably installed on the inner wall of the bottom end of the body corresponding to the inner side position of the inner separation bin, and an annular bevel gear is rotatably installed on the top of the rotating ring. A separation screen is fixedly connected to the top of the annular bevel gear, and an inclined guide plate is fixedly connected to the outer side of the separation screen. A driving motor is fixedly installed on the inner wall of one end of the processing box body, and a transmission pipe is connected to the position of the collecting tank at the bottom end of the processing box body. The beneficial effect of the utility model is that the calcium carbonate slurry on the surface of the separation screen can be centrifuged and filtered. The liquid after centrifugation will pass through the separation screen, thereby facilitating the solid-liquid separation of the calcium carbonate slurry during the treatment process, thereby improving the efficiency of solid-liquid separation during the treatment of the calcium carbonate slurry.

[0004] However, the current filtering method for slurry is to use a normal filter screen to filter, and use gravity or rotating centrifugal force to separate solid and liquid. This filtering method is not only time-consuming, but may also result in insufficient filtration, which will affect the subsequent production process. Utility Model Content

[0014] 1.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] See also Figure 1 - Figure 5 As shown, a slurry processing device for calcium carbonate includes a device body 1, a placement groove 2 is provided at the top of the device body 1, a drainage groove 3 is provided at the bottom of the device body 1, a filter plate 4 is fixedly connected to the bottom of the placement groove 2, and a plurality of filter holes 5 are provided at the top of the filter plate 4, a drainage pipe 6 is fixedly connected to the bottom of one side of the device body 1, and a lifting mechanism is provided on both sides of the top of the placement groove 2, and the lifting mechanism includes two groups of lifting grooves 7, the lifting grooves 7 are provided on both sides of the top of the device body 1, and the two ends of the lifting grooves 7 are rotatably connected to the screw rods 8, and the outer side of the screw rods 8 is threadedly connected to the lifting block 9, an extrusion block 10 is provided inside the placement groove 2, a positioning groove 11 is provided on one side of the lifting block 9, and connecting blocks 12 are fixedly connected to the two sides of the extrusion block 10, and the bottom of the connecting block 12 is fixedly connected to the positioning block 13, and the positioning block 13 is plugged into the positioning groove 11, and a transmission mechanism is provided at the top of the device body 1;

[0025] During operation, the slurry is filtered using a normal filter screen, and solid-liquid separation is performed using gravity or rotating centrifugal force. This filtering method is not only time-consuming, but may also result in insufficient filtration, which affects subsequent production processes. In the present invention, the slurry to be filtered is placed on the filter plate 4 inside the placement tank 2, and then fixed by the extrusion block 10 and the lifting block 9. At this time, turning on the motor 24 and cooperating with the transmission mechanism can drive the two sets of screws 8 to rotate, so that the two sets of lifting blocks 9 will drive the extrusion block 10 to rise and fall, and the extrusion block 10 is lowered to squeeze the slurry on the filter plate 4, and the internal moisture is quickly filtered through pressure, and the moisture passes through the filter hole 5 into the drainage tank 3 for discharge.

[0026] Further, such as Figure 3As shown, the lifting block 9 is inside the lifting slot 7, and the size of the lifting block 9 is adapted to the lifting slot 7;

[0027] During operation, the rotation of the screw 8 will cause the lifting block 9 to have the same tendency to rotate. Since the size of the lifting block 9 is adapted to the lifting slot 7, the tendency of the lifting block 9 to rotate will be hindered by the lifting slot 7. Also, due to the characteristics of the threaded connection between the lifting block 9 and the screw 8, the lifting block 9 can move on the screw 8 as the screw 8 rotates.

[0028] Further, such as Figure 4 As shown, a first through hole 14 is opened on one side of the lifting block 9, and the first through hole 14 passes through the positioning groove 11. A second through hole 15 is opened in the middle of the positioning block 13, and the first through hole 14 is aligned with the second through hole 15. Screws 16 are arranged inside the first through hole 14 and the second through hole 15, and bolts 17 are threadedly connected to the outer side of the screw 16;

[0029] During operation, after the positioning block 13 at the bottom of the connecting block 12 is plugged into the fixing groove at the top of the lifting block 9, the two need to be fixed so that the extrusion block 10 is stable when it descends to extrude the slurry and will not move. When the positioning block 13 is plugged into the positioning groove 11, the first through hole 14 is aligned with the second through hole 15. It is only necessary to insert the screw 16 through the first through hole 14 and the second through hole 15, and then use the bolt 17 to tighten one end of the screw 16, so that the extrusion block 10 can be fixed.

[0030] Further, such as Figure 4 As shown, a handle 18 is provided at the top of the connection block 12, and the handle 18 is fixedly connected to the connection block 12;

[0031] During operation, when the fixing of the positioning block 13 and the positioning groove 11 is released, the squeezing block 10 can be lifted out of the placement groove 2 by the handle 18, so as to process the slurry filtered at the top of the filter plate 4.

[0032] Further, such as Figure 2 As shown, the transmission mechanism includes two groups of first rotating wheels 19, and the bottom ends of the two groups of rotating wheels pass through the top of the device body 1 and are fixedly connected to the tops of the two groups of screw rods 8. The two ends of the front part of the device body 1 are rotatably connected with second rotating wheels 20. The first rotating wheels 19 and the second rotating wheels 20 on the same side of the device body 1 are sleeved with first transmission belts 21 on the outside, and the two groups of second rotating wheels 20 on the front part of the device body 1 are sleeved with second transmission belts 22 on the outside.

[0033] During operation, through the structural design of the transmission mechanism, a first transmission belt 21 is provided on the outer side of the first rotating wheel 19 and the second rotating wheel 20 which are fixedly connected to the screw 8, and a second transmission belt 22 is provided on the outer side of the two sets of second rotating wheels 20, so that any one set of the first rotating wheels 19 or the second rotating wheels 20 can be rotated to drive the two sets of screws 8 to rotate together at the same time, which solves the problem that the stable lifting of the extrusion block 10 requires the two sets of lifting blocks 9 to be lifted and lowered at the same time, so the two sets of screws 8 must rotate at the same time, so it is necessary to install two sets of motors 24 to control the rotation of the screws 8 respectively. Compared with setting one set of motors 24, the setting of two sets of motors 24 increases the production cost.

[0034] Further, such as Figure 1 and Figure 2 As shown, a protective shell 23 is disposed outside the first rotating wheel 19 and the second rotating wheel 20, and the protective shell 23 is fixedly connected to the top of the device body 1, and one end of the protective shell 23 is fixedly connected to a motor 24, and the output end of the motor 24 passes through the protective shell 23 and is fixedly connected to one set of the second rotating wheels 20;

[0035] During operation, the protective shell 23 can protect the transmission device and prevent the staff from colliding with the internal components of the transmission device when they rotate. The protective shell 23 can also prevent the first transmission belt 21 and the second transmission belt 22 from falling off. The motor 24 is the power source for the lifting and lowering of the extrusion block 10.

[0036] Further, such as Figure 3 As shown, an inclined plate 25 is fixedly connected to the bottom end of the drainage trough 3, and the lower side of the inclined plate 25 is close to the drainage pipe 6;

[0037] During operation, the water filtered out by squeezing the slurry will enter the drainage groove 3 through the filter holes 5 on the filter plate 4. Under the action of gravity, the water will flow to the lower end of the inclined plate 25 and then be discharged from the drainage pipe 6.

[0038] Working principle: the slurry to be filtered is placed on the filter plate 4 inside the placement groove 2, and then the positioning block 13 at the bottom of the connecting block 12 is plugged into the fixing groove at the top of the lifting block 9, and the two need to be fixed, so that the extrusion block 10 is stable when it descends to extrude the slurry, and will not move. When the positioning block 13 is plugged into the positioning groove 11, the first through hole 14 and the second through hole 15 are aligned at this time. It is only necessary to penetrate the first through hole 14 and the second through hole 15 with the screw 16, and then use the bolt 17 to tighten one end of the screw 16, so that the extrusion block 10 can be fixed. At this time, turning on the motor 24 and cooperating with the transmission mechanism can drive the two sets of screws 8 to rotate, so that the two sets of lifting blocks 9 will drive the extrusion block 10 to rise and fall, and the lowered extrusion block 10 squeezes the slurry on the filter plate 4, and the internal moisture is quickly filtered through pressure. The moisture passes through the filter hole 5 into the drainage groove 3, and under the action of gravity, the moisture will flow to the lower end of the inclined plate 25, and then be discharged from the drainage pipe 6.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
