Description

Technical Field

[0001] This utility model belongs to the field of filter cake pulping equipment, and in particular relates to a filter cake pulping tank. Background Technology

[0002] Cake pulping is widely used in various fields, such as papermaking, rubber production, and chemical production. In papermaking, cake pulping improves fiber bonding, adjusts drainage, and enhances paper strength and uniformity. In rubber production, it's used to uniformly disperse fillers. In chemical production, it's used for purification operations in organic synthesis. Currently used cake pulping devices have relatively low efficiency, often performing pulping only once in a single tank. The filter cake doesn't mix quickly and evenly with the solution inside the tank, requiring a longer working time to achieve good pulping results. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a filter cake pulping tank.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A filter cake slurry tank includes a tank body. A partition mesh, which is horizontally engaged with the inner wall of the tank body, is located in the middle of the tank body. The internal space of the tank body is divided into an upper cavity and a lower cavity by the partition mesh. A rotating shaft, which penetrates the partition mesh, is vertically arranged inside the tank body. Multiple first stirring blades are fixedly connected to the rotating shaft at the upper cavity and multiple second stirring blades are fixedly connected to the rotating shaft at the lower cavity. Multiple strip-shaped scrapers, which are attached to the partition mesh, are fixedly connected to the rotating shaft at both the upper and lower sides of the partition mesh. A feed inlet is provided on the side wall of the tank body at the upper side of the upper cavity and a discharge outlet is provided at the bottom of the tank body.

[0006] Furthermore, an annular support platform is fixed circumferentially to the inner wall of the tank, and multiple snap-fit ​​blocks are evenly fixed above the support platform on the inner wall of the tank. An annular outer frame is fixed circumferentially to the outer wall of the partition net. Grooves are provided on the outer wall of the outer frame corresponding to the snap-fit ​​blocks. The snap-fit ​​blocks can pass through the grooves and can be staggered with the grooves. The partition net is snapped between the snap-fit ​​blocks and the support platform, and the snap-fit ​​blocks can be fixed to the upper side of the outer frame by screws.

[0007] Furthermore, the tank has an opening at the top, and a cover is fixed to the opening. A motor is fixed to the upper side of the cover at the corresponding pivot point, and the top of the pivot is fixed to the output shaft of the motor.

[0008] Furthermore, the rotating shaft includes a first rotating section and a second rotating section. The top of the first rotating section is fixedly connected to the output shaft of the motor. A square positioning groove is provided at the upper end of the second rotating section. A positioning block that matches the square positioning groove protrudes downward from the bottom of the first rotating section at the corresponding positioning groove. The first rotating section is vertically connected to the upper side of the second rotating section through the cooperation of the positioning block and the square positioning groove. A connecting seat is provided at the lower part of the lower cavity above the discharge port. Multiple connecting rods are evenly fixed to the circumferential side wall of the connecting seat. The other end of the connecting rod is fixedly connected to the inner wall of the tank. The bottom of the second rotating section is connected to the connecting seat through a bearing. Thus, when the motor drives the first rotating section to rotate, the second rotating section can rotate synchronously.

[0009] Furthermore, the partition net has a central hole, and an annular inner frame is fixed to the partition net at the central hole. Circumferentially, annular connecting platforms are fixed to the lower side of the first rotating section and the upper side of the second rotating section. Multiple scraper rods are evenly fixed to the outer wall of each connecting platform, and the two connecting platforms are respectively attached to the upper and lower sides of the inner frame.

[0010] Furthermore, the cross-sectional dimensions of the inner wall of the inner frame are larger than the cross-sectional dimensions of the pivot shaft.

[0011] Furthermore, the side wall of the tank is designed with an inverted conical surface structure at the lower part of the lower cavity, and the discharge port is located at the bottom of the inverted conical surface.

[0012] Furthermore, both sides of the first and second stirring paddles are configured with blade structures.

[0013] Furthermore, multiple fixing blocks are evenly fixed to the outer circumferential wall of the tank, and each fixing block is vertically fixed to a support column at its bottom.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] In use, the filter cake pulping tank of this utility model allows the mixture of filter cake and water to enter the upper chamber through the feed inlet. It undergoes initial pulping by a first stirring paddle on the upper side of the separator screen. After initial pulping, the mixture is filtered through the separator screen and enters the lower chamber, where it undergoes secondary pulping by a second stirring paddle before finally being discharged from the outlet. Simultaneously, a scraper cleans the upper and lower sides of the separator screen to prevent excessive accumulation and clogging. This device effectively improves the filter cake pulping efficiency and allows for easy disassembly and cleaning of the tank's internal structure. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] As shown in the figure, a filter cake slurry tank includes a tank body 1. A partition net 2, which is horizontally engaged with the inner wall of the tank body 1, is located at the center of the tank body 1. The internal space of the tank body 1 is divided into an upper cavity 103 and a lower cavity 104 by the partition net 2. A rotating shaft 3, penetrating the partition net 2, is vertically installed inside the tank body 1. Multiple first stirring paddles 4 are fixed to the rotating shaft 3 at locations corresponding to the upper cavity 103, and multiple second stirring paddles 6 are fixed to the rotating shaft 3 at locations corresponding to the lower cavity 104. Multiple strip-shaped scrapers 502, which are in contact with the partition net 2, are fixed to the rotating shaft 3 at both the upper and lower sides of the partition net 2. A feed inlet 105 is located on the side wall of the tank body 1 at the upper side of the upper cavity 103, and a discharge outlet 106 is located at the bottom of the tank body 1. In this embodiment, both the discharge outlet 106 and the feed inlet 105 are equipped with switching valves. In this embodiment, the mixture of filter cake and water enters the upper cavity 103 through the feed inlet 105, undergoes preliminary slurrying by the first stirring paddle 4 on the upper side of the separator 2, and after preliminary slurrying, the mixture is filtered through the separator 2 and enters the lower cavity 104, where it undergoes secondary slurrying by the second stirring paddle 6, and finally discharged from the discharge outlet 106. Simultaneously, the upper and lower sides of the separator 2 are cleaned by the scraper 502 to prevent excessive buildup and clogging of the separator 2. In this embodiment, the scraper 502 may be equipped with nylon bristles on the side facing the separator 2 for more effective cleaning.

[0028] A ring-shaped support platform 101 is circumferentially fixed to the inner wall of tank 1, and multiple snap-fit ​​blocks 102 are uniformly fixed to the inner wall of tank 1 above the support platform 101. A ring-shaped outer frame 201 is circumferentially fixed to the outer wall of the partition net 2. Grooves 203 are provided on the outer wall of the outer frame 201 corresponding to the snap-fit ​​blocks 102. The snap-fit ​​blocks 102 can pass through the grooves 203 and can be staggered with the grooves 203. The partition net 2 is snapped between the snap-fit ​​blocks 102 and the support platform 101, and the snap-fit ​​blocks 102 can be fixed to the upper side of the outer frame 201 by screws (not shown in the figure). In this embodiment, the snap-fit ​​blocks 102 have through holes, and the outer frame 201 has threaded holes. When the snap-fit ​​blocks 102 pass through the grooves 203 and are staggered with the corresponding grooves 203, the through holes on the snap-fit ​​blocks 102 are aligned with the corresponding threaded holes. At this time, the snap-fit ​​blocks 102 and the outer frame 201 can be fixed by screws. When installing the partition net 2, align the groove 203 with the corresponding snap-fit ​​block 102 and move the partition net 2 downwards until the snap-fit ​​block 102 is fully exposed from the groove 203. At this time, the bottom of the partition net 2 contacts the support platform 101. Then, rotate the partition net 2 horizontally so that the groove 203 and the corresponding snap-fit ​​block 102 are staggered and the through hole on the snap-fit ​​block 102 is aligned with the corresponding threaded hole. Then, fix the snap-fit ​​block 102 and the outer frame 201 with screws. Finally, the partition net 2 is positioned by the snap-fit ​​block 102 and the support platform 101.

[0029] The tank body 1 has an opening at the top, and a cover 9 is fixedly connected to the opening. A motor 10 is fixedly connected to the upper side of the cover 9 at the corresponding position of the rotating shaft 3. The top end of the rotating shaft 3 is fixedly connected to the output shaft of the motor 10. In this embodiment, the top of the tank body 1 has a horizontal connecting edge on the circumference. The edge of the cover 9 is fixedly connected to the connecting edge by multiple bolt and nut pairs (not shown in the figure).

[0030] The rotating shaft 3 includes a first rotating section 301 and a second rotating section 302. The top end of the first rotating section 301 is fixedly connected to the output shaft of the motor 10. The upper end of the second rotating section 302 is provided with a square positioning groove 3021. The bottom of the first rotating section 301 is provided with a positioning block 3011 that matches the square positioning groove 3021. The first rotating section 301 is vertically connected to the upper side of the second rotating section 302 through the cooperation of the positioning block 3011 and the square positioning groove 3021. A connecting seat 7 is provided at the lower part of the lower cavity 104 above the discharge port 106. Multiple connecting rods 8 are evenly fixed on the circumferential side wall of the connecting seat 7. The other end of the connecting rod 8 is fixedly connected to the inner wall of the tank 1. The bottom of the second rotating section 302 is connected to the connecting seat 7 through a bearing. Thus, when the motor 10 drives the first rotating section 301 to rotate, the second rotating section 302 can rotate synchronously. In this embodiment, the positioning block 3011 and the first rotating segment 301 are integrally formed structures.

[0031] The partition net 2 has a central hole, and an annular inner frame 202 is fixedly connected to the central hole. Annular connecting platforms 5 are circumferentially fixed to the lower side of the first rotating section 301 and the upper side of the second rotating section 302. Multiple scraper rods 502 are evenly fixed to the outer wall of each connecting platform 5, and the two connecting platforms 5 are respectively attached to the upper and lower sides of the inner frame 202. In this embodiment, each connecting platform 5 has an annular fixing platform 501 integrally formed with the corresponding connecting platform 5 on the side away from the inner frame 202. Each connecting platform 5 is fixedly connected to the corresponding first rotating section 301 and second rotating section 302 through the fixing platform 501, and the first rotating section 301, second rotating section 302, and corresponding fixing platform 501 are fixed together by screws.

[0032] The inner wall cross-sectional dimension of the inner frame 202 is larger than the cross-sectional dimension of the rotating shaft 3. After the first rotating section 301 is removed, a gap is left between the inner frame 202 and the second rotating section 302 to facilitate the rotation and removal of the partition net 2.

[0033] The side wall of the tank 1 is configured with an inverted conical surface at the lower part of the lower cavity 104, and the discharge port 106 is located at the bottom of the inverted conical surface, which facilitates the collection and discharge of materials. In this embodiment, the end of the connecting rod 8 is fixed to the inverted conical surface.

[0034] Both sides of the first stirring paddle 4 and the second stirring paddle 6 are equipped with blade structures.

[0035] Multiple fixing blocks 11 are evenly fixed to the outer wall of the tank 1. Each fixing block 11 has a vertical support column 12 fixed to its bottom to support the tank 1.

[0036] The working process of this embodiment is as follows:

[0037] The mixture of filter cake and water enters the upper cavity 103 through the feed inlet 105. At the same time, the motor 10 is started to drive the first rotating section 301 and the second rotating section 302 to rotate synchronously, which in turn drives the first stirring paddle 4, the second stirring paddle 6 and the scraper 502 to rotate. The mixture is initially slurried in the upper cavity 103 by the first stirring paddle 4. After the mixture is initially slurried, it is filtered through the separator 2 and enters the lower cavity 104. It is then slurried a second time in the lower cavity 104 by the second stirring paddle 6 and finally discharged from the discharge outlet 106. At the same time, the scraper 502 cleans the upper and lower sides of the separator 2 to prevent the separator 2 from accumulating too much and clogging it.

[0038] When it is necessary to remove the partition net 2, remove the cover 9, and then remove the motor 10, the first rotating section 301, the upper connecting platform 5, and the upper scraper 502 together. Then remove the screws connected to the snap-fit ​​block 102, rotate the partition net 2 so that the groove 203 is aligned with the corresponding snap-fit ​​block 102, and then remove the partition net 2 upwards.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
