Description

Technical Field

[0001] The utility model relates to the technical field of sludge removal devices, in particular to a lifting overflow tank of a sludge removal classifier. Background Technique

[0002] The sludge removal classifier is a device widely used in the ore dressing process, mainly used for sludge removal and classification of pulp. In the sludge removal device such as the overflow tank in the sludge removal classifier, the overflow part realizes the functions of sludge removal and classification. Fine particles (microparticles) are discharged with the overflow of the surface pulp. When the ore feed contains a large amount of mud, the supplementary water can be appropriately increased to reduce the pulp concentration, so as to obtain finer overflow products.

[0003] The existing overflow tank conducts multi-stage diversion, and after that, the concentration of the overflow will be lower than the concentration of the ore feed. The multi-layer structure of the overflow is not convenient for cleaning. For example, in a quartz sand sludge removal device disclosed in the existing patent publication number CN219335103U, it includes a concentration hopper and a sludge removal hopper. The concentration hopper is connected to the sludge removal hopper through a first sand discharge port. The sludge removal hopper includes a second overflow tank annularly arranged on the outer side wall of the top of the sludge removal hopper, a second overflow port arranged on the second overflow tank, and a second sand discharge port arranged at the bottom of the sludge removal hopper; the sludge removal hopper also includes a support frame and a buffer pipe. The above-mentioned sludge removal device can conduct overflow, and sediment and sand are deposited in each tank after overflow, which has the problem of being inconvenient for cleaning. In view of the above problems, a lifting overflow tank of a sludge removal classifier is proposed. Summary of the Utility Model

A first rack 22 is installed on the second overflow ring 20, and an adjusting member driven by the lifting of the first rack 22 is installed on the top plate 13 for adjusting the height of the water spraying and cleaning member.

[0029] In this embodiment, the pulp is input into the first overflow ring 14, that is, inside the tank body 11. Coarse particles (particles with a sedimentation velocity greater than the liquid flow rising velocity) will sink into the tank and be discharged through the sand discharge port at the bottom of the tank body 11. The pulp overflows from the first overflow ring 14 to between the first overflow ring and the second overflow ring 20, and then overflows from the second overflow ring 20 to between the second overflow ring 20 and the third overflow ring 17 for subsequent discharge.

[0030] During overflow, particles will deposit on the top of the tank body 11. The hydraulic telescopic rod 21 adjusts the second overflow ring 20 to rise, and the water spraying and cleaning member descends, so that the top of the tank body 11 can be sprayed and cleaned with water, and the particles can flow out.

[0031] In another embodiment, an output cavity 16 is provided between the third overflow ring 17 and the second overflow ring 20.

The second rack 25 meshes with the driven gear 24. The top end of the second rack 25 is connected to the top end of the mounting rod 27 through a cross bar 26. An adjusting hole is provided on the top plate 13. The support shaft is placed on the shaft body of the adjusting hole and connected to a driving gear 23. The driving gear 23 meshes with the first rack 22;

[0036] When the second overflow ring 20 rises, the first rack 22 rises, driving the driving gear 23 to rotate, the support shaft rotates, driving the driven gear 24 to rotate, thereby driving the second rack 25 to lower, driving the mounting rod 27 to lower through the cross bar 26, so as to drive the water supply pipe 28 to lower when the second overflow ring 20 rises, facilitating cleaning.

[0037] As Figure 3 shown, in another embodiment, guide bars are connected to both sides of the first rack 22. Guide grooves for the sliding of the guide bars are provided on both sides of the adjusting hole; to enable the first rack 22 to perform stable lifting and sliding.

[0038] In another embodiment, a rubber pad is connected to the bottom of the second overflow ring 20, which can improve the sealing performance of the contact between the second overflow ring 20 and the tank body 11.

[0039] As Figure 1 shown, in another embodiment, a support frame 12 is connected to the bottom of the top plate 13; in actual use, according to the installation position of the overflow tank, the tank body 11 can be installed at the target position using the corresponding support structure, and the support frame 12 can be installed at the target position.

[0040] The working principle of the present utility model is: The pulp is input into the first overflow ring 14, that is, inside the tank body 11. Coarse particles will sink into the tank and be discharged through the sand settling opening at the bottom of the tank body 11. The pulp overflows from the first overflow ring 14 to between the first overflow ring and the second overflow ring 20, and then overflows from the second overflow ring 20 to between the second overflow ring 20 and the third overflow ring 17 for subsequent discharge;
