[0046] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0047] Reference Figures 1-7For the first embodiment of the utility model, propose a kind of anti-precipitation stirring device, comprising: base body 1;Rotary shaft 2 is rotationally arranged relative to base body 1, and is sleeved on base body 1;Suctioning element 8 is swinged and arranged on base body 1, and the swing axis of suctioning element 8 is perpendicular to the axis of rotary shaft 2, and suctioning element 8 is used to spray ore pulp to filter disc after swinging.

[0048] In the embodiment, the working process of the stirring device is as follows: when the equipment starts to operate, the ore pulp conveying system and other related systems of the pressure filter are started synchronously, at the same time, the driving device (such as an external small motor connected with the rotary shaft 2) drives the rotary shaft 2 to start rotating, and the rotary shaft 2 rotates stably under the support of the base body 1. Specifically, the rotary shaft 2 is sleeved on the base body 1, and the base body 1 serves as a stable foundation of the entire structure, so that the rotary shaft 2 and the subsequent components can operate without shaking, displacement or other adverse conditions, and occupy less space. The stirring device is arranged between adjacent filter discs, and disturbs the ore pulp flowing between the filter discs to solve the problem of uneven ore pulp at the bottom of the ore pulp tank.

[0049] The two suctioning elements 8 spray ore pulp to the direction of the filter disc 20, break the static precipitation area that may be formed at the bottom of the ore pulp tank, and promote the continuous flow and circulation of the ore pulp, especially at the corner or position close to the inner wall at the bottom of the ore pulp tank. The structure sprays ore pulp in this way, which can further increase the area of adsorbed ore pulp to optimize the filtration efficiency.

[0050] Specifically, due to the position of the stirring device, two groups of symmetrical suctioning elements 8 are arranged to spray ore pulp to different filter discs, the suctioning arm 801 drives the suctioning plate 802 to swing, the two swing axes have a larger swing angle, and the swing power can be additionally provided with an eccentric wheel or cam structure on the rotary shaft 2. When the rotary shaft 2 rotates, the eccentric wheel or cam rotates, the circular motion of the eccentric wheel or cam is converted into the reciprocating push-pull motion of the connecting rod, and then the suctioning arm 801 is driven to periodically swing on the base body 1 around the swing axis, for example, when the protruding part of the eccentric wheel gradually approaches the connecting point of the connecting rod, the connecting rod drives the suctioning arm 801 to swing outward, and when the protruding part of the eccentric wheel moves away, the connecting rod drives the suctioning arm 801 to swing back under the action of the auxiliary return force such as spring or gravity, or an external small motor.

[0051] Further, the two suctioning elements 8 are arranged between the rotary shaft 2, and the suctioning element 8 comprises: the suctioning arm 801 is swinged and arranged on the base body 1;The suctioning plate 802 is swinged and arranged on the end of the suctioning arm 801 away from the base body 1.

[0052] In this embodiment, when the stirring device is started, the pulp lifting arm will swing around its connection point with the base, and the pulp lifting plate swing is arranged at one end of the pulp lifting arm. With the swinging of the pulp lifting arm and the impact of the material on the pulp lifting plate, the pulp lifting plate will also swing at the end of the pulp lifting arm. In this process, the swinging of the pulp lifting arm and the pulp lifting plate will continuously cut into the slurry, lifting the slurry that is deposited at the bottom or unevenly distributed to the side.

[0053] The double swinging structure design allows the pulp lifting member to flexibly adjust its posture according to the different viscosity, flowability and other states of the material. For example, when encountering more viscous slurry, the pulp lifting arm and the pulp lifting plate can change the angle and position by swinging, better cutting into the slurry for pulp lifting, effectively avoiding the problem of unable to normally lift the slurry or insufficient pulp lifting due to excessive resistance of the slurry.

[0054] Further, the pulp lifting arm 801 swing axis is parallel to the pulp lifting plate 802 swing axis, and the pulp lifting arm 801 swing axis is perpendicular to the shaft 2 axis. It also includes: a stop block 9 is arranged on one end of the pulp lifting arm 801 close to the pulp lifting plate 802, located on one side of the pulp lifting plate 802, and the stop block 9 is arranged along the length direction of the pulp lifting arm 801. The pulp lifting plate 802 abuts or cancels the abutment of the stop block 9 after swinging, and the stop block 9 is used to limit the swing angle of the pulp lifting plate 802.

[0055] In this embodiment, due to the two sets of swing points, in order to prevent the swing reset from disturbing the slurry caused by any swing of the pulp lifting plate 802, a stop block 9 is integrally formed on the pulp lifting arm 801 at the back of the pulp lifting plate 802. The stop block 9 stops and limits the rotating position of the pulp lifting plate 802. When the pulp lifting arm 801 resets, the back of the pulp lifting plate 802 is stressed at this time, and starts to rotate under the resistance of the slurry to achieve the effect of reducing the moving resistance in the slurry. In order to improve the blocking effect, it is arranged along the length direction of the pulp lifting arm 801.

[0056] In the continuous slurry processing process, stable and consistent slurry lifting action is one of the key factors to ensure the uniformity of the slurry and the stability of the filtering effect. Since the stop block 9 fixes the swing angle of the pulp lifting plate 802, the trajectory and intensity of the pulp lifting plate 802 each time are basically the same, so that the throwing and mixing of the slurry are highly consistent. The process of lifting and conveying the slurry from the bottom of the slurry tank to the filter disc 20 is standardized, the characteristics of the slurry entering the filter disc 20 fluctuate very little, which helps to stabilize the formation speed, thickness and quality of the filter cake, and ensures the stability of the filter liquid output quality.

[0057] Further, the ring body 10 is arranged on the rotating shaft 2, the ring body 10 is coaxially arranged with the rotating shaft 2, the transmission block 11 is movably arranged relative to the rotating shaft 2 and is sleeved on the rotating shaft 2, the transmission block 11 moves to be close to or away from the ring body 10, the connecting rod 12 is hingedly connected with the pulp lifting arm 801 and the transmission block 11 at two ends, respectively, wherein, after the ring body 10 rotates with the rotating shaft 2, the transmission block 11 is driven to move, for driving the pulp lifting arm 801 to swing.

[0058] Further, the transmission block 11 is located above the ring body 10, the ring body 10 has a first protrusion 1001 at the top, the transmission block 11 has a second protrusion 1101 at the bottom, after the ring body 10 rotates with the rotating shaft 2, the first protrusion 1001 lifts or cancels the lifting of the second protrusion 1101.

[0059] Further, the elastic member 13 is sleeved on the rotating shaft 2 and is located above the transmission block 11, one end of the elastic member 13 abuts against the base body 1, the other end abuts against the transmission block 11, and the elastic member 13 provides a force for the transmission block 11 to be close to the ring body 10.

[0060] In the embodiment, when the stirring device starts to work, with the rotation of the rotating shaft 2, the ring body 10 sleeved thereon rotates synchronously, the first protrusion 1001 at the top of the ring body 10 also performs a circular motion, in the initial state, under the elastic force of the elastic member 13, the transmission block 11 is pressed to the direction close to the ring body 10, the second protrusion 1101 at the bottom of the transmission block 11 is in a contactable state with the first protrusion 1001 on the ring body 10, when the ring body 10 rotates to the first protrusion 1001 contacts and lifts the second protrusion 1101, the transmission block 11 moves upward against the elastic force of the elastic member 13, since the connecting rod 12 is hingedly connected with the pulp lifting arm 801 and the transmission block 11 at two ends, respectively, the upward movement of the transmission block 11 drives the pulp lifting arm 801 through the connecting rod 12, so that the pulp lifting arm 801 swings outward around the swing shaft 5 thereof on the base body 1, at this time, the pulp lifting plate 802 at the end of the pulp lifting arm 801 away from the base body 1 lifts the ore pulp, and the ore pulp is thrown and scattered in the direction of the filter disc 20, conversely, the first protrusion 1001 gradually moves away from the second protrusion 1101, under the elastic force recovery of the elastic member 13, the transmission block 11 falls downward to the initial position, the pulp lifting arm 801 is pulled to swing reversely through the connecting rod 12, and is reset, ready for the next ore pulp lifting action.

[0061] The structure directly utilizes the rotating power of the rotating shaft 2 to drive the pulp lifting arm 801 to swing by skillfully arranging the ring body 10 and the matched transmission block 11 and other components on the rotating shaft 2, without the need of additionally increasing a complex independent driving motor or a complex transmission device to control the pulp lifting action, so that the overall structure of the equipment is greatly simplified, and the utilization of the first protrusion 1001 and the second protrusion 1101 can absorb part of the impact force generated by the collision, so as to avoid the abrasion of components due to frequent rigid impact.

[0062] Further, the sleeve pipe 14 is arranged to rotate relative to the rotating shaft 2 and is sleeved on the rotating shaft 2; and the stirring blade disc 16 is arranged at the bottom of the sleeve pipe 14 and is coaxially arranged with the sleeve pipe 14.

[0063] Further, the stirring blade disc 16 is arranged at the bottom of the sleeve pipe 14, and in working, the stirring blade disc 16 rotates with the sleeve pipe 14 and can produce horizontal stirring action on the ore pulp at the bottom of the ore pulp tank, so that the ore pulp at the bottom forms circumferential flow, and the ore pulp is prevented from being deposited at the bottom.

[0064] Further, the rotating shaft 2 is a low-speed rotating shaft, and the application further comprises a driving member 15 arranged on the rotating shaft 2, which drives the sleeve pipe 14 to rotate.

[0065] In the embodiment, in order to further improve the stirring effect, the rotation centrifugal force is used to generate a moving pushing force to the two side filter discs, and after the ore pulp is pushed and contacted on the filter disc unit, a certain wave crest is formed, so that the area of the filter disc unit for adsorbing the ore pulp is increased relative to the stationary ore pulp tank, so as to improve the filtering efficiency of the ore pulp.

[0066] Specifically, the stirring blade disc 16 is arranged at the bottom of the sleeve pipe 14 and rotates with the sleeve pipe 14 in working, and can produce horizontal stirring action on the ore pulp at the bottom of the ore pulp tank, so that the ore pulp at the bottom forms circumferential flow, and the ore pulp is prevented from being deposited at the bottom.
