Description

Technical Field

[0001] The invention relates to the technical field of plate chain bucket elevators, and in particular to a vertical dewatering plate chain elevator. Background Art

[0002] Plate chain elevator is a relatively advanced vertical lifting equipment in China and can be widely used to lift various materials, such as cement, clinker, aggregate, ore, grain, etc.

[0003] Take ore as an example. In the process of ore production and preparation, the ore needs to be soaked or washed to remove impurities on the surface of the ore, resulting in a large water content in the ore, which requires a dehydration step of drainage. At present, most elevators for ore dehydration adopt an inclined design, which occupies a large area, has complex equipment, and is difficult to install. In addition, the elevator is limited by the fixed traditional structure of the hopper. After receiving the ore to be drained, the water can only be drained by gravity. In order to improve the drainage effect, most of them extend the drainage time, resulting in low continuous operation efficiency. At the same time, the drainage holes are easily blocked, affecting the drainage effect.

[0004] Therefore, we consider how to improve the drainage effect of the materials in the hopper and obtain more efficient drainage efficiency; at the same time, we consider vertically lifting the materials to reduce the space occupied by on-site equipment. In view of this, we propose a vertical dewatering plate chain elevator. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies mentioned in the above background technology and provide a vertical dewatering plate chain elevator.

[0014] Preferably, a plurality of vertically arranged toggle plate racks are installed in the drain lifting bin and between the transmission chains, and the upper and lower ends of the toggle plate racks are provided with inclined plates symmetrically arranged on both sides;

[0015] When the hopper is lifted and lowered cyclically along the transmission chain, the extrusion protrusion is squeezed by the inclined plate and then drives the drainage vibration plate to vibrate.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0042] See also Figure 1-11 The present invention describes the above technical solution in detail through the following embodiments:

[0043] A vertical dewatering plate chain elevator, comprising a vertically arranged dewatering lifting bin 1, such as Figure 1 and Figure 2 As shown, in order to feed the ore material and discharge it after draining, the draining lifting bin 1 is provided with a discharge port 101 and a feed port 102, and also includes:

[0044] The vertical lifting part includes a sprocket 3 rotatably mounted at the upper and lower ends of the drain lifting bin 1. In this embodiment, a driving motor 2 for driving the sprocket 3 to rotate is installed on the drain lifting bin 1 to drive the sprocket 3 to rotate; specifically, Figure 3 , Figure 4 In the structure shown, two transmission chains 4 are installed between the upper and lower end sprockets 3, and multiple hoppers 5 are detachably installed between the two transmission chains 4. The walls of the hoppers 5 are provided with drainage holes for draining water during the lifting process. It should be noted that in this embodiment, in order to facilitate disassembly and assembly and keep the installation position of the hopper 5 fixed, the transmission chain 4 includes a plurality of annular chain links 41, and a first connecting plate 42 and a second connecting plate 43 for connecting the chain links 41; four first mounting holes 421 are provided on the first connecting plate 42.

[0045] like Figure 4-Figure 8 In the structure shown in the figure, the hopper 5 in this embodiment includes a silo assembly 52 with mounting side plates 51 at both ends, and the mounting side plates 51 are provided with second mounting holes 511 corresponding to the positions of the first mounting holes 421; bolts are detachably installed between the first mounting holes 421 and the second mounting holes 511, so as to keep the hopper 5 as shown in the figure. Figure 5 and Figure 6 The opening direction shown enables the lifting section to drain, and the opening of the descending section hopper 5 gradually tilts downward, so that the ore material after drainage is poured into the discharge receiving bin 6 detachably installed at the discharge port 101 and discharged.

[0046] Specifically, Figure 8-Figure 11 As shown in the structure, in this embodiment, the silo assembly 52 includes a silo body 521 and a drain vibration plate 522 installed at the bottom of the silo body 521. In order to improve the structural stability when shoveling materials, a supporting cross frame 53 is installed in the silo body 521; it should be noted that, as Fig. 9 , Fig.10 As shown in the structure, in this embodiment, a U-shaped bottom cavity 5211 with vertical sides is creatively provided at the bottom of the warehouse body 521, and the direction maintained during the lifting process is as follows Figure 7 and Fig.10 , the decrease is as Figure 6 The positional relationship shown in the figure, and the bottom surface of the U-shaped bottom cavity 5211 is a downward slope structure, which can maintain a good drainage effect.

[0047] In this embodiment, Figure 5 , Figure 6 As shown in the installation relationship diagram, a uniformly distributed upper and lower arranged toggle plate frame 7 is installed in the drain lifting bin 1 and between the transmission chains 4, and the upper and lower ends of the toggle plate frame 7 are provided with inclined plates 71 symmetrically arranged on both sides; and in this embodiment, the drain vibration plate 522 is connected to the U-shaped bottom cavity 5211 through the first tension spring 524, and a push plate 523 is inserted into the U-shaped bottom cavity 5211 and located below the drain vibration plate 522 through the second tension spring 525 to maintain the tension to prevent the outer end of the push plate 523 from being too long to hinder the lifting; and as Fig.10 As shown in the position relationship, a second protrusion 5231 is provided on the push plate 523, a first protrusion 5221 which is squeezed and matched with the second protrusion 5231 is provided on the inner side of the drainage vibration plate 522, and an extrusion protrusion 5232 is provided at the outer end of the push plate 523 located at the bin body 521; during the lifting and lowering process, the hopper 5 maintains a consistent moving path, which will result in that when the hopper 5 is lifted cyclically along the transmission chain 4, the extrusion protrusion 5232 is squeezed by the inclined plate 71 and then drives the drainage vibration plate 522 to vibrate, and the drainage vibration plate 522 vibrates up and down along the U-shaped bottom cavity 5211, so that the ore material in the hopper can be vibrated and drained, and then the effect is higher and more efficient than natural drainage, and it is also beneficial to reduce the lifting height required for drainage; at the same time, when descending, the hopper 5 pours out the ore material, and the vibration of the drainage vibration plate 522 can also avoid the adhesion and accumulation of the ore material, which is beneficial to maintain the effective space capacity of the hopper 5.

[0048] It should be noted that in this embodiment, the discharge receiving bin 6 is provided with a discharge ramp 61 for receiving the ore material after drainage. When the hopper 5 gradually tilts, the downward slope structure of the bottom surface of the U-shaped bottom cavity 5211 will guide the ore material into the discharge receiving bin 6.

[0049] The vertical dewatering plate chain elevator of this embodiment has the following working principle: the ore material to be drained is introduced through the feed port 102. Figure 5Due to the positional relationship, the transmission chain 4 drives the hopper 5 to rotate counterclockwise during the process, that is, the left side is the movement process of the hopper 5 with the opening facing downward, and the right side is the process of lifting and draining the hopper 5 after filling the material; in the above process, the material scooping at the feed port 102 and the material discharging from the discharging receiving bin 6 are existing common technologies and will not be explained in detail; specifically, when the hopper 5 is lifted after scooping the material, the inclined plate 71 hinders the push plate 523 from pushing inward along the bottom surface of the U-shaped bottom cavity 5211, thereby realizing the lifting of the drainage vibration plate 522. After the inclined plate 71 is offset, under the action of the gravity of the ore material in the hopper and the tension of the first tension spring 524, the drainage vibration plate 522 will reset downward, thereby forming a continuous up and down vibration, which makes the drainage effect better. On the contrary, the vibration of the drainage vibration plate 522 can avoid the problems of clogging of the drainage holes and adhesion of the ore material.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
