Description

Technical Field

[0001] The utility model relates to the technical field of material processing equipment, and specifically, to a tailings double - spiral feeding flocculant adding device for a thickener. Background Technique

[0002] The design usually includes a tailings feeding device and a flocculant adding pipeline. However, this single feeding and adding method has the problem of slow sedimentation rate and is difficult to meet the requirements of high - intensity filling work in mines in a short time.

[0003] To solve this problem, some technical solutions attempt to use multiple flocculant adding devices in order to accelerate the sedimentation rate of tailings slurry. However, these solutions often make it difficult to achieve complete contact between the flocculant and the tailings, resulting in limited improvement in the processing capacity per unit area. Other technical solutions use spiral pipelines to extend the mixing time of the tailings and the flocculant and improve the tailings sedimentation effect. However, this method often causes waste of layout space and increases the equipment cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tailings double - spiral feeding flocculant adding device for a thickener to solve the problem that using multiple flocculant adding devices often makes it difficult to achieve complete contact between the flocculant and the tailings, resulting in limited improvement in the processing capacity per unit area as proposed in the above - mentioned background technique.

[0005] To achieve the above - mentioned purpose, the utility model provides a tailings double - spiral feeding flocculant adding device for a thickener, which includes a tailings feeding device, a flocculant adding device, and a tailings - flocculant reaction device. The tailings - flocculant reaction device is of a two - helix structure, and the two - helix structures are closely arranged. An outlet is provided at the end of the inner side of each of the two - helix structures. The tailings feeding device includes two tailings feeding pipes, and the two tailings feeding pipes are horizontally connected to the end of the outer side of the helix structure. The connection between the tailings feeding pipe and the end of the outer side of the helix structure is the feeding port. The flocculant adding device includes two flocculant feeding pipes, and the flocculant feeding pipes are vertically intersecting. 4 - 6 spraying heads are arranged at the bottom of each flocculant feeding pipe.

[0006] Preferably, the wall plate of the helix structure is a spiral side plate, and the bottom plate is a bottom plate. A material groove is arranged between the two spiral side plates and the bottom plate. The two material grooves are separated by the spiral side plates and are relatively independently arranged.

[0007] Preferably, the two - helix structures rotate in the same direction and are closely nested with each other. The material groove has a slope from the outer end to the inner end so that the tailings can automatically flow towards the mixing port at a certain slope.

[0008] Preferably, the bottom of the discharge port is connected to a mixing pipe through a connection port. The mixing pipe is arranged inside the thickener. A discharge port is provided at the bottom of the thickener, and the bottom end of the mixing pipe is connected to the discharge port.

[0009] Preferably, the diameter of the tailings feed pipe is between 1 / 3 and 2 / 3 of the width of the trough and is equal to the diameter of the feed port.

[0010] Preferably, the flocculant feed pipe supplies flocculant to the spray head.

[0011] Preferably, the spray head is located above the trough and is evenly distributed directly above the spiral side panel so that the spray head can evenly spray the flocculant into the troughs of the two spirals.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the tailings double-spiral feeding flocculant adding device for the thickener, the double-spiral feeding method enables the tailings slurry to flow rapidly in the trough and naturally converge towards the mixing port due to the slope design of the trough, effectively accelerating the sedimentation speed of the tailings and meeting the requirements of high-intensity filling work in mines in a short time. The flocculant is evenly sprayed into the troughs of the two spirals through the spray head and is fully mixed with the tailings slurry, significantly increasing the contact area and contact time between the tailings and the flocculant, thereby improving the mixing effect and flocculation efficiency. Compared with the traditional single feeding and adding methods, the double-spiral structure and the design of multiple flocculant spray heads of the present utility model significantly improve the processing capacity per unit area, enabling the thickener to process tailings more efficiently.

[0014] The tightly nested design of the double spirals not only simplifies the device structure but also effectively utilizes the space, avoiding the waste of layout space caused by the traditional spiral pipeline method. By optimizing the feeding and flocculant adding methods, the present utility model not only improves the processing efficiency but also reduces the equipment cost and operating cost, having significant economic benefits.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a tailings double - spiral feeding and flocculant adding device for a thickener, as Figures 1 - 3 shown, which includes a tailings feeding device, a flocculant adding device, and a tailings - flocculant reaction device. The tailings - flocculant reaction device is in the structure of two spirals, and the two spirals are closely attached. At the end of the inner side of each of the two spiral structures, there is a discharge port 101. The tailings feeding device includes two tailings feed pipes 201, and the two tailings feed pipes 201 are horizontally connected to the end of the outer side of the spiral structure. The connection between the tailings feed pipe 201 and the end of the outer side of the spiral structure is the feed port 202. The flocculant adding device includes two flocculant feed pipes 301, and the flocculant feed pipes 301 are vertically intersecting. At the bottom of each flocculant feed pipe 301, 4 - 6 spray heads 302 are arranged. The device uses a double - spiral structure as the reaction area for tailings and flocculant. This design enables the tailings and flocculant to be fully mixed and reacted in the two spirals, thereby improving the sedimentation speed and effect of the tailings. The tailings feeding device uses two tailings feed pipes, which are respectively connected to the outer ends of the two spirals. This design enables the tailings to enter the two spirals evenly, avoiding problems such as uneven feeding or blockage. The flocculant adding device, through two flocculant feed pipes, arranges 4 - 6 spray heads at the bottom of each pipe. This design enables the flocculant to be evenly sprayed onto the tailings, further improving the mixing effect and sedimentation rate. Due to the adoption of a double - spiral structure and an optimized feeding and flocculant adding method, the device of the present invention has a higher processing capacity compared with traditional thickeners and can meet the requirements of high - intensity filling work in mines in a short time. The two spiral structures are closely attached, making the structure of the whole device more compact, effectively utilizing the space, and reducing the floor area and cost of the equipment.

[0022] In this embodiment, the wall panel of the spiral structure is the spiral side panel 102, the bottom plate is the bottom panel 103, a material groove 104 is arranged between the two spiral side panels 102 and the bottom panel 103, and the two material grooves 104 are separated by the spiral side panels 102 and are relatively independently arranged.

[0023] Specifically, the two spiral structures rotate in the same direction and are tightly nested with each other. The material groove 104 has a slope decline from the outer end to the inner end, so that the tailings can automatically flow towards the mixing port at a certain slope.

[0024] Furthermore, the bottom of the discharge port 101 is connected to the mixing pipe 400 through the connection port 105. The mixing pipe 400 is arranged inside the thickener 100, and a blanking port 500 is arranged at the bottom of the thickener 100. The bottom end of the mixing pipe 400 is connected to the blanking port 500.

[0025] Furthermore, the diameter of the tailings feed pipe 201 is between 1 / 3 and 2 / 3 of the width of the material groove 104 and is equal to the diameter of the feed port 202.

[0026] Furthermore, the flocculant feed pipe 301 supplies the flocculant to the spray head 302.

[0027] Furthermore, the spray head 302 is located above the material groove 104 and is evenly distributed directly above the spiral side panel 102, so that the spray head 302 can evenly spray the flocculant into the material grooves 104 of the two spirals.

[0028] When the tailings double-spiral feeding flocculant adding device for the thickener of the present utility model is in use, first, the tailings enter the device through the two tailings feed pipes 201, and these two feed pipes are respectively connected to the feed ports 202 at the outer ends of the two spirals. The diameter of the tailings feed pipe 201 is designed to be between 1 / 3 and 2 / 3 of the width of the material groove 104 to ensure that the tailings can smoothly and evenly enter the material grooves 104 of the two spirals. The flocculant enters the device through the two flocculant feed pipes 301, and 4-6 spray heads 302 are arranged at the bottom of each feed pipe. The spray head 302 is located above the material groove 104 and is evenly distributed directly above the spiral side panel 102 to ensure that the flocculant can be evenly sprayed onto the tailings. The two spiral structures rotate in the same direction and are tightly nested with each other. The material groove 104 has a slope decline from the outer end to the inner end. The tailings automatically flow towards the mixing port in the material groove 104 due to the slope and are fully mixed and reacted with the evenly sprayed flocculant at the same time. This design improves the contact area and contact time between the tailings and the flocculant, thereby enhancing the mixing effect and flocculation efficiency.

[0029] The mixed tailings slurry is discharged through the discharge port 101 at one end inside the two screws. The bottom of the discharge port 101 is connected to the mixing pipe 400 through a pipeline, and the mixing pipe 400 is arranged inside the thickener 100. After the mixed slurry enters the thickener 100, it further settles inside the thickener and is finally discharged through the discharge opening 500 at the bottom of the thickener.
