Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore dressing, especially relates to a wet screening device for ore dressing test materials. BACKGROUND

[0002] Grinding is an important part of ore dressing technology, and the main purpose is to dissociate minerals in the ore and grind the ore to a suitable size for separation. Laboratory research on ore dressing test often involves wet screening of test materials, especially in the grinding fineness test link. Wet screening is carried out in a basin, and the water in the basin is replaced every few minutes until the water in the basin is no longer turbid, so as to find out the curve relationship between grinding time and grinding fineness and determine the optimal grinding fineness. Currently, manual screening is used, which not only increases the labor intensity of workers, but also has low screening efficiency and cannot guarantee the accuracy of screening data.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN202010484700.8 discloses a wet screening device for fine particle material. The patent vibrates up and down through the standard screen to avoid the enrichment of fine particle material in a certain area of the standard screen, and quickly and accurately screens the fine particle material. Although the above-mentioned patent has the effect of automatic screening, it is troublesome to replace the screen mesh. When coarse screening is needed after fine material screening is completed, a set of screen mesh needs to be removed and another set of screen mesh needs to be replaced, which is troublesome and cannot quickly switch the fine screen mesh to the coarse screen mesh. Moreover, the current screening device is not convenient for quick replacement of the water tank. Since the water tank needs to be replaced in time after screening, adding water after waterproofing will result in long replacement time and affect work efficiency. Therefore, it is necessary to design a wet screening device for ore dressing test materials. UTILITY MODEL CONTENTS

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-4 As shown, a wet screening device for mineral processing test materials includes a base plate 1 and a screen plate 2. The upper surface of the screen plate 2 is provided with large screen holes 3 and small screen holes 4, which are arranged at intervals. A baffle 5 is rotatably connected to the middle of the upper surface of the screen plate 2. A through hole is provided on one side of the upper surface of the baffle 5, and a limit rod 6 is slidably connected inside the through hole.

[0026] In this embodiment, a tension spring 7 is fixedly connected to the top end of the limiting rod 6, and the bottom end of the tension spring 7 is fixedly connected to the baffle 5.

[0027] In practical use, the baffle 5 can rotate on the screen plate 2. First, the large screen hole 3 is blocked by rotating the baffle 5. Then, the material is placed on the screen plate 2 for screening. Small particles in the material are screened out through the small screen hole 4, achieving the effect of screening small-sized particles. When it is necessary to screen large particles, the baffle 5 can be rotated to the top of the small screen hole 4 to block it and expose the large screen hole 3, which has the effect of quickly switching screen holes.

[0028] In this embodiment, a first limiting groove 8 is provided on the side of the upper surface of the sieve plate 2 near the large sieve hole 3, and a second limiting groove 9 is provided on the side of the upper surface of the sieve plate 2 near the small sieve hole 4.

[0029] In practical use, when the limiting rod 6 is pulled upward, the tension spring 7 is compressed and deformed. The spring 7's rebound characteristic keeps the limiting rod 6 under downward force. Then, by rotating the baffle 5, the large sieve hole 3 or the small sieve hole 4 is blocked. After the limiting rod 6 is released, the tension spring 7 drives the limiting rod 6 to move downward into the first limiting groove 8 or the second limiting groove 9, so that the baffle 5 can be fixed on the large sieve hole 3 and the small sieve hole 4.

[0030] In this embodiment, electric telescopic rods 10 are installed on both sides of the upper surface of the base plate 1, and the output ends of the two electric telescopic rods 10 are fixedly connected to a horizontal plate 11. A spring assembly 12 is fixedly connected to the lower surface of the horizontal plate 11.

[0031] In practical use, the electric telescopic rod 10 has the function of raising and lowering, which facilitates the adjustment of the horizontal plate 11 up and down, and the spring assembly 12 makes the support plate 13 and the screen plate 2 have a shaking effect.

[0032] In this embodiment, a support plate 13 is fixedly connected to the bottom end of the spring assembly 12, and a vibration motor 14 is installed on one side of the support plate 13.

[0033] In practical use, the vibration motor 14 can generate a vibration effect after starting, so that the support plate 13 and the screen plate 2 have a vibration effect to facilitate screening.

[0034] In this embodiment, a rotating shaft is rotatably connected to one side of the support plate 13, and a locking hole is provided on the outer surface of the support plate 13 near the rotating shaft. The rotating shaft is fixedly connected to the screen plate 2, and a locking post 15 is threaded to one end of the rotating shaft.

[0035] In practical use, after rotating the locking pin 15 and moving it into the locking hole, the rotating shaft and the screen plate 2 can be quickly fixed. When the screen plate 2 needs to be cleaned, first move the screen plate 2 upward out of the water surface, release the locking pin 15, and then use the rotating shaft to make the screen plate 2 flip over, which is convenient for cleaning and maintenance.

[0036] In this embodiment, a support box 16 is fixedly connected to the upper surface of the base plate 1, and a slide rod 17 is slidably connected to one side of the support box 16. There are two slide rods 17, and one end of the slide rod 17 is fixedly connected to the first water tank 18.

[0037] In practical use, the slide bar 17 can slide on the support box 16, which facilitates the movement of the first water tank 18 and the second water tank 19 below the screen plate 2.

[0038] In this embodiment, the end of the slide bar 17 away from the first water tank 18 is fixedly connected to the second water tank 19. The lower surfaces of the first water tank 18 and the second water tank 19 are both provided with sliding wheels 20, and the bottom ends of the first water tank 18 and the second water tank 19 are both connected with drain valves 21.

[0039] In practical use, the sliding wheel 20 provides support for the first water tank 18 and the second water tank 19, facilitating sliding, while the drain valve 21 facilitates drainage by opening and closing.

[0040] Working principle: During use, water is first added to the first water tank 18 and the second water tank 19. The slide bar 17 slides on the support box 16, pushing the first water tank 18 to below the screen plate 2. After the electric telescopic rod 10 retracts, it lowers the horizontal plate 11, causing the screen plate 2 to contact the water surface of the first water tank 18. Then, the material is placed on the screen plate 2 for sieving. The vibration motor 14 is started to drive the screen plate 2 to sieve. Small particles in the material are sieved through the small screen holes 4, achieving the effect of sieving small-sized particles. For larger particles... When granulating, the baffle 5 can be rotated above the small sieve hole 4 to block it. At this time, the material passes through the large sieve hole 3, which can separate the larger particles in the material. It has the function of quickly switching sieve holes. After the material is sieved, it falls into the first water tank 18. When cleaning is required, the slide bar 17 can be moved to one side to pull out the first water tank 18. At the same time, the second water tank 19 moves to the bottom of the sieve plate 2. At this time, the first water tank 18 is drained and cleaned. Screening can continue while draining, which greatly increases the work efficiency.

[0041] Example 2

[0042] like Figure 5 As shown, the distinguishing feature of this embodiment from that of embodiment 1 is that a lighting lamp 22 is fixedly connected to one side of the back of the horizontal plate 11.

[0043] In practical use, the use of lighting lamp 22 can produce light at night or when there is insufficient light, making it easier for staff to see the surrounding environment of the screening device.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
