Description

Technical Field

[0001] This utility model relates to the field of mineral screening equipment technology, and in particular to a screen plate separator device based on an electrostatic sieve plate machine. Background Technology

[0002] A sieve plate, also known as a perforated plate, is a metallurgical term. It is characterized by its good wear resistance, long service life, and excellent moisture and abrasion resistance. It is suitable for use in ore washing, screening, grading, slag removal, desliming, and dewatering machinery. An electrostatic separator is a mineral processing device used in electric mineral separation. Its working principle is as follows: When various minerals with different electrical conductivity pass through an electric field, they acquire different charges due to electrostatic induction or the capture of charged ions, exhibiting different characteristics in the electric field. Combined with gravity, this causes them to move along different trajectories. Then, with the help of receiving devices, minerals with different electrical conductivity are separated. The ore after electrostatic separation is then screened by the sieve plate to separate ore particles of different sizes.

[0003] The patent application CN215656331U discloses a high-voltage electric separator, comprising a base, a fixed frame, a screening chamber, a coarse screen plate, a suction screen plate, a receiving plate, and an electrically driven displacement slide. The electrically driven displacement slide is fixedly mounted to one end of the top of the base via a first bolt. The displacement end of the electrically driven displacement slide is a displacement plate, and a mounting vertical plate is welded to one end of the displacement plate. A servo electric cylinder is bolted to one end of the mounting vertical plate. This novel design allows for convenient loading and unloading of the screen plate and receiving plate when needed, eliminating the need for manual loading and unloading, saving time and effort. It also facilitates stable positioning of the screen plate and receiving plate, making it suitable for widespread use. However, the following problems may arise in actual operation:

[0004] 1. Because the screen plate machine uses a motor to drive the screen plate to move back and forth, the minerals move on the screen plate and are screened out into minerals of various specified sizes. However, during the movement, the minerals will remain in the gap between the screen plate and the fixed frame. As a result, after long-term use, the accumulated minerals will affect the movement speed of the screen plate and increase the wear of the screen plate.

[0005] 2. Due to the long-term accumulation of minerals in the gap between the screen plate and the fixed frame, the screen plate may become unable to move after prolonged use, causing the motor to become unable to move and thus become damaged. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a screen plate spacer device based on an electrostatic sieve plate machine, so as to solve the technical problem that mineral debris easily accumulates in the gap between the screen plate and the fixed frame of the current screen plate machine, and long-term accumulation can easily damage the screen plate, causing the screen plate to be unable to move again.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A screen plate spacer device based on an electro-selective screen plate machine includes a screening frame, a screen plate slidably mounted on the top of the screening frame, and a blocking mechanism fixedly mounted on the top of the screen plate by a fixing mechanism.

[0010] The blocking mechanism includes a blocking frame, a sliding groove on the top of the blocking frame, a spring fixedly installed in the inner cavity of the sliding groove, a push block fixedly installed at one end of the spring, and a slot on the top of the push block.

[0011] As an improved technical solution, one side of the push block penetrates through the barrier frame and extends to the outside of the barrier frame, and the outer surface of the push block is slidably connected to the inner surface of the slide groove.

[0012] As an improved technical solution, the barrier mechanism further includes a spacer, the bottom of which is slidably connected to the top of the barrier frame, and a retaining strip is fixedly installed at the bottom of the spacer.

[0013] As an improved technical solution, the outer surface of the card strip is snapped into the inner surface of the card slot, and the outer surface of the spacer is slidably connected to the inner surface of the screening rack.

[0014] As an improved technical solution, the fixing mechanism includes a locking block, the top of which is fixedly connected to the bottom of the barrier frame.

[0015] As an improved technical solution, the fixing mechanism further includes a locking hole, which is opened on the top of the sieve plate, and the inner surface of the locking hole is engaged with the outer surface of the locking block.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model, by adding a barrier design at the edge of the screen plate, and through the cooperation of the screen plate, the barrier frame and the partition strip, the partition strip and the locking strip, the locking groove and the push block, and the push block and the spring, can block the gap between the screen plate and the screening frame, thereby preventing the accumulation of minerals in the gap between the screen plate and the screening frame, which would cause the minerals to jam the screen plate and the screening frame, preventing the screen from sliding on the screening frame.

[0018] 2. This utility model adds a design that allows for the replacement of spacers and quick installation of the spacers onto the screen plate. Through the use of locking blocks and holes in conjunction with the screen plate and the barrier frame, and through the use of locking slots and strips in conjunction with the spacers and the barrier frame, the corresponding spacers can be quickly replaced according to the screen function, thereby improving the diversity of spacers.

[0030] like Figure 1 and Figure 3 As shown in the figure, this embodiment provides a screen plate partition device based on an electro-selection screen plate machine. This screen plate partition device based on an electro-selection screen plate machine includes a screening frame 1, a screen plate 2 is slidably installed on the top of the screening frame 1, and a blocking mechanism 4 is fixedly installed on the top of the screen plate 2 through a fixing mechanism 3.

[0031] The blocking mechanism 4 includes a blocking frame 41, a sliding groove 42 is provided on the top of the blocking frame 41, a spring 43 is fixedly installed in the inner cavity of the sliding groove 42, a push block 44 is fixedly installed on one end of the spring 43, and a slot 45 is provided on the top of the push block 44.

[0032] like Figure 1 and Figure 3 As shown, one side of the push block 44 passes through the barrier frame 41 and extends to the outside of the barrier frame 41, and the outer surface of the push block 44 is slidably connected to the inner surface of the slide groove 42.

[0033] Spring 43 can drive push block 44 to move outward, so that the spacer 46 on push block 44 can stick tightly to screen frame 1, so that no matter where screen plate 2 is on screen frame 1, the gap between screen plate 2 and screen frame 1 can be blocked.

[0034] like Figure 1 and Figure 4 As shown, the barrier mechanism 4 also includes a spacer 46, the bottom of which is slidably connected to the top of the barrier frame 41, and a retaining strip 47 is fixedly installed at the bottom of the spacer 46.

[0035] The spacer 46 is made of rubber and a metal base and has a certain degree of elasticity. At the same time, the spacer 46 is a right-angled triangle, which can guide the falling minerals onto the screen plate 2. Meanwhile, the bottom of the spacer 46 covers the chute 42 to prevent the ore from falling into the chute 42.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the outer surface of the card strip 47 is engaged with the inner surface of the card slot 45, and the outer surface of the spacer strip 46 is slidably connected to the inner surface of the screening rack 1.

[0037] The spacer 46 can be easily replaced through the cooperation between the card strip 47 and the card slot 45.

[0038] like Figure 1 and Figure 3 As shown, the fixing mechanism 3 includes a locking block 31, the top of which is fixedly connected to the bottom of the barrier frame 41.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing mechanism 3 also includes a locking hole 32, which is opened on the top of the screen plate 2, and the inner surface of the locking hole 32 is engaged with the outer surface of the locking block 31.

[0040] A locking hole 32 is made in the sieve plate 2 to fix the barrier frame 41 with the spacer 46 to the sieve plate. At the same time, the barrier mechanism 4 on the sieve plate 2, which is composed of multiple barrier frames 41 and spacer 46, can freely assemble the spacer 46 according to the length of the sieve plate 2.

[0041] In use, the user first places the barrier frame 41 onto the screen plate 2 and inserts the locking block 31 of the barrier frame 41 into the locking hole 32. Then, the user inserts the locking strip 47 of the spacer strip 46 into the locking groove 45. After installing multiple spacer strips 46 and the barrier frame 41 onto the screen plate 2, the screen plate 2 is placed on the screening rack 1. The spring 43 inside the barrier frame 41 pushes the push block 44, and the push block 44 drives the locking strip 47 to move outward through the locking groove 45. The locking strip 47 then drives the spacer strip 46 to move outward. The spacer 46 is placed tightly against the screening frame 1 and moves together with the screen plate 2, so that the minerals on the screen plate 2 will not fall into the gap between the screen plate 2 and the screening frame 1. When the spacer 46 needs to be replaced, the user first removes the screen plate 2 from the screening frame 1, then presses the push block 44 to reset the spring 43, and then the user pulls the spacer 46 to pull the retaining strip 47 on the spacer 46 out of the retaining groove 45 of the push block 44, so that spacers 46 of different shapes can be replaced.

[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
