Description

Technical Field

[0001] This utility model relates to the field of vacuum filter technology, and more specifically, to an environmentally friendly vacuum filter for iron concentrate production. Background Technology

[0002] In the iron concentrate production process, the slurry containing iron concentrate particles is placed on one side of the filter medium. A vacuum is drawn to create a negative pressure on the other side of the filter medium. Under the action of the pressure difference, the liquid is drawn away through the filter medium, while the iron concentrate is trapped on the surface of the filter medium, thus achieving solid-liquid separation.

[0003] A search revealed an environmentally friendly vacuum filter for iron concentrate production, patent publication number CN222092821U. The specification states that during gear rotation, a rotating rod is synchronously driven to rotate, which in turn drives a rotating plate and a long plate to rotate. The long plate, in turn, drives a soft brush to rotate, and the soft brush simultaneously cleans dust and impurities adhering to the exterior of filter screens one and two, thus ensuring effective ventilation.

[0004] However, in actual use, the dust removed by the soft brush falls directly to the ground. As a result, once the external environment changes, the dust will re-adhere to the outside of the filter screen, thereby increasing the resistance of air passing through the filter screen. This requires the soft brush to be cleaned a second or even multiple times, which will aggravate the wear of the soft brush. This not only increases the cost of use, but also interferes with the normal particle size classification of iron concentrate. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an environmentally friendly vacuum filter for iron concentrate production, which solves the problem that in the prior art, dust will re-adhere to the outside of the filter screen, thereby increasing the resistance of air passing through the filter screen, requiring the soft brush to be cleaned twice or even multiple times, which will aggravate the wear of the soft brush, thus not only increasing the cost of use, but also interfering with the normal particle size classification of iron concentrate.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an environmentally friendly vacuum filter for iron concentrate production, including a housing, with cleaning brushes slidably connected to both the left and right sides of the housing, a push rod fixedly connected to the bottom end of the cleaning brush, placement grooves opened on both the left and right sides inside the cleaning brush, a collection frame slidably connected inside the placement groove, a baffle hinged to the upper side inside the collection frame, and the push rod sliding with the baffle.

[0007] The collection frame has two mounting blocks fixedly connected inside, and each mounting block has a mounting groove inside. One side of the baffle has multiple protruding strips fixedly connected, and the other side of the baffle has two connecting rods hinged to it. The bottom end of each connecting rod is fixedly connected to a connecting piece, and the bottom end of each connecting piece is fixedly connected to an elastic element. The other end of the elastic element is fixedly connected to the mounting groove.

[0008] The inner wall of the placement groove is provided with a limiting groove, and the inner wall of the limiting groove is provided with two slots. The limiting groove is movably connected to a limiting rod, and a sliding plate is fixedly connected between the two limiting rods. An insert block is fixedly connected to the adjacent side of the sliding plate on both the left and right sides.

[0009] The end of the push rod away from the cleaning brush is an arc block structure and is slidably connected to the outside of the protrusion.

[0010] The connecting rod is slidably connected inside the mounting groove, and the connecting piece is slidably connected inside the mounting groove.

[0011] The sliding plate is slidably connected inside the limiting groove, one side of the sliding plate is in contact with the outside of the collecting frame, and the other side of the sliding plate has a snap-on groove.

[0012] The insert block has a conical block structure and is inserted into the slot at the corresponding position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by opening a placement groove on the inner wall of the machine body and sliding a collection frame inside the placement groove, the cleaned dust can be collected. A baffle is used to block the collection frame so that the collected dust will not come out from inside the collection frame, thereby reducing the wear of the soft brush. This not only reduces the cost of use, but also does not affect the normal particle size classification of iron concentrate. Attached Figure Description

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1: Please refer to Figures 1 to 9 This utility model provides a technical solution: an environmentally friendly vacuum filter for iron concentrate production, including a housing 1, which is the outer shell of the vacuum filter and has a filter assembly installed inside. This is prior art and will not be described in detail here. Cleaning brushes 2 are slidably connected to the left and right sides of the housing 1. The cleaning brushes 2 are used to clean the filter screen. A push rod 3 is fixedly connected to the bottom of the cleaning brushes 2. Placement slots 4 are opened on the left and right sides inside the cleaning brushes 2. A collection frame 5 is slidably connected inside the placement slots 4. The placement slots 4 provide installation space for the collection frame 5, and the collection frame 5 has a "T" shaped block structure, which allows the collection frame 5 to slide smoothly. A baffle 6 is hinged to the upper side of the inside of the collection frame 5. The upper side of the baffle 6 can pre-collect dust. The push rod 3 slides with the baffle 6, so that the push rod 3 can push the baffle 6 to rotate downward, thereby allowing the cleaned dust to fall into the inside of the collection frame 5.

[0028] When the cleaning brush 2 is cleaning dust, by pulling the collection box 5 out of the placement slot 4, the dust falls onto the upper side of the baffle 6 as the cleaning brush 2 moves downward. The cleaning brush 2 drives the push rod 3 to move downward, which in turn pushes the baffle 6 to rotate. At this time, the dust on the upper side of the baffle 6 falls into the collection box 5, thus allowing the dust to be collected.

[0029] Example 2: Based on Example 1, in order to improve the dust collection effect, two mounting blocks 8 are fixedly connected inside the collection frame 5. The mounting blocks 8 have mounting grooves 9 inside. Multiple protrusions 7 are fixedly connected to one side of the baffle 6. The end of the push rod 3 away from the cleaning brush 2 is an arc block structure and is slidably connected to the outside of the protrusions 7, so that the push rod 3 can slide conveniently outside the protrusions 7. Two connecting rods 10 are hinged to the other side of the baffle 6. The connecting rods 10 are slidably connected inside the mounting groove 9. The mounting groove 9 limits the connecting rods 10 so that the connecting rods 10 will not deviate when sliding. A connecting piece 12 is fixedly connected to the bottom end of the connecting rod 10. The connecting piece 12 is slidably connected inside the mounting groove 9. The mounting groove 9 limits the connecting piece 12 so that the connecting piece 12 can slide smoothly. An elastic element 13 is fixedly connected to the bottom end of the connecting piece 12. The other end of the elastic element 13 is fixedly connected to the mounting groove 9.

[0030] When the baffle 6 is rotated by the push rod 3 and the push rod 3 contacts the protrusion 7, the baffle 6 pushes the connecting rod 10 downward, which in turn pushes the connecting piece 12 downward, causing the connecting piece 12 to compress the elastic element 13 and deform. As the push rod 3 slides on the baffle 6, when the push rod 3 no longer contacts the protrusion 7, the baffle 6 no longer compresses the connecting rod 10, causing the elastic element 13 to perform a reset movement. At this time, the elastic element 13 pushes the connecting rod 10 upward through the connecting piece 12, causing the baffle 6 to shake, thereby allowing the dust on the upper side of the baffle 6 to quickly enter the interior of the collection frame 5 and not remain on the baffle 6.

[0031] Example 3: Based on Example 2, to facilitate convenient centralized cleaning of dust inside the collection box 5, a limiting groove 18 is provided on the inner wall of the placement groove 4. Two slots 17 are provided on the inner wall of the limiting groove 18. A limiting rod 11 is movably connected inside the limiting groove 18, and the limiting groove 18 limits the limiting rod 11, allowing it to move smoothly. A sliding plate 14 is fixedly connected between the two limiting rods 11. The sliding plate 14 is slidably connected inside the limiting groove 18, providing placement space for the sliding plate 14. With the cooperation of the limiting rod 11, the sliding plate 14 will not detach from the inside of the limiting groove 18. One side of the sliding plate 14 is in contact with the outside of the collection frame 5. The sliding plate 14 plays a limiting role for the collection frame 5, so that the collection frame 5 will not detach directly from the inside of the placement groove 4. The other side of the sliding plate 14 is provided with a snap-fit ​​groove 16, which is used to snap the sliding plate 14. The adjacent sides of the left and right sliding plates 14 are fixedly connected with the insert block 15. The insert block 15 is a conical block structure and is inserted into the corresponding slot 17, thereby limiting the sliding plate 14.

[0032] When the collection frame 5 needs to be disassembled and cleaned, by engaging the latching slot 16, the sliding plate 14 can rotate around the limiting rod 11 as the center, and the insert 15 can disengage from the inside of the slot 17. Then, the sliding plate 14 is pulled outward, so that the limiting rod 11 can slide from one side of the inner wall of the limiting groove 18 to the other side, so that the sliding plate 14 is no longer in contact with the collection frame 5. At this time, the collection frame 5 can be disassembled and cleaned. Conversely, when the collection frame 5 slides into the placement slot 4, the sliding plate 14 is moved in the opposite direction and slid into the inside of the limiting groove 18, so that the insert 15 can be inserted into the inside of the slot 17, thereby limiting the collection frame 5.

[0033] The working process of this utility model is as follows:

[0034] When dust collection is required, the sliding plate 14 rotates around the limiting rod 11 by engaging the engaging slot 16, allowing the insert 15 to disengage from the slot 17. This pulls the sliding plate 14 outwards, causing the limiting rod 11 to slide from one side of the inner wall of the limiting groove 18 to the other. The collection frame 5 is then slid into the placement slot 4, and the sliding plate 14 is moved in the opposite direction, sliding into the limiting groove 18. This allows the insert 15 to be inserted into the slot 17, thus installing the collection frame 5. When the cleaning brush 2 moves downwards, dust falls onto the upper side of the baffle 6, and the cleaning brush 2 drives the push rod 3 downwards, causing the push rod 3 to rotate and continuously contact the push rod 3 and the protrusion 7. The baffle 6 pushes the connecting rod 10 downward, which in turn pushes the connecting piece 12 downward, causing the connecting piece 12 to compress the elastic element 13 and deform. As the push rod 3 slides on the baffle 6, when the push rod 3 no longer contacts the protrusion 7, the baffle 6 no longer compresses the connecting rod 10, allowing the elastic element 13 to reset. At this time, the elastic element 13 pushes the connecting rod 10 upward through the connecting piece 12, causing the baffle 6 to shake. This allows the dust on the upper side of the baffle 6 to quickly enter the interior of the collection frame 5 and not remain on the baffle 6, preventing the collected dust from coming out of the collection frame 5. This reduces the wear of the soft brush, thereby reducing the cost of use and not affecting the normal particle size classification of the iron concentrate.
