Description

Technical Field

[0001] The utility model belongs to the field of dust removal fans, and in particular relates to a dust removal fan for ore testing. Background Art

[0002] During the test of ore, dust is generated, and a fan is often used to blow the ore for testing to achieve the effect of dust removal. For example, the utility model patent with the authorization announcement number CN217748565U proposes a dust removal fan for ore testing, including a fan, the front side of the fan is connected to a telescopic hose, the end of the telescopic hose away from the fan is connected to an air collecting hood, the bottom of the fan is fixedly connected to a mounting mechanism, and the left side of the mounting mechanism is fixedly connected to a storage mechanism. The utility model cooperates with the fan, the telescopic hose, the air collecting hood, the mounting mechanism and the storage mechanism.

[0003] Most of the existing dust removal fans are installed by bolts, which is inconvenient to disassemble, and after the dust is blown or sucked away, dust is easily generated on site. Therefore, it is necessary to improve it. Summary of the invention

[0004] The utility model aims to provide a dust removal fan for ore testing, which solves the problem that most of the existing dust removal fans are installed by bolts and are inconvenient to disassemble, and at the same time solves the problem that dust is easily generated on site after the dust is blown away or sucked away.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a dust removal fan for mineral testing, including a mounting base and an exhaust pump, a base is arranged at the bottom of the exhaust pump, the base is in contact with the exhaust pump, the input end of the exhaust pump is connected to a dust collecting cover by a thread, a dust collecting mechanism is arranged on the inner side of the dust collecting cover, a bidirectional screw is installed inside the mounting base through a bearing, a moving block is connected to the outer side of the threaded portion of the bidirectional screw by a thread, a locking pin is fixedly connected to the upper end of the moving block, the locking pin passes through the mounting base and is slidably connected to the mounting base, and the locking pin is slidably connected to the base.

[0006] The principle of the utility model is that when in use, first place the base at the bottom of the vacuum pump on the mounting base, then turn the bidirectional screw by turning the knob, then the two moving blocks move toward each other by the relative threaded motion between the bidirectional screw, then the locking pins on the moving blocks also move synchronously, then the locking pins are stuck into the corresponding grooves on the base and lock the base, thus completing the installation of the vacuum pump, and similarly, the vacuum pump can be disassembled by turning the knob in reverse;

[0007] When the vacuum pump is working, the plug can be sucked up and separated from the cone tube, and then the ore powder on the ore testing table will be intercepted by the filter and then collected uniformly, making it less likely for dust to appear next to the ore testing table.

[0008] The beneficial effect of the utility model is that a dust collecting hood is installed at the input end of the vacuum pump, and then a dust collecting mechanism is arranged on the inner side of the dust collecting hood. When the vacuum pump is working, the plug can be sucked up and the plug can be separated from the cone tube. Then, the ore powder on the ore testing table will be intercepted by the filter screen and then collected uniformly, so that dust is not easy to appear near the ore testing table.

[0009] Two moving blocks with bidirectional screws for controlling the position are arranged in the mounting base, and a locking pin is arranged on the top of each moving block. After the locking pin moves laterally with the moving block, it can be laterally inserted into the base of the vacuum pump. In this way, the disassembly and assembly of the vacuum pump can be completed by simply controlling the clutch of the locking pin and the base. Compared with the previous bolt installation method, it is more convenient and quicker.

[0010] Furthermore, one end of the bidirectional screw rod located outside the mounting base is fixedly connected with a knob, and the knob is made of plastic. The setting of the knob facilitates the rotation of the bidirectional screw rod.

[0011] Furthermore, a ball bearing is arranged at the bottom of the moving block, and the ball bearing is slidably connected to the inner surface of the mounting base. The relative friction between the moving block and the mounting base can be reduced by the arrangement of the ball bearing.

[0012] Furthermore, a guide rod is fixedly connected to the inner bottom of the mounting base, and the guide rod penetrates the moving block and is slidably connected to the moving block. The setting of the guide rod has a guiding effect on the moving block.

[0013] Furthermore, the dust collecting mechanism includes a cone tube fixedly connected to the inner wall of the dust collecting hood, a slag discharge port is provided at the bottom of the cone tube, a plug is slidably connected to the inner side of the upper opening of the cone tube, a filter is fixedly connected to the outer side of the plug, and the filter is slidably connected to the inner side of the dust collecting hood, a sleeve is fixedly connected to the upper end of the filter, a slide bar is slidably connected to the inner side of the sleeve, the top of the slide bar is fixedly connected to the inner surface of the dust collecting hood, and a spring is provided on the inner side of the sleeve. The dust collecting mechanism is provided to facilitate the unified collection of ore powder.

[0014] Furthermore, the bottom of the cone tube is in contact with a retaining ring, the upper end of the retaining ring is fixedly connected with a positioning bead, and the positioning bead is clamped with the cone tube. By setting the retaining ring, the slag discharge port can be blocked.

[0015] Further, one end of the spring is fixedly connected to the slide bar, and the other end of the spring is fixedly connected to the inner surface of the sleeve. Through the setting of the spring, the elastic force can be applied to the filter screen and the plug. BRIEF DESCRIPTION OF THE DRAWINGS
