Description

Technical Field

[0001] This utility model relates to the field of chromite sand production technology, specifically a stone crusher for chromite sand production. Background Technology

[0002] A stone crusher is a crushing machine that uses the high-speed impact of hammers to perform medium and fine crushing of materials. The hammers are hinged to a high-speed rotating rotor, and grate bars are installed at the bottom of the machine to control the discharge particle size. The material fed into the crusher is first crushed by the impact of the high-speed hammers, simultaneously gaining kinetic energy and flying at high speed towards the crushing plates on the inner wall of the machine casing for further crushing. Material smaller than the grate gaps is discharged from the machine, while material larger than the grate gaps is subjected to further impact and grinding by the hammers on the grate bars until it is smaller than the grate gaps and is then discharged.

[0003] Existing stone crushers generate excessive dust during the crushing process, causing environmental pollution and wasting resources. At the same time, the ore produced by existing stone crushers is of inconsistent quality and cannot be used directly. Therefore, we need to propose a stone crusher for chromite ore production.

[0014] 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.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a crusher for chromite sand production, including a base 1 and a crusher body 2. The crusher body 2 is installed above the base. A main drive motor 3 is installed on one side of the crusher body 2, and a dust removal component for crushing and removing dust is installed on the other side of the crusher body 2. The dust removal component includes an air pump 6, which is installed above the base 1 and located away from the main drive motor 3. A filter 5 is provided at the air inlet end of the air pump 6. The filter 5 is installed above the base 1 and its discharge port is connected to the cavity of the base 1. The discharge port of the filter 5 is connected to the feed end of the sand funnel 8. An exhaust shell 7 is provided at the exhaust end of the air pump, which is installed above the base 1 and located away from the filter 5. A housing 4 is provided at the air inlet end of the dust removal component. The housing 4 is located above the base 1 and is connected to the side of the crusher body 2 closest to the dust removal component. A filter screen 21 is provided at the opening of the housing 4. The filter screen 21 can filter 0-1mm dust. By activating the air pump 6, the air inlet of the air pump 6 can collect the dust generated during the stone crushing process through the housing 4 and the filter 5. By setting the filter screen 21, the size of the extracted material can be precisely limited to prevent the filter 5 from having difficulty filtering. By setting the sand funnel 8, the dust can be collected and filtered in conjunction with the filter 5. By setting the exhaust housing 7, the filtered gas can be discharged.

[0016] Furthermore, a sand funnel 8 is installed inside the cavity of the base 1. The inlet end of the sand funnel 8 is correspondingly set with the dust removal component, and a gravity flap valve for controlling waste discharge is installed at the discharge end of the sand funnel 8. The gravity flap valve includes a rotating shaft 12, which is rotatably connected to the bottom of the sand funnel 8. A connecting rod 10 and a valve plate 11 are respectively connected to both sides of the rotating shaft 12. A counterweight 9 is connected to one side of the connecting rod 10 away from the rotating shaft 12. When the dust inside the sand funnel 8 accumulates to a set weight, the gravity of the dust acts on the valve plate 11, which can rotate the valve plate 11 around the rotating shaft 12 to open it. By setting the counterweight 9, after the dust inside the sand funnel 8 is discharged, the counterweight 9 can drive the valve plate 11 around the rotating shaft 12 to close it through the connecting rod 10.

[0017] Furthermore, a screening component for screening mineral sand is installed inside the cavity of the base 1. The screening component is spaced apart from the inner wall of the cavity to form a predetermined gap. The screening component includes a screening machine housing 13. A groove is provided on the top of the screening machine housing 13. A screen 17 is installed inside the groove. The screen 17 is directly below the discharge end of the crusher body 2. The screen 17 can screen out 0-2mm mineral sand. A partition 15 is connected to one side of the screen 17 away from the discharge end of the screening component. The distance between the partition 15 and the counterweight 9 near it is 5-6cm. A collection tray 16 is installed between the screen 17 and the lower surface of the screening machine groove. The collection tray 16 is directly below the discharge end of the sand funnel 8. By setting a predetermined gap, the outer shell 13 of the screening machine can be prevented from colliding with the surface of the cavity. By setting a screen 17, it can cooperate with the sand at the discharge end of the crusher body 2 for screening. By setting a collection plate 16, the dust discharged from the sand funnel 8 and the screened ore sand can be collected. By setting a baffle 15, the sand at the discharge end of the crusher body 2 can be precisely limited from entering the screen 17, preventing unscreened ore sand from directly entering the collection plate 16.

[0018] The screening assembly also includes two sets of vibrating motors 14, which are symmetrically arranged on the side of the screening machine housing 13 away from the discharge port of the screening assembly. A first discharge port 19 and a second discharge port 20 are respectively installed on the side of the screen 17 and the collection tray 16, located at the discharge end of the screening assembly. Both the first discharge port 19 and the second discharge port 20 are 1-2 cm lower than the upper surface of the screen 17 and the collection tray 16. By activating the two sets of vibrating motors 14, the vibrating ends of the motors drive the screen 17 and the collection tray 16 to move up and down reciprocally through the screening machine housing 13. This reciprocating movement screens and linearly moves the ore on the surface of the screen 17, and also linearly moves the ore on the surface of the collection tray 16. This linear movement allows the ore to enter the first discharge port 19 and the second discharge port 20. Since both discharge ports are 1-2 cm lower than the upper surface of the screen 17 and the collection tray 16, blockages during ore discharge are prevented.

[0019] In addition, four sets of telescopic rods 18 are installed between the screening machine housing 13 and the lower surface of the base 1 cavity. The movable ends of the four sets of telescopic rods 18 are respectively connected to the four corners of the lower surface of the screening machine housing 13, and the fixed ends of the four sets of telescopic rods 18 are connected to the lower surface of the base 1 cavity. By setting the telescopic rods 18, the up-and-down reciprocating movement of the screening machine housing 13 can be further precisely limited to a fixed distance, preventing the screening machine housing 13 from colliding with the surface of the inner cavity of the base 1 during the up-and-down reciprocating movement.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
