Description

Technical Field

[0001] The utility model relates to the technical field of grinding mills, and more specifically, to a grinding mill for crushing glass fiber reinforced plastics. Background Art

[0002] The grinding mill is an advanced grinding equipment designed and developed on the basis of widely adopting advanced technologies at home and abroad and combining many years of experience in producing various grinding mills and vertical grinding mills. It is a kind of equipment that integrates crushing, drying and grinding.

[0003] It is an ideal equipment for the grinding industry that integrates grading and conveying, and can be widely used in cement, electricity, metallurgy,

[0004] In the chemical and non-metallic mineral industries, fiberglass is typically crushed and ground into the desired powder form. Recycled fiberglass is typically sold and sold in a vertical mill. During the grinding process, large pieces of fiberglass inevitably form, causing blockage in the mill. Existing vertical mills lack screening capabilities, and if there are large pieces of fiberglass among the cullet, this can easily cause blockage, impacting processing efficiency.

[0005] After searching, the Chinese patent with authorization announcement number CN216396626U discloses a vertical mill for recycling waste glass. The structure uses a vibration mechanism to vibrate the screening mechanism. After screening, the broken glass in the screening mechanism enters the vertical mill body through the feed hopper for grinding. Because the screening mechanism prevents large pieces of broken glass from entering the vertical mill body, it prevents the vertical mill body from being blocked and affecting the processing efficiency.

[0006] However, when this structure is actually used, the vibration device and the waste glass raw materials themselves are quite heavy. Each time the waste glass raw materials are vibrated, the spring will be damaged, resulting in a short service life of the vibration device. The spring must be replaced frequently, which not only increases operating costs but also affects processing efficiency. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a grinding mill for crushing glass fiber reinforced plastics to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] The grinding mill for crushing glass fiber reinforced plastics comprises a grinding box, two limit plates are fixedly provided inside the grinding box, two grinding wheels are provided between the two limit plates, one end of the two grinding wheels is provided with a motor 1, and the motor 1 is fixedly connected to the outside of the grinding box, a feed port is fixedly provided above the grinding box, an opening door is provided at the opening of the feed port, the opening door is connected to one side of the feed port by a hinge, an auxiliary block is fixedly provided on the surface of the opening door, a processing box is provided below the grinding box, a sieve plate is provided between the processing box and the grinding box, one end of the sieve plate is fixedly connected to the auxiliary plate, the sieve plate is slidably connected to the bottom of the grinding box, a rotating rod is provided inside the processing box, a plurality of fan blades are provided on the surface of the rotating rod, one end of the rotating rod is provided with a motor 2, and the motor 2 is fixedly connected to the outer surface of the processing box.

[0010] It can be seen that in the above structure, after the fiberglass is thrown into the grinding box through the feed port, the grinding wheel grinds the fiberglass to achieve the purpose of grinding, and the rotating rod drives the fan blade to rotate, thereby facilitating the collection of the ground fiberglass.

[0011] In order to recover and filter the dusty fiberglass above the processing box, preferably, a recovery pipe is fixedly connected to one side of the processing box, a filter is provided inside the recovery pipe, a recovery box is fixedly connected to one side of the recovery pipe, a suction fan is provided on one side of the recovery box, and a dust removal bag is provided inside the recovery box.

[0012] In order to collect the filtered dusty fiberglass separately, preferably, a connecting pipe 1 is fixedly connected below the recovery pipe, a connecting pipe 2 is fixedly connected below the recovery box, a collecting box 1 is fixedly connected below the connecting pipe 1, and a collecting box 2 is fixedly connected below the connecting pipe 2.

[0013] In order to facilitate the removal of dusty fiberglass in the collection box, preferably, a drawer box 1 is provided inside the collection box 1, the drawer box 1 is slidably connected to the collection box 1, and a handle 1 is provided on one side of the drawer box 1; a drawer box 2 is provided inside the collection box 2, the drawer box 2 is slidably connected to the collection box 2, and a handle 2 is provided on one side of the drawer box 2.

[0014] In order to better collect the fiberglass that falls below during the rotation of the fan blades, preferably, a baffle is provided below the inner cavity of the processing box, and the baffle is inclined, and a box cover is provided at the bottom of the processing box.

[0015] In order to facilitate the pulling out of the screen plate and closing one side of the grinding box, preferably, a slot is provided on one side of the grinding box, a shield is provided above the slot, and limiting rods are slidably connected on both sides of the shield. A buckle 1 is fixedly provided on the surface of the shield, and a buckle 2 is fixedly provided on one side of the grinding box, and the buckle 1 and the buckle 2 can be buckled with each other.

[0016] In order to increase the stability of the equipment during operation, preferably, a plurality of supporting legs are provided at the bottom of the processing box, the first collecting box and the second collecting box.

[0017] The technical effects and advantages of this utility model are:

[0018] By setting up a rotating rod and a fan blade structure, the rotating rod starts to rotate, and then drives the fan blade to start rotating. Since the dust is very light, the dust will be carried to the upper part of the processing box. When the suction fan is turned on, the fiberglass reinforced plastics that have been ground into dust at a high altitude will be sucked into the recovery pipe and finally enter the collection box, thereby realizing the collection of the dusty fiberglass reinforced plastics;

[0019] Secondly, by removing the sieve plate, the large pieces of FRP that have been screened out can be ground again, which improves the grinding quality of the FRP. This recycling method will not cause damage to the parts of the grinding mill. At the same time, it is convenient to recycle FRP raw materials and clean the grinding mill, reducing operating costs while improving the work efficiency of staff.

[0020] In the process of inhaling dusty FRP, the FRP that has not been fully ground can be collected into a collection box through filtering through a filter, so that separate collection is achieved, thereby improving work efficiency and quality. By arranging a pumping box structure in the collection box, the FRP can be conveniently collected and taken out. By arranging an inclined baffle in the inner cavity of the processing box, when the dusty FRP falls, it can be easily collected. BRIEF DESCRIPTION OF THE DRAWINGS

The box cover 28 is opened to take out the fallen dusty fiberglass, thereby realizing the recycling of the dusty fiberglass. Among them, if there is fiberglass that is not ground sufficiently, it can be ground again, and finally the grinding work of the fiberglass is completed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
