Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a mineral processing conveying equipment. Background Technology

[0002] After coal or other ores are excavated, they undergo preliminary crushing and are then transported to a predetermined location using a conveyor belt. The pre-crushed ore is not uniform in size and requires further screening and crushing. Therefore, the ore needs to be screened according to its size during the transportation process.

[0003] Some screening equipment typically uses guide plates to sort ores of different sizes to different locations. However, it has been found in production that if there are continuous large ores, the ores may accumulate on the conveyor belt, which could damage the equipment.

[0004] For example, Chinese patent application number CN201921761351.9 discloses a conveyor belt capable of classifying and storing coal mines by size; specifically, it discloses that "a larger coal mine is moved to the right by a first conveyor belt and falls from the guide plate onto the top of a second conveyor belt"; if such equipment encounters a continuous large-sized ore, it may cause the ore to accumulate on the conveyor belt, which may damage the equipment.

[0005] For example, Chinese patent application number CN202222119094.7 discloses a screening device for crushed ore. Specifically, it describes a process where "a leather conveyor belt carries several scraper plates and surface wire brushes to the inner wall of the screening chamber, moving them to the outer top of the waste slag trough. There, they come into contact with a large amount of falling waste slag fragments, which are then pushed into the waste slag trough by the scraper plates and surface wire brushes. The waste slag fragments fall from the trough into the waste bin for collection, and the filtered, crushed ore falls from the other end of the leather conveyor belt." Similarly, this type of equipment may experience ore accumulation on the conveyor belt when encountering continuously large-sized ores, potentially damaging the equipment. Utility Model Content

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Please refer to Figures 1 to 5As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a mineral processing and conveying device.

[0032] Among them, the scraper 46 of the scraper conveyor belt is movable, which can scrape the ore that does not conform to the size on the conveyor belt and send it to the preset position. The ore will not accumulate and can protect the equipment.

[0033] This application provides a mineral processing conveying device, including a feeding device, a dust removal device, a mineral processing device, and a conveying device. The feeding device includes a feeding hopper and a cover plate, with the cover plate covering the feeding hopper and having a feed inlet. The dust removal device includes a water tank, an atomizing head disposed in the feeding hopper, and a water pump connected to the water tank. The atomizing head has several nozzles. The water pump pumps water from the water tank into the atomizing head. The conveying device includes a conveyor belt and a first motor connected to the conveyor belt, the first motor driving the conveyor belt to move. The input end of the conveyor belt is disposed below the discharge port of the feeding hopper. The mineral processing device includes a first mounting frame, a second mounting frame, and a scraper conveyor belt. The second mounting frame is height-adjustable and disposed above the first mounting frame. The scraper conveyor belt is disposed on the second mounting frame. The feeding device is used for feeding materials, and the dust removal device is used for removing dust from the ore to reduce dust levels. The conveying device is used for conveying the ore. When this mineral processing conveying device is working: 1. The ore enters the hopper from the feed inlet. 2. A water pump connected to the water tank draws water and delivers it to the atomizing head through a pipeline. The nozzles of the atomizing head spray water onto the ore, thus reducing dust. 3. The conveyor belt transports the ore. Because the scraper is at a certain height above the conveyor belt, ore that meets the required size passes under the scraper, while ore that does not meet the size is scraped off the conveyor belt and falls into the designed position. The output shaft of the first motor drives the conveyor belt through a gearbox. The conveyor belt, also known as a transport belt, is a rubber and fiber, metal composite product, or a plastic and fabric composite product used in belt conveyors to carry and transport materials. The first mounting frame is fixed to the frame with screws, and the second mounting frame is adjustable in height to the first mounting frame with screws. By adjusting the height of the second mounting frame, the height of the scraper conveyor belt can be adjusted. This design can be used to screen ores of different sizes. By setting scraper conveyor belts of different heights, multiple screenings of different sizes can be performed. This structure is simple and easy to maintain. The water pump and the water tank are connected by a pipe 34. A mounting plate 45 is provided between the scraper conveyor belt 44 and the second mounting frame, and screws are used to fix the scraper conveyor belt and the second mounting frame to the mounting plate 45.

[0034] Preferably, a vibrating motor is installed on the inclined wall panel of the feeding hopper, and the discharge port of the feeding hopper is inclined towards the conveyor belt. The vibrating motor is fixed to the feeding hopper with screws. The vibrating motor can vibrate the inclined wall panel, thereby causing the entire hopper to vibrate. This design can prevent ore from accumulating in the hopper and facilitate the complete emptying of the hopper.

[0035] Preferably, the inclination angle of the inclined wall panel 24 is between 15° and 45°, such as 15°, 25°, 30°, 45°, etc. The inclined wall panel 24 can act as a buffer, helping to protect the hopper. In this embodiment, the scraper has a certain degree of curvature, which can act as a buffer and smoothly scrape the material away from the conveyor belt.

[0036] Preferably, the cover plate is detachably mounted on the feeding hopper; the feed inlet is detachably equipped with a screening grid. The cover plate is mounted on the feeding hopper with screws, and its detachability facilitates maintenance. The screening grid is mounted on the feed inlet with screws, and the screening grid also serves to screen and protect the hopper.

[0037] Preferably, baffles are provided on both sides of the conveyor belt; at least one baffle is provided with a screening opening; and a downward-sloping screening hopper is provided on the screening opening. The baffles can block the ore within the conveyor belt and prevent it from falling off. The scrapers are arranged vertically, and the scraper conveyor belt scrapes the ore to the screening hopper through the movement of the scrapers. The screening hopper then continues to transport the screened ore to the next process.

[0038] Preferably, the angle between the second mounting frame and the forward direction of the conveyor belt is between 30-45°, and the scraper of the scraper conveyor belt can scrape the ore on the conveyor belt into the screen hopper. This avoids the ore from impacting the scraper head-on. The ore contacts the scraper at a certain angle, and then the scraper scrapes the ore into the screen hopper. This design is very simple.

[0039] Preferably, the first mounting frame is screwed onto the frame and has several adjustment holes; the end of the second mounting frame passes through the first mounting frame, and the adjustment screw passes through the adjustment hole. The scraper conveyor belt includes a conveyor chain, scrapers, and a second motor; the scraper conveyor belt is screwed onto the second mounting frame; the scrapers are mounted on the conveyor chain; the second motor drives the conveyor chain to move. The scrapers are mounted on the conveyor chain, and the second motor drives the conveyor chain to move through a gearbox, thus enabling the scrapers to move. A scraper conveyor belt is a conveying device that uses a scraper chain to push materials along a trough. The height of the second mounting frame is adjusted by screws on the first mounting frame, and different heights can accommodate different ore sizes. In this embodiment, the mineral processing device has three sets; the height of the three sets of scrapers gradually increases along the conveyor belt direction, thus allowing for the screening of ores of multiple sizes.

[0040] Preferably, the frame includes a first leg, a second leg, and an X-shaped connecting rod; the first leg and the second leg are connected by the X-shaped connecting rod; a first support opening is provided at the top of the first leg; a second support opening is provided at the top of the second leg; the first support opening supports the first end of the conveyor belt; the second support opening supports the second end of the conveyor belt. The first leg, the second leg, and the X-shaped connecting rod are fixed together with screws. The X-shaped connecting rod provides good stability and strong load-bearing capacity. The first and second support openings facilitate the installation of the conveyor belt, which can be installed on the frame with screws.

[0041] In summary, the key design feature of this invention lies in the addition of a scraper conveyor belt above the main conveyor belt. The scraper of the scraper conveyor belt can scrape the ore on the conveyor belt to a preset position. Because the scraper is movable, the ore will not accumulate during screening, thus protecting the equipment.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
