Description

Изобретение относится к производству строительных материалов и может быть использовано, например, на заводах силикатного кирпича, железобетонных изделий и конструкций для дробления мерзлых или слежавшихся кусков песка и других сыпучих материалов.The invention relates to the production of building materials and can be used, for example, in factories of silicate brick, reinforced concrete products and structures for crushing frozen or packed pieces of sand and other bulk materials.

Известны разнообразные конструкции устройства для дробления кусковых материалов, которые обеспечивают дробление практически всех горных пород и других кусковых материалов с пределом прочности при сжатии до 3000 кгс/см^и степенью измельчения до 40. Но в связи с их назначением для материалов с широким диапазоном прочности они громоздки, конструктивно сложны и энергоемки. Вписать их при необходимости в существующую технологическую линию не представляется _мвозможным, так как требуется значительный перепад уровней между подающим материал в дробилку и принимающим его из дробилки транспортирующими механизмами, что требует значительной производственной мощности.A variety of designs of the device for crushing lump materials are known, which provide crushing of almost all rocks and other lump materials with a compressive strength of up to 3000 kgf / cm ^ and a degree of grinding up to 40. But due to their purpose for materials with a wide range of strength, they bulky, structurally complex and energy intensive. Fill in if necessary in the existing technological line _m is not possible, since it requires a considerable level difference between the feed material to the crusher and the crusher receiving it from the conveying mechanism, which requires a large capacity.

Известно устройство, содержащее подающий ленточный транспортер и установленные на раме дробящее приспособление и привод. Оно значительно проще щековых, конусных, валковых и ' других дробилок, имеет меньшие габаритные размеры и энергоемкость (1 Однако известное устройство может работать только на мелкокусковом материале и при незначительной производительности. Как во всех валковых дробилках сГгладкими валками, максимальная крупность кусков исходного материала не может превышать 1/80 ч.диаметра валка. Тем более, что валок не имеет привода, а вращается за счет силы трения о ленту подающего конвейера и при подаче слоя материала больше толщины фрикционных накладок на концах валка или при попадании кусков материала высокой твердости валок отходит от бараз 8502 бана конвейера и фрикционные накладки не касаются его. Кроме того, наличие в устройстве.подающего конвейера несколько усложняет его конструкцию и для йего требуется дополнительная $ площадь, а для его привода дополнительные энергозатраты.A device is known comprising a feed belt conveyor and a crushing device and a drive mounted on a frame. It is much simpler than jaw, cone, roll and other crushers, has smaller overall dimensions and energy intensity (1 However, the known device can only work on small-sized material and with low productivity. As in all roller crushers with smooth rolls, the maximum size of the pieces of the starting material cannot more than 1/80 hours of roll diameter, all the more so because the roll does not have a drive, but rotates due to the friction force on the conveyor belt and when feeding a layer of material more than the thickness of the friction linings to the ends of the roll or when pieces of high hardness material get into it, the roll moves away from the baraz 8502 of the conveyor ban and the friction linings do not touch it.In addition, the presence of a feed conveyor in the device complicates its design somewhat and requires an additional $ area for it, and for its drive additional energy costs.

Цель изобретения - упрощение устройства и повышение его эксплуатационных возможностей. ЮThe purpose of the invention is to simplify the device and increase its operational capabilities. YU

Поставленная цель достигается тем, что в устройстве, содержащем подающий транспортер и установленные на раме дробящее приспособление и привод, дробящее приспособление выполнено в виде 15 приводного барабана и зубчатого валка, установленного с возможностью перемещения по наклонно смонтированным на раме направляющим.This goal is achieved by the fact that in the device containing the feed conveyor and the grinding device and the drive mounted on the frame, the grinding device is made in the form of a 15 drive drum and a gear roll mounted to move along the guide rails mounted on the frame.

Устройство работает следующим образом.The device operates as follows.

Движущийся с конвейерной лентой исходный материал при огибании лентой приводного барабана 1 конвейера про— .35 ходит через зазор S между лентой конвейера и вращающимся зубчатым валком 2, где и происходит дробление за счет составляющей силы тяжести устройства, направленной параллельно подвижной 40 раме 4. При этом необходамое усилие валка на материал (усилие дробления) выбирается в зависимости от предела щючности при сжатии кусков материала и необходимой степенью измельче- 45 ння и. обеспечивается за счет изменения наклона направляющих 5. Устройство обеспечивает захват и дробление кусков материала, равных радиусу валMoving with a conveyor belt, the starting material, when the drive drum 1 passes around the conveyor belt, passes through - .35 through the gap S between the conveyor belt and the rotating gear roller 2, where crushing occurs due to the component of the device’s gravity directed parallel to the movable 40 frame. the required roll force on the material (crushing force) is selected depending on the limit of adhesiveness when compressing pieces of material and the required degree of grinding is 45 n and. provided by changing the slope of the guides 5. The device provides for the capture and crushing of pieces of material equal to the radius of the shaft

4 :ка. При попадании кусков большого размера он первоначально пробуксовывает на ленте конвейера, а дробящий зубчатый валок 2 работает как фреза, сйимая с куска каждым зубом слой материала до тех пор, пока не произойдет его захват и дробление. При попадании материала с большим пределом прочности на сжатие, чем настроено дробящее устройство, оно откатывается на роликах по направляющим 5, предохраняя устройство от поломок, и тут же возвращается силой тяжести обратно. Величина зазора S между зубчатым валком 2 и барабаном 1 устанавливается за счет упора 6 в зависимости от размера кусков исходного материала и необходимой крупности частиц готового продукта.4: ka. When large pieces fall, it initially slips on the conveyor belt, and the crushing gear roller 2 acts as a milling cutter, a layer of material removed from the piece by each tooth until it is grabbed and crushed. If a material with a greater compressive strength exceeds the setting of the crushing device, it rolls on rollers along the guides 5, protecting the device from breakdowns, and immediately returns by gravity back. The size of the gap S between the gear roll 2 and the drum 1 is set due to the stop 6, depending on the size of the pieces of the starting material and the required particle size of the finished product.

(.54) DEVICE FOR CRUSHING MATERIALS The invention relates to the production of building materials and can be used, for example, in the factories of silicate brick, reinforced concrete products and structures for crushing frozen or packed pieces of sand and other bulk materials. Various designs of the device for crushing lump materials are known, which provide crushing of almost all rocks and other lump materials with a compressive strength of up to 3000 kgf / cm and a degree of comminution to AO. But due to their purpose in dp materials with a wide range of strength, they are cumbersome, structurally complex and energy intensive. If necessary, it is possible to inscribe them in the existing production line Hes, since a significant level difference between the feed material to the crusher and the transport mechanisms that receive it from the crusher is required, which requires considerable production capacity. A device is known that contains a feeding conveyor belt and is installed on the frame of a splitting device and an actuator. OIO is much simpler than jaw, cone, roll and other crushers, it has dimensions and power intensity fl. However, the known device can only work on small-volume material and with low productivity. As in all roll crushers with smooth rolls, the maximum size of pieces of raw material can not exceed 1/80 parts of the roll. Moreover, the roller does not have a drive, but rotates due to the friction force on the feed conveyor belt and when the layer of material is delivered more than the thickness of the friction lining on the ends of the roll or when the pieces of material of high hardness hit, the roller moves away from the bar of the conveyor and the friction does not touch . In addition, the presence of a subcontracting conveyor in the device somewhat complicates its design and additional space is required for riero and additional energy costs for its drive. The circuit of the invention is a simplification of the device and an increase in its operational capabilities. This goal is achieved by the fact that in the device containing a podkashchy conveyor and mounted on the frame a crushing device and an actuator, the wrist gear is made in the form of a driving drum and a toothed roller installed with the ability to move along a directionally inclined direction on the frame. The drawing shows the device. The drive drum 1 device consists of a toothed roller 2 and a drive 3. The toothed roller 2 and the drive 3 mounted No. 1 on the frame 4, which can move along obliquely mounted guides 5. Dp provide the necessary clearance between the toothed roller and the driving drum of the conveyor to the guides 5 an adjustable stop 6 is installed. The device works in a deductive manner. The raw material moving with the conveyor belt, when the conveyor belt I bends around the conveyor drum I, passes through the gap S between the conveyor belt and the rotating toothed roller 2, where crushing takes place due to the component gravity of the device directed parallel to the movable frame 4. the material (crushing force) is selected, depending on the limit of shyuchnosti when compressing pieces of material and the required degree of grinding and HttH. is provided by changing the inclination of the guides 5. The device ensures the capture and crushing of pieces of material equal to the radius of the shaft 34 ka. When large pieces hit, the measure initially slips on the conveyor belt, and the 1tsi toothed roll 2 acts like a milling cutter, simulating a layer of material with each tooth until it is grabbed and crushed. When a material with a higher compressive strength is hit, the crushing device is adjusted, it rolls back on rollers in directions 5, protects the device from breakage, and immediately returns to gravity. The size of the gap S between the toothed roller 2 and the drum 1 is established by the stop 6, depending on the size of the pieces of the starting material and the required particle size of the finished product. Implementing the present invention only in the silicate brick industry allows for the use in winter of lumps of frozen sand, which are sifted out. It does not require the relocation of existing equipment. The device can be mounted above the drive drum of any belt conveyor for supplying sand to production, i.e. with minimal cost. Claims device for crushing materials, containing feed belt conveyor and mounted on the frame crushing device and drive, characterized in that, in order to simplify the device and increase its operational capabilities, the crushing device is made in the form of a drive drum and a toothed roller installed with the ability to move along rails mounted obliquely on the frame.
