Environment-friendly oily sludge mixing and crushing device
Technical Field
The invention relates to the technical field of oily sludge treatment, in particular to an environment-friendly oily sludge mixing and crushing device.
Background
The oily sludge refers to sludge mixed with crude oil, various finished oils, residual oil and other heavy oils. The oil-containing sludge is not inherent in nature, but inevitably causes crude oil or finished oil to leak to the ground, deposit to the ocean, lake, river bottom, mix with soil, water and the like to form a mixture of oil, soil, water, even other mixed pollutants due to various accidents, improper operation, old equipment damage, corrosion and the like in the process of oil exploration, exploitation, processing, storage and transportation. The oily sludge is harmful to human bodies, plants and water organisms and is one of the main pollutants in the petroleum and petrochemical industries. The oil-containing sludge has high content of petroleum pollutants and high viscosity, and is difficult to disperse manually, so that a large amount of oil sludge blocks exist in a treatment plant, and therefore, when the oil-containing sludge is treated, the oil-containing sludge needs to be mechanically crushed, and the subsequent treatment processes such as decomposition and extraction are facilitated.

In this embodiment, the inner bottom of the outer cylinder 1 is provided with a motor 5, and the lower cover 7 is connected with an output shaft of the motor 5. The upper cover 4 is connected to the lower cover 7 through threads to seal the base 11, the planet wheels 8 and the compression force storage device, so that sundries are prevented from entering the transmission system, and the service life is prolonged. The top and the bottom of the outer barrel 1 are respectively provided with a feeding hole and a discharging hole, so that feeding and discharging are facilitated.
With the above embodiment, the use principle and the working process of the present invention are as follows:
in the rest state, as shown in FIG. 3, the device is at rest with power spring 21 most relaxed, expanding the four links 9 to the outermost limit positions. After the machine is started, the motor 5 rotates clockwise and drives the lower cover 7 to rotate clockwise, and the lower cover 7 drives the blade 3 to rotate clockwise (corresponding to the first direction) relative to the filter disc 2 through the planet wheel 8, the compression force storage device and the base 11.
When the device normally works, when the crushing resistance is increased to stop the blade 3, the lower cover 7 rotates to drive the planet wheel 8 to rotate clockwise, the planet wheel 8 rotates to drive the connecting rod 9 to move, the connecting rod 9 contracts inwards to be closed, the connecting rod 9 pushes the transmission arm 12 to move inwards to compress the power storage spring 21 to enable the power storage spring 21 to store power, the lower cover 7 can drive the base 11 to rotate, the planet wheel 8 stops rotating, the planet wheel 8 and the base 11 continue to rotate along with the lower cover 7, and then the blade 3 is driven to rotate to be crushed (as shown in fig. 4). When the crushing resistance is further increased (as shown in fig. 5), the blade 3 stops again, the planet wheel 8 rotates again, the connecting rods 9 continue to contract inwards and approach, and the power storage spring 21 is further compressed until the planet wheel 8 and the base 11 can rotate with the lower cover 7 again.
The resistance of the blade 3 is increased, so that the lower cover 7 cannot drive the blade 3 to rotate when the power storage of the power storage spring 21 is maximum, namely the blade 3 is completely blocked by the resistance of the blade 3, if the power storage spring 21 is not at the maximum compression position at this time, the lower cover 7 continuously drives the planetary wheel 8 to rotate, the planetary wheel 8 rotates to drive the connecting rod 9 to continuously contract inwards and draw close, the transmission arm 12 is pushed to move inwards to continuously compress the power storage spring 21, the power storage of the power storage spring 21 is gradually increased until the planetary wheel 8 rotates to a first preset position, namely the connecting rod 9 is at the extreme position of the innermost end, the power storage spring 21 cannot be compressed by the transmission arm 12, and the power storage of the power storage spring 21 is maximum (as shown in fig. 6). Thereafter, the planet wheel 8 continues to rotate and rotate through the first preset position, the connecting rod 9 expands outwards, the force storage spring 21 releases the stored force, so that the planet wheel 8 rotates in a clockwise direction in an accelerating manner and then rolls backwards along the transmission gear ring 19 relative to the lower cover 7 (the rotating force of the planet wheel 8 is not enough to drive the lower cover 7 to rotate in an accelerating manner together with the lower cover), namely, the planet wheel rolls in a counterclockwise direction, and the base 11 and the blade 3 are driven to rotate in a counterclockwise direction (corresponding to the second direction) relative to the filter disc 2, namely, the blade 3 retreats for a certain distance. After the planetary wheel 8 rotates to the second preset position, that is, the extreme position of the outermost end of the link 9, the power storage spring 21 stops releasing the power (as shown in fig. 7). The rear lower cover 7 drives the blade 3 to rotate clockwise (corresponding to the first direction) through the planet wheel 8, the compression force storage device and the base 11, and the blade 3 has no load until impacting an obstacle clamped on the filter disc 2. If the obstacle is not cleared, the lower cover 7 drives the planet wheel 8 to rotate again, so that the power of the power spring 21 is gradually increased, and the obstacle is hit repeatedly until the obstacle is broken or cleared.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
