Description
Technical Field
The utility model relates to a processing technology field extracts oil, especially relates to an extract oil and use clearance sieve.
Background
An oil press is a machine that presses oil from oil by increasing the temperature and activating the oil molecules under the action of a mechanical external force. Can be divided into a household oil press, a hydraulic press oil press, a screw oil press, a novel hydraulic oil press, a high-efficiency fine filtration oil press and a full-automatic oil press.
The oil press is in the time of extracting oil, need filter the seed of pre-pressed oil, current screening method is to use sieve to sieve the manual work and rock and filter, like this only can separate the impurity of seed kind, but need filter different moulds when classifying different kind of seeds, thereby the screening time has been wasted, inconvenient screening when mixing different kind of seeds in the seed, device in addition is when sieving the seed, need use the pole to stir, smash the seed of usefulness of extracting oil easily like this, thereby inconvenient classifying different seeds, therefore, need design one kind and extract oil and use clearance sieve to solve above-mentioned problem.
No. CN 207025786U's china is exclusively used in 2018 and is disclosed a clearance sieve for extracting oil 23 days 2, include sleeve, apron, hold a section of thick bamboo and motor, apron upside middle part threaded connection has accepts the bag, sleeve lateral wall downside symmetry installs the bracing piece, the welding of sleeve downside has a hopper, it has the fixed block to hold symmetrical welding between a section of thick bamboo and the sleeve, hold a section of thick bamboo lateral wall from the top down and install first filter screen, second filter screen and third filter screen respectively, the side shaft nature is connected with the pivot on the motor, pivot skin weld has the spiral leaf, it has the inlet pipe to hold a surface symmetry welding, the welding of inlet pipe outer end has the feeder hopper. This patent is convenient for drive the spiral leaf and promote the seed through setting up the motor to save physical power, used three filter screen, be convenient for sieve different kind of seeds, be convenient for extract different oil. However, the three filter screens of the patent are fixedly installed, only oil materials with the same shape and size can be filtered, and different kinds of oil materials cannot be screened.
Chinese patent publication No. CN204429663U discloses an oil screening device for oil press equipment, which includes a bracket with a universal wheel at the bottom; one end of the bracket is provided with a splitter box, and the other end is provided with a collecting hopper; the bracket is movably connected with the obliquely arranged screen frame through a movable connecting rod; the bottom end of the screen frame is respectively and mutually spliced with the grading screen through clamping grooves; the bottom of the screen frame is connected with an eccentric wheel through a connecting rod; the eccentric wheel is in transmission connection with a motor provided with a speed reducer through a belt. Because the screen frame is fixedly spliced with the grading screen through the clamping grooves, the screen frame can be sequentially arranged according to the sizes of meshes of the grading screen; moreover, classifying screens with different apertures and shapes can be inserted according to the shape and the size of the raw materials such as peanuts, corns and the like, so that the equipment can be used for screening different varieties of raw materials; the screened high-quality raw materials are collected at the collecting hopper to extract oil, so that the quality of oil products is improved, and different varieties of raw materials can be considered. This patent realizes the change of different screen cloths through the grafting mode to the realization is to the screening of different varieties raw materials, but to the vibration filtering's clearance sieve for extracting oil, there is the risk of droing with the screen cloth of the mutual grafting of draw-in groove, can not guarantee stable raw materials clearance work.
