Description

Technical Field

[0001] The invention relates to the technical field of oil pressing and deslagging, and in particular to an oil pressing and deslagging device and method. Background Art

[0002] Oil pressing mainly uses pressing equipment to squeeze oil to squeeze out the oil in the oil. During the pressing process, the pressure on the oil gradually increases. When the pressure reaches a certain level, the oil will be separated from the oil. The oil pressing residue discharge device separates and discharges the oil residue during the oil pressing process to ensure the quality and pressing efficiency of the oil.

[0003] In the existing oil pressing and slag discharge device, the slag generated is mostly collected by using a slag discharge structure during the pressing process. When a certain amount of slag is collected, the collected slag is cleaned manually. At the same time, in order to ensure the continuous and stable oil leakage of the filter plate, the filter mechanism needs to be cleaned regularly.

[0004] The existing oil pressing and slag discharge device is used for slag discharge. Since a certain amount of oil is still mixed in the slag, in order to reasonably collect and utilize the oil, a corresponding filter plate is usually set in the oil collection structure to leak the oil. However, due to the small amount of oil mixed in the slag, it takes a long time to collect the oil only by free dripping on the filter plate. In actual continuous operation, when the slag accumulates to a certain extent, it needs to be discharged immediately. This will result in a low collection efficiency of the oil inside the slag, resulting in a low resource utilization rate for raw materials and unnecessary waste of resources.

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0028] See also Figures 1 to 7 The present invention provides a grease pressing and slag discharge device and method, comprising a collecting main frame 1, a screw press 2 and a discharge assembly, wherein the discharge assembly comprises a connecting frame 3, a lead-out frame 4, a throw-out filter frame 5, an extruding member 6 and a rotating member 7, wherein the extruding member 6 comprises a supporting cylinder 601, a supporting member 602, a pressing cylinder 603 and a pressing member 604, and the rotating member 7 comprises a sleeve gear 701, a rotating gear 702 and a rotating motor 703. The above-mentioned scheme solves the problem of using an existing grease pressing and slag discharge device for slag discharge. Since a certain amount of oil is still mixed in the slag, in order to reasonably collect and utilize the oil, a corresponding filter plate is generally set in the structure for collecting the oil to leak oil. However, since the amount of oil mixed in the slag is small, it takes a long time to collect the oil only by free dripping on the filter plate. In actual continuous operation, when the slag accumulates to a certain extent, it needs to be discharged immediately, which will result in a low collection efficiency of the oil inside the slag, resulting in a low resource utilization rate for raw materials, resulting in unnecessary waste of resources.

[0029] Furthermore, the connecting frame 3 is connected to the screw press 2 and is installed on the collecting main frame 1, the lead-out frame 4 is connected to the connecting frame 3, the throw-out filter frame 5 is rotatably installed in the lead-out frame 4, the extrusion member 6 is connected to the lead-out frame 4, and is used to support and squeeze the slag entering the inside of the throw-out filter frame 5, and the rotating member 7 is connected to the lead-out frame 4, and is used to drive the throw-out filter frame 5 to rotate in the lead-out frame 4.

[0030] Specifically, the screw press 2 is internally provided with corresponding screw rods and electrodes for driving the screw rods, and the connecting frame 3 is used to guide the slag filtered by the screw press 2 so that the slag enters the lead-out frame 4. When the slag falls into the lead-out frame 4, it is collected and squeezed for a second time to extract oil under the action of the ejection filter frame 5 and the extrusion component 6. The ejection filter frame 5 rotates under the action of the rotating component 7, so the squeezed oil and the oil attached to the slag itself can be quickly ejected, and then the secondarily extracted oil is recycled through the step collection chamber provided on the lead-out frame 4 in conjunction with the corresponding lead-out pipe, thereby realizing the ability to quickly complete the discharge of the slag and the collection and utilization of the remaining oil in the slag through the provided components, thereby avoiding the waste of corresponding resources.

[0031] Furthermore, the supporting cylinder 601 is installed on the lead-out frame 4; the supporting member 602 is rotatably installed on the output end of the supporting cylinder 601; the pressing cylinder 603 is installed on the connecting frame 3; and the pressing member 604 is rotatably installed on the output end of the pressing cylinder 603.

[0032] When the present embodiment is in use, the supporting cylinder 601 and the pressing cylinder 603 are respectively mounted on the lead-out frame 4 and the connecting frame 3, and the output ends of the supporting cylinder 601 and the pressing cylinder 603 are also respectively rotatably provided with the supporting member 602 and the pressing member 604, the supporting member 602 and the pressing member 604 are both cylindrical in shape, the supporting member 602 is adapted to the circular through groove in the middle of the pressing member 604 and the ejection filter frame 5, the supporting member 602 is a protruding conical cylinder, and the pressing member 604 is a concave conical groove cylinder, and the truncated cone provided on the supporting member 602 matches the conical groove provided on the pressing member 604;

[0033] During normal operation, the oil squeezed by the screw press 2 can be directly introduced into the collecting main frame 1 through the connecting frame 3, and then the residue filtered out from the connecting frame 3 is introduced into the guide frame 4 through the corresponding mechanism. At the same time, the support member 602 blocks and seals the bottom of the ejection filter frame 5 under the drive of the downward pressure cylinder 603, so that the residue introduced from the guide frame 4 will fall onto the surface of the support member 602, so that the fallen residue can be collected by the circular filter hole frame composed of the support member 602 and the ejection filter frame 5. Then, the downward pressure cylinder 603 drives the downward pressure member 604 to move downward, and the residue supported by the support member 602 is squeezed for the second time by the downward pressure member 604, so that the residue can be more thoroughly discharged.

[0034] It should be noted that, in order to be able to judge and monitor the working process and working state of the supporting cylinder 601 and the pressing cylinder 603, the supporting cylinder 601 and the pressing cylinder 603 can be provided with corresponding air pressure sensing mechanisms to monitor the air pressure data outputted from their own output ends, so as to better control the driving of the two cylinders. When the slag falls onto the supporting member 602, the weight of the slag itself will give the supporting member 602 and the supporting cylinder 601 a corresponding pressure. When the pressing cylinder 603 drives the pressing member 604 to start pressing downward, once the pressing member 604 contacts the slag for squeezing, the pressure on the supporting cylinder 601 and the corresponding squeezing on the output end of the pressing cylinder 603 can be judged by detecting the pressure changes inside the two cylinders, thereby completing the secondary squeezing and oil extraction of the slag.

[0035] After the slag is squeezed to extract oil, the supporting cylinder 601 can drive the supporting member 602 to move downward, so that the supporting member 602 is moved out of the throwing-out filter frame 5. At this time, the slag will follow the supporting member 602 to be discharged from the outlet frame 4, thereby completing the automatic discharge of the slag.

[0036] Furthermore, the sleeve gear 701 is fixedly sleeved on the ejection filter frame 5; the rotating gear 702 is meshed with the sleeve gear 701 and is rotatably mounted on the lead-out frame 4; the output shaft of the rotating motor 703 is connected to the rotating gear 702, and the rotating motor 703 is fixedly mounted on the lead-out frame 4.

[0037] When the present embodiment is in use, the sleeve gear 701 is fixedly sleeved on the top of the ejection filter frame 5, the rotating gear 702 is meshed with the sleeve gear 701, and the rotating gear 702 is driven by the arranged rotating motor 703, so that after the lower pressing member 604 moves downward to squeeze out the oil from the slag above the supporting member 602, the ejection filter frame 5 can be driven by the driving motor to rotate following the rotating gear 702 and the sleeve gear 701. At the same time, since the supporting member 602 and the lower pressing member 604 are rotationally connected to the output ends of the two cylinders, the compressed slag and the supporting member 602 and the lower pressing member 604 will also rotate with the ejection filter frame 5, so that the oil produced by the secondary squeezing of the slag and the oil attached to the slag can be quickly discharged, and then collected by the step collection chamber arranged on the lead-out frame 4, so that the slag discharge is more efficient.

[0038] Preferably, the working assembly provided by the present invention also includes a lifting bracket 8, a double-layer filter arc plate 9, a lifting drive mechanism 10, an ejection component 11 and a blowing component 12, the ejection component 11 includes a double-plate push frame 1101 and a pushing mechanism 1102, the blowing component 12 includes a rotating jet frame 1201, an air pump 1202, a driving gear 1203 and a driving component 1204, the driving component 1204 includes a guide bracket 12041, a transition gear 12042, a sliding rack 12043, a rotating drive component 12044 and a driving component 12045.

[0039] Furthermore, the lifting bracket 8 is slidably installed on the connecting frame 3; the double-layer filter arc plate 9 is fixedly installed on the side of the lifting bracket 8 close to the screw press 2; the lifting drive mechanism 10 is connected to the connecting frame 3, and is used to drive the lifting bracket 8 to move; the pushing component 11 is connected to the connecting frame 3, and is used to push out and clean the impurities filtered from the double-layer filter arc plate 9; the blowing component 12 is connected to the screw press 2, and is used to blow out the residual slag and oil inside the screw press 2.

[0040] Furthermore, the double-plate pushing frame 1101 is slidably installed on one side of the connecting frame 3; the pushing mechanism 1102 is connected to the connecting frame 3 and is used to drive the double-plate pushing frame 1101 to move.

[0041] When the present embodiment is in use, the double-layer filter arc plate 9 is matched with the internal spiral tube circular groove of the screw press 2. Under normal circumstances, a certain gap is required between the screw and the spiral tube circular groove of the screw press 2 to ensure normal cooperation with the raw material. The set gap cannot be too large or too small. If the gap between the screw and the spiral tube is too large, the dehydration effect will be reduced, and if the gap is too small, it may increase the wear and energy consumption of the equipment, and even cause equipment failure. Therefore, the double-layer filter arc plate 9 is matched with the bottom through groove at the end of the spiral tube of the screw press 2;

[0042] The double-layer filter arc plate 9 is provided with a through slot in the middle, and the upper and lower plates separated by the empty slot of the double-layer filter arc plate 9 are provided with different filter hole plates, and the filter holes of the upper plate of the double-layer filter arc plate 9 are larger than the filter holes of the lower plate, so that the accumulated slag can be filtered twice;

[0043] The bottom of the double-layer filter arc plate 9 is fixed to the lifting bracket 8, and the lifting bracket 8 is driven by the lifting drive mechanism 10. The lifting drive mechanism 10 is mainly composed of a corresponding screw and a motor that drives the screw to rotate, so that the corresponding plate can be driven by the corresponding screw mechanism, so that the user can drive the lifting bracket 8 and the double-layer filter arc plate 9 to move through the lifting drive mechanism 10. When the screw press 2 is completed, the double-layer filter arc plate 9 can cooperate with the lifting drive mechanism 10 to move the accumulated slag material to the bottom of the connecting frame 3 , then the double-plate pushing rack 1101 will push the slag on the double-layer filter arc plate 9 into the lead-out rack 4 under the action of the pushing mechanism 1102. The pushing mechanism 1102 is similar in principle to the lifting drive mechanism 10, and both drive the corresponding plates through the screw drive principle. The double-plate pushing rack 1101 is provided with a scraping plate that matches the double-layer filter surface of the double-layer filter arc plate 9, so that the impurities filtered on the two filter surfaces of the double-layer filter arc plate 9 can be pushed into the lead-out rack 4, and the two filter surfaces of the double-layer filter arc plate 9 can also be quickly cleaned.

[0044] Furthermore, the rotating jet frame 1201 is rotatably installed in the screw press 2; the air pump 1202 is connected to the rotating jet frame 1201; the driving gear 1203 is fixedly mounted on the rotating jet frame 1201; the driving component 1204 is connected to the screw pressing frame, and is used to drive the driving gear 1203 to rotate back and forth within a certain arc.

[0045] Furthermore, the guide bracket 12041 is fixedly installed under the screw press 2; the filter gear is meshed with the driving gear 1203 and is rotatably installed on the guide bracket 12041; the sliding rack 12043 is meshed with the transition gear 12042 and is slidably installed on the guide bracket 12041; the rotating drive member 12044 is installed at the bottom of the screw press 2; the driving member 12045 is rotationally linked to the sliding rack 12043 and is connected to the rotating drive member 12044.

[0046] When the present embodiment is in use, the rotating jet frame 1201 is arranged on one side of the feed end of the screw press 2, and the rotating jet frame 1201 is composed of an annular connecting frame and a plurality of jet nozzles, and the rotating jet frame 1201 is connected to the air outlet end of the air pump 1202 through an arranged air pipe;

[0047] The outer fixed sleeve of the annular connecting frame provided with the rotating jet frame 1201 is provided with the driving gear 1203, the driving gear 1203 is meshed with the filtering gear, and the filtering gear is driven by the sliding rack 12043, the sliding rack 12043 can move in the corresponding direction by cooperating with the guide bracket 12041, the rotating driving member 12044 is composed of a motor and a plate member that can be driven by the motor, and the two sides of the driving member 12045 are respectively connected with the sliding rack 12043 and the rotating driving member 12044. 044 is provided with a plate rotation connection. When the plate of the rotating driving member 12044 is rotated by the corresponding motor, the driving member 12045 can drive the sliding rack 12043 to move back and forth under the drive of the rotating driving member 12044, and then drive the transition gear 12042 and the driving gear 1203 to rotate back and forth through the back and forth movement of the sliding rack 12043. In this way, the rotating jet frame 1201 can be driven to perform corresponding back and forth rotation in the screw press 2 through the back and forth rotation of the driving gear 1203;

[0048] Since the rotating jet frame 1201 is provided with a plurality of jet nozzles, the rotating jet frame 1201 only needs to rotate a certain arc to cooperate with the air pump 1202 to complete a circle of blowing on the inner and outer sides of the screw press 2. Therefore, in actual operation, when the user discharges the slag material, the air pump 1202 can be used to introduce the gas through the rotating jet frame 1201, and then the oil and part of the slag material attached to the inner wall of the screw press 2 can be blown out by the back and forth rotation of the rotating jet frame 1201, so that the discharge of the slag material and the collection of the oil material can be better achieved.

[0049] See also Figure 8, a grease pressing and deslagging device and method, using the grease pressing and deslagging device and method, comprising the following steps:

[0050] S1: The imported raw materials are squeezed to extract oil through the screw press 2. The squeezed oil is filtered through the double-layer filter arc plate 9 and then introduced into the collection main frame 1 through the connecting frame 3 to complete the collection;

[0051] S2: After the slag concentrated on the double-layer filter arc plate 9 is squeezed, the lifting drive mechanism 10 can drive the lifting bracket 8 to move downward, and then the lifting bracket 8 moves downward to drive the double-layer filter arc plate 9 to move the accumulated slag to the bottom of the connecting frame 3;

[0052] S3: When the slag follows the double-layer filter arc plate 9 and moves down to the corresponding position, the pushing member 11 pushes the slag into the output rack 4;

[0053] S4: The ejection filter frame 5 provided in the lead-out frame 4 cooperates with the extrusion member 6 to perform secondary extrusion on the collected slag, and then the ejection filter frame 5 is driven to rotate by the rotating member 7 to eject the oil extruded from the secondary extrusion and the oil attached to the slag for collection.
