Abstract

The present invention relates to the technical field of filtering equipment, and specifically to a tea oil production filtering device, which comprises a bracket, a filter cartridge, a filter disc and a fixed cartridge. After the tea oil enters the filter chamber, the process of the tea oil entering the filter disc is a filtering process, and impurities in the tea oil can be blocked on the outside of the filter disc. Under the action of the pressure difference, the filter disc is deformed, and the filtered tea oil is discharged from the filter cartridge under the joint action of the oil delivery pipe and the oil discharge pipe; when the amount of tea oil discharged at the oil discharge pipe is reduced, impurities are accumulated on the filter disc. At this time, the filter disc with impurity accumulation no longer filters the tea oil, and the pressure difference between the inside and outside of the filter disc gradually decreases. During the resetting process of the filter disc, part of the impurities accumulated on the filter disc enter the processing chamber through the reflux port under the action of its own gravity, and the processing component centrally processes the impurities entering the processing chamber, thereby reducing the frequency of disassembly and cleaning, and further reducing the impact on the tea oil production efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a tea oil production filtering device. Background Art

[0002] As a natural and healthy edible oil, tea oil is highly favored by consumers because it is rich in unsaturated fatty acids and vitamin E. The production process of tea oil involves extracting oil from tea seeds. During this process, the tea oil needs to be filtered to remove impurities and ensure the purity and quality of the product.

[0003] Existing tea oil filtering devices mainly use a combination of mechanical filtration and pneumatic multi-layer filtration to remove solid impurities in tea oil layer by layer through multi-layer filter screens. However, in actual use, the structure of the pneumatic multi-layer filter is relatively complex, and each layer of filter screen needs to work independently, which makes it very troublesome to clean; usually each layer of filter screen needs to be disassembled layer by layer for cleaning and maintenance, which not only consumes a lot of manpower and time, but also may cause damage to the filter screen due to improper operation during the disassembly process, further increasing the maintenance cost; at the same time, frequent disassembly and cleaning work can easily lead to a decrease in filtration efficiency, and the machine often needs to be shut down during the cleaning process, which leads to the stagnation of the production line, seriously affecting the production efficiency and economic benefits of tea oil.

[0008] Furthermore, the pitch of the conveying auger gradually decreases from bottom to top; an oil guide pipe is arranged at the upper end of the driving rod, and the driving rod is oil-absorbing cotton. The conveying auger can squeeze out the impurities entering the processing chamber.

[0028] like Figures 1 to 6 As shown, a tea oil production filtering device provided by an embodiment of the present invention includes a bracket 110, a filter cartridge 120, a filter disc 130 and a fixing cartridge 150.

[0029] The bracket 110 is provided with a plurality of moving wheels, and the convenience of moving the bracket 110 can be improved by providing a plurality of moving wheels.

[0030] The filter cartridge 120 is fixedly arranged on the bracket 110. The filter cartridge 120 is vertically arranged on the bracket 110. The interior of the filter cartridge 120 is hollow. The hollow chamber inside the filter cartridge 120 is a filter chamber 121. The upper end of the filter cartridge 120 is provided with an opening that connects the external environment and the filter chamber 121. The opening at the upper end of the filter cartridge 120 is an inspection port. The upper end of the filter cartridge 120 is provided with a cover plate 122 that can block the upper end opening of the filter cartridge 120. When the equipment in the filter chamber 121 needs to be repaired or cleaned, the cover plate 122 is unblocked from blocking the inspection port at the upper end of the filter cartridge 120. When filtering tea oil, the cover plate 122 is in a state of blocking the inspection port at the upper end of the filter cartridge 120. Further, a lock buckle and a sealing strip are provided on the cover plate 122. Under the action of the lock buckle and the sealing strip, the cover plate 122 can tightly seal the inspection port at the upper end of the filter cartridge 120. The cover plate 122 is provided with an oil injection hole 123 that penetrates from top to bottom, and tea oil can be continuously injected into the filter cavity 121 through the oil injection hole 123, and the tea oil can be in a high pressure state in the filter cavity 121. The side wall of the filter cartridge 120 is provided with a plurality of oil drain pipes 140 that connect the external environment and the filter cavity 121, and the oil drain pipes 140 are used to discharge the filtered tea oil.

[0031] There are multiple filter discs 130, and the multiple filter discs 130 are coaxially arranged in the filter cavity 121. The multiple filter discs 130 are arranged at intervals in the filter cavity 121. Figure 3 As shown, the filter disc 130 is a slightly arc-shaped plate with an opening facing upwards, and the inside of the filter disc 130 is hollow, so tea oil can enter the inside of the filter disc 130 through the side walls around the filter disc 130, and impurities in the tea oil can be intercepted outside the filter disc 130. A support is provided inside the filter disc 130, and the filter disc 130 can be deformed. Specifically, when the tea oil in the filter cavity 121 is in a high-pressure state, the tea oil can enter the inside of the filter disc 130 through the side walls of the filter disc 130. Under the action of the pressure difference between the inside and outside of the filter disc 130, the upper and lower side walls of the filter disc 130 are deformed. Under the action of the support, the upper and lower side walls of the filter disc 130 are prevented from abutting against each other, thereby ensuring that the tea oil entering the inside of the filter disc 130 has a flow channel. The interior of each filter disc 130 is connected to an oil drain pipe 140 via an oil delivery pipe. By providing the oil delivery pipe, it is ensured that the tea oil entering the filter chamber 121 will not be directly discharged from the filter chamber 121 through the oil drain pipe 140. At the same time, the tea oil pressure in the filter chamber 121 can be increased.

[0032] The fixed cylinder 150 is coaxially arranged in the filter cavity 121, and the fixed cylinder 150 coaxially penetrates a plurality of filter discs 130, and the fixed cylinder 150 is fixedly connected to the plurality of filter discs 130. The interior of the fixed cylinder 150 is hollow, and the hollow chamber inside the fixed cylinder 150 is the processing cavity 151. The upper end of the processing cavity 151 is always connected to the filter cavity 121, and the upper end of the fixed cylinder 150 is above the uppermost filter disc 130. The fixed cylinder 150 is fixedly connected to the inner side wall of the filter cylinder 120. The side wall of the fixed cylinder 150 is provided with a plurality of reflux ports 152 connecting the processing cavity 151 and the filter cavity 121, wherein each reflux port 152 is arranged between two adjacent filter discs 130. Specifically, the number of the reflux ports 152 is the number of the filter discs 130 minus one. For example, if the number of the filter discs 130 is five, the number of the reflux ports 152 is four, and each reflux port 152 is arranged between two adjacent filter discs 130. The fixed cylinder 150 is provided with a plugging member, which can simultaneously block multiple reflux ports 152. When filtering tea oil, the plugging member is in a state of blocking multiple reflux ports 152, and the tea oil in the filter chamber 121 cannot enter the processing chamber 151. The plugging member can also unblock any reflux port 152. Specifically, as the tea oil is filtered, impurities in the tea oil are easily attached to the surface of the filter disc 130. At this time, the impurities attached to the surface of the filter disc 130 will prevent the tea oil from entering the inside of the filter disc 130. If the amount of tea oil discharged from a certain oil drain pipe 140 is reduced, it proves that the amount of impurities accumulated on the surface of the corresponding filter disc 130 is too much. At this time, the oil drain pipe 140 with reduced tea oil discharge is blocked, and the oil drain pipe 140 with reduced tea oil discharge is blocked. 40 The differential pressure inside and outside the filter disc 130 connected through the oil pipeline gradually decreases, and the filter disc 130 gradually resets and deforms, and the impurities accumulated on the filter disc 130 vibrate. At the same time, the control plugging member is unblocked to discharge the reduced amount of tea oil through the return port 152 above the filter disc 130 connected through the oil pipeline. Since the filter disc 130 is a slightly curved plate with an opening facing upward, the impurities after vibration can enter the processing chamber 151 through the return port 152 under the action of their own gravity. A processing member is arranged in the processing chamber 151, and the processing member can centrally process the impurities entering the processing chamber 151, thereby reducing the frequency of disassembly and cleaning.

[0033] The tea oil production filtering device of the present invention continuously conveys the tea oil to the filter chamber 121 when filtering the tea oil, ensuring that the filter chamber 121 maintains a high pressure state. After the tea oil enters the filter chamber 121, the tea oil passes through the side wall of the filter disc 130 and enters the interior of the filter disc 130. The process of the tea oil entering the interior of the filter disc 130 is a filtering process. Impurities in the tea oil can be blocked on the outside of the filter disc 130. Under the action of the pressure difference, the filter disc 130 is deformed. By setting a support member, the upper and lower sides of the filter disc 130 can be prevented from being tightly attached. The filtered tea oil is discharged from the filter cartridge 120 under the joint action of the oil delivery pipe and the oil discharge pipe 140; the tea oil is discharged at the oil discharge pipe 140. When the amount decreases, impurities accumulate on the filter disc 130. At this time, the oil drain pipe 140 is blocked, and the sealing piece is used to unblock the reflux port 152 above the corresponding filter disc 130. Then, the filter disc 130 with accumulated impurities no longer filters the tea oil, and the pressure difference between the inside and outside of the filter disc 130 gradually decreases. The filter disc 130 begins to reset actively. During the resetting process of the filter disc 130, some impurities accumulated on the filter disc 130 enter the processing chamber 151 through the reflux port 152 under the action of their own gravity. The processing piece centrally processes the impurities entering the processing chamber 151, thereby reducing the frequency of disassembly and cleaning, and further reducing the impact on the tea oil production efficiency.

[0034] In one embodiment, the processing part includes a driving rod 210 and a conveying auger 220. The driving rod 210 is coaxially rotatably arranged in the processing chamber 151. The conveying auger 220 is spirally shaped and coaxially sleeved on the outside of the driving rod 210. The conveying auger 220 has an inner side wall and an outer side wall. The inner side wall of the conveying auger 220 is fixedly connected to the driving rod 210. The outer side wall of the conveying auger 220 abuts against the inner side wall of the fixed cylinder 150. When the driving rod 210 rotates in the processing chamber 151, the conveying auger 220 moves in the processing chamber 151. The upper end of the fixed cylinder 150 is provided with an opening connecting the processing chamber 151 and the filtering chamber 121. Under the action of the upper end opening of the fixed cylinder 150, during the tea oil filtering process, tea oil is present in both the processing chamber 151 and the filtering chamber 121, and the pressure of the tea oil in the processing chamber 151 is the same as the pressure of the tea oil in the filtering chamber 121. The upper end of the fixed cylinder 150 is arranged above the top filter disc 130, and the conveying auger 220 can convey the impurities entering the processing chamber 151 to the top filter disc 130 through the opening at the upper end of the fixed cylinder 150. As the tea oil is filtered, after working for a period of time, only the top filter disc 130 needs to be disassembled and cleaned, reducing the frequency of disassembly and cleaning of other filter discs 130.

[0035] In one of the embodiments, the pitch of the conveying auger 220 gradually decreases from bottom to top. When impurities enter the processing chamber 151, the driving rod 210 begins to rotate in the processing chamber 151, and the conveying auger 220 begins to convey the impurities from bottom to top. Since the pitch of the conveying auger 220 is in a gradual state, and the pitch of the conveying auger 220 gradually decreases from bottom to top, when the conveying auger 220 conveys impurities from bottom to top, the pitch change of the conveying auger 220 can squeeze the impurities. An oil guide pipe 250 is provided at the upper end of the driving rod 210, one end of the oil guide pipe 250 is above the uppermost filter plate 130, and the other end of the oil guide pipe 250 is fixedly connected to the driving rod 210. The driving rod 210 is an oil-absorbing cotton. In the process of the conveying auger 220 squeezing the impurities, the impurities contain tea oil, and the tea oil in the impurities is squeezed outwardly, and the tea oil in the impurities can be absorbed by the oil-absorbing cotton. It is easy to understand that under the action of the conveying auger 220 squeezing the impurities, the tea oil in the impurities can enter the driving rod 210. In addition, the processing chamber 151 is always in a state of being filled with tea oil. When the conveying auger 220 squeezes the tea oil in the impurities, under the action of the oil pressure inside the driving rod 210, the tea oil entering the driving rod 210 can flow upward into the oil guide pipe 250, and the tea oil entering the driving rod 210 can be conveyed to the top of the uppermost filter plate 130 through the oil guide pipe 250.

[0036] In one embodiment, the blocking member includes a blocking sleeve 230, a plug-in ring groove is arranged inside the side wall of the fixed cylinder 150, the blocking sleeve 230 is rotatably arranged in the plug-in ring groove, and a plurality of connecting grooves 231 are arranged on the blocking sleeve 230, each connecting groove 231 is arranged corresponding to a reflux port 152, specifically, the number of the connecting grooves 231 is the same as the number of the reflux ports 152, and the horizontal height of each connecting groove 231 is the same as the horizontal height of a reflux port 152. When the sealing sleeve 230 rotates, the sealing sleeve 230 can block multiple reflux ports 152, or one of the connecting grooves 231 on the sealing sleeve 230 is connected to a reflux port 152. In the initial state, the sealing sleeve 230 is in a state of blocking multiple reflux ports 152. When the amount of impurities accumulated on one of the filter discs 130 reaches a level that affects the entry of tea oil into the filter disc 130, the sealing sleeve 230 rotates a certain angle so that a reflux port 152 above the filter disc 130 is connected to the processing chamber 151. At the same time, under the action of the shape of the filter disc 130 itself, it is ensured that the impurities that affect the entry of tea oil into the filter disc 130 smoothly enter the processing chamber 151 under the action of their own gravity.

[0037] In one embodiment, each oil drain pipe 140 is provided with a blocking valve 240, and the blocking valve 240 has a first state of blocking the oil drain pipe 140 and a second state of conducting the oil drain pipe 140. In the initial state, the blocking valve 240 on each oil drain pipe 140 is in the second state. Specifically, when the blocking valve 240 is in the first state, the tea oil in the filter disc 130 cannot be discharged from the filter cavity 121 through the oil delivery pipe and the oil drain pipe 140, and when the blocking valve 240 is in the second state, the tea oil in the filter disc 130 can be discharged from the filter cavity 121 through the oil delivery pipe and the oil drain pipe 140. When the sealing valve 240 on the oil drain pipe 140 is in the second state, there is a large pressure difference between the inside and outside of the filter disc 130. When the sealing valve 240 on the oil drain pipe 140 is in the first state, there is a small pressure difference between the inside and outside of the filter disc 130. Further, when there is a large pressure difference between the inside and outside of the filter disc 130, the upper side wall and the lower side wall of the filter disc 130 are close to each other. When there is a small pressure difference between the inside and outside of the filter disc 130, the upper side wall and the lower side wall of the filter disc 130 are parallel to each other. When the sealing valve 240 on the oil drain pipe 140 is switched from the second state to the first state, the upper side wall and the side wall of the filter disc 130 will move away from each other, and impurities attached to the upper side wall and the lower side wall of the filter disc 130 will oscillate, thereby facilitating the impurities to detach from the upper side wall and the lower side wall of the filter disc 130.

[0038] In one embodiment, each oil drain pipe 140 is provided with a flow detector, and the flow detector can detect the flow rate of the tea oil discharged from the oil drain pipe 140. Specifically, the flow rate of the tea oil discharged from the oil drain pipe 140 is obtained by: the amount of tea oil discharged from the oil drain pipe 140 per unit time. When the flow rate of the tea oil discharged from any oil drain pipe 140 is less than the first preset value, the blocking valve 240 on the oil drain pipe 140 is switched from the second state to the first state. Specifically, each oil drain pipe 140 is provided with a controller, and the controller can receive the detection data of the flow detector on the oil drain pipe 140. The controller can compare the received data with the first preset value. At the same time, the controller can control the blocking valve 240 on the oil drain pipe 140 to switch from the second state to the first state when the flow rate of the tea oil discharged from the oil drain pipe 140 is less than the first preset value. At the same time, when the blocking valve 240 on any oil drain pipe 140 is switched from the second state to the first state, it proves that the amount of impurities accumulated on the filter disk 130 connected to the oil drain pipe 140 through the oil pipeline has reached the level that affects the tea oil entering the filter disk 130. At this time, the blocking sleeve 230 is controlled to rotate a certain angle to ensure that the oil drain pipe 140 is connected to the filter disk 130 through a reflux port 152 above the oil drain pipe connected to the oil pipeline and the connecting groove 231 on the blocking sleeve 230. At the same time, under the action of the shape of the filter disk 130 itself, it is ensured that the impurities that affect the tea oil entering the filter disk 130 can smoothly enter the processing chamber 151 through the reflux port 152 under the action of its own gravity.

[0039] In one embodiment, a driving source is provided on the bracket 110, and the driving source can drive the driving rod 210, and the driving source can also drive the blocking sleeve 230. Specifically, the driving source includes a first driving motor and a second driving motor, the first driving motor is fixedly provided on the bracket 110, and the first driving motor is used to drive the driving rod 210 to rotate around its own axis, and the second driving motor is fixedly provided on the bracket 110, and the second driving motor is used to drive the blocking sleeve 230 to rotate around its own axis. In other embodiments, the driving source can also include an active motor 310 and a transmission disk 320, the active motor 310 is fixedly arranged on the bracket 110, the power output shaft of the active motor 310 is arranged horizontally, a first bevel wheel 330 is fixedly arranged on the power output shaft of the active motor 310, the lower end of the driving rod 210 passes through the lower end surface of the fixed cylinder 150, and a second bevel wheel 340 is arranged at the lower end of the driving rod 210, wherein the outer side walls of the first bevel wheel 330 and the second bevel wheel 340 are both provided with tooth grooves, the first bevel wheel 330 is always meshed with the second bevel wheel 340, and the active motor 310 can directly drive the driving rod 210 to rotate around its own axis. The transmission disc 320 is coaxially fixedly connected to the lower end of the driving rod 210, and the transmission disc 320 can rotate synchronously with the driving rod 210. The plug-in ring groove arranged inside the side wall of the fixing cylinder 150 opens downward, and the lower end of the blocking sleeve 230 is arranged on the outer side of the fixing cylinder 150. A tightening cylinder 350 is arranged at the lower end of the blocking sleeve 230. The length of the tightening cylinder 350 can be changed. The tightening cylinder 350 is arranged vertically. When the length of the tightening cylinder 350 increases, the lower end of the tightening cylinder 350 can tighten the transmission disc 320. When the transmission disc 320 rotates, the tightening cylinder 350 extends for a period of time. After the blocking sleeve 230 rotates a certain angle, the lower end of the tightening cylinder 350 disengages from the transmission disc 320.

[0040] In one embodiment, the support member includes a support plate 410 and a support block 420, and the support plate 410 is coaxially fixed inside the filter plate 130; a plurality of support blocks 420 are provided, and the plurality of support blocks 420 are evenly arranged on the support plate 410, and there is a gap between any two adjacent support blocks 420. When the filter plate 130 filters the tea oil, there is a pressure difference between the inside and the outside of the filter plate 130. Under the action of the pressure difference between the inside and the outside of the filter plate 130, the upper side wall and the lower side wall of the filter plate 130 both abut against the support block 420. Under the action of the support plate 410 and the support block 420, the upper side wall and the lower side wall of the filter plate 130 are prevented from abutting against each other.

[0041] In one embodiment, the support plate 410 can divide the internal cavity of the filter plate 130 into a relatively isolated first chamber 131 and a second chamber 132; wherein the first chamber 131 is arranged above the second chamber 132, and the oil drain pipe 140 is connected to the first chamber 131 through the oil delivery pipe; a connecting pipe 430 is arranged between two adjacent filter plates 130, and the connecting pipe 430 can connect the second chamber 132 in one of the filter plates 130 with the first chamber 131 in the adjacent lower filter plate 130. Specifically, when one of the filter plates 130 is blocked by impurities, a reflux port 152 above the filter plate 130 is unblocked by the plugging sleeve 230, and during the vibration of the upper and lower side walls of the filter plate 130, the impurities on the lower side wall of the filter plate 130 fall onto the upper side wall of the adjacent lower filter plate 130 under the action of their own gravity, and the impurities falling on the adjacent lower filter plate 130 cannot enter the processing chamber 151 through the reflux port 152 in time. At this time, the interior of the filter disc 130 is divided into a first chamber 131 and a second chamber 132 by using a support disc 410. When the upper surface of one of the filter discs 130 is blocked by impurities, according to the setting of the filter disc 130's own structure, the position that is prone to blockage is on the upper side wall of the filter disc 130. The upper side wall of the filter disc 130 oscillates simultaneously with the lower side wall of the adjacent upper filter disc 130, and the lower side wall of the filter disc 130 remains in contact with the support block 420 on the support disc 410, thereby avoiding interference with the normal operation of other filter discs 130 during the impurity processing process.

[0042] In one of the embodiments, a pressure sensor is provided at the oil filling hole 123, and the pressure sensor is used to detect the pressure in the filter chamber 121. When the tea oil is filtered, the pressure in the filter chamber 121 is in a constant state, ensuring that the tea oil can smoothly pass through the upper side wall or the lower side wall of the filter plate 130.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
