[0018] The present invention also provides a method for using the candle recycling device, comprising the following steps:

[0019] Step 1: After the waste candles are crushed by the crushing device, they enter the melting tank from the feed port for heating and melting, so that the waste candles are transformed from solid to liquid. After the waste candles are completely melted, the discharge pipe is opened by controlling the electromagnetic valve, so that the melted candle liquid in the melting tank is discharged from the discharge pipe and falls on the filter element for filtration;

[0020] Step 2: The candle liquid filtered by the filter element enters the liquid recovery box placed in the recovery chamber to store the filtered candle liquid. After the filter element is used for a period of time, the solenoid valve is closed to stop the delivery of the candle liquid to the liquid recovery box.

At this time, the filter element moves to a position that fits with the cleaning roller;

[0022] In step four, the lifting device moves to drive the cleaning roller to move vertically downward. Due to the meshing relationship between the traveling gear at the end of the cleaning roller and the vertical rack plate on the outer wall of the lifting guide rail, the cleaning roller rotates during the downward movement, so that the cleaning roller can rotate while moving, comprehensively cleaning the surface of the filter element, and sweeping the impurities filtered on the surface of the filter element into the solid recovery box for collection.

[0023] Compared with the prior art, the technical effects of the present invention are:

[0024] (1) In the present invention, the telescopic cylinder drives the filter element to achieve position displacement through the deflection mechanism, so that the filter element can be reciprocated between two positions below the melting tank, and the filter element can be switched between the filtering position and the cleaning position. The cleaning mechanism can then clean the filter element at the cleaning position, thereby achieving automatic cleaning of the filter element, eliminating the tedious disassembly and cleaning, and improving the quality of candle liquid filtration;

[0025] (2) The present invention uses an eccentric disk in the deflection mechanism to realize the movement of the filter element along an arc track. At the same time, the special-shaped track fixed at the top of the semicircular plate in the special-shaped connecting component and the straight through groove, the driving rod and the arc groove between the connecting pipe and the cylindrical rod are arranged, so that the filter element can rotate 90 degrees when switching to the cleaning position, so that the cleaning mechanism can sweep the impurities filtered out of the filter element downward, so that the fallen impurities can be stored in the solid recovery box, which is convenient for subsequent collection and improves the cleaning effect of the filter element;

[0026] (3) The present invention configures a vertical rack plate on the lifting guide rail in the cleaning mechanism and a travel gear on the cleaning roller, so that the cleaning roller can rotate toward the filter element when moving downward, thereby achieving comprehensive cleaning of the filter element surface and improving the cleaning quality of the filter element surface.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention provides Figure 1-7The candle recycling and processing device shown in the figure includes a processing box 100, a filter element 400, a deflection mechanism and a cleaning mechanism. A crushing device 200 is fixedly provided at the top of the processing box 100, and a feed port 101 connected to the inside of the crushing device 200 is opened at the top of the processing box 100. In some embodiments, the crushing device 200 is generally composed of a crushing shell, a crushing roller and a driving unit. The crushing roller is rotatably installed in the crushing shell. The crushing roller is driven to rotate by the driving unit to crush the waste candles put into the crushing shell. The crushed waste candles enter the melting tank 300 from the feed port 101 for heating and melting, which can improve the heating and melting efficiency of the waste candles. In order to improve the efficiency, a melting tank 300 is provided at the top of the inner cavity of the processing box 100. The melting tank 300 is used to melt the waste candles. A heating component is provided in the melting tank 300 (in the prior art, electric heating wire can be used for electric heating, or water bath heating can be used for heating). A filter member 400 is movably arranged at a position below the melting tank 300. The filter member 400 is used to filter the candle liquid flowing out of the melting tank 300. A mounting groove 107 is provided on the side wall of the processing box 100. The deflection mechanism is movably installed in the mounting groove 107. A telescopic cylinder 402 is movably connected to the side wall of the processing box 100 and is located on one side of the mounting groove 107. The telescopic cylinder 402 is moved by The deflection mechanism drives the filter element 400 to swing back and forth. The cleaning mechanism is arranged on the inner side of the processing box 100. The cleaning mechanism is used to clean the impurities on the surface of the filter element 400. A partition plate 102 is fixedly connected to the bottom of the inner cavity of the processing box 100. The partition plate 102 divides the bottom of the inner cavity of the processing box 100 into a waste chamber 103 and a recovery chamber 104. A solid recovery box 106 is arranged in the waste chamber 103, and a liquid recovery box 105 is arranged in the recovery chamber 104. Through grooves connected to the waste chamber 103 and the recovery chamber 104 are opened at the bottom of both sides of the processing box 100. Box doors 108 are rotatably installed on both sides of the processing box 100 through the through grooves. The telescopic cylinder 402 is actuated to cooperate with the The transmission action of the deflection mechanism drives the filter element 400 to move along a circular trajectory, switching the position so that the filter element 400 switches from the filtering position above the liquid recovery box 105 to the cleaning position at the top of the solid recovery box 106. In this way, the surface of the filter element 400 can be cleaned by the cleaning mechanism, and the filtered solid impurities are swept into the solid recovery box 106 for storage. This not only avoids repeated disassembly and assembly of the filter element 400, but also allows the swept impurities to be collected and processed in a centralized manner, and can be cleaned after the single melted waste candle liquid in the melting tank 300 is filtered. This avoids shutdown for cleaning and speeds up the work efficiency of waste candle recycling.

[0041] Among them, a discharge pipe 301 is fixedly provided on one side of the bottom end of the melting tank 300, and the discharge pipe 301 is used to discharge the candle liquid in the melting tank 300. A solenoid valve 302 is provided on the discharge pipe 301, and the filtering position of the filter element 400 is located directly below the discharge pipe 301. The opening and closing of the discharge pipe 301 can be conveniently controlled by the solenoid valve 302, so as to control the outflow of the candle liquid in the melting tank 300.

[0042] It should be noted that the deflection mechanism includes an eccentric disk 401, which is rotatably connected to the inner side of the mounting groove 107, the end of the eccentric disk 401 protruding outward is hinged to the front end of the telescopic cylinder 402, and the tail end of the telescopic cylinder 402 is hinged to the outer wall of the processing box 100, and the eccentric disk 401 is composed of a circular plate and a round head plate, which is fixed to the side wall of the circular plate, so that when the telescopic cylinder 402 pulls the round head plate to move, it drives the circular plate to rotate, thereby driving the eccentric disk 401, and a connecting member is fixed between the eccentric disk 401 and the filter element 400; the connecting member includes a connecting pipe 405, one end of the connecting pipe 405 is fixedly connected to the side wall of the eccentric disk 401, and the other end of the connecting pipe 405 is rotatably connected to the cylindrical rod 406, and a semicircular plate 403 fixed to the inner wall of the processing box 100 is provided below the eccentric disk 401, and the semicircular plate 403 and the cylindrical rod 406 are connected. A special-shaped connecting component is provided in the connecting piece, and the special-shaped connecting component is used to drive the cylindrical rod 406 to rotate during the deflection process. By setting the special-shaped connecting component in the connecting piece, when the eccentric disk 401 rotates, the cylindrical rod 406 can be driven by the special-shaped connecting component to rotate during the deflection of the connecting pipe 405. In this way, the filter element 400 can be rotated ninety degrees when it moves to the cleaning position, so that the filter element 400 is rotated from the horizontal state to the vertical state, which can reduce the adhesion force between the impurities and the filter element 400, so that the cleaning mechanism can more conveniently clean the impurities on the filter element 400. At the same time, when the filter element 400 is in the vertical state for cleaning, the cleaned impurities can fall vertically into the solid recovery box 106 below, which is convenient for the collection of solid impurities and saves the tediousness of subsequent manual cleaning.

[0043] Furthermore, the special-shaped connecting component includes a special-shaped track 404 fixedly connected to the top of the semicircular plate 403. The cross-section of the special-shaped track 404 is U-shaped, and the special-shaped track 404 is composed of arc segments and straight segments. In this way, the filter element 400 can maintain a stable lateral state during the movement of the first half, which can prevent impurities from falling into the liquid recovery box 105 or the processing box 100. After reaching the position above the solid recovery box 106, it rotates to ensure that solid impurities enter the solid recovery box 106. A linear through groove 407 is opened at the bottom end of the connecting pipe 405, and a driving rod 408 is movably inserted in the linear through groove 407. The cylindrical rod 400 06 is provided with an arc groove 409 on the outer wall, one end of the driving rod 408 extends to the inner side of the special-shaped track 404, and the other end of the driving rod 408 extends to the inner side of the arc groove 409. The driving rod 408 is guided by the linear through groove 407, and the driving action of the special-shaped track 404 on the movement of the driving rod 408 and the driving action of the driving rod 408 on the rotation of the cylindrical rod 406 through the arc groove 409 can make the cylindrical rod 406 deflect to the rear half of the special-shaped track 404 and then start to deflect and rotate, so as to realize the steering of the filter element 400 and improve the surface cleaning effect of the filter element 400.

[0044] In a preferred embodiment, the cleaning mechanism is fixedly installed at the top position of the waste chamber 103 inside the processing box 100, and the cleaning mechanism includes a support plate 502, and the top of the support plate 502 is fixedly connected to a lifting device 503, the telescopic end of the lifting device 503 extends to the bottom of the support plate 502 and is fixedly connected to a U-shaped frame 504, and the inner side of the U-shaped frame 504 is rotatably connected to a cleaning roller 500; the two ends of the cleaning roller 500 extend to the outside of the U-shaped frame 504 respectively and are rotatably connected to a seat bearing 505, a lifting guide rail 501 is fixedly provided under the support plate 502, and a linear slide groove matching the seat bearing 505 is provided on the lifting guide rail 501, and both ends of the cleaning roller 500 are fixedly sleeved with walking Gear 506, a vertical rack plate 507 is provided on one side of the lifting guide rail 501 close to the traveling gear 506, and the outer wall of the traveling gear 506 is meshed and connected with the vertical rack plate 507. The lifting device 503 can adopt a cylinder, a hydraulic cylinder or an electric telescopic rod, which is mainly used to drive the cleaning roller 500 to rise and fall. After the filter element 400 is in place, it fits with the outer wall of the cleaning roller 500. During the descent of the cleaning roller 500, the traveling gear 506 rotates when it moves along the vertical rack plate 507, which can drive the cleaning roller 500 to rotate downward toward the filter element 400. In this way, the cleaning roller 500 can comprehensively clean the surface of the filter element 400, thereby improving the quality of cleaning the filter element 400.

[0045] Embodiment 2, the present invention also provides a method for using a candle recycling device, comprising the following steps:

[0046] Step 1: After the waste candles are crushed by the crushing device 200, they enter the melting tank 300 from the feed port 101 for heating and melting, so that the waste candles are transformed from solid to liquid. After the waste candles are completely melted, the discharge pipe 301 is controlled to open by the solenoid valve 302, so that the melted candle liquid in the melting tank 300 is discharged from the discharge pipe 301 and falls on the filter element 400 for filtration;

[0047] Step 2: The candle liquid filtered by the filter element 400 enters the liquid recovery box 105 placed in the recovery chamber 104 to store the filtered candle liquid. After the filter element 400 is used for a period of time, the solenoid valve 302 is closed to stop the delivery of the candle liquid to the liquid recovery box 105. At the same time, the telescopic cylinder 402 retracts to drive the eccentric disk 401 to rotate. The eccentric disk 401 drives the filter element 400 to move from the top of the liquid recovery box 105 to the top of the solid recovery box 106 through the connecting pipe 405 and the cylindrical rod 406 to clean the surface of the filter element 400.

[0048] Step 3: During the movement of the filter element 400, the driving rod 408 first moves along the arc track of the front half of the special-shaped track 404 to keep the filter element 400 moving smoothly, and then the driving rod 408 moves along the oblique track of the rear half of the special-shaped track 404, driving the driving rod 408 to move in the straight through groove 407 on the connecting pipe 405, so that the driving rod 408 drives the cylindrical rod 406 to rotate 90 degrees through the arc slot 409 during the movement process, so that the filter element 400 rotates from a horizontal position to a vertical position. At this time, the filter element 400 moves to a position in contact with the cleaning roller 500;

[0049] In step four, the lifting device 503 is actuated to drive the cleaning roller 500 to move vertically downward. Due to the meshing relationship between the traveling gear 506 at the end of the cleaning roller 500 and the vertical rack plate 507 on the outer wall of the lifting guide rail 501, the cleaning roller 500 rotates during the downward movement, so that the cleaning roller 500 can rotate simultaneously during the movement process, and the surface of the filter element 400 is fully cleaned, and the impurities filtered on the surface of the filter element 400 are cleaned into the solid recovery box 106 for collection.

The eccentric disk (401) drives the filter element (400) to move from above the liquid recovery box (105) to above the solid recovery box (106) through the connecting pipe (405) and the cylindrical rod (406) to clean the surface of the filter element (400). Step 3: During the movement of the filter element (400), the driving rod (408) first moves along the arc track of the front half of the special-shaped track (404) to maintain the smooth movement of the filter element (400), and then the driving rod (408) moves along the oblique track of the rear half of the special-shaped track (404), driving the driving rod (408) to move in the straight through groove (407) on the connecting pipe (405), so that the driving rod (408) drives the cylindrical rod (406) to rotate ninety degrees through the arc slot (409) during the movement process, so that the filter element (400) rotates from a horizontal position to a vertical position. At this time, the filter element (400) moves to a position where it fits with the cleaning roller (500); In step four, the lifting device (503) moves to drive the cleaning roller (500) to move vertically downward. Due to the meshing relationship between the traveling gear (506) at the end of the cleaning roller (500) and the vertical rack plate (507) on the outer wall of the lifting guide rail (501), the cleaning roller (500) rotates during the downward movement, so that the cleaning roller (500) can rotate simultaneously during the movement process, and the surface of the filter element (400) is fully cleaned, and the impurities filtered on the surface of the filter element (400) are cleaned into the solid recovery box (106) for collection.
