Description

Technical Field

[0001] The present invention relates to the technical field of chestnut cleaning, and more particularly to a rinsing and draining device for chestnut processing. Background Art

[0002] Sugar-roasted chestnuts are a popular food, and their processing requires strict requirements. Freshly picked chestnuts often have dirt and impurities on their surface, and must be thoroughly cleaned and properly air-dried before entering the subsequent frying process. Among them, efficient and thorough cleaning is the key step to ensure the hygiene and quality of sugar-roasted chestnuts.

[0003] In the prior art, a variety of special equipment for chestnut cleaning has been developed and applied; for example, Chinese patent publication No. CN209693998U discloses a chestnut processing cleaning device; the device generally includes a base, a collection box, a cleaning box, a drying chamber and other main parts; its working principle is roughly as follows: the chestnuts are cleaned in the cleaning box by water flow and possible mechanical action (such as driven by a rotating shaft), and the cleaned sewage is directly discharged from the device through the drain outlet; after cleaning, the chestnuts are transferred or unloaded into an independent drying chamber for drying, and the drying chamber may be equipped with support blocks, hot air or other static drying means; although this type of design realizes the cleaning and drying functions of chestnuts to a certain extent, it is considered to improve convenience and cleaning efficiency.

[0004] However, after analysis, such existing cleaning devices have the following obvious technical defects: The device adopts a split structure design of cleaning box and drying chamber; after completing the chestnut cleaning process, the cleaning water needs to be drained first, and then the chestnuts are transferred to the heating chamber for drying; the current design has the following defects: the cleaning water is one-time use and cannot be recycled, resulting in waste of water resources; the stirring device only acts on the cleaning link, and the drying process adopts a static drying method, which fails to fully utilize the kinetic energy output potential of the stirring device; this design leads to low overall energy efficiency utilization of the equipment and waste of resources.

[0007] Furthermore, the side walls and bottom walls of the separation cylinder are provided with holes, the inner diameter of the holes in the bottom wall is larger than that in the side walls, and the holes in the side walls of the separation cylinder are distributed in a longitudinal array, and their range completely covers the lifting stroke of the filter plate.

[0008] Furthermore, the plug-in unit adopts a split structure, which includes a plug-in connector and a support rod; the bottom end of the plug-in connector is connected to the lower plate rack by plugging and pulling, and it passes through the hole in the bottom wall of the separation cylinder and is threadedly connected to the support rod; the top end of the support rod is connected to the upper plate rack by plugging and pulling, and the bottom end is provided with a support handle with a leakage hole.

[0009] Furthermore, the bottom wall of the inner grid lining plate can be rotatably connected to the surface of the filter plate.

[0010] Furthermore, the side wall of the separation cylinder is provided with a discharge port located above the filter plate when statically suspended, and a rotatably adjustable aperture regulator is configured on its periphery: it is composed of a rigidly connected rotating ring and an arc-shaped gate, both of which are rotatably clamped in the outer ring groove of the separation cylinder.

[0012] Furthermore, the inner diameter of the opening of the inner side wall of the collecting ring pipe is larger than the size of the discharge port of the side wall of the chassis, and a slit structure is provided between the intercepting plate and the outer wall of the separation cylinder.

[0016] Technical effects and advantages of the present invention: 1. This invention uses a traction connection mechanism to drive the separation drum downward, allowing the plate frame to engage the intermittent lifting platform, triggering a dual cleaning mechanism. A multi-stage drive shaft drives the rotating transmission member, causing the recursive section to oscillate up and down with the filter plates, accelerating sludge removal. The filter plates are linked to the inner grid lining and outer grid cover, which alternately open and close to achieve circumferential rotation of the plates. Combined with the dynamic dredging of holes by the insert, this creates an oscillation-tumbling synergistic cleaning process, significantly improving cleaning efficiency and preventing clogging.

[0017] 2. This invention uses a traction connection mechanism to pull the separation drum upward, freeing the plate frame from the intermittent lifting platform. The recursive pusher and filter plates fall freely and are held in place by support rods. The inner grid lining plate is pulled away from the outer grid sleeve, closing the grid opening. As the multi-stage drive shaft rotates, centrifugal dehydration is generated, prompting water to be efficiently discharged through the holes in the side walls of the separation drum, achieving rapid switching between cleaning and draining modes and highly efficient dehydration.

[0018] 3. This invention switches from draining mode to unloading mode by separating the discharge port of the separation drum with a curved gate and unblocking the collecting ring pipe. When the closed centrifugal turning mechanism rotates with the multi-stage drive shaft, generating centrifugal force, the chestnuts are discharged sequentially through the discharge port, the collecting ring pipe, and the radial pipe, achieving efficient and automated unloading.

DETAILED DESCRIPTION

[0038] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The chestnut processing rinsing and draining device involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Reference Figure 1 - Figure 5The present invention provides a rinsing and draining device for chestnut processing, comprising a chassis 1, the interior of which is divided into two chambers, the upper one being a drainage chamber and the lower one being a cleaning chamber, the bottom wall of the cleaning chamber being fixedly mounted with a base, on which a transmission part 3 is assembled; a separation cylinder 4 which can reciprocate between the drainage chamber and the cleaning chamber in a vertical direction is provided at the center position of the chassis 1, the top of which is connected to an external traction device through a traction connection mechanism 9, and the bottom of which is equipped with a recursive part 5 extending downward; in particular, the top of the recursive part 5 is movably extended into the interior of the separation cylinder 4 and is detachably connected to a filter plate 6, a centrifugal turning mechanism 7 is arranged directly above the filter plate 6, and a multi-stage transmission shaft 8 which can be coaxially matched with the centrifugal turning mechanism 7 is provided at the center of the separation cylinder 4, and the multi-stage transmission shaft 8 passes through the filter plate 6 and the recursive part 5 and then cooperates with the transmission part 3 for transmission.

[0040] It should be noted that in this embodiment, the bottom of the chassis 1 is rigidly connected to the support base 2, and a drive device is fixedly installed on the inner side of the support base 2. The drive device is preferably a servo motor. The power output shaft of the servo motor is connected to the multi-stage transmission shaft 8 via a coupling to form a fixed mechanical assembly. Specifically, the coupling and the bottom end of the inner shaft section 83 in the multi-stage transmission shaft 8 are rigidly connected without relative displacement. The multi-stage transmission shaft 8 is a multi-stage telescopic structure nested from outside to inside, which is composed of an outer shaft section 81, a middle shaft section 82 and an inner shaft section 83. The sections are connected by vertical sliding joints to achieve axial relative motion. Figure 12 ; Ensure that the multi-stage transmission shaft 8 can avoid interference with the lifting movement of the separation cylinder 4 when transmitting torque to the centrifugal turning mechanism 7; The traction connection mechanism 9 consists of a pull rod 91, a carrier plate 92 and a traction part 93. The pull rod 91 is distributed along the circumference, with the top end converging at the center of the bottom wall of the carrier plate 92 and the bottom end extending radially and rigidly connected to the inner wall of the top end of the separation drum 4. The carrier plate 92 adopts a double-layer relatively rotatable structure, and the traction part 93 can be a rope. When the separation drum 4 is deflected by the friction force of the centrifugal turning mechanism 7, the carrier plate 92 can effectively isolate the movement and prevent the traction part 93 from being entangled with the rope. The top of the carrier plate 92 is rigidly connected to the traction part 93, and the top of the traction part 93 is connected to the traction device. Or the gravity setting of the separation drum 4 at least makes it impossible for the friction force exerted by the centrifugal turning mechanism 7 to trigger its deflection movement; Alternatively, the pull rod 91, the carrier plate 92 and the traction part 93 may be fixed in a rigid connection manner to form an integral non-rotatable structure, wherein the traction part 93 is in the form of a connecting rod to effectively suppress the deflection movement of the separation barrel 4 caused by the friction force applied by the centrifugal turning mechanism 7; The traction device is preferably a linear drive system, such as a winding mechanism or a screw transmission mechanism, which pulls up or lowers the separation drum 4 through a traction connection mechanism 9 rigidly connected thereto, thereby achieving corresponding lifting and lowering actions.

[0041] Reference Figure 3 - Figure 8 、 Figure 13 - Figure 18 The side wall and bottom wall of the separation cylinder 4 are both provided with holes, and the inner diameter of the hole in the bottom wall is larger than the inner diameter of the hole in the side wall; The bottom of the inner cavity of the separation cylinder 4 is equipped with a recursive part 5, which is composed of two upper and lower double-layer plate racks 51, respectively located on the inner and outer sides of the bottom wall of the separation cylinder 4, and detachably connected by a through-plug 52 passing through the hole in the bottom wall; the filter plate 6 is fixedly installed on the top wall of the upper plate rack 51, so that the recursive part 5 can carry the filter plate 6 to achieve synchronous lifting movement; The centrifugal turning mechanism 7 arranged above the filter plate 6 consists of an outer grid sleeve 71 and an inner grid lining 72: the outer grid sleeve 71 is clamped in the inner ring groove of the separation cylinder 4 by rotation, and the inner grid lining 72 is movably nested in the outer grid sleeve 71 and can extend downward; both surfaces are provided with grid opening structures that can be aligned with each other.

[0042] It should be noted that in this embodiment, the holes on the side wall of the separation cylinder 4 are distributed in a longitudinal array, and their range completely covers the lifting stroke of the filter plate 6; In order to optimize the travel limit of the filter plate 6 as the recursive part 5 descends and the function of clearing the hole in the bottom wall of the separation cylinder 4, the insertion plug 52 adopts a split structure: it includes a plug connector 521 and a support rod 522; the bottom end of the plug connector 521 is connected to the lower plate frame 51 in a plug-in manner (snap-in plug-in fixation), which passes through the hole in the bottom wall of the separation cylinder 4 and is threadedly connected to the support rod 522; the top end of the support rod 522 is connected to the upper plate frame 51 by plugging and pulling, and the bottom end of the support rod 522 is provided with a support handle with a leakage hole. When the support handle is stuck above the hole in the bottom wall of the separation cylinder 4, it can limit the downward limit of the recursive part 5 and the filter plate 6 to achieve stable hovering, and prevent the hole from being completely closed through the leakage hole. In order to ensure that the lifting and lowering movement of the filter plate 6 can timely carry out the adaptive extension of the inner grid lining plate 72, the bottom wall of the inner grid lining plate 72 can be rotatably connected (rotating and snap-fitting) to the surface of the filter plate 6. This connection method ensures that the inner grid lining plate 72 is synchronously lifted and lowered with the filter plate 6, and is fully compatible with the circumferential rotation movement of the inner grid lining plate 72 in conjunction with the multi-stage transmission shaft 8; The inner shaft section 83 is rigidly connected to the inner grid lining plate 72 and may not contact the inner grid lining plate 72 .

[0043] Reference Figure 9 - Figure 12 The transmission part 3 is composed of a rotating transmission member 31 and an intermittent lifting platform 32. The rotating transmission member 31 is rotatably mounted on the bottom wall of the chassis 1 through a bottom base, and its top forms a transmission connection with the intermittent lifting platform 32, so that the intermittent lifting platform 32 can realize intermittent lifting movement.

[0044] It should be noted that in this embodiment, the rotating transmission member 31 is composed of a turntable 311 and a lifting drive wheel 312 that cooperate with each other: the turntable 311 is fixed to the base of the bottom wall of the chassis 1 by a rotating clamping method, and the edge of the connecting groove on its top is equipped with the lifting drive wheel 312. The connecting groove and the bottom of the intermittent lifting platform 32 form a movable nesting cooperation, together forming a closed chamber for the lifting drive wheel 312 to perform sealed movement; at the same time, the intermittent lifting platform 32 adopts a structural setting of an inclined section of the bottom wall and a receiving groove on the top wall; To reduce the friction between the lifting drive wheel 312 and the intermittent lifting platform 32, the lifting drive wheel 312 is composed of a roller 3121 and a positioning frame 3122, wherein the roller 3121 is rotatably mounted on the positioning frame 3122, and the positioning frame 3122 is fixedly mounted in the connecting groove of the turntable 311. When the lifting drive wheel 312 moves circumferentially with the multi-stage transmission shaft 8, the roller 3121 and the intermittent lifting platform 32 are in rolling contact to achieve periodic lifting and releasing actions, effectively reducing the friction loss between the two. The turntable 311 is rigidly connected to the inner shaft section 83; the multi-stage transmission shaft 8 moves from bottom to top through the intermittent lifting platform 32, the bottom wall of the separation cylinder 4, the recursive part 5 and the filter plate 6; To optimize the discharge efficiency of chestnuts after draining, the side wall of the separation drum 4 is provided with a discharge port located above the filter plate 6 when in static suspension. The outer periphery of the discharge port is provided with a rotatable and adjustable aperture regulator 11: it consists of a rigidly connected rotating ring 111 and a radial gate 112, both of which are rotatably engaged in the outer ring groove of the separation drum 4. By rotating and adjusting the radial gate 112, the discharge port can be aligned or closed, realizing rapid opening and closing control. The caliber regulator 11 is further provided with an adjustment handle 113 fixedly connected to the rotating ring 111 as an operating handle. An operation window is correspondingly provided on the side wall of the chassis 1. The operator applies force to the adjustment handle 113 through the operation window to achieve circumferential push, thereby accurately controlling the rotation angle of the arc gate 112 to adjust the opening and closing state of the discharge port. The drain chamber is circumferentially equipped with a drain guide 10. When the separation drum 4 is raised to the highest point of the drain chamber and stops, the drain guide 10 can be aligned with the discharge port. The drain guide 10 consists of a collecting ring 101, a radial tube 102, a cutoff plate 103, and a lock 104. The radial tube 102 is fixedly installed in the chassis 1 and rigidly connected to the collecting ring 101. The bottom walls of the collecting ring 101 and the radial tube 102 are structurally configured to gradually decline from the inside to the outside. A longitudinally slidable cutoff plate 103 is provided on the inside of the collecting ring 101, and a lock 104 for locking the cutoff plate 103 is installed on the top wall of the collecting ring 101. The inner diameter of the opening of the inner wall of the collecting ring pipe 101 is larger than the size of the discharge opening of the side wall of the chassis 1; Furthermore, a slit structure of a specific width is retained between the intercepting plate 103 and the outer wall of the separation cylinder 4. This design ensures that the holes on the side wall of the separation cylinder 4 are always unobstructed in the drainage mode, avoiding physical obstruction by the intercepting plate 103.

[0045] Working principle of the present invention: The device has three working modes: cleaning mode (corresponding to Figure 2 - Figure 4 、 Figure 13 Structural morphology shown), draining mode (corresponding to Figure 15 - Figure 16 The structural form shown) and the unloading mode (corresponding to Figure 17 - Figure 18 The structural morphology shown); When the equipment is in the cleaning mode, the traction device delivers the separation cylinder 4 downward through the traction connection mechanism 9 connected to it, and then drives the internal pushing part 5, filter plate 6 and centrifugal turning mechanism 7 to settle as a whole, until the plate rack 51 on the outside of the bottom of the separation cylinder 4 is embedded in the receiving groove of the intermittent lifting platform 32, the water level overflows the holes in the side wall of the separation cylinder 4, and the water in the bottom cavity (cleaning cabin) of the chassis 1 flows in through the holes in the side wall and bottom wall of the separation cylinder 4 and fully contacts the chestnut; the plate rack 51 contacts the transmission part 3 and activates the double cleaning mechanism: the driving device drives the multi-stage transmission shaft 8 to rotate coaxially with the rotating transmission part 31 through the coupling, and with the help of the inclined section and longitudinal sliding design of the bottom of the intermittent lifting platform 32, the lifting drive wheel 312 periodically lifts / releases the intermittent lifting platform 32 when it moves circumferentially around the multi-stage transmission shaft 8, so that the delivery The pushing part 5 can carry the filter plate 6 at its top to oscillate up and down in the separation cylinder 4, so that the silt falling off the surface of the chestnuts can be accelerated to pass through the filter plate 6; further, when the filter plate 6 is lifted or lowered, it pushes the inner grid lining plate 72 and the outer grid sleeve plate 71 to shrink / expand in a nested manner, so that the grid openings of the two can be intermittently aligned, and combined with the rotation of the inner grid lining plate 72 with the multi-stage transmission shaft 8, the inner grid lining plate 72 drives the outer grid sleeve plate 71 to make circumferential displacement along the inner annular groove of the inner wall of the separation cylinder 4, and the chestnuts can be turned over by alternately opening and closing the grid openings, forming a coordinated cleaning of longitudinal oscillation and circumferential flipping, which significantly improves the cleaning efficiency and effect of the chestnuts; during the up and down oscillating movement of the recursive pushing part 5, the insertion plug 52 continuously penetrates the holes in the bottom wall of the separation cylinder 4 for dynamic dredging, effectively preventing the holes at the bottom from being blocked by silt deposition; After the chestnuts are cleaned, the equipment switches from the cleaning mode to the draining mode. The traction device pulls the separation cylinder 4 upward through the traction connection mechanism 9 connected to it, and then drives the internal recursive part 5, filter plate 6 and centrifugal turning mechanism 7 to rise as a whole. The plate frame 51 is separated from the receiving groove of the intermittent lifting platform 32, and the separation cylinder 4 gradually leaves the water and drains the water through the holes until it completely enters the draining chamber, that is, the discharge port on the side wall of the separation cylinder 4 is coplanar with the draining guide part 10; the recursive part 5 and the filter plate 6 fall freely due to the loss of the support of the intermittent lifting platform 32 until the support handle of the support rod 522 is stuck above the hole in the bottom wall of the separation cylinder 4, realizing the recursive part. The pusher 5, the filter plate 6 and the inner grid lining plate 72 are stably suspended. Since the inner shaft section 83 is connected to the inner grid lining plate 72, the multi-stage transmission shaft 8 can be extended to its maximum length as the separation drum 4 is lifted. The inner grid lining plate 72 is pulled away from the outer grid sleeve 71 and fits on the surface of the filter plate 6. At this time, the grid openings between the inner grid lining plate 72 and the outer grid sleeve 71 are offset and closed. At the same time, the outer grid sleeve 71 and the inner grid lining plate 72 keep rotating circumferentially around the multi-stage transmission shaft 8. The centrifugal turning mechanism 7 in the closed state implements centrifugal dehydration on the chestnuts in the separation drum 4, prompting the residual moisture to be efficiently discharged through the holes on the side wall of the separation drum 4. After the draining is completed, the equipment switches to the unloading mode. The operator opens the operating window on the side wall of the chassis 1 and pushes the adjusting handle 113 circumferentially, driving the rotating ring 111 to move along the outer ring groove of the separation drum 4, so that the arc gate 112 is separated from the discharge port of the separation drum 4; then the intercepting plate 103 is pushed up to open the passage between the collecting ring pipe 101 and the discharge port, and locked in position by the lock 104; at this time, the outer grid sleeve 71 and the inner grid lining plate 72 continue to rotate around the multi-stage transmission shaft 8, and the closed centrifugal turning mechanism 7 implements centrifugal unloading of the chestnuts on the surface of the filter plate 6. Under the action of centrifugal force, the chestnuts pass through the discharge port, the collecting ring pipe 101 and the radial tube 102 in sequence to complete the automatic discharge; After completing the current batch processing, reset the various components of the equipment to their initial state and start a new round of chestnut processing cycle.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, these should be included under the protection of the present invention.
