Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of device for crushing granule squeezing, and specifically relates to a kind of device for crushing granule squeezing. BACKGROUND

[0002] After ultrafine crushing, the coconut meat used for making coconut original pulp carries about 10%~15% larger particles in the coconut original pulp solution formed, so after filtering the coconut original pulp through filter screen, the larger particles are screened out, and the larger particles are put into the squeezing device for the last squeezing, so as to fully improve the utilization rate of coconut meat.

[0003] The current squeezing device basically adopts double-roller rolling method, after crushing particles are put in, the crushing particle groups are extruded by the narrow gap between the double rollers, and the inventors found in actual production process that although the coconut meat particles after ultrafine crushing do not meet the particle size requirements of coconut original pulp (coarse particles will affect taste, so need to be filtered out), but the particle size of the coconut meat particles is also small, and the squeezing gap of the general double-roller squeezing mechanism is designed for coarse coconut meat particles, and the crushing particles can be used after gathering into groups, but if the filtered crushing particles obtained after ultrafine crushing are directly put into the double-roller squeezing mechanism, part of the crushing particles will directly pass through the squeezing gap of the double-roller squeezing mechanism before gathering into groups, so that the utilization rate of coconut raw materials is reduced.

[0004] Therefore, a device for crushing granule squeezing is designed, which can gather into groups before entering the double-roller squeezing mechanism, and then cooperate with the double-roller squeezing mechanism for squeezing, so as to improve the utilization rate of coconut meat. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of device for crushing granule squeezing to solve the problems described in the background art.

[0006] The technical scheme of the utility model is realized as follows:

[0007] The utility model provides a kind of device for crushing granular squeeze, including double-roller squeezing mechanism, the upper end of double-roller squeezing mechanism is equipped with feed inlet, the lower end of double-roller squeezing mechanism is equipped with discharge port, the bottom of double-roller squeezing mechanism is equipped with obliquely arranged inclined filter screen, filter screen bottom is equipped with liquid collecting tank, the upper of the double-roller squeezing mechanism is also equipped with transversely arranged extrusion cylinder, the rear end of extrusion cylinder is closed, the inside of extrusion cylinder is cylindrical bin, the middle part of the lower end surface of extrusion cylinder is upwardly provided with the discharge port being communicated with bin, the bin behind discharge port is air bin, the bin in front of discharge port is extrusion bin, front baffle ring and rear baffle ring are further fixed on the bin wall of air bin, front baffle ring is spaced apart and located in front of rear baffle ring, front piston and rear piston are further provided in air bin, front piston is located in front of front baffle ring, rear piston is located in rear of rear baffle ring, front piston and rear piston are further fixedly connected by connecting rod, front piston and rear piston are all sealingly and slidably connected with the bin wall of air bin, pressure regulating and pressure relief valve and inflation one-way valve, which are communicated with air bin, are further provided on the rear end wall of extrusion cylinder, inflation pump is further provided outside extrusion cylinder, inflation pump is further connected with inflation one-way valve by gas delivery pipe, feed hopper is further provided on the top of extrusion bin, extrusion piston is further provided in extrusion cylinder, extrusion piston is sealingly and slidably connected with the bin wall of extrusion bin, mounting plate is further provided on the front end of extrusion cylinder, telescopic push rod is further fixed on mounting plate, the telescopic rod of telescopic push rod is extended into extrusion bin and connected with extrusion piston, the discharge port is located directly above the feed inlet of double-roller squeezing mechanism.

[0008] When using the above scheme, the crushed particles are put into the extrusion bin of the extrusion cylinder from the feed hopper, and the crushed particles form a loose particle pile in the extrusion bin. Then the telescopic push rod is started, and the telescopic rod of the telescopic push rod is extended backward to push the extrusion piston to move towards the rear end of the extrusion bin, and the extrusion piston pushes the loose particle pile to move towards the front piston until it abuts against the front piston.

[0009] By setting the pressure relief pressure of the pressure regulating and pressure relief valve, the pressure required for the rear movement of the front piston can be controlled. As the extrusion piston continuously extrudes the front piston, the loose particle pile is gradually extruded into a cylindrical compact particle pile in this process.

[0010] When the transmission force of the extrusion piston to the front piston through the particle pile is greater than the pressure required for the rear movement of the piston, the front piston moves backward, and the front piston pushes the rear piston to move backward through the connecting rod, and the rear piston extrudes the air in the air bin, and the air in the air bin is discharged from the air bin through the pressure regulating and pressure relief valve, so that the volume of the air bin is reduced, and the front piston and the rear piston move backward as a whole.

[0011] By setting the telescopic rod of the telescopic push rod to extend the stroke, the particle pile is pushed to the top of the discharge port, and the telescopic rod is just stopped extending. Then the telescopic rod is controlled to retract forward, driving the extrusion piston to retract to the front end. After the particle pile loses the clamping force of the extrusion piston and the front piston, it falls downward from the discharge port under the action of gravity and enters the double-roller pressing mechanism. When the particle pile is discharged from the extrusion cylinder, the air charging pump is started to charge air into the air chamber, pushing the rear piston to move forward, so that the front piston returns to the extrusion chamber.

[0012] After the compact cylindrical particle pile enters the double-roller pressing mechanism, loose crushed particles can be prevented from directly passing through the pressing gap of the double-roller pressing mechanism. The double-roller pressing mechanism presses the particle pile, and the coconut milk drops downward through the inclined filter screen into the liquid collecting tank, while the waste residue is intercepted by the inclined filter screen and discharged.

[0013] By setting the rear retaining ring, the movement distance of the rear piston can be effectively limited, so that the front piston can move to the preset position when it is reset. By setting the front retaining ring, the movement distance of the front piston can be effectively limited to prevent the front piston from moving backward excessively.

[0014] Further technical solutions are that the double-roller pressing mechanism includes a third support and a pressing box arranged on the third support. The feeding port is arranged at the top of the pressing box, and the discharging port is arranged at the bottom of the pressing box. The inside of the pressing box is further provided with two opposite rotating rollers. Two rotating shafts are respectively arranged on the central axes of the two rotating rollers. The two ends of the rotating shafts are respectively rotatably arranged in the opposite side walls of the pressing box. One end of the rotating shafts further penetrates the side wall of the pressing box. The part of one rotating shaft penetrating the side wall of the pressing box is further fixedly provided with a driving gear. The part of the other rotating shaft penetrating the side wall of the pressing box is further fixedly provided with a driven gear. The driving gear and the driven gear are in meshing connection. A motor is further fixedly arranged on the outer wall of the pressing box. A driving gear is fixedly arranged on the output shaft of the motor. The driving gear and the driving gear are in meshing connection.

[0015] When the above scheme is used, the motor drives the driving gear to rotate, the driving gear drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, so that the driving gear and the driven gear rotate towards each other. The driving gear and the driven gear drive the two rotating shafts to rotate towards each other, and the two rotating shafts drive the two rotating rollers to rotate towards each other, thereby pressing the particle pile.

[0016] Further technical solutions are that two upper guide plates are further oppositely arranged in the pressing box. The upper guide plates are arranged above the rotating rollers. The two upper guide plates are clamped to form an upper guide channel. The upper guide channel is arranged directly below the discharging port. The upper guide channel is arranged directly above the pressing gap between the two rotating rollers.

[0017] When the above scheme is used, the upper guide channel is formed by arranging the upper guide plates, which can effectively guide the particle pile to the middle of the two rotating rollers, thereby effectively pressing the particle pile.

[0018] Further, the technical scheme is that two lower material guide plates are oppositely arranged in the squeezing box, the lower material guide plates are arranged below the rotating roller, and a lower material guide channel is formed by clamping the two lower material guide plates, and the lower material guide channel is arranged above the middle part of the inclined filter screen.

[0019] When the above scheme is used, the lower material guide channel formed by the lower material guide plates can effectively guide the coconut raw pulp into the liquid collecting tank and effectively guide the waste residues into the middle part of the inclined filter screen.

[0020] Further, the technical scheme is that a plurality of cutting knives are arranged between the two upper material guide plates, the two ends of the cutting knives are fixedly connected to the upper material guide plates, the cutting knives are arranged in parallel and are spaced apart, and the cutting knives are arranged directly below the discharging port.

[0021] When the above scheme is used, the cutting knives can divide the particle pile into smaller blocks, facilitating the rapid extrusion of the rotating roller.

[0022] Further, the technical scheme is that the telescopic push rod is an electric push rod.

[0023] Further, the technical scheme is that the first support is arranged on the telescopic push rod.

[0024] Further, the technical scheme is that the second support is arranged on the mounting plate.

[0025] Further, the technical scheme is that the fourth support is arranged on the inclined filter screen.

[0026] Further, the technical scheme is that when the rear piston abuts against the rear retaining ring, the front piston is arranged in the extrusion chamber.

[0027] The beneficial effects of the utility model lie in:

[0028] 1. Preventing the crushed particles from directly passing through the double-roller gap: through the design of the telescopic push rod and the extrusion piston, the crushed particles are pre-pressed to form a compact cylindrical particle pile, which can prevent the loose crushed particles from directly passing through the pressing gap of the double-roller pressing mechanism, thereby improving the utilization rate of coconut meat pressing.

[0029] 2. Controllable pressure: through the arrangement of the pressure regulating and releasing valve, the pressure required for the rear movement of the front piston can be accurately controlled, thereby adjusting the extrusion process and ensuring the extrusion effect.

[0030] 3. Accurate reset: through the arrangement of the front retaining ring and the rear retaining ring, the movement distance of the front piston and the rear piston is effectively limited, so that the front piston can be moved to the preset position when resetting, thereby improving the stability and reliability of the equipment.
