Abstract

The present invention discloses a grinding machine in which the grinding unit is distributed in a plane spiral. In addition, the grinding platform uses an extendable design, so that when grinding, when it encounters harder particles, it automatically moves out of the way without crushing them or getting stuck. Then, these harder particles are gradually removed from the grinding wheel through the spiral distribution of the grinding unit. However, because the uncrushed particles cannot pass through the grinding plate, they are swept away by the action of the brush and fall into the residue discharge groove. This achieves "soft grinding without hard grinding", not only effectively protecting the grinding machine from damage, but also effectively removing large particles of hard impurities in the porridge, thereby improving the quality of the following food.

Description

A type of dough mill

Technical area

The present invention relates to kitchen waste treatment technology, and more particularly to a type of dough mill.

Background technology

In the process of converting food waste into animal feed, it is necessary to crush and grind these wastes. Since food waste may contain some harder materials such as wood, ceramics, iron pieces, stones, glass, bones, etc., introducing these hard materials into the dough mill may cause damage. Additionally, if they mix with the dough and undergo fermentation to become animal feed, they can affect the health of animals fed with them. Therefore, how to effectively remove these hard objects from food waste in the grinding process is a problem to be solved. It could also significantly improve the current process of transforming food waste into animal feed and the final quality of that feed.

Content of the invention

Considering the shortcomings of current technology, the technical problem to be solved by the present invention is to provide a dough mill capable of effectively removing hard objects contained in food waste.

To achieve this objective, the present invention provides a dough mill comprising a grinding shell, a grinding hole plate installed inside the grinding shell. A grinding disc is mounted on the grinding hole plate, with grinding projections. The grinding hole plate is equipped with through holes for the passage of the paste and a residue evacuation groove, the latter being in communication with one end of a discharge pipe.

An external grinding cylinder is mounted on the grinding disc, with through grooves for the paste outlet. Inside the outer grinding cylinder, an inner grinding cylinder is mounted so as to rotate circularly. This internal cylinder contains a grind wheel on which are arranged several grind mounting holes in a planar spiral. The grinding wheel is operated by external force.

Each grind mounting hole contains a grind unit, consisting of an outer grind cylinder and a grind platform that cooperates with the grind protrusions. The grinding platform is mounted on one end of a grinding piston, the other end of the piston being inserted into a hole in the outer grinding cylinder and slidably mounted therein. This hole is located inside the outer grinding cylinder. The end of the grinding piston inserted into the hole of the outer cylinder is assembled with one end of a grinding shaft. The other end of this axis, after being inserted into a grinding spring, passes through an internal grinding ring and is slidably mounted there. The grind spring exerts a force on the grind piston, pulling it away from the internal grind ring. This internal grinding ring is mounted inside the external grinding cylinder.

The advantages of the present invention are as follows:

The grinding unit of this invention uses a planar spiral distribution, and the grinding platform is designed to be expandable. So, when grinding, when faced with harder particles, it will automatically retract without crushing them or getting stuck. Then these harder particles will be gradually discharged from the grinding wheel through the spiral distribution of the grinding unit. However, because these ungrinded particles cannot pass through the grinding hole plate, they will be swept away under the action of sweeping to fall into the residue discharge groove. This results in a grind that crushes the soft elements without affecting the hard elements. Not only does this effectively prevent damage to the dough mill, but also effectively removes large particles of hard impurities in the dough, thereby improving the quality of the next feed.

Specific embodiment

The following description will be made with reference to the figures of the exemplary embodiment of the present invention, in order to clearly and completely describe the technical solution of this exemplary embodiment.

Referring to Figures 1 to 10, the dough mill of this embodiment comprises a grinding shell 110, a grinding base 120 and a grinding hole plate 130.

The grinding base 120 and the grinding hole plate 130 are both installed inside the grinding shell 110. The grinding base 120 is equipped with a conical convergence groove 121, the lower part of which is made of communication with one end of the paste outlet pipe 170. A grinding disc 140 is mounted on the grinding hole plate 130, and the grinding disc 140 is equipped with a diversion cone 141 and grinding protrusions 142.

Through holes for the passage of paste 131 and a residue evacuation groove 132 are provided on the grinding hole plate 130. Two protruding diversion blocks 133 are arranged on either side of the evacuation groove residue 132, and the upper surface of the protruding blocks 133 is higher than the upper surface of the grinding hole plate 130. The residue discharge groove 132 is communicated with one end of the residue discharge pipe 720 . A

External grinding cylinder 210 is mounted on the grinding disc 140, and the external grinding cylinder 210 has through grooves for dough outlet 211. After grinding, the food waste is discharged through the grooves 211 to the upper part of the grinding hole plate 130. Inside the outer grinding cylinder 210, an inner grinding cylinder 220 is mounted so as to rotate circularly. A grinding wheel 240 is mounted inside the internal grinding cylinder 220. A plurality of grinding mounting holes 241 are arranged on the grinding wheel 240 in a planar spiral. A grind inlet hole 242 is also provided on the grind wheel 240. The diversion cone 141 is inserted into the grind inlet hole 242 in order to guide and distribute the waste entering the inlet hole of grinding 242 towards the grinding wheel 240 around the diversion cone 141.

The internal grinding cylinder 220 is equipped respectively with a first internal ring 221 and a second internal ring 222. The first internal ring 221 is assembled with a brush cylinder 230, on which a brush support 231 is mounted. 232 is mounted on the brush holder 231 and is close to the face of the grinding hole plate 130 for brushing the paste which is slightly thicker (5-10 millimeters) thereon. A brush face bearing 920 is mounted in the groove between the first inner ring 221 and the brush cylinder 230, the backing ring of which is pressed against the face of the outer grinding cylinder 210, thereby allowing the first inner ring 221 to rotate circularly with the external grinding cylinder 210.

The part of the internal grinding cylinder 220 located between the first grinding separation ring 111 and the second internal ring 222 is equipped with a grinding ring gear 530. This grinding ring gear 530 engages and is driven by a gear grinding intermediate 541, which is itself driven by a grinding motor gear 542 mounted on the output shaft of the grinding motor 910. The grinding motor 910 is mounted on the second grinding separation ring 112, and the first and second grind separation rings 111 and 112 are both mounted on the grind shell 110.

The second internal ring 222 is assembled at one end of the grinding screw 410, the other end of which passes successively through the grinding compression ring 522 and the grinding weight block 510. The grinding compression ring 522 is mounted on the grinding pressure block 521, together forming the compression block 520. The grinding pressure block 521 is inserted into the outer grinding cylinder 210 and is slidably mounted therein. A pressure bag 250, which is elastic and has an internal cavity 251, is mounted between the grinding wheel 240 and the grinding pressure block 521. On the pressure bag 250, a pressure pipe head 252 is mounted and inserted into one end of the grinding mounting hole 241 to be assembled there in a watertight manner.

In the grinding mounting hole 241, from top to bottom, a limiting ring for the pipe head 246, a separation ring 243 and a grinding limiting ring 244 are successively mounted. First seals 245 and second 247 are respectively mounted on the two upper and lower faces of the grinding limitation ring 244. The separation ring 243 is assembled in a sliding manner on the sealing axis 810, one end of which is close to the ring grinding limitation 244 is equipped with a sealing ring 820. A sealing spring 830 is mounted on the part of the sealing axis 810 located between the separation ring 243 and the sealing ring 820, this spring exerting on the sealing ring 820 a force pressing it against the first seal 245 to obtain a seal between the sealing ring 820 and the grinding limitation ring 244 in the state initial.

Each grind mounting hole 241 contains a grind unit 300, which includes an outer grind cylinder 310 and a grind platform 342. This platform is mounted at one end of the grind piston 341, the other end of which is inserted by sliding manner in the hole of the external cylinder 311, located in the external grinding cylinder 310. One end of the grinding piston 341 is mounted on a grinding axis 340, the other end of which, after being inserted into a grinding spring 350, passes through an internal grinding ring 313. This spring exerts a force on the grinding piston 341, pushing it away from the internal ring 313. This internal grinding ring 313 is mounted inside the external cylinder of grinding 310. One end of the hole of the outer cylinder 311, close to the grinding limiting ring 244, is equipped with a grinding cap 320. This cap has a guide hole 321 and is equipped with a guide pipe 330. The face of the grinding cap 320 is pressed against the second seal 247, and at this time the guide pipe 330 pushes the seal ring 820 towards the separation ring 243, thereby canceling the sealing between the sealing ring 820 and the grinding limitation ring 244.

Pressurized water is then introduced from the pressure compartment 251 into the hole of the outer cylinder 311. The outer grind cylinder 310 has an external thread and the grind mounting hole 241 has an internal thread, thereby allowing the assembly of the external grind cylinder 310 into grind mounting hole 241 by screwing.

A seal 360 is also mounted on the face of the grinding platform 342 assembled to the grinding piston 341, serving to isolate the faces of the grinding platform 342 and the external grinding cylinder 310 during their movement to the point of movement minimal, in order to avoid excessive wear. In use, the grinding platform 342 cooperates with the grinding projections 142 to grind the food waste and obtain the paste.

The pressurization cavity 251 is connected to one end of the pressurization pipe 253, the other end of the pressurization pipe 253 being connected to the annular pressurization groove 523. This groove is located on the grinding pressure block 520 and is in communication with the pressurization inlet groove 621, located on the pressurization ring 620. The pressurization inlet groove 621 is also connected to one end of the pressurization inlet pipe 610, the other end of which is connected at the outlet of the pressurization valve, the inlet of this valve itself being connected to a source of pressurized water. The pressurization ring 620 is mounted in a sealed manner around the grinding pressure block 520, which can rotate circularly relative to the pressurization ring 620.

The process of using the grinding machine is as follows: 5 S1, The crushed food waste is introduced through the grinding inlet hole 242, and then is distributed around the distribution cone 141 towards the grinding disc 140.

S2, The grinding motor 910 is started, driving the rotation of the grinding motor tooth 542. This tooth, via the intermediate grinding gear 541, drives the circular rotation of the external grinding cylinder 210 (grinding gear ring 530) and therefore, the rotation of the grinding wheel 240. The grinding wheel 240 drives the synchronous rotation of the spirally arranged grinding units 300. The grinding platform 342, in cooperation with the grinding projections 142, grinds the grindable particles into a paste. The hard particles, which cannot be ground, push the grinding platform 342 which compresses the grinding spring 350 and moves towards the hole of the outer cylinder 311, thus allowing the hard particles to pass. Since the grinding units 300 are arranged in a spiral, the hard particles gradually enter the space between two grinding platforms 342, and then are expelled together with the paste through the outlet groove 211 above the hole plate of grinding 130. During the grinding process, water is continuously discharged from the grinding piston 341, preventing debris from returning through the hole of the outer cylinder 311 and adding water to the grinding wheel 240 to cool it and expel the dough.

S3, The paste arriving on the grinding hole plate 130, except for the ungrinded hard particles, will fall through the passing holes 131 into the collecting cone 121. At the same time, the brushing cylinder 230 rotates with the grinding wheel 240, the brush 232 moving the paste along the grinding hole plate 130 to accelerate filtration. The hard, ungrinded particles are pushed by the brush 232 and rotate along the grinding hole plate 130 until they reach the discharge protrusions 133. At this point, the liquid and semi-solid paste will not massively pass through the evacuation protuberances 133, but the hard, uncrushed particles, pushed by the brush 232, will pass through the evacuation protuberances 133, then falling into the evacuation groove 132, to finally be evacuated through the pipe d evacuation 720.

This design effectively protects the grinding disc 142 and the grinding platform 342, preventing hard particles from damaging the grinding disc 142 and the grinding platform 342. It also prevents hard particles from mixing with the paste, thereby affecting the quality of the subsequent fermented fodder. In addition, hard particles can be discharged separately, making its use more convenient.

The water outlet pressure at the grinding installation hole 241 of the platform can be adjusted by changing the weight of the grinding weight block 510, because the weight of this block exerts direct pressure on the grinding bag. pressure 250.
