Description

Technical Field

[0001] The utility model belongs to the technical field of casing production, and specifically relates to a one-to-two production system for collagen casings. Background Art

[0002] In the collagen casing production line, a one-to-one production method is often adopted, that is, a set of casing raw material supply device is produced through an extruder in conjunction with a casing forming machine and a casing drying line. The equipment occupies a large space, but the production energy efficiency is low.

[0003] At the same time, when producing collagen casings, various collagen casing manufacturers use traditional extruders to transport raw materials from the casing raw material supply device to the casing forming machine. Because the traditional extruder has two extrusion cylinders, during continuous production, the reversal of the extrusion cylinders can easily lead to unstable raw material extrusion pressure, resulting in uneven feeding of the casing forming machine, and the casings produced have bulging caliber or thin waist. The casing quality is unstable, which seriously affects the casing quality.

[0004] Furthermore, due to the existence of the extruder, in order to ensure the stability of the casing quality as much as possible, a raw material supply device is often selected for use with an extruder. If the production scale is to be expanded, only simple equipment stacking and purchase of multiple raw material supply devices and extruders can be performed, which makes it difficult to achieve a one-to-many production of collagen casings.

[0027] The core of the utility model is to provide a one-to-two production system for collagen casings, which continuously and stably transports the material in the storage cylinder to the casing forming machine through a screw pump to improve the quality of the casings. In addition, one storage cylinder can be equipped with multiple screw pumps at the same time, which then correspond to multiple casing forming machines and multiple casing drying lines, thereby realizing one-to-two or one-to-multiple production of collagen casings and improving production efficiency.

[0028] In order to enable those skilled in the art to more clearly understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with specific embodiments.

[0029] Figure 1 This is a structural schematic diagram of the one-to-two production system for collagen casings provided by the utility model, in which the material moves in the direction indicated by the arrow; the system includes a collagen casing raw material supply device, a screw pump, a molding device, a drying device and other structures, and each structure is located on a pipeline for continuously conveying materials.

[0030] The collagen casing raw material supply device is used for crushing and storing collagen casing raw materials. The collagen casing raw material supply device comprises a feeding hopper 1, a primary spiral crusher 2, a secondary spiral crusher 3, a hydraulic extrusion cylinder 4, a primary filter 5 and a storage cylinder 6 which are connected in sequence.

[0031] The feeding hopper 1 is a trumpet-shaped structure with an upward opening, which is used to collect raw materials and transfer them to the primary spiral crusher 2. Figure 1 As shown, the feeding hopper 1 is arranged directly above the primary spiral crusher 2, the discharge port of the feeding hopper 1 is connected to the feed port of the primary spiral crusher 2, and the discharge port of the feeding hopper 1 is arranged above the feed port of the primary spiral crusher 2, so that the material can enter the primary spiral crusher 2 by gravity, saving energy.

[0032] It can be understood that in order to avoid pipeline blockage, the discharge port of the feeding hopper 1 is arranged directly above the feed port of the primary spiral crusher 2.

[0033] The primary spiral pulverizer 2 is used for preliminary pulverization of the raw material, and is arranged directly below the feeding hopper 1. The secondary spiral pulverizer 3 is used for further pulverizing the raw material to meet the production requirements of collagen casings. The feed port of the secondary spiral pulverizer 3 is connected to the discharge port of the primary spiral pulverizer 2, and the feed port of the secondary spiral pulverizer 3 is arranged below the discharge port of the primary spiral pulverizer 2.

[0034] It can be understood that in order to avoid clogging of the crushed material in the pipeline, the material inlet of the secondary spiral crusher 3 can be set directly below the discharge port of the primary spiral crusher 2, so that the raw materials in the primary spiral crusher 2 can directly enter the secondary spiral crusher 3 by gravity.

[0035] The working principle of the spiral pulverizer is to use high-speed rotating parts (such as hammer heads, spiral knife groups, etc.) to strike, rub and impact the materials, thereby crushing the materials. The materials are subjected to extrusion, friction and impact forces in the crushing chamber, resulting in a crushing effect. The utility model uses a spiral pulverizer to crush the raw materials, and by setting a two-stage spiral pulverizer, it is ensured that the particle size of the obtained material meets the requirements for the preparation of collagen casings.

[0036] The feed port of the hydraulic extrusion cylinder 4 is connected to the discharge port of the secondary spiral crusher 3. The hydraulic extrusion cylinder 4 is used to transfer the material crushed by the secondary spiral crusher 3 to the primary filter 5 for filtration. The hydraulic extrusion cylinder 4 transfers the material through reciprocating motion. Figure 1 As shown, two hydraulic squeeze cylinders 4 may be provided.

[0037] It can be understood that in order to increase the transmission rate, a plurality of hydraulic extrusion cylinders 4 can be provided.

[0038] The primary filter 5 is used to filter the crushed material and timely screen out the material with particle size that does not meet the requirements to avoid affecting the quality of the obtained collagen casing. The discharge port of the hydraulic extrusion cylinder 4 is directly connected to the primary filter 5. The material with particle size that meets the requirements filtered out by the primary filter 5 enters the storage cylinder 6 for storage, and the filtered material with particle size that does not meet the requirements is returned to the feeding hopper 1 and re-enters the spiral crusher for crushing until the particle size meets the requirements, thereby avoiding waste of materials.

[0039] Among them, the mesh size of the first-level filter is 0.09~0.11mm.

[0040] It can be understood that the primary filter 5 can be arranged just above the feed port of the storage cylinder 6, and the filtered material directly enters the storage cylinder 6 for storage by gravity. The primary filter 5 can also be arranged on one side of the storage cylinder 6, and the filtered material is pumped into the storage cylinder 6 by a pump and a pipeline.

[0041] The feed port of the screw pump 7 is connected to the discharge port of the storage cylinder 6. The screw pump 7 is used to continuously and stably transport the material stored in the storage cylinder 6 to the secondary filter 8. The working principle of the screw pump is mainly based on the working mode of the volumetric rotor pump. The material is transported or pressurized by the volume change between the pump body and the screw. The core working process of the screw pump is the formation, displacement and disappearance of the sealed cavity. When the material enters the screw pump, the screw rotates at a constant speed driven by the motor, and a sealed cavity is formed between the screw and the bushing. With each rotation of the screw, this sealed cavity is pushed from the inlet to the outlet, so that the material flows evenly along the axial direction. The screw pump has low vibration and no pulsation during operation, and can be transported in the reverse direction.

[0042] The utility model utilizes a screw pump 7 to replace an old extruder for material transmission, and material flow control can be achieved by controlling the rotation speed of the screw pump 7. Since the screw pump 7 is in continuous operation, there is no cylinder change situation of the old extruder, so the material pressure and flow reaching the casing forming machine can be stably controlled.

[0043] It can be understood that the screw pump 7 takes up little space and can easily realize the production of collagen casings in a one-to-two or one-to-many manner. Figure 1 As shown, there are two screw pumps 7, the feed ports of the two screw pumps 7 are connected to the storage cylinder 6, and the discharge ports of the two screw pumps 7 are respectively connected to a molding device, forming two production lines, realizing one-to-two production of collagen casings.

[0044] One storage tank 6 can be equipped with multiple screw pumps 7 at the same time, which then correspond to multiple forming devices and multiple drying lines, so as to realize one-to-many production of collagen casings and reduce equipment investment.

[0045] The forming device is used to receive the material delivered by the screw pump 7 and form it to obtain a wet casing. The forming device is an existing casing forming device, and a casing forming machine 9 can be used. The feed inlet of the casing forming machine 9 is connected to the discharge outlet of the screw pump 7.

[0046] On the basis of the above scheme, the one-to-two production system of collagen casings provided by the utility model also includes a secondary filter 8. The secondary filter 8 is used to filter the crushed material again, and timely filter out the materials that are aggregated and impurities and other materials whose particle sizes do not meet the requirements, so as to avoid affecting the quality of the obtained collagen casings. The secondary filter 8 is arranged between the screw pump 7 and the casing forming machine 9. The discharge port of the screw pump 7 is directly connected to the secondary filter 8. The materials with particle sizes that meet the requirements filtered out by the secondary filter 8 enter the casing forming machine 9 through the feed port of the casing forming machine 9 for forming processing. The filtered materials with particle sizes that do not meet the requirements are returned to the feeding hopper 1 and re-entered into the spiral crusher for crushing until the particle size meets the requirements, thereby avoiding waste of materials.

[0047] Among them, the mesh number of the secondary filter 8 is 0.11-0.13 mm.

[0048] The drying device is a casing drying line 10, which is used to dry the casing produced by the casing forming machine 9. There are many types of casing drying lines 10 at present. The casing drying line 10 described in the utility model can use existing drying equipment, such as the dryer disclosed in the patent "CN205321056U A one-to-four device for producing collagen casings". The discharge port of the casing forming machine 9 is connected to the feed port of the casing drying line 10, and the casings are arranged in sequence on the casing drying line 10 for drying.

[0049] Power pumps for driving materials can be respectively provided on the output pipelines of the primary spiral pulverizer 2, the secondary spiral pulverizer 3, the hydraulic extrusion cylinder 4, the storage cylinder 6, the screw pump 7, and the casing forming machine 9, and each power pump is respectively connected to a DCS (Distributed Control System) control system; the rotation speed of the screw pump 7 can also be controlled on and off by the DCS control system to realize continuous production.

[0050] The utility model realizes the continuous production of one-to-two or one-to-many collagen casings through the mutual cooperation of various equipment such as a primary spiral pulverizer 2, a secondary spiral pulverizer 3, a hydraulic extrusion cylinder 4, a storage cylinder 6, a screw pump 7, and a casing forming machine 9, and realizes automatic control by a DCS control system; since the screw pump 7 is used to transport materials, since the screw pump is in continuous operation, there is no need to change the cylinder of the old extruder, and the material pressure and flow reaching the casing forming machine can be stably controlled, the problem of uneven caliber of the collagen casings is solved, the quality of the obtained collagen casings is guaranteed to be stable, and the casing quality is improved.

[0051] The utility model provides a specific embodiment for illustration:

[0052] Combination Figure 1As shown, the raw materials for preparing collagen casings in the feeding hopper 1 enter the primary spiral pulverizer 2 for preliminary pulverization, and the materials after preliminary pulverization enter the secondary spiral pulverizer 3 for further pulverization, and the pulverized materials are transported to the primary filter screen 5 through the hydraulic extrusion cylinder 4, and the filtered materials are stored in the storage cylinder 6. The filtered materials are returned to the feeding hopper 1 and enter the pulverizer again for pulverization.

[0053] The material in the storage cylinder 6 is transported to the secondary filter 8 by one or more screw pumps 7, and the filtered material enters the casing forming machine 9 to be formed into casings, and the obtained casings enter the casing drying line 10 for drying.

[0054] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
