Description

  The present invention relates to a solid-liquid separation device that separates a liquid and a solid. More specifically, the present invention relates to a solid-liquid separation device that is used for filtering an object to be treated, such as a recovered pickle liquid. It is.

  Products such as ham, sausage and bacon are required to have a uniform taste throughout the product. Therefore, conventionally, using a pickle solution injector, a predetermined amount of pickle solution or seasoning (simply pickle solution) is added to pork, beef, poultry meat chunks (also referred to as “raw wood”), which is the raw material of the product. Sometimes). In the injector, a plurality of injection heads having a large number of injection needles are arranged above the feed conveyor at intervals in the flow direction of the raw wood, and the raw wood conveyed by the feed conveyor is directly below the injection head. When reaching, the conveyor is temporarily stopped and the injection head is lowered to inject the injection needle into the log and inject the pickle liquid.

  Not all of the pickling liquid discharged from the injection head is injected into the log, but there is a considerable amount of pickling liquid that is wasted without being injected. This wasted pickle liquid means that, for example, the injection head starts discharging the pickling liquid almost simultaneously with the operation of the ejector, so that the pickling liquid discharged from the head until the raw wood reaches directly below the head. Liquid and pickle liquid that overflows without being poured into the log.

  Therefore, in order to minimize the waste of the pickling liquid, the pickling liquid that has not been injected into the log is collected and supplied to the injection head again.

  By the way, the recovered pickle liquid (also referred to as “recovered pickle liquid”) includes solids such as fine meat pieces and vacuum bubbles (bubbles) in addition to the pickle liquid. For this reason, the recovered pickle liquid is reused after being filtered by a filtration device (solid-liquid separation device) and subjected to solid-liquid separation.

  The conventional filtration device has a cylindrical filter element and a scraper blade that moves along the surface thereof, and the deposits remaining on the surface of the filter element are scraped off by the scraper blade, and the filtration function is performed during operation. Can be automatically recovered (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 11-2167311

  In the conventional example, the liquid and the solid are separated by filtering the recovered pickle liquid through the filter element. However, since the pressure inside and outside the filter element is substantially equal, the filtering effect is not necessarily good. Further, bubbles in the recovered pickle liquid may pass through the slit hole of the filter element while being deformed by the liquid flow, and may be mixed into the filtered pickle liquid. Therefore, when the filtered pickle liquid is poured into the raw wood, a predetermined amount of the pickle liquid cannot be contained in the raw wood, and a trace of bubbles may be left in the heated product, which may be the subject of claims.

  In view of the above circumstances, an object of the present invention is to enhance the filtration effect and prevent bubbles from being contained in the filtered liquid to be treated.

  This device is provided with a supply port on the upper side and a vertical outer cylinder provided with a solid discharge port on the lower side, and is disposed in the vertical outer cylinder with a flow passage interval and closed at the bottom. In a solid-liquid separator comprising a vertical cylindrical filter element and a liquid discharge pipe connected to the bottom of the filter element, a closing means for closing an upper portion of the filter element, and communicating with the filter element And vacuum suction means for evacuating intermittently.

  The vacuum suction means of the present invention is characterized in that vacuuming is performed once per second. The filter element of the present invention is characterized in that it is a cylindrical body formed by triangular cross-section wires facing each other across a slit hole. The vacuum suction means of the present invention is a vacuum pump, and the vacuum pump is connected to the liquid discharge pipe.

  A liquid storage tank is disposed in the middle of the liquid discharge pipe of the present invention. A guide tube having a head closed and a bottom opened is provided in the middle of the liquid discharge pipe of the present invention, and the bottom is infiltrated into the liquid in the liquid tank.

  Since the present invention is configured as described above, the filtration effect is synergistically performed by the squeezing action and the vacuum suction action by intermittent evacuation, so that the filtration effect can be improved. The flow rate and flow rate of the fluid passing through the slit hole of the filter element are intermittently changed, but the bubbles contained in the liquid to be processed are dragged by the liquid to be processed and forced to the slit hole. And is drawn and drawn by the slit hole. Therefore, the foam is deformed, thinned and broken, and defoamed.

It is a partial cross section front view showing a 1st embodiment of the present invention. It is a principal part expanded sectional view of FIG. It is a partial cross section front view showing a 1st embodiment of the present invention.

A first embodiment of the present invention will be described with reference to FIGS.
The solid-liquid separation device 1 includes an outer cylinder 3 and a filter element 5 built in the outer cylinder 3.

  The outer cylinder 3 is a vertical cylindrical vertical outer cylinder, and is provided with a supply port 3a on the upper side and a funnel-shaped solid discharge port 3b on the lower side. The solid discharge port 3b is connected to a solid discharge pipe 4 with a valve 4a. The upper end of the outer cylinder 3 is closed by a lid 7, and a motor 9 for driving the scraper 11 is fixed on the lid 7.

  The filter element 5 is a member that separates a solid and a liquid, and is concentrically disposed in the outer cylinder 3 with a flow passage interval therebetween. The element 5 engages with a spiral groove formed in the outer periphery of the perforated frame cylinder 6 with the apex apex 5c on the inside while holding the flat bottom surface 5b of the wire 5a having an isosceles cross section on the outside. A slit hole 5c having a desired size is formed between adjacent wires 5a. The size of the slit hole is, for example, 100 to 150 μm, and the size is appropriately selected as necessary.

  A scraper blade 11 of a scraper is provided outside the filter element 5. The scraper blade 11 is rotated by a motor 9 to scrape off the filter residue adhering to the outer peripheral surface of the element 5 to prevent clogging of the slit hole 5c.

  The head and bottom 5d of the filter element 5 are closed, and a liquid discharge pipe 13 is connected to the bottom 5d. A vacuum pump 17 is connected to the liquid discharge pipe 13 via a liquid storage tank 15. The diameter of the liquid discharge pipe 13 is formed so as to allow air to pass above the liquid. This vacuum pump 17 is a vacuum suction means, and is intermittently operated by a control panel (not shown). The vacuum pump 17 is turned on and off at a rate of once per second, for example, and is intermittently driven. The intermittent interval is appropriately selected as necessary. In addition, the upper end of the liquid storage tank 15 is closed so as to be openable and closable by a lid 15a serving as a closing means.

Next, the operation of the embodiment of the present invention will be described.
When the recovered pickle liquid P is discharged from a not-shown pickle liquid injection injector, the recovered pickle liquid P is pumped to the solid-liquid separator 1 through the supply port 3a and swivels in the vertical outer cylinder 3. Then, it flows down and is filtered by the filter element 5.

  Then, the liquid P 1 that has passed through the slit hole 5 c of the filter element 5 flows down in the filter element 5 and is collected in the liquid storage tank 15 through the liquid discharge pipe 13. Further, solids such as fine meat pieces and bubbles P2 that do not pass through the slit hole 5c are collected at the solid discharge port 3b through the flow path interval W and discharged from the solid discharge pipe 4 to the outside.

  The vacuum pump 17 repeats evacuation of the filter element 5 intermittently by the control panel. Therefore, the flow rate and flow rate when the liquid P1 in the recovered pickle liquid P passes through the slit hole 5c are intermittently repeatedly changed. Therefore, the bubbles B contained in the recovered pickle liquid P are deformed B1 while being dragged into the slit holes 5c, and are also broken and lost in contact with the slit holes 5c. P1 can be obtained.

  Further, since the vacuum pump 17 is evacuated, the inside of the filter element 5 can be decompressed, and the suction action can be combined with the throttling action from the filter element 5 to effectively perform the filtering action.

  The scraper blade 11 of the scraper is rotated by the motor 9 and scrapes off the filter residue adhering to the outer peripheral surface of the filter element 5 to prevent clogging of the slit hole 5c.

A second embodiment of the present invention will be described with reference to FIG. 3. The same reference numerals as those in FIGS. 1 and 2 have the same names and functions. The difference between this embodiment and said 1st embodiment is a liquid storage means.
That is, in the first embodiment, the liquid is stored in the liquid storage tank, but in the present embodiment, the liquid is stored in the liquid tank 30 via the guide tube 27 connected to the liquid discharge pipe 13.

The head portion 27a of the guide tube 27 is closed and the bottom portion 27b is open, but the bottom portion 27b is disposed away from the bottom portion of the liquid tank 30, and the liquid in the liquid tank 30 is in operation. P1 enters the guide tube 27, and the bottom 27b is closed by the liquid P1.
In FIG. 3, 31 indicates a strainer, and 33 indicates a liquid feed pipe.

  The embodiment of the present invention is not limited to the above. For example, when vacuuming, a dedicated suction pipe may be separately provided without using the liquid discharge pipe.
