Description

Freezing plant

Affiliated technical field:

The present invention relates to a kind of freezing equipment, particularly a kind of net belt type freezing plant.

Background technology:

Existing multisection type circulation mesh-belt conveying is frozen in the freezing plant of product, the working face of the modular pectination member of foraminous conveyer is a plane, the guipure straight line is carried when being frozen product, the big plane that the working face of guipure is made up of the facet of many modular pectination members, when guipure runs to around driven wheel, the working face of guipure just is converted into the polygon curved surface, and the size change can appear in the spacing of this curved surface and material scraping plate cutting edge, causes the unclean phenomenon of scraper; In addition, the modular plastic pectination member Abherent of existing guipure is relatively poor, the quilt that contains moisture content for solution freezes product and the guipure that directly returns feeding mechanism and be in solidification point once contacting the problem of adhesion, the circulation guipure is behind material scraping plate, often to extend outside the body of thermal insulating box, blow or hot water drenches and to make guipure go back up to normal temperature through hot blast, blow away again and be recycled to charging aperture behind the moisture content on the guipure and accept and frozen product, like this, not only guipure is long, and structure is complicated, materials are many, the cost height, volume is bigger, operational reliability is influenced, and big energy-consuming when using, and production cost increases.

Summary of the invention:

The objective of the invention is: the technical scheme that a kind of freezing plant is provided, when the circulation foraminous conveyer of this device runs to around driven wheel, the working face of guipure is a convex arc surface shape, the spacing of this working face and material scraping plate cutting edge is constant, scraper is clean, and the circulation foraminous conveyer directly returns feeding mechanism and accepts and frozen product and be difficult for bonding.

Technical scheme of the present invention is: freezing plant comprises body of thermal insulating box, place body of thermal insulating box to advance respectively, the feeding mechanism of discharging opening and discharging mechanism, be contained at least two sections circulation foraminous conveyers in the body of thermal insulating box, be positioned at the evaporimeter of body of thermal insulating box and the air-cooler that the blower fan group constitutes, be loaded on the material scraping plate at circulation foraminous conveyer live axle place, the air outlet of air-cooler communicates with the wind centralizing cavity of circulation foraminous conveyer below, the feed pipe of evaporimeter links to each other with refrigeration unit respectively with muffler, live axle links to each other with electric reducer and drives guipure by live axle, first section circulation foraminous conveyer mainly flexibly connected by dome arc working face shape modular polytetrafluoroethylene (PTFE) or poly-perfluoro second propylene pectination member and bearing pin and forms, the arc surface radius of the dome arc working face of this member is complementary with the radius that is contained in the driven wheel on the live axle, when making the circulation foraminous conveyer around driven wheel, the working face of guipure becomes an arc surface, guarantee that this arc surface and material scraping plate cutting edge spacing are constant all the time, the outside, width both sides of circulation foraminous conveyer working face is respectively equipped with a grade material wall.The inner end plate and the outer end plate of fixedlying connected with bearing pin that flexibly connect with bearing pin are arranged respectively on the bearing pin of circulation foraminous conveyer face width direction both sides.Feeding mechanism can be known feed hopper or feeding rack.Polytetrafluoroethylene (PTFE) is called for short PTFE or F4, and molecular formula is:

Poly-perfluoro second propylene is called for short FEP or F-46, and molecular formula is:

The dome arc working face shape modular polytetrafluoroethylene (PTFE) or the poly-perfluoro second propylene pectination member back side are concave curved surface shapes.Also have air-permeating hole on the dome arc working face of this member,, saved expensive polytetrafluoroethylene (PTFE) or poly-perfluoro second propylene simultaneously so that increase ventilative property and refrigerating effect.

For improving wearability and intensity, on dome arc working face shape modular pectination member and the bearing pin that dome arc working face shape modular pectination member is connected force-bearing ring is housed also, the peripheral radius of force-bearing ring is identical with the peripheral radius in dome arc working face shape modular pectination member upper pin hole, and the most of thrust of the flank of tooth of driven wheel passes to bearing pin in force-bearing ring.Also be connected with the tension stress sheet on the bearing pin, tension stress when being used for loading greatly, the convex arc surface of tension stress sheet is lower than the dome arc working face of modular pectination member on the guipure that installs, to prevent to be frozen product directly contact and bonding.

Major advantage of the present invention is: when the circulation foraminous conveyer ran to driven wheel, the working face of guipure was a convex arc surface shape, and this working face and material scraping plate cutting edge spacing are constant, and scraper is clean; The circulation foraminous conveyer directly returns feeding mechanism and accepts and frozen product and not bonding; Structure is simpler, and materials are few, and manufacturing cost is lower, and volume is less, moves more reliably, uses energy consumption low, helps reducing use cost.
