Freezing plant
Technical field:
The present invention relates to a kind of freezing equipment, particularly a kind of two sections endless apron formula freezing plants.
Background technology:
In existing two sections endless apron formula freezing plants, the top blast wind evaporimeter and the horizontal centrifugal blower that are used for cycle heat exchange have taken freezing plant inside than large space, make in the nonproductive process the inner narrow space of carrying out artificial cleaning of device.
In existing two sections endless apron formula freezing plants, frozen article and wrap up in the moisture content of band and get on holder rail below the conveyer belt, to freeze and progressively to thicken to form behind the freezing plant and carry ice on the back, the serious ice phenomenon of carrying on the back causes the conveyer belt breakage.
In existing two sections endless apron formula freezing plants, be positioned at the low temperature conveyer belt that feeding mechanism bottom is come out by the body of thermal insulating box transmission and be in operation and only have sparge pipe that its bath is heated up and clean, it is big to consume the water yield, and the intensification cleaning performance is poor.
In the existing two-part endless apron formula freezing plant, the tensioning of second section endless apron is to realize inconvenient operation through the position of adjustment driving beaming roller.
Summary of the invention:
The purpose of the utility model is in order to overcome above deficiency, a kind of technical scheme of freezing plant to be provided, and the horizontal centrifugal blower of this device is installed in the below of top blast wind evaporimeter as much as possible; Make the inner space of artificial cleaning that supplies of device spacious; This device has anti-freeze carriage and Steam Heating abat-vent below the conveyer belt that entering is freezed, eliminate under the conveyer belt and carry the ice phenomenon on the back, in this device feeding mechanism bottom water tank is arranged; The low temperature conveyer belt cleans after water tank heats up again; Using water wisely, the tensioning beaming roller of second section endless apron of this device is positioned at body of thermal insulating box near the discharging mechanism place, and is easy to operate.
The object of the invention is realized through following technical scheme: a kind of freezing plant comprises body of thermal insulating box; Place the feeding mechanism and the discharging mechanism of body of thermal insulating box charging aperture and discharging opening respectively; Be contained in feeding web frame and discharging conveyer belt frame in the body of thermal insulating box; First section endless apron is installed on the feeding web frame, second section endless apron is installed on the discharging conveyer belt frame, be positioned at the top blast wind evaporimeter of body of thermal insulating box and the air-cooler that horizontal centrifugal blower constitutes; The feed pipe of top blast wind evaporimeter links to each other with refrigeration unit respectively with muffler; The driving beaming roller of first section endless apron is connected with electric reducer respectively and transmission with the driving beaming roller of second section endless apron, the evaporator support that below top blast wind evaporimeter, has crossbeam and support bar to connect into, and the crossbeam below is provided with at least two support bars; The upper end and the crossbeam of support bar is connected, the lower end of support bar and body of thermal insulating box are connected the composition primary structure member; Horizontal centrifugal blower is packed on the shaped as frame blower fan frame, and shaped as frame blower fan frame is connected with the support bar of two parallel primary structure members respectively and forms a stress frame, and the evaporimeter below has a stress frame at least.Convey materials gets into first section endless apron below of freezing in the said body of thermal insulating box has anti-freeze carriage; There is installing plate at the two ends of said anti-freeze carriage; Installing plate and feeding web frame are connected, and all adopt polytetrafluoroethylmaterial material on the last plane of said anti-freeze carriage and two sides, form the polytetrafluoroethylene (PTFE) bearing-surface; Between the last plane of polytetrafluoroethylene (PTFE) bearing-surface and two sides wear rib is arranged, the conveyer belt below has an anti-freeze carriage at least.
Further improvement of the present invention is: there is the Steam Heating abat-vent first section endless apron below at said body of thermal insulating box charging aperture place; The deep bead and the body of thermal insulating box of said Steam Heating abat-vent are connected, and the lower edge, side of the last plane of said Steam Heating abat-vent and the polytetrafluoroethylene (PTFE) bearing-surface of anti-freeze carriage joins and the body of thermal insulating box outside is downward-sloping relatively.
Further improvement of the present invention is: water tank is arranged at said feeding mechanism bottom, and there are guiding beaming roller and tensioning beaming roller in said water tank top, and the first section endless apron that is tensioned sinks to below the liquid level of water tank.
Further improvement of the present invention is: in the said body of thermal insulating box near in two guiding beaming rollers at discharging mechanism place the next one be the tensioning beaming roller; The tensioning shaft of tensioning beaming roller is installed on the installed part that is connected in discharging conveyer belt frame both sides with adjusting screw(rod); Guide wheel is installed on the tensioning shaft; Locate with check ring each guide wheel both sides, regulates the position of guiding beaming roller through adjusting screw(rod) and come second section endless apron of tensioning.
Advantage of the present invention is:
The evaporator support of top blast wind evaporimeter below has shaped as frame blower fan frame to be connected; Stability Analysis of Structures; Improve the security of evaporimeter installation process, horizontal centrifugal blower is installed in top blast wind evaporimeter below, so no longer takies other and supplies the artificial inner space of cleaning; Can make things convenient for inner the cleaning, reduce health concerns.
The anti-freeze carriage in conveyer belt below is attend institute's layers of ice and is separated with ptfe surface; Having eliminated under the conveyer belt freezes carries the ice phenomenon on the back, and the Steam Heating abat-vent of body of thermal insulating box charging tapping conveyer belt below had both stoped in the body of thermal insulating box leaking of high pressure cold wind under the conveyer belt, again this position moisture of accepting conveyer belt that is in operation is discharged; Do not cause this position to carry ice on the back; Owing to there is not the mechanical breakdown of carrying ice phenomenon and initiation thereof on the back, can prolong the continuous operation time of freezing plant, improve and freeze efficient.
Water tank is arranged at feeding mechanism bottom, and there are guiding beaming roller and tensioning beaming roller in the water tank top, again by the sparge pipe flushing, cleans the water yield and consumes and lack after the low temperature conveyer belt that is come out by transmission in the body of thermal insulating box is immersed in and heats up in the water tank, and cleaning performance is good.
Guiding beaming roller and the tensioning beaming roller conveyer belt that transmission is come out to the driving beaming roller near the discharging mechanism place in the body of thermal insulating box carry out tensioning, and needed tensile force is little, and is easy to operate.
