Problems solved by technology

[0006] The purpose of the present invention is to overcome the above deficiencies and provide a technical solution for a freezing device. The horizontal centrifugal fan of the device is installed under the top blowing evaporator as much as possible, so that the space for manual cleaning inside the device is spacious. The device has an anti-icing bracket and a steam heating windshield device under the frozen conveyor belt to eliminate the phenomenon of ice under the conveyor belt. There is a water tank at the bottom of the feeding mechanism of the device. The low-temperature conveyor belt is cleaned after the water tank is heated up, saving energy With water, the tension shaft roller of the second section of the circulating conveyor belt of the device is located in the heat insulation box near the discharge mechanism, which is easy to operate

Embodiment 1

[0035] freezer (see figure 1 , figure 2 ) includes a heat insulating box body 1, a feeding mechanism 4 and a material discharging mechanism 5 respectively placed in the material inlet 2 and the material outlet 3 of the heat insulating box body 1, and the feeding conveyor belt frame 6 installed in the heat insulating box body 1 And the discharge conveyor belt frame 7, the first section of the loop conveyor belt 8 and the second section of the loop conveyor belt 9 installed on the feed conveyor belt frame 6 and the discharge conveyor belt frame 7 respectively, are located at the feed mechanism 4 The flushing device 10 below, the blowing device 11 , the water collecting tray 12 , the air cooler that is positioned at the air blowing evaporator 13 and the horizontal centrifugal fan 14 in the heat insulation box 1 constitutes. The liquid supply pipe 15 and the air return pipe 16 of the top blowing evaporator 13 are respectively connected with the refrigerating unit, and the drivin...

Embodiment 2

[0037] The difference with Embodiment 1 is: there is an anti-icing bracket 23 below the first section of circulating conveyor belt 8 that enters freezing in the heat-insulating box 1 (see Figure 5 , Figure 6 , Figure 7 ), the two ends of the anti-icing bracket 23 have mounting plate 24 and feed conveyor belt frame 6 to be fixedly connected. The upper plane 25 and the two side faces 26 of the anti-icing bracket 23 basically all adopt polytetrafluoroethylene material to form a polytetrafluoroethylene support surface, and there is a gap between the upper plane 25 and the two side faces 26 of the polytetrafluoroethylene material Wear-resistant strip 27 of ultra-high molecular polyethylene material. 28 is a mounting screw, 29 is a mounting screw, 30 is a mounting nut, and the polytetrafluoroethylene sleeve 31 is connected to the mounting screw 29 with a cotter pin 32 . There is at least one anti-icing bracket 23 below the first section of endless conveyor belt 8 , and multiple...

Embodiment 3

[0039] The difference with Embodiment 1 or 2 is that there is a steam heating windshield device 33 below the first section of the circulating conveyor belt 8 at the inlet 2 of the heat-insulating box body 1 (see Figure 8 , Figure 9 , Figure 10 ), the windshield 34 of the steam heating windshield 33 is fixedly connected with the heat insulation box body 1, and the upper plane 35 of the steam heating windshield 33 and the side 26 lower edge of the polytetrafluoroethylene of the anti-icing bracket 23 are connected And the outside of the heat insulation box 1 is inclined downward. The windshield 34 and the upper plane 35 are fixed on the heating pipe 37 with the heat conduction plate 36, and the steam pipe 38 is inserted in the heating pipe 37, and there is a return steam pipe 39 at the bottom of the heating pipe 37, and the steam enters the steam pipe 38 and enters the heating pipe 37, Flow out through return pipe 39 again.

Abstract

The invention discloses a freezing device comprising a heat insulating tank body, a feeding mechanism, a discharging mechanism, two conveying belts, a conveying belt stand, a top-blowing evaporator and a horizontal type centrifugal fan, wherein the feeding mechanism and a discharging mechanism are respectively arranged on a feed port and a discharge port of the heat insulating tank body, and the two conveying belts, the conveying belt stand, the top-blowing evaporator and the horizontal type centrifugal fan are arranged in the heat insulating tank body; a supporting rod is arranged below a cross beam of a support of the top-blowing evaporator, the supporting rod, the cross beam and the heat insulating tank body are fixedly connected to form a stressed member, and a frame-shaped fan stand is fixedly arranged on the supporting rod of the stressed member to form a stressed frame; an anti-icing bracket is arranged below the frozen conveying belt, a steam heating wind-shielding device is arranged below the conveying belt at the feeding port, the bottom of the feeding mechanism is provided with a conveying belt heating-up water tank, and a conveying belt tensioning shaft roll is arranged at the discharging mechanism. The invention has the advantages of stable structure, safe installation process of the evaporator and convenient use and also has the advantages of eliminating the phenomenon of icing under the conveying belts, prolonging the continuous running time of the freezing device and improving efficiency; and besides, because the low-temperature conveying belt is washed after immersed in the water tank and heated up, less water consumption and good cleaning effect are achieved.

Description

Technical field: [0001] The invention relates to a freezing device, in particular to a two-stage circulating conveyor belt type freezing device. Background technique: [0002] In the existing two-stage circulating conveyor belt freezing device, the top blowing evaporator and the horizontal centrifugal fan used for circulating heat exchange occupy a large space inside the freezing device, leaving no room for manual cleaning inside the device during the non-production process. narrow. [0003] In the existing two-stage circulating conveyor belt freezing device, the water wrapped by the frozen product enters the freezing device and freezes on the support rail under the conveyor belt and gradually thickens to form pack ice. The severe pack ice phenomenon causes the conveyor belt to damaged. [0004] In the existing two-stage circulating conveyor belt type freezing device, the low-temperature conveyor belt located at the bottom of the feeding mechanism and driven out of the hea...
