Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and in particular to a flushing hub device for a spiral quick-freezing machine. Background Technology

[0002] A spiral quick-freezing machine is a quick-freezing equipment. Its conveyor belt is driven by a rotating hub. Under the guidance of the guide rail, the conveyor belt realizes a spiral upward conveying action. In order to improve production capacity and work efficiency, the conveyor belt usually needs to be spiraled in multiple layers to achieve a larger belt area within a certain floor space. However, as the number of belt layers increases, the related frame structure also becomes more complex.

[0003] Since spiral quick-freezing machines are also used to produce various quick-frozen foods, they have high requirements for food hygiene. Therefore, the conveyor belt and related structures need to be cleaned regularly. The traditional cleaning method mainly relies on manual labor, that is, the operator holds a water hose to rinse the frame. This method is time-consuming and laborious, not only with low work efficiency, but also sometimes requires the operator to climb to a height, which poses certain safety hazards. Most importantly, due to the relatively complex structure related to the frame, the above cleaning method will inevitably have a large number of blind spots in the rinsing, which will affect food safety.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] This invention addresses the aforementioned shortcomings of existing technologies by proposing a rinsing hub device that is simple in structure, ingeniously designed, and rationally laid out, enabling rapid, efficient, and convenient cleaning of the mesh belt frame portion of a spiral quick-freezing machine.

[0006] The technical solution of this utility model is: a flushing hub device for a spiral quick-freezing machine, characterized in that: the device includes a flushing pipe 1, which is arranged on the outside of the quick-freezing machine hub; the quick-freezing machine hub includes a rotating cage 2, and an upper rotating shaft 3 and a lower rotating shaft 4 are arranged at both ends of the rotating cage 2.

[0007] The flushing pipe 1 is distributed along the generatrix of the rotating cage 2. Multiple nozzles 5 are evenly spaced on the flushing pipe 1. A drain pipe 6 is connected to the bottom of the flushing pipe 1, and a valve is installed on the drain pipe 6. The top of the flushing pipe 1 is connected to a radial pipe 7, and the other end of the radial pipe 7 is connected to the inner cavity of the upper rotating shaft 3.

[0008] The upper rotating shaft 3 is connected to the water inlet pipe 9 via a rotary joint 8, and an anti-loosening connector 10 is also provided between the rotary joint 8 and the water inlet pipe 9.

[0009] The anti-loosening connector 10 includes two matching semi-annular connectors 11. These two semi-annular connectors 11 are connected to each other by bolts and are tightly held on the outside of the water inlet pipe 9. One of the semi-annular connectors 11 is provided with an anti-loosening hook 12, the end of which is engaged in the groove 13 opened at the end of the transmission shaft 3.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This type of spiral quick-freezing machine flushing hub device features a simple structure, ingenious design, and reasonable layout. Addressing the problems associated with traditional manual cleaning of the conveyor belt structure in quick-freezing machines, it employs a unique design. A flushing pipeline is directly installed on the outside of the quick-freezing machine hub. As the hub rotates, multiple nozzles on the flushing pipeline evenly spray clean water onto the conveyor belt frame structure, achieving automatic and thorough flushing. This device can replace manual flushing, effectively improving flushing efficiency and saving labor costs. Furthermore, its manufacturing process is simple and inexpensive. Therefore, it possesses numerous advantages and is particularly suitable for widespread application in this field, with a very broad market prospect. Attached Figure Description

[0015] Figure 4 yes Figure 3 Enlarged view of part A in the image. Detailed Implementation

[0016] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 4 The image shows a flushing hub device for a spiral quick-freezing machine. The device includes a flushing pipe 1 located on the outside of the quick-freezing machine hub. The quick-freezing machine hub includes a rotating cage 2, with an upper rotating shaft 3 and a lower rotating shaft 4 located at both ends of the rotating cage 2.

[0017] The flushing pipe 1 is distributed along the generatrix of the rotating cage 2. Multiple nozzles 5 are evenly spaced on the flushing pipe 1. A drain pipe 6 is connected to the bottom of the flushing pipe 1, and a valve is installed on the drain pipe 6. The top of the flushing pipe 1 is connected to a radial pipe 7, and the other end of the radial pipe 7 is connected to the inner cavity of the upper rotating shaft 3.

[0018] The upper rotating shaft 3 is connected to the water inlet pipe 9 via a rotary joint 8, and an anti-loosening connector 10 is also provided between the rotary joint 8 and the water inlet pipe 9.

[0019] The anti-loosening connector 10 includes two matching semi-annular connectors 11. These two semi-annular connectors 11 are connected to each other by bolts and are tightly held on the outside of the water inlet pipe 9. One of the semi-annular connectors 11 is provided with an anti-loosening hook 12, the end of which is engaged in the groove 13 opened at the end of the transmission shaft 3.

[0020] The working process of the rinsing hub device for the spiral quick-freezing machine in this embodiment of the utility model is as follows: First, the outlet pipe of the water pump is connected to the inlet pipe 9. When the spiral quick-freezing machine is working normally, the drive mechanism inside it will drive the hub to rotate at a constant speed. When it is necessary to rinse the mesh belt and related structures of the spiral quick-freezing machine, the water pump is started, and clean water is pumped into the inner cavity of the upper rotating shaft 3 through the inlet pipe 9. The clean water enters the rinsing pipe 1 through the upper rotating shaft 3 and the radial pipe 7, and is sprayed out through multiple nozzles 5. At this time, the valve on the drain pipe 6 is in the closed state. Since the inlet pipe 9 and the rotating shaft 3 are connected by a rotary joint 8, the clean water can be transported while the hub is rotating at a constant speed, so that the clean water sprayed from the nozzles 5 can evenly rinse the mesh belt and related structures, achieving an automated rinsing operation without dead angles.

[0021] After the rinsing operation is completed, when the drum stops rotating, open the valve on the drain pipe 6 to drain the water remaining in the rinsing pipe 1 to prevent the residual water from freezing and causing damage to the rinsing pipe 1.

[0022] When the hub rotates, the anti-loosening connector 10 can prevent relative movement between the rotary joint 8 and the water inlet pipe 9 along the axial direction, thereby preventing them from separating.

[0023] Since the two semi-annular connectors 11 in the anti-loosening connector 10 are tightly held on the water inlet pipe 9, and the end of the anti-loosening hook 12 connected to one of the semi-annular connectors 11 is stuck in the groove 13 opened on the transmission shaft 3, once axial movement occurs between the water inlet pipe 9 and the rotary joint 8, the anti-loosening hook 12 will be stuck on the side wall of the groove 13, limiting their axial direction and thus preventing them from separating from each other.
