Background technique

In order to prevent aquatic products from rotting and deteriorating during transportation and storage, it is necessary to freeze aquatic products for transportation and storage. The freezing of aquatic products is done through quick freezers. In Chinese patent No. 932240216, the date of authorization announcement is May 25, 1995, and a kind of freezing machine is disclosed in the patent document called "Tunnel Type Single Freezer". The quick-freezing chamber formed by the quick-freezing mechanism located in the heat preservation chamber, and the conveyor belt located in the quick-freezing chamber. When in use, the quick-freezing box containing the object to be frozen and water is placed on the conveyor belt, and the conveyor belt makes the quick-freezing box pass through the quick-freezing chamber. When the quick-freezing box passes through the quick-freezing chamber, the water is frozen into ice and wrapped on the object to be frozen to form a frozen product. . The existing tunnel-type quick-freezing machines generally have the following disadvantages: the conveyor belt does not have the function of shock isolation, and the vibration generated during the conveying process will cause the water in the quick-freezing box to shake out; when the aquatic products are fully wrapped quick-freezing, the ice cubes It is in a solid state, so the weight of the frozen product after freezing is heavy, and the transportation cost is high if the weight of the frozen product is heavy.

Contents of the invention

The first purpose of the present invention is to provide an aquatic product freezer with little vibration produced by the quick-freezing box during the process of transporting the quick-freezing box, which solves the problem that the vibration generated in the delivery process of the existing quick-freezing machine will make the water in the quick-freezing box Shaking out the question.

The second purpose of the present invention is to further provide an aquatic product freezer capable of making the ice cubes wrapped in the object a hole structure, which solves the problem that the ice cubes wrapped in the objects formed by the existing quick-freezing machine are of a solid structure The resulting frozen products are heavy in weight.

The above technical problems are solved by the following technical solutions: an aquatic product freezer, including a quick-freezing chamber and a conveyor belt passing through the quick-freezing chamber, and the conveyor belt is provided with a number of quick-freezing box support frames distributed along the extending direction of the conveyor belt. The supporting frame of the quick-freezing box includes an upper base plate, a middle base plate and a lower base plate distributed in sequence, a number of upwardly inclined support plates are arranged between the upper base plate and the middle base plate, and the upper base plate, the middle base plate and the upward inclined support plate are surrounded by a wall along the horizontal direction. Extended upper deformation channel, a number of inclined support plates are arranged between the lower base plate and the middle base plate, and a lower deformation channel is formed between the lower base plate, the middle base plate and the lower inclined support plate, and the lower base plate and the conveyor belt are connected in Together. During use, the quick-freezing box is placed on the upper base and transported to the quick-freezing chamber by the conveyor belt for quick-freezing. When the conveyor belt vibrates, the support frame of the quick-freezing box can play a role of vibration isolation, so that the vibration generated by the conveyor belt is not easily transmitted to the quick-freezing box. out. The above structural form of the quick-freezing box support frame can use a plate structure to ensure structural strength, overall bending and torsional strength, and reduce weight at the same time. Therefore, the quick-freezing box support frame of this structure not only has the advantages of compact plate structure, small space occupation and simple appearance, but also has the advantages of good vibration isolation effect of truss structure.

When the support frame of the quick-freezing box is subjected to high-frequency and low-amplitude vibrations, the deformation channel will not deform or have minimal deformation. At this time, the damping fluid will not flow in the damping channel, so the high-frequency and low-amplitude vibrations are not easily eliminated. At this time, the energy-absorbing rod will shake and generate friction with the liquid, thereby effectively eliminating the high-frequency and low-amplitude vibration energy. The energy absorption and vibration isolation effect of the support frame of the quick-freezing box can be further improved.

The ice hole is a closed structure, which can reduce the contact area between the ice in the frozen product and the air. If the contact area is small, the ice in the frozen product is not easy to melt.

In this embodiment, since the section of the sealing reinforcement ring and the expansion groove is trapezoidal, when the seal is poor due to fatigue surface aging and other reasons, the resealing can be realized by further increasing the depth of the seal reinforcement ring inserted into the expansion groove. This sealing method has low requirements on manufacturing precision and is easy and labor-saving during assembly. This sealing method can improve the sealing effect instead of deteriorating like the existing sealing method no matter what kind of relative movement occurs between the water inlet port 1 and the water inlet pipe 5 . If water seeps from between the sealing tube 9 and the accommodation tank 11, the penetration force of this part of the water will make the spigot and all the sealing lips abut more tightly, that is, the better the seal. When the space penetrates, the water must first pass through the outwardly inclined sealing lip, and the penetrating force of this part of the water will make the outwardly inclined sealing lip and the tongue abut more tightly, that is, the better the seal, so that the water cannot flow out, so this sealing method will The seal is better as the water pressure increases.
