Description

TECHNICAL FIELD

[0001] The utility model relates to the production technical field of puffing device, specifically relates to a gas pump puffing device. BACKGROUND

[0002] In the working process of the ice cream machine and other puffing devices, the peristaltic pump pumps the slurry in the material bucket to the evaporator freezing cylinder, and in the process of feeding, air is sucked into the pipeline through the air inlet for mixing. Figure 1 As shown in the drawings, when the peristaltic pump stops working, the peristaltic pump presses the hose at point A to avoid liquid leakage; because the air inlet is connected with the outside world, the liquid in the BC segment of the liquid inlet pipe will fall into the material bucket due to gravity after the peristaltic pump stops working, so that a cavity is formed in the BC segment. When the peristaltic pump works again, the air in the BC segment needs to be pumped away before the slurry can be pumped up, and after the peristaltic pump is started and stopped for many times, the air in the BC segment will accumulate in the evaporator freezing cylinder, resulting in too much gas in the evaporator freezing cylinder, and the gas will be suddenly sprayed out during the ice cream discharging process, so that the ice cream discharging is discontinuous, and a "puff" sound is generated. SUMMARY

[0003] The utility model discloses to aim at the prior art existing problem, provide a kind of gas pump puffing device.

[0004] To achieve the above object, the technical scheme adopted by the utility model is:

[0005] A kind of gas pump puffing device, including material bucket, peristaltic pump and evaporator freezing cylinder, the peristaltic pump is connected with the evaporator freezing cylinder by pipeline;Material bucket and the peristaltic pump between the feeding assembly are equipped, and the feeding assembly includes the feeding pipe segment connected with the peristaltic pump, and the liquid inlet pipe and the air inlet pipe communicated with the feeding pipe segment, the liquid inlet pipe is connected to the material bucket, one end of the air inlet pipe is equipped with air inlet pump and is equipped with stop valve near end portion, vacuum pump is further equipped on the air inlet pipe or the feeding pipe segment.

[0006] The gas pump puffing device can reduce the gas entering the liquid inlet pipe and the feeding pipe segment when the peristaltic pump is closed by improving the feeding assembly, avoid pumping too much gas into the evaporator freezing cylinder when the peristaltic pump is started again, reduce the accumulation of air in the evaporator freezing cylinder, so as to avoid affecting the continuous ice cream discharging and emitting the sound of air explosion.

[0007] The setting of the stop valve can completely close the air inlet pipe, avoid new gas entering the feeding assembly;The setting of the vacuum pump can further form micro negative pressure, and the residual gas in the air inlet pipe, the liquid inlet pipe or the feeding pipe segment is pumped out, which greatly avoids that the pure gas without mixing with liquid in the pipeline enters the evaporator freezing cylinder and is sprayed from the discharging nozzle.

[0008] When the vacuum pump and the stop valve are matched and arranged, the liquid in the liquid inlet pipe will fall back after the vacuum pump is started, and a small amount of liquid can be sucked or sucked back, so that the liquid occupies the space in the pipe, thereby reducing the residual space of the gas in the pipe or the emergence of the vacuum space.

[0009] When the peristaltic pump stops working, the stop valve is closed to separate the external air from the liquid inlet pipe, so that the air continuously enters the liquid inlet pipe. Although the liquid in the liquid inlet pipe will fall into the barrel again under the action of gravity, the amount of falling liquid is limited because no new air enters. After the peristaltic pump is started again, the air brought into the evaporator refrigeration cylinder is small, and the gas will not suddenly spray out during the ice cream discharging process, so that the ice cream discharging is continuous, and the possibility of causing the "puff" gas explosion sound of the ice cream is reduced.

[0010] Further, the air inlet pipe located downstream of the stop valve is also provided with a filter. The filter can be an air filter that can filter impurities and harmful substances in the air pumped into the air inlet pipe, thereby meeting the user's demand for health and safety under the premise of ensuring the ice cream expansion rate.

[0011] In some embodiments, the liquid inlet pipe, the air inlet pipe and the feed pipe section are connected by a tee joint.

[0012] Further, the liquid inlet pipe and the air inlet pipe are coaxially arranged.

[0013] In some embodiments, the feed pipe section is connected and communicated with the liquid inlet pipe, the other end of the liquid inlet pipe is inserted into the barrel and connected with a branch pipe near the end inlet, the other end of the branch pipe extends from the barrel and is connected with the air inlet pipe.

[0014] A branch pipe is additionally arranged beside the liquid inlet pipe, and the air inlet pipe is arranged above the branch pipe, so that pure gas can be effectively prevented from entering the liquid inlet pipe when the peristaltic pump stops working. When the peristaltic pump is started again, the air in the branch pipe is mixed with the liquid material in the liquid inlet pipe and is pumped into the evaporator refrigeration cylinder, which can not only reduce the mixing of too much air at the beginning, but also avoid the gas explosion sound caused by opening the ice cream discharge nozzle.

[0015] Further, the lower end of the branch pipe is in an arc shape, and the diameter of the branch pipe is not greater than the diameter of the liquid inlet pipe.

[0016] Further, the branch pipe is connected to the liquid inlet pipe at a distance of 1-10 mm from the end inlet of the liquid inlet pipe.

[0017] Further, the branch pipe is connected with the lower end of the liquid inlet pipe to form a U-shaped structure, and the end of the liquid inlet pipe extends to the lower side of the U-shaped structure to form an end inlet, that is, the two form a shape similar to a lower-case "u" after being connected, and an end inlet exists on the lower side of the right side, which can be used to introduce liquid materials.

[0018] The gas pump puffing device comprises a material bucket, a peristaltic pump and an evaporator refrigeration cylinder, the peristaltic pump is connected with the evaporator refrigeration cylinder through a pipeline, a feeding assembly is arranged between the material bucket and the peristaltic pump, the feeding assembly comprises a feeding pipe section connected with the peristaltic pump, the feeding pipe section is connected and communicated with a liquid inlet pipe, the other end of the liquid inlet pipe is inserted into the material bucket and connected with a branch pipe near an end inlet, the other end of the branch pipe extends out of the material bucket and is connected with an air inlet pipe, and the other end of the air inlet pipe is provided with an air inlet pump and a stop valve near the end.

[0019] Compared with the prior art, the gas pump puffing device has the following beneficial effects: 1. The feeding assembly is improved, so that the gas in the liquid inlet pipe and the feeding pipe section can be reduced when the peristaltic pump is closed, the excessive gas can be prevented from being pumped into the evaporator refrigeration cylinder when the peristaltic pump is started again, the accumulation of air in the evaporator refrigeration cylinder is reduced, and the continuous discharge of ice cream and the gas explosion sound are avoided; 2. The stop valve can completely close the air inlet pipe, so that new gas cannot enter the feeding assembly, the air brought into the evaporator refrigeration cylinder is less when the peristaltic pump is started again, the gas cannot be suddenly sprayed out during the ice cream discharge process, the ice cream is continuously discharged, the possibility of causing the gas explosion sound of the ice cream is reduced, and the vacuum pump can further form a micro-negative pressure to exhaust the residual gas in the air inlet pipe, the liquid inlet pipe or the feeding pipe section, so that the simple gas in the pipe which is not mixed with liquid materials can be prevented from entering the evaporator refrigeration cylinder and being sprayed out of the discharge nozzle; 3. The branch pipe is additionally arranged beside the liquid inlet pipe, and the air inlet pipe is arranged above the branch pipe, so that the simple gas in the liquid inlet pipe after the peristaltic pump stops working can be further effectively avoided, the excessive air mixed at the beginning can be reduced, and the gas explosion sound caused by opening the ice cream discharge nozzle can be avoided.

[0026] The technical scheme of the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] In the description of the utility model, it is necessary to explain that the orientation or position relationship indicated by the terms "intermediate", "upper", "lower", "left", "right", "inner", "outer" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as the limitation of the utility model. Embodiment 1

[0028] As shown in Figure 2 An air pump bulking device, including material bucket 1, peristaltic pump 2 and evaporator refrigeration cylinder 3, the peristaltic pump 2 with the evaporator refrigeration cylinder 3 is connected through the pipeline;The material bucket 1 with the peristaltic pump 2 is equipped with feed assembly, the feed assembly includes the feed pipe section 4 connected with the peristaltic pump 2, and the liquid inlet pipe 5 and the air inlet pipe 6 in communication with the feed pipe section 4, the liquid inlet pipe 5 is connected to the material bucket 1, one end of the air inlet pipe 6 is equipped with air pump 7 and is equipped with stop valve 8 close to the end.

[0029] After the peristaltic pump 2 stops working, tighten the shut-off valve 8 to separate the external air from the liquid inlet pipe 5, preventing air from continuously entering the liquid inlet pipe 5. When the peristaltic pump 2 stops working, because the liquid in the liquid inlet pipe 5 does not have time to fall into the material tank during the short time that the peristaltic pump 2 stops rotating, after the shut-off valve 8 is closed in time, although some of the liquid in the liquid inlet pipe 5 will fall into the material tank again under its own weight, the amount of liquid falling is limited because no new air enters. After the peristaltic pump 2 is restarted, less air is brought into the evaporator cooling cylinder 3, and gas will not suddenly spray out during the ice cream dispensing process, making the ice cream dispensing continuous and reducing the possibility of causing the ice cream to "pop" and explode. Example 2

[0030] like Figure 3 As shown, a pneumatic pump expansion device includes a material tank 1, a peristaltic pump 2, and an evaporator cooling cylinder 3. The peristaltic pump 2 and the evaporator cooling cylinder 3 are connected by a pipe. A feeding assembly is provided between the material tank 1 and the peristaltic pump 2. The feeding assembly includes a feeding pipe section 4 connected to the peristaltic pump 2, and a liquid inlet pipe 5 and an air inlet pipe 6 communicating with the feeding pipe section 4. The liquid inlet pipe 5 is connected to the material tank 1. An air inlet pump is provided at one end of the air inlet pipe 6 and a shut-off valve 8 is provided near the end. A vacuum pump 9 is also connected to the air inlet pipe 6 downstream of the shut-off valve 8.

[0031] Furthermore, the liquid inlet pipe 5, the air inlet pipe 6, and the feed pipe section 4 are connected by a tee. The liquid inlet pipe 5 and the air inlet pipe 6 are arranged coaxially.

[0032] After the peristaltic pump 2 stops working, tighten the shut-off valve 8 to separate the air from the inlet pipe and prevent air from entering the feed pipe. When the peristaltic pump stops working, the liquid in the inlet pipe 5 does not have time to fall into the feed tank 1 after the peristaltic pump stops rotating. After the shut-off valve 8 is closed in time, although the liquid in the inlet pipe 5 falls into the feed tank due to gravity, in order to expel as much air as possible from the inlet pipe, after the liquid in the inlet pipe 5 falls into the feed tank 1, start the vacuum pump 9. After the pressure reading on the vacuum gauge approaches a negative pressure of 0.1 MPa, turn off the vacuum pump 9. There is no air in the inlet pipe 5, and very little air is carried into the evaporator cooling cylinder 3. After multiple start-stop cycles, very little gas accumulates in the evaporator cooling cylinder 3, greatly reducing the possibility of ice cream blistering. Example 3

[0033] like Figure 4As shown, a kind of air pump puffing device, including barrel 1, peristaltic pump 2 and evaporator refrigeration cylinder 3, the peristaltic pump 2 with the evaporator refrigeration cylinder 3 between by pipeline connection;Between the barrel 1 with the peristaltic pump 2 is equipped with feed assembly, the feed assembly includes with the peristaltic pump 2 connection feed pipe section 4, the feed pipe section 4 is connected and communicates with liquid inlet pipe 5, the other end of the liquid inlet pipe 5 is inserted into the barrel 1 and is connected with branch pipe 11 in the place near the end import, the other end of the branch pipe 11 is stretched out from the barrel 1 and is connected with air inlet pipe 6, the other end of the air inlet pipe 6 is equipped with air inlet pump and is equipped with stop valve 8 near the end.

[0034] Further, the air inlet pipe 6 downstream of the stop valve 8 is also equipped with filter 10.The branch pipe 11 with the lower end of the liquid inlet pipe 5 is connected to form U-shaped structure, and the end of the liquid inlet pipe 5 extends to the lower part of the U-shaped structure to form an end import, that is, after being connected, it forms a shape similar to the lower-case "u", and there is an end import on the right lower part, which can import liquid.

[0035] When the peristaltic pump 2 stops working, tighten the stop valve 8, separate the air from the air inlet pipe 6, avoid air entering the U-shaped section of the branch pipe 11 and the liquid inlet pipe 5, because the peristaltic pump stops working, although the liquid in the liquid inlet pipe falls into the barrel due to gravity when the peristaltic pump stops rotating, basically no air enters the liquid inlet pipe 5 on the right side of the U-shaped section because it is separated by the U-shaped section with liquid, the air brought into the evaporator refrigeration cylinder 3 is less, and the possibility of ice cream explosion is reduced. At the same time, because the upper stop valve of the air inlet pipe above the branch pipe is closed, no air enters the U-shaped section of the branch pipe, when the peristaltic pump works next time, open the stop valve, the feed pipe section 4 on the left side of the peristaltic pump 4 has no air, and the air in the U-shaped section has been communicated with the atmosphere through the stop valve, the pressure difference generated by the U-shaped section pushes the ice cream into the liquid inlet pipe 5, and gradually pushes it into the evaporator refrigeration cylinder 3 through the peristaltic pump 2, because the feed pipe section 4 on the left side of the peristaltic pump basically has no air, the probability of ice cream explosion is further reduced. At the same time, because the filter 10 filters the air, it meets the user's demand for hygiene under the premise of ensuring the puffing rate of ice cream. Example 4

[0036] As Figure 5As shown, a kind of air pump puffing device, including barrel 1, peristaltic pump 2 and evaporator refrigeration cylinder 3, the peristaltic pump 2 with the evaporator refrigeration cylinder 3 between by pipeline connection;The barrel 1 with the peristaltic pump 2 between being equipped with feed assembly, the feed assembly includes with the peristaltic pump 2 connection feed pipe section 4, and with the feed pipe section 4 intercommunication liquid inlet pipe 5 and air inlet pipe 6, the liquid inlet pipe 5 is connected to the barrel 1, the air inlet pipe 6 one end is equipped with air inlet pump and is close to end portion and is equipped with stop valve 8, the feed pipe section 4 is also equipped with vacuum pump 9 on.

[0037] The feed pipe section 4 is connected and communicates the liquid inlet pipe 5, the other end of the liquid inlet pipe 5 is inserted into the barrel 1 and is connected branch pipe 11 in the place of being close to end portion import, the other end of the branch pipe 11 is stretched out from the barrel 1 and is connected the air inlet pipe 6.The branch pipe 11 is connected with the lower end of the liquid inlet pipe 5 and forms the structure of U-shaped section, the end of the liquid inlet pipe 5 extends to the lower of U-shaped section and forms end portion import, that is, after being connected, it forms the shape similar to lower-case "u", there is an end portion import in the lower right, can import liquid material.

[0038] Further, the air inlet pipe 6 is also equipped with filter 10 downstream of the stop valve 8.

[0039] Further, the lower end of the branch pipe 11 is arc structure, and the diameter of the branch pipe 11 is less than the diameter of the liquid inlet pipe 5.

[0040] After the peristaltic pump 2 stops working, the stop valve 8 is tightened, air is separated from the air inlet pipe 6, and new air is prevented from entering the branch pipe 11. Since the liquid in the liquid inlet pipe 5 has not had time to fall into the barrel after the peristaltic pump stops rotating, the stop valve 8 is closed in time, the liquid in the liquid inlet pipe 5 will fall into the barrel 1 due to gravity, but in order to maximize the air in the left feed pipe section 4 of the peristaltic pump, the vacuum pump 9 is started after the liquid falls into the barrel in the U-shaped section, and the vacuum pump 9 is closed when the pressure value on the vacuum gauge approaches -0.1 MPa. There is no air in the left feed pipe section 4 of the peristaltic pump, and the air brought into the evaporator refrigeration cylinder 3 is minimal. At the same time, since the upper stop valve of the air inlet pipe 6 is closed, no air enters the U-shaped section. When the peristaltic pump 2 works next time, the stop valve 8 is opened. The left feed pipe section 4 of the peristaltic pump has no air due to vacuum, and the air on the left side of the U-shaped section has been communicated with the atmosphere through the stop valve. The pressure difference formed pushes the ice cream into the liquid inlet pipe 5 of the U-shaped section. Since the feed pipe section 4 has no air, the possibility of ice cream explosion is greatly reduced. At the same time, the filter 10 filters the air, which can meet the user's demand for health and safety on the premise of ensuring the puffing rate of ice cream.

[0041] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
