Description

Technical Field

[0001] The utility model relates to the field of rubber extruders, in particular to a rubber extruder. Background Art

[0002] Rubber extruder is a device used to extrude semi-finished and finished products of paste rubber. It is indispensable in the production process. At present, due to the limitations of process and production equipment in the production process of paste rubber, the produced materials are often mixed with a large amount of waste gas. The mixture of waste gas and materials will not only produce odor but also affect the quality of the finished product.

[0003] In the prior art, an exhaust pipe is often formed upward on the side of the barrel of the rubber extruder, and a valve is provided on the exhaust pipe. When the exhaust gas needs to be discharged, the valve can be opened to allow the exhaust gas to be discharged through the exhaust pipe. However, since the rubber is heated in the barrel to form a liquid, it is easy for the liquid rubber to enter the exhaust pipe when the valve is opened, causing overflow. Moreover, when the exhaust gas is discharged, if it is not filtered and purified, it is easy to pollute the surrounding environment.

[0004] Therefore, it is necessary to invent a rubber extruder. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber extruder, comprising a machine body and a feed hopper, the feed hopper being installed on one side of the upper end of the machine body, a fixed cylinder being installed on the upper end of the machine body, a telescopic component being arranged inside the fixed cylinder, a conveying pipe being installed on the lower end of one side of the fixed cylinder, a processing component being installed on the side of the conveying pipe away from the fixed cylinder, a discharging component being installed on the lower end of the processing component, and a purification component being installed in the middle of the upper end of the processing component.

[0007] Based on the above characteristics: the rubber raw material is introduced into the body through the feed hopper. When the rubber raw material is heated inside the body and turned into liquid for transportation, the telescopic component can be lifted and lowered intermittently. At this time, the exhaust gas inside the body will be sucked into the fixed cylinder for drainage. Then the exhaust gas will be introduced into the treatment component through the delivery pipe. In this process, if the liquid of the rubber raw material is extracted together, the liquid of the rubber raw material will also be introduced into the treatment component through the delivery pipe. Since the liquid of the rubber raw material has gravity, the liquid of the rubber raw material will fall to the bottom of the inner cavity of the treatment component at this time, and finally be discharged back into the inner cavity of the body through the discharge component, while the exhaust gas will flow upward and be discharged after being filtered and purified by the purification component, avoiding overflow and preventing the exhaust gas from polluting the surrounding environment.

[0008] Preferably, an air inlet pipe is installed at the bottom of the fixed cylinder, a fixing plate is fixedly installed at the upper end of the inner cavity of the fixed cylinder, and through holes are opened in the middle of the upper end of the fixed cylinder and in the middle of the fixing plate.

[0009] Based on the above features: the exhaust gas and the liquid of the rubber raw material are introduced into the inner cavity of the fixed cylinder through the air inlet pipe, and the fixed plate and the through hole can limit the telescopic component to keep the telescopic component moving vertically.

[0010] Preferably, the telescopic assembly comprises a telescopic cylinder and a piston rod connected to the lower end of the telescopic cylinder, a buffer spring is sleeved on the outside of the piston rod, and a sealing piston is installed at the lower end of the piston rod.

[0011] Based on the above characteristics: when the piston rod drives the sealing piston to move upward and leak out of the delivery pipe, the exhaust gas and liquid rubber raw material sucked downward will flow into the delivery pipe; when the piston rod drives the sealing piston to move down and block the delivery pipe, the exhaust gas and liquid rubber raw material will not be able to flow into the delivery pipe.

[0012] Preferably, the treatment assembly includes a treatment cylinder, a filter screen and a serpentine heat exchange tube installed in the middle of the treatment cylinder, the serpentine heat exchange tube is located on the upper end of the filter screen, and a plug hole is opened in the middle of the upper end of the treatment cylinder.

[0013] Based on the above characteristics: when the exhaust gas flows upward, it can first be initially filtered through the filter net, and finally it can be cooled by heat exchange through the serpentine heat exchange tube, and finally it can be filtered and purified by the purification component before being discharged to the outside.

[0014] Preferably, a water inlet pipe is installed at one end of the serpentine heat exchange tube, and a water outlet pipe is installed at the other end of the serpentine heat exchange tube.

[0015] Based on the above characteristics: one end of the water inlet pipe and the water outlet pipe are connected to the water pump, and the other end of the water pump is connected to the water storage tank, so that one of the water pumps can pump water and introduce it into the serpentine heat exchange tube through the water inlet pipe. When the serpentine heat exchange tube is cooled after heat exchange, the other water pump can pump out the water after heat exchange in the serpentine heat exchange tube and return it to the water storage tank for secondary use.

[0016] Preferably, the discharge assembly comprises a discharge pipe and a one-way valve installed at the lower end of the discharge pipe, and a guide pipe is installed on one side of the one-way valve.

[0017] Based on the above features: the lower end of the guide tube is connected to the upper end of the machine body, the liquid of the rubber raw material is reintroduced into the interior of the machine body through the discharge pipe and the guide tube, and due to the setting of the one-way valve, the liquid of the rubber raw material in the machine body is prevented from flowing back.

[0018] Preferably, the purification assembly includes a purification cylinder and a screen installed at the bottom of the purification cylinder, activated carbon is installed inside the purification cylinder, and a connecting plate is fixedly installed outside the purification cylinder.

[0019] Based on the above characteristics: after the exhaust gas is filtered and cooled through the filter and serpentine heat exchange tube, the exhaust gas flowing upward will pass through the screen into the purification cylinder, and finally the exhaust gas is purified by the activated carbon adsorption and flows into the external environment.

[0020] The beneficial effects of the utility model are:

[0021] 1. In order to facilitate the discharge of waste gas and avoid overflow, the telescopic cylinder can drive the piston rod and the sealing piston to adjust the telescopic adjustment. When the piston rod drives the sealing piston to move upward and leak out of the delivery pipe, the waste gas and the liquid of the rubber raw material sucked downward will flow into the processing component through the delivery pipe. When the piston rod drives the sealing piston to descend and block the delivery pipe, the waste gas and the liquid of the rubber raw material will not be able to flow into the delivery pipe. Since the liquid of the rubber raw material has gravity, the liquid of the rubber raw material will fall to the bottom of the inner cavity of the processing component at this time, and will be re-introduced into the body through the discharge pipe and the guide pipe. The waste gas will float upward. Due to the setting of the one-way valve, the backflow of the liquid of the rubber raw material in the body can be avoided.

[0022] 2. It is convenient to filter and purify the exhaust gas. When the exhaust gas flows upward, it can first be initially filtered through the filter, and then it can be cooled through the serpentine heat exchange tube. The exhaust gas flowing upward will pass through the screen into the purification cylinder. Finally, the exhaust gas is purified by activated carbon and flows into the external environment to avoid pollution to the surrounding environment caused by exhaust gas discharge.

[0030] The rubber raw material is introduced into the body 1 through the feed hopper 2. When the rubber raw material is heated inside the body 1 and turned into liquid for transportation, the telescopic component 4 can be intermittently lifted and lowered. At this time, the exhaust gas inside the body 1 will be sucked into the fixed cylinder 3 for drainage, and then the exhaust gas will be introduced into the processing component 6 through the delivery pipe 5. In this process, if the liquid of the rubber raw material is extracted together, the liquid of the rubber raw material will also be introduced into the processing component 6 through the delivery pipe 5. Since the liquid of the rubber raw material has gravity, the liquid of the rubber raw material will fall to the bottom of the inner cavity of the processing component 6 at this time, and finally be discharged into the inner cavity of the body 1 through the discharge component 7, while the exhaust gas will flow upward and be discharged after being filtered and purified by the purification component 8, so as to avoid overflow and prevent the exhaust gas from polluting the surrounding environment.

At this time, the piston rod 42 may pass through the through hole 33, so that the buffer spring 43 can be squeezed for elastic buffering when the piston rod 42 is telescoped and adjusted. When the piston rod 42 drives the sealing piston 44 to move up and leak out of the delivery pipe 5, the exhaust gas and the liquid of the rubber raw material sucked downward will flow into the inside of the delivery pipe 5. When the piston rod 42 drives the sealing piston 44 to descend and block the delivery pipe 5, the exhaust gas and the liquid of the rubber raw material will not be able to flow into the inside of the delivery pipe 5.

[0035] Preferably, the treatment assembly 6 includes a treatment cylinder 61 and a filter screen 62 and a serpentine heat exchange tube 63 installed in the middle of the treatment cylinder 61 . The serpentine heat exchange tube 63 is located at the upper end of the filter screen 62 . A plug hole 64 is opened in the middle of the upper end of the treatment cylinder 61 .

[0038] One end of the water inlet pipe 631 and the water outlet pipe 632 are connected to the water pump, and the other end of the water pump is connected to the water storage tank, so that one of the water pumps can pump water and introduce it into the serpentine heat exchange tube 63 through the water inlet pipe 631. After the serpentine heat exchange tube 63 is cooled after heat exchange, the other water pump can extract the heat-exchanged water in the serpentine heat exchange tube 63 and return it to the water storage tank for secondary utilization. The water storage tank and the water pump are not drawn in the figure, which is the prior art and is hereby explained.

When the exhaust gas is filtered and cooled through the filter mesh 62 and the serpentine heat exchange tube 63, the exhaust gas flowing upward will pass through the screen mesh 82 and enter the purification cylinder 81. Finally, the exhaust gas is adsorbed and purified by the activated carbon 83 and flows into the external environment. When the activated carbon 83 needs to be replaced, the screws can be removed or the buckles can be unlocked, and then the purification cylinder 81 can be lifted up to detach from the socket 64, and finally the activated carbon 83 can be taken out and replaced.

[0043] The use process of the utility model is as follows: the rubber raw material is introduced into the body 1 through the feed hopper 2. When the rubber raw material is heated inside the body 1 and turned into liquid for transportation, the telescopic cylinder 41 can drive the piston rod 42 and the sealing piston 44 to telescope and adjust. When the piston rod 42 drives the sealing piston 44 to move upward and leak out of the delivery pipe 5, the waste gas and the liquid of the rubber raw material sucked downward will flow into the delivery pipe 5. When the piston rod 42 drives the sealing piston 44 to descend and block the delivery pipe 5, the waste gas and the liquid of the rubber raw material will not be able to flow into the delivery pipe 5. Then the waste gas will be introduced into the processing component 6 through the delivery pipe 5. During the process, if liquid of the rubber raw material is extracted together, the liquid of the rubber raw material will also be introduced into the processing component 6 through the delivery pipe 5. Since the liquid of the rubber raw material has gravity, the liquid of the rubber raw material will fall to the bottom of the inner cavity of the processing component 6 at this time, and finally be re-introduced into the interior of the body 1 through the discharge pipe 71 and the guide pipe 73. When the exhaust gas flows upward, it can first be initially filtered through the filter screen 62, and then it can be cooled by heat exchange through the serpentine heat exchange tube 63, and the exhaust gas flowing upward will pass through the screen 82 into the purification cylinder 81, and finally the exhaust gas is purified by adsorption of activated carbon 83 and flows to the external environment.
