The invention discloses a same-direction self-cleaned twin-screw extruder with baffle plates and a processing method thereof. A screw mechanism of the same-direction self-cleaned twin-screw extruder comprises a first screw rod and a second screw rod, wherein the first screw rod is in a single thread structure, and the second screw rod is in a double thread structure; the baffle plates are arranged in the screw grooves of the first screw rod, and the height of each baffle plate is less than the depth of each screw groove of the fist screw rod; 8-shaped hyperbolic flow disturbance can be formed at the baffle plates in the screw grooves of the first screw rod; and the first screw rod and the second screw rod rotate at the same speed, are meshed with each other at all times and are self-cleaned simultaneously. According to the processing method, the screw grooves are triggered under the action of 8-shaped hyperbolic flow disturbance formed due to the arrangement of the baffle plates to mix materials chaotically all the way, two flowing ways formed by the two screw rods fulfill the topological chaotic mixing function of dividing materials into two parts, mixing the two parts of materials and dividing the mixture into two parts, and the first screw rod and the second screw rod fulfill the functions of compressing, expanding, recompressing and reexpanding periodically. Under the joint action of three reinforced mixing mechanisms, the materials can be molten and mixed efficiently.

The invention discloses an air shower type quick drying device for food vacuum packaging, which not only realizes the air shower drying from the top, but also realizes the air shower drying from the bottom, which can greatly improve the air shower drying ability. The setting of the shower assembly that can continuously swing back and forth around the horizontal direction can effectively improve the drying ability of the air shower and the performance of the air flow. The wind mechanism can automatically clean the filter screen group inside itself, which can effectively improve the self-cleaning ability of the filter screen group, improve the performance of the air shower airflow, and ensure the air shower effect. The present invention can conveniently realize the self-cleaning effect and self-cleaning ability of the filter net group by setting the self-cleaning control and locking component and the transmission control component, and can realize regular self-cleaning to ensure the effect.

The present invention relates to a 5G communication base station, comprising: a steel frame tower, base station communication equipment arranged in the steel frame tower, and an outer cover fixedly connected to the steel frame tower and wrapping the steel frame tower. The 5G communication base station of the present invention has a high self-cleaning effect, can use high hydrophobic materials to realize water droplets rolling freely on the hydrophobic surface, can take away dust and particles during the rolling process, and can be used outdoors for a long time, significantly The dust adhesion of the outer cover is reduced, the operation is simple, the cost is low, and it can meet the needs of 5G communication.

The invention discloses a self-sewage-cleaning type spiral plate sewage heat exchanger. According to the heat exchanger, a sewage heat exchange wide flow way and a clean water heat exchange narrow flow way in a shell are wound around in a side-by-side manner to form a spiral heat exchange main body, and a plurality of sewage cleaning units and sewage discharging plates are formed in the spiral heat exchange main body, wherein the inner side surface of an outer side spiral plate of the sewage heat exchange wide flow way is provided with the protruding arc-shaped guide plates, and the arc-shaped guide plates are combined to form the sewage cleaning units; and the sewage discharging plates are evenly distributed at the lower ends of the sewage cleaning units, and inclined angles are formed between the sewage discharging plates and the horizontal direction. According to the heat exchanger, sewage bonded on the sewage wide flow way heat exchange plate can be effectively cleaned up, happening of a scale formation hanging wall is obstructed, and self sewage cleaning can be reliably achieved. Continuous sewage discharging can be achieved, and secondary appearing of sewage is prevented. The self-sewage-cleaning type spiral plate sewage heat exchanger has the prominent substantive beneficial effects and obvious advantages of being novel and unique in conception, compact and reasonable in structural design, stable and reliable in work performance, excellent in scale prevention and sewage cleaning effect, economical, practical, energy-saving, efficient, and capable of obviously improving the heat exchange efficiency and obviously prolonging the service life. The self-sewage-cleaning type spiral plate sewage heat exchanger is the most ideal sewage heat exchange equipment in the field at present.

The invention belongs to the technical field of rainwater filtering devices, and in particular relates to a non-powered self-cleaning rainwater filtering device, which includes a water inlet three-way pipe connected to a water inlet rainwater pipeline, a water storage pipe and a four-way pipe for water storage An inlet pipe is installed on the top of the pipe, a filter is installed on the bottom, and one end of the backwash pipeline is connected to the inside. The backwash pipeline includes a vertical pipe, an upper elbow, a horizontal pipe, a Venturi tube, and a lower elbow, and the other end of the backwash pipeline The connected drain pipe is connected with a four-way pipe, the bottom side of the drain pipe is connected to the four-way pipe through the seepage pipeline, the bottom of the drain pipe is connected to the outlet rainwater pipeline, the flange blind plate connected to the top of the four-way pipe is connected to the top of the connecting frame, and the bottom of the connecting frame A filter basket is installed at the end of the cross pipe, and a filter plate is installed at the end of the four-way pipe facing the drain pipe. The combined design is low in cost and easy to assemble, which is conducive to the transportation, storage and popularization of the device. The tube speeds up and sprays out from the lower elbow to realize non-powered backwashing of the filter plate.
