The invention discloses a novel internet screen-free express delivery cabinet system. The novel internet screen-free express delivery cabinet system comprises a screen-free express delivery cabinet, a handheld mobile terminal and a background server, wherein the screen-free express delivery cabinet is connected with the background server in a wired or wireless manner; the handheld mobile terminal accesses the background server in a wireless linkage manner; the background server receives a temporary storage or sending request from the handheld mobile terminal, then takes parameters from a background database and sends a message to the screen-free express delivery cabinet through a wired or wireless network; after receiving the message, the screen-free express delivery cabinet opens a corresponding grid to enable an owner or a courier to take an express item away or store the express item. The novel internet screen-free express delivery cabinet system has the benefits that a mobile internet technology is added, and the experience of a user is optimized; the screen-free express delivery cabinet is operated to be opened and closed by using the handheld mobile terminal, the environment limitation of an intelligent express delivery cabinet is broken, and the coverage temperature range is expanded to be minus 25 DEG C to 85 DEG C; compared with the conventional intelligent express delivery cabinet with a screen, the novel internet screen-free express delivery cabinet system has the advantages that the cost is lower, the total cost is reduced by about 40 percent, and the service life is longer.

A screenless reactor design is presented. The reactor includes a series of overlapping vanes where solid catalyst can cascade down the vanes. Gas flows across the catalyst by flowing through the vanes contacting the catalyst and then disengaging from contact with the solid catalyst particles.

The invention relates to a flow-washing-type battery material dryer free of a screen cloth. The flow-washing-type battery material dryer free of the screen cloth is characterized in that the dryer comprises a support, a spiral material feeder, a first flange plate, a discharging pipe, an air cylinder, a material dropping plate, a sealing piston, a weighing device, a second flange plate, a Venturi branched tube, an airflow tank, a return air tank, a feeding pipe, a cyclone air outlet pipe, an air return pipe, a vacuum pumping pipe, a reflux tank, a Venturi tube and a third flange plate; the airflow tank comprises an upper airflow tank section and a lower airflow tank section, and the upper airflow tank section and the lower airflow tank section communicate with each other; the reflux tank is arranged at the outer side of the upper portion of the upper airflow tank section in a sleeving mode; the upper end of a space between the reflux tank and the upper airflow tank section is closed, and the lower end of the space is opened; and the reflux tank is of a cylinder structure with the cross section circle variable. According to the flow-washing-type battery material dryer, the return air tank, the reflux tank, the airflow tank and the Venturi tube are sequentially nested from outside to inside, so that the heat preservation effect of the dryer is made good; and moreover, heat is transmitted between the multiple layers of the pipes, after all layers of pipe walls are heated by hot air, the heat can be radiated outwards from the pipe walls, and powder drying is accelerated.

The invention discloses an intelligent touch projection system, which includes a touch laser set and a projector used in cooperation with each other. The projection screen of the projector is located in the shooting area of ​​the camera. Control receiver, the screenless touch laser is installed on a fixed body, the fixed body has a touch surface, the light emitted by the screenless touch laser is parallel to the touch surface, the screenless touch receiver receives the projection screen of the projector, and the host is installed There is a positioning software to touch the projection screen of the projector to operate the opening and disconnection between the screen transmitter and the projector. The writing software is installed in the main unit, and the information of the writing software is projected to the touch surface to solve the incompatibility of software and hardware products in the current market and provide customers with one-stop service.

A secondary containment system is used with a screenless reactor. The secondary containment system includes a screen sized to prevent the passage of catalyst particles, and is affixed to the screenless reactor with supports to hold the screen a desired distance from the reactor.
