The invention relates to a silica sand producing device, namely a differential pressure type evacuation preventing mortar pump. The differential pressure type evacuation preventing mortar pump comprises a mortar tank (2) and a mortar pump body (6), and the inlet of the mortar pump body (6) is located at the lower portion in the mortar tank (2). The differential pressure type evacuation preventing mortar pump is characterized in that a partition plate (3) is arranged in the mortar tank (2) and divides the space in the tank into a main cavity (4) and an auxiliary cavity (5), a notch (10) is formed in the upper portion of the partition plate (3), a water draining hole (8) is formed in the lower portion of the partition plate (3), a differential pressure valve (9) is installed on the part, on one side of the water draining hole (8) and the main cavity (4), of the partition plate (3), the differential pressure valve (9) is provided with a tubular sliding sleeve (11), an end cover (12) is arranged at the outer end of the sliding sleeve (11), a water draining port (14) is formed in the lower side wall of the sliding sleeve (11), a piston disk (15) is arranged in the sliding sleeve (11), and the inner side face of the piston disk (15) and a plate face around the water draining hole (8) are closed matched faces. The differential pressure type evacuation preventing mortar pump has the advantages that in the working process of the mortar pump, a part of mortar or clean water is stored in the auxiliary cavity, when the liquid face of the mortar in the main cavity ascends to the appointed position, the differential pressure valve is automatically opened, the mortar is supplemented in the main cavity, mortar pump evacuation is avoided, and the stable work of the mortar pump is ensured.

The invention provides a cap of a photoresist bottle and the photoresist bottle. The cap of the photoresist bottle comprises a bottle cap body, a cap core, a cover plate and a photoresist tube guide locking piece. The bottle cap body is connected with the opening of the photoresist bottle in a threaded mode through threads on the inner side of the lower portion of the bottle cap body. The cap core is located above the opening and on the inner side of the upper portion of the bottle cap body. The cover plate is located above the bottle cap body and the cap core and fixed to the cap core. An annular groove is formed between the cover plate and the cap core, the front end of the upper portion of the bottle cap body is embedded into the annular groove, and therefore the bottle cap body and the cover plate can neither be separated nor rotate independently, and the bottle cap body and the cap core can neither be separated nor rotate independently. Vertically-through holes are formed in the cap core and the cover plate, the photoresist tube guide locking piece penetrates through the holes and is fixed to the cap core and / or the cover plate in a threaded mode. The photoresist tube guide locking piece is hollow, and a photoresist tube guiding photoresist penetrates through the photoresist tube guide locking piece to be inserted into the photoresist bottle by a proper depth and is fixed to bottle cap body in a locking mode. According to the cap of the photoresist bottle and the photoresist bottle, the photoresist tube can be fixed to the cap of the photoresist bottle, evacuation caused when the photoresist tube can not be inserted to the bottom of the photoresist bottle is prevented, and therefore photoresist shortage of wafers is avoided.

The invention discloses an offset printing fountain solution self-circulation purification system and method. The system comprises a first water tank, a second water tank, a layered deposition filter, a filter, a third water tank and a control circuit. When through the control circuit, it is found that particle solubility of a fountain solution in the first water tank is less than a preset value, the control circuit controls a 3-way shift switch so that the fountain solution flows into a first chamber, when through the control circuit, it is found that particle solubility of the fountain solution in the first water tank is greater than the preset value, the control circuit controls the 3-way shift switch so that the fountain solution goes through the layered deposition filter, flows into the first chamber, then enters a self-circulation filter system and is subjected to cyclic purification, the control circuit receives signals of a thermometer, a pH detector and a conductivity detector, and when the pH and the conductivity are higher than a corresponding pH threshold and a conductivity threshold, alcohol and water are added into the primary fountain solution according to a certain ratio. The system and method have high fountain solution purification efficiency, realize real-time accurate detection of indexes of the fountain solution, make the fountain solution quality stable and guarantee printing quality.

The application provides a cutting machine including: a frame, a clamping mechanism, a hob device, a driving wheel and a power device. The hob unit includes: a cutting wheel seat, a cutting wheel assembly and a driving assembly. In the cutting machine provided by this application, the pipe is clamped on the hob device, so that the side wall of the pipe is close to the middle position of the cutting wheel assembly, the cut of the cutting wheel assembly is perpendicular to the pipe, and then the cutting wheel seat and the driving assembly move, Make the blade of the cutting wheel assembly cut into the pipe wall, and the power device drives the cutting wheel assembly to rotate around the pipe through the driving wheel. With the advancement of the driving assembly, the continuous feeding will roll and cut the pipe until the pipe is cut off. During the process, no iron filings are formed, which reduces the loss of pipes. The cutting wheel assembly is used to cut the pipe by rolling, and the contact mode between the blade of the cutting wheel assembly and the raised ribs inside the pipe changes, that is, the blade does not directly form impact contact with the ribs, which reduces the damage of the blade accordingly probability.

The embodiment of the present invention discloses a short-distance information exchange method and system, information sending and receiving equipment, and a terminal, wherein the method includes: receiving an information sending request, and the information sending request includes information to be transmitted; Encoding, converting the information to be transmitted into a Morse code digital signal, including Morse numbers and / or Morse letters; according to the Morse code encoding table, performing D / A conversion on the Morse code digital signal, converting The Morse code digital signal is converted into a Morse code sequence, and a character space is added between two adjacent Morse codes to obtain a Morse code analog signal; the Morse code sequence includes more than one sequence of Morse codes Telecode; Morse code analogue signal sent as Morse radio sound. The embodiments of the present invention can reduce the cumbersome operation of pairing between user terminals sharing information, reduce information transmission time, and improve information exchange efficiency.
