The invention discloses an ion exchange washing alkaline water recycling system, and relates to the field of water treatment. The system comprises an anion exchanger, a washing alkaline water collection pipeline, an online monitoring unit, a shunting switching unit, a weak acid cation exchange treatment unit, an acid liquid regeneration unit, a pipeline conveying pump, a decarburization unit, an intermediate water tank, a recycling unit and a control unit. The online monitoring unit is arranged at the washing drainage end of the anion exchanger, the water quality of the washing alkaline water is detected in real time, and graded recovery of the washing alkaline water is achieved in combination with the shunt switching unit; the recycled washing alkaline water enters a weak acid cation exchange treatment unit to be subjected to ion exchange treatment so as to reduce the alkalinity of the water body; meanwhile, the weak-acid cation exchange resin is regenerated by utilizing acidic waste liquid generated by regeneration of the cation exchange bed, so that synergistic utilization of acid and alkali resources is realized; the treated water body sequentially passes through the decarburization unit and the middle water tank and then is reused for the pure water preparation system.

The invention discloses a multi-stage grinding wheel self-adaptive regulation and control mung bean low-crushing peeling device and method, and relates to the technical field of mung bean peeling, the device comprises a peeling box, speed regulating mechanisms, an adjusting mechanism and a placing box, the upper and lower sides of the front end of the peeling box are fixedly connected with the speed regulating mechanisms, the center of the front end of the peeling box is fixedly connected with the adjusting mechanism, and the adjusting mechanism is fixedly connected with the placing box. A placing box is arranged at the bottom in the peeling box, a speed regulating mechanism is arranged, different groups of convex rods are intermittently matched with a contact wheel, the rotating speed of a grinding wheel is regulated, seed coats are prevented from being adhered to the surface of the grinding wheel due to moisture, and efficient and low-damage peeling of the mung beans is realized; the mounting mechanism is arranged, shells in different shapes are mounted through magnetic adsorption, so that the mung beans generate more complex motion trails in the abrasion process, the contact area of the mung beans and the surface of the grinding wheel is increased, the peeling efficiency is improved, the breakage rate is reduced, meanwhile, the mung beans are better attached to the shapes, and the contact stability of the grinding wheel and the mung beans is improved.

This invention discloses a portable pump with adjustable length, comprising a front rod, a tail rod, and at least one intermediate rod. The front rod has a pump head assembly, and the tail rod has a handle assembly connected to its tail end. The tail end of the front rod has a first connecting piece, one end of the intermediate rod has a first connecting piece, the other end has a second connecting piece, and the front end of the tail rod has a second connecting piece. The first and second connecting pieces are detachably connected. The pump head assembly includes a motor mounting base, a motor, an impeller, and a filter. The motor mounting base is fixedly connected to the front rod, and the motor is fixed within the motor mounting base. The impeller is detachably mounted on the motor's output shaft, and the filter is detachably mounted on the motor mounting base. This invention allows for flexible adjustment of the overall pump length to adapt to different usage scenarios by selecting different numbers of intermediate rods for splicing. Simultaneously, both the impeller and filter adopt a tool-free, detachable structure, facilitating daily cleaning and maintenance for users, significantly improving operational convenience and equipment reliability.

The invention discloses a cache consistency maintenance method and device, equipment, a medium and a program product, and relates to the technical field of computers. After receiving a cache consistency write operation request of a first request node of which the initial state is an invalid state, a main node firstly returns a response message; initiating an invalid monitoring request carrying a target cache line data demand inquiry to other request nodes, receiving a monitoring response carrying own data demand information returned by each node, accurately sensing and recording the actual data demand of each node, and avoiding the problem of bus load increase; on the basis of the updated directory entry, the target cache line data is only distributed to the node with the data demand without waiting for the data demand node to re-initiate the data reading operation, so that the bus communication overhead can be effectively reduced, the process of the read-after-write operation of the multi-core system is simplified, the operation delay is reduced, the cache data consistency among the multiple nodes is ensured, and the data reading efficiency is improved. And the execution efficiency of the read-after-write operation in the shared memory system is obviously improved.
