Chemical delivery systems and methods for delivery of liquid chemicals are disclosed. In on embodiment, systems having multi-reservoir load cell assemblies (Figs. 2, 4, 5, 7, 9, 11) for delivering chemicals used in the semiconductor industry are disclosed. In another embodiment (Fig. 12), the present invention provides a multi reservoir load cell assembly (69, 92, 71), including a controller (PLC), a buffer reservoir (92, 71), a main reservoir (69), one or more load cells (12, 13, 67, 68, 91, 96) coupled to the assembly and to the controller, operable to weigh the liquid in the reservoirs, a plurality of supply lines (A-D), each supply reservoir, and a gas and vacuum sources for withdrawing the liquid from the assembly when demanded by the controller and for refilling the assembly from the supply containers. A proportional valve block including a buffer control Intel (80) and outlet (81) valves adjust the pressure to the buffer reservoirs.

A liquid chemical delivery system for use with a plurality of supply containers (100,102). The system comprising a controller; a multi-reservoir load cell assembly (200), including, a buffer reservoir (208) with a chemical output, a main reservoir (206), a reservoir valve connecting the buffer reservoir to the main reservoir, and a load cell (412), coupled to the assembly and to the controller, operable to weigh the liquid in the reservoir assembly; a plurality of supply lines (306,308), each having a valve coupled to the controller and to one of the supply containers (100,102) to the main reservoir; and means for withdrawing the liquid from the chemical output, opening and closing the reservoir valve, and refilling the main reservoir from the supply containers when demanded by the controller based on signals from the load cell.
摘要:
The invention relates to a method and a device for carrying out chemical and physical processes. The aim of the invention is to be able to carry out such processes with better results and in the same apparatus. To this end, for the initiation of chemical or physical processes the invention provides for at least two liquid media to be injected by means of pumps, preferably high-pressure pumps, into a reactor chamber (5) enclosed by a reactor housing (53) and on to a shared collision point (25), each medium being injected through one nozzle (1). Through an opening (3a) in the reactor chamber a gas, an evaporating liquid, a cooling liquid or a cooling gas is introduced so as to maintain the gas atmosphere in the reactor interior, notably in the collision point (25) of the liquid jets, and to cool the resulting products. The resulting products and excess gas are removed from the reactor housing (53) via a further opening (3) by positive pressure on the gas input side or negative pressure on the product and gas discharge side.

A solution storage and dispensing apparatus and method of operation therefor are disclosed. The solution storage and dispensing apparatus includes a selector valve (68) and a control valve (62) which selectively output a liquid such as water to one of a plurality of storage containers (11a, 11b, 11c, 11d). Each container (11) has an aspirator (26) mounted therein which receives the water and a chemical concentrate to form a solution therein. A container is filled by selecting the container using the selector valve and actuating the control valve to dispense water to the selected container.
