A blow molding machine for containers, having a conveyor path carrying a mandrel holder and pre-forming mandrels attached to the mandrel holders in an exchangeable manner by means of removable couplings, wherein each coupling has a mandrel clamping mechanism and a releasing element accessible form outside that can be adjusted at least relative to the mandrel holder for releasing the clamping mechanism. In the mandrel holder, particularly for use in a blow molding machine, the mandrel clamping mechanism is designed with a ball joint lock, and the ball joint lock can be released by means of a releasing element in order to exchange a performing mandrel.

The invention discloses a novel floor mat which comprises a plurality of hairbrushes for cleaning, a plurality of frames for containing the hairbrushes, and rubber connecting strips. The frames are mutually independent, and the adjacent frames are connected through the rubber connecting strips. By the adoption of the structure, the mode that in the prior art, steel wires are connected in series connection in a floor mat is replaced, the replacement and the maintenance of the hairbrushes are convenient, the replacement time is short, the workloads are small, the whole disassembly is convenient, the novel floor mat is attractive and elegant, and the manufacturing process is simpler.

The invention relates to a tubular concentration device in the manufacturing field of papermaking, brewing and sludge treatment industrial equipment. The tubular concentration device comprises a base and a cylinder, wherein a feed hole and a discharge hole are formed in the cylinder; filter pipes are arranged in the cylinder; the upper parts of the filter pipes are communicated with straight pipes; filtrate outlets, gas inlets and vibrators are arranged on the straight pipes; the outer surface of each filter pipe is coated with a screen which is further sleeved with a filter bag; the straight pipes are elastically connected with the upper end surface of the cylinder; or every 2-50 straight pipes are connected in parallel to form a group, each group is provided with one vibrator, and the filtrate outlets and the gas inlets of the straight pipes are gathered as one; when in use, each filter pipe is subjected to cake removal in turn while other filter pipes work normally; the feed hole is continuously opened, and the discharge hole is opened for discharging once at an interval of certain time; since the upper parts of the straight pipes are connected with the vibrators and provided with the gas inlets, vibration as well as blowing is performed in cake removal, and the drop speed of filter cakes is increased; the outer surface of each filter pipe is coated with the screen and the filter bag to form a porous filter layer with certain thickness, the concentration filtration is smooth and the service life of the filter bag is long.
