A lip type seal consisting of parts which can be easily separated and sorted by material to facilitate recycling of the parts. A lip type seal provided with a mechanism for preventing rotation of constituent parts is also provided. The lip type seal has a first lip seal member constructed from a rubber-like elastic body, a metal-made holding ring fitted and held at the first lip member without bonding, and a resin-made second lip seal member and a backup ring which are held at the holding ring by staking. The first lip seal member has a tubular section, a radial section, a seal lip, and a flange section. The holding ring has a circular tube section, a first flange section, and a second flange section, and the second lip seal member and the backup ring are held between both the first and second flange sections by staking. A protrusion is provided at a position in the circumferential direction of the first flange section of the holding ring, and the protrusion engages with the second lip seal member to prevent rotation of the second lip seal member.

To facilitate recycling and prevent rotation of constituent parts, a lip type seal has a first lip seal member constructed from a rubber-like elastic material, a metal-made retaining ring held at the first lip seal member without bonding, and a resin-made second lip seal member and a backup ring which are held at the retaining ring by caulking. The first lip seal member has a tubular portion, a radial portion, a seal lip, and a collar portion. The retaining ring has a cylinder portion, a first flange portion, and a second flange portion, and the second lip seal member and the backup ring are held between the first and second flange portions by caulking. A convex portion is provided at a position in the circumferential direction of the first flange portion, and the convex portion engages with the second lip seal member to prevent rotation of the second lip seal member.

The invention discloses a method for treating waste water generated from surface treatment of aluminum products, which realizes the treatment of waste water generated during each step of surface treatment of the aluminum products. The waste water generated from the treatment process comprises sulfuric acid oil removal rinsing waste water, three acids treated rinsing waste water, ammonium bifluoride pickling rinsing waste water, alkali washing rinsing waste water, nitric acid neutralized rinsing waste water, sulfuric acid anodized rinsing waste water, nickel plating rinsing waste water and acetic acid hole sealing rinsing waste water. The method of the invention aims at the treatment of waste water generated by all the steps in the surface treatment, a set of integrated technology flow is formed, the method is easy to be used for enterprises; the properties of various waste water can be utilized with a large degree, the usage of an auxiliary agent can be reduced by mutual reaction and mutual deposition, and the cost can be reduced.

The invention discloses a treatment and resource-utilizing technology of the production wastewater of tert-butyl peroxy benzoate (initiator is C). The technology is as follows: high concentration production wastewater is collected from the sewage outlet of a production device to perform stabilization treatment, and after the risk that the organic peroxide in wastewater is violently decomposed when heated is basically eliminated, the mixture of tertiary butanol and tert-butyl peroxide, sulfuric acid, benzoic acid and sodium chloride are recycled from wastewater. the mixture of tertiary butanoland tert-butyl peroxide, benzoic acid and sulfuric acid can be used repeatedly in production and sodium chloride is a by-product. After most of tertiary butanol and tert-butyl peroxide are removed and benzoic acid, sulfuric acid and sodium chloride are recycled, the wastewater performs hydrolysis-contact oxidation and C-Fe micro-electrolysis decoloring treatment and the main indexes of dischargedwater meet the requirements of the discharge standard of water pollutants for pharmaceutical industry chemical synthesis products category (GB21904-2008) on the water pollutants emission limits of new business.

The invention discloses a method for treating waste material containing abrasive grains, which comprises: obtaining a waste material solution containing abrasive grains, and the abrasive grains are used to fix the surface of a wire saw; using a filter to filter out first impurities in the waste material solution to obtain The first abrasive particle solution, the average particle diameter of the first impurity is greater than the average particle diameter of the abrasive particles; ultrasonic treatment is performed on the first abrasive particle solution to peel off the second impurity on the surface of the abrasive particles, and the first abrasive particle solution The second impurity is removed from the first abrasive solution to obtain a second abrasive solution; the abrasive particles in the second abrasive solution are subjected to surface active treatment with an active agent and the abrasive particles are extracted. The method of the invention can achieve the purpose of purifying and optimizing the diamond surface state, so that the recovered diamond powder can be reused, the utilization rate can be improved, and the sanding ability and uniformity can be further improved.

The invention discloses a crushing detachable combined type rag cutting machine. The crushing detachable combined type rag cutting machine includes a crushing type rag cutting machine and a detachable type rag cutting machine, wherein the crushing type rag cutting machine and the detachable type rag cutting machine are connected through through-holes. The crushing type rag cutting machine is internally provided with rag cutting rollers, a cylinder surface of each rag cutting roller is provided with rag cutting blades, and the rag cutting rollers are internally provided with rotating shafts; two sides of the crushing type rag cutting machine are provided with a first air blower and a second air blower respectively; a crushing type rag cutting machine discharge pipe is arranged on the bottom of the crushing type rag cutting machine; and the crushing type rag cutting machine and the crushing type rag cutting machine discharge pipe are connected through a crushing type rag cutting machine valve. The crushing detachable combined type rag cutting machine combines the crushing type rag cutting machine with the detachable type rag cutting machine, and can meet different rag cutting requirements during textile processing; through combination of the crushing type rag cutting machine and the detachable type rag cutting machine, the efficiency of rag cutting can be effectively improved; and the crushing type rag cutting machine and the detachable type rag cutting machine are connected through the through-holes, so that two kinds of rag cutting can be performed at the same time, and the rag cutting is more thoroughly.
