Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a special separator for colloid storage batteries. Background Art

[0002] The known storage battery is a lead-acid storage battery, the electrolyte of which is sulfuric acid, which easily causes environmental pollution, has low storage capacity and short service life. Later, people invented a colloidal storage battery, which is mainly composed of a battery tank, a plate, a separator and a colloidal silica electrolyte.

[0003] The problem of uneven electrolyte density is easy to occur in silica colloidal electrolyte during filling, and the colloid needs to be guided, especially at the partition where it is easy to accumulate, and ribs need to be used for guidance and diversion. The existing ribs are fixed on the partition, which is easy to cause suffocation during filling and produce bubbles, which is extremely harmful.

[0004] For this reason, we propose a separator specially used for colloidal batteries. Utility Model Content

[0007] Preferably, the height distance between the two groups of limit posts is the same as the thickness of the partition plate, and the left-right distance between the two groups of limit posts is 0.8 times the thickness of the partition plate.

[0008] Preferably, a bracket is fixedly mounted on the base plate at a position corresponding to the right side of the limiting ring, and the top surface of the bracket is parallel to the bottom end of the first guide plate in a horizontal state.

[0011] Preferably, a hollow buoyancy cylinder is fixedly mounted on the bottom end surface of the second guide plate.

[0012] Preferably, a limiting ball is fixedly installed on the front end surface of the limiting column. The limiting ball is a hemispherical structure. A limiting plate is clamped on the limiting ball. The limiting plate is provided with a slot corresponding to the position of the limiting ball. The slot cooperates with the limiting ball, and the diameter of the limiting plate is the same as the diameter of the limiting ring.

[0013] Beneficial Effects

[0014] The utility model provides a separator specially used for colloidal batteries, which has the following beneficial effects:

[0015] (1) The colloidal battery separator uses a rotating structure composed of two sets of limiting columns, a dividing plate and a limiting ring. This simple and easy-to-produce rotating structure can guide the silica colloidal electrolyte to flow evenly when the battery is filled.

[0016] (2) The separator for colloidal batteries changes its angle as the silica colloidal electrolyte is filled and rises. With the cooperation of the buoyancy tube and the bracket, the first guide plate and the second guide plate are finally in a horizontal state, so that the liquid surface of the silica colloidal electrolyte is stable and the accumulation is reduced.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment: A separator for colloidal batteries, such as Figure 1-Figure 4 As shown, it includes a substrate 1, and a plurality of guide units are evenly distributed on the side wall surface of the substrate 1, and the guide units include two groups of limit columns 2, and a dividing plate 3 is arranged between the two groups of limit columns 2. A limit ring 4 is fixedly installed on the outside of the dividing plate 3, and the limit ring 4 is sleeved on the outside of the two groups of limit columns 2. The dividing plate 3 divides the limit ring 4 into two spaces, and the two groups of limit columns 2 are respectively located in the two spaces. The outer wall surface of the limit ring 4 is symmetrically fixed with a first guide plate 5 and a second guide plate 6, which are used to guide the uniform flow of the silica colloidal electrolyte during filling. This structure can realize that the first guide plate 5 and the second guide plate 6 rise with the filled silica colloidal electrolyte, change their own angles, and assist in stabilizing the liquid level of the silica colloidal electrolyte and reducing accumulation.

[0027] The height distance between the two groups of limiting columns 2 is the same as the thickness of the dividing plate 3 , so that the two groups of limiting columns 2 will not interfere with the horizontal placement of the dividing plate 3 .

[0028] The left-right distance between the two groups of limiting posts 2 is 0.8 times the thickness of the partition plate 3, so that when the partition plate 3 is tilted, an inclination angle of less than 90 degrees is formed between the two groups of limiting posts 2, which is 75 degrees in this embodiment.

[0029] The inner wall surface of the limiting ring 4 is in contact with the two groups, so that the rotation center of the dividing plate 3 and the limiting ring 4 remains unchanged during the rotation process.

[0030] The length of the first guide plate 5 is 0.8 times the length of the second guide plate 6, so that the weight of the first guide plate 5 is less than that of the second guide plate 6, and the second guide plate 6 is tilted downward, so that the initial position of the guide unit is tilted for guiding the silica colloidal electrolyte.

[0031] A hollow buoyancy cylinder 7 is fixedly mounted on the bottom end surface of the second guide plate 6 to generate buoyancy during the rising process of the silica colloidal electrolyte, thereby changing the angle of the first guide plate 5 and the second guide plate 6 to achieve a mixing effect.

[0032] A bracket 8 is fixedly installed at the position of the base plate 1 corresponding to the right side of the limit ring 4. The top surface of the bracket 8 is parallel to the bottom end of the first guide plate 5 in the horizontal state, supporting the first guide plate 5. With the cooperation of the buoyancy cylinder 7 and the bracket 8, the guide unit is finally in a horizontal state.

[0033] The front end surface of the limiting column 2 is fixedly installed with a limiting ball 9, and the limiting ball 9 is a hemispherical structure. The limiting ball 9 is clamped with a limiting plate 10, and the limiting plate 10 is provided with a slot 11 corresponding to the position of the limiting ball 9. The slot 11 cooperates with the limiting ball 9. The diameter of the limiting plate 10 is the same as the diameter of the limiting ring 4, so as to axially limit the limiting ring 4.

[0034] The working principle of the utility model is as follows: a rotating structure composed of two groups of limit columns 2, a dividing plate 3 and a limit ring 4 is utilized. This simple and easy-to-produce rotating structure can guide the silica colloidal electrolyte to flow evenly during battery filling. As the filled silica colloidal electrolyte rises, its own angle is changed. With the cooperation of the buoyancy cylinder 7 and the bracket 8, the first guide plate 5 and the second guide plate 6 are finally in a horizontal state, so that the liquid level of the silica colloidal electrolyte is stable and accumulation is reduced.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
